Abstract
Abstract A method for displaying an image to a display device is provided. This method includes sequentially the steps of receiving the image in a first data format, performing a white balance correction in combination with a gamma correction for the image in the first data format, performing a color correction in combination with a color space conversion to a second data format for the image, and displaying the image in the second data format to the display device. This method reduces the number of multiplications required in the conversion of an image from the first data format to the second data format. This results in significant savings in CPU time, and more images may be displayed within a certain amount of time.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
77 words
A method for displaying an image to a display device, the method comprising the steps of: (a) receiving the image in red-green-blue data format; (b) performing a white balance correction in combination with a gamma correction of the red-green-blue data for the image; (c) performing a color correction in combination with a color space conversion to YCC format of the red-green-blue data for the image; and (d) displaying the image in YCC format to the display device.
Claim 2
Independent Claim
77 words
A method for displaying an image to a display device, the method comprising the steps of: (a) receiving the image in red-green-blue data format; (b) performing a white balance correction in combination with a gamma correction of the red-green-blue data for the image; (c) performing a color correction in combination with a color space conversion to YCC format of the red-green-blue data for the image; and (d) displaying the image in YCC format to the display device.
Claim 3
Dependent Claim
33 words
The method in claim 1 , wherein the performing step (b) comprises: (b1) performing the white balance correction with a plurality of multiplications; and (b2) performing the gamma correction with a look-up table.
Claim 4
Dependent Claim
29 words
The method in claim 1 , wherein the performing step (b) comprises pre-computing white balance correction values and combining them with gamma correction values into a single look-up table.
Claim 5
Dependent Claim
23 words
The method in claim 1 , wherein the performing step (c) comprises a multiplication of one 3-by 3 matrix with another 3-by-3 matrix.
Claim 6
Independent Claim
76 words
A system for displaying an image to a display device, comprising: means for receiving the image in red-green-blue data format; means for performing a white balance correction in combination with a gamma correction of the red-green-blue data for the image; means for performing a color correction in combination with a color space conversion to YCC format of the red-green-blue data for the image; and means for displaying the image in YCC format to the display device.
Claim 7
Independent Claim
76 words
A system for displaying an image to a display device, comprising: means for receiving the image in red-green-blue data format; means for performing a white balance correction in combination with a gamma correction of the red-green-blue data for the image; means for performing a color correction in combination with a color space conversion to YCC format of the red-green-blue data for the image; and means for displaying the image in YCC format to the display device.
Claim 8
Dependent Claim
37 words
The system in claim 5 , wherein the white balance correction and gamma correction means comprises: means for performing the white balance correction with three multiplications; and means for performing the gamma correction with a look-up table.
Claim 9
Dependent Claim
35 words
The system in claim 5 , wherein the white balance correction and gamma correction means comprises means for pre-computing white balance correction values and combining them with gamma correction values into a single look-up table.
Claim 10
Dependent Claim
32 words
The system in claim 5 , wherein the color correction means in combination with the color space conversion means comprises a multiplication of one 3-by- 3 matrix with another 3-by- 3 matrix.
Claim 11
Dependent Claim
79 words
A computer readable medium with computer instructions for displaying an image to a display device, comprising: (a) receiving the image in a red-green-blue data format; (b) performing a white balance correction in combination with a gamma correction of the image in the red-green-blue data format; (c) performing a color correction in combination with a color space conversion to a YCC data format for the image; and (d) displaying the image in the YCC data format to the display device.
Claim 12
Dependent Claim
