BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flesh color chart, and more particularly to a flesh color chart most suitable for evaluating photographic light-sensitive materials.

[0002]

2. Description of the Related Art In the evaluation of color photosensitive materials such as color photographic paper, color reproduction, especially skin color, is the most important evaluation target. Normally, in photos of people, color matching is actually performed based on the skin color, especially the skin color of the face, and the evaluation of the photosensitive material is determined by the quality of the skin color reproduction. It's not too much to say.

In particular, recently, the performance of photosensitive materials has been improved, the color reproduction has been vivid, and the saturation of flesh color has been increased.
In this case, a beautiful skin color is beautifully finished, but skin defects such as sunburn, acne, uneven makeup, and red skin also become noticeable. Also, now that corporate activities are globalized, there is a growing need to evaluate skin color differences due to race more severely than before.

[0004]

Therefore, in the development of photosensitive materials in the future, the development of evaluation methods and skin color evaluation techniques has become more indispensable than ever. However, at present, a chart capable of meeting these requirements has not been developed. Therefore, when evaluating the skin color reproducibility of the photosensitive material, real humans were collected and photographed, and the density of the obtained practical photograph was measured. For this reason, since a real person is required, there is a problem that the evaluation of skin color reproducibility cannot be easily performed. In addition, since a real person is photographed, there is a difference between individuals, and even if the same person is used, there is a difference due to a change in physical condition, an age change, and the like, which causes a problem that quantitative evaluation becomes difficult.
