Embodiment Construction
[0036] The present invention provides a method and system for automatically simulating colors projected by a projector. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0037] See figure 1 , the present invention provides a kind of color automatic simulation method of projector projection, and it comprises the following steps:
[0038] S100. Obtain a brightness curve and a contrast curve by measuring the gray scale performance and color performance of the image;
[0039] S200. Obtain corrected brightness and contrast according to the brightness curve and the contrast curve.
[0040] Also, see figure 2 , the embodiment of the present invention acquires the parameters of the projector by collecting im...

The invention discloses a method and a system for automatically simulating projection colors of a projector. The method comprises the following steps: A. measuring the gray level performance and the color performance of an image to obtain a brightness curve and a contrast curve; and B. obtaining corrected brightness and contrast according to the brightness curve and the contrast curve. According to the method disclosed by the invention, image collection is carried out on a screen using the projector for projecting to obtain the parameters of the projector, and a final projection result of the projector is simulated on a computer, so that a user can master the onsite projection conditions of the projector at any time and adjust the parameters of the projector according to onsite environments at any time to obtain an optimal projection result, and thus the practicability is high and the market application prospect is brilliant.
Description
technical field [0001] The invention relates to the field of color correction, in particular to an automatic color simulation method and system for projector projection. Background technique [0002] High-resolution, high-brightness display systems have been used more and more in the fields of scientific computing visualization, industrial design, virtual manufacturing, entertainment, and military simulation. However, due to the influence of many factors, there may be problems with color cast or brightness of the screen. At this time, a system is needed to process the color and brightness of the picture. [0003] In the process of projecting with a projector, the picture quality will be poor due to the following factors: [0004] Reasons for the quality of the video source itself: the colors used exceed the capabilities of the projector, such as oversaturated colors, etc.; brightness problems such as insufficient or excessive color brightness; insufficient or excessive col...
