Abstract

The invention discloses a color temperature detection method, which comprises the following steps: dividing an image into a plurality of regions; processing the image to identify a light source of each region; calculating a color temperature evaluation value and a weight of each region according to the light source; and calculating the equivalent color temperature evaluation value of the image according to the color temperature evaluation value and the weight. The invention further discloses a color temperature detection device, a computer readable storage medium and computer equipment. According to the technical scheme of the color temperature detection device, the computer readable storage medium and the computer equipment, the image is divided into regions, and the light source of eachregion is identified. After that, the color temperature evaluation value and the weight of each region are determined according to the light source of the region. Finally, the equivalent color temperature evaluation value of the image is determined according to the color temperature evaluation value and the weight of each region. That means, the execution of the white balance treatment is not separately dependent on the color temperature of a main light source. As a result, the jumping change of the color tone of a preview image caused by the switching of the main light source during the lensshaking process can be avoided. The white balance stability is enhanced, and the user experience is improved.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular, to a color temperature detection method, a color temperature detection device, a computer-readable storage medium, and a computer device. Background technique [0002] In a multi-light source scenario, when using the specular reflection method to correct the white balance of an image, one light source will be selected from multiple light sources as the main light source, and white balance compensation will be performed based on the color of the main light source. However, when the lens is tilted or moved to cause a slight angle change, the selected main light source will frequently change, which in turn causes the color tone of the image after white balance correction to keep jumping, which affects the user experience. SUMMARY OF THE INVENTION [0003] Embodiments of the present application provide a color temperature detection method, a color temperature d...
