Abstract
An image sensor having improved dynamic range includes a signal that is read out for a selection of pixels which act as a calibration to govern the choice of exposure levels to be applied to the rest of the array. In this way, the sensor is operable to adapt to variations in scene intensity. The pixels in the array are vertically and horizontally addressed so as to enable accounted for small areas of intensity variation across an imaged scene.
