Embodiment Construction

[0036] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0037] It can be understood that the terms "first", "second" and the like used in this application may be used to describe various elements herein, but these elements are not limited by these terms. These terms are only used to distinguish one element from another element. For example, a first type of camera could be termed a second type of camera, and, similarly, a second type of camera could be termed a first type of camera, without departing from the scope of the present application. Both the first type camera and the second type camera are cameras, but they are not th...

Abstract

The present application relates to an exposure processing method, device, electronic equipment, and computer-readable storage medium. The method includes: controlling each of the at least two first-type cameras to shoot the same shooting scene, and obtain a corresponding original image respectively; aligning all the original images obtained by shooting, and determining all An overlapping area in the original image is used as a first photometry area; performing photometry processing on the first photometry area to obtain a first brightness parameter value, and determining the at least two The exposure parameter value of the first-type camera; controlling the at least two first-type cameras to perform exposure according to the obtained exposure parameter value. The above exposure processing method, device, electronic equipment, and computer-readable storage medium can improve the accuracy of exposure processing.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to an exposure processing method, device, electronic equipment, and computer-readable storage medium. Background technique [0002] A camera is generally composed of a lens and an image sensor. The lens can collect light in the environment, and the image sensor converts the light into an electrical signal. In the process of converting light into electrical signals, the image sensor perceives the light for different periods of time, and the energy of the received light is also different, so the strength of the converted electrical signals is also different. [0003] The process of the image sensor sensing light is exposure, the longer the exposure time, the more energy of the received light. However, if the exposure time is too long, the generated image may be too bright due to overexposure; while the exposure time is too short, the generated image may be too dark...
