Color temperature adjustment method, device, computer-readable storage medium, and projection device

Abstract

The disclosure relates to a color temperature adjustment method, device, computer-readable storage medium and projection equipment. The method includes: responding to the color temperature adjustment instruction received by the projection device, and obtaining the target color temperature mode in the color temperature adjustment instruction; if the target color temperature mode is an adaptive mode, obtaining the ambient light diffusely reflected by the projection surface when the projection device is not projecting to the projection surface The first color value of the formed first diffuse reflection light; control the projection device to project pure red light, pure green light, and pure blue light to the projection surface in any order, and obtain the light and The second color value of the second diffuse reflection light formed by the diffuse reflection of ambient light on the projection surface; adjust the color temperature of the projection light source according to the first color value, each second color value and the target color temperature mode. Thus, the color temperature of the projection light source can be adaptively adjusted in combination with the ambient light, the projection surface and the target color temperature mode, and the environmental adaptability of the projection device can be improved so that it can provide users with the best viewing experience.

Description

technical field [0001] The present disclosure relates to the technical field of projection equipment, and in particular, to a color temperature adjustment method, device, computer-readable storage medium, and projection equipment. Background technique [0002] The projection device displays the picture to the user through the principle of diffuse reflection, in which the ambient light will form a diffuse reflection on the projection plane and enter the human eye together with the diffuse reflection of the light projected by the projection device, thus affecting the color temperature of the presented picture. In addition, when users use projection equipment, they usually project images on walls or curtains, and walls or curtains have various materials, microstructures and colors, which will affect the absorption and reflectance of different wavelengths of light. This affects the color temperature of the picture. Therefore, the ambient light and projection plane have a great ...
