There are provided a user interface apparatus and method using a two-dimensional (2D) image sensor capable of setting an object for an interface from a user image detected by the 2D image sensor and performing a user input accordingly. The user interface apparatus includes: a two-dimensional (2D) image sensor; and a user interface unit detecting a movement of a user captured by the 2D image sensor, setting the detected movement as an object, and outputting the movement of the object detected by the 2D image sensor to a system in which the user intends to establish an interface.

Disclosed are a touch screen apparatus, in which a plurality of touch areas and touch pressure applied to the plurality of touch areas are sensed, and an electronic apparatus having the same. The touch screen apparatus and the electronic apparatus include a touch pad having pressure applied thereto, a plurality of pressure detectors detecting the pressure applied to the touch pad at different positions, and a touch pressure calculator calculating magnitude of pressure applied to a touch position using distances between the touch position calculated by a difference in detection time of the pressure detected by each of the plurality of pressure detectors and each of the plurality of pressure detectors.

Disclosed herein are a method for estimating acoustic velocity of an ultrasonic image and an ultrasonic diagnosis apparatus using the same. The method for estimating acoustic velocity of an ultrasonic image includes: (A) dividing each of the ultrasonic images into a plurality of blocks; (B) extracting contours of ultrasonic images for each block of one frame among the ultrasonic images; (C) calculating and analyzing average luminance values of each block; (D) determining the optimal block number using the average luminance values and selecting the optimal blocks; and (E) estimating and applying the real acoustic velocity, whereby the acoustic velocity is estimated in real time and is applied to the ultrasonic diagnosis apparatus.

There are provided an apparatus and a method of reducing noise. The apparatus of reducing noise includes: an edge determining module determining whether each pixel of an image corresponds to an edge; a low pass filter module performing low pass filtering of the image in two directions, i.e., vertical and horizontal directions and performing low pass filtering only for the pixel determined not to be the edge; a filter selecting module selecting a filter having a flexible size to be applied to a mask region for each of the images low pass filtered in the two directions based on the average brightness of the entire region and the average brightness of the mask region having a predetermined size; a sigma filter module sigma filtering the mask region using the selected filter for each of the images low pass filtered in the two directions; and an averaging module averaging the image sigma filtered in the two directions, thereby making it possible to adaptively reduce noise and prevent loss of the edge due to blurring of the image.

There are provided a method and an apparatus for reducing noise in a digital image capable of reducing noise while preventing damage to an edge of a digital image. The apparatus includes: a high pass filtering unit determining an edge region of an input image; a low pass filtering unit performing low pass filtering on a region of the input image determined not to be the edge region by the high pass filtering unit; and a sigma filtering unit performing sigma filtering on the region of the input image determined not to be the edge region by the high pass filtering unit.
