摘要

Method for the automatic setup of 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 being present on a test chart in front of the camera and an internal test pattern being present in the camera in the optical path between a camera lens system and a camera pick-up arrangement. During the setup with the internal test pattern which is obtained by means of a light source, 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 belongs as a correction information to the lens system and is stored in a memory associated with the lens system. A setup to be effected thereafter by a camera operator and which is part of the preparation for scene recording can now be effected, without external test chart pattern, with the internal test pattern, the camera memory and the lens memory together producing the corrections for an optimum setup.
