1. An image display system, comprising: a dividing apparatus configured to divide a source image into N divisional images such that the images of neighboring regions may not overlap with each other and signal the N divisional images, N being a natural number equal to or greater than two; N transmission lines configured to individually transmit the N divisional images; N dummy pixel insertion sections configured to produce dummy pixels individually based on the corresponding divisional images and insert the produced dummy pixels individually to the outer side of the corresponding divisional images to produce expanded images; each N image processing section configured to apply a spatial signal process individually to the corresponding expanded images; N divisional image cutting out sections configured to remove image components corresponding to the dummy pixels individually from the corresponding spatially processed images to cut out divisional images of an image size equal to the size of the divisional images signaled from said dividing apparatus; and an image synthesis section configured to patch the cut out N divisional images to produce a re-synthesized image of an image size equal to the image size of the source image.
