A display device includes: a display panel; and a frequency controller which receives an image data signal and an input frequency information and outputs the image data signal and a timing control signal. The frequency controller includes: an image processor which receives the image data signal; a frame memory which stores the image data signal; an output frequency determining unit which receives the input frequency information and determines an output frequency based on a variation amount of the input frequency; and an image output unit which receives the image data signal from the image processor, receives an output frequency information from the output frequency determining unit, and outputs the image data signal and the timing control signal. When an input frequency varies, the output frequency determining unit determines the output frequency based on the following equations:

[00001]$K=.Math.\frac{\mathrm{FREQ}-\mathrm{P\_FREQ}}{\mathrm{M\_FREQ}}.Math.\mathrm{SLOPE}+\mathrm{OFFSET},\mathrm{and}$${\mathrm{FREQ}}^{}=\mathrm{FREQ}K+\mathrm{P\_FREQ}\left(1-K\right).$

An image-processing device is configured to detect a motion region within an input image; generate an intermediate image from an N-th frame and an (N+1)-th frame; perform processing of reducing a high-frequency component of spatial frequency on the intermediate image; and output an image of which a frame rate is increased by insertion of the intermediate image having undergone the processing between the N-th frame and the (N+1)-th frame. When a target position at which a pixel value of the intermediate image is to be calculated lies within the motion region, a pixel value of the intermediate image at the target position is calculated using a pixel value of the N-th frame and a pixel value of the (N+1)-th frame at a position in the vicinity of the target position and outside the motion region.
