Abstract
A transforming device for transforming computer graphics signals to television signals is provided. The transforming device includes a scaled-down line generating unit that receives the computer vertical line and generates the scaled-down vertical line, a controller that receives the scaled-down vertical line, and a scaled-down buffer that stores the scaled-down vertical line or the value of the scaled-down vertical line performed by the weighted-averages method. The content of the scaled-down buffer is transmitted to a weighted-averages operation unit, and then it is performed by the weighted-averages method with the next scaled-down vertical line. When a TV line is generated, it is the output of the transforming device. The present invention has the advantage of reducing the needed buffers in the transforming process and thereby reducing the cost.
