Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
60 words
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.
Claim 2
Dependent Claim
60 words
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.
Claim 3
Dependent Claim
20 words
The method according to claim 1 wherein said one of the color component signals is the blue color component signal.
Claim 4
Dependent Claim
16 words
The method according to claim 2 wherein said blue color component signal is displayed in monochrome.
Claim 5
Independent Claim
69 words
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.
Claim 6
Independent Claim
69 words
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.
Claim 7
Independent Claim
59 words
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.
Claim 8
Independent Claim
59 words
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.
Claim 9
Dependent Claim
70 words
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.
Claim 10
Dependent Claim
70 words
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.
Claim 11
Dependent Claim
62 words
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.
Claim 12
Dependent Claim
62 words
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.
