Title:
スペクトルに基づき測色的に較正された多色カメラを用いたディスプレイの高速較正
Document Type and Number:
Japanese Patent JP6529936
Kind Code:
B2
Abstract:
Described are a system and method to calibrate displays using a spectral-based colorimetrically calibrated multicolor camera. Particularly, discussed are systems and methods for displaying a multicolor calibration pattern image on a display unit, capturing the multicolor calibration pattern image with a multicolor camera having a plurality of image sensors, with each image sensor configured to capture a predetermined color of light, comparing a set of reference absolute XYZ coordinates of a set of colors from the multicolor calibration pattern with a set of measured XYZ color coordinates captured using the colorimetrically calibrated camera, and calibrating the display unit based on the comparison between the reference coordinates and the measured coordinates.
