Abstract

The invention discloses a method for mapping a color model in a color oscilloscope to a three-dimensional space. By introducing a Cartesian coordinate system in the color oscilloscope, original image data is converted into target form image data; according to categories of each component in the target form image data, each coordinate axis in the Cartesian coordinate system is identified, and value area of each coordinate axis is determined according to a form of image data; a component of each pixel point in the target form image data is converted into three-dimensional data value in the Cartesian coordinate system according to a conversion algorithm; according to the three-dimensional data value, corresponding color and position of each pixel point in the Cartesian coordinate system are calculated. The color is marked at the position, a three-dimensional oscillometric model is obtained, and visual reflection of space distribution conditions of the pixel points is achieved.

Description

technical field [0001] The invention relates to the field of image and video processing, in particular to a method for mapping a color model in a color oscilloscope to a three-dimensional space. Background technique [0002] With the emergence of nonlinear editing system, the post-production of TV programs, especially the processing technology of video and image has been greatly developed. In image processing technology, color space is a commonly used concept. The term "color space" comes from the western "ColorSpace", also known as "color gamut". Color, the color range that can be defined by this coordinate system is the color space. [0003] The RGB (red, green and blue) color space is a common color space in computers. It generates other colors by adding the three primary colors of red, green and blue. Among them, RGB24 uses 24 bits to represent the color of a pixel point, red, green, and blue each occupy 8 bits (there are 256 colors ranging from 00000000 to 11111111 f...
