Features
Digital processing
New Digital Processing ICs (ASIC) with 12 bit A/D
conversion is employed (internally up to 30bit
conversion). All the process after pre-knee is digitized,
providing stable and hi-quality pictures. Processes such
as Gamma and DTL signals are performed digitally with
up to 30-bit internal quantization, achieving superb
picture quality with good S/N in actual operation.
AIT Lower Smear-CCD (HC-D57W)
The HC-D57 employs high-performance 2/3" IT CCD with 410,000 pixels(NTSC) / 470,000 pixels(PAL). The
HC-D57W employs 2/3" AIT CCDs with 520,000 pixels(NTSC) / 600,000 pixels(PAL). The AIT CCD sensor
has less smear characteristics. It guarantees closer performance to FIT chip.
F11 Sensitivity
The sensitivity of F11 at 2000lux is realized. A greater depth-of-field facilitates simple focusing. Also vivid
images can be acquired even when the camera is used under low light condition.
Digital-Specific Versatile Videography
DTL function
Various DTL functions are incorporated such as Diagonal DTL, Soft DTL and Skin DTL.
Back-Light Compensation
The back light compensation function is incorporated in Auto-Iris mode. It guarantees proper operation of
the iris even in case of high contrast situation.
Black Stretch
The Black Stretch function improves the luminance reproduction shadow areas of the scene by raising the
video level only for low-brightness portion. The stretch level is variable in 3%, 5% and 7%
Normal
Black Stretch On (7%)
