Abstract
An image sensor includes a pixel structure which pair-wise vertically shares at least one read node, and further comprises a memory node for storing charges. A vertical transfer control line commands charge transfer from the photodiode to the memory node of a given column. The vertical transfer control rows apply two different exposure times, a first to the even columns and a second to the odd columns. The pixels and the read circuit perform one read operation per vertical pair of pixels over the exposure time associated with the column of the pair. A processing block is configured to calculate, for each vertical pair of pixels, an interpolated digital value. A periodic pattern of colored filters creates an HDR-mode color image sensor.
