Abstract

The invention discloses a spliced screen color adjusting method and an adjusting device. The method comprises the following steps: acquiring brightness parameter values and colorimetric parameter values of one or more spliced sub-screens in the spliced screen; computing according to the brightness parameter values and the colorimetric parameter values so as to obtain a base brightness value and a base colorimetric value; and adjusting the colors of the spliced sub-screens in the spliced screen completely or partially by virtue of the base brightness value and the base colorimetric value. The technical scheme provided by the invention can simplify an operation process and improve an adjusting precision.

Description

technical field [0001] The invention relates to the field of video surveillance, in particular to a method and device for adjusting the color of a splicing screen. Background technique [0002] At present, with the rapid development of science and technology, all walks of life are committed to informatization construction, and the requirements for high-quality visualization of information have increased sharply, especially in the fields of safety monitoring, production and operation of large enterprises, medical care, and public security. In order to meet the needs of users, a large-screen splicing display came into being. However, with the expansion of application fields and industries, users have put forward more stringent requirements for large-screen splicing display screens. Among them, the most important thing is the consistency of color reproduction of each display unit. With the continuous expansion of the splicing screen area, the color saturation and consistency o...
