Problems solved by technology

[0002] Compared with the display panel, the color temperature of each projection device at the factory is very different due to various factors such as light source and optical path. Even the same batch of projection devices has a large difference in color temperature. Therefore, Even if the color temperature of the projection equipment is adjusted before leaving the factory, the color temperature is inconsistent from the factory to the user's hands
It is unrealistic to manually adjust each projection device after the factory sells it. Therefore, an efficient automatic color temperature adjustment method is needed to improve the user's viewing experience

Embodiment Construction

[0051] 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.

[0052] figure 1 It is a flowchart of a method for controlling a projection device according to an exemplary embodiment. Such as figure 1 As shown, the method includes S101~S103.

[0053] In S101, in response to receiving a projection instruction, acquire target chromaticity coordinates of a projection light source of a projection device.

[0054] In the present disclosure, the method for controlling a projection device can be applied to a projection device, and can also be applied to a terminal (for example, a server, a smart phone, a tablet computer, etc.) connected to the projection device.

[0055] When the user projects a picture through the projectio...

Abstract

The invention relates to a projection equipment control method and device, a medium and electronic equipment. A projection light source of the projection equipment comprises red light, green light, blue light and additional light for improving the projection brightness of the projection equipment. The method comprises the following steps: acquiring a target chromaticity coordinate of a projectionlight source in response to a received projection instruction; determining a gain coefficient of an RGB channel in the projection equipment according to the target chromaticity coordinate and a pre-constructed color lookup table; and adjusting the gain of the RGB channel according to the gain coefficient. Thus, the gain coefficient of the RGB channel can be quickly and directly determined according to the target chromaticity coordinate and the pre-constructed color lookup table, so that the gain of the RGB channel is automatically adjusted according to the gain coefficient, the effect of automatically adjusting the color temperature of the projection equipment in place at a time is achieved, and the impression experience of users is improved.

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] Compared with display panels, due to various factors such as light source and optical path, the color temperature of each projection device at the factory is very different. Even the projection devices of the same batch have great differences in color temperature. Therefore, Even if the color temperature of the projection equipment is adjusted before leaving the factory, the color temperature is inconsistent from the factory to the user's hands. It is unrealistic to manually adjust each projection device after the factory sells it. Therefore, an efficient automatic color temperature adjustment method is needed to improve the user's viewing experience. Contents of the invention [0003] In order to overcome the problems existing in related...
