Abstract
A split-counter architecture is implemented within an image sensor system. A first counter within an image sensor region counts image data from pixel regions within the image sensor region, and outputs the most significant bits of the image data to a second counter external to the image sensor region, reducing the bandwidth required between the image sensor region and the second counter, and reducing the size of the counters within the image sensor region.
