Abstract: The present disclosure discloses an image processing and display method, apparatus and device, and a computer storage medium thereof, belonging to the field of display technologies. The method includes: transmitting a first image of a first resolution to a display component at a first frequency in the case that the mode information indicates a first mode, wherein the first image is formed by splicing a plurality of sub-images of a second resolution; and transmitting a second image of the first resolution to the display component at a third frequency in the case that the mode information indicates a second mode, wherein n second images form a frame of image of the display component. The present disclosure provides two types of display modes. In one mode, a first image composed of a plurality of sub-images can be transmitted to a display component, such that the display component displays these sub-images at a higher frequency. In another mode, a frame of image can be transmitted to the display component a plurality of times.

Abstract: An image processing method, an image processing device, and a display device, relating to the technical field of image processing. In the method, interpolation processing is performed on an image to be processed, so as to obtain an interpolated image, and initial pixel values of respective interpolated pixels in the interpolated image are then updated, so as to reduce, for each interpolated pixel, the difference between a second-order derivative of the updated pixel value of the interpolated pixel and a second-order derivative of a pixel value of a target original pixel in the interpolated image, thereby reducing artifacts generated in the interpolated image, improving image continuity in the neighboring region of the interpolated pixels in the interpolated image, and improving the quality of the finally obtained processed image.
