The correctness of color vision is the essential problem in Lighting Technology, Human Computer Interaction and Computer Graphics. To answer the question about correctness of perception process the workings of the whole human vision system should be analyzed. The color information can be falsified in the perception process. In many cases it is useful for us but often does not allow obtaining information about true color in proper way. But what is really true: the measured color or our “real subjective” perception?

PL

Percepcja barw jest jednym z podstawowych problemów techniki świetlnej, grafiki komputerowej i komunikacji człowiek-komputer. Aby odpowiedzieć na pytanie o poprawność interpretacji wrażeń barwnych, cały proces widzenia musi zostać przeanalizowany. Informacja o barwie może być fałszowana w procesie percepcji, często jest to dla nas korzystne. Powstaje jednak pytanie: na ile jest to subiektywne, czy oko jest dobrym instrumentem oceny barw?
