20090079758 | Method and device for generating shadow maps - A method and a device for determining shadows in a computer-generated image are provided, wherein the determination whether a pixel x is in shadow is based on a shadow test function ƒ(d(x), z(P)), d(x) representing the depth of the pixel x with respect to the light source and z(p) being a shadow map z for the computer-generated image. According to the invention, the shadow test function ƒ satisfies | 03-26-2009 |

20100172411 | HIGH DYNAMIC RANGE CODECS - A method for encoding high dynamic ränge (HDR) images involves providing a lower dynamic ränge (LDR) image, generating a prediction function for estimating the values for pixels in the HDR image based on the values of corresponding pixels in the LDR image, and obtaining a residual frame based on differences between the pixel values of the HDR image and estimated pixel values. The LDR image, prediction function and residual frame can all be encoded in data from which either the LDR image of HDR image can be recreated. | 07-08-2010 |
