ABSTRACT:
A television receiver includes a caption data display control circuit for controlling display of caption data contained an image of input standard video signal on a display screen for a wide aspect ratio in a full screen display mode for displaying the image on the entire display screen. In the caption data display control circuit, a luminance signal contained in the input standard video signal is converted into a first set of pixel values corresponding to all of the pixels consisting of the image. The second set of pixel values representing the caption data from values of pixels is then automatically detected by a detection circuit thereof from a first predetermined image region within the image. The detected second set of pixel values is converted into a caption signal denoting the caption data which is combined with the luminance signal in order to be displayed on a visible area of the display screen.
