A regional color adaptive projection device and method

Abstract

The invention relates to the technical field of projection, in particular to a regional color adaptive projecting apparatus and method allowing the color of a picture projected to a wall or wallpaper to never shift and applicable to families or office places having nonwhite color and wallpapers. The apparatus comprising a projector is characterized in that a photographic device is mounted on the projector, and the projector is further provided with a differential light analysis module, a chromatographic control module, a projector digital optical processor and a projector digital imaging module. By simply scanning a wall, each colored wall of each room in a family or a club and even a roof of a bedroom can be given a picture with no color shift, large-screen viewing, surfing, working and gaming is available to people anytime and anywhere, curtain installation cost and wall modification cost are saved, and television screens cause less radiation harm to human eyes, especially eyes of infants.

Description

Technical field [0001] The present invention relates to the field of projection technology, and in particular to a regional color adaptive projection device that can prevent a picture projected on a wall or wallpaper from producing a color cast, and is suitable for use in non-white homes or offices where wallpaper is pasted. method. Background technique [0002] At present, the technology of projectors is changing with each passing day, and breakthroughs have been made in terms of volume, light source life, clarity, and power consumption. Compared with traditional LCD TVs, home theaters, meeting rooms, and classrooms composed of projectors have no radiation and no radiation It has the advantages of flickering, large viewing area, mobile and portable, and can be connected to various multimedia entertainment devices such as TV set-top boxes, computers, game consoles, and the time to replace traditional TV sets is gradually coming. However, so far the scope of application of projec...

Problems solved by technology

However, so far, projectors are still used in clubs, colleges and offices, and the pace of replacing TVs is still slow

One of the main reasons restricting its application is that the application of the projector needs to hoist the projection screen or leave a white wall as the image carrier to watch, otherwise, after putting it on the colored wall, the image will have serious damage due to the influence of the background color of the wall. Color cast phenomenon, it is difficult to take into account the beauty of home and office layout and the visual effect brought by projection

At the same time, after the installation of the ceiling-mounted screen is completed, the mobile and portable advantages of the projector are no longer obvious, which hinders the projector from entering more market fields
