Internally, images flow from an input stage, through a processing stage and then to an output stage, illustrated in Figure 4. In general, there are two input images and two output images, but as shown in Figures 5 and 6 some instances of the system may deal with only one of the two images, or may treat the two images as a single combined stereo image. The input and output stages may be any general, arbitrary way of inputting or outputting an image (stereo or not), but would most commonly be those listed in Section 3.1.
Figures 5 and 6 show two ways in which several Stereocam instances, running on different hosts, may be used to record and display stereo images and stereo movies. Figure 5 is envisaged as the most common setup for the system, whereas Figure 6 is the setup described in Section 2.
