3.11.6 Interpolation Software

Major frame grabber 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 PULNiX

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.
