Abstract

The invention discloses a control method based on face area exposure. The system comprises a face region detection module, a face brightness acquisition module, a face weight distribution module and aface brightness adjustment module, and specifically comprises the following steps of 101) obtaining a face region coordinate, 102) processing face brightness, 103) realizing weight distribution and 104) adjusting the face brightness. According to the control method based on face area exposure, the problems that the face is too bright and too dark and is greatly influenced by the environment are solved, and intelligent exposure is carried out on a multi-face place.

Description

technical field [0001] The present invention relates to the technical field of image exposure processing, and more specifically, it relates to a control method based on face area exposure. Background technique [0002] At present, there are certain shortcomings in the face-based exposure method in image processing in the industry: for example, when the face detection algorithm loses a face, the exposure flickers; under special lighting conditions, the exposure of the face area is not normal; there are multiple faces in the picture The area cannot take into account most of the faces; the face area is too bright, too dark and other problems. Contents of the invention [0003] The present invention overcomes the deficiencies of the prior art, and provides a face area-based exposure method that solves the problems that the face is too bright, the face is too dark, and is greatly affected by the environment, and performs intelligent exposure for places with multiple faces. Con...
