Image recording method, image recording apparatus, image recording medium, image display method, and image display apparatus for reading and recording actual brightness

An image display apparatus which changes an image on a light valve according to an input image signal, and changes, by a light control element, quantity of light which is incident on the light valve, comprising:

• a unit that reads the input image signal and a light-control control signal for controlling said light control element from an image recording medium;
• a unit that creates a modulated image signal based on a combination of the input image signal and the light-control control signal read from the image recording medium;
• a unit that utilizes a dynamic range of the light valve fully when said input image signal is reproduced based on the modulated image signal;
• and
• a unit that controls a quantity of light of said light control element on the basis of said light-control control signal in synchronization with the input image signal from the modulated image signal,
• wherein the light-control control signal relates to an amount of ambient light incident on a camera at the time of taking a picture.
