US Patent 11373316 Apparatus and method for calculating motion vector

Provided an apparatus for obtaining a motion vector including at least one processor configured to receive a long exposure image and a short exposure image of the current frame, and obtain a motion vector of the long exposure image and a motion vector of the short exposure image, the processor being configured to extract feature points in the long exposure image based on a saturation degree of the long exposure image, and obtain a motion vector of the long exposure image based on a difference from a long exposure image of a previous frame, and the processor being configured to extract feature points in the short exposure image and obtain a motion vector of the short exposure image based on a difference from a short exposure image of a previous frame based on a saturation degree of the short exposure image.
