Camera Features
TS-9720EN Series Progressive Scan Shutter Cameras
Because the color filter array contains only a single R, G or B color in each pixel, the restored image has
to fill in colors in the missing pixel locations. The software uses neighboring pixel information to
“guess” the missing colors to make smooth, clear images. This is called “color interpolation.”
Because the TS-9720EN 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 TS-9720EN 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.
Please note that the factory default setting of the TSC-9720EN 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-9720EN (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.
