Title:
IMAGE DATA GENERATION METHOD, DISPLAY BODY MANUFACTURING METHOD, PROGRAM, COMPUTER-READABLE RECORDING MEDIUM, AND DISPLAY BODY MANUFACTURING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/110703
Kind Code:
A1
Abstract:
Provided is a technology which enhances the reproducibility of an original image in an image after a binarization process. This image data generation method is provided with: acquiring first image data having a gradation value for each pixel with respect to each color; and generating, on the basis of the first image data, second image data having a binarized gradation value for each pixel with respect to each color, wherein the generating of the second image data includes: selecting a first pixel from the first image data; and binarizing the gradation value of the first pixel by means of first binarization process according to a comparison result showing that the gradation value of the first pixel is larger than a first threshold, binarizing the gradation value of the first pixel by means of a second binarization process according to a comparison result showing that the gradation value of the first pixel is smaller than a second threshold, and binarizing the gradation value of the first pixel by means of a third binarization process according to a comparison result showing that the gradation value of the first pixel is equal to or smaller than the first threshold and equal to or larger than the second threshold.
