2.2 SIGNAL FLOW
In the general video-recording, CCD output is supplied to the Y/C circuit after correlative double sampling
and A-D conversion by the CDS/AD circuit, every necessary compensation, image processing and D-A
conversion by the DSP (Digital Signal Processor) circuit. However, when the "commemorative
photography button" is pressed, image data for one field is transferred from the DSP circuit to the DSC
circuit.
In the general video playback, video data recorded on video tape is played back. On the other hand, still
pictures saved in the memory built-in the DSC circuit are played back in the DSC playback mode.
