K750i CCD vs. CMOS |

Quick summary of CCD and CMOS-
CCD/CMOS are simply sensors which turns light into electrons. The difference is that these two sensors process the electrons in a different way. With any digital camera CCD sensors are better, however CMOS sensors have their own advantages and are also becoming more advanced...
Visit these howstuffworks pages for a more in depth comparison between the two...

Not entirely true. Many SLR:s cameras e.g. from Canon uses CMOS instead of CCD and produces better pictures. Its all about how they are manufactured.

Thats why i put 'however CMOS sensors have their own advantages and are also becoming more advanced... '

Quite, and vitally and what everyone seems to forget is the optics are very important too. You can have as many megapixels and you like but if the optics aren't up to scratch - which they aren't on any camera phone then the pictures will still be pretty rubbish.
I don't understand the fuss people are making over this - firstly the "thumbnail" pictures as posted are as useless as a chocolate fireguard in getting any idea as the the difference in quality there really is no discernable difference between any of them that can't be put down to background conditions at the time. Second without decent optics in the lens the sensor type is really going to make very little difference anyway.
To be honest I can't believe SE are changing the sensor type in an existing phone like rumoured - it makes no sense whatsoever unless they are sourcing the new CCD parts significantly cheaper (has to account for production costs too) than the current CMOS parts which IMO seems unlikely. Personally I think they are just using the K750i shell as a prototype for upcoming phones which will feature the new sensor.

hmmm if this K750 w CCD use the same optics....then the comparison between CCD and CMOS can ignore the performance of optics
to me the current CMOS chip is very good.....especially for me who seldom use resolution over 1.2megapixel.
Too bad my testing of the device (CMOS version) is over....not stuck with my old T610....very sad....and I have regret to borrow it for one day.  |

Is the N90 ccd or cmos ?

N90: CMOS
K750i: anybody tried to change the plastic lens against a glass lens? |

Hey guys!!!
I just checked something!!
Look at the filenames of the pics on the first site of this thred!! The better pics (both time the second one) are the CMOS pics!!!!
Great!!
That means: we don't need to wait for CCD version aus this isn't that good as the CMOS version!!
This thread is the proove of what I always said....
The CCD pics have more noise (look at the red arount the Logo) and CMOS are more sharp: look at the chairs and look on the left site at the small product items which are sold there... |

I can't reveal too much but CMOS developement is still on going to match the quality of CCD when it come to product used for mid to low end product.
No doubt there's advantages to use CMOS for better picture quality beside the optics (lens) which is why we see some digital SLR is using it...but to date we didn't see very good CMOS for the mass market.
Just take some time and we should be able to see good CMOS chip.....the perception of CCD better than CMOS must be changed.......I used to believe CCD is better till I talk to a friend who is involved in company developing such thing.
BTW plastic lens will degrade the quality of picture taken...tht's why SE phone didn't have any plastic lens.
maybe one day they will do it like Nokia....put a carl-zeiss lens on the phone. |

Does that mean, that the K750i lens is of glass???
How about the K700i - is it glass, too?
Where did you get the info? |
