摘要:
An image processor performing super-resolution of converting an input image with first resolution to an output image with second resolution higher than the first resolution on consecutive input images includes a prediction unit predicting the output image with the second resolution of a current frame using the input image of the current frame and the output image obtained by the super-resolution on an input image of a previous frame; a generation unit generating a reduced image with the first resolution composed of pixels at different phases of the prediction image using a prediction image obtained by the prediction of the prediction unit; a difference calculation unit calculating a difference between the input image of the current frame and the reduced image; and an addition unit adding the difference up-sampled to the second resolution to the prediction image, thus generating the output image with the second resolution of the current frame.
