PURPOSE:To execute the registration adjustment of a multi-tube color television camera with high accuracy by controlling a deflection system of each video tube based on a registration correction data obtained by a data processing means. CONSTITUTION:Correction data Dn of 8 bits is supplied to a data selector circuit 71 through a data bus. Said circuit 71 weights selectively each correction data ahead of two horizontal lines by 1/2 with respect to the data Dn, and said correction data is selectively controlled in such a way that all bits are transmitted due to control signals supplied to a control input terminal 75, or the 1/2 weighting is conducted by rotation. When the correction data weighted selectively by the circuit 71 is supplied to an adder 73 through a data latch circuit 72, registration correction data Dn' can be obtained as addition output data. After the data Dn' is D/A-converted, it is supplied to a deflection control circuit.
