(Operation of mobile phone 100)
Next, the operation (image data display processing) of the mobile phone 100 according to the present embodiment will be described with reference to FIGS. The image data display process is executed by an image data display program stored in the storage unit 103, but may be realized by a hardware configuration of the mobile phone 100 instead.

  First, after the mobile phone 100 is powered on, the main control unit 101 of the mobile phone 100 determines whether or not the mobile phone 100 is set to the imaging mode (step S101). That is, the main control unit 101 determines whether or not the imaging mode setting button 12 has been operated by the user.

  When determining that the imaging mode setting button 12 is not operated (step S101: No), the main control unit 101 continues the determination state (standby state) of whether or not the user has operated the imaging mode setting button 12 (step S101). .

  On the other hand, when the imaging mode setting button 12 is operated and the main control unit 101 determines that the mobile phone 100 is set to the imaging mode (step S <b> 101: Yes), the main control unit 101 receives the signal from the acceleration sensor 113. Based on the signal, it is determined whether or not the display screen 109 is in a vertically long state as viewed from the user holding the mobile phone 100 (step S102). That is, the main control unit 101 uses the operation of the imaging mode setting button 12 as a trigger, as shown in FIG. 4, when viewed from the user who owns the mobile phone 100, the mobile phone 100 makes the longitudinal direction the vertical direction. It is determined whether or not they are almost the same.

  Next, when the main control unit 101 determines that the display screen 109 is in the vertically long state (step S102: Yes), the image processing unit 111 displays the display screen from the image sensor 105 as shown in FIG. Rectangular (vertically long) image data (image data of 640 pixels long × 480 pixels wide) having the same vertical and horizontal ratio as 109 is extracted (step S106). Specifically, light (optical image of the intensity of light) incident from the camera device 104 has a pixel number of 640 × horizontal 640 in a square light receiving region in which a plurality of CMOS pixels in the image sensor 105 are arranged in a matrix. It has been converted to pixel image data. The image processing unit 111 extracts the image data of 640 × 480 pixels in the center from the image data. Thereafter, in order to display the image data on the display screen 109, the process proceeds to step S107.

  On the other hand, if the main control unit 101 determines that the display screen 109 is not in the vertically long state (step S102: No), the main control unit 101 proceeds to step S103.

  In step S107, the display control unit 112 displays the vertically long image data extracted from the image sensor 105 by the image processing unit 111 on the display screen 109 while maintaining the aspect ratio (see FIG. 4). Here, as shown in FIG. 4, since the display screen 109 is vertically long (display pixel length 640 × width 480 pixels), the information amount of the image data is held and the image quality is maintained. In other words, an image with the same image quality as that on the display screen 109 is displayed when the image sensor 105 is 640 × 480 pixels which are light receiving pixels compliant with VGA.

  In step S103, based on the signal from the acceleration sensor 113, the main control unit 101 determines whether or not the display screen 109 is in a horizontally long state as viewed from the user holding the mobile phone 100 (step S103). That is, as shown in FIG. 5, the main control unit 101 determines whether or not the mobile phone 100 substantially matches the longitudinal direction with the horizontal direction when viewed from the user who owns the mobile phone 100.

  Next, when the main control unit 101 determines that the display screen 109 is in the landscape state (step S103: Yes), the image processing unit 111 starts the display screen from the image sensor 105 as shown in FIG. Rectangular (horizontally long) image data (image data having a pixel number of 640 vertical by 480 horizontal) having the same vertical and horizontal ratio as 109 is extracted (step S104). Specifically, light (optical image of the intensity of light) incident from the camera device 104 has a pixel number of 640 × horizontal 640 in a square light receiving region in which a plurality of CMOS pixels in the image sensor 105 are arranged in a matrix. It is pixel image data. The image processing unit 111 extracts image data of 480 × 640 pixels at the center from the image data. Thereafter, in order to display the image data on the display screen 109, the process proceeds to step S105.

  In step S105, the display control unit 112 displays the horizontally long image data extracted from the image sensor 105 by the image processing unit 111 on the display screen 109 in a state where the aspect ratio is maintained (see FIG. 5). Here, as shown in FIG. 5, since the display screen 109 is horizontally long (display pixel length 480 × width 640 pixels), the information amount of the image data is held and the image quality is maintained. That is, an image having the same image quality as that of the case where the image sensor 105 is 480 × 640 pixels which are light receiving pixels compliant with VGA is displayed on the display screen 109.

  After the processes of step S107 and step S105, the main control unit 101 determines whether or not the imaging key 108a has been operated (step S108).

  When the main control unit 101 determines that the image capture key 108a has been operated (step S108: Yes), the image processing unit 111 moves from the image sensor 105 to be vertically long (640 × 480 pixels) or horizontally (vertically 480 × 640 pixels). ) Image data is read out and converted into a captured image (imaging data) (step S109). The captured image is stored as image data in the storage unit 103 by a predetermined key operation on the operation unit 108 of the mobile phone 100.

  Then, the main control unit 101 displays the captured image on the display screen 109 (step S110) and once ends the process.

  On the other hand, when the main control unit 101 determines that the imaging key 108a is not operated (step S108: No), the main control unit 101 continues the determination state as to whether or not the user has operated the imaging key 108a (step S108).

  Through the above processing, high-quality image data (vertically long (640 vertical) is displayed on the display screen 109 of the mobile phone 100 using an image sensor with a small display pixel number of 640 vertical by 480 horizontal pixels regardless of the orientation of the mobile phone 100. X 480 pixels wide) or horizontally long (480 x 640 pixels wide)).

  The captured image stored in the storage unit 103 can be displayed on the display screen 109 by the display control unit 112 by a predetermined key operation on the operation unit 108 of the mobile phone 100. At this time, processing for reading out image data from the storage unit 103 is performed instead of processing for extracting image data from the image sensor 105 (steps S104 and S106). Except for this reading process, the same processes as in steps S102 to S107 described above are performed, and high-quality image data is displayed on the display screen 109.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation and application are possible.

  In the above embodiment, the technical idea of the present invention is applied to the foldable mobile phone 100 in which the first casing 10 and the second casing 11 are connected to each other by the hinge portion 10a so as to be foldable. However, the present invention is not limited to this, and the technical idea of the present invention is that the first casing 20 having the vertically long display screen 109 is provided in the second casing 21 as shown in FIGS. The present invention can also be applied to a rotary mobile phone 200 configured to be rotatable around a rotating part (not shown). In the first casing 10 shown in FIG. 6A, a speaker 107 is disposed above the display screen 109, and a microphone 106 is disposed below the display screen 109. .

  In this example, as shown in FIG. 6A, when the first housing 20 is in the rotation position in which the display screen 109 is in the portrait state when viewed from the user who owns the second housing 21 of the mobile phone 200. The image data (image data with the number of pixels of vertical 640 × horizontal 480 pixels) is displayed in the vertical direction (display pixel vertical 640 × horizontal 480 pixels). Therefore, the information amount of the image data is retained and the image quality is maintained.

  On the other hand, as shown in FIG. 6B, when the first casing 20 is in the rotational position in which the display screen 109 is in the horizontally long state as viewed from the user holding the second casing 21 of the mobile phone 200, Image data (image data having a pixel count of 480 × 640 pixels) is displayed in a vertically long (display pixel: 480 × 640 pixels). Therefore, as in the case shown in FIG. 6A, the information amount of the image data is retained and the image quality is maintained.

  Moreover, although the aspect which displays a still image on the display screen 109 was demonstrated in the said embodiment, it is not restricted to this, The technical idea of this invention is applicable also to the aspect which displays a moving image. For example, it is possible to shoot a moving image while the mobile phone 100 is placed horizontally, and display the moving image while the mobile phone 100 is placed horizontally, that is, the display screen 109 is horizontally long.

  Furthermore, in the above embodiment, the number of pixels of the image data that the image processing unit 111 extracts from the image sensor 105 and the number of display pixels on the display screen 109 are the same. However, the present invention is not limited to this. The number of pixels of the image data extracted from the image data may be larger than the number of display pixels on the display screen 109 while maintaining the aspect ratio.
