Abstract

The invention relates to a videography processing method and a videography processing system supporting face detection. One frame image that is obtained by videography is processed through face detection, and whether a face exists in the frame image is determined according to a detecting result; if the face exists in the frame image, image characteristic information of a face area is acquired, and one or more image control parameters are adjusted by taking the image characteristic information of the face area as a basis or one of the bases; correspondingly, the videography processing system comprises an imaging device and a camera processing chip connected with the imaging device; and the camera processing chip comprises an image processing module, an image post-processing module, a face detecting module and a memory module which saves a training model library used for face detection. The videography processing method and the videography processing system can support the videography processing for face detection, so as to achieve better videography effect.

Description

technical field

[0001] The invention relates to image processing technology, in particular to a camera processing system and method. Background technique

[0002] In cameras and surveillance systems, human faces are usually areas of interest, so it is always desirable to obtain images with clearer human face areas and better imaging quality.

[0003] However, due to the complexity of face detection, the existing camera processing chips do not include the face detection function, so that the face area information cannot be used to adjust relevant image parameters, thereby obtaining better image quality or effect. Contents of the invention

[0004] The technical problem to be solved by the present invention is to provide a camera processing system and method supporting face detection, which can realize camera processing supporting face detection and obtain better camera effects.

[0005] In order to solve the above problems, the present invention provides a camera processin...
