Patent ID: 7639228

Claim:
A liquid crystal display device that obtains with a given cycle a video signal that changes on a basis of time and displays video based on the obtained video signal, the liquid crystal display device comprising: a displaying unit including a liquid crystal panel; a storing unit configured to store the video signal; a temperature detecting unit configured to detect a temperature of the displaying unit; a determining unit configured to distinguish, with respect to the video signal, between (i) a moving image portion indicating a moving object that moves not less than a given movement amount and (ii) a still image portion other than the moving image portion; a warning unit configured, in case that the determining unit detects the moving image portion indicating the moving object that moves not less than the given movement amount when the temperature detecting unit detects a temperature less than a predetermined temperature, and to notify using a message indicating that the moving image portion is processed based on the stored video signal and displayed in the liquid crystal panel of the displaying unit; and a generating unit configured, in case that the determining unit detects the moving image portion indicating the moving object that moves not less than the given movement amount when the temperature detecting unit detects the temperature less than the predetermined temperature to generate, with respect to the moving image portion, (i) movement display data that indicates a movement position of the moving image portion based on a new video signal, which is obtained after a previous video signal; and (ii) video display data indicating the moving image portion to be displayed by the displaying unit, the video display data being generated by moving, according to the generated movement display data indicating the movement position, the moving image portion based on the previous video signal, and the displaying unit being further configured to display the moving image portion by using the video display data, which is generated based on the previous video signal by the generating unit, without using the new image signal.
