Abstract
The present invention is directed to producing and reproducing an image using a tone reproduction curve which has been selected based on statistical evaluation of psychophysical data, such as psychophysically quantified subjective judgements. By providing a controlled acquisition and evaluation of psychophysical data to select a tone reproduction curve, visually improved imagery can be assured. Further, once a procedure for controlled acquisition and statistical evaluation of psychophysical data has been established for a given environment, lesser skilled technicians can be used to carry out selection of a tone reproduction curve.
