Title: Detector of center position of recording disc
Inventor: NISHIO TAKASHI
IPC: G11B9/06
Filed: 1980-12-20
Abstract: PURPOSE:To detect the center position of a disc with good accuracy, by taking a pulse signal having a width in response to the width of an image corresponding to a recording track as an up/down command signal, and using an up/down counter counting a prescribed clock pulse. CONSTITUTION:Each image pickup output of image sensors 6-9 passes through image pickup signal processing circuits 11a-d and is converted into a binary level at AD converters 12a-d. This pulse signal has a pulse width in response to the width of image by an image pickup element corresponding to a recording track. A pulse signal output of the AD converters 12a-b with the image sensors 6, 7 checking the shift toward X is applied to an exclusive logical sum gate 13 and a gate signal having a difference of width of the pluse signals, i.e. a pulse width indicating the extent of shift toward the X direction is obtained. Since a  counter 15 shows the content of count in response to the width of gate pulse, a  signal corresponding to the extent of shift toward the X direction is obtained.  This is the same for the Y direction.

Title: Halftone image outputting method
Inventor: HATAKEYAMA FUMIHIRO
IPC: G03F3/10
Filed: 1994-07-07
Abstract: PURPOSE:To obtain halftone images in appropriate dot percentage corresponding to density value shown by image signals. CONSTITUTION:Image signals for a standard density are generated (step 1), and after converting the image signals into halftone signals with a halftone signal generating device (step 2), standard halftone images are outputted with a n output scanner (step 3). Then, the standard halftone images to be controlled are read (step 11) with read density higher than the recording density for that halftone dot, and binary signals are obtained therefrom (step 13) with a specified threshold applied. Then, dot percentage of the standard halftone images is measured (step 14) by counting the number of signals on one of the binary signals, and correction data are produced (step 16) by comparing the counted results with the value of standard density. Conversion characteristic for the halftone signal generating device is determined, based on the correction data.

Title: Metal member contact structure, image pick-up device and camera
Inventor: EZAWA AKIRA
IPC: G03B17/02
Filed: 1999-06-28
Abstract: PROBLEM TO BE SOLVED: To suppress the contact corrosion caused by bringing dissimilar metals different in corrosion potential into contact with each other. SOLUTION: An aluminum alloy fitting seat 4 is fixed to a magnesium alloy body 3 through an insert molding. A seat surface 4a is machined so that the dimension between a mount reference surface 35a and the seat surface 4a is L1 after a component such as a lens mount 35 is assembled with the body 3. A brass holder 23 to hold an image pick-up device 21 is fixed to the fitting seat 4 by screws 25. The corrosion potential of the magnesium alloy is lower than the corrosion potential of the brass, and the corrosion potential of the aluminum alloy is between that of the magnesium alloy and that of the brass. Thus, the differential corrosion potential can be reduced compared with that of the case when the brass holder 23 is directly fitted to the magnesium alloy body 3, and the contact corrosion can be suppressed.

Filed: 1985-08-19
Abstract: PURPOSE:To improve color tone reproducibility by a method wherein the size of openings in a light screening film that define the size of surfaces to receive incoming light signals is so designed as to be different dependent upon filter colors. CONSTITUTION:On a semiconductor substrate 1, with the intermediary of a film 3, an aluminum light screening film 4 is formed with openings for photodiodes 2. The openings are different in size dependent upon filter colors. That is, the opening for a picture element G corresponding to a green filter is designed to be larger than that for a picture element Ye corresponding to a yellow filter or a picture element Cy corresponding to a cyan blue filter. A process follows wherein a passivation film 5, smoothing layer 6, yellow layer 7, intermediate layer 8 (film for preventing blending of colors), second cyan blue layer 9, and an overcoat layer 10 are formed, which is accomplished in a conventional way. With the opening for the picture element G corresponding to the green filter formed to be larger than others, the quantity is increased of the light incident on the element G. This results in a more natural color tone because balance will be improved for example between the picture element G and the picture element Ye or Cy.

Title: Automatic setting device for sound recording level
Inventor: OKANO KIYOMI
IPC: H03G3/00
Filed: 1988-07-20
Abstract: PURPOSE:To perform sound recording within a reference sound recording level while a dynamic range is maintained by previously setting the level of whole input signals in corresponding to the stored peak values of input signals from various sources. CONSTITUTION:The output of a filter 5 is supplied to the A/D converter 6 of a system microcomputer 8 through a diode and resistance and further supplied to an arithmetic section 9. The section 9 calculates the changing quantity of the input signal level by detecting the peak value of the supplied signal level and supplies a calculated result to a control section 11. The section stores the calculated result (peak value) in a storing section 10. When sound recording is again performed from the same input source, the section 11 fetches the switching information of an attenuate switch circuit 2 or the calculated result of the arithmetic section corresponding to the input source and sets an appropriate sound recording level by controlling the circuit 2. Therefore, sound recording can be performed within a reference sound recording level while a dynamic range is maintained.
