An imager may be configured to perform pixel binning on captured images. Pixel binning may be performed by forming groups of pixels and combining sampled values from the pixels in each group. The sampled values from the pixels may be combined by assigning weights to each pixel, scaling the sampled values by the corresponding weights, and summing the scaled values. The groups of pixels and pixel weights may be selected to produce binned images with even spatial distribution. The pixel binning operation may be performed by processing circuitry that receives captured image data from the imager. The pixel binning operation may also be separated into a horizontal binning step and a vertical binning step that are performed by image readout circuitry during image readout. During the horizontal binning step, pixels of a particular row may be combined. During the vertical binning step, pixel rows may be combined.
