Problems solved by technology

However, the limitation of the automatic light metering function is that when using image capture tools to take photos or record videos with people as the target, due to the influence of real scene lighting, automatic light metering can still easily lead to overexposure of human faces in the image , resulting in the loss of face information in the image, and the face image shooting effect is not good

Abstract

The present invention provides a photometry processing method, the method comprising: face detection is performed on an image output by a camera; if a face area is detected in the image, the brightness value of the face area is calculated; The mapping relationship between the brightness value interval and the adjustment amount of the exposure compensation parameter determines the adjustment amount of the exposure compensation parameter corresponding to the brightness value interval to which the brightness value belongs; determines the exposure compensation parameter according to the adjustment amount; according to the exposure compensation parameter to set the exposure compensation for the camera. This method can effectively overcome the problem of face overexposure caused by the influence of real scene lighting on the output image of the camera, ensure that the face is displayed at normal brightness in the image, and the face information in the image is not lost, which can significantly improve the shooting effect of the face image.

Description

technical field [0001] The present invention relates to the technical field of image capture, and in particular, the present invention relates to a photometric processing method, device, computer-readable storage medium and equipment. Background technique [0002] With the rapid development of hardware technology, image capture tools that can be used for image capture can be seen everywhere, such as cameras, video recorders, smart terminals equipped with cameras, and the like. For image capture tools, it captures the dynamic range of light brightness, that is, the larger the ratio of the maximum and minimum brightness values ​​in the output image, the richer the details of the bright part of the image can be presented. However, compared with the light brightness in the natural environment, the dynamic range of the image capture tool that can capture the light brightness is limited, so it is necessary to rely on its metering function to make the correct exposure compensation ...
