Abstract:
1. A method for data transmission from an image array comprising the steps of: providing an X by Y array of detector elements; identifying a predetermined feature; examining the array elements for presence of the predetermined feature; defining a pixel set within a fovea associated with one or more elements of the array in which the predetermined feature is present; agglomerating elements outside of the fovea to create super-pixels; reading a data value from each of the foveal pixels and super-pixels in the array; and, analyzing the data values for temporal data content; providing a plurality of additional arrays comprising 12 arrays spaced circumferentially at substantially equal angles around the X by Y array; detecting the motion of a focused element of background image from one pixel to another pixel separated by a predefined distance in a circumferential array; calculating velocity based on the motion detection; spatially integrating calculated velocities for adjacent elements of the circumferential array; providing the integrated signal for modifying the foveal pixel set definition; and, modifying the definition of the foveal pixel set in response to the measured responses of the circumferential arrays.
