Abstract: PURPOSE:To prolong the life of an LCD driving IC by preventing a harmful voltage generated in a power-OFF state from being applied. CONSTITUTION:A smoothing capacitor 5 and an SSR 6 which short-circuits the capacitor 5 are connected to the output terminal of a DC-DC converter 4, which drives a liquid crystal display(LCD), in parallel. When power supply to the LCD is cut off, a PNP type TR 1 is turned OFF and a DC power VDC (+5V) as input electric power to the DC-DC converter 4 is turned OFF. At the same time, the SSR 6 is placed in operation to short-circuit the capacitor 5. Consequently, electric charges accumulated in the capacitor 5 are discharged to speedily reset minus electric power (VLCD) to the LCD to 0V.

Abstract: PURPOSE:To shorten optical path length by providing a photoelectric converting means to convert light transmitted through an optical system into a picture signal, a compensation signal generating means to generate a compensation signal to compensate the characteristic of the optical system, and a correcting means to correct the picture signal according to the compensation signal. CONSTITUTION:An optical system compensation signal generator 16 generates the compensation signal (e) to compensate the attenuation of peripheral light quantity caused by the edge effect of an imaging lens 10. Namely, since the light quantity of a peripheral part is less than the light quantity of a central part, the level of an analog picture signal from a CCD 11 in the case of full- white input falls at the peripheral part as shown by a full line. In order to compensate this fall of the level of the peripheral part, the signal (e) in which the peripheral part is set larger than '1' assuming that the central part is '1' is used. This signal (e) is supplied to a multiplier 13, and raises the level of the peripheral signal level of the analog picture signal (b) from the CCD 11. Thus, the analog picture signal (f) flat extending over the full width of the CCD 11 for the full-white input can be obtained from the multiplier 13.

Abstract: PURPOSE:To efficiently store data by encoding image data by an incorporated data compressing means to write it and decoding this data by a data expanding means in case of read-out. CONSTITUTION:Original image data inputted from an external bus EB are inputted to a compressing circuit 2 through a data switching circuit 1 and an internal bus IB1. The circuit compresses data in accordance with the modified Huffman code system or the like and writes and stores data in a memory 4. Compressed data read out from the memory 4 is inputted to an expanding circuit 3 and is expanded to original data and is outputted to the bus EB through an internal bus IB3. In case of input/output of encoded character data, the data are written in and read out from the memory 4 through buses EB and IB2. Consequently, the image data are efficiently stored.

Abstract: PURPOSE:To reduce vacancy of an arithmetic section and heighten efficiency of processing by inputting data from an outside bus utilizing intervals of output of a data memory. CONSTITUTION:When making ring bus connection, data are inputted from an outside bus utilizing intervals of output of a data memory at the time of waiting of data for dyadic operation which can be expected to occur fairly frequently. By inputting data outputted from the data memory through a link table memory and a function table memory to the second cue memory, disturbance of pipe line processing due to data inputting from an outside bus is eliminated. Thus, by improving efficiency of processing and eliminating complicated control between bus interface and a processor unit and making the scale of hardware, a data flow processing device smaller and cheaper than conventional one is obtained.

CONSTITUTION:When a control circuit 1 repeats discharging and charging of a battery 7 a plurality of times, a charge circuit 2 starts the charging upon receiving a charge starting signal from the circuit 1 and, upon completing the charging signal to the circuit 3. A discharge circuit 3, on the other hand, starts the discharging upon receiving a discharge starting signal from the circuit 1 and, upon completing the discharging, outputs a discharge completing signal to the circuit 1. A discharging time measuring circuit 4 starts measurement upon receiving a measurement starting signal from the circuit 1 at the time of starting, for example, the third discharging operations, stops the measurement upon receiving a discharge completing signal from the circuit 3, and outputs the measured time, namely, the time required for discharging the battery 7 to a display circuit 5.

Abstract: PURPOSE:To obtain a fingerprint image of high quality without any aid of sweat from a skin by providing a one-dimensional image sensor having an imaging system and a lighting means for uniformly illuminating the line-shaped image pickup range of the sensor, and detecting the difference of a reflection condition. CONSTITUTION:Transparent glass 1-1 so curved as to form a concentric circular cylinder in internal and external surfaces is used as a seat to place a finger FNG in a fingerprint detecting part 1. An image sensor 1-2 and a lighting unit 1-3 are fixed at such a position having a relationship to meet a total reflection condition on the surface of an elastic film 1-7 formed on the internal surface of the curved glass 1-1. The aforesaid image sensor 1-2 detects and outputs an image on the surface of the elastic film 1-7 on the internal surface of the curved glass 1-1 via an optical fiber lens 1-6. That is, the elastic film 1-7 is deformed due to the crest of a fingerprint and the total reflection condition of light is disordered in the deformed position. Consequently, a light reflection amount is different between the crest and trough portions of the fingerprint and the strength difference is converted into an electric signal via the image sensor 1-2. According to the aforesaid construction, it is possible to detect the image of the fingerprint along the curvature thereof.

Abstract: PURPOSE:To automatize the operation of the titled device by knowing the placing of a finger with total reflecting light from a fingerprint on a bent glass and outputting a mechanical driving signal when the area of the peak part of the fingerprint is more than a prescribed one. CONSTITUTION:When the finger is placed on a bent glass body, a value lower than that of a binarization slice level is obtained at the peak part of the fingerprint, and the rate increases in accordance with the increase of the quantity of perspiration. Consequently, by observing the output of a comparator 6, it can be known whether or not the finger is placed. A counting circuit 8 counts the number of signals 1 outputted from the comparator 6 during number of 32 times of main scannings. That is, the area of the crest part of the fingerprint is obtained. A comparator 9, when the output of a counting circuit 7 is larger than the value set at a constant setting circuit 10, namely when the crest part of the fingerprint goes to be more than the area set at the constant setting circuit 10, outputs a mechanical driving starting signal.

Abstract: PURPOSE: To calculate an accurate pattern position shift amount by estimating the revolving center of a pattern to be collated from a comparatively small error circle and changing the radius of said error circle in proportion to the distance from the revolving center of the pattern.
CONSTITUTION: An error circle generating circuit 4 obtains the revolving center of a pattern to be collated from the input distance and inclination, the revolving angle of each corresponding partial area read out of a data memory 1 and the position coordinates of a partial area of a pattern to be collated. The circuit 4 produces an error circle having a radius proportional to the distance from the revolving center of the pattern and supplies it to an accumulation memory 5. A correspondence selection circuit 6 gives the raster scan to the memory 5 to detect a part having the maximum accumulation frequency of the error circle and then supplies the position coordinates of a partial area where the error circle is drawn to a shift amount calculation circuit 7. The circuit 7 calculates both a revolving angle and a parallel shift amount form a pair of input position coordinates and delivers them.
