Abstract

See full text

A signal processing chain implements wide dynamic range (WDR) multi-frame processing including receiving raw image signals from a WDR sensor including a plurality of frames including a first frame including first exposure time pixel data and a second frame including second exposure time pixel data. Statistics for camera control are generated including first statistics for the first pixel data and second statistics for the second pixel data. The first and second pixel data are merged using WDR merge algorithm in a WDR merge block which utilizes the first and second statistics to generate a raw higher bit width single frame image. The single frame image is post-processed in post-processing block using at least a defect pixel correction algorithm, and at least a portion of tone mapping is performed on the single frame image after the post-processing to provide an output toned mapped image.
