Image display apparatus with improved image portion

An image display apparatus, comprising:

• an image display plane comprising a plurality of pixels arranged with a pixel pitch;
• image display control means for receiving an input image signal and, in accordance with said input image signal, displaying an image on a substantially whole area of the image display plane and a part of the image on a selected region of the image display plane by shifting image display positions of the image with respect to said image display plane in a given direction by an integer multiple or an inverse of an integer multiple of the pixel pitch of the image display plane;
• and
• image display plane shift means for effectively and selectively shifting, in synchronism with the operation of said image display control means, a display position of said part of said image with respect to said selected region of said image display plane, in a direction opposite to said given direction in which said image display position shifting is carried out,
• wherein said selected region in the image display plane is formed to have a plurality of areas which are separated from each other.
