20090046208 | IMAGE PROCESSING METHOD AND APPARATUS FOR GENERATING INTERMEDIATE FRAME IMAGE - Image processing method and apparatus for creating an image of an intermediate frame are provided. The image processing method generates a background image and a first motion image using a current frame and a previous frame, and generates a second motion image of the intermediate frame using either the current frame or the previous frame. Accordingly, it is possible to minimize the interpolation error in the boundary area vulnerable to the motion estimation error. | 02-19-2009 |
20090146914 | DISPLAY APPARATUS AND METHOD FOR DISPLAYING 3-DIMENTIONAL IMAGE - A display apparatus and method for displaying a 3D image using a left-eye image signal and a right-eye image signal are provided. The display apparatus includes an image signal division unit which divides an image signal into a plurality of subfields, and a control unit which arranges the plurality of subfields according to luminance weights of the plurality of subfields. Accordingly, the user can be provided with 3D images having high tone and high image quality while preventing the occurrence of double images. | 06-11-2009 |
20120120055 | THREE-DIMENSIONAL IMAGE PROCESSING APPARATUS AND THREE-DIMENSIONAL IMAGE PROCESSING METHOD - Provided are an image processing apparatus and an image processing method, the image processing apparatus including: a parallax estimation unit which estimates parallax with respect to a left eye image and a right eye image of a three-dimensional (3D) image; a horizontal movement value determination unit which determines a horizontal movement value using the estimated parallax; a horizontal movement unit which horizontally moves the left eye image and the right eye image based on the horizontal movement value; and a controller which calculates a chronological change rate of the estimated parallax for a predetermined time, determines whether the chronological change rate is greater than a predetermined threshold, and if the chronological change rate is greater, limits the horizontal movement value to a predetermined range and controls the horizontal movement unit to horizontally move the left eye image and the right eye image based on the limited horizontal movement value. | 05-17-2012 |
20120201449 | IMAGE PROCESSING APPARATUS AND CONTROL METHOD THEREOF - An image processing apparatus and a control method thereof are provided. The an image processing apparatus includes: a depth map estimating unit which estimates a depth map of a stereoscopic image; a region setup unit which sets up a region in the stereoscopic image; and a 3D effect adjusting unit which determines a difference in a depth level between the setup region and a surrounding region other than the setup region based on the estimated depth map, and adjusts a 3D effect of the stereoscopic image based on the determined difference in the depth level. | 08-09-2012 |
20130094754 | IMAGE OUTPUT APPARATUS AND METHOD FOR OUTPUTTING IMAGE THEREOF - An image output apparatus and a method for outputting an image thereof are provided. The method of the image output apparatus determines whether a difference in grayscale values between a current image frame and a previous image frame is greater than or equal to a pre-set value, if the difference in the grayscale values is greater than or equal to the pre-set value, at least one of a maximum grayscale value and a minimum grayscale value of the current image frame is adjusted, a grayscale of the current image frame according to an input and output grayscale function having the adjusted maximum grayscale value and minimum grayscale value is adjusted and an image is output. Accordingly, a crosstalk phenomenon of a | 04-18-2013 |
20130169663 | APPARATUS AND METHOD FOR DISPLAYING IMAGES AND APPARATUS AND METHOD FOR PROCESSING IMAGES - An apparatus and method for displaying images and an apparatus and method for processing images are provided. The image display apparatus includes an image processor configured to receive an image frame and convert a gradation value of each of a plurality of pixels constituting the image frame to generate a sub image frame; and a controller configured to control a display panel to sequentially display the image frame and the sub image frame. | 07-04-2013 |
20150103108 | DISPLAY DEVICE AND METHOD THEREOF - A display apparatus includes: a display panel configured to display an image frame; an arithmetic operator configured to divide the image frame into blocks, calculate a pixel gradation value of the pixel blocks, and accumulate the calculated pixel gradation values; and a compensator configured to locally reduce a luminance of a corresponding pixel block, of which a respective accumulated pixel gradation value exceeds a threshold value of among the plurality of pixel blocks, and to compensate for a luminance difference between the corresponding pixel block, for which the luminance has been reduced, and surrounding pixel blocks. Accordingly, it is possible to effectively remove an afterimage. | 04-16-2015 |
20150287355 | DISPLAY APPARATUS AND CONTROLLING METHOD THEREOF - A display apparatus is provided. The display apparatus includes: an image input configured to receive an image; a display panel configured to include a plurality of pixels and respectively emit light in the plurality of pixels in order to display the image; a panel driver configured to drive the display panel; and a controller configured to analyze a motion of the image and control the panel driver to drive the display panel by using different driving methods according to a size of the analyzed motion. | 10-08-2015 |
