Abstract:
A device for generating pixel luminance signals corresponding to text to be displayed comprising:a) means for selectively generating a normal mode signal for selected first text and a high intensity mode signal for highlighting selected second text concurrently displayed with said first text;b) means for receiving an intensity signal specifying a first mode or a second mode; andc) means, coupled to the means for receiving, for generating background pixel luminance signals of a first luminance level and, in the first mode, for decreasing contrast while increasing overall luminance, relative to said second mode, of said first text by generating foreground pixel luminance signals of a second luminance level with less luminance than the first luminance level and, in the second mode, for increasing contrast while decreasing overall luminance of said second text to be highlighted by generating foreground pixel luminance signals of a third luminance level with less luminance than the second luminance level, whereby said first text in the first mode and said second text in the second mode are displayed concurrently.
