METHOD FOR CORRECTING COLOUR DEFICIENCY, THE FILTER USED IN THE METHOD AND METHOD FOR PROVIDING THE FILTER |
摘要 |
There is disclosed a method for providing a filter (3) for correcting colour deficiency. The method includes the following steps: a, the spectral response curves of the colour deficient person are determined; b, the spectrum to be observed is determined; c, the colour perception response signals generated by the given spectrum and associated to the spectral response curves of a person with normal colour vision are determined; d, the spectral transmission function of the filter is defined with parameters; e, the spectral response signals generated by the given spectrum and using the filter, associated to the colour deficient spectral response curves are determined; f, the filtered response signals are compared to the response signals of the person with normal colour vision; g, the parameters providing the best approximation are determined. There is also provided a method for correcting colour deficiency with a filter fitted to the specific colour deficiency of that person, so that the visual colour perception resulting from the observation of a given spectrum resembles the colour perception of people with normal colour vision.
