摘要： A display apparatus and a method of displaying an image using the display apparatus. The display apparatus includes a classifier to detect whether a pixel of each line of sequentially input frames of an input image is a black pixel of a letter-box area, a counter to count a number of black pixels detected in each line, a determiner to determine a maximum value of consecutive black pixels in each line, a letter-box detector to detect a boundary of the letter-box area in each frame using the number of black pixels and the maximum value of consecutive black pixels of each line, a boundary determiner to determine final boundaries of the letter-box area by determining a line as one of the final boundaries of the letter-box area if the line is detected as the boundary of the letter-box area a predetermined number of times or more in the frames of the input image, and an adjuster to adjust a size of the input image such that an image area within the final boundaries of the letter-box area is fit to a size of a screen

摘要： An image processing apparatus using a judder-map and a method thereof. The image processing apparatus using a judder-map includes: a field storage block to receive an input interlaced video signal including an input image having a plurality of consecutive fields, a film detecting block to receive the plurality of the consecutive fields from the field storage block and to detect whether the input image is an image in a film mode, a judder-map generating block to detect judder created on a pixel or block of neighboring fields among the plurality of consecutive fields provided from the field storage block to generate a judder-map, and an image interpolating block to perform image interpolation using the judder-map if the input video signal is detected to be an image in the film mode and to generate and output a progressive video signal. The image processing apparatus prevents the creation of judder on CGI (Computer Graphic Imagery) or subtitles, to which pulldown technologies are not applied.

摘要： A film mode detection apparatus capable of detecting a bad edit and a method thereof that can detect a bad edit independently of a film pattern. The film mode detection apparatus includes a pattern generation unit to generate a pattern using difference values of information between sequential fields of an input image, a bad edit detection unit to detect extremum values of the difference values of the information between the fields and to judge whether a present field corresponds to a bad edit according to variances of the detected extremum values, and a decision unit to decide whether the input image is a film image using pattern information generated from the pattern generation unit and bad edit detection information from the bad edit detection unit. Accordingly, the apparatus can cope with all kinds of bad edits and thus can prevent an error during the judgment of a film mode.

摘要： A coupling structure for an air guide of a front end module includes a plurality of rib members formed at a lateral portion of the front end module, at least one support ribs protruding from a fixing surface of the air guide, and a plurality of insert blades extending at a right angle at one end of the respective support ribs. Each of the rib members is formed about an associated guidance recess, and includes a pair of lateral ribs protruding from opposite lateral sides of the guidance recess, and a pair of front ribs extending from distal ends of the lateral ribs toward each other. The support ribs are configured to be inserted along the guidance recesses of the rib members, respectively, and in such an inserted state of the support ribs, the insert blades connected thereto come into contact with inner surfaces of the front ribs of the rib members.

The apparatus includes a main detection unit for calculating a summed absolute difference (SAD) between sequential fields with respect to an input image signal and detecting a 2:2 pull-down image based on the SADs, a sub-detection unit for calculating an absolute change amount between the SADs and detecting the 2:2 pull-down image based on the absolute change amounts, a still image judgment unit for judging whether the input image signal is a still image, and a 2:2 pull-down sequence decision unit for deciding whether the input image signal is the 2:2 pull-down sequence. The apparatus can accurately detect the 2:2 pull-down image by adaptively coping with the changed picture even in the case of much noise.
