Abstract
In an image display apparatus including a delta-array display device and pixel position transition means for repeatedly shifting the respective pixel positions of the display device to each of positions at four points, the pixel shifted positions at the four points are: a first pixel position serving as standard; a second pixel position shifted with respect to the first, standard pixel position horizontally approximately by ½ of horizontal pixel pitch; a third pixel position shifted horizontally approximately by ¾ or ¼ of horizontal pixel pitch and vertically approximately by ½ of vertical pixel pitch; and a fourth pixel position shifted horizontally approximately by ¼ or ¾ of horizontal pixel pitch and vertically approximately by ½ of vertical pixel pitch. The image display apparatus is thereby provided as having an improved, doubled resolution in both vertical and horizontal directions by applying the 4-point pixel shift system to the delta-array display device.
