EN Camera Series
6.7.2JPEG Format
JPEG is the
Access to “Image Acquisition 1” and “Image Acquisition 2” config registers (Address = 3 and 9, respectively) and turn on JPEG format. Factory default setting is TIF format only.
If JPEG quality factor is high (above 85) and image contains complex detail information, the output file size of JPEG encoding becomes larger. JPEG image size must be properly defined in “Storage Setup” of JPEG. If the output file size exceeds the pr defined JPEG image size, the result JPEG image will not contain the full resolution of the image. Please refer to Section 6.9, “Image Buffering,” on page 44).
For the EN Camera (color) model, the user should not deal only with the JPEG format image, because this format will not retain detailed color pixel information.
Please refer to the “LC to EN Interface” document for details about the JPEG header.
6.8Image Transfer
6.8.1UDP Image Transfer on Setup Channel
The EN camera can send video images over TCP
UDP setup images are easy to enable and disable. The user can access the “EN Setup Trigger Source” register (Address = 111) and “EN Setup Image size” register (Address = 112) to change the trigger source and image size. Live image transfer can be slowed down by setting “EN Setup UDP
6.8.2TCP Message-Based Image Transfer on the Control Channel
Image transfer over TCP is intended for more secure image transfer. Even if the packet is corrupt, the TCP/IP mechanism automatically resends the missing/corrupt packets. Full size, Odd field, or Even field images are supported and both raw TIF images and compressed JPEG images are supported on TCP control channel.
Unlike the setup channel that can send only one
For detailed register and interface information, please refer to the “EN to LC Interface” document.
As a default, the EN setup software receives all images over UDP (setup channel). However, if you prefer to switch to TCP images, you can do so by enabling the "Use TCP/IP" option. This is under the "View" menu on the Video Window.
