Specific embodiment
Hereinafter, referring to the drawings embodiments of the present invention are described in detail.Should illustrate, the present invention
Do not limited by embodiment shown below.The example that these are implemented only illustrates, and the present invention is permissible
Implemented in the way of have passed through the knowledge based on those skilled in the art and carrying out various changes, improvement.Should
Give explanation, in the present description and drawings, symbol identical element represents mutually the same element.
Figure 1 illustrates an example of the white balance adjustment system of present embodiment.Present embodiment
White balance adjustment system possesses white balance adjustment device 91 and detector 92.Detector 92 measures display
93 colourity and brightness.
Display 93 is the display carrying out object of blank level adjustment.Display 93 is can be to every kind of
The display of the voltage of luminous color control illuminant color, the e.g. organic el display of RGB type.
White balance adjustment device 91 possesses information treatment part 11 and storage part 12.Information treatment part 11 has
There is the curve export function that chroma control function, white balance writing function and voltage are with respect to white brightness.
White balance adjustment device 91 can play chroma control function, white balance record work(by making computer
Can realize with respect to the curve export function of white brightness with voltage.So, white balance adjustment device 91
Interior CPU (Central Processing Unit：CPU) storage is stored in by execution
The computer program in portion 12 is realizing each function.
In the white balance adjustment method of present embodiment, white balance adjustment device 91 executes white balance successively
Adjust the curve deriving step that point detecting step and voltage are with respect to white brightness.Hereinafter, with reference to Fig. 2 pair
Respectively sequentially illustrate.
In blank level adjustment point detecting step, every kind of illuminant color to display 93 for the information treatment part 11
Detect each blank level adjustment point P1～P5.Adjustment point P1～P5 includes the voltage of each illuminant color, for example,
Adjustment point P1 includes the voltage VG1 of the voltage VB1, red voltage VR1 and green of blueness.
Specifically, the voltage to every kind of luminous color adjustment display 93 for the chroma control function.Now, color
Degree adjustment function passes through the voltage of a kind of color in the illuminant color of fixing display 93 so as to its color
Voltage changes, thus showing white in display 93.For example, in the case of adjustment point P1,
Blueness is fixed on pre-set voltage VB1 by chroma control function, makes the voltage VR1 and green of redness
The voltage VG1 change of color.So, by fixing the voltage of a kind of color, remaining 2 kinds of colors are adjusted
Voltage although the brightness of blank level adjustment point has slight deviations, but can accelerate white balance adjust
Whole.
Here, the color of fixed voltage is preferably the electric current needing maximum in each illuminant color, and to other
The larger color of impact of illuminant color.
When measuring white with detector 92, white balance writing function is used for the display color of display 93
It is changed into brightness during white and the voltage of each illuminant color is recorded in storage part 12.For example, white balance record work(
Can be used for by the voltage (VB1, VR1, VG1) of each illuminant color in adjustment point P1 with detector 92
The brightness W1 measuring is recorded in storage part 12.For adjustment point P2～P5, chroma control function and Bai Ping
Weighing apparatus writing function is also carried out and adjusts point P1 identical action.Thus, by each adjustment point P1～P5
The voltage of each illuminant color and with detector 92 measure brightness be recorded in storage part 12.
Here, display 93 display complexion changed be white when be for example detected with detector 92 white
During color.Be whether white for example based on colourity whether consistent with pre-set colourity judging.In advance
The colourity setting is, for example, (Cx, Cy)=(0.3,0.32).Pre-set colourity can be
Within connecing subalbous certain value.
In voltage with respect in the curve deriving step of white brightness, voltage is with respect to the curve of white brightness
Export function is using the voltage of each illuminant color in each adjustment point P1～P5 being stored in storage part 12 and white
The brightness of color is deriving the curve with respect to white brightness for the voltage of each illuminant color.For example, using blue
Voltage VB1～VB5 derives the curve CB that blue voltage is with respect to white brightness, using voltage VR1～
VR5 derives the curve CR that red voltage is with respect to white brightness, is derived using voltage VG1～VG5
The voltage of green is with respect to the curve CG of white brightness.Have adjusted each of white balance thereby, it is possible to derive
Photochromic voltage is with respect to the curve of white brightness.
The brightness stride ratio being stored in each adjustment point P1～P5 of storage part 12 is illustrated by the broken lines in fig. 2
Blank level adjustment point in gamma tables is thick.If execution voltage is with respect to the curve deriving step of white brightness,
The curve with respect to white brightness for the voltage of each illuminant color as shown in Figure 2 then can be obtained.Can utilize
This voltage, with respect to the curve of white brightness, obtains the brightness with blank level adjustment point by interpolation calculation
The voltage of each suitable color.Thereby, it is possible to make the gamma tables of display 93.In addition, this result
Voltage not only meet brightness conditions, also meet white balance conditions.Will be by voltage with respect to white brightness
Curve export function derive gamma tables be stored in storage part 12 and display 93.
Should illustrate, preferred voltage is used for carrying out white balance with respect to the curve export function of white brightness
The Range-partition of the brightness of adjustment is multiple regions, each region is carried out with voltage with respect to white brightness
Curve deriving step.The region of segmentation is preferably based on voltage and carries out with respect to the characteristic of the curve of white brightness,
For example it is divided into high-brightness region, middle luminance area, low brightness area.Thereby, it is possible to derive accurately
Voltage is with respect to the curve of white brightness.
Additionally, the adjustment point P1～P5 in blank level adjustment point detecting step selects preferably in each region
The candidate of several suitable adjustment point P1～P5.For example, the brightness stride of adjustment point P1～P5 compares gamma
Blank level adjustment point in table is thick.In such manner, it is possible to using the tune fewer than the blank level adjustment point in gamma tables
Integral point derives gamma tables.
As described above, the invention of present embodiment can lead to cost to increase not increasing photographing unit etc.
In the case of special hardware, only pass through change algorithm and just can shorten attachment and adjustment time.
Industrial applicability
The present invention can be applied to display industry.
