Abstract
A frame rate conversion apparatus and method for an Ultra-High Definition (UD) image. The frame rate conversion apparatus may store a previous frame and a current frame of an edge of an input image, divided into N images, and insert an interpolation frame between the current frame and the previous frame. Also, the frame rate conversion apparatus may convert a frame rate of each of the N images.
Claims15
A frame rate conversion apparatus, comprising:
- N−1 memories to store a previous frame and a current frame of an edge of an input image, the input image being divided into N images;
- and
- N frame rate converters to convert a frame rate of each of the N images by referring to each of the N−1 memories and by interpolating a frame based on the previous frame and the current frame of the input image and then inserting the interpolated frame between the previous frame and the current frame using a delay circuit.
A frame rate conversion method, comprising:
- storing a previous frame and a current frame of an edge of an input image in each of N−1 memories, the input image being divided into N images;
- interpolating a frame based on the previous frame and the current frame of the input image and then inserting the interpolated frame between the previous frame and the current frame using a delay circuit;
- and
- converting a frame rate of each of the N images through N frame rate converters by referring to the stored previous frame and the stored current frame.
A non-transitory computer-readable recording medium storing computer readable code including a program for implementing frame rate conversion method, comprising:
- storing a previous frame and a current frame of an edge of an input image in each of N−1 memories, the input image being divided into N images;
- interpolating a frame based on the previous frame and the current frame of the input image and then inserting the interpolated frame between the previous frame and the current frame using a delay circuit;
- and
- converting a frame rate of each of the N images through N frame rate converters by referring to the stored previous frame and the stored current frame.
A frame rate conversion apparatus, comprising:
- N−1 memories to store a previous frame and a current frame of an edge of an input image, the input image being divided into N images;
- and
- N frame rate converters to convert a frame rate of each of the N images by referring to each of the N−1 memories,
- wherein each of the N frame rate converters further converts the frame rate of each of the N images by performing block-matching with respect to a predetermined macroblock of the previous frame and the current image of the input image.
