Embodiment Construction

[0040] It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0041] Embodiments of the present application provide a method, device, medium, and computer program product for adjusting the brightness of a projector. The projection image of the projection area is obtained, and the scaling factor information of the projection content in the projection image is determined; and the scaling factor information is determined according to the scaling factor information. Brightness adjustment information of the projection content; according to the brightness adjustment information, the brightness of each display area of ​​the projection content is adjusted, so that the display effect of the projection content in each of the display areas is consistent. After projecting the projected content to the projected area, the present application takes a projected image of the ...

Abstract

The invention discloses a projector brightness adjusting method and device, a medium and a computer program product, and the method comprises the steps: obtaining a projection image of a projection region, and determining the zoom coefficient information of projection content in the projection image; determining brightness adjustment information of the projection content according to the zoom coefficient information; and performing brightness adjustment on each display area of the projection content according to the brightness adjustment information, so that the display effects of the projection content in each display area are consistent. After the projection content is projected to the projection area, the projection image is shot for the projection area, the zoom coefficient information of the projection content in the projection image is determined, and finally the brightness of the projection content is adjusted through the brightness adjustment information determined by adjusting the zoom coefficient information, therefore, the display effect of the projection content in each display area in the projection area is consistent, the brightness of the projection content watched by the user is smooth, and the impression of the user on the projection content is improved.

Description

technical field [0001] The present application relates to the field of projection technology, and in particular to a method, device, medium and computer program product for adjusting brightness of a projector. Background technique [0002] With the rapid development of economy and technology and the improvement of people's living standards, smart home devices have attracted widespread attention. At present, many smart home devices are equipped with projectors, but the current projectors consume a lot of power and run for a long time. It will lead to excessive power consumption, generate more hot spots, and reduce the life of the projector. [0003] When the projector is projecting on non-parallel planes, if the projection lamps use the same brightness for projection, because the distance between the projection lamp and the projection point is different, the brightness display of the projected content on the non-parallel planes will be different, which will affect the user's ...
