  • Method for processing image, electronic device, and storage medium
    Patent number: 11954836
    Abstract: A method, electronic device and storage medium for processing an image using depth-of-field information is disclosed. The method includes obtaining a weight matrix and a weight image based on depth-of-field data of an input image; obtaining a first horizontal summed area table corresponding to the weight matrix and a second horizontal summed area table corresponding to the weight image by performing horizontal summing operation on the weight matrix and the weight image; obtaining a first weighted blurring image corresponding to the weight matrix based on the first horizontal summed area table, and obtaining a second weighted blurring image corresponding to the weight image based on the second horizontal summed area table; and obtaining a pixel value of the pixel in a target image based on the first and second weighted blurring images.
