3.11 Color Creation in the A102kc
The CCD sensor used in the
A102
kc
is equipped with an additive color separation filter known as
a Bayer filter. With the Bayer filter, each individual pixel is covered by a micro-lens which allows
light of only one color to strike the pixel. The pattern of the Bayer filter used in the
A102
kc
is shown
in Figure 3-20. As the figure illustrates, within each block of four pixels, one pixel sees only red
light, one sees only blue light, and two pixels see only green light. (This combination mimics the
human eye’s sensitivity to color.)

A102
fc
When an
A102
kc
is operating in single 8 bit, 10 bit, or 12 bit output mode, a single value is
transmitted out of the camera for each pixel in a captured image. If you want to get full RGB color
information for a given pixel in the iamge, you must perform a color interpolation using the
information from the surrounding pixels. Some frame grabbers are capable of performing the color
interpolation and many algorithms are available for performing the interpolation in your host PC.

When you are using an
A102
kc
color camera and the camera is set for a single pixel
output mode, the order of the pixel colors output from the camera is determined by
the alignment of the Bayer filter to the sensor as shown in Figure 3-20. If you use the
AOI feature (see Section
) and you change the position of the AOI, be aware that
you may change the order of the pixel colors output from the camera.
