  As shown in FIG. 4, the camera module 110 includes a camera 116 and a strobe 118, which are connected to the control unit 107 in the second housing 104 via a control chip 120 and pin plugs 112 and 113. It has become so. In the camera module 110, a camera information memory 122 (corresponding to a performance information recording unit) is further connected to the control chip 120. Information related to the performance of the camera module 110 (number of pixels, CMOS) is connected to the camera information memory 122. / CCD, presence / absence of zoom, control command format, etc.) are encoded and stored.

  The memory 115 in the second housing 104 stores a plurality of code tables relating to different numbers of pixels. For example, codes related to 100,000 pixels, 330,000 pixels, 1 million pixels, and the like are stored. Each code of the memory 115 is stored in association with software for controlling the captured image to be displayed on the same LCD display unit 106, the optimum compression method, etc. even when the number of pixels is changed. Yes.

  Next, an operation procedure related to the camera module 110 of the mobile phone 100 according to the present embodiment will be described based on the flowchart of FIG.

  First, when the camera activation switch of the mobile phone 100 is turned on (step S1), the control unit 107 determines whether the camera module 110 is connected to the second housing 104 (step S2). Communication is performed between the (control unit 107) and the camera module 110 (control chip 120), and information such as the number of pixels of the camera is transmitted from the camera information memory 122 to the control unit 107 of the mobile phone 100, and the control unit 107 is a pin plug. Based on which of detection lines E and e of 112 and 113 is OPEN, it is determined which of the front and back of the camera 116 is facing, and further, image data processing setting (step S3) and flash light amount setting in the mobile phone 100 Control is performed so that initial setting such as (step S4) is performed.

  If the control unit 107 determines in step S2 that the camera module 110 is not connected to the second housing 104 (NO), a warning that the module is not connected is generated or displayed by sound or image (step S5). .

  The control unit 107 determines whether the mobile phone 100 is in a closed state in which the second housing 104 and the first housing 102 overlap (closed state), and the camera 116 of the camera module 110 faces the first housing 102 side. (Step S6), if YES is determined, a warning to that effect (the direction of the camera module 110 is reversed) is generated or displayed by sound or image (step S7).

  If NO is determined in step S6, an image (corresponding to a finder image of a normal camera) currently taken by the camera 116 that has performed image data processing according to the initial setting (step S3) of the camera module 110 is displayed on the mobile phone 100. Display (view display) on the LCD display unit 106 (step S8).

  When the shutter switch of the camera 116 is pressed (YES in step S9), a photograph is taken with the flash light amount of the strobe 118 according to the initial setting (step S4) (step S10), and the initial setting (step After image data processing according to S3) is performed (step S11), the captured image is displayed on the LCD display unit 106 (step S12).

  FIG. 6 is a flowchart for explaining in detail the processing contents of the image data processing setting in step S3 in the flowchart of FIG. In the image data processing setting, first, the control unit 107 detects the number of images of the camera 116 of the camera module 110 from a signal from the camera module 110 (step S31), and the number of pixels is determined by the LCD display unit 106 of the mobile phone 100. The control unit 107 determines whether the number of pixels is larger (step S32).

  When the number of pixels of the camera 116 of the camera module 110 is larger than the number of pixels of the LCD display unit 106 of the mobile phone 100 (YES in step 32), the mobile phone 100 is set to the image data extraction mode by the control unit 107 (step). S33).

  For example, when the size of the captured image is changed according to the number of pixels, the image captured by the VGA sized camera is four times the QVGA size, and therefore cannot be displayed on the QVGA sized LCD display unit 106. A 1/4 size portion is extracted from the image taken in step 1, and displayed on the LCD display unit 106, or reduced to a quarter size and displayed on the LCD display unit 106. Mode is set.

  When the number of pixels of the camera 116 of the camera module 110 is not larger than the number of pixels of the LCD display unit 106 of the mobile phone 100 (NO in step S32), this time, the number of pixels of the camera 116 is larger than the number of pixels of the LCD display unit 106. It is determined whether it is small (step S34). If YES is determined in this step S34, the image data interpolation mode is set (step S35).

  For example, when the size of the captured image is also changed with the number of pixels, the image captured by the QVGA size camera 116 is a quarter of the VGA size, so the VGA size LCD display unit 106 is too large. The image taken in step 1 is displayed in the center of the LCD display unit 106, and the remaining part of the periphery is white, or a decorative frame is displayed, or enlarged to a size four times on the LCD display unit 106. The display mode is set.

  If it is determined in step S34 that the number of pixels of the camera 116 of the camera module 110 is not smaller than the number of pixels of the LCD display unit 106 of the mobile phone 100 (NO), the number of pixels of both is determined by including step S32. In this case, the image data non-change processing mode is set (step S36).

  The image data non-change processing mode refers to the LCD display unit 106 that does not perform the image data extraction mode (step S33) nor the image data interpolation mode (step S35), and keeps an image taken by the camera 116 as it is. Is set to the mode to be displayed.

  FIG. 7 is a flowchart for explaining in detail the processing content of the flash light amount setting in step S4 in the flowchart of FIG. In the flash light amount setting, the control unit 107 first determines the orientation of the camera 116 of the camera module 110 (step S41).

  At this time, when it is determined that the camera 116 of the camera module 110 is facing the user (YES in step S42), considering that the subject is at a close distance or is in a bright place, A mode in which the flash light amount from the strobe 118 is minimized is set (step S43).

  If it is determined in step S42 that the camera 116 is not facing the user (NO), the camera 116 is facing away from the user, so that the subject is far away from the user, In consideration of the fact that the light is difficult to reach, etc., the mode in which the flash light amount from the strobe 118 is maximized is set (step S44).

  In the above-described embodiment, the mobile terminal device has been described in which the mobile phone 100 is opened and closed by rotating the first housing 102 around the shaft portion 105 with respect to the second housing 104. The present invention is not limited to this type of mobile terminal device, and the present invention can be applied to other types of mobile terminal devices in which, for example, two housings are opened and closed like a shell by a hinge. Is possible.

Further, although the description has been made based on the example in which the camera module 110 is mounted on the second housing 104, the present invention is not limited to this, and the camera module 110 may be mounted on the first housing 102. .
In addition, a strobe is shown as an example of the photographing auxiliary light source, but a light composed of an LED or the like may be used.

  In the above-described embodiment, the mobile phone 100 has been described. However, the present invention can also be applied to other types of mobile terminal devices such as PDA (Personal Digital Assistant).

  As described above, according to the present embodiment of the present invention, when shooting a user himself / herself or when shooting an object or person other than the user, an image to be captured is displayed on the image display unit, The user can perform a shooting operation while viewing the image displayed on the image display unit.

In addition, it is possible to provide a portable terminal device that can easily replace the camera.
Further, since the camera module 110 and the camera 116 do not protrude from the mobile phone 100, it is possible to prevent the camera module 110 from being easily damaged even if the mobile phone 100 is dropped. .

Further, since the camera module 110 is detachable, it is possible to prevent an increase in assembly man-hours, material cost, weight, etc. of the mobile phone 100 main body.
Further, only the above-described camera module 110 can be sold as a replacement part, or a service for preparing as a repair part can be performed, and the user can select a camera module corresponding to various uses and budgets. In this case, since it is not necessary to replace a mobile terminal device such as the mobile phone 100 to be used, there is no significant change in operability for the user.

In addition, the light amount of the strobe 118 of the camera module 110 can be automatically adjusted to an optimum value.
Furthermore, when the camera 116 of the camera module 110 is not used, the camera 116 is attached to the second housing 104 so as to face the first housing 102, so that the camera 116 faces the outside. Thus, the lens can be prevented from being easily damaged.
