LYNX Manual RA02
2.1.3
Center Columns Output (IPX-VGA210-L only)
The ‘center columns’ output mode is only available in the IPX-VGA210-L.
In this mode the image field has only 228 horizontal pixels located in the
center of the imager – Figure 2.3. When operating in a single output mode,
all 228 pixels are shifted out of the HCCD register towards the left video
amplifier – Video L (Figure 2.4). The resulting image has a normal
orientation and a frame rate of 289 frames per second.
When operating in a dual output mode, the image is split in two equal parts,
each having 114 pixels and full vertical lines. The frame rate in this mode is
546 frames per second. The first (left) half of the pixels is shifted out of the
HCCD register towards the left video amplifier – Video L, while the second
(right) half of the pixels is shifted towards the right video amplifier – Video
R (Figure 2.5). In the horizontal direction the first half of the image appears
normal and the second half is left/right mirrored. The camera reconstructs
the image by flipping the mirrored portion and rearranging the pixels.
