Output crop

The x_output_size and y_output_size registers are not intended as the primary cropping

controls.

They are intended to define the position of the LE/FE codes in the CCP2 data frame so that

the sensor does not need to calculate this based on analog crop or binning settings. It

should be expected that the host will set the output sizes to exactly enclose the output

image data. If the host should not do this, the VS6663CD treats the output size as being

calculated from the top left hand corner of the output array. So in the case where output

sizes are smaller than the output data, the data shall be cropped from its right-hand and

lower limits. In the case where larger than the output data, the lines shall be padded out to

the defined output size with undefined data.

The number of pixels between the line start and the line end sync codes for:

•

RAW8 is a multiple of 4 pixels

•

RAW10 is a multiple of 4 pixels for CSI-2 and a multiple of 16 pixels for CCP2

The host must control the x_output_size to ensure that the above criteria is met.
