The XC-777/777P is the 1/3-inch IT CCD miniaturized version of the XC-999/999P, developed for applications where the size of the 1/2-inch camera is a restriction. The unit provides the same high quality images as the XC-999/999P, but in a substantially reduced package.
Low weight and power consumption make this unit ideal when these factors are critical - such as in battery-powered vehicles. Camera XC-777 (XC-777P) works in accordance with EIA (CCIR) video norm, using NTSC (PAL) color coding system.
Single-piece camera, no separate CCU
Composite, Y/C (S-video) outputs
Auto Tracing White (ATW) and manual white balance
Compact design: 22×22×89 mm, 75 g
2. Main features
Most features are compatible with the XC-999/999P
Several electronic shutter modes, featured by the XC-777/777P cameras, allow user to control the exposure time according to the current working conditions.
Shutter off mode, intended for capturing still objects.
A standard electronic shutter with shutter speeds 1/1 000 sec and 1/4 000 sec.
For suppressing the flicker of light (illuminating the captured scene) produced depending upon the frequency of the power source. The shutter speed is 1/100 sec for thee 50 Hz area and 1/120 sec for the 60 Hz area.
The color separation is in the 1-chip XC-777/777P camera achieved by complementary color mosaic filter.
According to the lighting conditions the XC-777/777P may operate in three different white balance modes: fixed (3200 or 5600 K), ATW (auto tracing white balance) and manual (by adjusting red and blue colors).
The camera's read-out process is controlled by internally generated synchronization. No external sync is available.
Scanning system (interlaced)
The camera operates in standard 2:1 interlace mode.
Full frame image is split into two fields: odd (lines 1-3-5...) and even (2-4-6...). It enables higher image resolution, but two steps (2 · 1/60 = 1/30 sec or 2 · 1/50 = 1/25 sec for CCIR) are necessary to read out full frame data. Period of VD signal is V = (A + 1/2)H in this mode, Ais an integer.
The XC-777/777P camera provides a 12-pin multiconnector to output the generated video signal, VBS or Y/C, 1 Vp-p, 75 ohm (the connector serves also as power input).
The other, 3-pin connector connects the auto iris lens.
