Title: Picture processor
Inventor: FUKUDA MIKA
IPC: G06T9/00
Filed: 1988-12-29
Abstract: PURPOSE:To classify a data with characters and a picture in mixture into a character part and a picture part by providing a means dividing an original picture into small blocks, a means dividing the original picture into large blocks, a means obtaining a conversion coefficient block, a means classifying the original picture into a gradation pattern and a means classifying the original picture into an area block. CONSTITUTION:An original picture is divided into nXn blocks by a small block divider 31, a conversion coefficient block is obtained by applying orthogonal conversion to each block and classified into plural gradation patterns by using a gradation pattern classifying device 33. Then a large block divider 34 is used to divide the original picture into NXN large blocks, an area block classifying device 35 is used to count number of gradation patterns in existence in each large block, and the original picture is classified into a low gradation area block representing mainly the character area and a high gradation area block representing mainly a natural picture depending on the number. Since the data having characters and a natural picture in mixture is classified into the character part and the natural picture part by using the frequency characteristic of the picture, the classification is attained without notice of the user.

Title: Paper charging device
Inventor: HIROMI TAKU
IPC: B65H5/06
Filed: 1987-12-28
Abstract: PURPOSE:To remarkably reduce noise just after the start of paper charging by providing a feed control means which controls at least either of a paper charging roller and a regist roller so as to reduce the clashing speed of a paper against a guide plate or the like. CONSTITUTION:After the tip of a paper P was brought into contact with a nipping part 38a and stopped, the paper P is fed further 10 to 15 mm by a paper charging roller 37 during a timelag, and a bend part P1 is formed between the paper charging roller 37 and a regist roller 36. After that, when the regist roller 38 is started being timed to the move of a toner image on sensitive material, the bend of the paper P is reduced. Before this bend is released, the paper charging roll 37 is further driven a minute time to feed the paper Pa a little more so as to prolong the bend reducing time. Thereby. the clashing speed of the paper P against a guide plate 82 is reduced and the clashing noise can be reduced.

Title: Processing for inserting/extracting tag bit for bit encode data processing system and data word
Inventor: RICHIYAADO GUREN AIKIRU
IPC: G06F12/08
Filed: 1990-11-29
Abstract: PURPOSE: To accelerate tag change by extracting respective tag bits inside the data word when the specified data word is provided in an intermediate data holding means, performing a tag operation for the specified data word and returning it to a memory array. CONSTITUTION: Relating to tag bit insertion, a pointer is read from an array 28, the tag bit is added, the pointer is returned to the array and thereafter, row and column address strobes are inactivated. For an extraction function, the pointer is read from the memory array 28, the tag bit is extracted and the tag bit is supplied through a data bus 36 to a processor 18. In such a manner, the circuit provided in a memory card 24 partially increases the speed of a tag bit extraction function and then increases the speed of a tag bit insertion function for the pointer inside the memory array 28. Thus, the tag change is accelerated.

Title: Threshold value processing circuit for picture signal
Inventor: ASANO FUMIO
IPC: H04N1/40
Filed: 1987-12-28
Abstract: PURPOSE:To give a proper threshold value in response to a picture signal by selecting any of a simple binarizing threshold value, an intermediate area processing threshold value and a threshold value of a threshold matrix based on a mode designation signal. CONSTITUTION:A simple binarization threshold value register 7-1 stores a threshold value used to apply binarization processing dividing the level into white or black level simply. An intermediate tone area processing threshold value register 7-2 stores a threshold value used to apply binarizing processing dividing levels into white, black and intermediate level (gray). Moreover, a threshold value matrix storage RAM 7-3 stores a threshold matrix used to applying binarizing processing with gradation such as a photographic picture. Then a multiplexer 7-4 selects a threshold value among the values corresponding to the mode designated in response to the picture status and the result is fed to a comparator 7-5.

Title: Erroneous connection detecting method of cable inside system
Inventor: NISHIMURA TADAO
IPC: H01R13/64
Filed: 1988-12-29
Abstract: PURPOSE:To make it possible to detect a connection error instantly by making a call for a connection head number from a cable master, replying from a cable slave when the calling number and its number data are coincident, and deciding an erroneous connection in the cable master. CONSTITUTION:There is a cable error connection error detector 2 in a cable master 1, and the cable master 1 outputs a connection head number data to check to a connection head number calling line 3 led out from the cable connection error detector 2. To the cable slaves 7, different connection head number data are allocated respectively, and only when the delivered connection head number data and the number of a cable slave 7 is coincident, a reply is returned through one of reply lines 9-11. Since the cable master 1 side knows which reply line is primarily for which connection head, the cable master 1 can decide whether a normal connection is made or not by comparing the calling connection head number and the replying line number to return the reply. Consequently, an error in the cable connection which used to be examined by a person can be detected instantly.
