Embodiment Construction

[0040] Hereinafter, reference will be made in detail to the embodiments of the present invention, examples of which are shown in the drawings and the following description. Although the present invention has been described in conjunction with exemplary embodiments, it should be understood that this specification is not intended to limit the present invention to these exemplary embodiments. On the contrary, the present invention is not only intended to cover these exemplary embodiments, but also various alternatives, modifications, equivalent forms and other embodiments included in the spirit and scope of the present invention defined by the appended claims.

[0041] The implementation of an embodiment of the present invention is divided into two parts: ranging and blurring processing. Ranging is based on the multi-view point calculation method introduced in the background technology, and the depth data of each feature point in the scene is obtained according to several steps such...

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, in particular to a method of using multi-camera or single-camera multiple imaging technology to calculate depth for scenes in an image, using depth information to calculate blur coefficients, and using filters to perform blur processing on images. The invention also relates to a device implementing such a method. Background technique [0002] 1. Image blur [0003] During sensor imaging, when the object being photographed is within the range of depth of field, the spot on the sensor surface formed by the points on the surface of the object is smaller than the permissible circle of confusion, and the image appears clear; when the object exceeds the range of depth of field, the object is blurred. It is blurring. [0004] Image blur is an important technique in photographic creation, which is usually achieved with large-size sensors and large-aperture lenses. The large-size sensor and large-apertur...
