1. An image sensor system, comprising: a meter sensor comprising pixels that are arranged to produce a meter image that includes color information for pixels in the meter image, wherein the meter sensor has associated meter sensor color calibration information of a calibration image that includes monochromatic information that is sequentially illuminated by light sources having differing color temperatures; an image sensor comprising pixels that are arranged to produce an captured image that includes color information for pixels in the captured image, wherein the image sensor has associated image sensor color calibration information of the calibration image that includes monochromatic information that is sequentially illuminated by light sources having differing color temperatures; and processing logic that is arranged to determine a white balancing point for balancing a secondary image of an illuminated scene captured by the image sensor, wherein the white balancing point is determined in response to the meter sensor color calibration information, the image sensor color calibration information, and color information from a secondary meter sensor image produced by the meter sensor capturing the illuminated scene.
