Abstract
A method of generating a super-resolution image from a single frame of image data, includes receiving, at a processor, a frame of image data have a first resolution as an original image layer, generating an estimated super-resolution image as a high resolution image layer, the estimated super-resolution image having a second resolution, the second resolution being higher than the first resolution from the frame of original image data, generating a low resolution image layer by down sampling the frame of image data, the low resolution image layer having a resolution lower than the first resolution, down sampling the estimated super-resolution image to produce an intermediate image layer having an intermediate resolution between the first resolution and the second resolution, and selectively copying image data from the original image layer to the super-resolution image layer to produce a final super-resolution image.
