摘要： Image color noise reduction circuit (20) and image processing method for processing a digital image having primary color signals (R; G; B). A determination circuit (27) determines a maximum signal value (Signaltype) from the primary color signals. A calculation circuit (29) connected to the determination circuit (27) reduces a color saturation of the digital image by modifying the primary color signals or signals related thereto depending on the maximum signal value. The color saturation is reduced at least for low values of the primary color signals or signals related thereto.

摘要： The present invention relates to interpolating a missing color value of a given pixel in an array of pixels. The missing color value is determined from color values of neighboring pixels using a median-based technique in which the median is taken of the four pixels values of the horizontally and vertically neighboring pixels (G1–G4) having a same color as the missing color value, and color information from at least one other color (R/B) at the given pixel.

摘要： A television field deflection circuit with a rapidly controllable large linearity. The deflection current is integrated in a first integrator which is followed by a second integrator having an adjustable time constant. The signals integrated once and twice are applied to a difference amplifier, while the signal integrated once is inverted and is adjustable through a feedback circuit. Subsequently a signal combination is formed of a non-integrated signal, a signal integrated once in phase, an adjustable signal integrated once in opposite phase and an adjustable signal integrated twice. The signal combination is fed back to a difference amplifier through which the deflection coil is fed and to which furthermore a sawtooth-shaped signal with a parabolic component is applied.

摘要： Conventional color saturation control CSC in a non-linear signal domain may result in exaggerated and unnatural looking colors. The invention proposes an image signal processing method (30A, 30B) of a color saturation control (17) which applies a gain value (27) to the saturation controlled image signal (Y′, satx(R′-Y′), satx(B′-Y′)) in a color restoration (10) which results in an output signal (Yo′, (R′-Y′)o, (B′-Y′)o). The gain value (27) is determined such that a maximum value of a color in the input signal is maintained in the output signal (Yo′, (R′-Y′)o, (B′-Y′)o). Thereby in particular the symmetry of the 3Dcolor space is maintained, preferably by controlling at least the maximum values of three primary colors (R, G, B) when increasing the saturation. In a preferred configuration the saturation controlled color difference image signals (satx(R′-Y′), satx(B′-Y′)) are transformed to the RGB-domain to obtain an RGB-measure of the increased saturation. Also the color difference input image signals (R′-Y′, B′-Y′) are transformed to analyze the original level of saturation. On this basis a first (RGBmaxsat′) and a second (RGBmax′) color maximum value are determined and used to determine the gain value (27).
