Abstract: An apparatus and a method for sharpening a blurred blown-up image are provided to remove blurring of the magnified image by using an edge-adaptive clearing method without a side effect such as ringing or artifact, thereby clearing the magnified image. A digital image processor(20) comprises the followings. A main edge direction calculator(21) includes a digital filter, and extracts brightness of an inputted image. A first high pass calculator(23) selects one direction of 0, 90, 135 or 45 degrees as a main edge direction. By obtaining a difference value of the main edge direction, the first high pass calculator obtains a high pass filtering value in correspondence with the main edge direction. A second high pass calculator(24) obtains a general high pass filtering value. An adaptive digital filtering unit(25) adaptively mixes the high pass filtering value, filtered from the first high pass calculator, and the general high pass filtering value, filtered by the second high pass calculator, according to an edge direction deviation. Therefore, the adaptive digital filtering unit obtains a digital filtering value.

Abstract: A mouse interface device using a camera, a system and a method using the same, and a computer-readable recording medium thereof are provided to control a position of a mouse cursor in a screen without any additional device by using homography converting a coordinate system of a camera into a planar coordinate system of the screen. An image coordinate detecting module(310) detects image coordinates, which are positions of at least four points found on an edge of a screen from a camera image, from the screen captured by a camera(100). A homography processing module(320) finds homography by using the detected image coordinates and planar coordinates, which are the planar coordinates formed by the screen for the predetermined points. The homography comprises a 3X3 matrix converting a coordinate system of the camera into a planar coordinate system of the screen. A cursor coordinate outputting module(330) outputs screen coordinates for the predetermined point of the camera image by using the homography and determines the screen coordinates as the position of the cursor. A mouse driver(400) moves the position of the cursor according to a change of the determined coordinates.
