3.11.6 Interpolation Software
Major framegrabber manufacturers with digital capability (Camera Link, RS-644) provide color
interpolation software. Some independent image process software suppliers provide software as well.
The following table lists a few examples.
3.11.7 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 by filling the
missing color pixels with neighboring pixels. It then separates the single
stream of data (8-bit or 10-bit) into three (RGB) data streams (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, etc.
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 architecture
and speed of the computer.
