Abstract

Abstract A video processing system is described for providing an image having more than one region on a display (DISPLAY). The system has a control means which can determine, for each region, the type (e.g., graphics, text, computer programs, broadcast TV video, etc.) of the image material being displayed in the region. The system also has a video driver coupled to the display for providing image signals having contrast and brightness characteristics. The control means generates a control signal for causing said video driver means to adjust said contrast and brightness characteristics of said image signals according to the type of material being displayed in said region.

Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 111 words
A video processing system for providing an image having more than one region, comprising: means for obtaining for each region of the image, data indicating a type of information to be displayed in each region before processing the information in each region; means for deriving a display level for each region of the image according to the data obtained indicating the type of information being displayed in each region; and means for adjusting the display level for each region as the image is displayed, wherein the display level is derived by obtaining a normal drive level for each pixel and an attenuation number for each region of the image being displayed.
Claim 2
Dependent Claim 111 words
A video processing system for providing an image having more than one region, comprising: means for obtaining for each region of the image, data indicating a type of information to be displayed in each region before processing the information in each region; means for deriving a display level for each region of the image according to the data obtained indicating the type of information being displayed in each region; and means for adjusting the display level for each region as the image is displayed, wherein the display level is derived by obtaining a normal drive level for each pixel and an attenuation number for each region of the image being displayed.
Claim 3
Dependent Claim 17 words
The system of claim 1 wherein the data indicate that the information corresponds to a television program.
Claim 4
Dependent Claim 19 words
The system of claim 1 wherein the data indicate that the information corresponds to computer generated text and/or graphics.
Claim 5
Dependent Claim 20 words
The system of claim 1 , 2 , or 3 , wherein the display level corresponds to a contrast level.
Claim 6
Dependent Claim 20 words
The system of claim 1 , 2 , or 3 , wherein the display level corresponds to a brightness level.
Claim 7
Dependent Claim 32 words
The system of claim 1 , wherein the display level for each pixel of the image is derived by multiplication of the normal drive level and the attenuation number for the pixel.
Claim 8
Dependent Claim 19 words
The system of claim 1 wherein the data obtained is provided by a program associated with a particular region.
Claim 9
Dependent Claim 14 words
The system of claim 1 wherein the data obtained is specified by a user.
Claim 10
Independent Claim 104 words
A method for providing a displayed image having more than one display region comprising the steps of: obtaining for each region of the displayed image, data indicating a type of information to be displayed in each region before processing the information in each region; deriving a display level for each region of the image according to the data previously obtained indicating the type of information being displayed in each region by obtaining a normal drive level for each pixel and an attenuation number for each region of the image being displayed; and adjusting the display level for each region as the image is displayed.
Claim 11
Independent Claim 104 words
A method for providing a displayed image having more than one display region comprising the steps of: obtaining for each region of the displayed image, data indicating a type of information to be displayed in each region before processing the information in each region; deriving a display level for each region of the image according to the data previously obtained indicating the type of information being displayed in each region by obtaining a normal drive level for each pixel and an attenuation number for each region of the image being displayed; and adjusting the display level for each region as the image is displayed.
Claim 12
Dependent Claim 17 words
The method of claim 9 wherein the data indicate that the information corresponds to a television program.
Claim 13
Dependent Claim 19 words
The method of claim 9 wherein the data indicate that the information corresponds to computer generated text and/or graphics.
Claim 14
Dependent Claim 20 words
The method of claim 9 , 10 , or 11 , wherein the display level corresponds to a contrast level.
Claim 15
Dependent Claim 20 words
The method of claim 9 , 10 , or 11 , wherein the display level corresponds to a brightness level.
Claim 16
Dependent Claim 33 words
The method of claim 9 , wherein the display level for each pixel of the displayed image is derived by multiplication of the normal drive level and the attenuation number for the pixel.
Claim 17
Dependent Claim 19 words
The method of claim 10 wherein the data obtained is provided by a program associated with a particular region.
Claim 18
Dependent Claim 14 words
The method of claim 10 wherein the data obtained is specified by a user.
