Abstract:
An image sensor, comprising:a sensor array, including a two-dimensional array of digital pixels, each of said digital pixels outputting digital signals as digital pixel data in k bits, said sensor array outputting said k-bit digital pixel data representing an image of a scene, said digital pixel data being outputted in a sensor-bit arrangement where said k-bit digital pixel data are arranged in a bit plane format in k numbers of bit planes; a data memory, in communication with said sensor array, for storing said k-bit digital pixel data in said sensor-bit arrangement; and a pixel normalization circuit coupled to said data memory for rearranging said k-bit digital pixel data into a pixel-bit order and providing said rearranged pixel data as output signals, wherein said rearranged pixel data have all k bits of said digital pixel data associated with each digital pixel in a consecutive order.
