Note:
Output size
The VS6663CC has the following methods available to achieve the required output size,
these can be used independently or in conjunction with any other:
• analog crop, see Section 6.1.1
• binning, see Section 6.1.2
• output crop, see Section 6.1.3
The VS6663CC does not support subsampling.
The programmable image size and output size are independent functions. It is the
responsibility of the host to ensure that these functions are programmed correctly for the
intended application.

Analog crop
The native size for the VS6663CC is 1280x 960, the maximum addressable array is 1296 x
976 which gives eight border pixels for the color reconstruction algorithms to use at the
edges of the array.
By programming the x_addr_start, y_addr_start, x_addr_end and y_addr_end registers it is
possible to use the full size of the array as you would do for a native size output or you can
select a “window of interest”. The addressed region of the array is used in any subsequent
binning operation.
