ABSTRACT:
A method for dynamically correcting offsets of various pickup characteristics of a deflection system, a picture system and a mechanical system of a color television camera system in the course of an actual operation of the camera, so that the camera is maintained substantially under optimal picture shooting conditions. Selected components of the camera optical system, such as the pickup lens (optical systems), pickup devices and the like, are controlled by using as control parameters the iris value, zoom ratio, focal length and the like of the pickup lens, and image pickup conditions such as lighting conditions, surrounding temperature and time-dependent variation characteristics, and calculating exemplary correction values for correcting distortion of a pick-up image caused by the deflection system, picture system and mechanical systems. Based on the correction values, functional information which serve as references for correction signals adapted to correct offsets of the individual pickup characteristics are respectively calculated and stored. Upon an operation of the camera, information such as image pickup conditions and dynamic characteristics of the pickup lens are detected. Optimal correction signals are then calculated on the basis of the thus-detected information in accordance with the stored functional information of the corresponding correction signals. The optimal correction signals are thereafter fed to the corresponding optical system components to conduct dynamic (real time) correction on the images.
