Title:
IMAGE PROCESSING APPARATUS AND METHOD, AND RELATED CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2019/041264
Kind Code:
A1
Abstract:
Provided are an image processing apparatus and method, and a related circuit. The image processing apparatus comprises a first control unit for determining first control information, corresponding to a target image to be generated, of a source image and a first interpolation coefficient, wherein the first control information represents data, used for generating the target image, in the source image; a first pre-fetch unit for selecting, from the source image, first input data corresponding to the first control information; a buffer for buffering the first input data; and a first filter for carrying out an interpolation operation based on the first interpolation coefficient and the first input data stored in the buffer to generate the target image, wherein the number of buffers is greater than or equal to the number of taps of the first filter. By means of determining useful data, used for generating a target image, in a source image, storing the useful data in a buffer and then carrying out subsequent processing, the overhead of a memory can be saved on, the utilization rate of storage resources can be improved, and thus the image processing efficiency can be improved.
