The structure of gloss perception of human vision is not clear in the present time. A model of gloss perception using the operation resembling retina is proposed in this paper. The various reflected-light-intensity-distributions projected on the photo-sensor corresponding to the human visual cell are simulated with a computer. The distribution is transformed into an internal signal corresponding with the output of visual cell by modeling the visual adaptation. The output-distribution is obtained by the convolution-integral of the internal signal with DOG function that is similar to the sensitivity of the receptive field of ganglion cell. As the results, it is found that the maximum value Hmax
of the output-distribution has the characteristic similar to the psychological glossiness as follows.
(1) The maximum value Hmax
increases according as the psychological glossiness increases, when the specimens with the same curvature radius are used.
(2) When the curvature radius changes, Hmax
also changes and has the maximum value at a curvature radius. According as the psychological glossiness of a specimen decreases, the curvature radius at which Hmax
becomes a maximum decreases. This phenomenon is similar to that of psychological glossiness. Furthermore, it is likely that the half width of reflected-light-intensity-distribution roughly equals to the size of on-response field in receptive field.
