Functions and Operations

TM/TMC-4200CL Series Progressive Scan Cameras

6.4 Electronic Shutter

The TM-4200CL has a substrate drain-type shutter mechanism which provides a superb picture at 
various speeds. 

6.4.1 Preset Shutter

TABLE 4.

Electronic Preset Shutter

6.4.2 Programmable Exposure-Continuous Mode

The exposure time of TM-4200CL can be specified from one video line to a maximum of one frame 
using the serial communication commands in the Continuous Mode. There is overhead where the 
specified exposure time is 

n

 video lines, making the real exposure time equal to

When 

n

=0, the exposure time is the minimum exposure time. It is equal to:

In this mode the maximum exposure time is equal to the setting for one frame. If the user specified 
exposure time is longer than the time allowed for one frame, it will be ignored by the camera.

6.4.3 Asynchronous No Shutter Mode

In Asynchronous No Shutter Mode, applying the external trigger starts a camera scan reset. The camera 
finishes the line it is scanning and scans an additional  9 video lines, this charge is sent to the horizontal 
register. 

Because the external trigger is randomly applied, the new image charge may overlap with the previous 
image. To prevent an existing charge accumulation from interfering with a new image, most users set up
