The present disclosure attempts to evaluate how the texture of an object is perceived based on visual features of the topological skeleton of the object. A camera Sobtains a color image by taking an image of an object, which serves as an evaluation target. Within the image obtained, a visual feature area, which is likely to strike a person's eye when the person claps his/her eyes on the object, and an intensity of a visual stimulus of each pixel of the visual feature area are extracted. Visual skeleton features of each pixel of the image are determined within a contour region which is composed of the visual feature areas extracted. The visual skeleton features determined are shown on a display.

Texture evaluation system

An edge of, for example, a windshield which serves as range of vision is defined by front pillars, a roof, and a dashboard. A modification area is provided at a peripheral portion of the windshield. In the modification area, visual saliency (visual conspicuousness) can be partially increased by means of, e.g., liquid crystals.

Device controlling range of vision

There are provided view adjustment areas respectively at an upper edge part, a lower edge part, and right-and-left side edge parts of a windshield glass, wherein the view adjustment areas are configured to be respectively switchable between in a transparent state in which forward visibility is ensured and in a translucent or non-transparent state in which the forward visibility is limited (for example, adhesion of a liquid-crystal film). Thereby, the size or the shape of the window-frame structure of the windshield glass which is physically unchangeable can be visually changed.
