A support frame is coupled to a counterweight frame to form a mechanical oscillator in which oscillations of adjustable amplitudes are induced to produce parallax, oscillatory scanning motion of a camera rotatable mounted by the support frame. A spring assembly, acting on the support and counterweight frames, establishes an effective spring constant to tune the resonator to a particular resonate frequency. Rotatable motion of the camera relative to the support frame consistently directs the optical axis of the camera to a signal convergence point in the scene being photographed. Separate motors are selectively energized by a control system to regulate the amplitudes of resonator oscillation to a desired disparity setting, to tune the resonator to a desired resonant frequency setting, and to direct the camera to a desired convergence point setting.
