ALTERNATE PIXEL SAMPLING MODE
Logic 1 input on CKINV (Pin 94) inverts the nominal ADC
clock. CKINV can be switched between frames to implement
the alternate pixel sampling mode. This allows higher effective
image resolution to be achieved at lower pixel rates, but with
lower frame rates.
On one frame, even pixels are digitized. On the subsequent
frame, odd pixels are sampled. By reconstructing the entire
frame in the graphics controller, a complete image can be
reconstructed. This is very similar to the interlacing process
used in broadcast television systems, but the interlacing is vertical
instead of horizontal. The frame data is presented to the display
at the full desired refresh rate (usually 60 Hz) so that no flicker
artifacts are added.
