IPC: H04B1/59
Filed: 1997-05-02
Abstract: PROBLEM TO BE SOLVED: To prevent unauthorized copying and unauthorized redistribution of digital content media by performing reproduction only in the case that a code word transmitted by a transponder energized by an interrogation from a medium reproducing device and the data word of a digital medium match. SOLUTION: When a medium device such as a digital video disk or the like is inputted to the medium reproducing device, the medium reproducing device transmits interrogation signals to the transponder attached on the disk. Then, when the response signals are received, the transponder is energized. In this case, the transponder responds to the interrogation signals and transmits transponder response signals, including the code word and a prescribed address to the reproducing device for reading the data word on the medium device. When the response signals are received, the medium reproducing device permits the reproduction or use of the medium element, only in the case when the data word read at the prescribed address and the received code word match.

Title: Picture area dividing device, its method and recording medium recording processing program
Inventor: SHIRATANI FUMIYUKI
IPC: G06K9/34
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To obtain a method reducing the erroneous connection mutually between interrupted edge end points and reducing over-divided and over integrated areas and to reduce a processing time by providing a means for lowering a threshold value for deciding the presence/absence of the generation of a dividing stroke until a closed dividing line is obtained. SOLUTION: After setting a target value for evaluating an area and continually setting the primary value and the step size of a threshold value, a picture is inputted to transform coordinates (S1 to 4). Then, adjacent pixel separation degree is calculated and this value is stored (S5, 7). After updating the threshold value next, reporting processing of a pixel is executed based on this threshold value (S6, 8). Continually, whether the target value of each area evaluation is equal to or smaller than a target value is judged and when the evaluation values of all the areas are equal to or smaller than the target value, area separation degree is calculated to reset the separation degree of adjacent pixels (S9 to 11).  After initializing the threshold value based on this reset separation degree, updating of the threshold value, reporting processing of the pixel, evaluation of an area and large/small judgment of the target value are executed. This is repeated until the evaluation values become the target value and an area dividing result is stored at last (S12 to 16).

Filed: 1987-06-18
Abstract: PURPOSE:To generate dot data between the two coordinates of bending point data by determining a line segment to link the interval between the farthest points of the dot areas of the two coordinates and giving the dot data to the coordinate to be close to this line segment. CONSTITUTION:A digital line segment generator generates the dot data of the line segment between a starting point coordinate (XS, YS) and an ending point coordinate (XE, YE) and this device is composed of a line segment determining means and a dot data generating means. The line segment determining means determines the line segment to link the farthest point of the dot area of the starting point coordinate and the farthest point of the dot area of the ending point coordinate. After the line segment to link these two points is determined, the dot data generating means generates the dot data at the coordinate which is between the starting point coordinate and the ending point coordinate and close to the above-mentioned line segment, so that the error of this line segment can be small. Thus, a smooth contour can be derived.

Title: Shift register and image display using the same
Inventor: WASHIO HAJIME
IPC: G09G3/36
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To achieve a shift register that normally operates even when the amplitude of a clock signal is small, and at the same time has less power consumption. SOLUTION: For each SR flip-flop F1 for composing a shift register 11, a level shifter 13 for boosting a clock signal CK is provided, thus the transmission distance of the boosted clock signal and the load capacity of the level shifter 13 are reduced as compared with a case where the clock signal is boosted by only one level shifter for transmitting to each flip-flop. Each level shifter 13 operates while the level shifter 13 at the previous stage outputs a pulse, and stops the operation when the pulse output is completed, thus each level shifter 13 operates only when the clock signal CK is required to be supplied to the corresponding SR flip-flop F1, and as a result the power consumption of the shift register that normally operates even when the amplitude of the clock signal is small can be reduced.

IPC: G06F17/50
Filed: 1995-06-16
Abstract: PURPOSE: To shorten the period required for designing by regularly arranging cells which have regular logic in each block and arranging cells which have irregular logic at their periphery. CONSTITUTION: An LSI is divided into function blocks according to logic design data on the whole LSI. The cells CEL which have regular logic among cells in a block which are arranged at random by a conventional designing method are arranged regularly and the cells CEL which do not have regular logic are arranged at their periphery. Consequently, the regularity of wiring connecting the cells CEL becomes high, so redundant wiring is reduced and a delay value is small and wiring designing with small variance is enabled and the selection range of a wiring path becomes narrow, so the man-hours for the designing decrease and the period required to design the LSI can be shortened.
