Publication number: 20150052474Abstract: A scrolling method and apparatus devices having display screens such as a mobile terminal. When a first image on a screen cannot be moved in a direction by a touch input, a region of the first image is modified in response to the touch input and the modified image is subsequently restored to the first image after the touch is released or a preset amount of time passes. The modification of the region of the image provides an indication that is fed back to the user so that the end or last part of the image is displayed and cannot be moved further, so that undesired repetitive touch input can be prevented.Type: ApplicationFiled: October 30, 2014Publication date: February 19, 2015Inventors: Mee Young KIM, Sung Sik LEE, Kyoung Sik YOON, Byung Joo KIM

Patent number: 7781719Abstract: A new photogate pixel structure for high performance CMOS Image Sensors is proposed. A new photogate structure is incorporated into the photodiode active-pixel structure. The proposed pixel structure exhibits the dynamic integration capacitance characteristics, which can be controlled by varying the control-voltage at the photogate node. Since the sensitivity is inversely proportional to the integration capacitance, the dynamic integration capacitance characteristics can provide the new functionality and controllability for high sensitivity and high dynamic range. At a low voltage level of the photogate, the pixel sensitivity of the new photogate pixel structure is maximized due to the minimum value of the integration capacitance. At a high voltage of the photogate, the dynamic range of the new structure can be maximized due to the increased well capacity. In addition, at an optimum bias voltage of the photogate, both the dynamic-range and the sensitivity can be simultaneously improved.Type: GrantFiled: August 10, 2006Date of Patent: August 24, 2010Assignee: Korea Advanced Institute of Science and TechnologyInventors: Kyoung-Hoon Yang, Sung-Sik Lee
