Abstract

An embodiment of the present invention provides an automatic exposure method and device for an imaging device, which acquires the brightness information of each image block in the collected image, the current exposure time of the imaging device, and the target brightness information, and determines the brightness information of each image block according to the brightness information of each image block The exposure information in the image provides the current brightness information of the area. According to the target brightness information, current brightness information and current exposure time, the target exposure time of the camera equipment is calculated, and the current exposure time is adjusted as the target exposure time. Based on the brightness information of each image block in the image, the current brightness information of the exposure information providing area in the image can be determined in real time. The exposure information providing area is the area within the field of view of the image. After calculation, the camera equipment can be adaptively adjusted The exposure time is set so that the exposure time can ensure the exposure effect of the imaging device under the current brightness of the area where the exposure information is provided, thereby improving the imaging effect of the imaging device.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an automatic exposure method and device for an imaging device. Background technique [0002] Camera equipment in special application fields such as endoscopes is different from ordinary camera equipment. Because it focuses on targets within a fixed area, it usually uses a lens with a fixed field of view. Only the area within the middle field of view is imaged, while the area outside the field of view Area is blocked. [0003] Currently, the focal length of the lens of these imaging devices is usually fixed, and therefore, the imaging field of view area is also fixed. If the lens is replaced with a zoom lens, the focal length of the lens changes, or another fixed-focus lens with a different focal length is replaced, the imaging field of view area will change accordingly. However, the exposure parameters of the camera equipment will not be automatically adjusted as the f...
