CAMERA COLOR NOISE REDUCTION METHOD AND CIRCUIT

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.
