4-3 Camera/Card Signal Processing (DC20 E)
4-3-1 2-Megapixel Camera System
This model handles the increased CCD picture element readout by splitting the CCD into right and left halves and having two circuit
systems for readout, as shown illustrated above.
The two systems of video signal are distinctly subjected to A/D conversion, are composed into a single image by MPX-IC, and are sent
to DIGIC DV for camera signal processing.
