Column averaging/row binning circuit for image sensor resolution adjustment in lower intensity light environment

Abstract

A photo-sensor image resolution adjustment apparatus is in communication with an array of image photo-sensors that are organized in columns and rows and have multiple sensor types arranged in a pattern such as a Bayer pattern to detect light. The photo-sensor image resolution adjustment apparatus has a photo-sensor array decimation circuit to partition the array of image photo-sensors into a plurality of sub-groups. A column averaging circuit averages the light conversion electrical signals from common color photo-sensors within the sub-groups. A row averaging circuit averages the common color adjacent light conversion electrical signals from color adjacent rows within the sub-groups in high light intensity condition. In low light conditions, a row binning circuit integrates the common color adjacent light conversion electrical signals from color adjacent rows within the sub-groups.
