型カラーテレビジョン受像機。A phosphor comprising, on the inner surface of a face plate of a picture tube, striped three primary color phosphors arranged repeatedly and striped index phosphors having a correlation with the three primary color phosphors and arranged repeatedly. An index in which an index optical signal is generated from each index phosphor by sweeping an electron beam emitted from a single electron gun to the phosphor layer, and the index optical signal is converted into an electric signal. The signal is pulsed to form an index pulse signal for controlling the electron beam irradiation position, and a luminance signal is added to a writing color signal which is a mixture of the index pulse signal and a color signal, and a luminance signal is added to the picture tube for beam scanning. A beam index type color television receiver that outputs a video signal includes a detection unit that detects a sudden change in image brightness from the brightness signal, and a detection unit that detects the color signal or the written color signal at the sudden change based on the output of the detection unit. A beam index type color television receiver comprising a level control section for lowering the level.
