Abstract: PROBLEM TO BE SOLVED: To perform always accurate fingerprint collation without being affected by a personal error due to an unclear fingerprint, a finger pressure in reading a fingerprint and the drying condition of a finger. SOLUTION: When image input means reads the fingerprint and outputs an image signal for the fingerprint, an A/D converter digitizes the image signal and outputs variable density image data for the fingerprint. First image binarizing means 24 detects a position where the gray level image data 22A is at the maximum value and forms binarized image data which is '1' near the position and '0' at the other positions. On the other hand, second image binarizing means 26 detects a position where the variable gray level image data is at the minimum value and forms second binarized image data 34 which is '0' near the position and '1' at the other positions. Fingerprint determining means 38 determines whether the fingerprint is a specified fingerprint or not using the first and second binarized data 32, 34.

Abstract: PROBLEM TO BE SOLVED: To simply and also surely detect a characteristic part by accumulating operation processing results in a direction that orthogonally crosses a shift direction, detecting an accumulation distribution where accumulated values successively continue in the shift direction, detecting a peak value of accumulation value from the accumulation distribution and deciding the characteristic part of a fingerprint image. SOLUTION: When operation processing result data that successively continue in a vertical direction are sequentially read, operation processing result data of values 0 which comprise black pixels are accumulated and the last operation processing result data in a vertical direction are accumulated, vertical addresses j exceed the number of pixels in a vertical direction (S18). In such a case, a system control circuit compares the value of a count value register (cnt) with the content of a maximum count value register (max) (S19). When the value of the register (cnt) is the value recorded on, the register (max) or more, the system control circuit records the content of the register (cnt) on the register (max) (S20).

Abstract: PROBLEM TO BE SOLVED: To surely fetch a fingerprint image by detecting pulsations of a luminance level from a fingerprint image inputted by an image inputting means and starting processing of the fingerprint image when the pulsation increases to a prescribed decision level or more. SOLUTION: A fingerprint collating device 1 controls the entire operation by a system control circuit 3 in response to a user's operation that is inputted through a key inputting part 2. That is, the device 1 detects pulsations of a luminance level in a fingerprint image by a fingerprint data inputting part 4 and outputs the data DM of a pulsation detection result to the circuit 3 at the time of registering fingerprint data D1 and also collating it. The circuit 3 discriminates a data DM that is of a prescribed level or more, detects a state in which a finger is stably and also surely placed on a prescribed finger mounted position, waits for the state detection, fetches the fingerprint data D1 to an inspection fingerprint memory 6 and processes it.

Abstract: PROBLEM TO BE SOLVED: To simply and surely judge coincidence or noncoincidence concerning the picture of a fingerprint, etc., by successively displacing plural areas from which a first picture is segmented on a second picture so as to judge the coincidence of the picture from the peak value of distribution tabulation obtained from the detection, etc., of the coincidence of each area and the second area. SOLUTION: In response to user's operation, fingerprint data D2 in an inspected fingerprint memory 6 and corresponding fingerprint data D1 registered in a fingerprint data base 5 are inputted in a collating ratio detecting part 7. The part 7 successively obtains comparing results between the linear picture of data D1 and a picture by data D2 overlapping at each displacing position to successively detect coincidence between each linear picture of data D1 and the picture of data D2. In addition, the distribution of coincidence is detected. In addition, the distribution of coincidence is corrected and the collating ratio is calculated between fingerprint pictures by data D1 and D2 from this corrected result to judge coincidence/noncoincidence by this collating ratio.

Abstract: PURPOSE:To reproduce at high speed by equipping an optical system for reproducing, which includes an area image sensor, to an optical card, for which plural recording units to be composed of linear track strings are recorded in a matrix shape. CONSTITUTION:To an optical card 1, a digital signal is recorded as the track string and the plural recording units (blocks) of the track strings in a prescribed number are recorded in a matrix shape. A reproducing light from a light emitting diode 6 as a light source for reproducing covers the whole range of one block and the light is image-formed through a magnifying lens to an area image sensor 11 of a CCD. A signal from the sensor 11 is digitized and written to a memory. The reproducing data of the respective track strings are read from the memory and the part of a silent signal is detected. Then, the maximum value of a signal between the respective silent signal parts is calculated and held to a line memory for one track string. The reproducing data are successively read from this line memory. Then, the high speed reproducing can be executed by the area image sensor.

Abstract: PROBLEM TO BE SOLVED: To provide a device which records additional information difficult to analyze to an information recording medium and reproduces the additional information, and also provide a medium and a method therefor. SOLUTION: When additional data, for example, key information applied for decoding content, key generation information, content reproduction control information, copy control information and so on, are recorded to an information recording medium, the parity of user control data (UCD) is set to be "an even number" or "an odd number" by controlling the configuration bit of a data-changeable data part, for example, the user control data, in accordance with the configuration bit information of the additional data, that is, "0" or "1", and the parity of a recording frame corresponding to specifically selected addition data, that is, "an even number" or "an odd number". When the data are reproduced, the additional configuration bit information, that is, "0" or "1", is obtained by detecting the parity of the recording frame corresponding to the additional data and the parity of the configuration data of the user control data (UCD).

Abstract: PURPOSE:To accurately reproduce digital information by recording a clock track recorded with clock information for reproducing digital information between data tracks at prescribed number of the data tracks intervals. CONSTITUTION:An area where audio data are digital recorded is limited to the whole areas except the recording area of video information and the recording area of analog audio information. Thus, a gap part 61 between an analog sound track 53 and a video recording part 51 is made a digital sound track, and the audio data are recorded on the digital sound track 52 in a direction perpendicular to the advancing direction of a cinema film as track lines parallel to each other. Then, the audio data are reproduced accurately since a reproducing clock track is recorded between plural data track lines where the audio data are recorded at the data track interval, and the audio data are outputted after a positional error is compensated.
