Abstract
PURPOSE:To clearly display a character by superimposing the character on a picture and making the picture of the circumference of the character low brightness. CONSTITUTION:The level of the luminance signal of a video signal to be inputted is set to a prescribed value lower than an input level by a luminance signal level setting means 16 to the prescribed output timing of the character outputted from a character generating means 30 to lower the brightness of the picture of the circumference of the character so as to understand a contour. Thereby, even when many or large character is considerably superimposed on the picture, the picture of the circumference of the character is not completely omitted but the character is clearly displayed.
