Figure 2 explains the location code transmitting and receiving device.
Figure (A) shows a transmitter that is installed in each region, tourist spot, event venue, etc. and transmits a location code.
) indicates a receiver installed in the camera body that receives the location code.

In the figure (A>), the ROM 201 has a location code, for example, a location (event) identification code, a Kanji JIS code string of the location (event) name, or both, written in advance.DPSK modulation section 202 is 8
The output code data from 0M201 applies differential phase modulation (DPSK) to the carrier wave.
Phase 5hurt 1 (eyeing) is applied. The FM modulation section 203 performs FM modulation on the carrier wave based on the input serial data, and further performs FM modulation on the carrier wave using the input serial data.
After being amplified to a predetermined power, the signal is transmitted from the antenna 205 as an FM radio wave including a location code.

A timing generation circuit 206 generates the timing of each block on the transmitter side, and outputs read address data to the ROM 201 and clock pulse GK to the DPSK modulation section 202 and FM conversion section 203.

Note that the DPSK modulation is performed by the timing generation circuit 20.
AFM in the possible Ii range using 6 clock pulses CK,
Phase difference data is extracted from digital data using a medium wave MFM or PLL method, and is converted into serial data.

A demodulator 208 removes the carrier frequency, and a next-stage DPSKII modulator 209 demodulates the data to the original code data. , the CPU 20 takes in the demodulated code data and stores it in the memory card 26. That is, C
The PU 20 writes the code data to the memory card 26 in association with the writing of the photographed image at that time. The timing generation circuit 210 controls the timing of each block on the receiver side, and in response to the control signal from the CPLJ 20, the FM review section 208, DPSK1! [1
A clock pulse GK is output to the first section 209.

Therefore, when a camera image is taken at a location where the transmitter is installed, such as a certain area, tourist spot, or event venue, the location code is automatically stored in the memory card.

The ROM 201 may be one that stores only a location code specific to that location, or one that has multiple location codes written in advance and can be switched to output the location code depending on the installation location. But that's fine.

FIG. 3 is a detailed block diagram of the GPS receiver 23.

The antenna 23a receives transmitted radio waves from a star NAVASTARII (not shown), for example, a quadrifilar helix <auadrifilar he! iX) type. The RF signal received by the antenna 23a is input to the RF signal mixer 230. On the other hand, the modulator 231 converts the local oscillation signal CK1 from the local oscillator 232 into a PN coco generator 2.
33, and the spread modulation signal is input to the mixer 230. As a result, the IF multiplied signal, which is the intermediate frequency of the RF multiplied signal, is converted and inputted to the data demodulation circuit 234.

This data demodulation circuit 234 demodulates data including the time when the satellite transmits the signal from the input signal. The demodulated data is input to a data processing circuit 235 and a delay measurement circuit 236.

The delay measuring circuit 236 first outputs a timing signal to the PN coco generator 233 when demodulated data is input. The PN code generator 233 is always PN by the clock pulse CK2 from the PN code clock generator 237.
A code is generated, and when the timing signal is input, the generated PN code is sent to the delay measurement circuit 236. And data demodulation circuit 234
PN code from and PN from PN code generator 233
The code is led to a delay measuring circuit 236, and the delay time of the PN code necessary for correlation between both PN codes is measured. The delay time of this PN code is determined by the measurement clock generator 238.
The counted value is outputted from the delay measuring circuit 236 to the data processing circuit 235 as delay data necessary for correlating both PN codes.

The data processing circuit 235 is composed of a microprocessor, is driven by the clock pulse CK4 from the data processing clock generation circuit 239, and has a built-in GPS receiver and transmission time data included in the demodulated data from the data demodulation circuit 234. From reception time data obtained from a cesium and rubidium vapor atomic clock (not shown)! Find the radio wave propagation time from to the GPS receiver (camera),
The distance from the satellite to the GPS receiver (camera) is calculated from this time. Then, the data processing circuit 235 uses the distance information from each satellite and the position information of each satellite itself included in the demodulated data to
Calculate and obtain position information regarding 1 degree, longitude and altitude,
Output to CPLI20.

As is well known, GPS is a system that covers the entire world using 18 NAVASTARs, but currently not all satellites have been launched, and there are areas where reception is not possible or where reception is unavailable depending on the time of day. The CPU 20 automatically stores location code data from the location code receiver in areas where reception is not possible, while storing data from the satellite when no location code transmitter is installed and no location code is received. Both receivers are controlled so that they receive data, take in the received data as position information, and interpolate each other.

FIG. 4 is a flowchart explaining the operation of the camera.

In step #1, a power supply (not shown) is turned on, and
When the power is turned on (YES in step #1), the presence or absence of the memory card 26 is determined (step #2). If there is no memory card 26, a message indicating that there is no card is displayed and a warning that photographing (recording) is not possible is performed, and the process returns to step #1 (step #3, step #4). In this case, the camera may have a memory capable of recording a plurality of frames in addition to the memory card 26.

If the memory card 26 is installed, "card present" is displayed (step #5), and then the usage status of the memory card 26, that is, the presence or absence of recordable free space is detected (step #6). ). If there is no free space (
(YES in step #7), a warning is issued indicating that recording is not possible, and the process returns to step #1. Note that, as described above, when a built-in memory for a plurality of frames is provided, whether or not recording is not possible may be determined in consideration of the presence or absence of free space in the built-in memory.

On the other hand, if recording is possible (No in step #7>, m

When the input operation of shooting information from each of the above sensors etc. is completed,
Next, it is determined whether or not the exposure start switch S2 is on (step #17). Above switch S2
If not on (No in step #17), the process advances to step #18 and the state of the switch S1 is checked again.

Here, if switch S1 is on (step #18
If the switch S1 is off (No in step #18), the process returns to step #10 and sensing is performed again using the sensors, etc., in order to obtain more accurate photographic information immediately before the photograph is taken. , it is determined that photography has been canceled, and the process returns to step #1.

If switch S2 is on (YES in step #17)
), the distance measurement data is locked, and then focal length information f from the lens 1 and object distance information from the AFCPU 16 are stored (step #19 and step #20).

Then, the colorimetric data obtained by the WB sensor 14 is locked, and then the voice input operation using the microphone 10 is started (Step #21. Step #22). Further, in parallel with this operation, exposure is performed (step #23), and when the exposure is completed (YES in step #24), predetermined signal processing for capturing the photographed image is started (step #25). .

Next, in step #26, the audio input selector switch S3 is turned on.
It is determined whether or not the switch S3 is on, and if the switch S3 is on (YES in step #26), all audio is captured (step #27), and if it is not on (no in step #26), For example, only one second of audio is captured as H recognition (step #28).

After the above operations, image data, audio data, search information (W/1 shadow information) obtained from each sensor, etc. are written into the memory card 26 in a corresponding format (see FIG. 27).
Step #29), the free space information on the memory card 26 is updated, and the frame number is counted up by 1 (step #30 and step #31) to prepare for the next photographing.

FIG. 5 is a block diagram showing an example of a photographed image playback device equipped with a search function.

This reproducing machine is centrally controlled by a CPU 50. This CPU 50 is programmed in advance to perform various control functions in accordance with the content of each search and reproduction process described later.

The memory card I/F 51 is used to guide recorded images, search information, and data regarding the usage status of the memory card 26 from the memory card 26 to the reproducing machine, and also to guide read image selection data from the reproducing machine to the memory card 26. This is the interface. The special reproduction processing section 52 performs special processing on the image read out from the memory card 26 as will be described later, and the image data processed by the special reproduction processing section 52 is temporarily stored in the image frame memory 53. . The combining unit 54 combines image data with a superimposed image, which will be described later, and is switched and controlled by an on-screen display 0N10FF switching control signal from the CPU 50. The synthesized image signal is sent to the OA converter 5
The signal is converted into an analog signal at step 5, and further amplified at the next stage amplifier 56, and then guided to a TV monitor 57 for reproduction and display.

The superimpose memory 58 stores various search information and on-screen display patterns such as scales. The read clock generation circuit 59 supplies clock pulses for read timing to the image frame memory 53, the synthesis section 54, the DA converter 55, and the superimpose memory 58, respectively.

The character generator 60 stores the character font of the Japanese Industrial Standard JIS code string, and outputs the corresponding character code to the CPU 50 when the JIS code string is adopted as the location code. The filing device 61 is composed of a recording medium such as an optical disk and its driving circuit, and is a so-called album that appropriately records recorded images in the memory card 26. This filing device!
61 is read and written under control by the CPU 50, records images and registration search information, and outputs registration search information and disk management information to the CPU 50.

The keyboard 62 is used for inputting and modifying search information, and also for specifying the position of the search information recorded in the filing device 61, especially maps and place names. It is connected. The voice input unit 64 is used to input voice when registering voice for search, and the speaker data EPROM 65 is used to encode the input voice at the time of voice registration and record it as registered voice.

In addition, the audio data memory 66 is connected to the memory card I/F 51.
It temporarily stores the audio recorded on the memory card 26 that is input via the OA converter 67.
, and is guided to a speaker 69 via an amplifier 68 and reproduced as audio. The speaker recognition unit 70 recognizes the voice data input via the memory card I/F 51 and the E2PRO for the speaker data.
This is to determine whose voice the voice is by comparing it with speaker data registered in the M65. The judgment result for this speaker is CP
It is also output to U50 and used as an index during a search.

Note that 71 to 73 are printers, facsimile machines, and video telephones for transmitting and outputting stored images and search images.

In the above configuration, next, the processing on the playback machine side is shown in Figures 6 to 2.
This will be explained using the flowchart shown in FIG.

First, the images on the memory card 26 are filled in according to FIG. 61 will be described below.

When the memory card 26 is inserted into the player (step #
41), the recorded images in the memory card 26 are sequentially read out (step #42). The read recorded image is played back for multi-screen use in special playback processing l552, and then
Multi-display is performed on the V monitor 57 (step #43).

Multi-display is performed by allocating a predetermined number of frames to one frame, or a number of frames set according to the number of recorded images in the memory card 26.

Next, the CPU 50 accepts the selection of an image desired to be registered in the filling device 61 from among the images in the multi-screen,
Next, when the frame number of the relevant image is input using the keyboard 62 or the like to select it (step #44), the multi-image display is performed again for the selected image (
Step #45). Next, in step #45, it is determined whether the search information input on the camera side is to be modified or added. Examples of such corrections and additions include correcting a person's name when the result of speaker identification is displayed incorrectly, correcting position information, and adding comments.

If there is no modification of the search information, press N at step #46.
o> By performing a registration operation using the keyboard 62, the image and search information are recorded in the 7 filling device 161, and the recorded image and search information are erased from the memory card 26 (step #47). , step #48). This erasing operation creates a free space in the memory card 26, making it possible to record new captured images.

On the other hand, if there is a correction etc. (YES in step #46),
When an image that requires correction or the like is selected using the keyboard 62 or position indicating member 63, the image and search information are displayed on the TV monitor screen (step #49, step #5).
0). The user makes necessary corrections and additions while looking at the screen (step #51). Every time the correction, etc. of one image is completed, the other images are asked whether or not correction, etc. is necessary (steps #51 to #46).
), and when the necessary corrections, etc. are completed, the process moves to step #47 and the registration process ends.

Next, the procedure for registering audio will be explained with reference to FIGS. 7 and 8.

Figure 7 shows “Voice Registration
'', and FIG. 8 shows the procedure of ``audio registration ■'' in which only audio is registered. This amphipod is in step #51 above.
It may be executed in , or it may be provided as a separate voice registration mode.

In FIG. 7, first, after the CPU 50 enables reception of voice input, voice is input from the microphone of the voice input unit 64 (step #61), and the input voice is transmitted to the AD.
It is converted and encoded (steps #62, #63).

This encoded voice data is used for recording speaker data.
It is registered in the PROM 65 (step #64). Next, the CPU 50 makes it possible to accept data from the keyboard 62, and when the speaker's name is input from the keyboard 62 (step #65), it is encoded (step #66).
, and is further associated with the voice data of the speaker and E2PR.
It is registered in OM65 (step #67).

Therefore, as will be described later, when searching by voice, the speaker's name is superimposed on the TV monitor 57 along with the search image by superimposition.

In FIG. 8, first, the CPU 50 makes it possible to accept voice input, and then the voice input cuff! ! When audio is input from the microphone 64 (step #71), the input audio is AD converted and encoded (steps #72 and #7).
3). This encoded voice data is registered in the E2 PROM 65 for recording speaker data (step #74).

Therefore, only the searched image will be displayed on the TV monitor 57 when searching by voice.

Next, various search procedures will be explained with reference to FIGS. 9 to 21.

FIG. 9 shows the main flow of the search process.

First, select which item (condition) to search using the keyboard 62.
etc., the CPU 50 collates the search item with each self-portrait or search information (step #81), sequentially reads matching images from the memory card 26, and displays them on the TV monitor 57 in multiple formats (step #82). . Then, the user selects the desired one from among the multi-displayed images.
Or multiple images are selected (step #83)
.

When the selection for the current display screen is completed, it is determined whether all other multi-screens that display images that match the search items have been displayed (step #84), and if there are other multi-screens, the current screen is will be updated to the next screen (step #
85). Then, when the image selection for the multi-screen to be updated is completed, Y is selected in step #83 and step #84.
ES), the selected image is output in a desired output format as described below (step #86).

FIG. 10 shows a 70-chart of "item search" for the search items shown in step #81.

In this example, the search items are "location", "1 date and time", "
Examples include weather, people's names, indoors and outdoors, scenes of people, events, and audio.

When “Item Search” starts, first, “
An inquiry is made as to whether or not to select "location" (step #91). If "location" is selected, the "location search" flow shown in FIG. 11 is executed (step #92).

When "Date and time" is selected, "Date and time search" shown in Figure 12
The flow is executed (step #94).

If it is not selected, then an inquiry is made as to whether or not to select "weather" as a search item (step #95).
. When "weather" is selected, the "weather search" flow shown in FIG. 13 is executed (step #96). If it is not selected, then an inquiry is made as to whether or not to select "person's name" as a search item (step #97). When "person's name" is selected, the flow of "person's name search" shown in FIG. 14 is executed (step #98). If it is not selected, then an inquiry is made as to whether or not to select "indoor/outdoor" as a search item (step #99).If "indoor/outdoor" is selected, "indoor/outdoor search" shown in FIG. 16 is performed. flow is executed (step #100), if not selected,

When "event" is selected, the "event search" flow shown in FIG. 19 is executed (step #104). If it is not selected, then an inquiry is made as to whether or not to select "audio" as a search item (step #105).
.

When “Voice” is selected, “Voice search” shown in Figure 20
The flow is executed (step #106). continue,
Re-selection is made possible in consideration of changes or additions to search items (NO in step #107). Thereafter, the "item search" process is ended and the process returns to step #82.

These search items depend on each sensor on the camera side, and it is also possible to select two or more items at the same time.

The details of each of the above search processes will be explained below with reference to FIGS. 11 to 21.

In the flow of "location search J" shown in FIG. 11, the location code and/or GPS positioning data serve as an index of location information.

First, it is determined whether or not to display a map on the TV monitor 57 (step #111). When displaying a map, that is, when indicating a location on the map, the filing device 6

The indicated position data (latitude, longitude) is calculated based on the displayed map and the output position signal of the position pointing member 63. Alternatively, the detection may be performed using a tablet or the like, for example. On the other hand, if map display is not required, place names and places recorded in association with recorded images are read out and displayed.
A desired place name, etc. is input from the displayed place names, etc. from the keyboard 62 to specify it (step #11).
4, #115). Subsequently, the CPU 50 searches for an image matching the specified position or input place name, etc. (step #116). This search is performed by scanning search information recorded in association with each image. When the search is completed, the number of matching items is displayed as the search result (step #117). At this time, the frame number of the corresponding image may be displayed. After this,
It is determined whether re-search is necessary (step #118)
. Examples of re-search include a case where the number of matching items is large or, conversely, a case where the number of matching items is zero. In the case of re-search, if you input or specify other search conditions, the search by CPLI 50 is performed in the same manner as above (step #111 to step #1).
17). Then, when the search ends, step #118
If No>, return to step #93.

In the flow of "date and time search" shown in FIG. 12, the date information from the timer 24 serves as an index.

When the date and time, that is, the year, month, day, hour, minute, season, etc., are input from the keyboard 62 (step #121), the CP
The LI 50 searches for images matching the input search conditions (step #122). This search is performed by scanning the search information (date and time data) recorded in association with each image, as described above. In addition, CPU50
There is a storage means in which the season and date and time data are associated with each other, and when the search condition is season, the input season is converted into the corresponding date and time data in the storage means, and the converted Search is performed using date and time data.

When the search is completed, the number of matching items is displayed as the search result (step #123>. Note that the frame number of the matching image may also be displayed as described above. After this, the search is performed again. It is determined whether or not the search is necessary (step a124).In the case of a re-search, if other search conditions are input, a search is performed using the CPLI 50 in the same manner as above (steps #121 to #123). When finished (No in step #124), the process returns to step #95.

In the flow of "weather search" shown in FIG. 13, the temperature and humidity information from the temperature sensor 17 and humidity sensor 18 serve as indexes.

Weather-related conditions, such as "sunny", "rainy", "hot"
, "It's cold", etc. are input from the keyboard 62 (step #131), the CPU 50 searches for images matching the input search conditions by scanning the search information (step #132). The CPU 50 is provided with a storage means that stores in advance the correspondence between the above-mentioned weather-related conditions and weather data consisting of temperature and humidity. For example, if you enter "hot", you may search based on a certain temperature or humidity, such as a temperature of 30° C. or higher or a humidity of 80% or higher. Furthermore, the reference temperature and humidity may be changed depending on the location, date and time (and season). For example, if you want to search for "summer + hot", the temperature is 30℃ or higher, and 7.8.9
On the other hand, for "winter + hot", the temperature should be 25 degrees Celsius or higher, and it should be from December, January, and February. When searching, the input weather-related conditions are converted into corresponding weather data in the storage means, and the search is performed using the converted weather data.

When the search is completed, the number of matching items etc. are displayed as the search results (step #133). Thereafter, it is determined whether a re-search is necessary (step #134). If you want to search again, enter other search conditions and the CPI
A search using J50 is performed (steps #131 to #133).

Then, when the search is completed (NO in step #134)
, return to step #97.

In the flow of "person name search" shown in FIG. 14, "voice" or "person name" serves as an index.

When a "person's name" is input from the keyboard 62 (step #141), the CPU 50 searches for images matching the input search conditions (step #142). This process is performed according to the "search process" shown in FIG.

That is, first, it is determined whether the search is by "voice" or by "person's name" (step #151). In the case of a search by "voice", the input person's name is encoded and converted into a person's name code, and the voice code corresponding to the person's name code is extracted from the E2PROM 65 (step #153).
, #154). Next, the audio data recorded in association with the pre-registered image is extracted from the filing device 61 and encoded (step #155,
#156).

Then, the audio code from the EPROM 65 is compared with the audio code from the 7 filling device W61 (
Step #157). This verification is done by the filing device 61.
This is performed for all images by sequentially scanning the audio codes of the images registered in the image (No in steps #156 to #158, loop of step #159).

When the matching for all images is completed (YES in step #158), the process returns to step #143. On the other hand, if the search by person's name is selected in step #151, the search is performed by scanning the person's name code input at the time of image registration to the filing device f61 (step #152), and when the search is completed, step #143 Return to.

Returning to FIG. 14, the number of matching items etc. are displayed as the search results (step #143), after which.

It is determined whether re-search is necessary (step #144)
. In the case of re-search, if other search conditions are input, the search by the CPU 50 is performed in the same manner as above (step #
141 to step #143).

Then, when the search is completed (No in step #144)
, return to step #99.

In 70- of "indoor/outdoor search" shown in FIG.
The output from the B sensor 14 becomes an index.

When either "indoors" or "outdoors" is selectively input from the keyboard 62 (step #161), the CPU 50 searches for images that match the input search conditions by scanning the search information ( Step #162). C
PL, 150 contains the correspondence between the above search conditions and the output of the WB sensor (color density data), for example, "indoor" for color temperature data corresponding to fluorescent lighting, and "indoor" for color temperature data corresponding to sunlight. A storage means is provided for storing temperature data as "outdoors". When searching, one of the input "indoors" and "outdoors" is converted into corresponding color density data in the storage means, and the search is performed using the converted color temperature data.

When the search is completed, the number of matching items etc. are displayed as the search results (step #163). After this, it is determined whether a re-search is necessary (step #164). If you want to search again, enter other search conditions and the CPU
50 is performed (step #161 to step #163).

Then, when the search is completed (No in step #164)
, return to step #101.

In the flow of “person scene search” shown in Figure 17,
The information on the F focal path JIlfJ and the object distance DJ (image magnification β-f-D) serves as an index.

First, select either "person" or "landscape" on the keyboard 62.
(step #171), the CPU 50 executes a search for images matching the input search conditions (step #171).
Step #172). This process is performed according to "Search Process ■" shown in FIG. That is, first, all focal lengths f and subject distances recorded in correspondence with images registered in advance in the filing device 61 are read out, and each image magnification β-f-D for all images is calculated ( Step $181>.Subsequently, each obtained image magnification β is β≧1/
100 or not (step #182), β≧1
/100, it is considered a landscape Step #1
84), and in the opposite case, it is determined that it is a person (step 1).
183), and CPL 150 extracts the result of step #183 when "person" is input as a search condition, and extracts the result of step #1 when "landscape" is input as a search condition.
Extract 84 results.

Note that as a matching method, discrimination may be performed for each image as described above, and such discrimination may be sequentially repeated.

When the determination for all images is completed, the process returns to step #173.

Returning to FIG. 17, the number of matching items etc. are displayed as the search results (step #173). Thereafter, it is determined whether a re-search is necessary (step #174). If you want to search again, enter the other search condition, and click C in the same way as above.
A search is performed by the PU 50 (step group 1 F1 to step #173). When the search is completed (No in step #174), the process returns to step #103.

In addition, in the above embodiment, the image magnification β, "person", "landscape"
Although the association is stored as a program, a storage means may be provided in the CPU 50 in which the image magnification β and "person" and "landscape" are stored in association with each other in advance. In addition, as another search method, the image magnification β is calculated from the recorded focal length f and subject distance;
The range of image magnification β for person j and “landscape” may be determined in advance, and the search may be performed by determining in which range each image magnification β to be searched is included.

In the “event search” flow shown in Figure 19,
The location code (event code) becomes the index.

When an event name is input from the keyboard 62 (step #191), the CPU 50 searches for an image matching the input search condition by scanning the event code recorded in association with the image registered in advance in the filing 1i1F 61. (Step #192). When the search is completed, the number of matching items etc. are displayed as the search results (step #193). Thereafter, it is determined whether a re-search is necessary (step #194). In the case of re-search, if other search conditions are input, the search by the CPU 50 is performed in the same manner as above (steps #191 to #1).
93). Then, when the search is completed (step #194
If No>, return to step #105.

In addition, if the location code is an identification code for the location or a JIs code string of characters that displays information about the location, it will be possible to search directly using the code, and the content of the location code will be recorded as is when shooting without having to distinguish it. It becomes possible to do so. Furthermore, since no special determining means is required to determine the content of the location code, the configuration of the search side, for example, can be simplified accordingly.

In the flow of "voice search" shown in FIG. 20, the voice recorded in association with the image is compared with the voice input during the search.

When a voice is input from the microphone of the voice input section 64 (step #201), a search for an image matching the voice within the CPU 50 is executed (step #192). -This process is performed according to "Search process ■" shown in FIG. That is, first, the input voice is AD converted, encoded, and stored in a reference section (not shown) (step #21).
1 to step #213). Next, the filing device 61
Audio data recorded in association with images registered in advance is extracted and encoded (steps #214, #215). and.

The audio code from the reference section is compared with the audio code from the filing device 61 (step #216).
>. This verification is performed for all images by sequentially scanning the audio codes of the images registered in the filing device 61 (No in steps #215 to #217, loop of step #218). When the verification of all images is completed (YES in step #217), the process returns to step #203.

Returning to FIG. 20, the number of matching items is displayed as the above search result (Step #203>. After this, it is determined whether a re-search is necessary (Step #204). In the case of a re-search, it is determined whether the re-search is necessary or not. When the word is input, a search is performed by the CPU 50 in the same manner as above (step #201).
~Step #203). Then, when the search is completed, the result in step #204 is No>, and the process returns to step #107.

Next, returning to FIG. 9, the execution process of step #86 will be explained using FIG. 22.

In this execution mode, first, the output format is selected. Table 1 shows this output format.

(Hereinafter, blank space) Table 1 In other words, after the search is completed, one output format is selected from the output formats A to F in Table 1 above, and the keyboard 6
2, for example, when a corresponding character is input (step #221), the number of output images that are the search results is set to N (step #222), and then the images to be output are 7 filled in order of decreasing frame number. are read out from the frame memory 53 and sequentially transferred to the frame memory 53 (step #2
23>. Next, the image is output according to the output format selected in step #221. Output type! ! If A is selected (YES in step #224), the image will be displayed on the TV monitor 57. If output type IIB is selected (YES in step #225), the focal length f and subject distance of the image will be displayed on the TV monitor 57. Data regarding the size of the subject on the imaging plane, that is, the scale size, is determined from the information, and the image and the scale size are combined (steps #226, #22
7>.

That is, the scale size is superimposed with the image in the composition section 54 and output to the TV monitor 57.

For example, when displaying a unit scale (see Fig. 24 (B)), the scale size marked on the unit scale SC is the length per unit scale calculated from the focal path 1111f and the image magnification β calculated from the subject distance. is calculated.

Here, regarding the calculation of the length of the unit scale SC,
This will be explained in detail using the principle diagram in the imaging state shown in FIG.

In the figure, L&;tll is the distance from the subject 100 to the imaging plane 200, f is the focal length of the photographic lens 300,
H is the distance between the principal points of the photographic lens 300, X is the distance from the subject 100 to the front focal point of the photographic lens 300, and X- is ms
The distance from the screen 00 to the rear focal point of the photographic lens 300,
y is the length of the subject 100, y- is the length of the image of the subject 100 on the ** plane 200, and each of the above variables 1. 'r, H
, x, xy, y-, y:y-quakex:f-f:x-...(1)x
-L-2f-H-x ---------(2) is the relationship. From these equations (1) and (2),
-2f-H)x+f2-0- The equation (3) holds true. Finding the root of this equation (3), x-((L-2f-H)+ -H) -4f )/2... (4) Furthermore, using equation (2) above, , x = -((L-2f-H) - -1-1) -4f )/2 (5). Also, from the above formula (1), y−y−・X/f ・・・・・・(
6) y−y=・f/x−・・・・・(7) Therefore, based on x and x− in the above formulas <4) and <5), this formula (6) or (7) By performing the calculation, the length y of the subject corresponding to the negative length y' on the imaging plane can be found. Here, if the length y' of the image on the imaging surface is treated as the length of the unit scale SC, then this unit scale is (I
Since its actual length (on the image plane) is known in advance, the unit scale S can be calculated by the above equation (6) or (7).
The scale size of C is found.

FIG. 24 shows an example of displaying the scale size.

4A is a display example in which the image magnification is displayed as is, and FIG. 2B is a display example in which the unit scale SC corresponds to 10 cm.

By displaying such a scale size, the actual size of the image can be easily grasped. Furthermore, since the display timing of the scale SC can be freely changed by the readout clock generator 59 controlled by the CPU 50, the scale SC can be moved to a desired position using, for example, a trackball (position specifying member 63). If you can do this, it will be easier to operate.

Furthermore, it is easy to turn on and off the scale display, and the display formats shown in FIGS. 3A and 3B may be freely switched.

In addition, by using the technique described in JP-A-58-158507 to imprint the scale onto the silver halide film, it is possible to make the display of the scale size applicable to the silver halide film as well. I can do it.

Next, the output form! If IC is selected (step #22
8), the size of the display screen (for example, CRT inches, etc.) is input from the keyboard 62 (step #8).
229>. Subsequently, the image size is changed based on the image magnification determined from the focal length f and the subject distance and the display screen size (step #230). That is, the actual size of the subject finally displayed on the TV monitor 57! The display magnification of the size of iI (ii) is displayed at one size, or the size of the display image is changed and displayed so that the display magnification is fixed at a predetermined size regardless of the display screen size.

That is, the CPU 50 has a display magnification calculation means that calculates the display magnification of the reproduced image from the image magnification determined from the focal length f and the subject distance and the display screen size. The size of the image displayed on the TV monitor 57 with respect to the size of is determined. In addition, if the display magnification is set in advance, the ratio between the display magnification calculated by the display magnification calculating means and the set magnification is calculated, and the displayed image is enlarged or reduced according to this ratio. Image processing is performed as necessary.

In the above, the final display magnification is displayed at an appropriate location on the TV monitor 57 as necessary.

By doing so, it is possible to easily grasp the actual size of the image displayed on the TV monitor 57.

Next, the output form! If LD is selected (step #23
1: YES), the image to be displayed in a composite manner is extracted by the item search shown in FIG. #233).Subsequently, the image magnification of the first selected image, the image magnification of the second selected image, and both images to be displayed together are led to the special reproduction processing unit 52, where, for example, The image size is appropriately changed so that the specific subject is the same size, one is stored in the image frame memory 53, and the image is output to the TV monitor 57 (step #2
34). By doing so, the sizes of the objects in both images finally displayed together on the TV monitor 57 can be displayed as if they were the same size. Alternatively, if the image sizes of both images that are displayed together are made to match, the actual size of the subject in both images can be easily compared. Furthermore, as in the case of scale display, by moving (weighting) both display images with a trackball (position specifying member 63) or the like, a composite photograph or the like can be enjoyed.

Note that it is also possible to combine the current photographed image and a previously photographed photograph by using both image magnifications, so that, for example, an out-of-print photograph can be reproduced as a completed photograph.

Next, if output form E is selected (step #235
(Yes), the displayed image is guided to the special reproduction processing section 52, where various special processing such as mosaic, negative/positive inversion, etc. are applied to the displayed image, and then output to the TV monitor 57 ( Step #236).

Next, if output form F is selected (step #235
7-No>, a predetermined number of images, such as 4 images, 9 images, 16 images, etc., are reproduced on one screen. This predetermined number of sheets is selected in advance or as necessary, and (2×3)
It may also be possible to select a desired number of sheets, such as .

First, the frame number and number of images for which multiple reproduction is desired are stored (step #237).

Next, it is determined whether the number of images has reached the predetermined number (step #238), and if it is the predetermined number, multi-processing is performed (step #239), and step #24
Transition to 0. On the other hand, if the number of sheets is not the predetermined number, step #
247. Note that details of the processing in the case of output form F will be described later.

Now, when one of the output formats A to F is selected and the image obtained under the selection is displayed on the TV monitor 57 (step #240), it is next determined whether audio is recorded for the displayed image. A determination is made as to whether or not (step #24
1). If audio is recorded, the audio corresponding to the displayed image is played back (step #242). Subsequently, it is determined whether the displayed image is to be printed or transmitted (steps #243 and #245). When a print instruction is issued, the displayed image is printed out by the printer 71, and when a transmission instruction is issued, the fax 72
The displayed image is transmitted using the TV phone 73 or the like (steps #244 and #246).

When printing or transmission of one sheet is completed, the number of output images N set in step #221 is decremented by 1 (except when the output form IF is selected),
Next, it is determined whether the number of output images, N, is 0 (
Step #248).

If it is not N-0, the process returns to step #2''21, the next image is displayed, and after the displayed image is printed or transmitted, the value of N is decremented (steps #221 to 221).
Step #247>. This process is repeated for the number of output images, and after that, when the number of output images is N-0 (step #248
YES), output type W! Except for the case of AF (YES in step #249), the process returns to the main flow of FIG. 9.

On the other hand, when the output type MF is selected, a predetermined number of images are captured in one screen, so the output type MF!
Processing that is somewhat different from that for IA to F is performed. That is, each time an image is read out, the number of images is decremented from the output image number N (NO in step #238, step #247), and each time a predetermined number is reached (YES in step #238), multi-processing is performed. (Step #239)
. After a predetermined number of multi-processed images are displayed on the TV monitor 57, they are printed or transmitted in units of a predetermined number of images as described above. At this time, the images at the time when the predetermined number of images is reached are stored in step #247 after step #246.
By decrementing the number N, the number N of output images can be decremented accurately. In addition, output form! In the case of IF, if the number of output images N is not an integral multiple of the predetermined number, even if it becomes N-0 in step #248, there are remaining images (N in step #238).
o, YES in step #248, N in step #249
o>, the processing from step #240 onward is also performed on the remaining images.

FIG. 25 shows an example of the table of contents displayed. When the memory card 26 is inserted into the playback device, the "Date and Time", "Time", and "Location" are displayed in the order of recording (or in the order of the photographed frame numbers) as shown in the figure.
Contents such as “audio presence/absence” and “person’s name” are displayed on the TV monitor 57.
will be displayed. Based on this table of contents display, it becomes easy to select the method for reproducing and displaying images or recording them in the filing device 61.

FIG. 26 shows an example of a screen for inputting search conditions for a search. Search conditions include "date and time,""time," and "location."
"Speaker", "Weather", and "Other" are prepared.
As shown in the figure, in each condition column, "summer" is entered as "date,""evening" is entered as "time,""time of death" is entered as "place," and "Namba" is entered as "speaker" from the keyboard 62. There is. The CPU 50 executes the above-described search process based on the input search conditions. On the other hand, various operation instruction columns are prepared at the bottom of the screen, and can be specified by pointing the position with a tablet or mouse, for example.

FIG. 27 shows an example of the memory map of the memory card 26, which consists of a search information area, an image data area, an audio on/off and audio data area. Also,
In this search information area, start addresses (■Sta, Asta) and end addresses (Vend, Aend) for each of the above areas are also written. Recording in each area is performed in the order of image data, audio data, and search information according to instructions from the CPtJ50.

Next, a case where each of the above-mentioned searches is performed using an inference function (fuzzy search) will be explained with reference to FIGS. 28 to 31.

With such reasoning, searches are performed based on membership functions. This membership function is stored in advance in the suitability storage means in a form corresponding to each search condition. Then, when a search condition is input, a membership function corresponding to the input search condition is selected, and a search is performed in descending order of suitability based on the selected membership function.

Now, Figure 28 shows the length and size) search, for example r 5
This shows the membership function when it is desired to reproduce something of about 0 CmJ. [For 50 cmJ, the suitability is "1", and for r25cmJ and r75cmJ, the suitability is "0".
．． 5". Therefore, if you enter the search condition r50cmJ, based on this membership function, the suitability is "1", "0.9", "0.8", etc.
The order of priority is given as follows: [50±5cmJ
are extracted and reproduced. Next, r44 crn
J, r56cmJ, followed by [4OcmJ, r60
Those near cmJ, and those with the highest degree of suitability, such as those near 35cmJ and r65cmJ, will be extracted and reproduced in order.Also, if you enter the search condition rlookmJ, rioo±5cmJ
For example, r75cmJ has a fitness of “0”.
．． 5'', and as described above, those with the highest degree of suitability are sequentially extracted and reproduced.

FIG. 29 shows membership functions when it is desired to reproduce a location search, for example, a photograph taken in the "Kinki region." Therefore, when "Kinki region" is input, the fitness level is "1" based on this membership function.
Films shot in ``Osaka'' and ``Kyoto'' are extracted and played back.

Next are those taken in "Hyogo" and "Nara", followed by "Wakayama" and "Shiga", followed by "Mie", "Tokushima", and "Okayama" and "Fukui", which have a high degree of relevance. Things will be extracted and reproduced in order.

Figure 30 shows seasonal searches, such as "spring", "summer", "autumn"
, which shows each membership function when you want to play back images taken during each season of "winter." for example,"
If you want to play back images taken in ``Spring,'' first set the suitability to ``1.''
” photos taken in “April” and “May j” are extracted,
will be played. Next, images taken in "June" will be extracted and played back. Furthermore, when it is desired to playback images taken in "summer", images taken in "July", "August", and "September" with a suitability of "1" are extracted and played back. Next, images taken in "June" will be extracted and played back. If you want to play back images taken in "autumn," images shot in "October" and "November" with a suitability of "1" are extracted and played back. Next, images taken in September j will be extracted and played back.If you want to play back images taken in winter, select
Photographs taken in December J "January" and "February" are extracted and played back. Next, images taken in "March" will be extracted and played back.

Note that the seasonal search is not limited to monthly units as described above, but may also be performed by date units. For example, for "mid-September," the suitability for "summer" may be "0°5" and the suitability for "autumn J" may be "0.5." , temperature, humidity, etc., to perform a search from a broader perspective.For example, when the search condition is "summer + traffic sign", the search condition that satisfies the above-mentioned "summer" may be searched from a broader perspective. Take the logical AND of the temperature that is above 30℃ and the temperature that is above 30℃. Similarly, when the search condition is "100% hot in winter", a logical AND is performed between those that satisfy the above-mentioned "winter" and those that have a temperature of 25° C. or higher.

FIG. 31 shows the membership function when it is desired to play back images taken in each time zone such as "Nflj, r noon", "evening", and "night" in the date and time search.

If you enter "morning", first "6 o'clock" with a fitness of "1" is input.
The images taken between "9 o'clock" and "9 o'clock" are extracted and played back. Subsequently, images taken in the order of "5 o'clock,""10o'clock," and "4 o'clock" are extracted and played back. If you enter "daytime", firstly, "12 o'clock J to "14 o'clock J" with relevance "1".
What was photographed in the Garden of Time will be extracted and played back. Subsequently, "11 o'clock", r 1511J, 2Wlile Sale tC mo(1) is extracted and played back. When "evening j" is input, first, images taken at "17:00" and "18:00" with a suitability of "1" are extracted and played back. continue,
The image taken at "16 o'clock" is extracted and played back.

When "night" is input, first, images taken in the garden between "8:00 p.m." and "3:00 p.m." with a suitability of "1" are extracted and played back. Subsequently, the image taken at r41J at "7pm" is extracted and played back. Note that, as in the case of the seasonal search, search conditions such as temperature, humidity, etc. may be taken into account to perform a search from a broader perspective.

In addition to the above search examples, the barometric pressure sensor 19 and GP
It is also possible to search for images taken during mountain climbing from the altitude information provided by the S receiver 23. Furthermore, by adding the focal length f and photographing distance to the atmospheric pressure information and altitude information, it is possible to automatically input photographing information as an aerial photograph.

Further, the following can be considered as other determination methods at the time of search. That is, (1) Distinguish between men and women using voice recognition technology based on the difference in sound quality between men and women.

(2> Person identification is performed based on the color temperature and pattern recognition of the photographed image of the WB sensor 14.

(3) Adults and children are distinguished from image magnification and pattern recognition.

(4) The presence or absence of glasses is determined by pattern recognition I.

(5) The person in the image is memorized in advance, and the person in other images is discriminated using pattern recognition and the school function.

In this embodiment, a digital memory is used as the recording medium, but an analog memory such as a floppy disk may also be used. Further, although the camera and the playback device are separate bodies, they may be integrated. Furthermore, the data obtained from each sensor may be displayed on the operation and display section 25 or on a separately provided display section.

Furthermore, although this embodiment has been explained using an electronic still camera, each sensor is provided in a silver halide camera, and the photographing information of each of the above sensors is imprinted at an appropriate location within the photographic screen using a well-known date imprinting technique. Good too. In this case, the playback machine includes an optical reading section, a film drive section, a memory, a search processing section according to this embodiment, etc., and the film container is set in the optical reading section and the frames are sequentially or instructed. The photographed image and the imprinted photographic information may be read by COD or the like, extracted as an electrical signal, and recorded in the memory. Then, the same search process as described above is executed using the captured image and the captured information.

〔Effect of the invention〕

As explained above, according to the photographed image recording and reproducing system according to the present invention, there is provided a camera that records a photographed image, focal length information, and subject distance information in association with a recording medium, and a photographic image recorded on the recording medium. It consists of a player that plays back images, and the player automatically displays data related to the size of the subject based on the focal length information and object distance information corresponding to the image being played back. In this way, the actual size of the subject can be easily determined from the reproduced image without being forced to perform the frequent work of placing something corresponding to the scale on the object's scale each time.

In addition, multiple displays M! are displayed as data regarding the size of the subject. ! In addition to adopting this, we also made it possible to switch selectively.
You can select an easy-to-recognize display of 8m, and more accurately and quickly determine the size of the subject. It becomes possible to do this.
