Camera Setup
Sub-Sampling
The camera can be enabled to sub-sample pixels in the specified image frame. Sub-sampling
can be specified as either 4:1 or 16:1, which signifies the sampling rate.
4:1
1 pixel output for every 4 pixels sampled. When selected the image will be sampled 2:1 in
the vertical direction and 2:1 in the horizontal direction for a combined 4:1 ratio. An image
with a dimension of 640 x 480 will be scaled to 320 x 240.
16:1
1 pixel output for every 16 pixels sampled. When selected the image will be sampled 4:1 in
the vertical direction and 4:1 in the horizontal direction for a combined 16:1 ratio. An image
with a dimension of 640 x 480 will be scaled to 160 x 120.
