Figure 7.1 Input Video Data Formats
7.1.3 Cropping
A cropping rectangle (or window) is supported for cropping or clipping the incoming video data. Only
interested video data located inside the cropping rectangle is processed and sent to the host system.
The cropping rectangle can be moved within the input rectangle by programming the Cropping
Window Start X and Cropping Window Start Y registers. Cropping is performed based on the VS
signal for vertical cropping and HS signal for horizontal cropping. Both VS and HS are programmable
polarity for maximum flexibility.
7.1.4 Scaling
The cropped video can be down-scaled horizontally and/or vertically. The horizontal down-scaling and
vertical down-scaling are performed independently by using two DDAs (Digital Differential
Accumulator) with
Horizontal Down-scaling Factor
Captured Video Width
Cropping Window End X
Cropping Window Start X
and
Vertical Down-scaling Factor
Captured Video Height
Cropping Window End Y

The W9967CF does not perform up-scaling during video pre-processing. To produce CIF format from
240-line video for the JPEG compression, a special vertical up-scaling can be performed by the
JPEG encoder. For the original video transfer, the CIF format from 240-line video can be produced
