Abstract

The invention discloses a method for reproducing the projection display color of a colorful surface. The method comprises the steps of characterizing a projector camera system and a display surface color, determining a chroma color reproduction target value and calculating and realizing the color reproduction. The step of characterizing the projector camera system and a display surface color is used for representing the conversion relation of the input / output colors of the projector camera system and the color of the display surface; the step of determining the chroma color reproduction target value is used for setting a proper chroma reproduction target according to the input color value and a color reproduction range of the system on the colorful surface; and the step of calculating and realizing the color reproduction is used for correcting the color value of an original input image according to the conversion relation of the input / output colors of the system, the display surface color and the color reproduction target value so as to obtain the input color value. The system can automatically finish the entire chroma color reproduction process without needing any other measurement equipment or calibration color cards, the reproduction process is simple and hardware integration is easy to realize.

Description

technical field

[0001] The invention relates to a color reproduction method in the field of projection display, in particular to a chroma color reproduction method when projection display is performed on a color surface with random textures or patterns common in daily life. Background technique

[0002] Projection display is one of the digital image reproduction methods commonly used in people's daily work and life. Compared with other display methods, projection display is a display method that projects images on an auxiliary surface. It has the remarkable feature of separating the display surface from its own equipment, so that the size of the projection display screen is not restricted by the size of its own equipment. In order to make the use of the projector more flexible and convenient, the equipment size of the projector gradually presents a development trend of small size, portable and mobile with the in-depth development of modern technology. As a result, projectio...
