Abstract

PURPOSE:To make automatic adjustment of a television receiver so that the focus can be optimized at all time, by controlling the level of DC voltage of focus with a phase comparison output detecting the state of focus. CONSTITUTION:A DC focus electrode FV superimposed with an AC signal with a certain period is given, and an amplitude detection signal when the electron beam of an index signal is a constant beam amount is compared with the superimposed AC signal for the phase, and the level of the DC voltage FV is controlled with the phase compared output and the focus is automatically adjusted so that the focus can be optimum.
