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 obtain a sharp picture signal by a simple optical system by quantizing and storing a read picture in a line memory, and reading and delaying the picture specifically and then performing contour emphasizing operation. CONSTITUTION:An original 15 set around a drum 16 is irradiated with light from a light source 22 and its reflected light is converged to form an image on the surface of an aperture 25. Light passed through the aperture 25 is converted by a photoelectric converter 26 into an electric signal, which is amplified 27 and then applied to an A/D converter 28. A sampling pulse generator 29, on the other hand, is initialized by a phase signal (g) on every turn of the drum 16 to generate sampling pulses (h) of frequency corresponding to scanning density. The converter 28 converts the input signal from analog to digital by the pulses (h) to supply an output signal to a memory part 30. The contents of the memory part 30 are read out in specific order and applied to an arithmetic part 31. The arithmetic part 31 delays the picture signal specifically and then processes the signal by using a contour emphasis constant (n) set on a constant setting panel 32 as a parameter to generate output data O and an output clock P.

摘要： PURPOSE:To obtain a picture signal without a shadow signal by receiving a reflected light from an original scanned by light from a light source at plural photodetectors arranged in a different angle, obtaining a sum/difference signal of plural signals and subtracting an absolute value of the difference signal from the sum signal. CONSTITUTION:When an original plate 10 mounting a sticked original on which an original 7 is sticked at the upper surface is moved from the right to the left by a driver, a reflected light irradiated from the light source 11 passes through a photoelectric converter 12 and an A/D converter 16, and a shadow signal is obtained from P5 and a black ground signal is obtained from P6 to P7 in an output signal A2. On the other hand, a black ground signal is obtained from P6 to P7 in an output signal A3 of an A/D converter 17 and a shadow signal is obtained from P8. The shadow signal only appears in an output A4 of a subtractor 19 subtracting the signal A3 from the signal A2, the signal is brought into a unipolarity A6 by an absolute value generator 20 and since the black signal and all the shadow signals appear at an output A7 of an adder 18, the picture equality is improved without shadow by subtracting the signal A5 from the signal A6 at a subtractor 21.

摘要： PURPOSE:To eliminate the noises of only a region that is designated to an input original with reduced storage capacity, by designating an optional region on the original by means of a coordinate input device and eliminating the noises within the designated region. CONSTITUTION:The pictures of an original 12 on a coordinate input device 11 are formed on slits 15 and 16 of different diameters and then read after main and secondary scans carried out by these slits. The beams transmitted through the slits 15 and 16 undergo photoelectric conversions 17 and 18, respectively, and high-frequency noises are reduced via LPF19 and 20. At the same time, the amplitude of each output signal is normalized to have the same level as full- white and full-black parts of the original 12. Before this scan of pictures, a region where a reduction of pictures is desired is designated by a curve 30. This curve 30 is fetched by an electronic computer 27 and stored as a reduced coordinate data with the synchronizing signal S of an oscillator 23. Then an FF22 is actuated with the output of coincidence 26 of comparison between the latch 25 of the contents of stored reduced coordinate data and the clock count value 24. An analog switch 21 is switched by outputs Q and Q' of the FF22, and the output of the LPF19 or LPF20 is selected.
