Title: Focusing error signal detecting method
Inventor: MORITSUGU MASAHARU
IPC: G02B7/28
Filed: 1989-09-20
Abstract: PURPOSE:To reduce the crosstalk of a focusing error signal and a tracking error signal by computing the difference of the sum of the output of partition photodetectors being positioned at both ends of each of two partition detectors with an arithmetic means, and outputting it as the focusing error signal. CONSTITUTION:Assuming the values of the output signals of the partition photodetectors 25A-25C as A-C and that of the partition photodetectors 26A-26C as A'-C', a differential amplifier 31 outputs the focusing error signal with a value FES=(A+C)-(A'+C') in equation (2). Meanwhile, an adder 30 outputs the total sum (A+B+C+A'+B'+C') of the output signals as a reproducing information signal. Since a spot is made incident on only the partition photodetectors 25B, 26B in the center when focusing is obtained, the focusing error signal in equation (2) shows zero, and also, next equation SUM=(A+ C)+(A'+C') goes to zero when the focusing is obtained, which prevents the tracking error signal mixed (servo crosstalk) to the focusing error signal when the focusing is obtained.

Abstract: PROBLEM TO BE SOLVED: To improve the quality of an image by eliminating the adverse effect of an unevenness in the luminous intensity of a light emitting element, in a device for forming an image using plural light emitting elements. SOLUTION: An image processing device 30 loads in the memory the multivalued data di of an image signal 40 from an external source, then reads a weight factor based on the data relative to the previously measured luminescent intensity of each of LEDs of an LED array, and multiplies the multivalued data di by the weight factor of each of the corresponding LEDs to perform the binary processing of data relative to the calculation result by an error dispersion method. Further, the two-valued signal obtained by this binary processing is connected to an LED driver 20, and the light emitted by each of the LEDs of the LED array is switched ON/OFF to form a latent image on a latent image carrier moving in an orthogonal direction with the LED array 10.

Title: Image output amplifier
Inventor: OKAMURA YUKIMICHI
IPC: H04N5/14
Filed: 1984-11-20
Abstract: PURPOSE:To protect an output transistor by detecting the excessive voltage of an input signal to an image output amplifier and controlling consumed power of output transistor of the image output amplifier during the input period of the excessive voltage. CONSTITUTION:When the input signal inputted in an input terminal indicates an excessive voltage, the voltage is compared with the voltage level VTH set in the input terminal of a comparator 4. As the result, the comparator 4 outputs a negative pulse signal in the period exceeding VTH. The pulse signal is inputted in an integrating circuit 5, smoothed, and controls a stabilized electric source. The stabilized electric source is composed of an error amplifier 3 and an output transistor Tr Q4 of the voltage source to provide the voltage VC to a load resistance RL of Tr Q1 and a collector of Tr Q2. In such a case, when the input signal indicates an excessive voltage level, the voltage VC is decreased to regulate the consumption of power of the output transistor. In case that unusual period of image signal lasts decrease of VC grows bigger to make a sufficient protection of output transistor.

Abstract: PURPOSE:To obtain an excellent copy of even an original where a halftone image and a binary image are both present and to facilitate the erasure of an optional area on the original by discriminating between the halftone image and binary image with respect to each area on the original and switching both automatically. CONSTITUTION:A signal outputted to a recording means is switched among a signal after halftone processing, a simply binary coded signal, and a specific- level signal automatically. The area decision means is equipped with the 1st decision means and the 2nd decision means. The 1st decision means decides the level of the output electric signal of an image read means with the 1st threshold level and decides whether the original image contains halftone information or not on the basis of the binary-coded signal and the 2nd decision means decides the level of the output electric signal of the image read means with the 2nd threshold level and decides whether the original image contains the halftone information or not on the basis of the binary-coded signal. When the specific-level signal is selected, respective picture elements of a recording image are recording picture elements or nonrecording picture elements irrelevantly to the original image.
