ABSTRACT:
Image display method and apparatus are capable of displaying an input image signal in an optical condition on a display screen according to the brightness of the screen image. The image display apparatus for performing a specified process on an input image signal and displaying an image by the image signal on a display unit comprises a controller for adjusting a signal level detecting circuit for detecting brightness levels of an image by the input image signal by controlling the sharpness of an image by the image signal according to a detected signal level in such a way that as the detected signal level rises, the sharpness increases.
