Abstract
An image photographing apparatus for storing interleaved data having a number of discrete analog values which is output from an image sensing section and digitized by an A/D conversion section includes an analog semiconductor memory device and a control section. The analog semiconductor memory device stores the interleaved data from the image sensing section as analog data. The control section writes the interleaved data output from the image sensing section upon photographing in the analog semiconductor memory device, reads out the written interleaved data from the analog semiconductor memory device, and outputs the data to the A/D conversion section.
