Classification: CPC H | IPC H

Claim 8:
9. A method for processing, in an integrated circuit, image data from a digital overlap (DOL) wide dynamic range (WDR) sensor, the method comprising:
receiving pixel data corresponding to multiple exposures of an image;
storing first received pixel data associated with one or more first ones of the exposures of the image in a shared memory circuit of the integrated circuit;
storing second received pixel data associated with one or more second ones of the exposures of the image in a first buffer of the integrated circuit;
storing third received pixel data associated with a third exposure of the image in a second buffer of the integrated circuit;
selecting, by a first multiplexer coupled to two or more outputs of the shared memory circuit, first pixel data from the shared memory circuit;
selecting, by a second multiplexer coupled to outputs of the first and second buffers, second pixel data from the shared memory circuit;
performing merge processing of the first and second selected pixel data to create merged pixel data representing the image;
storing the merged pixel data to a corresponding partition of a line buffer for separate access by an image pipeline circuit of the integrated circuit; and
processing the merged pixel data using the image pipeline circuit.
