Abstract

a teletext processing unit for processing a text broadcasting data; a control unit(4) for generating color control signals(color, contrast, tint, and brightness); a color processing unit(7) for processing RGB colors from the teletext processing unit(6) and an image processing unit according to the color control signal(S1-S4). A brightness varying unit(8) is added to the apparatus for varying a brightness control signal(S4) from the control unit according to a surrounding luminance when a teletext broadcasting is performed by a teletext processing unit(6).
