Image data as transferred directly to system memory from a Dalsa CA-D4 two-
channel camera and 2b after hardware reordering into scan line order by a frame
grabber.
To alleviate this problem, many digital frame grabbers incorporate pixel swizzling
circuitry to dynamically rearrange the pixels into scan line order so that the
application can immediately begin the image-processing task.
Differeent cameras employ a number of different image-formatting schemes. The
most common are shown in Figure 4.
