主题：【讨论】CANON 又胜　NIKON　一轮 -- karman

Until recently, almost all compact (small sensored) cameras were built around CCD sensors. This is because CMOS sensors have more circuitry built into the chip than CCD sensors and, with less room for actually capturing light, noise and noise reduction issues will have a detrimental effect on image quality.

Manufacturers have been working on these problems with CMOS sensors for a number of years in DSLR cameras, where all but the cheapest models feature CMOS sensors. Canon, which has been at the forefront of this CMOS sensor development, released the CMOS-sensored SX1 IS which we reviewed last month. Given Sony's heavy involvement in the sensor design and fabrication industry it is not surprising that it has followed suit with the CMOS based HX1.
