Abstract

An image processing apparatus and a shading-information acquisition device have a sample table (21) adapted to rotate in a direction (.theta.1) about a rotational axis (Z1) and to rotate in a direction (.theta.2) about a rotational axis (Z2). An irradiation assembly (3) includes a support plate (31) adapted to rotate in the direction (.theta.1) about the rotational axis (Z1), an irradiation arm (33) adapted to rotate in a direction (.theta.3) about the rotational axis (Z3) and provided with a light radiation aperture (331) at the top end thereof. An optical fiber cable (36) guides light from a light source unit (34) to the light radiation aperture (331), and a camera (4) is disposed outside a dark box (6). The image processing apparatus and shading-information acquisition device perform a realistic shading processing for a virtual 3-dimensional model by a simple operation without complicated jobs for setting up various parameters.
