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: projecting; The control unit 503 is used for: when performing projection, in the illuminable area, reducing the illumination brightness of the overlapping area, where 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 also used for: calibrating the illumination area and the projection area to generate a mapping relationship between the two areas; the calibrated illumination area can...

Abstract

The invention relates to the field of lighting control, in particular to a method and system for controlling lighting during projection. The light control method during projection comprises the following steps: illuminating the illuminable area; performing projection, and reducing the illumination brightness of the overlapping area in the illuminable area, the overlapping area being the illuminable area and the first An overlapping portion of the projected area. By reducing the lighting brightness of the overlapping area between the illuminable area and the projection content area, while maintaining the lighting brightness of other parts of the illuminable area, personalized processing is achieved, which neither affects students' reading of paper materials nor affects students' viewing of projections content.

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, and in order to listen to the teacher's teaching as if they were on the scene, more and more families use projectors to The teaching content is projected on the desktop for learning. However, in the process of learning, students also need to use some notebooks to take notes while listening to the class. Therefore, during the whole process, if the fixed ambient light source brightness illuminates the students' learning desktop, it is impossible to The presentation of the projected content and the real objects (such as books, notebooks, etc.) can achieve a better effect. [0003] For example, when the students are reading books at the beginning, there are some things they don’t...
