<p>An apparatus and a method are provided for smoothing out high frequency information in an interlaced computer generated display. A computer generated RGB signal is converted into a YUV signal, which is separated into its Y, U, and V components. The Y component is convolved by averaging a current scan line with a line above and a line below the current scan line so that black lines are lightened and white lines are darkened, thus avoiding flicker. Since convolution is only performed on the Y part of the YUV signal, only two line buffers, each having a width equal to the number of bits in the Y component only, are required.</p> |
