Falcon XDR and HG Series Camera User's Manual DALSA
Camera Hardware Interface 27
The color camera model has a Bayer filter applied to the CMOS sensor to allow for color separation.
Each individual pixel is covered by either a red, green, or blue filter as shown in the figure below. The
camera outputs raw color data--no color interpolation is performed. Full RGB images can be obtained by
performing color interpolation on the frame grabber or host PC. The diagram below illustrates the case for
the Falcon 1.4M100 camera. The Falcon 1M120 and Falcon VGA300 are identical to the Falcon
1.4M100, where Green is the filter on top of row 1, column 1, and the rest of the pixels are defined by the
nature of the Bayer pattern.

2.3.1 Camera Readout and Coordinates
The camera readout begins with pixel 1 and reads out successive pixels from left to right until the entire
row is completed. This process is repeated with each successive row in the frame. Pixel coordinates are
expressed as column and rows, where the first pixel’s coordinates are 1, 1 and the last pixel’s
coordinates are 1400, 1024.
