Abstract

Abstract A display control system for use in a display system (10) having digital interfaces is disclosed which, when software using color display is executed (CG33,14 & 15) in the display system (10) with digital interfaces, is capable of distinguishing the display contents thereof from one another. Specifically, the display control system (10) is adapted to generate a given number of pieces of brightness information different from one another in duty correspondingly to respective pieces of color code information or brightness code information, to set up the dots of a display screen (20) in two mutually adjacent areas, and to shift the above-mentioned brightness information to be given to one of the above-mentioned areas from the above-mentioned brightness information to be given to the other area in phase. Also, the above-mentioned code information may be converted into hatch patterns correspondingly to the dot and raster positions in display means (20).

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 101 words
A display control system for use in a display system having digital interfaces, said display control system characterized by: code information/brightness information conversion means (CG1) for generating a given number of pieces of brightness information different from one another in duty correspondingly to respective pieces of color code information or brightness code information; area setting means (52) for setting up dots on a display screen in two mutually adjacent areas; and phase shift means (CG1) for shifting said brightness information to be given to one of said two areas from said brightness information to be given to the other in phase.
Claim 2
Dependent Claim 101 words
A display control system for use in a display system having digital interfaces, said display control system characterized by: code information/brightness information conversion means (CG1) for generating a given number of pieces of brightness information different from one another in duty correspondingly to respective pieces of color code information or brightness code information; area setting means (52) for setting up dots on a display screen in two mutually adjacent areas; and phase shift means (CG1) for shifting said brightness information to be given to one of said two areas from said brightness information to be given to the other in phase.
Claim 3
Dependent Claim 25 words
A display control system as defined in Claim 1, wherein the amount of shift provided by said phase shift means (CG1) is about 180 degrees.
Claim 4
Dependent Claim 52 words
A display control system as defined in Claim 1 or 2, wherein said area setting means is adapted to set up areas such that the horizontally mutually adjacent areas of said display screen (20) differ from each other and the vertically mutually adjacent areas of said display screen differ from each other.
Claim 5
Dependent Claim 52 words
A display control system characterized by: code information output means (110) for outputting color code information or brightness code information; and hatch pattern conversion means (130) for converting said code information output from said code information output means to hatch patterns corresponding to the dot and raster positions in display means (20).
Claim 6
Dependent Claim 52 words
A display control system characterized by: code information output means (110) for outputting color code information or brightness code information; and hatch pattern conversion means (130) for converting said code information output from said code information output means to hatch patterns corresponding to the dot and raster positions in display means (20).
Claim 7
Dependent Claim 42 words
A display control system defined in Claim 4, wherein said hatch pattern conversion means (130) comprises a conversion circuit adapted to input said code information, dot count signals and line count signals, convert them to 1-dot signals, and output said 1-dot signals.
Claim 8
Dependent Claim 39 words
A display control system defined in Claim 4 or 5, wherein each of said hatch patterns in said hatch pattern conversion means (130) is set in m (m is an integer) dot(s) x n (n is an integer) dot(s).
Claim 9
Dependent Claim 30 words
A display control system defined in Claim 4, 5 or 6, wherein each of said hatch patterns in said hatch pattern conversion means (130) is set in a character box.
Claim 10
Dependent Claim 24 words
A display control system defined in any one of claims 4 to 7, wherein said display means (20) comprises a CRT or liquid crystal.
