Embodiment Construction

[0047] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the present disclosure will be described in further detail below in conjunction with the implementation manners and accompanying drawings. Here, the exemplary embodiments of the present disclosure and their descriptions are used to explain the present disclosure, but not to limit the present disclosure.

[0048] Before describing the embodiments of the present disclosure in detail, firstly, the content involved in the embodiments of the present disclosure is introduced as follows:

[0049] Three primary colors: Most colors in nature can be obtained by mixing three primary colors in a certain proportion; conversely, any color can be decomposed into three primary colors. The proportions of the three primary colors are different, and the colors obtained by mixing are also different. And the three primary colors are independent of each other, and any one of them cannot be pr...

Abstract

The invention provides a photographing method and device, and belongs to the technical field of photography. The method comprises the following steps: when a camera is started, obtaining a specified color temperature value of a current light source through a configured color temperature sensor; determining a specified reference scale corresponding to the specified color temperature value according to a pre-established mapping relation of the color temperature value and the reference scale; determining white balance matched with the specified reference scale, wherein the white balance is used for compensating the specified reference scale; and adjusting the color of a photographed object according to the white balance, and generating an image according to the adjusted color of the object. According to the photographing method provided by the invention, the color temperature sensor is configured, and the mapping relation of the color temperature value and the reference scale is pre-established, so that when the camera is started, the matched white balance can be obtained quickly, and when adjusting the color of the photographed object according to the white balance, a color cast phenomenon can be avoided, when the camera is started.

Description

technical field [0001] The present disclosure relates to the technical field of photographing, in particular to a photographing method and device. Background technique [0002] The color of the light reflected by the object is determined according to the color of the light emitted by the light source. For different light sources, the color of the light emitted is different, which will cause the color of the light reflected by the object to be different. Then, when using a video camera to shoot an object, it is likely that the object will have a color cast due to the influence of the light source. For example, the object shot under indoor tungsten light will be yellowish. [0003] In order to avoid color cast, the camera can adjust the color of the captured object according to the white balance, so that the image generated after the color adjustment can reflect the real color of the object. Among them, the white balance can be expressed by the ratio between the gain coeffici...
