Claim One:
1. In a digital camera comprising an electronic image recorder for recording an overall image signal, said image recorder comprising a regular arrangement of pixels, each pixel having three light-sensitive image cells each covered by one of three different color filters, and each pixel thus generating three mutually independent image signals assigned to one of three colors, wherein said overall image signal comprises a color saturation, a method for modifying said color saturation, said method comprising the steps of: recording said mutually independent image signals in each of said pixels in a logarithmically compressed format, determining a logarithmically compressed brightness signal from said mutually independent image signals as an arithmetic mean of said mutually independent image signals, selecting at least one of said mutually independent image signals, and transforming said at least one independent image signal selected as a function of said logarithmically compressed brightness signal.
