Abstract (en)

[origin: WO9900975A1] In the case of images comprising an area made up of pixels, the contrast observation in darker parts of the image can be improved by varying, as a function of the initial lightness of a pixel, the brightness and/or colour and/or spatial filtering of said pixel. The variation is smaller as the initial brightness increases.
