US Patent 11153467 Image processing

A method and apparatus for processing image data is provided. The method comprises storing accumulated image data, obtaining a new frame of image data, performing motion detection based at least on the new frame of image data, updating the accumulated frame of image data, and generating output image data. The motion detection identifies a pixel location in which motion is detected. For the pixel location identified by the motion detection, a pixel intensity value of the new frame of image data contributes more to a pixel intensity value representing the identified pixel location in the updated accumulated imaged data than to a pixel intensity value representing the identified pixel location in the output image data.
