Method and apparatus for inputting and outputting images which outputs a normal frame under poor conditions including external vibrations

摘要

An image input apparatus and method which can display a normal frame even in a poor environment including an external vibration has the following arrangement. An image pickup unit (1, 2, 3) images an object to be photographed and generates image data. A storage unit (4) stores the latest image data generated by the image pickup unit (1, 2, 3). An output unit (7, 5, 8, 6) outputs the latest image data stored in the storage unit (4) if the image data generated by the image pickup unit (1, 2, 3) undergoes a change equal to or larger than a predetermined displacement, and outputs the image data generated by the image pickup unit (1, 2, 3) if the image data does not undergo a change equal to or larger than the predetermined displacement.
