Abstract

The invention relates to the field of camera technology, in particular to an illumination processing method and apparatus. A liquid crystal panel with adjustable light transmittance is arranged between a photosensitive sensor and a lens, the light entering from the lens arrives at the photosensitive sensor after penetrating through the liquid crystal panel. The method comprises the following steps: determining a high light area of a first image collected from the photosensitive sensor; and reducing the light transmittance of the pixel points in an adjustment area corresponding to the high light area on the light transmittance. By adoption of the illumination processing method and apparatus provided by the embodiment of the invention, the occurrence of the strong light dispersion phenomenoncan be avoided as much as possible, and the loss of effective information of the image can be avoided as a result.

Description

technical field [0001] The present invention relates to the technical field of imaging, in particular to a method and device for processing light. Background technique [0002] As an important part of the security system, the video surveillance industry has developed by leaps and bounds in recent years. In various video surveillance systems, images of target objects are widely captured by cameras. [0003] At present, the basic structure of cameras used in various video surveillance systems includes: a lens composed of lenses, a photosensitive sensor behind the lens, and a processor for collecting image signals from the photosensitive sensor. The image signal is subjected to image processing. [0004] figure 1 It is a schematic diagram of the structure of a photosensitive sensor. The photosensitive sensor can be regarded as the electronic film of the camera, such as figure 1 As shown, the photosensitive surface of the photosensor is composed of countless small photosens...
