The control unit 2 that detects the moving distance calculated by accumulating the moving direction of the terminal, the magnitude of the acceleration, and the duration and controls the image displayed on the image display unit 3 that is a display unit, and the control unit 2 The image display unit 3 displays a scrolled or enlarged / reduced image, and the image data storage unit 4 stores the image data 5 displayed on the image display unit 3 by the control unit 2.

  Next, the operation of this embodiment will be described with reference to FIGS.

  As shown in FIG. 2, when the acceleration sensor 1 does not detect acceleration due to movement of the mobile terminal 6, the control unit 2 does not perform any processing on the image, so the image displayed on the image display unit 3 does not change.

  When the control unit 2 detects the movement of the mobile terminal 6 from the acceleration data detected by the acceleration sensor 1 (S201), the control unit 2 performs processing (S202 to S213) corresponding to the moving direction of the mobile terminal 6 on the display image. Do it. Specifically, when the acceleration sensor 1 detects the movement in the back direction 7 with respect to the image display unit 3 of the portable terminal 6 (S202), the control unit 2 enlarges the image displayed on the image display unit 3 ( When S208) is performed and the movement in the front direction 12 is detected (S203), the image display displayed on the image display unit 3 is reduced (S209). Further, when the acceleration sensor 1 detects the movement in the right direction 11 (S204), the control unit 2 performs the left movement (S210) of the image displayed on the image display unit 3, and detects the movement in the left direction 10. When this is done (S205), the image displayed on the image display unit 3 is moved rightward (S211). Further, when the acceleration sensor 1 detects a movement in the upward direction 9 (S206), the control unit 2 performs a downward movement (S212) in the image displayed on the image display unit 3, and detects a downward movement in 8 When this is done (S207), the image displayed on the image display unit 3 is moved upward (S213).

  The image enlargement (S208) is performed when the control unit 2 enlarges an enlarged image centered on the image displayed on the image display unit 3 from the image data 5 stored in the image data storage unit 4 in proportion to the movement distance in the back direction. And are displayed on the image display unit 3. In the image reduction (S209), in contrast to the image enlargement (S208), the control unit 2 reduces the image centered on the image displayed on the image display unit 3 from the image data 5 in the image data storage unit 4. Are generated at a reduction ratio proportional to the moving distance in the forward direction and displayed on the image display unit 3.

  In the leftward movement of the image (S210), the control unit 2 is proportional to the rightward movement distance of the terminal from the image data 5 in the image data storage unit 4 to the left image of the image displayed on the image display unit 3. The image at the position corresponding to the number of pixels is displayed on the image display unit 3. Similarly, the rightward movement (S211), the downward movement (S212), and the upward movement (S213) of the image are also opposite to the movement direction of the terminal from the image data 5 in the image data storage unit 4 by the control unit 2. The image at the position of the number of pixels proportional to the moving distance is displayed on the image display unit 3. When a plurality of moving directions are detected, the processing of the plurality of images may be performed simultaneously.

  Thus, according to the present embodiment, the control unit detects the vertical and horizontal movement directions from the acceleration detected by the acceleration sensor, and scrolls the image without operating the buttons of the portable terminal 6 or the like. By making it possible to perform image display operations with an intuitive operation of moving the user interface, a user-friendly interface can be realized.

  In the above description, the control unit 2 enlarges the image displayed on the image display unit 3 when the acceleration sensor 1 detects the movement in the back direction 7 with respect to the image display unit 3 of the portable terminal 6 (S202). When (S208) is performed and the movement in the front direction 12 is detected (S203), the image display displayed on the image display unit 3 is reduced (S209). However, the reverse control may be performed. . That is, the control unit 2 reduces the image displayed on the image display unit 3 when the acceleration sensor 1 detects the movement in the back direction 7 and displays the image display unit 3 when the movement in the front direction 12 is detected. The image display may be enlarged. Similarly, when the acceleration sensor 1 detects the movement in the right direction 11 (S204), the control unit 2 performs the left movement (S210) of the image displayed on the image display unit 3, and moves the left direction 10 in the left direction. When detected (S205) and the rightward movement (S211) of the image displayed on the image display unit 3 is performed, the reverse control may be performed. Similarly, when the acceleration sensor 1 detects a movement in the upward direction 9 (S206), the control unit 2 performs a downward movement (S212) in the image displayed on the image display unit 3, and moves the downward direction 8 in the downward direction. When detected (S207) and the image displayed on the image display unit 3 is moved upward (S213), the reverse control may be performed.

  In the present embodiment, the movement detection is performed by an acceleration sensor, but the movement detection may be performed by a gyroscope or a geomagnetic sensor. In this way, the movement of the image can also be controlled by rotation.
