Abstract: A method when expressing gradation for a color image including binarizing tone values of first image data to produce second image data including pixels each having colors with respective binarized tone values, classifying pixels of the first image data into a plurality of first pixel groups and specifying a pixel where a color centroid is positioned for each color in each first pixel group, classifying pixels of the second image data into second pixel groups PXG2 corresponding to the first pixel groups and calculating the number of light pixels for each color in each second pixel group, producing third image data from the second image data, information related to the color centroid, and information related to the number of light pixels, and producing fourth image data by changing the position of a light pixel with the position of a dark pixel in the third image data.

Abstract: A display of the present invention includes a multilayer film and at least one reflective surface. The multilayer film includes a laminate of at least two dielectric layers having refractive indices different from each other, and the laminate has a first major surface and a second major surface. The laminate has at least one recess formed in the first major surface. At least one reflective surface which faces the second major surface of the laminate, and is configured to direct light in a visible range, which has entered the multilayer film and then emerged at an angle of emergence from the second major surface, to be incident on the second major surface at an angle of incidence which is different from the angle of emergence of the light.

Abstract: A method of generating image data by acquiring first image data having a tone value of each pixel for each color and generating second image data. Generating the second image data by selecting a first pixel of the first image data; binarizing the tone value of the first pixel in response to a comparison result showing that the tone value of the first pixel is greater than the first threshold, binarizing the tone value of the first pixel in response to a comparison result showing that the tone value of the first pixel is smaller than the second threshold, and binarizing the tone value of the first pixel in response to a comparison result showing that the tone value of the first pixel is equal to or less than the first threshold and is equal to or greater than the second threshold.
