Abstract

Embodiments of the present invention provide a method, device, and electronic equipment for adjusting photometry. The method includes: calculating the first brightness value of an image in YUV space; converting the image from RGB space to HSI space; determining the image Hue weight and saturation weight corresponding to the HSI space; according to the hue weight and saturation weight and the first brightness value of the image in the YUV space, calculate the second brightness value of the image in the YUV space; according to the The comparison result of the second brightness value of the image in the YUV space and the target brightness is used to adjust the light metering parameters of the next frame of image. The method pre-adjusts the light metering parameters of the next frame of image before shooting, so that the brightness of the photo taken by the electronic device is closer to the brightness seen by the naked eye, thereby improving user experience.

Description

technical field [0001] The present invention relates to the field of data processing, in particular to a method, device and electronic equipment for adjusting photometry. Background technique [0002] With the development of science and technology, people are more and more fond of taking pictures with electronic devices such as cameras or mobile phones. However, the photo taking effect of many electronic devices is not ideal at present. For example, the brightness of photos taken by electronic devices such as cameras or mobile phones is inconsistent with the brightness seen by the naked eye, which makes the user experience poor. Contents of the invention [0003] In view of this, the purpose of the embodiments of the present invention is to provide a method, device and electronic equipment for adjusting light metering, so as to solve the above problems. [0004] In order to achieve the above object, the technical solution adopted in the embodiment of the present invention...
