Integrated Image Capture Timing
3.1.4 (c) Continuous Sync Output
When async reset is applied, video sync is also reset asynchronously. This phenomenon causes video
picture rolling or bouncing on the monitor. With this feature, a continuous output (no more bouncing or
rolling pictures) will be achieved at async reset.
3.1.5 Mode Control Functions
3.1.5 (a) 0. Normal Mode
The camera outputs real time normal video signal without electronic shutter or asynchronous functions.
The shutter speed is 1/12 sec.
3.1.5 (b) 1. MGC Gain Control
CDS amplifier gain can be controlled by the up/down switch. The minimum gain is 6dB and the
maximum gain is 24dB (factory set is 18 dB at power on).
3.1.5 (c) 2. Async / Manual Shutter Selection
The electronic shutter mode is selected by up (manual) and down (async) switch. When it is in manual
mode, the shutter speed is programmed by the shutter speed switch. When the async shutter is selected,
the shutter timing works with VINIT (async reset pulse). If VINIT is kept high, it keeps discharging the
CCD. When negative going pulse comes in, it resets the timing and captures a image, holding it until the
next pulse comes. The async shutter speed is also selected by the shutter selection switch but exposure
times are inverted from manual shutter times.
3.1.5 (d) 3. and 4. Gain Selection
Fixed specific gain is recalled by selecting 3 or 4 and pressing up/down switch up or down.
