LIVE MOS e съвсем нов тип сензор
MOS vs CMOS vs CCD
When i first read about the 3-MOS technology in the new AG-HPX300 camera, i was sure that there was a typographical error in the literature, then i started to do some digging.
here i what i learned:
Image sensors for video and still cameras have been traditionally of the CCD or CMOS variety.
the CCD offers high light sensitivity and little noise but has poor color reproduction which is why camera manufactures use 3 to image the RED, GREEN and BLUE respectively. the CCD uses more power than a CMOS sensor so a battery time can be shorter.
The CMOS sensor uses less power than the CCD sensor and is good at rendering color information, the CMOS sensor is cheap to make too, this makes the CMOS sensor ideal for consumer grade cameras. the major draw back to the CMOS sensor is the fact that because of the architecture, the sensor is not as sensitive to light as the CCD so you have to have a bigger CMOS sensor to equal the light sensitivity of the CCD type.
The CMOS sensor has a noisy background, this can preclude the use of this sensor in high end broadcast cameras.
so a very cool new sensor has been developed, one that is more sensitive to light and color than the CCD, has the same power consumption as the CMOS, and does not have the "noisyness" of the CMOS sensor. This image sensor has been developed in conjunction with Panasonic and is being utilized in the newest Panasonic broadcast and other manufacturer digital SLR cameras with the Live MOS Sensor.
