Methods and integrated circuits to process image data from single or multiple digital overlap (DOL) wide dynamic range (WDR) sensors, in which first received pixel data associated with a first exposure of a sensor image is stored in a DDR memory circuit, second received pixel data associated with a second exposure of the image is stored in the first buffer, third received pixel data associated with a third exposure of the image is stored in a second buffer, and fourth received pixel data associated with a fourth exposure of the image is provided to a merge circuit, and merged pixel data is stored in a dynamically partitioned line buffer for processing by an image pipeline circuit to facilitate interfacing multiple DOL WDR sensors in an interleaved fashion.
