Async Reset Mode: Mode 0: normal mode; Mode 1-4: fast mode;

Mode 5-8: slow mode; Mode 9: pulse width mode. At modes 1-9

the camera is at standby only, black video is output. One frame

image will be output upon receiving an async reset pulse.

Electr

onic Shutter

The TM-6710 has a substrate drain type shutter

mechanism which produces a superb picture at various

speeds without smearing. The built-in manual shutter

speed control selects the electronic shutter rate of

1/125, 1/250, 1/500, 1/1,000, 1/2,000, 1/4,000, 1/8,000,

1/16,000, or 1/32,000 sec. All shutter speeds are

applied to partial scan, except slow speed at partial

scanning. Progressive scanning allows a full 484 lines

of vertical resolution per single shutter, unlike a

conventional CCD camera at only 244 lines per shutter.

Partial Scanning

By setting the mode switch on the back plate and sending

the RS-232 command, the TM-6710 can have partial

scanning of 200 and100 lines (full resolution at narrower

field of view and faster frame rate).

Switch selection

Normal mode: F UP 120 Hz progressive scan

200 line scan: F DWN 240 Hz progressive scan

100 line scan: E UP 350 Hz progressive scan

(Special option: 2-row binning at 240 lines, 240 Hz)

The TM-6710 can accept external HD and VD for phase locking. The

internal PLL will accept external HD and lock with the CCD’s

horizontal drive (H

D). The CCD HD frequency is half of the analog

video output H

Example: Ext. HD = 30.49 kHz; VD will be 120 Hz and Master

Clock will be 50.90 mHz.

The internal sync generator will accept external V

D to generate internal

VD. The external VD frequency should be ±5% of the frame rate.
