ABSTRACT:
A digital convergence correcting device effecting convergence correction by using convergence correcting data stored in a memory which includes an address fixing device which, in the case where convergence correcting data are insufficient, reads out in succession the correcting data corresponding to the last horizontal scanning line for the portion lacking in the data so that the correcting data are used repeatedly, and which, in the case where convergence correcting data are excessive, only necessary convergence correcting data are used.
