Abstract
The present disclosure provides a method for generating HDR images. Steps of the method include capturing a spatially varying exposure image data of a scene by an image sensing array using a first exposure value and a second exposure value, wherein the first exposure value is larger than the second exposure value; re-sampling the spatially varying exposure image data to obtain a first image data corresponding to the first exposure value and second image data corresponding to the second exposure value; determining a motion index of each pixel of a HDR image data according to the first image data and the second image data; determining a pixel value of each pixel of the HDR image data according to a corresponding first pixel value of the first image data, a corresponding second pixel value of the second image data and the motion index; and outputting the HDR image data.
