TM-1020 Series Progressive Scan Shutter Cameras
Operation
3.8.1 Full Progressive Scan
Normal scanning mode the TM-1020 series is for 1008 x 1018 pixels. The standard speed with single-
channel output is 15 frame/sec at the pixel clock of 20 MHz. The progressive scan reads every line from
top to bottom and, unique in an interlace-scan camera, all lines are obtained per image capturing with
electronic shutter.
3.8.2 Two-Row Binning
This is a standard feature in the TM-1020 series. The camera scans two rows together and outputs 1008
(H) x 509 (V) pixels at 30 frames per second. Two-row binning is typically implemented to increase
speed and to display real-time images on multi-sync monitors. When scan mode is changed from full
progressive scan to two-row binning, then the camera settings will default to those in page 1 settings.
3.9 External Sync and Pixel Locking
The TM-1020 series 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 not available in two-row binning and the frequency
requirement is as follows:
15 Frame/Sec Models: 30 Frame/Sec Models:
fHD = 15.734 KHz ±5% fHD = 31.47 KHz ±5%
fVD = 15.00 Hz ± 5% fVD = 30.00 Hz ± 5%
(Internal Master clock = 40.00 MHz, (Internal Master clock = 80.00 MHz,
Pixel clock = 20.00 MHz) Pixel clock = 40.00 MHz)
