HDR METHODS FOR GENERATING HDR HIGH DYNAMIC RANGE IMAGES AND APPARATUSES USING THE SAME

摘要

A method for generating an HDR (High Dynamic Range) image, performed by a processing unit, the method comprising: at least: obtaining frame 0; Obtaining frame statistical information including at least a first pixel count for the dark region and a second pixel count for the saturation region; Calculating a ratio according to a first pixel count and a second pixel count; Calculating a first enhancement factor and a second enhancement factor according to a ratio and an exposure setting of frame 0; Expanding frame 0 to HDR space using a first expansion factor; Expanding Frame 1 into HDR space using a second expansion factor; Includes fusing extended frame 0 with extended frame 1.
