Abstract: In a picture signal processing method, an analog picture signal (APS1, APS2) is processed (PSP) in dependence on a quality indication (QI1, Q12) relating to the analog picture signal (APS1, APS2) and received together with the analog picture signal (APS1, APS2). Preferably, the analog picture signal (APS1, APS2) has been obtained from a digital picture signal that has been encoded at a bit-rate and/or at a compression ratio and/or at a quantization level, wherein the quality indication (QI1, QI2) is the bit-rate and/or the compression ratio and/or the quantization level.

Abstract: A filter device (1) includes a main filter unit (10), such as a 2-D comb filter, implemented in hardware, with an input for receiving a video signal (?) and an output for providing a filtered video signal (?1), a controllable temporal noise reduction unit (20) receiving the filtered video signal (?1) from the main filter unit (10), to perform a noise reduction operation on the filtered video signal (?1), and a unit (14, 30, 40) for detecting a very low amount of motion in a video image of the filtered video signal (?1) and for controlling the controllable temporal noise reduction unit (20) on the basis of the detected very low amount of motion, so as to enable the filter device (1) to reduce cross-luminance and/or cross-color as well when only a very low amount of motion is present in the signal.

Abstract: In almost all contemporary TVs peaking techniques arc used today to enhance the picture. This means that the edges are sharpened in the luminance channel by using of peaking or peaking-like circuits such as, for instance, luminance transient improvement techniques. By such technique black parts near the edge are usually pushed towards more black color and white parts are pushed towards more white color. As a result the picture appears sharper and crisper. However, the picture also gives a “hard” impression in said parts, the reason for this being that the image signal has been corrected solely with regard to a luminance component and not with regard to a color component. The proposed method aims to increase the saturation level at those parts, in particular by processing the input image signal in a region of an edge location, wherein at least the image characteristics of a color component are corrected by amplifying the color component.

Abstract: A filter device (1) is described, comprising a main filter unit (10) such as a 2D comb filter, implemented in hardware, with an input for receiving a video signal (&PHgr;) and an output for providing a filtered video signal (&PHgr;1), a controllable temporal noise reduction unit (20) receiving said filtered video signal (&PHgr;1) from the main filter unit (10), to perform a noise reduction operation on said filtered video signal (&PHgr;1); and a unit (14, 30, 40) for detecting a very low amount of motion in a video image of said first video signal (&PHgr;1) and for controlling the controllable temporal noise reduction unit (20) on the basis of the detected very low amount of motion, so as to enable the filter device (1) to reduce cross-luminance and/or cross-color as well when only a very low amount of motion is present in the signal.
