3-2-4 CMOS sensor
The image sensors of camcorders can roughly be divided into CMOS (complementary metal oxide
semiconductor) and CCD (charge coupled device).
The table below compares the major features of CMOS and CCD sensors:
*6: The CMOS sensor in DZ-BD7HA/BD70A outputs digital signals. Some CMOS sensors in other products
may output analog signals.
