Abstract: A receiver of a near field communication device includes a local oscillator, a first channel, and a second channel. The local oscillator may be configured to generate a first local oscillating signal. The first channel may be configured to process an input signal by mixing the input signal with the first local oscillating signal. The second channel may be configured to process the input signal by mixing the input signal with a second local oscillating signal that has a phase difference of 90 degrees with respect to the first local oscillating signal. Each of the first and second channels may include a comparator unit that includes a comparator configured to compare, in a comparator mode, an amplifier output signal with a reference voltage whose level increases in a step-wise manner and the comparator unit may be configured to set a level of the reference voltage to be used in a normal mode based on an output signal of the comparator.

Abstract: A method and an apparatus are provided for displaying a portrait on a display by a portable terminal. It is determined whether an image is a character-photographed image. If the image is the character-photographed image, face detection is executed from the image. A character area in the image is set based on a result of the face detection. The character area is enlarged and displayed in a form of a new window.

Abstract: An apparatus and method are provided for performing detail enhancement. The apparatus includes an edge detector that detects an edge pixel from contents based on a luminance component of the contents, a histogram analyzer that generates at least one histogram with respect to the edge pixel and determines a gain variable value of the edge pixel based on the at least one histogram, and a gain regulator that determines a gain corresponding to the gain variable value of the edge pixel.
