Patent ID: 7830424

Claim:
A method for reducing haze associated with the heating of sensor array elements in a digital CCD retinal camera coupled over a cable to a follow-on processor, comprising the steps of: providing a high resolution digital CCD retinal camera with line drivers whose current draw is both frequency-independent and minimalized; and providing a clock driver on a transmitting side driven by clock pulses from a free running clock coupled to an input of the clock driver, the clock driver being different from line drivers, the driving clock pulses input to the clock driver from the free running clock being inhibited by gating such that the coupling of the driving clock pulses to the input of the clock driver is inhibited until such time as the retinal camera outputs a retinal image, such that haze that is the result of dark current is limited by the frequency-independent low current draw of the line drivers and an intermittent current draw of the clock driver due to the gating of the driving clock pulse input thereto.
