Color television camera device

Abstract

Abstract PURPOSE:To perform the automatic adjustment accurately and easily in lens replacement also, by comparing corresponding lens correction data, reference data, and adjustment data in an operation processing circuit in accordance with the replacement of a photographic lens. CONSTITUTION:A correction signal generating circuit 13 consists of a primary storage circuit and a digital/analog (D/A) converting circuit, and correction data from an operation processing circuit 11 is stored temporarily in this circuit 13, and data is converted to an analog signal by this circuit 13. Signals concerning registration such as centering, the picture size, or the like out of analog signals are supplied to a deflecting circuit 14, and deflecting operations of image pickup tubes 3 and 4 of R and B are corrected, and signals concerning level such as pedestal correction, gain correction, gamma correction, or the like are supplied to a signal processing circuit 6. Thus, the device is so constituted that all corrections are performed by this correction signal.
