Description
Technical field
The present invention relates to projection art, more particularly to a kind of picture that can make to be incident upon on wall or wallpaper is not produced
Raw colour cast, the adaptive projection arrangement of a kind of regional color be adapted in non-white, thering is the family of wallpaper or office space to use
And method.
Background technology
At present, the technology of projector is maked rapid progress, and constantly obtains prominent in terms of volume, light source life, definition, power consumption
It is broken, compared with traditional liquid crystal TV set, using the home theater, meeting room, classroom of projection composition have it is radiationless, do not dodge
The advantages such as bright, effective area is big, Mobile portable, and all kinds of multimedia joys such as TV set-top box, computer, game machine can be connected
Happy equipment, the opportunity of substitution conventional television gradually arrives.But, so far projector applications scope be still club, universities and colleges and
Office space, replaces the paces of TV still slow.The one of the main reasons for restricting its application is that the application needs of projector are hung
Filling projection screen or reserving white wall could watch as picture carrier, after otherwise being delivered on colored metope, due to metope
The influence picture of background color can produce serious colour cast phenomenon, come it is difficult to take into account family, the attractive in appearance and projection zone of office space layout
Visual effect.Meanwhile, complete after lifting curtain installation, the Mobile portable advantage of projector also no longer substantially, hinders projection
Into more market segments.
Using reflection type projection technology as main flow in current field of projector, on the digital imagery chip of reflection type projection technology
Highest has 4096 × 2160 small reflectors, and each mirror represents a pixel, and each small reflector has independent control
The switching capability of light.The angle of small reflector reflection light is adjusted by vision signal control, vision signal by Digital Light Processor
Make to control the time of small reflector open and close light path, there is certain characteristic and advantage for the regulation and control of light source, color.
The content of the invention
There is provided one for the drawbacks of must being delivered instant invention overcomes existing projector on projection screen or white wall
Kind can adaptively it be projected in colored metope viewing not colour cast, the region projection color for greatly improving the use scope of projector equipment
Device and method.
The present invention is achieved through the following technical solutions：
A kind of adaptive projection arrangement of regional color, including projection arrangement, it is characterised in that：Installed on the projection arrangement
There is filming apparatus, the projection arrangement is also equipped with equation of light analysis module, chromatogram control module, projector's digital light processing devices
And projector's digital imagery module.
A kind of adaptive projecting method of region projection color, it is characterised in that：Comprise the following specific steps that：
（1）Shoot digital photos：Projection arrangement projects white light beam is to the metope for carrying color lump, and filming apparatus is to projection wall
The shooting area in face take pictures being formed with the digital photos of certain pixel；
（2）Determine view field：By step（1）The digital photos of shooting are right in units of pixel by equation of light analysis module
Its color is scanned, using tolerance between each pixel, the brighter part of color in digital photos is identified, by this
Part is identified as view field, the view field is cut out, and store the pixel value in the view field corresponding to color.
（3）Adjust vision signal：According to the above-mentioned recognition result to digital photos, chromatogram control module is with digital photos
The pixel of view field is that unit sends vision signal adjust instruction to Digital Light Processor, to digital imagery mould in projection arrangement
The color that block is projected is limited, reduce color lump at same color color output, now view field project i.e.
For the image frame of not colour cast.
The beneficial effects of the invention are as follows：By to the simple scanning of wall, making each room in family, club, it is each
The roof in wall of the face with color even bedroom can deliver the image of not colour cast, be convenient for people to enjoy big screen sight whenever and wherever possible
Shadow, online, office, game, have saved curtain installation, metope improvement cost, and it is special to people's eyes to reduce video screen
It is the radiation injury of infant's eyes.
Brief description of the drawings
The present invention is further illustrated below in conjunction with the accompanying drawings.
Structural representation when accompanying drawing 1 works for a kind of adaptive projection arrangement of region projection color of the invention；
Accompanying drawing 2 is a kind of workflow diagram of the adaptive projection arrangement of region projection color of the invention；
In figure, 1 projection arrangement, 2 filming apparatus, 3 metopes, 4 view fields, 5 shooting areas, 6 color lumps.
Embodiment
The present invention is further illustrated with specific embodiment below in conjunction with the accompanying drawings, but is not limited to the model of the present invention
Enclose.
Filming apparatus 2 is installed on a kind of adaptive projection arrangement of regional color, including projection arrangement 1, projection arrangement 1,
The projection arrangement 1 is also equipped with equation of light analysis module, chromatogram control module, projector's digital light processing devices and projector
Digital imagery module.The device is not limited by place, saves curtain installation cost and metope improvement cost, its specific projecting method
Comprise the following steps：
（1）Shoot digital photos：Open projection arrangement 1 and filming apparatus 2 is at working condition, projection arrangement 1 is thrown
White light beam is penetrated to the metope 3 for carrying color lump 6, the shooting area 5 of 2 pairs of projection metopes 3 of filming apparatus take pictures being formed with one
The digital photos of fixation element.
（2）Determine view field：By step（1）The digital photos of shooting are right in units of pixel by equation of light analysis module
Its color is scanned, using tolerance between each pixel, the brighter part of color in digital photos is identified, by this
Part is identified as view field 4, the view field 4 is cut out, and store the pixel in the view field 4 corresponding to color
Value.
（3）Adjust vision signal：According to the above-mentioned recognition result to digital photos, chromatogram control module is with digital photos
The pixel of view field be unit send vision signal adjust instruction to projector's digital light processing devices, to projector numeral into
The color gone out as module projects is limited, and is reduced the color at color lump 6 with its same color and is exported, receives general in projection arrangement
During logical vision signal, because the instruction of chromatogram control module is first, the picture projected is set no longer to be sent out in restricted pixel
Confined color is sent, not because color overlaid produces colour cast when the picture projected is shown on colored wall, i.e., is now being thrown
What shadow zone domain was projected is the image frame of not colour cast.
By taking 1024 × 768 pixel opaque projectors as an example, 1024 × 768 are had in projector's digital imagery module
Small reflector, each mirror represents a pixel, and each small reflector has the ability of independent control light, passes through numeral
Light processing module sends the time of instruction control small reflector open and close light path, produces the image of different brightness and gray scale.To adjust
Digital light processing devices send the time of instruction control small reflector open and close light path afterwards, make wall or the coloured projection of wallpaper
The small reflector reduction or no longer reflection and the color of the same color of color lump 6 of corresponding pixel points position when region 4 is projected at color lump 6
Coloured silk, such as：Color lump 6 is red, is the image redfree being incident upon in the region of color lump 6 using the effect of the device, makes pattern colour
Coloured silk will not cause colour cast due to red overlay.
