Abstract: A display apparatus and a method for video calling thereof are provided. The method includes: capturing an image; detecting a face of at least one user from the captured image; setting an interest area to include a preset body part of the at least one user whose face has been detected; editing the interest area set in the captured image to generate a video calling image; and transmitting the video calling image to an external apparatus.

Abstract: A display apparatus of a display system which includes a plurality of display apparatuses including: a display unit; a signal processor which processes an image signal supplied from outside, based on setting information stored in advance in the display apparatus, which displays an image on the display unit based on the processed image signal; a connector which is connected to an external storage device which stores the setting information of the display apparatus; and a controller which, if the external storage device is connected to the connector at a time when the setting information of the display apparatus is initially set, obtains the setting information from the external storage device and stores the setting information in the display apparatus, and updates the setting information stored in the external storage device corresponding to another display apparatus of the plurality of display apparatuses.

Abstract: A display apparatus and a controlling method thereof are provided. The controlling method of a display apparatus includes displaying a mode conversion user interface (UI) that provides a guideline to enter a motion task mode; recognizing a first motion that corresponds to the guideline; entering the motion task mode that enables a second motion to control a function of the display apparatus in response to the first motion being recognized while the guideline is displayed on the display apparatus; and displaying a motion task UI to perform the motion task mode.

Abstract: An image processing apparatus includes: a camera configured to generate a captured image by capturing motion of an object; an image processor configured to process the captured image; a storage configured to store a predetermined information which is common data included in common in a plurality of motion history images (MHI) obtained by capturing respectively the motions by a predetermined form; and a controller configured to determine that a form of the motion by the object within the captured image corresponds to the predetermined form if it is determined that MHI data of the captured image includes the predetermined information.

Abstract: The present invention relates to a process of preparing a continuous filament composed of a nano fiber, wherein nano fibers are prepared by spinning a polymer spinning dope in a spinning dope main tank (20) onto the surface of water or organic solvent (4a) of a collector (4), which contains water or inorganic solvent (4a) and has a conductive material (5) with a high voltage applied sunken in the water or organic solvent (4a), through nozzles (2) with a high voltage applied, and the nano fibers are pressed, drawn, dried and wound while being pulled by a rotary roller (6) rotating at a constant linear velocity from the location spaced more than 1 cm from one end of a dropping spot. The present invention can prepare a continuous filament composed of a nano fiber by an electrospinning method and a continuous process.
