1. An image super-resolution reconstruction method, comprising: an edge detection step of performing an edge detection on low-resolution images to be processed to obtain edge pixel frames, a frame amplification step of amplifying the edge pixel frames so that each amplified image is the double of the original edge pixel frame in size in both horizontal direction and vertical direction, without changing the detected edge pixel information, and a pixel compensation step of compensating for the interpolated interpolation pixels according to different pixel edges to obtain a high-resolution image.
