ABSTRACT:
A system for correcting for positional deviations in a hand-held video camera caused by small movements or shaping of the user's hands includes an afocal optical system constituted by a positive meniscus lens and a negative meniscus lens. The positional deviations of the camera caused by minute tremors or shaking of the user's hands are detected by a pitch sensor and a roll sensor and a micro-computer is responsive to the detected amount of the positional deviations to drive the positive meniscus lens and the negative meniscus lens in vertical and horizontal directions with respect to the optical axis, thereby controlling the position of the image pickup light being radiated onto a CCD image sensor of the video camera.
