Abstract

PURPOSE:To obtain an excellent horizontal linearity correcting signal with no error, by further correcting a corrected signal written in a horizontal linearity correction memory. CONSTITUTION:A fixed beam current is flowed to beam index type color picture tube 1 for a beam scan and the 1st horizontal linearity corrected signal obtained at this time is written in memory 14 being A/D-converted 23. Next, this corrected signal read out and, after D/A conversion 15, is supplied to horizontal linearity correcting method 17. At the same time, a fixed beam current is flowed to picture tube 1 for a beam scan, thereby generating the 2nd corrected signal. The 2nd corrected signal and the 1st corrected signal read out of memory 14 are added 25 and the sum is A/D-converted 23 before being written in memory 14. Thus, the corrected is signal of memory 14 is the further-corrected 1st corrected signal, so that the excellent corrected signal with no error can be obtained.
