Abstract:
1. A liquid crystal display device comprising: an emphasis conversion section configured to perform an emphasis conversion process on image data of a current frame, based on an emphasis conversion parameter corresponding to a combination of image data of the current frame and image data of a frame immediately preceding the current frame or image data corresponding to an image assumed to be actually displayed on a liquid crystal display panel in the frame immediately preceding the current frame; driving sections configured to cause the liquid crystal display panel to display an image corresponding to the image data on which the emphasis conversion process has been performed by the emphasis conversion section; a temperature detection section configured to detect an in-device temperature of the liquid crystal display device; a light intensity detection section configured to detect a light intensity of incident external light into the liquid crystal display panel; a panel temperature calculation section configured to calculate a temperature of the liquid crystal display panel, based on the in-device temperature detected by the temperature detection section and the light intensity of the incident external light detected by the light intensity detection section; and a control section configured to change the emphasis conversion parameter to be used in the emphasis conversion process in accordance with the temperature of the liquid crystal panel calculated by the panel temperature calculation section.
