Bit depth reduction of image pixels

Abstract:

The bit depth of the pixels in a camera image are reduced. In one embodiment, the number of pixels for each of a set of multiple bit intensity values is counted. A pixel intensity value with a lowest count is selected and a mapping function is generated that combines the pixels with the lowest count with pixels having an adjacent pixel intensity value. This is repeated until a total number of pixel intensity value counts is reduced to a predetermined number. A reduced bit depth image is generated using the predetermined number of pixel intensity value counts by assigning a new pixel intensity value to each of the pixels using the mapping function and the reduced bit depth image is sent to an image analysis system.
