    • An electro-optical imaging array provides compensation for image motion due to variations in scene terrain electronically and with no moving parts. Pixel information representing scene information is transferred through the array in column groups. Each column group has its own charge transfer rate U. Successive images of the scene are generated by the imaging array, and the images are correlated by electronic signal processing circuitry to determine the image displacement of a fixed point in the scene between successive images. The image displacement is used to calculate a residual image velocity U.sub..delta. in each column group. As successive images of the scene are generated, the charge transfer rates U for each column group are updated, whereby U=U.sub.0 -U.sub..delta., where U.sub.0 is the charge transfer rate for the previous exposure, and U.sub..delta. is the residual image velocity in each column group.
    • 电光成像阵列由于电子场景地形的变化以及没有运动部件而对图像运动提供补偿。 表示场景信息的像素信息通过数组以列组形式传送。 每个列组具有其自己的电荷传送速率U.场景的连续图像由成像阵列产生,并且图像通过电子信号处理电路相关联,以确定连续图像之间的场景中的固定点的图像位移。 图像位移用于计算每个列组中的残留图像速度U delta。 随着场景的连续图像的生成,每列组的电荷转移率U被更新,由此U = U0-U delta,其中U0是先前曝光的电荷转移速率,U delta是残留图像速度 每列组。

    • 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.
    • 具有排列成行和列的像素的电光学成像阵列电子地补偿阵列的平面中的图像运动,而不管运动矢量是在行方向,列方向还是在对角线方向上,即在某些方面 行和列方向的向量组合。 在空中侦察应用中,图像运动可能是由于除了飞行器的向前速度之外,飞机关于滚动,俯仰和/或偏航角度的旋转。 图像运动补偿无需移动部件即可实现,不需要稳定的平台。 相机控制计算机确定惯性导航系统输入的图像运动的大小和方向,包括速度,飞行和飞行器旋转信息,并计算行和列方向上的像素信息传输速率。 像素信息传送速率被提供给阵列的计数器和时钟驱动器电路。 阵列中的像素信息在行和列方向上以逐行方式以基本上与图像运动匹配的速率和方向在行和列方向上传送。 阵列本身设置有栅极和控制线设计,以使得能够在行和列方向上传送代表像素信息的电荷。

    • An aerial reconnaissance system generates imagery of a scene that meets resolution or field of view objectives automatically and autonomously. In one embodiment, a passive method of automatically calculating range to the target from a sequence of airborne reconnaissance camera images is used. Range information is use for controlling the adjustment of a zoom lens to yield frame-to-frame target imagery that has a desired, e.g., constant, ground resolution or field of view at the center of the image despite rapid and significant aircraft altitude and attitude changes. Image to image digital correlation is used to determine the displacement of the target at the focal plane. Camera frame rate and aircraft INS/GPS information is used to accurately determine the frame to frame distance (baseline). The calculated range to target is then used to drive a zoom lens servo mechanism to the proper focal length to yield the desired resolution or field of view for the next image. The method may be performed based on parameters other than range, such as aircraft height and stand off distance.
