Normal
Mode – Dual Output
When operating in a dual output mode, the image is split in two equal parts,
each side consisting of half of the horizontal pixels and the full vertical lines.
The first (left) half of the pixels are shifted out of the HCCD register towards
the left video amplifier – Video L, while the second (right) half of the pixels
are shifted towards the right video amplifier – Video R (Figure 2.1). 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. Dual output is the default factory
mode of operation – refer to the Configuration Memory section. The image
resolutions, and frame rates for different cameras are shown in Table 1.6
Figure 2.1– Dual output mode of operation.

FRAME TIME CONTROL

Frame Time (Long Integration) Control
The camera speed (frame rate) depends on the CCD “read-out” time – the time
necessary to read all the pixels out of the CCD imager. The frame rate can be
calculated using the following Formula 1.1:
