Filed: 1996-06-18
Abstract: PROBLEM TO BE SOLVED: To recognize the change in color sensitivity with a high precision by computing the color sensitivity characteristics of a person in terms of numerical values for every age based on each part of his eye. SOLUTION: In an input device 1, the present age of the person and the target age, at which the change factor in his color sensitivity caused by the advance in his age is predicted, are inputted using a keyboard. A computing device 2 computes the change factor (an attenuation factor) of the two specified ages from the transmission factors of the RGB signals of the person under a test at every age. Then, a picture input device 3 reads the picture to be converted. A picture converting device 4 performs a density conversion against the RGB signal density of the picture inputted by the device 3 employing the change factor computed by the device 2. An output device 5 displays the results.  Then, the spectral transmission factor corresponding to the age in the optical transmission line is computed by multiplying the spectral transmission factor corresponding to the age for every part which is the part to constitute the eye equivalent to an optical path.
