Embodiment Construction

[0074] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0075] The present invention mainly aims at the problem that in the prior art, when the image is blurred by Gaussian blur technology, the connection boundary between the foreground area and the background area in the processed image is not clear, and ghosting occurs, and a method is proposed. Image blurring method.

[0076] The image processing method proposed by the present invention first acquires the depth of field image to be processed, then determines the foreground area and the background area in the acquired depth of field...

Abstract

The invention provides an image blurring method, a device and a camera terminal. The method includes the following steps: acquiring a depth image to be processed; determining a foreground area and a background area in the depth image; and if determining that a target filtering area corresponding to pixels to be blurred contains pixels of the foreground area during blurring of the background area, adjusting the weights of the pixels in the target filtering area. By adjusting the weights of the pixels in the target filtering area containing pixels of the foreground area, the boundary between the foreground area and the background area of the image is clear after blurring, the blurred edge of the background area is protected, the overall quality of the image is improved, and the user experience is enhanced.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image blurring processing method, device and shooting terminal. Background technique [0002] At present, when processing a captured image, in order to highlight the main part of the image, the background part of the image can usually be blurred. For example, Gaussian blur technology can be used to blur the background part of the image to preserve the main part. [0003] Specifically, Gaussian blur refers to a blurring algorithm based on distance as a weight. It usually counts the pixel values ​​​​of a point to be blurred and surrounding adjacent points, and uses a weighted average calculation method to obtain the pixel points to be blurred. corresponding pixel value. However, the inventors found that after using the Gaussian blur technology to process the image, the edges where the main part and the background part in the entire image are not clear and have...
