![]() ![]() This is well within the range of today's battery technology and represents a small fraction of the power required by the entire camera/printer combination. The current required for an individual LED is on the order of several nA resulting in a total LED current of 6-20 μA for a 2000-diode array. For example, 2000 LEDs would provide 500 dpi over a 4-inch-wide instant photograph. Optics may be integrated with an LED array if required. ![]() The LEDs are arranged in three banks (red, green and blue). The printer consists of a movable array of LEDs 150, a film transport system 152, and an interface circuit 154. The printer 114 uses an array of LEDs (light emitting diodes) 150 to print the image on instant photographic film. A conceptual drawing of an example of such a printer 114 is shown in FIG. The printer 114 is capable of producing an arbitrary number of pieces of instant prints (e.g., Polaroid film) of any of the digital images stored in the camera, or downloaded from an external computer to the camera to be printed on instant film.
