Abstract
A system include an light emitter to generate a primary light, a filter to filter the primary light to substantially remove a spectrum energy in a wavelength band, a display device to present visual content using the filtered primary light, and a processing device to receive a visual content, calculate, in view of the filtered primary light, a metamer of the visual content, and provide, to the display device, the metamer of the visual content to display in view of the filtered light.
Claims20
A system, comprising:
- an light emitter to generate a primary light;
- a filter to filter the primary light to substantially remove a spectrum energy in a wavelength band;
- a display device to present visual content using the filtered primary light;
- and
- a processing device to:
- receive a visual content;
- calculate, in view of the filtered primary light, a metamer of the visual content;
- and
- provide, to the display device, the metamer of the visual content to display in view of the filtered light.
A method comprising:
- receiving, by a processing device, a visual content to be displayed on a display device;
- filtering a primary light, emitted from a light source associated with the display device, to substantially remove a spectrum energy in a wavelength band;
- calculating, in view of the filtered primary light, a metamer of the visual content;
- and
- providing, to the display device, the metamer of the visual content to display in view of the filtered light.
A non-transitory machine-readable storage medium storing instructions which, when executed, cause a processing device to perform operations comprising:
- receiving, by the processing device, a visual content to be displayed on a display device, wherein a primary light associated with the display device is filtered to substantially remove a spectrum energy in a wavelength band;
- calculating, in view of the filtered primary light, a metamer of the visual content;
- and
- providing, to the display device, the metamer of the visual content to display in view of the filtered light.
