Operation

The following diagram is an example of the TMC-1400 (same as TM-1400).

1H = 32.16µsec.

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 A, if the first pixel is shifted (missed), the color interpolation should start with G-R. If the first line is missed in A, the interpolation order will be B-G.

3.9.5Camera 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When two rows are mixed in the CCD, the Bayer color is no longer valid.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 information but cannot be interpolated as a Bayer CFA.

•LUT (Look-up Table)

The 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.

For a detailed timing chart, please refer to the standard AccuPiXEL camera data sheet, or contact JAI PULNiX.
