Abstract
An image sensor may include an array of imaging pixels arranged in rows and columns. Each column of imaging pixels may include a respective plurality of column output lines. Each column output line may be coupled to a respective subset of the imaging pixels in that column of imaging pixels. Each plurality of column output lines for a given column may be coupled to readout circuitry. Each group of column output lines may share a single respective sample and hold circuit and a single respective analog-to-digital converter. Alternatively, each group of column output lines may have one sample and hold circuit per column output line and each group of column output lines may share a single respective analog-to-digital converter. Alternatively, each group of column output lines may have one sample and hold circuit per column output line and may have one analog-to-digital converter per column output line.
