San Jose, Calif. OSRAM Opto Semiconductors has expanded its infrared (IR) product portfolio with the addition of the SFH 7710 SMT orientation sensor for camera phones, digital cameras and personal data assistants (PDAs). The SFH 7710 detects whether a photo has been taken in portrait or landscape format and automatically displays the photo in its correct orientation, eliminating the need to rotate digital pictures in order to view them.
The company says the SFH 7710, which measures 4.4 x 4.4 x 1.8 mm high, is the first optical orientation sensor of this size in SMT technology. It is housed in a plastic package and is suitable for standard solder processes. Said to be more cost-effective than existing microelectromechanical system (MEMS) sensors, and with very low power consumption, it is suitable for use in mobile terminals such as mobile phones, PDAs and digital cameras.
The SFH 7710 orientation sensor operates on a supply voltage of 2.5 V and has a current draw of less than 50 microamps on average. The sensor has an integrated light barrier comprised of an IR emitter and a detector. The device is lead free and RoHS compliant.
How it works: In the detection field of the light barrier there will be an object in either portrait or landscape format depending on the orientation of the mobile terminal. When the terminal is rotated, the object will move out of the detection field of the light barrier. The sensor sends the information indicating whether the object is inside or outside the detection area as a unique signal via a digital output. Appropriate software then processes the signal and rotates the contents of the display to the correct orientation. There is no need to flip or rotate the image after downloading.

The SFH 7710 is expected to be available in January 2007. Pricing is $0.99 each in low volume. Delivery is approximately eight to ten weeks.
