Samsung Electronics Co., Ltd., has completed the development of its new S5K2E1FX, a CMOS image sensor (CIS) with 5 megapixel (2,608 x 1,952 pixels) QSXGA resolution.
Samsung's 5megapixel CIS performs at the same level as its charge-coupled device (CCD) counterpart, yet it operates on less power and the company says it is more price competitive. Samsung sees this new CIS being used on mobile phones as well as on digital cameras and digital camcorders.
The new CIS has a 1/2.5-inch lens aperture with a pixel measurement of 2.2 by 2.2 microns. Using 0.13-micron process technology, Samsung has increased the fill factor (the image sensor's measurement of light sensitivity) by over 50 percent.
It also has a footprint at least 30 percent smaller than other models of the same resolution. This allows the camera module to be designed into ever-smaller camera phones.
A sub-sampling function that shoots VGA quality moving pictures at 30 frames per second with no deterioration of picture quality has also been incorporated to shoot faster high-resolution images. Power consumption has been minimized as well to prolong battery life.
Another model is also being annonced, with a 3.2 megapixel for camera phones. S5K3C1FX has pixels that measure 2.25 by 2.25 microns in a 1/3-inch lens aperture with serial interface applied for accelerated data processing speeds.
Market analyst firm Gartner Dataquest predicts that the global CIS market will increase from US$2.4 billion in 2004 to US$3.2 billion this year and surge to US$5.6 billion by 2008.
Samsung plans to begin mass-production of the 5 megapixel CIS in the fourth quarter of 2005 and the 3.2 megapixel CIS with an embedded image signal processor (ISP) by the first half of 2006.
