IMAGE PROCESSING FOR PROJECTION ON A PROJECTION SCREEN
First Claim
1. A method of processing an original image for projection on a projection screen by a projector, comprising performing pixel interpolation between pixels of a first image associated with the original image and pixels of a second image associated with a pixel grid of the projector, wherein at least one of the first image and the second image has a pixel resolution greater than the resolution of, respectively, the original image and the pixel grid.

Abstract
A method of processing an original image for projection on a projection screen by a projector, comprising performing pixel interpolation between pixels of a first image associated with the original image and pixels of a second image associated with a pixel grid of the projector, wherein at least one of the first image and the second image has a pixel resolution greater than the resolution of, respectively, the original image and the pixel grid.
Embodiments of the invention provide pixelization artifacts reduction in displaying high-definition videos with flexibility and low complexity.

36. A method of processing image data for projection on a projection screen by a plurality of projectors projecting respective image portions of an image, the method comprising the following steps:
-
receiving a first command associated with a modification of at least one portion of said image, and transmitting a second command for synchronous action to a first set of control units, based on the first command, said second command enabling said first set of control units to synchronously perform at least one action, by at least one projector of the plurality, in order to carry out said modification. - View Dependent Claims (37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 67)

- 61. A device for processing image data for projection on a projection screen by a plurality of projectors projecting respective image portions of an image, the device comprising a control unit configured for receiving a first command associated with a modification of at least one portion of said image, and for transmitting a second command for synchronous action to a first set of control units, based on the first command, said second command enabling said first set of control units to synchronously perform at least one action, by at least one projector of the plurality, in order to carry out said modification.
