摘要： PURPOSE:To obtain a converted picture without missing of input picture information by revising a picture element number being an object of the arithmetic means operating processing properly depending on the reduction rate. CONSTITUTION:An output selection command signal inputted from an input terminal 10 is counted by an address counter 32 and used as an address data for a picture memory 34. On the other hand, an output selection command signal is subjected to timing correction (operation time compensation of the address counter 32) by a delay circuit 33 and allows an output, the inverse of OQi of a selection circuit 9 to store the picture memory 34 by using the result of timing correction as a write pulse. Thus, a reduced picture is stored in the picture memory 34 and the mis-receiving of input picture information is eliminated by adjusting the picture element number being an object of the arithmetic mean operation in response to the reduction rate thereby reproducing the continuity of the input picture in converting the picture.

摘要： PURPOSE:To facilitate the management of a picture signal data by using an output signal of an offset picture count means counting picture element number in the unit of words of a read picture signal data so as to apply parallel picture signal transfer at each word unit of a serial read picture signal. CONSTITUTION:When a picture reader starts reading a picture, a picture signal enable signal 21 is set as a line synchronizing signal 20 is set and a picture signal count enable signal 24 is also set. In this case, as soon as a picture signal clock 16 inputted simultaneously with a serial picture signal 15 is inputted to a serial/parallel converter 5, a gate circuit 14 controlled by a read picture element end signal 23 and a picture signal count enable signal 24 is opened. Thus, the operation of a read picture element counter 8 and the operation of an offset counter 10 by an input picture signal clock controlled by a delay circuit 9 are started. The delay circuit 9 is provided to ensure the timing operation of the output picture signal data of the serial/parallel converter 5 onto a latch 6.

摘要： PURPOSE:To automatically obtain density level correction with high precision by controlling the input picture signal at constant amplitude by making shading correction to manuscript reading picture signal and controlling variable amplifier according to the maximum white density and maximum black density. CONSTITUTION:When reading the input manuscript, selection switch 22 is connected to (b) side, and correction factor is read from white reference memory 17 of correction ROM 18. This correction data is connected to variable amplifier 12 for shading correction through a D/A converter 19, and the shading correction is made between picture signal 11' of input manuscript which is amplified by pre-amplifier 11. Furthermore, by setting gain and offset values corresponding to the maximum white density and maximum black density at terminals 23, 24 when the reading of white reference is finished, D/A converters 20, 21 control the output voltage level of variable amplifier 13 and amplifier 14. Thus, even when the input picture signal 11' fluctuates according to the change of density of manuscript, it is possible to control up to the range of input voltage of an A/D converter 15.

摘要： PURPOSE: To attain an artificial half-tone display which is free from deterioration of the picture quality due to the deterioration of image resolution of binary pictures, by applying the picture processing repetitively to the entire areas of the 1st and 2nd picture signal memory means while shifting the 1st and 2nd scan windows by an amount equivalent to the prescribed picture elements.
CONSTITUTION: A redistribution circuit 29 produces the conversion data from the sum total S obtained from a data addition circuit 25 and writes the conversion data successively to the address of a picture data memory 21 designated by an address control circuit 22 via a gate circuit 20. An error correction arithmetic circuit 26 selects a picture signal level P
1 ST, i.e., the finally data converted value within a scan window out of the conversion data of the circuit 29 based on the information on the address and the timing given from a sequencing circuit 28. Then the level P
1 ST is compared with a binary coding level V obtained from a binary coding circuit 23 to obtain the value P
2 ND of O or C, and the value P
1 ST-P
2 ND is given as an error correction amount E of the next scan window. Furthermore the result of comparison between the amount E and the level V is informed to an additional data addition circuit 27. Such a procedure is repeated to process picture signals.

摘要： PURPOSE:To compare and analize correctly the time relation between phenomena produced at a CPU and a device to be controlled by comparing the program information fed from the CPU and a reference signal, and stopping the actuation of the CPU in response to the result of said comparison. CONSTITUTION:The stopping conditions of a program are set via a keyboard 3-M, and a reference signal generator 4-M is actuated. Then the generator 4-M sends a reference signal to a comparator 5-M. The comparator 5-M compares the program information fed from a CPU1 with the reference signal and outputs a signal of value 1 if the stoppage of actuation is desired for the CPU1. Then a signal changeover switch 9-M of an execution stop signal generator 8 is closed simultaneously with the conditions of a switch 13-M is set. Thus a signal of value ''1'', if outputted from the comparator 5-M, is sent to an FF circuit 11. Then the circuit 11 transmits an execution stop signal to the CPU1 to stop the actuation of the CPU1. In such a way, the program debug is performed for the CPU1.

摘要： PURPOSE:To select easily any of an adopted matrix and its transposed matrix by providing an address changeover circuit and a switch in the recording of a black-and-white picture using a dither method. CONSTITUTION:A picture signal 10 transmitted from a picture reading section 1 is outputted as a quantized picture signal 12 via a buffer 11. A row counter 3, a column counter 6 count respectively a clock signal 2 and a main scanning synchronizing signal 5 and outputs a row address signal 4 and a column address signal 7. when a switch SW18 is turned off, an address switching circuit 17 converts the signal 7 to a higher address signal 19 and the signal 4 into a lower address signal 20, and when the SW18 is turned on, the signal 4 is switched to the signal 19 and the signal 7 is to the signal 20. A storage device 8 is addressed by the signals 19, 20 and when the SW18 is turned off, the signals correspond to integral numbers m, n. An element dmn of the matrix D of k-row and k-column is taken as a threshold value 9, and when the SW18 is turned on, the element dnm of a transposed matrix D is taken as a threshold value 9 and outputted to a comparator 13. The comparator 13 records (16) the result of comparison between the threshold value 9 and the signal 12.

摘要： PURPOSE:To reduce considerably the variation of an output signal due to the uniformity of a recording scanning line by providing a deciding device for the side of a readout scanning window which decides the size of the readout scanning window to a natural number multiple of the size of a recording scanning window. CONSTITUTION:When an integer (h) which is larger than zero is inputted to an input part 18 for the size of the recording scanning window, the gate 22 of a deciding circuit 19 for the size of the readout scanning window sends out a control signal 24 to a data line switch 23, an error is sent out to a driving part 13 for the readout scanning window as data that the data of a data buffer 20 is controlled by a data line switch 23. When the data of the buffer 20 is inputted, this driving part 13 controls the window opening diameter of the readout scanning window 14 so that a readout signal is obtained by averaging light and shade stripes synchronizing with the scanning line pitch of an original image as shown by a dotted line l3.

摘要： PURPOSE:To improve half-tones by storing an input picture signal in two memories after A/D conversion, using one for sequencing and the other for data conversion by reallocation, and correcting and then outputting data in order. CONSTITUTION:An analog signal from an input terminal 16 is A/D-converted 17 and inputted to image data storage devices 19 and 21 through gate circuits 18 and 20. A storage device 19 is used for sequencing, and a storage device 21 is used for data conversion by reallocation. An additional data adding circuit 27 reduce each data in a scanning frame from the storage device 21 to a fraction, sums up and corrects data obtained by an error correcting arithmetic circuit 26, data adding circuit 25, and reallocating circuit 29, and carries out sequencing 28 and address control 22 to send the resulting data to the gate circuits 18 and 20. The output of the sequencing circuit 28 is fed back to the error correcting circuit 26 and reallocating circuit 29. The gate circuit 20 stores the conversion output of the reallocating circuit 29 in the storage device 21, and it is binary-coded 23 and outputted 24. Thus, half-tones are improved without spoiling the resolution.
