Abstract:
1. A display control apparatus to display image data expressed under a plurality of different kinds of color spaces, the apparatus comprising: a discriminating section which discriminates a kind of a color space of image data based on color space information of the image data to be displayed; a memory which stores a display pattern comprised of on-screen display (OSD) data and a plurality of color palettes relating to the display pattern; a palette selecting section which selects a desired color palette from the plurality of color palettes relating to the display pattern based on the kind of the color space discriminated by the discriminating section; an OSD data generating section which generates display OSD data by converting the OSD data of the display pattern using the color palette selected by the palette selecting section; a mixing section which mixes the display OSD data, generated by the OSD data generating section, with the image data, thereby generating display image data; a gain switching section which switches gains to amplify the display image data mixed by the mixing section, in accordance with the kind of the color space discriminated by the discriminating section; and an amplifying section which amplifies the display image data based on the switched gain, wherein the amplifying section further comprises a separating section which separates the display image data into a luminance signal and a color difference signal, and amplifies only the color difference signal separated by the separating section based on the switched gain.
