摘要： PURPOSE:To attain the compatibility of multigradation reproducing and high resolution to make pseudo gradation reproducing by determining the black picture element density and the black picture element arrangement in accordance with the density and the density variance of an original picture. CONSTITUTION:After a binarization correcting quantity Ea is cleared to zero to perform initialization, an original picture signal is read into a storage means 2 for redistribution and a storage means 4 for ranking, and the picture signal level of 4 picture elements is decided, and the binarization error Ea is cleared to zero if said level is higher than a certain high level or lower than a certain low level. A sum S of the picture signal level addition value of picture elements R00-R11 in a scanning window Wr of the means 2 and the quantity Ea is calculated to calculate a distribution number N and a residual A of a maximum value C of the picture signal level satisfying S=CXN+A. Picture elements O00-O11 in a scanning window W0 of the means 4 are ranked in the order of picture signal level by a ranking means 5. In accordance with this picture element order, the maximum value C of N-number of picture element signal levels, the residual A, and a picture element O and defined as the picture element signal level of picture elements R00-R11 in the window Wr.

摘要： PURPOSE:To obtain visually a good picture without deteriorating a mesh point photograph and making round a part of a corner a character line picture by detecting a black and white border area of a straight line part of the character and line picture parallel to a picture scanning and executing a partial smoothing processing. CONSTITUTION:At a scanning window of 5X5 in a data memory circuit 6, the stored binary data are rescanned, and a central picture element in the scanning window is rewritten by a setting/resetting signal 22 and further, an isolated picture element in the scanning window is also rewritten by an isolated picture elementremoving signal. Border column detecting circuits 9 or 11 in the main scanning and sub-scanning directions decide that out of main scanning data sandwiching the scanning window, one row of either of other side two columns is wholly 0 (or 1), one row of either of opposite side two rows is wholly 1 (or 0) and then, the main scanning line data including a central picture element are border rows, and outputs 1 to signal lines 10 or 12. A weighting adding value is added to a binary processing, and further, an isolated picture element located in the backward direction of the scanning window which occurs newly by resetting an isolated picture element and a central picture element located in the forward direction of the scanning window.

摘要： PURPOSE: To read an original picture with high accuracy at an arbitrary scan line density by providing a reading means for reading picture information, 1st and 2nd sampling means and an arithmetic means for carrying out arithmetic mean of image signals of respective reference read picture elements with respect to the sub-scan direction from the output of the 2nd sampling means.
CONSTITUTION: The output of a digital signals correcting device 8 is converted into an analog signal by a D/A converter 10. A image signal applied to an A/D converter 11 is an analog picture signal which has been obtained by the photoelectric transfer with use of one-dimensional solid-state image sensor 4 and is subjected to the corrections such as shooting correction or gradation one. This analog picture signal is again converted into a digital signal by the A/D converter 11. The frequency of the sampling pulse of an A/D converter 7 is decided by the number of picture elements of said sensor 4 and the reading time of one line. However, the frequency of the sampling pulse of the A/D converter 11 is so constituted to be freely set, and the number of read-out picture elements of one line of the frequency can be modified.

摘要： PURPOSE:To improve the gradation characteristic by dividing the total error correcting amount, using one as the error correcting amount, adding it when the total sum is obtained, using the rests as a divided error correcting amount, adding it to a value after data conversion and replacing it. CONSTITUTION:The final data converting value of the scanning window 6 is taken as P1ST, a difference with a value P2ND (0 or C) discriminating the threshold value and the result is taken as the error correction total amount ES. The total amount is divided, one is used as an error correction amount E, added when the total sum S at the next scanning window 6 is obtained and the rests are added to the value of D''m,n-1 after data conversion and replaced. Thus, the error correcting amount E corrects the total sum S used for the next processing in the main scanning direction and the divided error correcting amount Ed corrects the total sum S used for the next processing in the sub scanning direction. Thus, the gradation characteristic in the main and sub scanning direction is improved.

摘要： PURPOSE:To suppress periodic pattern generation of a reproduced picture by distributing again a converting data in the order of the size of an original picture data. CONSTITUTION:In taking a scanning window as 2X2 picture element, as the scanning window 6 is moved by one picture element each in the main scanning direction and the sub scanning direction, a picture element Dmn in the scanning window 6 is subject to 4 times data conversion. In executing data conversion as to all data of an original picture, when the data value is small, number of 0s is large and when the data value is large, the number of C=Dmax is large and the data is being converted in proportion to the data value of the original picture data. Thus, in using a binary-coded data to the value subject to data conversion, the data of pseudo intermediate display is obtained.

摘要： PURPOSE:To obtain a picture alike a sand surface by changing the 2nd random signal in the timing represented by a numeral in a sand surface particle distribution table selected sequentially in response to the value of the 1st random signal and binary-coding an input picture signal through the use of the value of the 2nd random signal as a threshold value arranged two-dimentionally on a picture screen. CONSTITUTION:The content of a subtraction circuit 33 is decremented by 1 at each clock pulse transmitted via a gate circuit 1, while the content of a random signal generating circuit 31 is updated. Then a storage device 32 outputs a numeral of the sand surface particle distrubution table according to the address respresented by the content of the random signal generating circuit 31. Further, when the content of the subtraction circuit 33 reaches 0 as the result of subtraction , a random signal generating circuit 34 is commanded to be updatd for the content. Further, the output data of the storage device 32 is fetched by the subtraction circuit 2 at the same time. Then the content of the random signal generating circuit 34 is outputted to latch circuits 18, 21 as the threshold value signal to binary-code the picture signal.

摘要： PURPOSE:To read automatically and constinuously a mesh point ROM and also to replace the mesh point ROM during the operation by counting up automatically an address by +1 via a data register and also providing an ROM conduction control means. CONSTITUTION:When a conduction clock is applied from an address decoder 13 in response to input information, a data latch in reset state is turned on, a relay 30 is energized, a power is applied to a mesh point ROM 28 and also the state is informed by the lighting of an LED31. On the other hand, a decoder 13 loads an address corresponding to address counter 22-24 via an address register 131 in response to the input address to allow the ROM28 to read the address. Then the counters 22-24 are incremented by +1 via a data register 132 of the decoder 13 controlling the read data to read continuously the ROM automatically. Further, a data latch 21 is reset via the decoder 13 and the extinguishment of LED31 is confirmed, then the mesh point ROM is replaced easily while the power is being applied.
