OPERATION

TM-6703 Progressive Scan Double Speed Shutter Camera Page 11

3.1.3 Shutter Control Switch

The shutter control switch is located on the rear panel of the camera. The dial can be

set from 0 to 9. The settings are detailed below.

Mode 0: Normal Mode

Mode 1-4: Fast Mode

Mode 5-8: Slow Mode

Mode 9: Pulse Width Mode

Note: Manual shutter speeds lower than 1/1,000 (i.e., longer in duration) are not applicable for

partial scan due to the short frame rate.

3.1.3 (a) External Pulse Width Control Mode

To select the External Pulse Width Control mode, set the shutter speed dial switch to “9”. Apply a pulse

width control VINIT signal to the camera via an external event trigger. The internal reset pulse will be

latched to HD. At the 9th HD timing from the external pulse leading edge (negative going edge), the

CCD discharge pulse will be generated to clear the images. The internal VD is generated at the

following edge (positive going edge) of the external pulse, and resets the internal timing, including the

video sync.

The shutter speed will be the same as the external pulse width, but the integration delays 9H from the

leading edge of the external pulse width. For the immediate reset option, please contact PULNiX.

One frame of video output will start from the rising edge of the pulse width control for progressive

format. The camera will output the same video from memory when VINIT is kept high (5V), and update

the image upon receiving the next pulse. At async mode, with external pulse input high, the video output

is disabled as the camera keeps discharging the CCD image and only will provide black video.
