Description

The image adjustment system of projection arrangement and image regulating method

Technical field

The present invention relates to a kind of image adjustment system and image regulating method, be meant a kind of image adjustment system and image regulating method that is applied on the projection arrangement especially.

Background technology

Consult Fig. 1, digital light handles that (Digital light processing, DLP) optical projection system 1 comprises: light source cell 11, adjustment unit 12, an image-generating unit 13, and a processing unit 14.Generally speaking; This light source cell 11 (for example: a white light bulb) cooperate this adjustment unit 12 to filter out the light of different colours, and then (for example: the ray cast that micromirror (DMD)) will meet image color is accomplished imaging to screen 10 through this image-generating unit 13.

Unite and consult Fig. 1,2; Because it is to come video picture according to the principle of color (Sequential color) in proper order that this digital light is handled optical projection system; So generally speaking this adjustment unit 12 comprises a colour wheel (Color wheel) 121 and aperture elements (Aperture) 122; The color lump district that the red, green, blue look is arranged respectively on this colour wheel 121, the control signal that cooperates processing unit 14 to be sent by the mode of rotating is to filter the light that this light source cell 11 is sent; Make it present the needed color of image; This aperture elements 122 then is a wheel member with glass material zone 120, can change light-inletting quantity by suitable and this colour wheel 121 are overlapping, and then can adjust the dynamic contrast (Dynamic contrast) of image.

Can learn according to above-mentioned; Handle in the optical projection system at digital light now; Can strengthen the dynamic contrast characteristic of light by the position of this aperture elements 122 of adjustment; But,, can only utilize color space transformation matrix (Colorspace converter matrix of digital mode adjustment by this processing unit 14 if want to change the saturation degree (Color Saturation) and the colour temperature (Color temperature) of light; CSC matrix) to adjust, this color space transformation matrix is as follows:

[\begin{matrix} R \\ G B \\ 1 \end{matrix}] = [\begin{matrix} RGain & 0 & 0 & 0 \\ 0 & GGain & 0 & 0 \\ 0 & 0 & BGain & 0 \\ 0 & 0 & 0 & 1 \end{matrix}] [\begin{matrix} C_{11} & C_{12} & C_{13} & 0 \\ C_{21} & C_{22} & C_{23} & 0 \\ C_{31} & C_{32} & C_{33} & 0 \\ 0 & 0 & 0 & 1 \end{matrix}] [\begin{matrix} Contrast & 0 & 0 & Bright \\ 0 & S \times \cos θ & - S \times \sin θ & 0 \\ 0 & S \times \sin θ & S \times \cos θ & 0 \\ 0 & 0 & 0 & 1 \end{matrix}] [\begin{matrix} Y \\ Cb Cr \\ 1 \end{matrix}]

Wherein, RGain, GGain, BGain are respectively a color temperature parameters, C _IjBe a form and aspect parameter, S is a color saturation parameter.

Yet adjust the practice of digital signal like this; But be easy to generate edge effect (Side effect); For example: adjust those color temperature parameters RGain, GGain, BGain when changing the colour temperature of image, might cause the degradation in contrast of image or make the image overexposure, if adjust the saturation degree of image with the color saturation parameter S; Then might let the color supersaturation of image, make the color range of image become and be difficult to differentiate.Therefore, handle optical projection system for digital light, the characteristics such as colour temperature, saturation degree, brightness that how to overcome the adjustment image be easy to generate the problem of edge effect real belong to important.
