Beginning with their adoption of cellular phones back

in 2002, Sony’s CMOS sensors for megapixel class

camera cell phones, and digital high definition video

cameras have become widely used in commercial products.

The greatest strength of the CMOS sensors is that

by including both digital and analog circuits on

the same chip, their readout speed can be made much

faster than the CCD. Sony is now developing high

speed CMOS sensors for digital cameras that will

provide continuous imaging from all pixels at an

amazing frame rate of 60 frames.

Here recently, the trend towards higher pixel counts

in consumer digital cameras have continued, and now

it’s possible to take high resolution still images

conveniently. Until now, Sony focused efforts in

the image sensor area on increasing the pixel count

and improving the characteristics of the pixels to

achieve high resolution imaging that everyone

loves about high definition video cameras.

Sony is also aiming for an image sensor that will

be able to capture and express surprise and emotion,

and is now putting efforts into a CMOS sensor that

can do just that.

Even through image quality will improve as you

increase the amount of information you capture, until

now, the still image quality of pictures has been

improved by spatial resolution increases. The

amount of information however, can be increased

not only by spatial resolution increases, but also

by increasing the amount of information in the

time direction as well.

If anything can be said about Sony technology, it

would be to never doubt it. Sony creates very amazing

products, and are among the leaders in camera

technology today. The CMOS sensor is just another

step for Sony in the world of high definition video

cameras, making it something you can’t go wrong with.
