Method and apparatus for an on-chip variable acuity imager array incorporating roll, pitch and yaw angle rates measurement
First Claim
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.

Abstract
A variable acuity imager incorporates an array of detection elements for light energy, in the visible, infrared, ultraviolet, or light energy in another region of the electromagnetic spectrum with a means to change the spatial configuration of the array to include “superpixels” by combining energy detected by adjacent elements, thus permitting any number of high-resolution “foveal” regions to be placed within the confines of the focal plane array and moved around at the frame rate of the imaging device. Detectors to measure the pitch, yaw and roll angle rates of background imagery using velocity-sensing circuitry are employed for variation of the foveal regions to accommodate motion of the array.

10. An integrated on-chip variable acuity imager array comprising:
-
a plurality of image elements arranged in an X by Y array, each of the elements including a detector and a charge integration capacitor;
means for connecting the charge integration capacitor of each element to the charge integration capacitor of a left adjacent element responsive to a first control signal;
means for connecting the charge integration capacitor of each element to the charge integration capacitor of an upper adjacent element responsive to a second control signal;
means for selectively generating the first control signal for each element in a dynamically defined super-pixel;
means for selectively generating the second control signal for each element in the dynamically defined super-pixel;
means for dynamically defining at least one super-pixel;
means for reading the charge integration capacitor of each element not receiving a control signal and for reading the charge integration capacitor of a master element in each super-pixel, the master element being the leftmost and uppermost element in the super pixel. - View Dependent Claims (11, 12, 13, 14)
