Sony Corporation Annual Report 2002
Network Handycam
No other company comes close to Sony’s leading position in the world camcorder
market. Smaller size and lighter weight combined with greater network
affinity are defining features of the Network Handycam IP pictured
here. Making all this possible is Sony’s newly developed MICROMV
format, which is based on MPEG2 image compression technology.
This camcorder comes with Bluetooth™ wireless communication
capability installed. By connecting to the Internet with a Bluetooth™
modem adapter or a mobile phone, users can send and receive e-mails.
With video and still images saved on their Memory Stick, users can
easily create and view albums online, without connecting to a PC.
CCDs
Sony meets a high percentage of the global demand for CCDs (charge-coupled
devices), a component that functions as an “electronic eye.” Most often used in video
cameras and digital still cameras, CCDs are now increasingly employed in mobile
phones, PDAs and other electronics products.
As digital still cameras become more compact, the surface area of the CCDs
contained within cameras has also shrunk. This means that the surface area of each
pixel in a CCD has had to become smaller, and that the amount of light to which each
pixel is exposed has decreased. To deal with these challenges, Sony developed the Super
HAD CCD. This technology minimizes the unused space between the on-chip microlenses
on each pixel by optimizing the shape of these lenses. With this breakthrough, Sony has
been able to increase the light sensitivity per unit of surface area even though each
pixel is smaller.
In response to increasing demand for single-lens reflex digital still cameras, used by
the media and consumers alike, Sony developed a color CCD image sensor that is the
same size as APS film, pictured here. Because the imaging surface of this 1.8-inch CCD
is virtually equal to that of APS film, digital still
camera makers can utilize optical components used
in conventional film-based cameras, facilitating
effective design and efficient development of
products. The 6.15 million effective pixels and
superior sensitivity of this CCD yield pictures that
have the same sharpness and vividness as those
taken with conventional film.
