Abstract: Driver current in digital retinal image transfer is significantly reduced for retinal cameras for reducing heat-induced dark current and resultant haze. In one embodiment line drivers are used whose current draw does not depend on data rate or frequency to eliminate the problem of high data rates creating high driver current draw.

The result is much lower overall clock driver current draw, less heat, less dark current and less haze.
