Problems solved by technology

[0004] However, in the above-mentioned method and device for adjusting the size of the projection display screen in the prior art, the size and brightness of the projection display screen are adjusted according to the size of the use environment, and the intensity of the ambient light is not considered to affect the projection display screen. The size of the screen, so the size of the projected display screen cannot be changed according to the intensity of ambient light
In addition, the change of the projection display screen in the above-mentioned projector is set by the projection manufacturer in the projection device, and the user cannot change the corresponding parameters, and cannot set the customary viewing mode
Since different users have different viewing habits, and there is no unified standard, the projection equipment in the prior art generally does not consider the user's habits, resulting in different users not being able to obtain an optimized personal experience

Abstract

The invention discloses a method and a device for adjusting a projection display screen size of a projector. In the method and the device for adjusting the projection display screen provided by the invention, the present environmental light brightness of the present service environment are obtained in real time; and then the size of the present projection display screen is adjusted in real time according to the correspondence of the obtained present environmental light brightness and the predetermined environmental light brightness to the size of the projection display screen. The method and the device for adjusting the projection display screen provided in the invention are capable of changing the projection display screen size according to the intensity of the environmental light.

Description

technical field [0001] The invention relates to the adjustment technology of projection display equipment, in particular to a method and device for adjusting the size of the projection display screen of the projection equipment. Background technique [0002] In most existing projection device products, the size of the projected display screen of the projection device can generally be adjusted. For example, in the prior art, a projector that adjusts the screen size and brightness according to the size of the environment is proposed. In the projector, the distance from the projector to the front of the projector and the distance from the projector to the rear of the projector can be detected, and based on the distance from the projector to the front of the projector and the distance from the projector to the The distance to the rear of the projector adjusts the brightness of the projector. [0003] Although the projection devices in the prior art can display large-sized imag...
