Abstract:
1. An image processing system comprising: a geometric transformation parameter computing unit for computing a geometric transformation parameter which represents a geometric transformation of an image from a previous frame to a current frame and calculating a level of reliability in the geometric transformation parameter; a super-resolution image prediction unit for generating a prediction of a super-resolution image in the current frame by transforming a super-resolution image generated in the previous frame on the basis of the geometric transformation parameter; and a super-resolution image generation unit for generating the super-resolution image in the current frame by calculating a low-resolution image in the current frame from the prediction result of the super-resolution image in the current frame by a simulation, calculating a difference between a low-resolution image, which is an input image for the current frame, and the low-resolution image calculated by the simulation, and calculating a weighted mean between a result of upsampling the difference to the same number of pixels as that of the super-resolution image and the prediction result of the super-resolution image in the current frame, wherein the super-resolution image generation unit calculates the weighted mean on the basis of the level of reliability in the geometric transformation parameter.
