Inch Ccd Cctv
in cctv cameras what does CCD sizes, such as 1/4 inch, 1/3inch mean?
These are the physical dimensions of the image sensor, or CCD. Generally, larger CCDs offer better performance. Earlier in this review, we promised readers a look at the CMOS image sensor used in Canon's EOS D30 digital camera. This is certainly not a standard section in our reviews, but we felt that Canon's choice of CMOS was very significant! To understand what CMOS sensor technology can bring to a digital camera, first of all you need some understanding of how CCD and CMOS sensors work, and what they do differently.
CCD, or Charge-Coupled Device image sensors, were invented at the end of the 1960s by scientists at Bell Labs, and were originally conceived not as a method of capturing photographic images, but as a way of storing computer data. Obviously this idea didn't catch on; today we instead have RAM (Random Access Memory) chips in our computers which are, ironically enough, manufactured using the CMOS process.
Where CCDs did catch on, however was recording images — by 1975 CCDs were appearing in television cameras and flatbed scanners. The mid 80s saw CCDs appearing in the first "filmless" still cameras… CCDs rapidly attained great image quality, but they weren't perfect. Perhaps most significantly, CCDs required a manufacturing process which was different to that used for manufacturing other computer chips such as processors and RAM. This means that specialized CCD fabs have to be constructed, and they cannot be used for making other components, making CCDs inherently more expensive.
Interline Transfer CCDs consist of many MOS (Metal Oxide Semiconductor) capacitors arranged in a pattern, usually in a square grid, which can capture and convert light photons to electrical charge, storing this charge before transferring it for processing by supporting chips. To record color information, colored filters are placed over each individual light receptor making it sensitive to only one light color (generally, Red, Green and Blue filters are used, but this is not always the case). This gives a value for one color at each pixel, and the surrounding pixels can provide eight more values, four each of the two remaining colors from which they may be interpolated for our original pixel.
