Abstract: A reader for an optical card in which data are recorded along a plurality of tracks on an optical recording medium and optically detected by receiving the light that is emitted from a source of light and reflected by the optical recording medium, which comprises: a memory which records the levels of signals outputted from an optical detector; and a comparator which successively compares the level of an outputted signal stored in the memory with the level of a signal outputted from the optical detector obtained by the next scanning; wherein when the result of comparison indicates that the level outputted from the optical detector is higher than the output level read out of the memory, the content of the memory is replaced by the one that is on the higher level.

Abstract: PURPOSE: To output optical dot information with less error even if a card, e.g., is carried while meandering by reading out a signal corrected to a prescribed output level even when an azimuth angle exists between then direction of a line sensor detecting optical information and the direction of a recording track.
CONSTITUTION: The output 1 of dot information Sa read by a signal in detecting the first scanning signal, e.g., a timing signal T
s is A/D-converted, recorded in the prescribed address of a memory 12 and compared with the output 2 of the dot information Sa read at the next scanning by a digital comparator 13. When the level of a picture element signal read from a line sensor 10 is high, an R/W signal is outputted at the latter half of the clock signal and the memory is controlled into the write mode. Then the data of the address is rewritten into the level value of a picture element signal read at present.

Abstract: PURPOSE:To attain reproduction with high reliability by delaying sequentially each word in the track direction and vertical direction to the track and applying scramble processing to apply error correction at generation of a burst error. CONSTITUTION:A data signal of 16 words per one block of an information data source 11 generating information data to be recorded is converted into data of 20 words per word by a coder 12 generating four check words by an error correction code. The data of the coder 12 is subjected to scramble processing at a circuit 13, where the data is converted into data of 20 words per block and it is extracted from an output terminal 14. Cutting data at the terminal 14 is recorded respectively to each track of a strip region of an optical recording card by one block each.

Abstract: PROBLEM TO BE SOLVED: To drastically shorten a time required for collating fingerprints by a template and also to keep collection performance in the case of the deformation of a finger. SOLUTION: It is judged whether or not a collation picture which is obtained by binarizing an inputted digital image for fingerprint collation through the use of a proper method coincides in fingerprint with a register image whose register template is extracted by matching with a plurality of pre-registered register templates. Then position relation is checked only between detected addresses in the adjacent templates in place of checking position relation between the addresses of whole points with a high coincidence degree which are detected concerning the respective templates. Thus, a number for combination is drastically reduced and a rapid processing is performed. Besides, the processing is performed only between the physically near templates so that the deformation of the finger is no problem in comparison with the case that the processing is performed between remote templates.

Abstract: PROBLEM TO BE SOLVED: To give permission of use only to a specified user, in a system which delivers digital contents. SOLUTION: When delivering the contents of video, music or application software from a server S to a user N, each of contents is enciphered by a session key and sent and an enciphered session key is sent to the user N. Namely, the delivery of contents and the delivery of the session key for restoring these contents are conducted separately. For the contents and a unit number or enciphered session key, a method for transmitting digital data to a specified receiver like digital broadcasting or the Internet or delivering packaged data by a physical means such as home delivery or mail service is to be used.
