Abstract:
There is disclosed an apparatus for image reading or processing, that can precisely identify a particular pattern, such as of banknotes or securities faithful copying of which is to be prohibited. The apparatus is provided with a detecting unit for detecting positional information of an original image, and a discriminating unit for extracting the pattern data of a certain part of the original image and discriminating whether the original image is the predetermined image, based on the similarity between the pattern data and the predetermined pattern.
Abstract:
A plurality of subsystems having diverse individual functions can be connected to an image forming apparatus. Each of the subsystems is made up of, for example, plural kinds of units which are different in performance from each other. Each of the units has inherent information related to the performance, and decides the operation specification of the entire image forming apparatus according to the combination of those units.
Abstract:
The invention provides an information processing apparatus in which print data is inputted, whether or not authentication information has been added to the print data is discriminated, and an output destination of the print data is controlled on the basis of the discrimination result, thereby making it possible to prevent the print data from being sent to an image output apparatus of a low security level.
Abstract:
A vibration control device of a vibration type motor stops motor driving when the actual driving speed, does not come close to a target speed though the frequency of a driving periodic signal is feedback-controlled to the target speed, to prevent an error when the driving circuit fails.
Abstract:
An image processing apparatus includes a first detection unit for detecting an edge of an input image on the basis of an input image signal, a second detection unit for detecting a screen portion of the input image on the basis of the input image signal, a processing unit for executing processing of the input image signal according to detection results of the first and second detection units, and a setting unit for setting detection modes of the first and second detection units.

Abstract:
An image formation apparatus which records an image on a recording medium is provided. The apparatus has a recording element array head on which plural recording chips are arranged, plural recording elements being arrayed on the recording chip, a reference clock generation unit for generating a reference clock, a main scan sync signal generation unit for generating a main scan sync signal by dividing the reference clock into 2n1 (n1: positive number) parts, an input unit for raster inputting image data for one line in synchronism with the main scan sync signal, a drive clock generation unit for generating a drive clock by dividing the reference clock into 2n2 (n2: positive number) parts and a drive unit for driving the recording chips in synchronism with the drive clock.
Abstract:
An image processing apparatus and method includes a device for judging the degree of color or lack of color of an input color image signal, judging dot areas in input color image signal and controlling a spacial filter or a density conversion device for processing the input image signal according to a judgment by the first and second judging results, the spacial filter or the density conversion device being controlled according to the judgment by the first and second judging results, wherein the image processing also includes the ability to independently set sharpness of each of a plurality of color component signals.
Abstract:
A system for displaying images is provided having a reading device for reading an image and generating an image signal, a forming device for forming an image based on the image signal generated by the reading device on a recording medium, a display device for displaying the image to be formed by the image forming device, and an input device for entering an image signal from an external equipment, wherein image formation by the image forming device and display by the display device are made possible based on the image signal entered by the input device.
