Abstract
PURPOSE:To always display a legible picture by automatically deciding the display color of an overlaied and displayed character or a graphic according to the picture element value of the picture of a background. CONSTITUTION:An overlay picture element value deciding circuit 2 calculates the average density value of a specific area and decides an overlay picture element value having a large density difference to the density value. According to this decided value, a binary/multi-valued converting circuit 4 converts the binarization information of the overlaid and displayed character or graphic into multi-valued information. Thereby, the character or the graphic is overlaied and displayed on a display means 6 with the color having the largest density difference to the display color of the background picture.
