A fine particle measurement device includes a 4f optical system in an optical path that causes a beam spot of a laser output from a light source to form an image with respect to fine particles. The color data to be rendered is mapped into a second data set in an achievable color gamut space. Splitting the volume allows implementing a modified model for image acquisition where the physical movement of the x-ray source is taken into account because each of the patches is updated separately and sequentially. The displays are arrayed to generate a seamless composite image from the images provided by the displays. The case may be adapted for use in a compact disc jewel box having a square base and a square cover hinged to the base.
