1. A method of wide dynamic range (WDR) multi-frame processing, comprising: receiving raw image signals from a WDR sensor comprising a plurality of frames that each include a plurality of pixels, said plurality of frames including a first frame having first exposure time pixel data (first pixel data) and at least a second frame having second exposure time pixel data (second pixel data), said first and said second pixel data having an intensity value; generating statistics for camera control including first statistics for said first pixel data and second statistics for said second pixel data; merging said first pixel data and said second pixel data using a WDR merge algorithm which utilizes said first statistics and said second statistics to generate a raw higher bit width single frame image; post-processing said raw higher bit width single frame image using at least a defect pixel correction algorithm, and performing at least a portion of tone mapping to said raw higher bit width single frame image after said post-processing to provide an output toned mapped image.
