We will also strengthen and advance our differentiated technologies and core devices -- sources of our competitive advantages in electronics -- as another focus area of growth going forward.
The HDR-XR520V and HDR-XR500V Handycam® camcorders introduced in 2009 succeeded in setting Sony further apart from other video camera brands. These models were the world's first consumer models mounted with the "Exmor R™" back-illuminated complementary metal oxide semiconductor (CMOS) image sensor,* which achieves increased sensitivity and reduced picture noise. Subsequent Handycam® video cameras and Cyber-shot™ compact digital cameras also used this image sensor. Sony's digital imaging business contributes substantially to Sony's results and its products, including the NEX-5 and NEX-3 interchangeable lens digital cameras, earned considerable acclaim -- including the Nihon Keizai Shimbun Awards top prize in the Nikkei Superior Products and Services Awards for the past two consecutive years.
We also supply image sensors to other digital camera and cell phone manufacturers around the world. Our quick responses to feedback from these companies allow us to maintain a high level of competitiveness, and help to ensure that we keep our top market share in image sensors. Looking ahead, we are responding to the rapid growth in the market for smartphones by investing decisively in CMOS image sensors to expand our production capacity and revolutionize our technologies, with the aim of further bolstering profits.
Sony is also accelerating the growth and differentiation of our professional-use camera business by developing content creation products and security cameras that integrate our latest proprietary technologies into our image sensor and component businesses.
In addition, Sony's digital cinema projectors, which I mentioned earlier, display 3D images in high quality through the use of SXRD™ (Silicon X-tal Reflective Display), Sony's proprietary high-resolution and high-speed response display technology.
We also intend to leverage these and other technologies to foster new businesses within the growing energy and medical fields.
