Abstract
Embodiments include a method for eliminating an interference pattern in an image, and an apparatus, and relate to the image processing field, which can eliminate an interference pattern in an image collected by a time-of-flight (ToF) sensor arranged under a display screen of an electronic device. The method includes: obtaining, by the electronic device in advance, K interference patterns corresponding to K different values of a same parameter one by one; collecting, by the electronic device, a first image, and measuring a first parameter value in a case that the first image is collected; determining a first interference pattern in the K interference patterns according to the first parameter value, and determining the second interference pattern according to the first interference pattern; and eliminating the second interference pattern in the first image, so that the processed first image does not include the interference pattern.
