CREATING A COMPOSITE IMAGE FROM MULTI-FRAME RAW IMAGE DATA

摘要

A method, a system, and computer program product for creating a composite image from multi-frame raw image data. The method includes extracting each individual frame from a plurality of frames within raw image data and determining a sharpness score for a region of each individual frame. A particular frame that has a sharpest region from among the plurality of frames is then selected as a reference frame. Each pixel in the reference frame is then registered to a plurality of corresponding pixels from non-reference frames of the plurality of frames. Equivalent pixels from the reference frame and each non-reference frame are then summed to create a composite image.

1. A method comprising:
extracting each individual frame from a plurality of frames within raw image data; determining a sharpness score for a region of each individual frame; the image generating component selecting, as a reference frame, a particular frame that has a sharpest region from among the plurality of frames; registering, to each pixel in the reference frame, a plurality of corresponding pixels from non-reference frames of the plurality of frames; and creating a composite image by summing a plurality of registered pixels for each pixel in the reference frame.
