Abstract

An image pick-up section generates an electronic still image signal. An A/D conversion section converts the electronic still image signal generated by the image pick-up section into a digital signal. A conversion section converts the digital signal converted by the A/D conversion section into a plurality of streams of signals. A recording section includes a plurality of memories for respectively storing the plurality of streams of signals converted by the conversion section. A control section includes a section for sequentially controlling at least the plurality of memories of the recording section in a write enable state.

Claims

1. An electronic still camera, comprising:

image pick-up means for generating an electronic still image signal;

analog-to-digital (A/D) conversion means for converting the electronic still image signal generated by said image pick-up means into a corresponding digital signal;

conversion means for converting the digital signal converted by said A/D conversion means into a plurality of streams of signals;

recording means including a plurality of memories for respectively recording the plurality of streams of signals converted by said conversion means; and

control means including means for sequentially controlling at least said plurality of memories of said recording means in a write enable state,

wherein said conversion means includes a predetermined number of conversion circuits integrated in said plurality of memories, respectively.

2. A camera according to claim 1, wherein said recording means includes electrically erasable programmable read-only memories (EEPROMs) for respectively recording the plurality of streams of signals.

3. A camera according to claim 1, wherein said conversion means includes a decoder.

4. A camera according to claim 1, wherein each of said predetermined number of conversion circuits includes a serial-to-parallel converter.
