Demand for camera cell phones is increasing rapidly not only in Japan, but in most markets around the world as well.
While compact, high image quality cameras are in demand in the cell phone market, there are also increasing desires for high-
level camera functions such as mechanical shutters and autofocus.
SANYO developed even further their motor driver technologies nurtured through years of experience in the digital camera field
and provides these technologies for use in camera cell phones as ultraminiature package motor drivers that require few external
components.
