| 20090038084 | Method for Controlling Operation of the Washing Machine - A washing machine that is capable of providing a stable washing mode even when a washing-related device is abnormal during a washing operation is disclosed. When a steam generation unit, which generates high-temperature steam into a drum, is abnormal, the operation of the steam generation unit is interrupted, and an operation for driving a washing heater mounted in a tub is performed, or an operation for driving a drying unit, which supplies high-temperature dry hot air into the drum, is performed. A steam substituting algorithm is provided when the steam generation unit is abnormal during the operation using the high-temperature steam. Consequently, the interruption of the washing operation due to the abnormal steam injection function is prevented, and therefore, the reliability of the product is improved while the inconvenience of use is minimized. | 02-12-2009 |

| 20120075431 | STEREO IMAGE HANDLING DEVICE AND METHOD - An apparatus and a method for processing a stereo image are provided. In the method, a first image and a second image are obtained via a first camera module and a second camera module installed spaced by a predetermined distance. When the stereo image is captured, the first image and the second image are alternatively sampled with a predetermined time interval. The sampled at least one first image and the sampled at least one second image are encoded. Therefore, the stereo image can be compressed with low complexity compared to the case of compressing a stereo image using a 2D image compression technology. | 03-29-2012 |

| 20090049121 | MOBILE TERMINAL AND METHOD FOR CONTROLLING FUNCTION USING CONTENTS - A mobile terminal and a method for controlling a function of the mobile terminal using contents are disclosed. The contents are authored to include function control information related to the function of the mobile terminal desired to be controlled. The mobile terminal downloads the contents and registers the function desired to be controlled included in the contents to a service table. The application of the mobile terminal does not execute the called function as it is if the predetermined function is called, but identifies if the called function is registered in the service table. If the called function is registered, the application cancels the existing execution routine for the called function and requests the contents player of the service related to the called function. Then, the contents player controls the called function according to a method programmed in the contents. | 02-19-2009 |

| 20090141907 | Method and apparatus for canceling noise from sound input through microphone - Provided is a method and apparatus for canceling noise from a sound signal input through a microphone. The method includes filtering a high-frequency signal having a frequency that is higher than a reference frequency and a low-frequency signal having a frequency that is lower than the reference frequency from input signals obtained through a microphone array, obtaining a high-frequency target signal by canceling a noise signal from the filtered high-frequency signal using a beamforming method, obtaining a low-frequency target signal by canceling a noise signal having a phase difference that is different from a phase difference of a target signal from the filtered low-frequency signal, and obtaining a sound source signal from which noise is cancelled, by synthesizing the obtained high-frequency target signal with the obtained low-frequency target signal. Thus, it is possible to accurately obtain a target sound source signal by minimizing signal distortion occurring in a low-frequency band in a digital sound obtaining apparatus having a small-size microphone array and accurately canceling or attenuating unnecessary noise. | 06-04-2009 |
