able to obtain a highly-stable oscillating frequency that provides an accuracy of ±10 Pa*9 and a
resolution*10 of 0.1 Pa in a compact package that is only 12.5 cc and weighs only 15 g.
In the semiconductor business, Epson developed a 1/3-inch VGA HDR (High Dynamic Range) camera
that can record high-quality images without any pixel defects, even under lighting conditions with a 120
dB difference between light and dark areas. The image is taken with short, medium and long exposure plus
one for noise reduction and is then run through an image processing engine that uses Epson’ s original tone
mapping technology to give the image a greater sense of depth and to reduce the effects of camera shake.
A non-destructive readout enables the recording of objects in low-light situations and nearly real-time
output of HDR images at 30 fps (up to 120 fps with ordinary images).
*7 Adobe® RGB is a practical color space introduced by Adobe Systems Incorporated in 1998.
*8 QMEMS is a combination of “quartz,” a crystalline material that has excellent stability and precision,
and “MEMS,” micro electro-mechanical systems engineered using microfabrication technology. QMEMS
refers to compact, high-performance devices made from quartz material and is a registered trademark of
Epson Toyocom Corporation.
*9 Pa (Pascal) is the international unit for pressure.
*10 Resolution is the measurement or detection capability of a sensor or device.
*11 Absolute pressure is the pressure zero referenced against a perfect vacuum.

In the GPS (Global Positioning System) business, Epson worked with German chipmaker Infineon
Technologies to develop the XPOSYS™ product with next-generation A-GPS (Assisted-GPS) technology.
This product is optimized for mobile devices in the consumer marketplace, centering on mobile phones
with built-in navigation functionality. XPOSYS, designed on a 5 nm process, offers improved performance
and greatly increased sensitivity from -160 dBm to -165 dBm, enabling accurate positioning indoors and
around tall buildings. In addition, it extends the battery life of products by consuming 50% less power.
