Abstract:
A video colposcope with a digital electronic color filter, said colposcope comprising:storage means for storing data defining a reference filter algorithm and color balance levels;a video camera for obtaining a subject electronic image of a subject object;color balancing digital processing circuitry for modifying color saturation, hue, and intensity levels of the subject electronic image according to the stored reference filter algorithm to produce a continuous real time modified electronic image corresponding to the subject electronic image; andoutput means for outputting said continuous real time modified electronic image to a display means in continuous real time as the corresponding subject electronic image is obtained by the video camera, wherein said color balancing digital processing circuitry includes means for producing said continuous real time modified electronic image that emulates a subject electronic image obtained through an optical green filter, said color balancing digital processing circuitry further including digital white balance circuitry means for continuously simulating in conjunction with said continuous real time modified electronic image, a continuous real time simulated white balanced electronic image in which a new white balance point is simulated in accordance with the continuous real time modified electronic image, and in which the new white balance point is centered on a detection window.
