Abstract

This invention relates to the display, in monochrome, of color television component decoded signals red, green and especially blue, and particularly to a method of displaying transmission and recording system produced defects of color television signals which gives improved visual perception of the defects in the chrominance signal thereof in National Television System Committee and Phase Alternation Line color television systems.

Claims

1. In a method for displaying system produced defects of color television composite video color decoded component signals wherein the decoded signals are applied to separate electron guns of a color display device, the improvement comprising:

applying one of the decoded signals to each of the separate electron guns to thereby improve the visual perception of the defects on the display.

2. The method according to claim 1 wherein said one of the color component signals is the blue color component signal.

3. The method according to claim 2 wherein said blue color component signal is displayed in monochrome.

4. A method for displaying system produced defects of color television composite video signals, comprising:

providing a monochrome display device for visually displaying the defects, said display device including a single electron gun;

processing the composite video signals to provide primary color decoded component signals; and

applying one of said color decoded component signals to said electron gun to thereby provide visual perception of the defects on said display device.

5. A system for displaying system produced defects of color television composite video color decoded component signals wherein the decoded signals are applied to separate electron guns of a color display device, comprising:

means for applying one of the decoded signals to each of the separate electron guns to thereby improve the visual perception of the defects on the display.

6. In a method for displaying system produced defects of color television decoded component signals wherein decoded component signals are applied to electron control means for controlling color details of a display device, the improvement comprising:

applying one of the decoded components to the electron control means so that the electron control means causes the highest visual perceived brightness to thereby improve the visual perception of the defects on the display.

7. In a method for displaying system produced defects of color television composite video color decoded component signals wherein decoded signals are applied to separate electron guns of a color display device, the improvement comprising:

applying one of the decoded component signals to at least one of the other electron guns to thereby improve the visual perception of the defects on the display.
