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 comprising:a nonvolatile analog semiconductor memory device disposed ahead of said A/D conversion section and having a large plurality of memory cells for individually storing the interleaved data from said image sensing section as analog potentials to store analog data which is discrete in time sampling scale and continuous in signal intensity scale; a control section for writing the interleaved data output from said image sensing section upon photographing in said analog semiconductor memory device, reading out the written interleaved data from said analog semiconductor memory device, and outputting the data to said A/D conversion section; and output selection means for outputting the interleaved data from said image sensing section to one of said analog semiconductor memory device and said A/D conversion section.
