Abstract: The present application discloses a method of interpolating an image including a pixel array formed of multiple pixels. The method includes: determining a position of an interpolation point relative to the pixel array; determining weights of an edge direction of the pixel array at the position of the interpolation point in a plurality of preset edge directions based on pixel values of a plurality of pixels adjacent to the interpolation point; selecting, for each preset edge direction, one or more corresponding pixel sub-arrays covering the interpolation point from the pixel array to calculate an interpolation pixel value of the interpolation point; calculating a weighted interpolation pixel value of the interpolation point based on the weights of the edge direction of the pixel array at the position of the interpolation point in the preset edge directions and the interpolation pixel value of the interpolation point corresponding to each preset edge direction.

Abstract: According to a method in the present invention, first whether an inter-frame difference for each pixel in predetermined first region and second region in the dynamic image exceeds a predetermined threshold is judged to determine whether the pixel is a static information point, and when, in the second region, pixels in regions not overlapping with the first region are determined as non-static information points, judgment on the inter-frame difference and the predetermined threshold is stopped; and then static characteristic information in the dynamic image is determined based on the static information points in the first region. Preferably, the inter-frame difference for each pixel in the first region may be re-judged based on an adjusted predetermined threshold, to further determine the static characteristic information in the dynamic image, so that static opaque static characteristic information or static characteristic information with arbitrary degrees of transparency in the dynamic image can be detected.
