The correction data 1-n stored in the memory 66 are selected optionally by an external switch 67. The correction data read out of the memory 62 is added 65 to the correction data selected by the switch 67 and supplied to a color blurring correction coil 3 via a D/A converter 63. Thus the color blurring correction data can be set in accordance with an optional area with a simple external operation.
