An apparatus for minimizing vibration of images in video cameras due to vibration of the operator's hands includes a motion detector, an electric field generator which receives information from the motion detector and generate voltages related to the horizontal and vertical motions, and a hand vibration corrector which uses the voltages from the electric field generator to control the refractive index of a medium through which the incoming video images are passing, to thereby adjust the position of the incoming images. A CCD converts the optical signals of the hand vibration correcting means into electrical signals. The refractive index of the crystal having the electro-optical effect is controlled by electrical signals and the optical source of the input images is optically corrected. Consequently, a high speed response and high precision controlled resolution are provided. Further, the apparatus has a simple structure, and therefore, it can greatly contribute to the camera image stabilization.
