Rotation of the camera about its optic centre does not change the optic array and allows the visual direction of objects to be represented in a number of ways. Figure from
[1] Pure rotation of the eye/camera about its optic centre causes no change in the optic array (define). There are various sensible ways to represent the information in the optic array, including a mosaic (reference). Saccades allow the eye to sample different parts of the optic array at a high resolution. Moving between these can be described in terms of the sensory-motor mappings discussed elsewhere (e.g.
here and
here). Looking at object
A with object
B currently imaged on peripheral retina and having the motivation to fixate
B leads to a saccade to
B. A series of such sensory+motivational contexts would allow an observer/camera to alter fixation from any object to any other and hence form a representation of 'where' each object is in the optic array.
