Abstract
Official abstract text for this publication.
Methods and devices for improving dynamic range in image sensors are disclosed. An image sensing device comprises an image sensor having a plurality of rows of pixels, and a controller for controlling the exposure of each row of pixels. The controller is programmed to perform a shutter operation for one of the plurality of rows of pixels, and to sample the one of the plurality of rows after a predetermined duration following the performance of the shutter operation. The predetermined duration is different from a multiple of a row time period of the image sensing device.
