TV VIDEO SUPER-RESOLUTION PROCESSING METHOD AND TV VIDEO SUPER-RESOLUTION PROCESSING DEVICE USING THE METHOD, FIRST TO 14-TH SUPER-RESOLUTION PROCESSING PROGRAM, AND FIRST TO FOURTH STORAGE MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a TV video super-resolution processing method for subjecting a TV video to super-resolution processing, and a TV video super-resolution processing device.SOLUTION: The TV video super-resolution processing device includes PSF restoration means and image restoration means for, by software or hardware, executing iterative operations based on a real number on the basis of Bayes' probability theory, using, as input information, a brightness distribution of PSF identified according to a deterioration degree of a TV video, a brightness distribution of a deteriorated image including a Y (brightness) component of the TV video, and an estimated brightness distribution of a restoration image initial value. The PSF restoration means and the image restoration means are used to acquire an estimated brightness distribution of a restoration image which is most plausible to a brightness distribution of the deteriorated image, and the estimated brightness distribution is replaced with a Y component of the TV video when the brightness distribution of the deteriorated image is extracted. Thus, a TV video is provided which is close to a pre-deteriorated state at a substantially real-time.
