Abstract
An apparatus includes an input interface circuit and a processing circuit. The input interface circuit may be configured to receive a high dynamic range (HDR) image data stream. The HDR image data stream generally comprises a plurality of HDR image frames comprising a plurality of exposure regions having different exposure levels. The processing circuit may be configured to store image data for the plurality of HDR image frames in a memory. The processing circuit generally issues write commands to store the image data of all of the exposure regions for a particular HDR image frame in one of a plurality of memory buffers in the memory. The processing circuit generally issues row increment commands during one or both of blanking periods and sensor overlap regions of the HDR image frames based upon symbols in the HDR image data stream.
