MULTI-FRAME HIGH DYNAMIC RANGE (HDR) IMAGE GENERATION USING QUANTA IMAGE FRAMES

Abstract: a method includes obtaining, using a multi-mode image sensor, first image frames and second image frames. the first image frames include image data having a first bit depth, and the second image frames include image data having a second bit depth smaller than the first bit depth. the first image frames are captured using two or more exposure times, and the second image frames are captured using at least one exposure time shorter than the two or more exposure times. at least one of the second image frames is captured in between each consecutive pair of the first image frames. the method also includes providing at least the first image frames to a multi-frame processing (mfp) pipeline and processing at least the first image frames using the mfp pipeline to generate an output image.
