A control apparatus for image blur correction is applied to an image blur correction device. The control apparatus comprises a microcomputer which forms a driving signal for driving the image blur correction device in accordance with a signal corresponding to an output of a vibration detection sensor, an offset signal removing circuit which removes an offset signal from the output of the vibration detection sensor before the signal corresponding to the output of the vibration detection sensor is entered into the microcomputer and which supplies a signal resulting from the removal of the offset signal, as the signal used for the formation of the driving signal by the microcomputer, to the microcomputer, a removal offset value of the offset signal removing circuit being set variably, a removal offset value setting circuit which sets the removal offset value for the offset signal removing circuit and which thereafter makes the offset signal removing circuit carry out a removal operation based on the removal offset value thus set and an instruction device (the functional part of the microcomputer, etc.) which gives an instruction for carrying out a setting operation of the removal offset value, to the removal offset value setting circuit, the instruction device giving the instruction for carrying out the setting operation of the removal offset value even in a state in which the offset signal removing circuit has already executed the offset signal removal operation and is entering the signal resulting from the removal of the offset signal into the microcomputer.
