Abstract
Method for automatically setting up a television camera by means of a microcomputer. The setup is effected in two separate steps, a test pattern being used in each step. An external test pattern is present on a test chart in front of the camera and an internal test pattern is present in the camera in the optical path between a camera lens system and a camera pickup arrangement. During the setup with the internal test pattern, the lens system is optically blocked and correction information is stored in a memory. During or after the setup with the external test pattern, the correction information associated with the internal test pattern is subtracted from the correction information associated with the external test pattern. The resulting correction difference information is lens correction information and is stored in a memory associated with the lens system. Now, the camera operator can prepare for scene recording without an external The internal test pattern in the camera memory and the lens memory together produce the correction for an optimum setup.
