Problems solved by technology

However, because existing image depth-of-field processing methods do not take into account optical and physical conditions, it is impossible to effectively estimate the degree of image blur between non-specific objects and specific objects, resulting in discontinuous or unnatural images in blurred captured images

Abstract

The invention discloses an image field-depth processing method. The method comprises that a background image and a foreground image are obtained from an original image according to a depth map corresponding to the original image, and the depth value of background image is greater than that of the foreground image; the background image is made fuzzy; the foreground image and a local image in the fuzzy background image are made fuzzy; and then, an analog image is formed according to the foreground and background images. The foreground image and the local image in the background image are made fuzzy according to the depth value of the foreground image, so that transition between the foreground image and the background image satisfies physical principles of geometrical optics more, natural and continuous image effects are achieved, further, a fade-in fade-out program is executed to fade a boundary image in the background image, and the analog image with large-aperture monocular field-depth shooting effect is generated.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image processing device and an image depth processing method capable of generating a simulated image with a depth-of-field photographing effect according to a depth map and an original image. Background technique [0002] With the rapid development of technology, the volume of smart phones and general digital cameras is getting smaller and smaller, so as to be convenient for users to carry and take pictures of scenes at any time. Generally speaking, the aperture of smart phones and general digital cameras is usually small, so they can produce clear images of both distant and near scenes. It is worth noting that this advantage of being able to take clear shots of both near and far views also makes it impossible for smartphones or general digital cameras to produce images that can highlight the depth-of-field effect of specific objects. [0003] In contrast, a digital ...
