Abstract

The invention discloses an image processing method and device. The image processing method comprises steps of obtaining a COC value of each pixel of an image to be processed, performing layering on the image to be processed according to the COC value to obtain a multi-layer texture image, performing a following first operation on each pixel point in each layer of the texture image when a biggest value in each COC value range is smaller than or equal to a preset threshold to obtain a texture image after multi-layer processing, recording each pixel point as a first current pixel point, reducing the pixel value from a first current value to a first target value according to a COC value of the first current pixel point, setting pixel values of N first target pixel points around the first current pixel points as first target values, performing superposition processing on the texture image after multi-layer processing to obtain a target image having a depth of field. The image processing method and device solve a problem that: the prior art only performs sampling mixing on a fuzzy texture in the image on the main body of the object, which causes the image to be distorted when the depth is discontinuous.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to an image processing method and device. Background technique [0002] Objects can be clearly imaged within a range from the lens, but outside this range (near or far) the image is blurred. This effect is the depth of field. In industries such as photography and film, depth of field is often used to indicate the extent of attention to a scene and to provide a sense of scene depth. For example, in high-quality games, the depth-of-field effect that simulates the visual experience of the human eye has attracted more and more attention from players. [0003] At present, in order to obtain the depth of field effect of the image in the related art, the Z-buffer technology based on reverse mapping is usually used to obtain the depth of field. Vary the amount of pixels to blur the rendered scene. Wherein, for a pixel with a larger difference between the Z value and the focal plan...
