Patent Number Title Of Patent Date Issued
6184929 Solid state imaging device and image read apparatus with polygonal photosensitive pixels February 6, 2001
A solid state imaging device comprising:a plurality of photosensitive pixels for scanning an optical image signal falling thereon and converting the same photoelectrically which are arranged in parallel to one another in a main scan direction,wherein the photosensitive pixels are respectivel
5757520 Color linear image sensor and an image processing system May 26, 1998
A color linear image sensor includes a sensor pixel linear array with a plural number of color filters laid and bonded thereover, a readout circuit and an output processing circuit. The sensor pixel linear array consists of repeat patterns of color pixels linearly arrayed in a preset
5325210 Shading data accepting system in image readers June 28, 1994
Because of using as a light source a halogen lamp which is well stabilized in terms of both the quantity of light and the spectral ratio, it is unnecessary to read shading data whenever the reading of an image is initiated. The shading data can be read with a certain margin at the end
5204755 Radiator system in image recording apparatus April 20, 1993
An image recording apparatus comprising a line sensor for reading image data, a driver for outputting the image data read by the line sensor wherein the driver comprises an integrated circuit mounted on a circuit board, and a radiator system for dissipating heat generated by the driver,
5189528 Image reading apparatus February 23, 1993
An image reading apparatus with a plurality of line sensors comprises a reference level adjusting circuit for adjusting a level of a dark output outputted from one of the line sensors to a reference level, and a level difference adjusting circuit for progressively adjusting to a minimum
5177621 Self-diagnostic system for image reading equipment January 5, 1993
A self-diagnostic system for image reading equipment having an imaging unit and at least one circuit board, including a pattern generator, which generates a prescribed pattern signal, disposed at the input end and/or the output end of the circuit board. According to this system, a source
5157518 Image data control system for image reading equipment October 20, 1992
An image data control system for use in an image reading equipment, in which analog signals output from a line sensor, which represent the amounts of light reflected from an original sheet are converted into digital signals by analog/digital conversion, and then the digital signals a
5148296 Original document reading apparatus September 15, 1992
An original document recording apparatus having a plurality of line sensors arranged in a uniformly staggered pattern. Each line sensor has a built-in analog memory, which stores the image and outputs the image according to a delay value. The built-in analog memory is controlled by two k
5140445 Imaging reading apparatus having a preheating system August 18, 1992
An image sensor is operable in a read state, a rest state, and a stand-by state. Control signal generating means generate a control signal. The control signal has a first constant preset level during the read state, a second preset level during the rest state, and alternates between the
5059860 Illuminating light source for color image recording device October 22, 1991
An illuminating light source for a color image recording device comprises a glass tube having a predetermined diameter, a reflecting film coated on an inner wall of the glass tube excepting a part thereof by coating, a fluorescent film formed on the reflecting film coated on the glass tu
4783836 Information reading apparatus November 8, 1988
In an information reading apparatus in which picture image data of manuscript read with a manuscript reader is converted into a digital signal including picture image data or shading correction reference density data of the manuscript, and the digital signal is converted into a logar
