ABSTRACT:
An image distortion correcting apparatus for a television camera. In addition to an analogue correcting waveform, four corner independent distortion correcting waveforms are employed for rough adjustment together with a digital distortion correcting signal serving for fine adjustment. These waveforms are combined to be utilized for correcting image distortion from which the television camera suffers. A high-accuracy correction of image distortion can be accomplished with a circuit configuration of a small scale.
