Ken Rockwell skriver om Canon S90, se länk nedan, där han uttalar sig om CCD vs CMOS.
"en riktig CCD, inte bara en CMOS"
"men tekniskt är CCD överlägsna CMOS"

Sensor 1/1.7." 10MP
Real CCD, not just CMOS.
Not that I've ever seen any visible performance difference in my back-to-back tests, but technically CCDs are superior to CMOS.
CMOS is less expensive to manufacture and therefore pushed more by camera companies because CMOS also allows more kinds of circuitry to be crammed on the image sensor. This saves camera makers a few chips and dollars over doing it right with a dedicated CCD image sensor and outboard sample and holds, analog-to-digital converters and DSP.
Finns det någon som vill göra en teknisk djupdykning i detta ämne?
