Claim:
1. An image display device comprising: an image acquisition unit configured to acquire a wide dynamic range image formed by performing dynamic range extension processing or a normal image without dynamic range extension processing; a transmissive type display panel configured to display the wide dynamic range image or the normal image acquired by the image acquisition unit; a backlight unit that is provided in a back face of the transmissive type display panel, the backlight unit configured to control luminance of backlight with respect to the transmissive type display panel for each of divided segments; a determination unit configured to determine whether an image acquired by the image acquisition unit is the wide dynamic range image or the normal image based on meta data read out from the image acquired by the image acquisition unit; and a control unit configured to control the backlight unit so that backlight luminance of a segment corresponding to a higher luminance portion suppressed by dynamic range extension processing in the wide dynamic range image becomes higher than backlight luminance of a segment corresponding to a lower brightness portion in the wide dynamic range image, only when the image acquired by the image acquisition unit is determined to be the wide dynamic range image by a determination result of the determination unit.
