摘要： A surface light source device includes a surface light-emitting light-guiding unit; an LED light source disposed at an outside position on a side of a direction of the light incident surface; a plurality of laser light sources disposed at an outside position on a side of a direction of a rear surface of the surface light-emitting light-guiding unit; and a laser-light-ray guiding unit arranged on a side of a rear surface of the surface light-emitting light-guiding unit. The laser-light-ray guiding unit guides the laser light rays emitted from the laser light sources so that the laser light rays enter through a light incident end surface, travel in a direction opposite to a direction in which the LED light source emits the LED light ray, and thereafter are reflected by a light bending part to enter through the light incident surface of the surface light-emitting light-guiding unit.

摘要： A light intensity distribution conversion element has a light incident surface, a light emission surface, and total reflection surfaces. Light having directivity enters the light incident surface. The light emission surface has a curved surface portion of a concave shape with respect to an emitting direction of the light, for broadening an angular intensity distribution of the light. The total reflection surfaces are near or are adjacent to the curved surface portion, are slanted against the emitting direction of the light, and totally reflect the light. The light reflected by the total reflection surfaces is emitted from the curved surface portion.

摘要： A color conversion apparatus receives red-green-blue color data, calculates characteristic information and first hue region data from the color data, adjusts the first hue region data according to the characteristic information to obtain second to N-th hue region data, N being an integer equal to or greater than three, generates matrix coefficients for the second to N-th hue region data, and performs a matrix operation on the second to N-th hue region data to obtain color data with four or more color components. Color data with three primary components are thereby converted to color data with four or more primary components by simple calculations, without using a large amount of memory space.

摘要： An image data generator generates first image data consisting of a plurality of color data and being an image information for each pixel. An image processor including a color converter applies image processing such as color conversion on the first image data. An image display unit displays an image using image data consisting of second color data. An image data output unit outputs the first image data to the outside. The image display unit performs image display using the image data having received image-processing such as color conversion, while the image data output unit and outputs to the outside the image data before receiving the image processing. It is possible to obtain an image processing device capable of realizing an “exact color reproduction” or a “preferred color reproduction” on an image display image display unit, and outputting, to the outside, image data in the form of a standard image data, without reflecting the characteristics of the image display unit.
