3.7 Scan Modes
The TM-1402 supports the following scan modes:
3.7.1 Full Progressive Scan
The normal scan mode progressively scans a full frame of 1392 x 1040 pixels at 15/30 frames per
second using the standard 25MHz/50MHz pixel clock and a single channel output. In contrast to
interlace-scan cameras, all of the 1040 lines in the frame are exposed simultaneously per image capture.
3.7.2 Partial Scan
Partial scan is a standard feature in the TM-1402. The TM-1402 has two types of partial scan modes:
500 and 250 lines. Both modes can be selected through software control. The video image in partial
scan mode is the center 500 or 250 lines of video. The maximum frame rate at 500 lines is 56 fps. The
maximum frame rate at 250 lines is 98 fps.
3.8 External Sync
The TM-1402 accepts an external sync of standard HD and VD at TTL level for general locking to a
system sync and clock. The external sync frequency requirement is as follows:
3.9 Bayer Color Filter (Color Versions)
JAI PULNiX AccuPiXEL series color cameras are high-resolution, high-speed progressive scan CCD
cameras. The interline transfer, progressive scan CCD permits full vertical and horizontal resolution of
images acquired at very high shutter speeds. The electronic shutter, which has speeds to
