Abstract: An image adapter transforms an input image into an output image by successively processing tiles and by changing numbers of columns and of rows of image points. The image adapter includes queue memories connected in series so as to receive values associated with the points of a tile of the input image. A module for calculating a weighted average possesses inputs connected respectively to an output of one of the memories. The module produces values sampled in a direction parallel to the columns and corresponding to the values associated with points of the input image. A sampling rate converter, connected to the output of the module, produces values associated with the points of the output image according to a sampling rate determined for a direction parallel to the rows.

Abstract: A multi-standard deblocking filter for deblocking video images including a deblocking unit configured to deblock edges of a current macroblock of an image based on samples taken from a first sample window comprising said current macroblock and a second sample window adjacent to said first sample window; three memory banks coupled to said deblocking unit, a first memory bank arranged to store samples of said first sample window, a second memory bank arranged to store samples of said second sample window, and a third memory bank arranged to store samples of a third sample window adjacent to the second sample window comprising a macroblock deblocked in a previous deblocking operation; and control circuitry to control, during a same macroblock deblocking operation, loading and deblocking of said current macroblock and outputting of samples of said third sample window from the third memory bank.

Abstract: A method and a device for processing an image to be displayed with a reduced number n of color components are disclosed. The method comprises, for at least one of the color components, a reduction operation that is carried out by means of a dynamic round off dependent on the position (x, y) of the pixel to display. Thus, in a very simple way, image processing preventing the occurrence of artifacts, flickering or other flaws that the reduction of the number of colors would inevitably produce, can be realized.
