The LIP (logarithmic image processing) tools are mathematical models dedicated to the representation and processing of gray tones images. The underlying model is derived from the observation that digital camera response function can be described as a multiplication in logarithmic domain. In this paper we extend the logarithmic models to process color images and show how they can be used to implement low-light image enhancement in digital cameras.
