Title:
IMAGE PROCESSING ASSEMBLY, CHIP, IMAGE PROCESSING METHOD AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/267361
Kind Code:
A1
Abstract:
Provided in the present application are an image processing assembly, a chip, an image processing method and a storage medium. The image processing assembly comprises an address generation unit, a source image reading unit and an interpolation calculation unit, wherein the address generation unit is connected to the source image reading unit, and the source image reading unit is connected to the interpolation calculation unit; the address generation unit calculates source point coordinates of a target pixel point in a source image according to coordinates of the target pixel point, determines, according to the source point coordinates, a plurality of neighborhood integer coordinates corresponding to the source point coordinates, and determines a read address of each neighborhood integer coordinate in a memory according to the plurality of neighborhood integer coordinates corresponding to the source point coordinates; the source image reading unit obtains, by means of reading and according to the read address of each neighborhood integer coordinate in the memory, a pixel value corresponding to each neighborhood integer coordinate; and the interpolation calculation unit performs interpolation calculation according to the pixel value corresponding to each neighborhood integer coordinate, so as to obtain a pixel value of the target pixel point in an affine image which corresponds to the source image.
