The number of each area is displayed in each frame. Then, the superimposing unit 107 outputs the superimposed image data to the display unit 108.
- Display unit 108 superimposes the superimposed image input from overlay unit 107 on the preview image based on an instruction from image capturing control unit 109, and displays information related to the image capturing. Output to the control unit 109.
- the image capturing control unit 109 includes timing information input from the image capturing determining unit 106, information regarding recording of image data input from the image recording unit 103, information regarding the focus input from the autofocus unit 105, and a display unit Based on the display information input from 108, image capture control is performed !, image data recording instruction to image recording unit 103, focus adjustment instruction to autofocus unit 105, and display unit 108 are controlled. Display instructions.
- FIG. 2 is a diagram showing an external appearance of the mobile phone 200.
- the mobile phone 200 is, for example, a portable mobile terminal device, and includes all the configurations shown in FIG.
- the mobile phone 200 is arranged at a position where the camera unit 101, the auto focus area selection unit 104, and the display unit 108 (not shown) can be visually recognized from the outside in an operable state.
- the display unit 108 is composed of, for example, a liquid crystal display, and displays an overlapped image for selecting an autofocus area on the preview image in an image capturing mode in which the image is captured.
- the preview image is divided into nine autofocus areas # 201 to # 209, and consecutive numbers 1 to 9 are displayed in each autofocus area # 201 to # 209. .
- the autofocus area selection unit 104 includes buttons 211 to 219 which are pressing parts of the pressing switch and a determination button 210 which is a shutter for starting a photographing process. Buttons 21 to 219 are used to specify the phone number of the other party in the non-image shooting mode, which is a state where no image shooting is performed, and to specify the content when browsing a web page connected to a network such as the Internet.
