Projection control method and projection device

Abstract

The invention discloses a projection control method and projection equipment. The projection control method disclosed by the invention comprises the following steps: acquiring a first screen image on a projection area while projecting a first projection image to the projection area at a first moment; according to the first projection image and the first screen image, determining difference images; and according to the difference images, projecting a second projection image through adjustment to the projection area at a second moment. The projection equipment disclosed by the invention comprises a projection unit, a shooting unit and an image processing unit. According to the projection control method and the projection equipment disclosed by the invention, the coverage area of a user positioned between the projection equipment and a screen can be acquired in real time, and the area is processed during broadcasting, so that the problem that projected lamplight and screens can be projected onto the body of the user is solved.

Description

technical field [0001] The present invention relates to the technical field of image processing, and in particular, to a projection control method and a projection device. Background technique [0002] At present, the application of projection equipment is becoming more and more extensive, especially in schools, enterprises and other occasions that need to be explained, the demand for projectors and projection TVs has increased significantly. [0003] Taking the projector as an example, during the projection process, in order to facilitate the explanation, the speaker will stand between the projector and the screen. The picture will be projected on the speaker. When the speaker performs the demonstration action, because the picture and light on the speaker are integrated with the screen, the audience will not be able to see the speaker and the demonstration action. In addition, because the light projected by the projector and the light on the screen are very strong, when th...

Problems solved by technology

[0003] Taking the projector as an example, during the projection process, for the convenience of explanation, the speaker will stand between the projector and the screen. The screen will be projected onto the speaker. When the speaker is demonstrating, the audience will not be able to see the speaker and his demonstration because the screen and lights on the speaker are integrated with the screen.

In addition, because the light projected by the projector and the light on the screen are very strong, when the speaker observes the reaction of the audience, it will affect the speaker's vision, and if things go on like this, it will damage the speaker's eyes

[0004] However, in the prior art, there is no method and equipment that can well solve this problem

Therefore, aiming at the problem that the light and picture projected by the existing projection equipment will be projected on the user located between the projection equipment and the screen, which will affect the vision of the audience and the user and cause harm to the user, it is necessary to provide a Projection control method and projection device for improving visual effect and viewing experience
