Pixel Sub-Sampling
4:1
At
4:1
, 4 pixel signals from 2 adjacent rows and columns are combined so that only 1 pixel
is output for every 4 pixels sampled. An image with the dimensions 640 x 480 is scaled to
320 x 240.
Since the resolution of the output image is reduced, the frame rate will increase, but not by
the factor of the image reduction. This is due to the overhead time of digital pixel data
processing and minimum row time requirements of the image sensor.
16:1
At
16:1
, 16 pixel signals from 4 adjacent rows and columns are combined so that only 1
pixel is output for every 16 pixels sampled. An image with the dimensions 640 x 480 will be
scaled to 160 x 120.
Since the resolution of the output image is reduced, the frame rate will increase, but not by
the factor of the image reduction. This is due to the overhead time of digital pixel data
processing and minimum row time requirements of the image sensor.
