Title:
VIDEO IMAGE PROCESSING METHOD AND APPARATUS, AND DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/184850
Kind Code:
A1
Abstract:
A video image processing method and apparatus, and a device and a storage medium. The apparatus comprises: an obtaining unit for obtaining an area for superposition in a video image, the area for superposition comprising a plurality of display blocks (S1); an optical parameter statistical unit for performing optical parameter statistical processing on each display block to obtain an optical parameter statistical value, the optical parameter statistical unit being a hardware unit (S2); a determination unit for determining, on the basis of a difference value between the optical parameter statistical value and an optical parameter value of a target display character, whether adjustment processing is needed (S3); a character adjustment unit for adjusting the target display character to obtain a superposed character when the difference value is less than or equal to a preset threshold, a difference value between an optical parameter value of the superposed character and an optical parameter statistical value of a corresponding display block being greater than the preset threshold (S4); and a first subunit for superposing the superposed character with the corresponding display block (S51). According to embodiments of the present invention, the CPU load, the calculation amount, and the bandwidth are reduced, and the chip design complexity and the chip area are also reduced.
