High dynamic range sensor system with row increment operation

An apparatus includes a memory and a processor. The memory generally comprises a first memory buffer and a second memory buffer. The first and the second memory buffers may be independent of each other. The processor may be configured to store image data for a plurality of image frames in the memory. Each frame generally comprises a plurality of exposure regions having different exposure levels. The processor stores image data of all of the exposure regions for a particular image frame in one of the memory buffers along with respective overlap regions. The overlap regions are generated by the processor performing a row increment operation based upon symbols in an image data stream.
