Abstract
A method of manufacturing a digital video camera is provided. The method comprises acquiring video images of colored light, and measuring a light intensity response of the video camera to the colored light. The method further comprises comparing the intensity of the measured response to a desired colored light intensity for determining a color intensity bias and storing the intensity bias for the colored light in the camera so that the bias can be applied when the camera is operating at an arbitrary lighting condition.
