    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 host controller, a secure element, and a serial peripheral interface communications system are provided. The host controller is configured to connect to a secure element via a serial peripheral interface and includes: a resume signal generator configured to generate a first resume signal indicating a start of communication with the secure element; a transmitter configured to transmit the first resume signal to the secure element; a slave select line activator configured to activate a slave select line after the first resume signal is transmitted; and a clock controller configured to transmit a first clock signal to the secure element over a clock line based on the slave select line being activated, and the transmitter is further configured to transmit a first signal containing first data to the secure element over a master-out slave-in line (an MOSI line) while the first clock signal is being transmitted.

    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.
