Abstract: According to one embodiment, a moving object image tracking apparatus includes two drivers, a camera sensor, a tracking error detector, angle sensors, angular velocity sensors, a first calculator, a second calculator, a corrected tracking error detector, a generator, and a controller. The tracking error detector detects tracking errors as deviation amounts of a moving object from a visual field center from the image data as tracking error detection values. The corrected tracking error detector calculates corrected tracking errors for each period shorter than a sampling period, tracking error detection values being constant, from a velocity vector and a relationship between a visual axis vector and a position vector. The generator generates angular velocity command values required to drive the drivers to track the moving object using the corrected tracking errors. The controller controls the drivers so that differences between the angular velocity command values and angular velocities become zero.

Abstract: An apparatus includes a first-computation unit computing first-angular-velocity-instruction values for driving first-and-second-rotation units to track a moving object, using a detected tracking error and a detected angles, when the moving object exists in a first range separate from a zenith by at least a preset distance, a second-computation unit computing second-angular-velocity-instruction values for driving the first-and-second-rotation units to track the moving object and avoid a zenith-singular point, using the detected angles, the detected tracking error and an estimated traveling direction, and a control unit controlling the first-and-second-rotation units to eliminate differences between the first-angular-velocity-instruction values and the angular velocities when the moving object exists in the first range, and controlling the first-and-second-rotation units to eliminate differences between the second-angular-velocity instruction values and the angular velocities when the moving object exists in a
