Abstract
An image sensor has a pixel cell array comprising clusters of pixel cell blocks each block having four pixel cells under the same microlens and filter wherein during readout electrical signals from two pixels positioned along a first diagonal are binned followed by binning the signals from two pixels positioned along the remaining second reverse diagonal in order to reduce spatial color artifacts associated with orthogonal binning schemes and minimize gaps or irregular spacing between optical centers within an image read out from the array of pixel cells.
