发明名称 METHOD AND SYSTEM FOR EVALUATING BRIGHTNESS FEELING OF SPACE
摘要 PROBLEM TO BE SOLVED: To provide an evaluation method and an evaluation system, which can precisely predict an evaluation value of brightness feeling of a space, even for the space in which a region having high brightness exists. SOLUTION: A computation means 11 extracts brightness distribution data in the range of effective visual field, from the brightness distribution data of a selected data file (S7), and calculates the occupation rate R in the brightness range according to the illumination intensity level from the extracted brightness distribution data (S8). The evaluation value B of the brightness feeling is calculated by substituting the occupation rate R in expression (1) (S9), and the calculated evaluation value B of the brightness feeling is displayed in a dialogue box D3 displayed on a screen of a display means 12 (liquid crystal display 3). Even when the region having the high brightness exists in the objective space, by evaluating the brightness feeling of the space according to the ratio of the region except for the region having such high brightness to the total, the evaluation value of the brightness feeling of the space can be precisely predicted, even for the space in which the region having the high brightness exists.
