Abstract
Disclosed is a frame interpolating apparatus and a method thereof used at a frame rate conversion. The frame interpolating apparatus includes a calculation unit for performing a SAD Map calculation among inputted video signals with respect to a previous frame and a next frame and performing block matching, a determination unit for determining from the block-matched frame whether a video is repeated periodically and is changing fast, and an interpolation unit for selectively calculating a pixel value of an interpolated frame according to a determination result of the determination unit. Accordingly, the interpolated frame is vivid and clear, hence, removing the conventional blurring problem.
Claims18
A frame interpolating apparatus used for converting a frame rate, comprising:
- a calculation unit performing a Sum of Absolute Difference (SAD) map calculation among inputted video signals with respect to a previous frame and a next frame, and performing block matching to output a block-matched frame;
- a determination unit determining from the block-matched frame whether a video is repeated periodically and/or changing fast;
- and
- an interpolation unit selectively calculating a pixel value of an interpolated frame according to a determination result of the determination unit,
- wherein if the video has a repetition pattern, the interpolation unit interpolates the video using a pixel value of the previous frame.
A frame interpolating method, comprising the steps of:
- setting a block for a previous frame and a next frame;
- searching for a matching block by performing a Sum of Absolute Differences (SAD) mapping calculation;
- determining whether a video signal of the matching block has a repetition pattern;
- and
- if it is determined that the video signal has the repetition pattern, interpolating with a pixel value of the previous frame.
A frame interpolating apparatus used for converting a frame rate, comprising:
- a calculation unit comparing inputted video signals with respect to a previous frame and a next frame to output a differential value, and performing block matching to output a block-matched frame;
- a determination unit determining from the block-matched frame whether a video is repeated periodically and/or changing fast;
- and
- an interpolation unit selectively calculating a pixel value of an interpolated frame according to a determination result of the determination unit,
- wherein if the video has a repetition pattern, the interpolation unit interpolates the video using a pixel value of the previous frame.
