| 20080239143 | METHOD AND APPARATUS FOR ADAPTIVELY CONVERTING FRAME RATE BASED ON MOTION VECTOR, AND DISPLAY DEVICE WITH ADAPTIVE FRAME RATE CONVERSION FUNCTION - An interpolation image generation method and apparatus for adaptively converting a frame rate based on a motion vector, and a display device having an adaptive frame rate conversion function are provided. The interpolation image generation method includes an interpolation image generation process calculating motion vectors from a previous image unit and a subsequent image unit that are continuous and generating an interpolation image using the motion vectors; a motion error boundary detection process detecting an area, in which a motion error determined from the motion vectors is greater than a predetermined value, as a boundary area of the interpolation image; and a motion compensation process compensating for a motion error inside the detected boundary area based on a dominant direction of the motion vectors using at least one of the previous image unit and the subsequent image unit. | 10-02-2008 |
| 20090153733 | METHOD AND APPARATUS FOR INTERPOLATING IMAGE - Provided are a method and apparatus for interpolating an image, that improve frequency characteristics of a motion compensated interpolation by combining motion compensation and a de-blurring filter. The image interpolation method includes: estimating a motion vector between adjacent frames; determining a location of a pixel that is to be interpolated between adjacent frames based on the estimated motion vector; selecting values of candidate pixels of the location of the pixel that is to be interpolated; and filtering the values of the candidate pixels by applying each filter coefficient according to locations of pixels to the values of the candidate pixels. | 06-18-2009 |
| 20100110293 | APPARATUS AND METHOD FOR DETERMINING NOISE - A noise determining apparatus is provided. The noise determining apparatus includes a video determiner which determines type of video according to a pre-set criterion, a noise level determiner which determines a level of noise with reference to output from the video determiner, and a noise determiner which determines presence or absence of noise with reference to output from the noise level determiner. Accordingly, incorrect discrimination between a texture area of low level which is similar to noise and noise having a great level difference with respect to neighboring pixels is reduced. | 05-06-2010 |
| 20100150465 | METHOD AND APPARATUS FOR REMOVING IMAGE NOISE - Provided are a method and apparatus for removing image noise. The method includes: separating an input image signal into a signal component and a noise component; converting the noise component into a decorrelated noise component that is spatiotemporally decorrelated from neighboring pixels; and generating an image signal by adding the decorrelated noise component to the signal component. | 06-17-2010 |
