ADAPTIVE CAMERA WHITE BALANCE SYSTEM AND METHOD

摘要

A method for color correction in a camera system having a camera, a light source and a controller, the method comprising: setting a first light source drive current level; performing a first white balance operation and obtaining at least one of red gain, blue gain and green gain values corresponding to the first light source drive current level; setting a second light source drive current level different than the first light source drive current level; performing a second white balance operation and obtaining at least one of red gain, blue gain and green gain values corresponding to the second light source drive current level; and determining a relationship between light source current levels and at least one of red gain, blue gain and green gain values using the obtained at least one of red gain, blue gain and green gain values corresponding to the first and second light source drive current levels.

1. A method for color correction in a camera system having a camera, a light source and a controller, the method comprising:
setting a first light source drive current level; performing a first white balance operation and obtaining at least one of red gain, blue gain and green gain values corresponding to the first light source drive current level; setting a second light source drive current level different than the first light source drive current level; performing a second white balance operation and obtaining at least one of red gain, blue gain and green gain values corresponding to the second light source drive current level; and determining a relationship between light source current levels and at least one of red gain, blue gain and green gain values using the obtained at least one of red gain, blue gain and green gain values corresponding to the first and second light source drive current levels.
