Abstract
A system and method for electronic image stabilization for a high dynamic range image captured by a rolling shutter image sensor and more specifically to an algorithm configured to perform electronic image stabilization on the high dynamic range image, by, for each specific block of pixels among the blocks of pixels in the high dynamic range image, the specific block of pixels spatially corresponding to a pixel region of the rolling shutter image sensor, determining whether the specific block of pixels is copied from pixel data of the first image or the second image, or is a blend of pixel data from both the first image and the second image, and use motion data measured when capturing the first and second images for performing electronic image stabilization based on the origin of the specific block of pixels.
