ABSTRACT:
An electro-optical imaging array having pixels arranged in rows and columns electronically compensates for image motion in the plane of the array regardless of whether the motion vector is in the row direction, the column direction, or in a diagonal direction, i.e., in some vector combination of row and column directions. In an aerial reconnaissance application, the image motion may be due to rotation of the aircraft about roll, pitch and/or yaw angles in addition to forward velocity of the aircraft. The image motion compensation is achieved with no moving parts and does not require a stabilized platform.
A camera control computer determines the magnitude and direction of the image motion from inertial navigation system inputs, including velocity, flight, and aircraft rotation information, and calculates pixel information transfer rates in the row and column directions. The pixel information transfer rates are supplied to a counter and clock driver circuit for the array. The pixel information in the array is transferred in the row and column direction in a step-wise fashion in the row and column directions at a rate and direction substantially matching the image motion. The array itself is provided with a gate and control line design to enable charge representing pixel information to be transferred in both the row and column directions.
