Abstract: A position detection system comprising positional element and positioning device, wherein the positional element transmits a continuously modulated acoustic waveform and a synchronization signal that is a sequence of at least two synchronization packets, each bearing timing data for the continuously modulated acoustic waveform. Additionally, the synchronization signal uses time hopping to support concurrent positioning of a plurality of positional elements.

Abstract: A method for processing a frame of image data, wherein the image data is amplified by a gain factor determined in dependence of a number of sub-pixels within said frame of image data having a luminance above a first threshold value. The resulting gain factor allows for optimal amplification of the image data without loss of local detail. This leads to a better perceived image quality. In a preferred embodiment, the gain factor is simultaneously used for reducing the backlight intensity in a backlit LCD device. Thereby, the perceived image quality is similar to that of the unprocessed image data, however the power consumption of the LCD backlight is reduced substantially.

Abstract: An image processing apparatus that performs resolution conversion on image data to output to a display unit includes a resolution converting unit configured to perform resolution conversion on the image data to generate pixel data having a resolution ? times as high as a resolution of the display unit, where ?>1; an image processing unit configured to perform an image processing on the pixel data; and a decimation unit configured to decimate the pixel data on which the image processing has been performed, to have a resolution equal to or lower than the resolution of the display unit, and to output decimated data to the display unit.

Abstract: The apparatus embodies a tilting interface controlling a signal using information regarding a tilt of a handheld device. The apparatus includes a tilt measurement module measuring the tilt of the handheld device; a history storage module storing, in order of time, a history of information regarding the measured tilt of the handheld device and a history of stop position information of the menu list items, the stop position information being created from the signal output according to the information regarding the measured tilt of the handheld device; and a moving speed control module controlling the speed of moving between the menu list items by setting a candidate range, to which a target item desired by a user belongs, using the histories.

Abstract: A computer display includes a screen, a workstation port configured to receive a workstation signal from a workstation controller, and a wireless port configured to receive an external signal from an external device. The external device is different than the workstation controller. The computer display further includes a display circuit coupled to the screen, the workstation port and the wireless port. The display circuit is configured to output (i) workstation information on the screen in response to the workstation signal from the workstation controller and (ii) external information on the screen in response to the external signal from the external device. Accordingly, the user is now capable of enjoying the image quality of a larger video display (e.g., a 15-inches, 17-inches, 19-inches, 21-inches, large projection screens, etc.).

Abstract: A time-to-contact estimation device for estimating a time to contact of a moving body to an object in surroundings of the moving body, includes: an image sensor provided on the moving body, and continuously capturing time-varying images of the surroundings of the moving body; a brightness change calculation unit calculating brightness changes in pixels between the time-varying images captured one after another; and a time-to-contact calculation unit calculating optimized brightness gradients based on the brightness changes calculated by the brightness change calculation unit, and calculating the time to contact of the moving body to the object based on the optimized brightness gradients.
