A technique of processing an image data for output on a digital image device that compresses () a portion of a received image data to a data frame () according to a predefined size that is optimized for output with a processor of the device. The portion of the image data that is defined by the data frame is outputted () to another source, and for any empty bits in the data frame, a zero bit is inserted ().

Method and apparatus for processing an image data for output

A bi-directional voltage translator (125) has a first port (201) that communicates a signal at a first voltage level, and second port (202) that communicates a signal at a second voltage level different from the first voltage level. A switching circuit, including a bipolar junction transistor (210) and a switch (220), couples both ports (201, 202). The transistor (210) has a collector (211) coupled, via a pull-up circuit (206), to a voltage source corresponding to the first voltage level, and to the first port (201), and an emitter (212) coupled to the second port. The base (213) of the transistor (210) is coupled, via a pull-up circuit (207), to a voltage source corresponding to the second voltage level. Preferably, the switch (220) is Schottky diode or other diode having a forward voltage drop.
