Title: COMBINING IMAGES ALIGNED TO REFERENCE FRAME
Abstract:
In various examples there is an image combiner comprising a memory storing two or more frames being images depicting the same scene; and at least one processor. The memory holds instructions executable by the processor to select at least one of the frames and designate it as a reference frame and to designate the other frames as target frames. The instructions align the target frames to the reference frame and compute an output image by combining the reference frame and the aligned target frames. The process of selecting the reference frame comprises any one or more of: local analysis of characteristics of the frames, face detection, smile detection, object detection, computing signal to noise ratio of individual frames, use of sensor data from at least one non-camera sensor.
