Sanyo VCC-3944 Brochure - Page 2

VCC-3944 • Built in DSP (digital signal processing) circuitry • 1/4" CCD image sensor with approx. 270,000 picture elements • High sensitivity, minimum required illumination of 0.3 lx with F1.2 lens (Gain: HI) • More than 350 TV lines of horizontal resolution • Two types of backlight compensation Multi-spot photometry (64-section) system The screen is divided into 64 areas on which luminous intensity is measured separately to determine the lighting/backlight conditions of all objects. This makes it possible to apply optimum backlight compensation even for peripheral objects and moving objects. Multi-spot photometry Center-zone light measuring system The brightness of the central area of the picture frame is measured, and by automatic adjustment of the lens aperture a clear and sharp image is possible even when the subject is backlit. • Auto tracing white-balance / Manual white-balance • Electronic iris (indoor use) • 24 V AC and 12 V DC, dual power operation MODEL VCC-3944 Scanning system NTSC standard 525 lines, 30 frames/sec.
