ABSTRACT:
There is provided with an image display method including: creating a histogram indicating frequencies of pixels included in level-ranges associated with representative gray-scale levels; calculating differences between first brightnesses each predetermined for the each representative gray-scale level and second brightnesses each preliminarily obtained for the each representative gray-scale level displayed on an image display with each of a plurality of light-source levels of light-source luminance, accumulating, for each of the representative gray-scale levels, products of the differences by the frequency, selecting a selected light-source level having the smallest accumulated sum or the smaller accumulated sum than a threshold value; providing signals of one frame of an input video image to a light modulation device that displays an image by modulating a transmittance or a reflectance of light from a light source, and controlling so that the light source emits light in luminance corresponding to the selected light-source level.
