Differences in perceived naturalness and image quality have led to an information‐processing approach towards understanding image quality, thus challenging the traditional, signal‐processing approach. This paper presents a general image quality model integrating both approaches. The model assumes the existence of three constraints, i.e. fidelity, usefulness and naturalness. Image quality is modeled as the weighted sum of these constraints whereby the weighting depends on task, context, image content etc. Model predictions will be confronted with experimental data on optimizing color reproductions of natural scenes.
