Output size

The VS6663 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

Note:

The VS6663 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 VS6663 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.
