im thinking of buying a digital imager.. but i dont know where to choose; look at billboards, tech magazines and others, theres a lot of digital techs that you can choose from and also added tons of digital imaging company… like where im working now.. whoaaaa!!!! monthly they produce new products and publish it in internet, highly rank magazines, email spamming, etc…(this is what i do actually). having the chance to work in a company that have the same line of business i got ideas on how to choose an digital imager!!…
first thing first.. oohh i like this digital camera… oohh i like this video camera…oohh i like this i like that.. then you asked for the price.. whoaa!! expensive….then sees the megapixel of the camera.. ooohhh 4.0, 5.0, 6.0….cybershot… what actually the differences of this.. thats what we where looking for…
theres a true 4.0 CCD megapixel video camera with 6 in 1 functions and theres a 5.0 CMOS megapixel video camera with 8 in 1 functions…as you can see theres a big differences with this two.. i am not talking about the functions neither the numeric value of the pixel. The main topic here is the differences of a CCD (charge coupled device) and a CMOS (complementary metal oxide semiconductor).
"CMOS imagers offer superior integration,power dissipation and system size at the expense of image quality (particularly in low light) and flexibility. They are the technology of choice for high-volume, spaceconstrained applications where image quality requirements are low. This makes them a natural fit for security cameras, PC videoconferencing, wireless handheld device videoconferencing, bar-code scanners, fax machines, consumer scanners, toys, biometrics and some automotive invehicle uses.
CCDs offer superior image quality and flexibility at the expense of system size. They remain the most suitable technology for high-end imaging applications, such as digital photography, broadcast television, high-performance industrial imaging, and most scientific and medical applications. Furthermore, flexibility means users can achieve greater system differentiation with CCDs than with CMOS imagers. Sustainable cost between the two technologies is approximately equal. This is a major contradiction to the traditional marketing pitch of virtually all of the solely CMOS imager companies." - excerpt from some research
