Abstract: A parallax appropriate for a viewer is determined. An iris-to-iris distance of a user is stored for each user. A viewer at the front of the display screen of a stereoscopic image display apparatus is photographed, and an iris image of the viewer is detected. Iris authentication is carried out, and if the same image as the detected iris image is stored, it is understood which user is the viewer. The iris-to-iris distance of the viewer is read. A parallax is determined from the read iris-to-iris distance, the distance from the display screen to the viewer, and the display screen size.

Abstract: Memory cards are respectively set in first and second slots to take a moving image. A memory controller records image data, which is produced from the taken image, in the memory card of the first slot. When available memory of this memory card runs out, the data is continuously recorded in the switched memory card of the second slot. While recording the data in the memory card of the second slot, the memory card of the first slot is exchanged to another one having available memory. When the available memory of the memory card of the second slot runs out, the data is continuously recorded in the switched memory card of the first slot again. Switching the slot and exchanging the memory card are alternately performed so that the moving image may be taken for a long time.
