Embodiment Construction
[0059] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.
[0060]As discussed in the background art, how to adaptively adjust the color temperature of the projection device according to the current environmental conditions plays an important role in improving the visual experience of the user. For this reason, at this stage, the following two methods are mainly used to realize the adaptive adjustment of the color temperature of the projection device: (1) Change the projection light source of the projection device according to the ambient light to compensate for the color temperature deviation (ie, color shift), but this method does not consider the projection surface , The characteristics of the projection light sour...

The present disclosure relates to a projection equipment control method, device, medium and electronic equipment. The method includes: in response to receiving a projection instruction, controlling the projection device to project pure white light onto the projection surface; obtaining the color value of the diffuse reflection light formed by the pure white light and ambient light through diffuse reflection on the projection surface; determining the RGB channel in the projection device according to the color value Gain coefficient; adjust the gain of the RGB channel according to the gain coefficient. Since the color value of the diffuse reflection light on the projection surface includes not only the characteristics of the projection light source of the projection device, but also the characteristics of the projection surface and ambient light, the gain coefficient of the RGB channel in the projection device can be accurately calculated, and then according to the gain The coefficient adjusts the gain of the RGB channel, so as to realize the accurate compensation of the color temperature of the projection light source. In this way, no matter how the ambient light and the projection surface change, the color temperature of the projected picture is always kept within a preset value or range, thereby providing users with the best visual experience.
Description
technical field [0001] The present disclosure relates to the technical field of projection equipment, and in particular, to a control method, device, medium and electronic equipment for 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 the projection plane have a great influence on the vi...
