[0001]

TECHNICAL FIELD The present invention relates to a mobile phone and a PDA.
The present invention relates to a portable information terminal device such as (Personal digital assistant), and more particularly to a portable information terminal device having a camera function.

[0002]

2. Description of the Related Art In recent years, downsizing and low power consumption of image pickup devices, improvement of processing capacity of electronic devices and increase of memory capacity, and further increase of communication infrastructure speed and capacity (broadband) have been achieved. As a background, mobile information terminals such as mobile phones and PDAs have come to have a built-in camera function using a CMOS image sensor.

Since these portable information terminal devices are carried in a bag or in a pocket of clothes, a flip is provided in order to prevent erroneous operation of the operation keys of the device, and they are stored or carried during carrying. By closing the flip and covering the operation key part, it is possible to prevent the key from being accidentally pressed, and the one that has the LCD on one side and the operation key on the other side and is foldable It's getting more and more. In particular, when the folding type is used, there are advantages such as good storability at the time of folding, prevention of erroneous operation, protection of the liquid crystal screen, and mounting of a large liquid crystal display screen.

Further, in recent years, mobile phones, which have become more multifunctional and more sophisticated, have become capable of browsing electronic mails and accessing Internet contents in addition to the original call function, and more information can be stored at once. A foldable mobile phone that can mount a large LCD that can display
It tends to increase.

[0005] The number of devices having a camera function by incorporating a small image pickup module into these mobile phones is increasing.

As described above, there are many portable information terminal devices having a flip or folding mechanism and incorporating an image pickup module.

[0008]

On the other hand, the image pickup module built in these portable information terminal devices is required to be small and lightweight, and it is not possible to incorporate a zooming mechanism which a general camera has. Therefore, a single focus lens is used.

Therefore, the magnification and angle of view of the lens are fixed in a state suitable for snap photography, which is considered as a general method of using a camera with a built-in portable information terminal device, and cannot be changed.

Therefore, the method of using the camera incorporated in the portable device is limited to snap photography (without zoom).

Of course, a method of changing the angle of view by a so-called digital zoom, in which a part of an electrically picked-up image is enlarged and taken out, is conceivable. However, the built-in camera of a small portable device is small, lightweight, and consumes less power. Therefore, it is not possible to use an image sensor having a large number of pixels, and therefore, when using the digital zoom, there is a problem that the image quality deteriorates and a sufficient image quality cannot be obtained.

The present invention has been made in view of the above points, and an object thereof is to provide a portable information terminal device having a camera function, which can easily change the optical characteristics of the camera.

It is characterized in that the optical characteristics of the combined optical system according to the system and the optical characteristics of the first optical system are different from each other.

That is, according to the portable information terminal device having the camera function of the present invention, the optical performance of the entire system is changed by the second optical system provided on the lid member as the lid member moves. Therefore, the operation of moving the lid member and the operation of changing the optical characteristics can be linked. Further, since the second optical system can also be used by being inverted, the second optical system can give the device a plurality of optical characteristics.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

[First Embodiment] FIGS. 1A to 1E show a foldable mobile phone as a portable information terminal device having a camera function according to a first embodiment of the present invention. It is a figure which shows the external appearance of FIG. 2, (A) and (B) of FIG.
FIG. 6 is a diagram showing a positional relationship between the image pickup module and the adapter optical system when the mobile phone is folded in a non-inverted state and an inverted state.

That is, this mobile phone is connected to the housing 10 so as to be foldable with respect to the housing 10 as indicated by two bidirectional arrows in the drawing and rotatable by 180 degrees or more with respect to the housing. And a lid member 12 that is formed. More specifically, the housing 10 and the lid member 12 include a rotating shaft 11A,
It is coupled via 11B so as to be rotatable (displaceable) in two directions.

Such a coupling structure is generally used, for example, as a coupling mechanism of a display panel which can be opened / closed and rotated by a handy video camera as shown in FIG. 2 (C).

Therefore, the lid member 12 is shown in FIG.
As shown in FIG. 1, the housing 10 can be folded in a non-inverted state with the surface on which the operation keys 22 and the microphone 24 are disposed inside, and as shown in FIG. The cover member 1 is rotated by 180 degrees with respect to the housing 10.
It is also possible to fold it in an inverted state with the back surface of 2 facing inward.

The housing 10 is composed of an LCD, an EL (Electro-Luminescence) panel or the like on the inner surface when folded, and has a display unit 14 for displaying user interface information such as a telephone directory or operation menu display. When,
Imaging module (camera) 16 including an imaging device such as a CMOS sensor or CCD and a lens (first optical system) 16
And a speaker 18 are arranged. An antenna 20 is attached to the housing 10.

On the other hand, the operation key 22 is provided on the lid member 12.
In addition to the microphone 24, an adapter optical system 26 as a second optical system is arranged. In this case, the adapter optical system 26, as shown in FIGS. 2A and 2B, when the lid member 12 is non-inverted or inverted and folded,
It is arranged at a position substantially coincident with the optical axis of the image pickup module 16 of the housing 10. The adapter optical system 26 is composed of, for example, a lens, and can transmit light between both surfaces of the lid member 12, that is, when the lid member 12 is folded in a non-inverted state, light is transmitted from the back surface side of the lid member 12. In response to this, light enters the image pickup module 16 on the side of the housing 10 (first state). On the other hand, when the lid member 12 is folded in the inverted state, the light is emitted from the front surface side of the lid member 12. Upon receiving the light, the light enters the image pickup module 16 on the side of the housing 10 (second state).

The image pickup module 16 is shown in FIG.
As shown in (A) of FIG.
It has a filter or a cover glass 16C arranged between A and an image forming surface 16B on which the image pickup element is arranged, and a fixed diaphragm 16D arranged on the front surface of the lens. The object point distance is ∞ and the focal length fl is The optical characteristics are 7.72 mm and the angle of view ω is 25.4 °. In this case, the total length is 12 mm.

With such optical characteristics for far-point imaging, it is possible to take an image of the imaging module 16 toward the operator himself or to take a snapshot of the surrounding landscape or person of the photographer. it can. And the imaging module 1
The image captured in 6 can be stored in the memory of the mobile phone and displayed on the display unit 14, or can be attached to an electronic mail and transmitted to another electronic device.

It is also possible to use a mobile phone having such an image pickup module 16 as a videophone for talking while displaying the image of the caller picked up by each mobile phone on the display section 14 of the other party. is there.

On the other hand, when the lid member 12 is rotated by 180 ° and folded as shown in FIGS. 1 (E) and 2 (B), the lid member 12 is folded as described above, as shown in FIG. 3 (B). A lens 26A that constitutes the adapter optical system 26,
26B is inserted into the subject side. At this time,
The lens 26A of the adapter optical system 26 is arranged on the subject side, and the lens 26B is arranged on the imaging module 16 side. As a result, the overall optical characteristics are such that the focal length fl is 10.43 mm and the angle of view ω is 17. while maintaining the object point distance of ∞ similar to that of the imaging module 16 shown in FIG.
It can be 6 ° (in this case the total length is 19.
4 mm). That is, the magnification can be changed by inserting the adapter optical system 26.

With such optical characteristics, an object farther away can be imaged larger than when the image pickup module 16 alone is used. Therefore, the image pickup module 16 alone can be used to capture an image of an object such as a landscape or a person on the screen. It can be used for snapshots from a few meters away when objects become too small.

On the other hand, at the time of non-inverted folding as shown in FIGS. 1B and 2A, as shown in FIG. 3C, the lens 26A, which constitutes the adapter optical system 26, 26B is inserted into the subject side. However, in this case, the reverse of the reverse folding,
That is, the lens 26B is arranged on the subject side, and the lens 26A is arranged on the imaging module 16 side. As a result, the overall optical characteristics, that is, the optical characteristics of the synthetic optical system,
The object point distance is 200 mm, the focal length fl is 5.7 mm, and the angle of view ω is 34.0 °. At this time, the total length is 20.3m
m.

Such optical characteristics can be utilized for macro photography for enlarging and photographing an object at a short distance.

As described above, when the mobile phone is folded, the adapter optical system 26 arranged on the lid member 12 is located in front of the image pickup module 16 arranged on the opposite housing 10 and the optical axes thereof are aligned with each other. , The imaging module 16
The light beam incident on is changed by the adapter optical system 26,
When inverted and folded, it has a high-magnification optical characteristic for far-point imaging, and when it is not inverted, it has optical characteristics for near-point imaging.

In the above description, as the adapter optical system 26,
On the other hand, an example in which the object point distance is ∞ and the object point distance is 200 mm when the incident direction of the light beam to the adapter optical system 26 is reversed is shown. On the other hand, when the object point distance is ∞ and the object point distance is reversed, the object point distance is 20 mm. It is also possible to provide such optical characteristics that the object point closer to the near side is in focus.

In this way, by folding the mobile phone and inserting the adapter optical system 26, the optical characteristics of the camera can be changed in various ways, so that it can be used for various purposes.

As one of its uses, it is conceivable that the portable telephone can be operated as an optical mouse by adopting the adapter optical system 26 in which the object point on the near side is in focus when folded.

Are stored in the 1-frame delay circuit 106 which is a frame memory. Then, the image pickup device 104 picks up an image at a predetermined interval, and the image of the current frame picked up by the image pickup device 104 ((C) in FIG.
(N + 1 frame image in FIG. 4) and the image one frame before stored in the one frame delay circuit 106 (n frame image in FIG. 4C) are input to the inter-frame motion vector detection circuit 108. . The inter-frame motion vector detection circuit 108 extracts the features of the images captured at the predetermined intervals, and calculates the direction and magnitude of the motion, that is, the motion vector. Then, the calculated motion vector information is transmitted to an external electronic device 112 such as a PC via an external interface (I / F) circuit 110 as an output means, and the external electronic device 112 receives the received motion vector. Based on the information, processing such as moving the mouse cursor is performed. In this case, the external I / F circuit 1
10 is RS232C or USB (Universal Serial Bus)

communication), the motion vector information is transmitted to the external electronic device 112 by wireless communication such as Bluetooth or wireless LAN.

As described above, the optical mouse detects the relative moving direction and moving distance (that is, motion vector) of each subject image captured at different points in time, thereby detecting the relative position of the subject at the present time. The position information can be obtained.

Therefore, in this embodiment, in order to make the mobile phone function as such an optical mouse, a push button is provided on the side surface of the housing 10 as shown in FIG. As well as being used as the button 32, as shown in FIG. 5B, the LED for illumination of the optical mouse is provided on the imaging surface side of the adapter optical system 26 of the lid member 12.

Here, the display unit 14 is an LCD or EL.
It is composed of a panel or the like and displays user interface information such as a telephone directory or operation menu display. The illumination LED 34 is for illuminating an object to be imaged at the time of near-point imaging.

The folding detection switch 28 is for detecting that the portable telephone is folded, and the reversal detection switch 51 is for detecting that the lid member 12 is reversed. is there. These switches are provided, for example, in the vicinity of the rotating shaft 11A for folding operation of the housing 10 and the lid member 12 and in the vicinity of the rotating shaft 11B for rotating operation of the lid member 12, respectively, and perform the folding operation. Alternatively, for example, it is known that the lid member 12 is turned on when the lid member 12 is rotated by a predetermined amount in the middle of an operation (an operation for causing the optical axis of the lens 16A and the optical axis of the adapter optical system 26 to substantially coincide with each other). Of course, it may be a mechanical switch.

Further, the image processing section 38 uses a CCD or CMO.
Image sensor 1 configured by an S sensor and converting light from an object point imaged by a lens 16A into a corresponding electric signal
The image pickup signal from 6E is processed, filtering such as noise removal of the image and binarization are performed, and the interface between the CPU 36 and the image pickup device 16E is performed. Further, when the adapter optical system 26 is inserted and near-point photography is performed, that is, when the mobile phone functions as an optical mouse, the image processing unit 38 moves the one-frame delay circuit 106 of the optical mouse and movement between frames. It also has a circuit configuration that functions as the vector detection circuit 108.

The memory 40 stores photographed images and user information such as a telephone directory, and a key input section 42.
Are the operation keys 22 and the casing 10 arranged on the lid member 12.
The input of the mouse button 32 or the like arranged on the side surface of the is received and transmitted to the CPU 36.

Is an interface for communicating with an external electronic device 112 such as. In the present embodiment, Ir
It is assumed that communication is performed wirelessly such as DA, Bluetooth, or wireless LAN, but it goes without saying that communication may be performed by wire such as RS232C or USB.

The voice output unit 46 includes the speaker 18 for outputting voice during a call, an amplifier, etc., and the voice input unit 48 has the microphone 24 for inputting a voice of a speaker during a call. And amplifier.

The transmission / reception unit 50 performs processing for receiving a call from the other party and transmitting this call.

Next, the operation of the mobile phone having such a configuration will be described with reference to the operation flowchart of the CPU 36 shown in FIG.

First, when the power of the mobile phone is turned on,
The CPU 36 performs normal telephone operation processing such as waiting and talking (step S10). That is, since the power switch of the foldable mobile phone is usually arranged as one of the operation keys 22 of the lid member 12, the power is turned off.
In order to perform N, it has to be in the open state, and inevitably does not operate as an optical mouse used in the closed state. Therefore, in this case, the CPU 36 stops the operations of the illumination LED 34 and the external I / F 44, and also stops the one-frame delay and the inter-frame motion vector detection function of the image processing unit 38, the normal telephone operation process. Is to do.

Then, thereafter, it is determined whether or not there is an instruction to start the image pickup operation (step S12). Here, the instruction to start the imaging operation is given by menu selection by inputting a predetermined key of the operation key 22, but of course, a dedicated key may be provided. When there is no instruction to start the imaging operation,
Returning to step S10, the operation as a normal telephone is continued.

On the other hand, when there is an instruction to start the image pickup operation, the CPU 36 starts the operation of the image pickup device 16E and the image processing section 38, and the far point image pickup operation mode (the first image pickup mode). The normal mode) is entered, and the operation of the normal camera is started (step S13). In this operation mode, the camera operates as a normal camera such as a snap shot and a videophone.

Then, the folding detection switch 28 is
Depending on the state, it is determined whether or not the mobile phone is folded (step S14). If it is not folded, it is further determined whether or not there is an instruction to stop the imaging operation (step S15). Here, if there is an instruction to stop the imaging operation, the CPU 36 stops the operations of the imaging element 16E and the image processing unit 38, returns to step S10, and restarts the operation as the normal telephone. On the other hand, if there is no instruction to stop the imaging operation, the process returns to step S13 and the operation processing as the normal camera is continued. Here, the instruction to stop the image capturing operation is performed by selecting a menu by inputting a predetermined key of the operation keys 22 or inputting a dedicated key, similarly to the instruction to start the image capturing operation.

On the other hand, when it is determined in step S14 that the portable telephone is folded, it is further determined whether the lid member 12 of the portable telephone is inverted by the state of the reversal detection switch 51. Yes (Step S
16). Here, if it is reversed, the process proceeds to step S15 as in the case of not being folded, and it is determined whether or not there is an instruction to stop the imaging operation. If there is no such instruction, the process returns to step S13 and the normal camera is operated. Continue operation processing. However, the composite optical system including the image pickup module 16 and the adapter optical system 26 at this time has the same object point distance of ∞ as that of the image pickup module 16 alone, but has a characteristic of a larger magnification. Become. That is, it operates in a far point imaging operation mode (telephoto mode) which is a third imaging mode different from the normal camera operation when not folded.

On the other hand, when it is determined in step S16 that the lid member 12 of the mobile phone is not inverted, the CPU 36 performs near-point photography based on the combined optical characteristics of the adapter optical system 26. The operation of the optical mouse function as described above is performed using the image pickup module 16 which is set to the state of performing (step S17). That is, the operations of the display unit 14, the voice output unit 46, the voice input unit 48, and the transmission / reception unit 50 are stopped, and the illumination LED 34 is used.
In the second imaging mode, the operation of the external I / F 44, the one-frame delay of the image processing unit 38, and the motion vector detection function between frames are started to operate the imaging element 16E at a high frame rate. A certain near point imaging operation mode (positional information detection mode) is set, and the operation as an optical mouse is performed.

After that, the folding detection switch 28 is
It is determined whether the mobile phone is opened or not (step S18), and as long as it is in the folded state, the process returns to step S17 and the optical mouse function operation is continued. If the mobile phone is opened, the process returns to step S10 to perform the normal phone operation process.

As described above, according to the first embodiment, one adapter optical system 26 arranged on the lid member 12 is provided.
It becomes possible to use a foldable camera-equipped mobile phone as a wireless optical mouse by utilizing, and it is possible to provide a plurality of optical characteristics when a normal camera is used.

The one-frame delay circuit 106 of the optical mouse and the inter-frame motion vector detection circuit 108
Instead of configuring the image processing unit 38 with the function of
If 6 having a sufficient processing capability is used, the predetermined area of the memory 40 is used as the 1-frame delay circuit 106, and the motion vector detection circuit 1 between frames is used.
The function of 08 can be performed by the CPU 36 as software.

Further, the image pickup module 16 is operated by the operation key 22.
Alternatively, the adapter optical system 26 may be disposed on the display unit 14 side. In this case, the imaging module 16
The member having the operation keys 22 on the side where the adapter optical system 26 is disposed serves as a housing, and the member having the display unit 14 on the side where the adapter optical system 26 is disposed serves as the lid member. In the case of such a configuration, the third
The display unit 14 of the lid member is operated at the time of reversing folding, which operates as a far point operation mode (telephoto mode) that is the imaging mode of
The surface on which is arranged appears on the outside, and this can be used as a viewfinder at the time of image pickup.

[Second Embodiment] Next, the second embodiment of the present invention will be described.
An embodiment will be described.

The second embodiment adopts a code reading mode as the near-point imaging operation mode which is the above-mentioned second imaging mode. Specifically, close-up photography is possible at the time of non-inverted folding. Adapter optical system 26

For example, conventionally, data including voice, video, text, etc. is encoded, and the presence or absence of dots is defined according to "1" or "0" of the encoded data, and these dots are defined. It is well known that a dot code formed by arranging in accordance with a predetermined format is optically readable recorded on a recording medium such as paper.

Regarding this, the applicant of the present invention also discloses in Japanese Patent Laid-Open No. 6-2.

Therefore, according to this dot code 200, even if the size of the entire dot code 200 is larger than the image pickup field 214 of the reading device, in other words, the dot code 200 is picked up by the reading device in one shot. Even if it is not possible, if each address given to each of the above blocks 202 is detected in block units together with the data dots 206 included in each block, the data included in each block can be collected to obtain the original entire data. Since the data can be reconstructed, it is possible to record a large amount of data such as voice on a paper surface, and the data can be easily read even by manual scanning.

As a code reading device for reading such a dot code 200, the present applicant has proposed Japanese Patent Laid-Open No. 9-179930.

And a dot reading point detecting section 224 for calculating the reading point of each data dot 206 from
A dot reading unit 226 that reads each data dot 206 according to the reading point of each data dot 206 obtained in step 4, allocates a value of “1” or “0” to each data dot, and outputs the dot. A memory 228 that temporarily stores the data output from the reading unit 226; and a deinterleave & correction processing unit 230 that reads the data from the memory 228 and performs deinterleaving processing and error correction processing using Reed-Solomon code or the like. The audio reproduction unit 232 reproduces and outputs the original audio data by performing expansion processing of the error-corrected data.

On the other hand, the adapter optical systems 26a and 26b of the lid member 12 are symmetrical with respect to the rotating shaft 11B. It is attached at a place separated from the rotating shaft 11B by a predetermined distance.

For this reason, the optical axis of the adapter optical system 26a and the optical axis of the image pickup module 16 coincide with each other in the non-inverted folding, which is the folded state from the state of FIG. That is, the light is received from the back surface side of the lid member 12, transmitted through the adapter optical system 26a, and the light is incident on the imaging module 16 on the housing 10 side. On the other hand, at the time of reverse folding, which is a folded state from the state of FIG. 11B,
