    摘要: The present invention is concerned with image display apparatus capable of displaying the image of each of a television signal (TV signal) and an image signal (PC signal) from a personal computer. In addition, the present invention is to improve the performance of such apparatus, particularly to prevent the image from being deteriorated when the pixel number is converted, or changed to increase the pixel number of each of the TV signal and PC signal. In order to achieve this, the apparatus according to the invention has its pixel number conversion circuit provided with a plurality of conversion modes of different systems so that the pixel number conversion can be performed by properly switching the conversion modes in accordance with the type of the input image signal.
