Patent number: 11380239Abstract: The visibility of a display device under colored ambient light is improved. There is provided an image processing system for converting a color space represented by color components of image data. The image processing system includes a color space converter configured to correct the color components of the image data by converting the color space such that, with respect to particular color components in user-perceived color gamut widened by influence of chromatic adaptation caused by ambient light, the influence is maintained and such that, with respect to particular color components in user-perceived color gamut narrowed by the influence, the influence is canceled; and a display unit configured to display, as an output image, the image data using the corrected color components.Type: GrantFiled: November 7, 2019Date of Patent: July 5, 2022Assignee: EIZO CorporationInventors: Satomi Kidoguchi, Takashi Nakamae, Reo Aoki, Masataka Shoji
