20120249526 | METHOD AND APPARATUS FOR PROCESSING AND DISPLAYING A THREE-DIMENSIONAL IMAGE - A method of processing a 3D image data includes calculating shift values of gray-scales for a reference view using a 3D effect selection signal having a selection depth value of the 3D image inputted by a user. Shift values of the gray-scales respectively corresponding to a plurality of views are calculated using the shift values of the gray-scales for the reference view. The shift values of the gray-scales respectively corresponding to the plurality of views are applied to a source image signal to generate a plurality of image frames. | 10-04-2012 |
20120274628 | 3-DIMENSIONAL DISPLAY DEVICE AND DATA PROCESSING METHOD THEREOF - Provided is a display device. The display device includes a timing controller, a data driving unit, a gate driving unit, and a display panel. The timing controller divides m-bit image data (m is a natural number) received from the outside into n different image data for each viewpoint (n is 2 or larger natural number), and generates an output frame composed of a plurality of 3-dimensional image data including the n image data for each viewpoint. Then, the output frame is dithered so that the image data for each viewpoint expresses m-bit gradation with 1 bit, and image data for each viewpoint included in the output frame are outputted as output image signals. | 11-01-2012 |
20120327079 | DISPLAY APPARATUS AND METHOD OF DISPLAYING THREE-DIMENSIONAL IMAGE USING SAME - A display apparatus includes a display panel configured to include a plurality of pixels and display an image having a plurality of viewpoints in response to a data signal and a control signal, a converter, and a driver. The converter is configured to receive a first image signal and a first control signal, the first image signal including an image data and a depth data corresponding to the image data and a first control signal, the converter further configured to generate a converted depth data corresponding to a predetermined pixel on the basis of the first image signal, and output a second image signal having the viewpoints and a second control signal based on the image data and the converted depth data. The driver is configured to receive the second image signal and the second control signal and output the data signal and the control signal to the display panel. | 12-27-2012 |
20140184653 | IMAGE PROCESSING DEVICE AND DISPLAY DEVICE HAVING THE SAME - An image processing device includes a first filter that filters the image signal to output a first image signal, a second filter that converts the image signal corresponding to a predetermined pixel to a second image signal based on image signals corresponding to a plurality of peripheral pixels adjacent to the predetermined pixel, a third filter that filters the second image signal from the second filter to output a third image signal, a fourth filter that filters the third image signal from the third filter to output a fourth image signal, and an image synthesizer that synthesizes the first image signal from the first filter and the fourth image signal from the fourth filter. | 07-03-2014 |
20140232711 | IMAGE PROCESSING PART, DISPLAY APPARATUS HAVING THE SAME AND METHOD OF PROCESSING AN IMAGE USING THE SAME - An image processing part includes an edge enhancing part, an artifact detecting part and a compensating part. The edge enhancing part emphasizes an edge portion of an object in input image data. The artifact detecting part detects a corner outlier artifact at an area adjacent to the edge portion of the object. The compensating part compensates the corner outlier artifact. Accordingly, the edge portion of the object may be enhanced and the corner outlier artifact is decreased so that the display quality may be improved. | 08-21-2014 |
