10.2.5 Camera Functions
AccuPiXEL color cameras perform all functions the same way as monochrome cameras. However,
because of color characteristics, the LUT (Look-up Table) is different. 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 monochrome cameras.
10.2.6 Interpolation Software
The color interpolation can be performed in the frame grabber or by using the host computer’s CPU.
Most major frame grabbers with processing capability provide tools for color interpolation. Software
vision packages also provide color interpolation capability, but speed and performance may be deter-
mined by the PC’s resources and by the complexity of the interpolation routine.
10.2.7 Color Interpolation
The Bayer pattern color filter array (CFA) consists of R, G, and B primary colors. Each pixel represents
one of three colors. In order to display or print color images, the signal has to be converted to RGB
output, which has three independent channels (outputs) and sync signals.
Color interpolation software or firmware performs the color preprocess-
ing by filling the missing color pixels with neighboring pixels. It then sep-
arates the stream of data, (8-bit or 10-bit) into 3 (RGB) data (8-bit x 3)
and adds the color matrix to adjust and balance each of the R,G, and B
channels (white balance or color balance).
The image quality depends on the camera’s own pixel data (including
pixel data independency from neighboring pixels, noise and color filter),
and interpolation of the software algorithm such as 3 x 3 interpolation, 2
x 2 interpolation, color matrix, white balance capability, and so on.
All AccuPiXEL color cameras are carefully designed for maximum color
performance. JAI, Inc. strongly suggests that you use digital output for the best performance.
Some software is used on board (FPGA or DSP) to perform the interpolation. Other software simply
uses the host computer’s memory and CPU. The process speed may vary depending on the architec-
ture and speed of the computer.
