Patent ID: 8451209

Claim:
A liquid crystal display device, comprising: a section that detects a type of content of an image to be displayed on a liquid crystal display panel, based on electronic program information other than the image signal to be displayed and on additional information as to motion blur, the detected type of content being based on a classification defined in the electronic program information, where motion blur is blur recorded in the image signal due to at least one of relative subject motion and image shooting conditions during capture of the image; a section that stores a plurality of predetermined illumination durations which respectively correspond to possible types of content of an image; an electrode driver supplying a driving signal to at least one picture element; and a section that variably controls the illumination duration of a backlight within one frame period and the duration in which a black display signal is supplied from the electrode driver to at least one picture element of a liquid crystal display panel based on the detected type of content of the image according to the stored illumination duration which corresponds to the detected type of content of the image based on the classification defined in the electronic program information, wherein the image signal to be displayed is written into the liquid crystal display panel while the backlight is activated intermittently within the one frame period, the stored plurality of predetermined illumination durations are set in such a manner that: the larger an amount of motion blur entailed in the image with respect to its detected type of content, the shorter the corresponding illumination duration within the one frame period, and the smaller the amount of motion blur entailed in the image with respect to its detected type of content, the longer the corresponding illumination duration within the one frame period.
