Operation

TM-6760 Series Progressive Scan Shutter Cameras

3.9 Scan Modes

The TM-6760 supports the following scan modes:

3.9.1 Full Progressive Scan

The normal scan mode progressively scans a full frame of 648 x 484 pixels at 30/60 frames per second

using the standard 12.5MHz/25MHz pixel clock and a single channel output. In contrast to interlace-

scan cameras, all 484 lines in the frame are exposed simultaneously per image capture.

3.9.2 Partial Scan

Partial scan is a standard feature in the TM-6760. 200 lines partial scan is selectable. It outputs an image

center of 200 lines. The frame rate is 120 frames/sec.

3.9.3 Two-Row Binning

Two-row binning is a standard feature in the TM-6760. It is selectable and its frame rate is 120 frames

per second.

3.10 External Sync and Pixel Locking

The TM-6760 accepts an external sync of standard HD and VD at TTL level for general locking to a

system sync and clock. The external sync is only available for 60-frame mode and the frequency

requirement is as follows:

fHD = 31.486 KHz ±5%

fVD = 60.00 Hz ± 5%

(Internal Master clock = 50.00 MHz,

Pixel clock = 25.00 MHz)
