Broadcast camera using digital signal processing

Realizing that it is unrealistic to convert the entire signal processing system to digital technology, the authors attempted and achieved the development of a signal processing method that would optimally combine analog and digital signal processing functions. This solves the digital accuracy problem, and combination of this system with a microcomputer based system control process improves the operational flexibility over that offered by analog signal processing methods. The digital signal processing system has been implemented by means of three newly developed LSIs. These LSIs incorporate a number of functions that cannot be realized by analog methods. Using these development, they have succeeded in producing the world´s first broadcast-quality TV camera that features digital signal processing and high-performance FIT-CCD in the image capture unit
