Patent ID: 8049812

Claim:
A camera system comprising: a camera having a lens, the camera having an auto focus mode, wherein the auto focus mode relies upon a first wavelength or first range of wavelengths of light to automatically focus the camera to a first focus setting; a range sensor that is configured to determine a range between a subject and the camera; an offset computation module that determines an offset value based at least in part on the range between the subject and the camera determined by the range sensor, the offset value being effective for correcting focus of the camera from the first focus setting at the first wavelength or first range of wavelengths of light to a second focus setting at a second wavelength or second range of wavelengths of light; and a focus actuator configured to adjust a focus setting of the camera in accordance with the offset value to the second focus setting, the second focus setting being used in capturing an image of the subject using the second wavelength or second range of wavelengths of light.
