Abstract
A display device includes: an image input unit configured to receive an image signal; a frame skip detector configured to detect a frame skip in the image signal; a frame skip compensation adjuster configured to determine information indicating whether to perform frame interpolation, interpolation input frame information, and an interpolation time, based on the frame skip detected by the frame skip detector; a frame interpolator configured to generate an interpolation frame, based on the information indicating whether to perform frame interpolation, the interpolation input frame information, and the interpolation time; and an image output unit configured to output an image signal including the interpolation frame corresponding to the interpolation time.

A display device comprising:
- an image input unit configured to receive an image signal;
- a frame skip detector configured to detect a frame skip in the image signal;
- a frame skip compensation adjuster configured to determine information indicating whether to perform frame interpolation, interpolation input frame information, and an interpolation time, based on the frame skip detected by the frame skip detector;
- a frame interpolator configured to generate an interpolation frame, based on the information indicating whether to perform frame interpolation, the interpolation input frame information, and the interpolation time;
- and
- an image output unit configured to output an image signal including the interpolation frame corresponding to the interpolation time,
- wherein the interpolation input frame information indicates position information of a location where each of interpolation input frames is stored in a frame buffer,
- wherein the interpolation input frame information comprises first interpolation input frame information and second interpolation input frame information, and
- wherein the first interpolation input frame information and the second interpolation input frame information respectively correspond to two different time frames.
A method for controlling a display device, the method comprising:
