Abstract:
According to the present invention, a real-time image stabilization method for imaging system including an image sensor, and a motion sensor capable of generating pitch information and yaw information comprising angle values comprises the steps of: segmenting the entire area of an image into a quadrant and previously setting four or more unit search areas including at least one of the quadrant; receiving an image from the image sensor in every frame; receiving, from the motion sensor, a motion sensor signal including at least pitch information and yaw information in every frame; selecting one of four or more unit search areas as a reduced search area, based on unit motion vector consisting of the vertical components of the pitch information and the horizontal components of the yaw information, in every frame; operating motion vector in the selected reduced search area with respect to an image of a current frame and an image of a previous frame, in every frame; and displacing the image of the current frame in a reverse direction of the motion vector operated in every frame to create an image for which the motion of a camera is compensated.

PURPOSE: A wireless power supply device using a UWB and MIMO antenna and a battery controlling method thereof are provided to stably transmit data and prevent interference between wireless signal antennas by controlling the charging of a battery according to the requirement of data transmission. CONSTITUTION: A wireless signal receiver(110) receives a UWB wireless signal and a plurality of MIMO antennas. A battery unit(160) stores power from the wireless signal receiver. A signal converter(120) extracts a data signal from a wireless signal received by the wireless signal receiver. A controller(140) controls the battery unit or signal converter according to the operation of the wireless terminal and the information of the battery unit.

Abstract:
PURPOSE: A method for simulating processor power and a system thereof are provided to prefabricate power consumption about each instruction executed in a processor as look up table, thereby rapidly calculating power consumption about a specific code composed of the instruction. CONSTITUTION: A lookup table unit(120) stores power consumption of an instruction executed in a target processor(110). A code inputting unit(130) receives a target code executed in the target processor. A code power measuring unit(140) measures power consumption about the target code inputted in the code inputting unit by using power consumption information about the instruction stored in the lookup table unit. An optimal code detecting unit detects a minimum power consumption code by comparing power consumption between the target codes when the target codes executing the same function are inputted.
Abstract:
PURPOSE: A Korean alphabet input method in a portable terminal is provided to eliminate additional space key input process by changing a consonant inputted with an initial sound into the end sound of a previous syllable. CONSTITUTION: When characters are inputted in a Korean alphabet input mode, a current input character is determined a consonant or a vowel(S1). In case the current input character is determined as the consonant, the initial sound of the current input character is extracted according to kinds of characters which are just before being inputted(S2). In case the current input character is determined as the vowel, the current input character is outputted(S3).

Abstract:
PURPOSE: A system and a method for cracking down on illegal vehicles using a stereo camera are provided to detect the vehicle using a depth map without removing a surrounding lane. CONSTITUTION: A stereo camera unit(110) includes two cameras. The two cameras take a photograph of an image of vehicles. A control module unit(120) controls the operation and the illumination of the camera. An image conversion unit(130) converts the photographed image into an image with depth information. A violation determining unit(140) determines whether the vehicle violates traffic regulations or not.
