Abstract

The present disclosure describes systems, methods, and devices for estimating spectral contributions in ambient light. The present disclosure also describes systems, methods, and devices for compensating for field of view errors resulting from the user, contextual structures (e.g., buildings, trees, fixtures, or geological formations), atmospheric effects (e.g., ozone coverage, smog, fog, haze, or clouds), device structures, and/or device orientation/tilt relative to a light source being measured (e.g., sun, indoor/outdoor light emitter, or an at least partially reflective surface). The present disclosure also describes systems, methods, and devices for estimating spectral contributions in light or color measurements and accounting for field of view errors to obtain a refined estimate.
