  • Video picture format conversion method and corresponding device
    Patent number: 8264601
    Abstract: The present invention can be implemented in a video coder or decoder or directly in any type of display device. According to the invention, a distance representative of the edge orientation in the input picture is calculated, for at least one point situated inside a zone delimited by a first set of neighbouring pixels of the input picture, it is calculated independently from the grid of pixels of the output picture. For at least one pixel of the output picture situated in this zone, a second set of pixels is determined in the input picture from the distance and the position of said pixel of the output picture in this zone. The value of this output pixel is then determined from the value of the pixels of said second set of pixels. This method enables a reduction in the number of calculations for this format conversion.
