Abstract
It is to make the sizes of “blur” in a moving image uniform in a liquid crystal display unit of a hold-type display device by suppressing deformations and discolorations of the moving image caused due to ununiformity in the response speed of the liquid crystal panel. The display device includes a frame memory and a correction frame signal generating device as correction frame signal generating devices which compare pixel gradation levels defined by one frame and a frame one before among the image signals inputted from the outside, and generate an image signal of a correction frame for reducing a delay in the response time of the pixel. At the same time, the liquid crystal display device displays the correction frame on the liquid crystal panel between that one frame and the frame one before.
Claims25
A liquid crystal display device for displaying image signals on a liquid crystal panel with a plurality of pixels by switching a screen for each frame, the device comprising:
- a frame frequency converting part for multiplying a frame frequency of an inputted image signal;
- and
- a correction frame signal generating device for generating an image signal of a correction frame based on gradation changes in the image signals of previous and following inputted frames, and displaying the correction frame between corresponding previous and following frames to adjust a blur position in a displayed image.
A liquid crystal display means for displaying image signals on a liquid crystal panel with a plurality of pixels by switching a screen for each frame, the means comprising:
- a frame frequency converting means for multiplying a frame frequency of an inputted image signal;
- and
- a correction frame signal generating means for generating an image signal of a correction frame based on gradation changes in the image signals of previous and following inputted frames, and displaying the correction frame between corresponding previous and following frames to adjust a blur position in a displayed image.
An image displaying method for displaying an image on a liquid crystal panel that includes a plurality of pixels, the method comprising:
- converting a frame frequency of an input image signal by multiplying the frame frequency;
- generating an image signal of a correction frame based on gradation changes in the image signals of previous and following inputted frames;
- and
- displaying an image on the liquid crystal panel by adjusting a blur position in a moving picture through inserting the correction frame between corresponding previous and following frames.
An image displaying program for allowing a computer to execute:
- a frame frequency converting function which multiplies a frame frequency of an inputted image signal;
- a correction frame image signal generating function which generates an image signal of a correction frame based on gradation changes in image signals of previous and following inputted frames;
- and
- a displaying function which displays an image on a liquid crystal panel by adjusting a blur position in a moving picture through inserting the correction frame between corresponding previous and following frames.
