Outstanding Features
■Resolution
Horizontal resolution of 750 / 900 TV lines is achieved by the 2/3 inch 600,000 / 620,000 pixel CCDs with microlenses and digital double speed signal processing circuit.
■Switchable 16:9 / 4:3 (V-21W only)
The aspect vatio is switchable between 16:9 and 4:3
to provide broad freedom for program production. Picture quality is also preserved by using digital system.
■Newly crafted DSP
Hitachi's pinnacle holding LSI technology combines the entire system from processor to encoder into a single chip to even further reduce the size and power consumption, while enhancing stability.
The 10 bit A/D converter and 13 to 18 bit processor promote high S/N and wide dynamic range.
■Signal to noise ratio
An S/N rating of 63 dB is attained by adding low noise circuit technology to a newly developed digital noise reduction circuit. Even at high gain, clear low noise images can be obtained.
■ Sensitivity (standard 2000 lux, F11)
High gain (+24 dB) and
0.8 lux (F1.8).
■Setup card
Camera setup data can be saved to a setup card (Compact Flash) and recalled when required. Flexibility is offered to meet a wide assortment of scene environments.
■Versatile CCD drive functions
●Preset type
●Lock Scan to image computer monitors without flicker.
●Auto electronic shutter (AES) mode for maintaining a fixed video level.
●CC frame mode for improved vertical resolution.
■Better picture quality from digital processing
●Highlight chroma and auto knee
Color reproduction of highly luminous signals is improved by the highlight chroma circuit, while auto knee automatically compresses high luminosity signals. These add up to wide dynamic range.
●Flesh tone detail
Smoothed and softened complexion flatters the talent without sacrificing overall scene detail
●Variable detail boost frequency
The center frequency of the detail compensation signal is variable to allow selecting the proper signal to match the scene.
●
Full colorimetry control is built in with linear matrix compensation for color reproduction plus independently variable hue and saturation for six colors to provide wide latitude for subjective expression
●Special gamma
Adjusts the gamma rising gain to improve reproduction of dark scene components.
●Flare compensation
