TM-6760 Series Progressive Scan Shutter Cameras
Operation
FIGURE 11. Sync and Data
It is important to meet the exact starting pixel at LDV and the starting line of FDV. If the starting pixel
or line is shifted due to the image capture configuration, then the interpolation software can be adjusted
for the correct starting point. In Figure 10 on page 24, left diagram, if the first pixel is shifted (missed),
the color interpolation should start with R-G. If the first line is missed, the interpolation order will be
B-G.
3.11.5 Camera Functions
AccuPiXEL color cameras perform all functions the same way as B/W cameras. However, because of
color characteristics, the following issues are different:
• Two-row binning scan
When two rows are mixed in the CCD, the Bayer color is no longer valid. It provides color infor-
mation but cannot be interpolated as a Bayer CFA.
• LUT (Look-up Table)
LUT is a powerful tool to adjust the dynamic range as well as color dynamic range. Since human
color perception is non-linear, LUT selection can help optimize color contrast by selecting the LUT
value. Gamma 0.45 is logarithmic and is closed to human perception.
When LUT is selected, black-level adjustment must be more accurate than for B/W cameras.
