Abstract: In a multi-hop radio communication network including a base station (a radio station connected to a management server), each radio station in the network is given a data transmission opportunity in turn according to a predetermined transmission order, and transmits data via broadcast or multicast upon occurrence of transmission timing. The radio station having received the data adds data of the radio station to the received data and then forwards the packet via broadcast or multicast when it is the radio station's turn for transmission.

Abstract: An image display device includes a pair of transparent substrates, a liquid crystal composition and at least two types of color filters disposed between the pair of substrates, at least two types of light sources, and a light source controller. Each of the light sources generating peak wavelengths of at least two colors, wherein the peak wavelengths are different from one another. The light source controller switches on and off the light sources in time sequence within one frame period.

Abstract: An image formation apparatus includes an aperiodic data generating unit for generating aperiodic data between pixel areas having a neighboring relation every pixel area comprising a plurality of pixels having an interlocking relation of the image data, a threshold value deciding unit for converting the aperiodic data into a plurality of threshold data for forming a systematic dot array in the pixel area, and a gradation conversion processing unit for performing a gradation converting process by comparing the image data with the threshold data, thereby reducing a signal processing amount as compared with that in case of performing the propagating process on a pixel unit basis.

Abstract: A multi-color display system operates to suppress deterioration in resolution and increase in power consumption or deterioration in brightness. The multi-color display system includes n types of spectrum selecting means; m types of light sources each having a different spectral distribution; light source controlling means for controlling, on a time-division basis, emissions from the m types of light sources; color light sources controlled by the light source controlling means and the n types of spectrum selecting means, the number of the color light sources being not less than n+1, but not more than n×m; and a light valve for controlling transmittance or reflectance of light in accordance with image information.

Abstract: A micro-controller includes a dictionary memory for storing instruction codes which appear in a program, and a compressed code memory for storing compressed codes each converted from each of the instruction codes included in the program. Each compressed code has a word length sufficiently long to identify all instruction codes included in the program. Each compressed code has a value indicative of an address in the dictionary memory at which an associated instruction code is stored. The micro-controller is responsive to an instruction code read request which specifies an address of a compressed code to read the compressed code stored in the specified address in the compressed code memory, and to subsequently read an instruction code stored in an address indicated by the compressed code in the dictionary memory.

Abstract: A color correction table which contains a correspondence relationship between a discrete input color signal and an output color signal is employed. An inputted color signal is corrected by a signal correcting unit, and an approximating unit acquires a discrete input color signal approximated to the corrected input color signal. A table referring unit refers to the color correction table to output an output color signal which corresponds to the input color signal approximated by the approximating unit. An approximate error producing unit calculates an approximate error from difference between the input and output signals supplied to the approximating unit, and then stores this calculated approximate error into a data holding unit. The stored approximate error is supplied to a signal correcting unit to be used in the correction of the input signal.
