Abstract
In accordance with one implementation, a method for multiple source light output smoothing includes measuring a light distribution generated by multiple light sources arranged within an electronic device and determining at least one brightness adjustment based on the measured light distribution that is sufficient to locally reduce light output within a discrete region of a surface of the electronic device to satisfy predefined luminosity criteria. The method further includes applying an optical filter between the multiple light sources and the surface, the optical filter configured to reduce light output within the discrete region according to the determined at least one brightness adjustment.

A method comprising:
- measuring a light distribution generated by multiple light sources arranged within an electronic device;
- determining at least one brightness adjustment based on the measured light distribution, the at least one brightness adjustment sufficient to locally reduce light output within a discrete region of a surface of the electronic device to satisfy predefined luminosity criteria;
- and
- applying an optical filter between the multiple light sources and the surface, the optical filter configured to reduce light output within the discrete region according to the at least one brightness adjustment.
An electronic device including:
- multiple light sources collectively providing a light distribution at a surface of the electronic device;
- and
- an optical filter positioned between the multiple light sources and the surface, the optical filter including a plurality of individually-tuned cells each configured to reduce brightness within a corresponding area of the surface of the electronic device to satisfy predefined luminosity criteria.
A method comprising:
- determining a plurality of brightness adjustments corresponding to a plurality of discrete regions of a device surface illuminated by multiple light sources, the plurality of brightness adjustments sufficient to alter a distribution of light at the device surface to satisfy predefined luminosity criteria;
- applying an optical filter between the device surface and the multiple light sources, the optical filter including a plurality of individually-tuned cells configured to reduce light output at the device surface according to the determined plurality of brightness adjustments.
