A color automatic simulation method and system for projector projection

Abstract

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 a method and system for automatic color simulation of projector projection. Background technique [0002] High-resolution and brightness display systems have been increasingly used in the fields of scientific computing visualization, industrial design, virtual manufacturing, entertainment, and military simulation. However, due to many factors, it may cause color cast or brightness problems on the screen. At this time, a system is needed to process the color and brightness of the screen. [0003] In the process of using a projector to project, the picture quality will be poor due to the following factors: [0004] The reasons for the quality of the video source itself: the colors used are beyond the capabilities of the projector, such as over-saturated colors; brightness problems such as insufficient or over-bright color; insufficient or excessive color contrast; color cast, etc. [0005] ...
