Abstract
Devices and methods for determining image quality using full-reference and non-reference techniques. Full reference image quality may be determined prior to output of an image or video frame from an image sensor processor by temporarily retaining image data from the image sensor and comparing processed image data of the image to the retained, non-processed image data of the same image. Full reference image quality determination may be assisted by a heuristic-based fault indicator. Image quality may also be determined by a non-reference technique of matching the image to one of various scenarios that are associated with sets of heuristics and applying the heuristics of the particular scenario to the image. Instead of relying on a nominal frame rate, video timing quality may be determined by comparing the capture time interval between successive video frames to the presentation time interval of the same video frames.
