Embodiment Construction

[0040] Reference will now be made in detail to embodiments of the invention, examples of which are illustrated in the accompanying drawings and described below. While the invention has been described in conjunction with exemplary embodiments, it will be understood that present description is not intended to limit the invention to those exemplary embodiments. On the contrary, the invention is intended to cover not only the exemplary embodiments, but also various alternatives, modifications, equivalents and other embodiments included within the spirit and scope of the invention as defined by the appended claims.

[0041] The implementation of an embodiment of the present invention is divided into two parts: ranging and blurring processing. According to the multi-viewpoint calculation method introduced in the background technology, distance measurement obtains the depth data of each feature point in the scene according to several steps such as shooting, matching, and depth calcul...

Abstract

The invention relates to a method and a device for carrying out blurring processing on images. The method for carrying out blurring processing on the images comprises the following steps: shooting, namely, using one or more imaging device(s) to acquire a plurality of source images at different angles of view aiming at one scene; carrying out depth calculation, namely, calculating the source images to obtain the depth information of the scene; carrying out image processing, namely, carrying out image blurring processing on one of the source images by utilizing the depth information. After the method and the device are adopted, the images with a blurring effect can be realized on a small-sized device.

Description

technical field [0001] The present invention relates to the field of image processing, and in particular to a method for calculating the depth of a scene in an image by using multi-camera or single-camera multiple imaging technology, using the depth information to calculate a blur coefficient, and using a filter to perform blur processing on the image. The invention also relates to a device for carrying out this method. Background technique [0002] 1. Image blurring [0003] When the sensor is imaging, when the object to be photographed is within the depth of field range, the diffuse spots formed by the points on the surface of the object on the sensor surface are smaller than the permissible diffusion circle, and the image appears clear; when the object is beyond the depth of field range, the object appears blurred, which is called It is virtualization. [0004] Image blurring is an important technique in photography creation, which is usually achieved with large-size s...
