In addition, the incident light from the second opening is switched to take an image. At this time, the incident light switching drive unit 107 is driven and controlled based on the settings stored in advance in the mobile communication terminal 100 or the user settings.

  FIG. 3 shows an example in which the incident light switching drive unit 107 is controlled based on the opening angle of the upper and lower units. As shown in the figure, when an imaging operation is performed by the user (step S101 / YES), the open / close state and open / close angle between the upper unit and the lower unit are detected (step S102). When the open state is less than a predetermined angle (for example, 90 degrees) set in advance (step S102 / less than a predetermined value), the incident light from the second opening provided on the outer surface side of the mobile communication terminal 100 is The selected image is picked up (S106).

  On the other hand, when the upper unit and the lower unit are opened and closed at a predetermined angle (for example, 90 degrees) or more (step S102 / predetermined value or more), the incident light inside and outside is switched to display an image. Obtain sequentially (step S103). Then, the determination of the acquired image (for example, the presence or absence of a person) is determined by a determination unit (not shown) such as a known image recognition engine (step S104), and the subject (for example, a person) is placed on the outer surface side of the mobile communication terminal 100. When the presence is determined (step S105 / YES), the incident light from the second opening provided on the outer surface side is selected to capture an image (step S106).
