No-Delay Shutter and Read-Out Inhibit

The TM-1020A series also has read-out-inhibit control (ROI) to control the vertical clock start (Async
Shutter #9). When ROI is low, V-clock is stopped and the transferred charges remain in the vertical shift
registers, which work like CCD memory. When the ROI is high, it clocks out the CCD data. This helps
a single frame grabber process multiple images in pipeline processing (sequential process).
