摘要： Disclosed is a method for extracting a region-of-interest of a user in a multimedia mobile terminal. The method includes: setting a search region in an input picture input to the multimedia mobile terminal on a screen picture-to-screen picture basis, and extracting a group of boundary of a region-of-interest based on a brightness difference between the set search region and an environment around the set search region; determining boundary coordinates of the region-of-interest through learning during a predetermined frame among the extracted group of boundary coordinate candidates; and enlarging the region-of-interest having the determined boundary coordinates, and displaying the enlarged region-of-interest. As a result, a region the user is most interested in or pays more attention to than other regions on a screen is automatically extracted. Accordingly, it is possible for users to view pictures in such an efficient manner as to provide the users with an even better experience and understanding during viewing.

摘要： A deblocking filtering method for image data and a deblocking filter. According to the deblocking filtering method for image data and the deblocking filter, when computation of Boundary Strength (BS) values for each boundary based on one of horizontal and vertical directions from input image data is completed, it is possible to estimate BS values for each boundary based on a direction different from the currently selected direction by using the computed BS values. Further, deblocking filtering is performed based on corresponding directions according to the estimated values, so that the deblocking filtering can be completely performed with only a BS value of boundaries based on a selected one direction. Consequently, a BS value computation process necessarily required in a deblocking filtering process can be considerably reduced, and thus time required in the operation process of a deblocking filter can also be considerably reduced.
