摘要:
L'invention porte sur un dispositif de traitement d'une image numérique initiale comportant au moins une zone de contour, ledit dispositif comprenant des moyens d'agrandissement (MAGR) aptes à agrandir l'image initiale en une image numérique agrandie. Les moyens d'agrandissement comportent des moyens de détection aptes à détecter les zones de contours de l'image numérique initiale, des moyens de détermination (MD) aptes à déterminer la taille, en nombre de pixels, de chaque zone de contour, et des moyens d'agrandissement aptes à agrandir chaque zone de contour à l'aide d'un outil logiciel, choisi en fonction de la taille de chaque zone de contour, parmi un ensemble d'outils logiciels d'agrandissement.
摘要:
A method includes identifying a pair of image data blocks separated by a boundary. The image data blocks include image information defining multiple pixels in at least one image. The method also includes identifying at least one filter length based on edge contents of at least some of the pixels in the at least one image. In addition, the method includes filtering at least some of the pixels in the pair of image data blocks along the boundary using the at least one identified filter length.

A method of colour saturation compensation in a video signal is disclosed. The method includes the steps of: processing a luminance signal component of the video signal; determining whether the processing of the luminance signal results in a change in chrominance saturation; if the step of determining reveals that the chrominance saturation has changed, applying a chrominance compensation signal to the chrominance signals to counteract the effects of chrominance saturation, wherein said step of applying a compensation signal include the steps of: generating a compensation signal which is dependent on hue and luminance ratio (output luminance signal / input luminance signal). Apparatus for performing the method is also disclosed.
