Method and apparatus for increased color accuracy of display by compensating for observer's color vision properties

A method comprising:

• measuring current illumination conditions at an optical-see-through augmented-reality display;
• determining a color-compensating transform for a user of the display;
• determining object spectral radiance of at least a portion of a virtual object;
• based at least in part on the object spectral radiance, the color-compensating transform and the current illumination conditions, determining a display color of a least a portion of the virtual object;
• and
• displaying the virtual object on the display using the display color for the portion of the virtual object.

A system comprising:

• a processor;
• and
• a non-transitory computer-readable medium storing instructions operative to perform functions comprising:
• measuring illumination conditions of an environment;
• determining an estimate of spectral illumination based upon illumination condition measurements;
• determining information regarding color-matching characteristics of a user of the display;
• determining spectral reflectance characteristics of at least a portion of a virtual object;
• based at least in part on the spectral reflectance characteristics of the at least a portion of the virtual object, the estimate of spectral illumination and information regarding the color-matching characteristic of the user of the display, determining display color information for the at least a portion of the virtual object;
• and
• causing display of the at least a portion of the virtual object using the display using the determined display color information for the at least a portion of the virtual object.
