Technologies are generally described for estimating a quality of experience based on movements of a mobile device in a telecommunication system. In addition, the invention relates to a method for attaching such a strain relief device. The system further allows users to select one or more web sites for customizing web search and querying the preselected sites using user input keywords. In carrying out G component interpolation processing, a determination is made as to the G components of which pixels to use in the interpolation processing based on R components or B components of the image data that has undergone magnification chromatic aberration correction processing. The chip is disposed in a chip mounting region of the flexible substrate.
