Camera phone use is becoming more widespread in Japan and throughout the world. As mobile phones continue to evolve into information terminals, the camera functions on mobile phones are used not only to take conventional photographs, but also to shoot pictures of detailed text such as train timetables, as well as to read two-dimensional bar codes. At the same time, mobile phone cameras have increasingly high resolutions for more beautiful pictures, and some camera phones with pixel numbers on par with digital cameras have appeared on the market.
In light of this trend, Alps led the industry in developing three camera modules of the same compact casing size ( 8.5mm wide x 8.5mm deep x 6.1mm high ). The modules feature fixed focus, macro facility and autofocus respectively.
Previously, camera phone modules varied in size according to their functions. To create the macro facility and autofocus functions, parts such as actuators that manipulate lenses in order to adjust focus had to be attached to fixed-focus camera modules, which served as the base. This meant that the modules themselves had to be made larger. By leveraging its high-precision processing and packaging technologies, Alps has enabled mobile phone manufacturers to choose between three focus functions all packaged in the same compact casing size. This contributes to a more diverse selection of mobile phones for users.
Lenses are the major component of camera modules. By employing its optical design technology, Alps has already developed high-resolution, aspheric plastic lenses that are thin and compact. Alps is thereby meeting the needs for higher-resolution, more attractive picture taking.
Actuators are needed to manipulate lenses for focus functions. Alps has created actuators that maximize the capacity of macro facility and autofocus functions. Alps employs a voice coil system that uses magnetic simulation technology for macro facility, and a piezo system for autofocus.
