Specific embodiment
It is with reference to the accompanying drawing and specific real in order to make those skilled in the art more fully understand technical solution of the present invention
Applying example, the present invention is described in further detail.
Embodiment 1
As shown in Figure 1, the method is applied to projector controller, described the present embodiment provides a kind of method for controlling projection
Method includes:
S1: control shooting module shooting includes the perspective plane picture A of view field, does not include in the perspective plane picture A
Projection image；
S2: the corresponding chromaticity coordinates of view field in the perspective plane picture A is obtained；
S3: according to the electricity of the corresponding chromaticity coordinates adjustment projection module output of the view field in the perspective plane picture A
Source configuration；
S4: control projection module is according to power configuration adjusted by picture projection to be projected to view field.
In the present embodiment, step S1 may include:
S11: control projection module projects a normal pictures to perspective plane；
S12: control shooting module shooting includes the perspective plane picture B of the normal pictures；
S13: pixel coordinate range P of the normal pictures in the picture B of perspective plane is obtained；
S14: control shooting module shooting includes the perspective plane picture A of view field, does not include in the perspective plane picture A
Projection image, wherein the perspective plane picture A is identical as the pixel coordinate range of the perspective plane picture B, the perspective plane figure
View field in piece A is the corresponding region the pixel coordinate range P.It here, does not include the perspective plane picture A of projection image
Refer to that perspective plane picture A is exactly the corresponding picture in perspective plane itself, that is to say, that the color regime of perspective plane picture A is exactly to project
The color regime of the color regime in face itself, perspective plane picture A at this time is not influenced by the projection image of projection module.
Preferably, the step for view field that obtains in the perspective plane picture A corresponding chromaticity coordinates, that is, walk
Rapid S2, comprising:
S21: gamut regions division is carried out to the view field in the perspective plane picture got；
S22: judging whether the view field in the perspective plane picture A only includes a gamut regions, if the throwing
View field in the picture A of shadow face only includes a gamut regions, then obtains the chromaticity coordinates of the gamut regions, if the projection
View field in the picture A of face includes multiple gamut regions, then obtains the chromaticity coordinates of each gamut regions respectively.Wherein, if
Only one gamut regions indicates that the background colour of view field indicates view field if there is multiple gamut regions for pure color
Background colour is complex colors.
What needs to be explained here is that the shooting module in the present embodiment can be the included camera of projection module, it can also
To be individual photographic device, probe or wide-angle lens head etc., can be closed in the ray machine of projection module when shooting perspective plane picture A
Shooting when closing avoids the influence of projection module light, and for perspective plane, for example metope, some projection face colors are more equal
The color of view field in even or perspective plane is relatively uniform, then view field in the perspective plane picture A in the present embodiment
It is corresponding with regard to only one gamut regions, correspondingly, also with regard to only one chromaticity coordinates, according to the available region of chromaticity coordinates
Dominant wavelength and colour temperature, but the uneven color of some view fields, such as left one side of something are rice white, and right one side of something is yellow, this
View field when a just corresponds to two gamut regions, correspondingly, also just includes two chromaticity coordinates, needs to carry out color respectively
(power configuration of the adjustment projection module output described below, makes the corresponding region of the output white screen of projection module for compensation
Colour temperature is preset color temperature after mixing with the colour temperature of each gamut regions), the present embodiment can improve projection image well
Display effect in view field, greatlys improve user experience.It is further to note that passing through bat in the present embodiment
After taking the photograph the view field that module obtains in projection image A, by figure in the CPU processor (such as MSTAR chip) of projection control
As the corresponding chromaticity coordinates of view field in the perspective plane picture A, the adjustment module of CPU processor is calculated in processing module
The power configuration that projection module needs to export is calculated according to the corresponding chromaticity coordinates of view field in the perspective plane picture A
Afterwards, adjustment module adjust under the control of cpu projection module output power configuration, i.e., change RGB electric current or RGBY electric current or
The duty ratio of light source realizes the control of the colour temperature to the output white screen of projection module, reaches good display effect.Here, it throws
The colour temperature of the output white screen of shadow module can refer to the colour temperature of the picture to be projected of projection module output.
Preferably, the corresponding chromaticity coordinates of view field according in the perspective plane picture A adjusts projection module

S323: the power configuration of adjustment projection module output, so that the color of the corresponding region of the output white screen of projection module
The warm colour temperature with each gamut regions is preset color temperature after mixing.
Here, preset color temperature can be the colour temperature of the pre-set colour temperature of user or projection control default, such as
User likes warm tones, then colour temperature may be preset as to 6300K, and corresponding chromaticity coordinates is (0.315,0.33), is denoted as a, if with
Cool tone is liked at family, then colour temperature may be preset as to 10000K, and corresponding chromaticity coordinates is (0.27,0.341), b is denoted as, if user
Non-selected, system default colour temperature is 8200K, and corresponding chromaticity coordinates is (0.29,0.31), is denoted as c；Certainly, user can also basis
Demand presets other colour temperatures and obtains corresponding chromaticity coordinates.When implementing the present embodiment, if user preset colour temperature is
6300K, presetting chromaticity coordinates is a, and projection control gets a chromaticity coordinates d of view field, and ambient brightness Ld is needed at this time
The corresponding green electric current of RGB electric current in adjustment module adjustment projection module or red electric current or blue current are controlled, makes to throw
The chromaticity coordinates of the output white screen of shadow module be e (since d and a are known chromaticity coordinates, projection control module by calculate or this
The empirical value prestored knows chromaticity coordinates a to be obtained, and chromaticity coordinates d can be mixed with e), brightness Le, projection module is defeated at this time
