Abstract
An image recording method for an image recording medium is used in an image display apparatus that changes an image on a light valve and changes quantity of light which is incident on the light valve via a light control element according to an input image signal. The image recording method includes accommodating a range of brightness information which an object to be imaged indicates, in an entire range of brightness information which an image recording apparatus can record in the image recording medium; and recording a light-control control signal for controlling the light control element when an image signal is recorded on the image recording medium. The light control element is generated on the basis of the range of the brightness information uniformly expanded, in synchronization with the image signal.
