Abstract: A transmitter, including a signal processor programmed to generate, based on input serial data, for each of an integer number of subcarriers mutually orthogonal to each other, a respective first parallel data stream. The signal processor is further programmed to modulate each of the integer number of subcarriers respectively with the respective parallel stream to generate the integer number of data-modulated subcarriers. The signal processor is further programmed to modulate a single carrier occupying a same bandwidth as the integer number of subcarriers with a unique word and one or more pilot symbols to generate a second signal. The signal processor combines the first signal and second signal to generate a third signal. The signal processor generates an output signal by applying a transmit filter to the third signal.

The chromaticity correction device includes a luminance detection unit which detects the luminance value, a backlight driving level detection unit which detects a backlight driving level, a temperature detection unit which detects an internal device temperature or an ambient temperature, a reference luminance value calculation unit which estimates a reference luminance value in a characteristic of an initial state, a chromaticity calculation unit which obtains a chromaticity change amount of white point chromaticity and estimated white point chromaticity that is an estimated value of current white point chromaticity, a chromaticity correction value calculation unit which obtains a chromaticity correction value and a chromaticity correction circuit which corrects the chromaticity of the video signal.

Abstract: A signal transmission system includes a transmission apparatus and a reception apparatus, the transmission apparatus including: a first portion that converts a video signal into differential signals, converts a vertical synchronization signal into a common mode signal, and transmits the converted signals to the reception apparatus via three pairs of signal lines; and a second portion that converts a horizontal synchronization signal into differential signals, converts a first console signal into a common mode signal, transmits the converted signals to the reception apparatus via a single pair of signal lines; the reception apparatus including: a third portion that restores the differential signals to the video signal, and restores the common mode signal to the vertical synchronization signal; and a fourth portion that restores the differential signals to the horizontal synchronization signal, and restores the common mode signal to the first console signal.

Abstract: Non-destructive imaging of an object. An imaging head supported on a rotatable arm samples an electric field scattered by the object at a plurality of locations as the arm rotates about a central axis, with the locations corresponding to a defined spatial domain located remotely from the object. One or more processors execute computer-readable instructions for controlling rotation of the arm and generating a multi-dimensional profile representative of the object in the defined spatial domain based on the sampling.

Abstract: A system and method for displaying an image are provided. In one embodiment, the method includes receiving a data stream representing a frame of an image. The data stream may indicate a first color pixel cluster corresponding to a first color and a second color pixel cluster corresponding to a second color. The first color pixel cluster and the second color pixel cluster may be displayed. The first color pixel cluster may be different from the second color pixel cluster.

Abstract: In one embodiment, the present invention includes a method to convert a pixel tuple in a red, green, blue (RGB) color space having R, G, and B color values into a human recognizable color name corresponding to a range of numerical values of a linear color palette scale based on application of the RGB color values to a predetermined set of hierarchical rules. Other embodiments are described and claimed.

Abstract: A method and system for determining surface topology of a three-dimensional (3D) structure, based on a structured pattern that is projected onto the surface structure, and images of the pattern superposed on the structured surface are analysed to provide surface coordinates of the structure. The pattern comprises a plurality of unique color edges defined between pairs of differently-colored stripes, which substantially overcomes ambiguity problems. In one embodiment, a calibration method is provided enabling the surface coordinates to be obtained from a single image of the structure.

Abstract: The first device receives the video signal to encode a horizontal sync signal and a vertical sync signal of the video signal into a composite sync signal, compresses the composite sync signal into one of three color signals of the video signal, and transmits the three color signals. The second device is in communication with the first device, decompresses the composite sync signal from the compressed color signal, and decodes the horizontal sync signal and the vertical sync signal from the composite sync signal. A method for transmitting video signals and a KVM device are also disclosed.

Abstract: A system and method to provide cost effective, portable and convenient access to the Internet and other personal computer applications from any location within a predetermined distance from a desktop personal computer (PC). According to one aspect, a compact handheld terminal functions as a user interface device and communicates via an FM frequency hopped radio link with a base station which is located near and connected with the desktop PC. The handheld terminal allows home users to conveniently and remotely interface with their desktop PC with a freedom of movement similar to that of using a laptop PC while allowing an inexpensive network connection. The FM frequency hopped radio link carries the appropriate video, audio, keyboard and mouse signals between the desktop PC and the handheld terminal. The approach may be adapted to short range transfer of high quality video in a variety of applications.

Abstract: A low cost image reading apparatus and an image reading method is obtained which allows a high speed image reading process to be performed. When a frame image recorded on a negative film is read, the amount of light of a lamp and the charge accumulation time of a CCD area sensor provided in the prescan section of a film image reading apparatus are fixed. An image buffer is also provided for holding the density values data (the image data) obtained by the fine scan section until the auto setup processing and positive image examination, which are based on the density values data, are completed.

Abstract: In addition to linear conversion parameters V1 to V8 which are used in an interpolation calculation, non-linear conversion parameters VV1 to VV8 are calculated. Each time an input color is fetched, whether the linear conversion parameters are used or the non-linear conversion parameters are used is discriminated. The interpolation calculation of a high precision using the non-linear conversion parameters is performed for a region where it is necessary to guarantee a gradation, thereby preventing a reversal of an output color in a region including an achromatic gradation axis. Regions other than such a region are processed by the interpolation calculation using the linear conversion parameter at a high speed.
