TransChip announced that it will demonstrate a variety of auto-focus and optical zoom AlgoCam TC7040 camera solutions at 3GSM World Congress this coming week in Barcelona, in Hall 2, booth E09/E10. TransChip's new auto focus and optical zoom features enable camera phones to achieve the same performance and picture quality that, to date, has only been attainable with digital still cameras.

TransChip will be demonstrating its auto-focus solutions using a number of different technologies, including:

• Voice-coil technology, using a NanoFocus' HYSonic actuator that offers high reliability with a small footprint
• Electro-wetting technology using the Varioptics Arctic liquid lens, which can focus at extremely close distances, such as 4 centimeters, with no moving parts
• Piezo electric technology using the Johnson Electric's NanoLens highly accurate actuator, which provides fast convergence in less than one second
• Piezo electric technology using 1's low power Helimorph actuator
• Extended focus technology, enabling all parts of image to be in focus without moving the lens.

TransChip's AlgoCam TC7040 contains an embedded control function, which enables the auto-focus solution to gather statistics on a raw captured image to determine the exact direction and distance by which the lens must be moved in order to achieve the sharpest image.

The company will also demonstrate an optical zoom feature of 3x, using Johnson Electric's NanoZoom lens module, which works in wide and tele-modes similar to digital still cameras.
