BACKGROUND OF THE INVENTION
The present invention relates to a photographing apparatus that photographs an upper surface of a subject placed in a case using a mirror placed above the subject, and a storage medium that stores a control program thereof.
[0002]
[Prior art]
In order to shoot a plurality of subjects with the same shooting conditions as possible, it is convenient to continuously shoot using the same background. In particular, when a large number of relatively small subjects are to be photographed, it is possible to efficiently photograph by using a case that accommodates the subject and setting the subject in this case and sequentially photographing.
[0003]
Furthermore, if a mirror is installed above the subject and the image reflected in the mirror is taken with the camera, the front and top surfaces of the subject can be taken without moving the subject and without moving the camera greatly. Can be efficient.
[0004]
[Problems to be solved by the invention]
However, when an image of the upper surface of the subject reflected in the mirror is captured, the captured image is a mirror image of the subject, and therefore it is necessary to perform image processing that reverses the captured image in order to obtain a captured image at the normal position. . This processing is performed by the user switching the setting state when executing an application program that mainly performs image processing.
[0005]
However, after taking a picture of the top surface of the subject in a setting state in which the photographed image is reversed, it is easy to make a mistake when photographing the front surface of the next subject in a state in which the photographed image is set to be reversed. There was a problem.
In other words, the user who is shooting is confused as to whether or not the shot image is set to be reversed, and the image in front of the subject that is not a mirror image is saved in a reversed state, or the shot image to be reversed Sometimes saved without flipping. Depending on the design of the subject, it may be difficult to determine if the left and right sides are mistakenly flipped at first glance, and it will be very time consuming to perform image processing and shooting again after a series of shots have been taken. There was a problem that the progress of work was hindered.
[0006]
In order to solve the above-described problems, the present invention provides an imaging device that can reliably prevent mistakes that confuse setting states when shooting is performed by alternately switching between a setting state in which a captured image is reversed and a normal setting state. The purpose is to provide.
[0007]
[Means for Solving the Problems]
In order to solve the above problem, the invention according to claim 1
An imaging device that captures an image of an object to be photographed with a camera that can move and rotate in a predetermined direction, and displays the photographed image on a display means,
A mirror for projecting the image to be imaged onto the imaging surface of the camera;
Determining means for determining whether or not this mirror is included in the imaging range of the camera based on the angle of the imaging surface of the camera;
Display control means for displaying on the display means an inverted image obtained by inverting the top or bottom or the left and right of the image captured by the camera when the determination means determines that the imaging range of the camera includes the mirror;
It is characterized by having.
[0008]
According to the first aspect of the present invention, in a photographing apparatus for photographing a photographing object with a camera that can be moved and rotated in a predetermined direction and displaying the photographed image on the display means, the image of the photographing object is displayed on the camera by the mirror. Projecting on the imaging surface, it is determined whether or not this mirror is included in the imaging range of the camera based on the angle of the imaging surface of the camera by the determining means, and it is determined that the imaging range of the camera includes the mirror In this case, the display control means displays on the display means an inverted image obtained by inverting the top and bottom or the left and right of the captured image of the camera.
[0009]
Therefore, when taking an image of the object to be photographed reflected in the mirror with the camera, it is detected that the image reflected in the mirror is photographed according to the angle of the imaging surface of the camera, and the photographed image is inverted and displayed. When the image is moved and rotated, an image in which the mirror image is inverted is displayed without performing a setting for inverting the captured image. As a result, when shooting using a mirror, the captured image is inverted and the image at the normal position is displayed, and when the image of the subject is captured without using the mirror, the captured image is displayed as it is, The displayed image is always the image at the normal position. Therefore, there is no mistake such as reversing the shot image that does not need to be reversed accidentally. Can be improved.

FIG. 5 is a diagram showing the relationship between the tilt of the camera tilt base 403 and the hood 402 and the detection operation of the angle sensor 403b and the angle sensor 407b. FIG. 5A shows the tilt of the camera tilt base 403 and the detection operation of the angle sensor 403b. (B) shows the relationship between the hood 402 and the detection operation of the angle sensor 407b.
[0046]
As shown in FIG. 5A, the angle sensor 403b is attached to the rotation axis of the camera tilt base 403 or the vicinity thereof. The angle sensor 403b detects the tilt of the camera tilt table 403 with reference to a predetermined angle when the camera tilt table 403 rotates about the rotation axis, and the tilt angle indicating the detection result. This is a sensor that outputs a detection signal (voltage signal) to the I / F 301 at any time.
For example, in the state shown in FIG. 5A, the angle sensor 403b sets the camera tilt table 403 in the direction in which the imaging surface of the digital camera 20 faces upward, assuming that the camera tilt table 403 is in a horizontal state “± 0 °”. A tilt angle detection signal indicating “+ P °” is output when tilted by P degrees, and when the camera tilt base 403 is tilted by Q degrees in a direction in which the imaging surface of the digital camera 20 faces downward, “−Q ° ”Is output.
[0047]
In addition, as shown in FIG. 5B, the angle sensor 407 b is attached in the vicinity of the rotation axis of the hood 402. The angle sensor 407b detects the rotational position of the hood 402 that is driven and controlled by the motor 407a with reference to a predetermined angle, and outputs a rotational angle detection signal (voltage signal) to the I / F 301 as needed.
For example, in the state shown in FIG. 5B, the angle sensor 407 b indicates that the state where the hood 402 is horizontal is “± 0 °”, and the hood 402 is inclined by R degrees in the direction in which the imaging surface of the digital camera 20 faces downward. If the hood 402 is tilted by S degrees in the direction in which the imaging surface of the digital camera 20 faces upward, the rotation angle detection indicating “+ S °” is output. Output a signal.
[0048]
Therefore, as shown in FIG. 5, by calculating the sum of the angle detected by the angle sensor 403b and the angle detected by the angle sensor 407b, the inclination of the imaging surface of the digital camera 20 with respect to the horizontal plane can be calculated. it can.
[0049]
Next, the operation of the present embodiment will be described.
First, the operation of each part in the photographing apparatus 40 will be described with reference to the cross-sectional views of the photographing apparatus 40 shown in FIGS.
[0050]
In the photographing apparatus 40 shown in FIG. 6, a lighting device 408 is attached to the upper left portion of the case 401 in the drawing, and irradiates light on a subject placed on a subject base 405 in the lower right portion. The illumination intensity of the illumination device 408 is controlled by the illumination control unit 307 in the imaging control device 300. In addition, a mirror 409 is attached to a door 410 that can be opened and closed in the upper right portion of the case 401 in the drawing, and the upper surface of the subject (product) placed on the subject base 405 using the mirror 409 is attached to the digital camera 20. Project onto the imaging surface. Further, the door 410 to which the mirror 409 is attached can perform maintenance or the like of the mirror 409 in an open state.
[0051]
On the other hand, a background plate 411 is installed on the right side of the subject base 405 in the figure, and a background sheet 413 is locked to the upper end portion of the background plate 411 by a clip 412. The background color of the subject (product) placed on the subject base 405 is unified to form a good shooting environment. Further, a back door 401a that can be opened and closed is provided on the right side of the background plate 411 in the drawing, so that the background plate 411 and the background sheet 413 can be replaced.
[0052]
As shown in FIG. 7A, when photographing the front surface of a short subject (product), the hood 402 has its rotation axis as a center and the opening facing the case 401 faces upward in the figure. It is rotated so that the imaging range for a short subject is widened and adjusted to the “hood DOWN” state. In addition, the tilt angle of the camera tilt base 403 is adjusted to the “camera DOWN” state so that the imaging surface of the digital camera 20 faces downward, and the lift position of the subject base 405 is adjusted to be higher, so that the digital camera The 20 imaging surfaces are adjusted so that it is easy to capture the front of a short subject.
[0053]
Further, as shown in FIG. 7B, when the upper surface of the subject (product) is photographed, the rotation angle of the hood 402 and the height of the subject base 405 are not moved, and only the tilt angle of the camera tilt base 403 is obtained. By adjusting to the “camera UP” state, the image pickup surface of the digital camera 20 is adjusted so as to capture the upper surface of the subject projected on the mirror 409. Depending on the size of the subject 60, the hood 402 may be rotated in a direction in which the imaging surface of the digital camera 20 faces upward to enter the “hood DOWN” state. Furthermore, since the photographed image taken here is a mirror image reflected on the mirror 409, the front and back of the top surface of the subject are reversed, and the image at the normal position on the top surface of the subject is reversed by reversing the top and bottom of the photographed image after photographing. Can be obtained.
[0054]
Further, as shown in FIG. 7C, when photographing the front of a tall subject (product), the hood 402 is rotated around the rotation axis, and the opening facing the case 401 is illustrated. It is adjusted to the “hood UP” state so as to ensure an imaging range for a tall subject facing in the middle and downward direction. Further, the tilt angle of the camera tilt table 403 is adjusted so that the image pickup surface of the digital camera 20 faces downward to be in the “camera UP” state, and further, the lift position of the subject base 405 is adjusted to be low. The imaging surface of the digital camera 20 is adjusted so that it is easy to photograph the front surface of a tall subject.
[0055]
As described above, in the imaging device 40, the rotation angle of the hood 402, the tilt angle of the camera tilt base 403, and the ascending / descending position of the subject base 405 are appropriate depending on the height of the subject and the imaging conditions such as the imaging surface. Therefore, the optimum shooting environment can be easily set.
[0056]
Next, photographing processing executed by the CPU 101 in the image processing apparatus 10 in order to set each photographing condition as described above will be described based on a flowchart shown in FIG.
[0057]
In FIG. 8, first, the CPU 101 determines whether or not an “image editing” process has been instructed by an instruction operation on the input device 102 (step S101). If an “image editing” process has been instructed, the CPU 101 proceeds to step S102. If “image editing” processing is not instructed and “image editing” processing is not instructed, it is determined whether or not “automatic image capturing” processing has been instructed (step S103).
[0058]
If the “manual shooting” process is instructed in step S103, the process proceeds to step S109. If the “automatic shooting” process is instructed, the process is stored as a shooting condition specifying screen for specifying the shooting condition. A screen for designating the “imaging condition name” and the “imaging surface” stored in the imaging condition table (FIG. 4A) stored in the device 106 is displayed, and the “imaging condition name” and the “imaging” of the subject are displayed. "Face (front, top, overhead view)" is designated (steps S104 and S105), and the subject (product) is prompted to be set on the subject base 405.
[0059]
Then, when the subject is set on the subject base 405 by the user and the “shooting condition name” and the shooting plane of the subject are specified, the CPU 101 sets the shooting apparatus 40 according to each shooting condition corresponding to the specified shooting plane. Each unit is adjusted so as to meet the photographing condition (step S106).
[0060]
Thereafter, the CPU 101 executes processing for photographing the photographing surface of the subject specified in step S106 (step S107), and determines whether or not photographing completion is instructed by an instruction operation on the input device 102 (step S108). If the completion of shooting is instructed, the process is terminated as it is. If the completion of shooting is not instructed, the process returns to step S105 to execute another shooting.
[0061]
Also, when “manual operation” is instructed in step S103, the CPU 101 proceeds to step S109, executes upper surface discrimination processing described later, and manually moves / adjusts each device in the photographing apparatus 40. And the respective drive units included in the photographing apparatus 40 are moved in accordance with an instruction operation on the input device 102. Then, the CPU 101 determines whether or not the upper surface of the subject can be captured based on the position where each unit of the imaging device 40 has moved, and if it determines that the upper surface can be captured, the digital camera 20 is set to invert the captured image.
[0062]
When shooting is executed in accordance with the instruction operation of the input device 102 (step S110), it is determined whether or not shooting has been completed (step S111), and an instruction to continue shooting is input from the input device 102. Return to step S109, and if completion of all photographing is instructed, the process proceeds to step S112.
[0063]
In step S112, it is determined whether or not to store and learn data regarding the position of each part including the angles of the hood 402 and the camera tilt base 403 set in the processing of steps S109 to S111. If learning is performed here, data relating to the position of each unit is stored in the storage device 106, and the photographing conditions set in step S109 can be easily reproduced.
[0064]
Here, when an instruction to perform learning is input from the input device 102, the position of each part of the imaging device 40 and the display 12 that are temporarily stored in the RAM 103 in the top surface imaging process in step S109 are displayed. Names are given to various data indicating the setting state of the monitor screen to be stored and stored in the photographing condition table (FIG. 4A) stored in the storage device 106 (step S113), and the process is terminated.
If there is an instruction input not to perform learning in step S112, the process is terminated as it is.
[0065]
FIG. 9 is a flowchart showing in more detail the upper surface discrimination process shown in step S109 of FIG.
In this upper surface determination process, first, the CPU 101 confirms whether or not an instruction to manually move each part of the imaging device 40 is input by the input device 102 (step S121). When the manual movement is instructed, the designated device is moved to the designated position in accordance with the content of the instruction input by the input device 102 (step S122). If an instruction to manually move each unit of the imaging device 40 is not input, the process proceeds to step S131 described later without executing the subsequent processing.
[0066]
Subsequently, the CPU 101 causes the angle sensor 403b to detect the angle of the camera tilt table 403 after movement, and reads the angle of the camera tilt table 403 based on the tilt angle detection signal output from the angle sensor 403b (step S123). . Similarly, the CPU 101 reads the angle of the hood 402 based on the rotation angle detection signal output from the angle sensor 407b (step S124).
[0067]
Then, the CPU 101 calculates the sum of the angles of the camera tilt table 403 and the hood 402 read in step S123 and step S124, and determines whether this sum is larger than a predetermined “set upward angle”. (Step S125). Here, the “set upward angle” is the minimum necessary angle at which the imaging surface of the digital camera 20 should face upward when shooting the upper surface of the subject, and is set in advance and stored in the storage device 106. Yes.
If the sum of the angle of the camera tilt base 403 and the angle of the hood 402 is smaller than the “set upward angle” in this step S125, the upward state of the imaging surface of the digital camera 20 is not sufficient for photographing the upper surface of the subject. Therefore, the process proceeds to step S126, and an input as to whether to photograph the upper surface of the subject is requested. In step S126, if an instruction to specify the top surface of the subject is input from the input device 102, the display device 105 informs the user that the top surface cannot be captured by displaying on the display device 105. The process returns to step S121.
If there is no input for designating photographing of the upper surface of the subject in step S126, the process proceeds to step S131 described later.
[0068]
On the other hand, when the sum of the angle of the camera tilt base 403 and the angle of the hood 402 is larger than the “set upward angle” (step S125; Yes), the CPU 101 determines the angle of the camera tilt base 403 and the angle of the hood 402. It is determined whether or not the sum of is smaller than the “upper surface limit angle” (step S128).
[0069]
Here, the “upper limit angle” is an upper limit angle at which the imaging surface of the digital camera 20 can capture an image reflected on the mirror 409, and is preset and stored in the storage device 106. When the sum of the angle and the angle of the hood 402 is larger than the “upper limit angle”, the digital camera 20 is facing too much upward, making it impossible to photograph. Therefore, when the sum of the angle of the camera tilt table 403 and the angle of the hood 402 exceeds the “upper limit angle”, the CPU 101 indicates that the upper limit has been exceeded by displaying on the display device 105 or the like. Guidance is provided (step S129), and the process returns to step S121.
[0070]
When the sum of the angle of the camera tilt base 403 and the angle of the hood 402 is smaller than the “upper limit angle” (step S128; Yes), the CPU 101 is captured by the digital camera 20 and is displayed on the display device 105 before shooting. Thus, the subject image on the monitor screen 105a (FIG. 11) displayed on the display 12 is switched to a “mirror screen” that reverses the image reflected in the mirror and converts it into an image at the normal position (step S130).
[0071]
Then, the CPU 101 requests an input as to whether or not the shooting conditions can be confirmed in the current state (step S131), and when an input for instructing the determination is performed by the input device 102, the CPU 101 Various data such as data indicating the position of each part, data indicating whether the photographing surface of the subject is the front surface or the upper surface, and data indicating whether or not the screen is switched to the “mirror screen” are temporarily stored in the memory area in the RAM 103. (Step S132), the process ends.
If an instruction not to finalize the condition is input in step S131, the process returns to step S121.
[0072]
FIG. 10 is a diagram schematically illustrating the configuration of the RAM 103 in a state where shooting conditions are temporarily stored in the top surface shooting process illustrated in FIG. 9.
As shown in FIG. 10, in the RAM 103, “camera angle” indicated by the rotation angle detection signal output from the angle sensor 407b and “camera” indicated by the tilt angle detection signal output from the angle sensor 403b. “Angle” is stored.
Further, the “set upward angle” and the “upper limit angle” read from the storage device 106 are stored in the RAM 103, and further, the RAM 103 is a captured image of the image captured in step S110 (FIG. 8). A storage area for temporarily storing files, a work area, and the like are provided.
[0073]
FIG. 11 is a diagram showing a monitor screen 105 a displayed on the display 12 by the display device 105. The monitor screen 105a shown in FIG. 11 is a screen on which an image temporarily captured by the digital camera 20 is displayed before shooting is performed after the shooting conditions are specified in the upper surface determination process shown in FIG.
[0074]
The monitor screen 105a shown in FIG. 11 includes a zoom setting frame 105b for setting the zoom of the digital camera 20, a focus setting frame 105c for setting the focus, an aperture setting frame 105d for setting the aperture, and a subject base 405. A pedestal position setting frame 105e for setting the elevating position of the hood 402, a hood position setting frame 105f for setting the rotation position of the hood 402, a camera holder position setting frame 105g for setting the tilt angle of the camera tilt base 403, and a subject base 405. A monitor frame 105h for monitoring the captured image of the set subject and a “CAL1” button 105j that is operated when the potentiometer 405b is calibrated are displayed.
[0075]
In each setting frame 105b to 105e, a slide button for adjusting each driving unit to a desired position, a “current position” and “target position” display frame for numerically displaying the current position and the target position of each driving unit, and each drive A “status” display frame for displaying the drive state of each part, and a “move”, “stop” button and the like for designating the drive state of each drive part are displayed.
Further, “current angle” and “target angle” displays indicating the current rotation angle of the hood 402 and the target angle are displayed in the setting frame 105f. Similarly, in the setting frame 105g, “current angle”, “Target angle” display is displayed.
[0076]
When various shooting conditions on the monitor screen 105a are designated in step S121 of the upper surface discrimination process shown in FIG. 9, the CPU 101 performs various operations so as to move and adjust each drive unit of the photographing apparatus 40 to the designated shooting conditions. An instruction signal is output to the imaging control device 30 via the cable C, and each drive unit of the imaging device 40 is moved and adjusted so as to correspond to the imaging conditions.
[0077]
The right side of the monitor screen 105a indicates that the monitor image temporarily captured by the digital camera 20 and the “mirror screen” that reverses the upper limit of the image captured by the digital camera 20 are set. A “mirror image inversion” display box 105i is displayed, and a “mirror inversion” button 105k for forcibly switching the setting of the “mirror screen” to the normal state is displayed below the monitor image.
[0078]
That is, in step S130 (FIG. 9), when it is determined that the shooting condition is a condition for shooting the upper surface of the subject and the display is switched to the “mirror screen”, the “mirror inversion” display box is displayed on the monitor screen 105a. 105i is displayed and the monitor image is inverted and displayed. As a result, it is possible to clearly notify the user whether or not the currently displayed image is an inverted image, so that the user can confirm, so that the inverted display is mistakenly mixed with the normal display. There is no end.
In addition, even if the user does not give an instruction to shoot the top surface of the subject or specify reverse display, it automatically detects that the shooting conditions for shooting the top surface of the subject have been specified and displays it on the monitor screen. Since the “mirror image inversion” display box 105i is displayed, a user's mistake can be prevented more reliably.
[0079]
As described above, according to the photographing system 1 in the first embodiment to which the present invention is applied, the subject (product) is photographed by moving each part of the photographing device 40 to the position specified by the input device 102. In addition, the angle of the hood 402 and the angle of the camera tilt base 403 specified by the input device 102 are detected by the angle sensor 403b and the angle sensor 407b, and the sum of these angles should be taken to photograph the upper surface of the subject (product). It is determined whether or not the angle is an angle, and if the front and top surfaces of the subject (product) can be photographed, the presence of an instruction input for photographing the front surface is detected and the top surface of the subject (product) is photographed. If it is determined, the display device 105 displays the monitor image of the subject (product) displayed on the monitor screen 105a in the “mirror screen” state in which the upper limit is inverted. Indicated was further displays a "mirror image flip" display box 105i in the vicinity of the monitor image.
[0080]
Therefore, regardless of whether the user intentionally instructs the upper surface to be photographed, when the upper surface of the subject (product) is photographed using the mirror 409, the image of the subject (product) is turned upside down. Since the image at the normal position is displayed, the image at the normal position is always displayed when the image capturing condition is specified and the digital camera 20 performs the image capturing. Therefore, the “mirror screen” state in which the user is erroneously displayed in reverse is not confused with the normal display state, and mistakes during shooting can be reliably prevented. As a result, mistakes that cause re-shooting can be prevented, so that it is possible to avoid an increase in work time and an increase in work load. In particular, when mistakes are likely to occur, such as when a large number of subjects are photographed continuously, a significant preventive effect can be obtained. The monitor screen 105a displays a “mirror inversion” display box 105i to clearly notify that the inverted image is displayed, so that an image obtained by inverting the image reflected in the mirror is displayed. Therefore, it is possible to more reliably prevent mistakes from occurring.
[0081]
Furthermore, according to the photographing system 1 in the above embodiment, the data indicating the position of each part of the photographing device 40 stored in the RAM 103 in the top surface photographing process (FIG. 9), indicating whether the photographing surface of the subject is the front surface or the top surface. Since various data such as data and data indicating whether or not the screen has been switched to the “mirror screen” is stored in the imaging condition table (FIG. 4A) stored in the storage device 106, the data subjected to the top surface imaging process And the shooting conditions indicated by the data can be easily reproduced. As a result, when shooting a subject (product) with a similar size or shape, it is not always necessary to execute the top surface shooting process every time, the work efficiency can be further improved, and the work time can be shortened. Is possible.
[0082]
In the above-described embodiment, the case where the monitor image is displayed in reverse is described. However, it is of course possible to invert only the captured image. Further, the image processing apparatus 10 may be provided with an audio output device having a speaker or the like so as to notify that it is in a “mirror screen” state by sound.
Alternatively, the digital camera 20 can be rotated in the horizontal direction, and the mirror 409 is installed on the side of the subject, and the side and back images of the subject reflected on the mirror 409 are photographed by the digital camera 20, and the photographed image is taken. It is good also as a structure which displays on the display 12 the reverse image which reversed left and right, and it can change suitably also about the structure of other details.
[0083]
Furthermore, in the above-described embodiment, the “mirror image reversal” display box 105i is displayed on the monitor screen 105a to notify that the state is the “mirror surface screen” in the reversed display. The display color of the peripheral edge of the monitor screen 105a may be switched only during the “mirror screen” state, and at the same time as the “mirror inversion” display box 105i is displayed, The display color of the edge may be switched.
[0084]
【The invention's effect】
According to the photographing apparatus of the first aspect of the present invention and the storage medium according to the fifth aspect, when the image of the photographing object reflected in the mirror is photographed by the camera, the image reflected in the mirror by the angle of the imaging surface of the camera When the camera is moved and rotated, an image with the mirror image inverted is displayed without performing settings to invert the captured image. The As a result, when shooting using a mirror, the captured image is inverted and the image at the normal position is displayed, and when the image of the subject is captured without using the mirror, the captured image is displayed as it is, The displayed image is always the image at the normal position. Therefore, no mistakes such as accidentally reversing a captured image that does not need to be reversed occur, so that it is possible to prevent a situation such as an increase in the work time and an increase in the burden on the worker due to a work mistake, and to improve work efficiency. Improvements can be made.
[0085]
According to the second aspect of the present invention, when an inverted image obtained by inverting the photographed image is displayed on the display means, the inverted image is displayed because it is displayed in a display state different from the normal state.

As a result, it is possible to more reliably prevent mistakes that confuse the state in which the captured image is displayed as it is and the state in which the reverse image is displayed, and improve operability.
[0086]
According to the third aspect of the present invention, when the inverted image obtained by inverting the photographed image is displayed by the display means, the guidance display indicating the inverted image is displayed, so the inverted image is displayed. It is clearly notified that Therefore, it is possible to more reliably prevent mistakes that confuse whether the displayed image is the captured image itself or a reverse image, and improve operability.
[0087]
According to the fourth aspect of the present invention, when the upper surface of the subject is photographed using the mirror installed above the subject housed in the case, the inverted image obtained by inverting the photographed image is displayed. The image at the normal position is always displayed on the display means. This makes it possible to set and check whether the image is a reversed image even when shooting a subject that is difficult to distinguish whether it is a reversed image at first glance, such as when shooting a subject with a very small bottom area. Therefore, it is possible to always obtain an image in the normal position, greatly improve work efficiency by improving operability, and prevent mistakes.
