Irvine, Calif. Carving out a new niche in the mobile phone market, Samsung Electro-Mechanics (SEM) has developed an unique device, designated as the auto camera drive (ACD), that rotates the camera on a mobile phone with the push of a button. Typically, users of camera phones have had to manually rotate the camera in order to change the screen from landscape to portrait; however, the new ACD promises to do the job automatically.
Based on micro-geared motors and a precision mechanism technology, the ACD provides a rotation time of 0.5 seconds and operates at 60 mA, which is at least 40% less power than that consumed by vibration motors, said the company. It also exhibits low noise operation at 30 db and features a cycle life of 70,000 cycles.
The ACD can be designed as a single unit with the camera module or as a separate unit, depending on the mobile phone design such as bar, folder and slide form factors.
The first consideration in the camera phone market has been resolution, said the company, and as soon as all camera modules offer the same picture quality, the ACD can offer an additional incentive for purchasing a given model.
The company says it will continue to acquire new technologies that will make the device smaller and extend the product life as well as enhance reliability.
The average starting price for the ACD is around $4, depending on function and specification. The company can typically deliver a component design and samples in two to three months.
