TS-2030EN/TS-2076EN Series Progressive Scan Cameras
Camera Features
Because the TSC-2030EN/TSC-2076EN does not contain internal color-processing circuitry, viewer software
must perform color interpolation on host PC side. The EN setup software supports color interpolation.
After color interpolation, white balance must be properly done. Otherwise, gray or white objects cannot be seen
as gray or white. Each TSC-2030EN/TSC-2076EN (color) camera is calibrated in simulated daytime condition
and each image (TIF/JPEG) transferred to host PC contains Rgain and Bgain with regard to Green. By decoding
TIF/JPEG header, Viewer software can properly perform white balance. Please refer to "LC To EN Interface
Document" (Doc number 69-1198) for more information (color).
Please note that the factory default setting of the TSC-2030EN/TSC-2076EN (color) turns off Gamma correction,
because the non-linearity of the Gamma response curve degrades white balancing. Only linear LUT is used.
Also, it is important to keep in mind that a lossy JPEG encoding will cause color information loss. Viewer
software cannot reconstruct the color image properly after it has been encoded to JPEG format. In order to
reconstruct the color properly, users must use the raw TIF image format only.
6.7 Image Formats
Two image formats are supported; TIF and JPEG.
The TIF Format image is always ON, and users cannot turn it off. "Image Acquisition 1" and "Image
Acquisition 2" config registers (Address = 3 and 9, respectively) control which image format to choose. Multiple
image formats, such as both TIF and JPEG, can be selected.
Whether you choose TIF or JPEG format, images sent by the EN cameras contain additional information other
than just pixel information. TIF/JPEG header includes ADR information (shutter, gain, Vtop, Vbottom),
TimeStamps, Network setting (IP address, MAC address), Error status, and much more. Please refer to the "LC
to EN Interface" document for details concerning TIF tagging.
6.7.1 TIF Format
The uncompressed (or raw) TIF format is the best choice to maintain the accuracy of the pixel information for
further image analysis and processing.
For the TSC-2030EN/TSC-2076EN (color) model, the user should deal only with the TIF format image,
because detailed color pixel information will be lost in the JPEG format image.
Please refer to the "LC to EN Interface" document for the detailed TIF header.
6.7.2 JPEG Format
JPEG is the industry-standard format for lossy image compression. Output file size, quality and speed of the
encoding depends on the quality setting. The user can set the proper quality setting by accessing the "JPEG
Quality Factor" config register (Address = 46). The factory default is 85.
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.
