Normal Mode – Quad Output
When operating in a quad output mode, the image is split into four equal quadrants,
each quadrant consisting of half of the horizontal pixels and half the vertical lines. In
the first quadrant (bottom left), half of the pixels are shifted out of the HCCD
register towards the bottom left video amplifier – VOUTa, while the remaining
quadrants are shifted towards their respective video amplifiers – VOUTb,VOUTc,
and VOUTd (Figure 2.3). In the horizontal direction the left side quadrants appear
normal and the right side quadrants are left/right mirrored. In the vertical direction
the top two quadrants appear normal and the bottom two quadrants are vertically
mirrored. The camera reconstructs the image by flipping the mirrored quadrants and
rearranging the pixels. Quad output is the only mode of operation for the quad
cameras – refer to the Configuration Memory section. The image resolutions for the
quad cameras are shown in Table 2.1, and a frame rates – in Table 2.3.
