Problems solved by technology

However, in the existing technology, since the traditional oscilloscope cannot display the relative relationship between pixels, it is not possible to directly adjust the original image by adjusting the color model in the oscilloscope.
For example, the traditional color model does not display the color distribution corresponding to the original image, so the color adjustment cannot be adjusted to the color you need in one step.
[0006] In short, in the prior art, the control method of the oscilloscope is too abstract, and the user cannot intuitively adjust the original image according to the color model displayed by the oscilloscope

Abstract

The invention discloses a control method for a color space three-dimensional oscilloscope. The control method comprises obtaining integrally adjusted values input by a user or adjusted values of a specific pixel by introducing a three-dimensional oscillography model; obtaining a new three-dimensional oscillography model by adjusting the three-dimensional oscillography model according to the integrally adjusted values or the adjusted values of the specific pixel; adjusting an original image according to the new three-dimensional oscillography model, and obtaining a new image. Due to the fact that space coordinate points and colors on the three-dimensional oscillography model correspond o color values on the original image one to one, a user can achieve the aim of directly adjusting image according to adjustment of the colors on the three-dimensional oscillography model.

Description

technical field [0001] The invention relates to the field of image and video processing, in particular to a control method of a color space three-dimensional oscilloscope. 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" originates from the western "Color Space", also known as "color gamut". In color science, people have established a variety of color models to represent a certain One 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 blu...
