|ALPS develops two new 1.3 MP modules for mobiles|

ALPS has developed two new 1.3 Megapixel camera modules for mobile telephones: the FPDF0X series, and the FPDF8X series with autofocus. Sample shipments of the FPDF0X series will commence in July 2004, those of the FPDF8X in August. Recently, there has been an advancing trend toward the incorporation of cameras into mobile telephone, notebook personal computers, PDAs and other compact mobile devices. This has been particularly prominent in the case of camera-equipped mobile telephones, and of all mobile telephones that will ship worldwide in 2004, approximately one fourth, some 150 million units, will be equipped with cameras (Source: InfoTrends Research Group, Inc. of the U.S.). Rapid growth in demand for camera modules is forecast. |
The capabilities of mobile telephone cameras have also been significantly enhanced. Image quality has soared as Megapixel-level resolution rises, while auto focus and exposure adjustment functions have become commonplace. Accordingly, there is demand for camera modules that are compact and slim, offer high image quality, and feature multiple functions.|
These two series represent ALPS' response to these market needs.
Employing its proprietary optical design and aspherical moulded glass lens technologies, ALPS developed a high-precision F2.8 lens for both the FPDF0X and FPDF8X series. This lens, together with optical and mechanical design that elicits maximum performance from a 1.3 Megapixel CMOS sensor, is responsible for the high image quality achieved.
The FPDF8X series of camera modules with auto focus function incorporate a stepping motor developed using ALPS' original cutting and mold-machining technology. Lens movement is 394µm total in 35 steps of 11.25µm. This system offers precise focusing at all settings from infinity to macro. In addition, an integral digital signal processor and algorithm for image processing make linear auto focus possible, for easy photography of everything from close-ups to full figure portraiture and landscapes. Further, lens position is maintained even when power drops to zero, which contributes to the power conservation so desired in mobile telephones and other compact, portable devices.
In response to the ongoing reduction in the size of electronic devices, the FPDF0X series has dimensions of 10.0×10.0×8.5(mm), for a volume of 0.85ml, the FPDF8X series 14.9×14.9×9.0(mm), for a volume of 1.99ml. The FPDF8X series are the world's smallest camera modules offering 1.3 Megapixel resolution and auto focus.
This market is forecast to continue expanding, and ALPS will continue developing new camera modules for mobile telephones and other compact mobile devices. Two-megapixel resolution, optical zoom and shutter action, and other features are in development, as ALPS leads the way to higher resolution and functionality.
Two series of compact, slim, 1. 3 megapixel camera modules have been developed:
The FPDF0X series
1. Employing proprietary optical design and aspherical molded glass lens technologies, ALPS developed a high-precision F2.8 lens.
2. High image quality was achieved through optical and mechanical design that elicits the full capabilities of the CMOS sensor.
The FPDF8X series with autofocus
1. Proprietary stepping motor allows precision lens movement control in 35 steps of 11.25µm.
2. Lens position is maintained even when power drops to zero.
Compact mobile devices, including mobile telephones, PDAs, and computer peripherals.
