Abstract:
The present invention relates to a mobile terminal. The present invention relates to a mobile terminal for controlling haptic and a method thereof. The present invention relates to a method for offering the haptic of the mobile terminal comprising a step for detecting a first touch for touching an object displayed on a touch screen; a step for changing the object in response to the continuous motion of the detected first touch and displaying the object; a step for detecting a second touch for touching the displayed object; and a step for displaying visual feedback on the touch screen in response to the detected second touch and outputting haptic feedback which corresponds to a predetermined haptic pattern by using a vibration motor.
Abstract:
The present invention relates to a method for providing a haptic effect in a portable terminal wherein the method comprises: a step of displaying an application screen having a haptic providing area configured by a user on a touch screen; a step of detecting a touch at the haptic providing area; and a step of proving the haptic effect corresponding to the haptic providing area in response to the detected touch, wherein the haptic effect is configured by the user.
Abstract:
PURPOSE: A device and method for generating vibration in a mobile terminal are provided to maximize a haptic effect by combining a visual UI with a vibration level. CONSTITUTION: If some parts of a touch screen area is touched, a plurality of piezoes corresponding to the touch area detects power polarity and power frequency(201,202). The power frequency and polarity of the piezoes are changed into the detected power polarity and power frequency(203). If vibration waves are generated by a power frequency or polarity of the changed piezoes, the vibration level is generated by the overlapping increase or the canceling decrease(204,205).

Abstract:
PURPOSE: An image coding system and method using background characteristic of an image are provided to control a quantization step size for a background region to encode the background region, thereby improving the picture quality of the background image. CONSTITUTION: A image coding system(100) includes a spatial/temporal prediction coding unit(110), a background processing unit(120), a transform coding unit(130), an adaptive quantizer(140), and an entropy coding unit(150). The background processing unit includes a motion judgement part(121), a memory(122) and a background pre-processor(123). The spatial/temporal coding unit carries out motion estimation and motion compensation for an input image to detect a motion vector and carries out spatial/temporal prediction coding for the detected motion vector. The background processing unit compares the prediction-coded image with a previous image and stores temporal continuity of macro-blocks having no motion in the memory. The transform coding unit discrete-cosine-transforms the video data received from the spatial/temporal prediction coding unit. The adaptive quantizer quantizes video data recognized as a background region and video data that is not recognized as a background region. The entropy coding unit variable-length-codes the data output from the adaptive quantizer.
Abstract:
PURPOSE: A formation method of a silicon oxide film is provided to perform a thin film processing with a desirable accuracy in a low pressure condition by controlling a heater block temperature. CONSTITUTION: A reactive gas/ source gas supplied from a reactive gas/ source gas supply unit(124a) is supplied into a process chamber(110) through the first electrode(121). At this time, the source gas for generating a plasma is an ozone and the reactive gas is supplied from a TEOS(Tetra-Ethyl-Ortho-Silicate film). A heater block(130) is installed on the second electrode(122). After stably fixing a pair of wafers(150) on the heater block(130), an accurate temperature control is performed in the range of 350-370 deg.C by a heater block temperature controlling apparatus(140) at the pressure of 1 torr.
