Abstract: A method and apparatus of digital image processing that provides pixel based image correction. The method and apparatus provide a digital processing cell that includes first and second processing modules. Each processing module includes a gate array. The gate array includes a digital video processing module and a switch portion configured to couple the digital video processing module to at least one of primary and secondary video buses and to couple the digital video processing module to at least one of primary and secondary neighborhood buses. An image processing system includes a plurality of such digital processing cells and an image sensor that outputs image data. The digital processing cells process the output image data.

Abstract: An encoder includes a linear offset amplifier, a linear analog to digital converter coupled to the linear offset amplifier, a switched offset amplifier, a switched analog to digital converter coupled to the switched offset amplifier, and a video controller. The video controller is coupled to both the linear and switched analog to digital converters. The video controller is configured to set both gains and offsets of the linear and switched analog to digital converters so that the gain and offset of the linear analog to digital converter is different than the gain and offset of the switched analog to digital converter.
