Abstract
Systems and methods are provided for calibrating a digital camera. First pixel values of a first calibration image illuminated by white light are captured using a color sensor. A color sensor adjustment matrix is determined based on a comparison of the first pixel values and baseline pixel values associated with the calibration image. Second pixel values of a second calibration image illuminated by a first color temperature light are captured. The second pixel values are adjusted based on the color sensor adjustment matrix, and a first color temperature balance factor is determined based on the adjusted second pixel values, where a white balance adjustment is performed on captured image data based on the first color temperature balance factor.
