Embodiment Construction

[0050] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0051] This embodiment proposes a single-chip camera processing system supporting face detection, which can implement face detection inside the camera processing chip.

[0052] figure 1 is the block diagram of the system. It includes an imaging device and a camera processing chip connected to it, and the camera processing chip also includes an image processing module connected to the imaging device, an image post-processing module and a face detection module connected to the image processing module, and A built-in storage module connected with the face detection module is stored with a training model library for face detection. The face detection module of the present embodiment also utilizes the external memory interface of the camera processing chip to externally connect one or more external memories, so as to update and expand the training model l...

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...
