Abstract

An embodiment of the invention discloses a method and a system for color display of an ultra violet (UV) oscilloscope. The method comprises the steps of obtaining YUV values of a random pixel of an image; calculating delta YUV values of the random pixel displayed in the oscilloscope according to the YUV values of the random pixel; calculating coordinates of the random pixel in the oscilloscope according to the YUV values of the random pixel, and displaying the delta YUV values in the coordinates. In the embodiment, by enabling the YUV values of the random pixel of the image to be related with the coordinates of the pixel in the oscilloscope, and by calculating the coordinates of the pixel in the oscilloscope and displaying the delta YUV values, color oscillography is achieved.

Description

technical field [0001] The invention relates to the technical field of video and image processing, in particular to a method and system for color display of a UV oscilloscope. Background technique [0002] The RGB (red, green, blue) color space is a common color space in computers, which 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, and red, green, and blue each occupy 8 bits, and 256*256*256 colors can be obtained. [0003] The YUV color space is a color encoding method adopted by the European television system. Among them, "Y" represents the brightness (Luminance or Luma), that is, the grayscale value; while "U" and "V" represent the chroma (Chrominance or Chroma). Color TV uses YUV space just to solve the compatibility problem between color TV and black and white TV with brightness signal Y, so that black and white TV can also receive color TV signal. The YUV we often...
