Claim One:
1. A method of estimating the spectral contributions in ambient light, comprising: receiving a light measurement from a first sensor of a mobile device, the light measurement having a spectral response; receiving a location and a time associated with the light measurement; providing a spectral correction factor appropriate to the location and the time associated with the light measure; scaling the light measurement by the spectral correction factor to obtain a target measure; detecting light within two or more differing fields of view with at least one secondary sensor of the mobile device, wherein the two or more differing fields of view are at least partially defined by at least one shielding structure disposed between the first sensor and the at least one secondary sensor, wherein the at least one shielding structure covers a partial portion of a sensor area of the at least one secondary sensor; and scaling the light measurement with a correction factor based upon the light detected within the two or more differing fields of view, wherein the correction factor is determined based on levels of the light detected within respective ones of the two or more differing fields of view relative to a level of light detected within a first field of view of the first sensor.
