specific Embodiment approach

[0086] see Figure 5 , in this embodiment, a specific implementation of a lighting control system 500 during projection is as follows:

[0087] A lighting control system 500 during projection, comprising: a projector 501, an illumination array 502, and a control unit 503; the illumination array 502 is used for: illuminating an illuminable area; the projector 501 is used for: projection; The control unit 503 is configured to: when performing projection, in the illuminable area, reduce the illumination brightness of the overlapping area, the overlapping area is the overlapping part of the illuminable area and the first projection area.

[0088] Further, the control unit 503 is further configured to: keep the illumination brightness of the non-overlapping area unchanged.

[0089] Further, the control unit 503 is further configured to: calibrate the lighting area and the projection area to generate a mapping relationship between the positions of the two areas; the calibrated ligh...

Abstract

The invention relates to the field of lamplight control, particularly to a lamplight control method and system during projection. The lamplight control method during projection comprises the followingsteps: illuminating an illuminable area; and projecting, and reducing the illumination brightness of an overlapping region in the illuminable region, wherein the overlapping region is the overlappingpart of the illuminable region and the first projection region. By reducing the illumination brightness of the overlapped region part of the illuminable region and the projection content region, theillumination brightness of other parts of the illuminable region is kept, personalized processing is achieved, reading of paper edition materials by students is not affected, and watching of projection content by the students is not affected.

Description

technical field [0001] The invention relates to the field of lighting control, in particular to a method and system for controlling lighting during projection. Background technique [0002] With the popularization of online distance teaching, more and more people choose to study online courses at home. The lecture content is projected onto the desktop for learning. However, during the learning process, students also need to use some notebooks to take notes while listening to the lectures. Therefore, during the whole process, if the brightness of the fixed ambient light source illuminates the student's learning desktop, it will not be possible. Thus, the presentation of the projected content and the real objects (such as books, notebooks, etc.) can achieve a better effect. [0003] For example, students are reading at the beginning, and there are some things they don’t understand in the process. At this time, the projection and playback of relevant materials is carried out. ...
