Abstract: An apparatus and method for adding information to image data of a multicolor image and a monochromatic image includes the performing of a dispersion conversion on the spectrum of additional information to be added to the image data by multiplying a code sequence of a PN sequence generator by the additional data which is inputted from an input terminal and converted into serial data in a P/S converter. At this time, the data sequence transmitted from an image signal processor to a printer engine 107 is converted by a scan converter to correspond to the spatial axis for dispersion. The converted data sequence is added to the output from an adder by another adder 110, and reconverted to the original scan by a scan inverter.

Abstract: The present invention provides an apparatus and method for producing series of high resolution color composite images. The digital camera has an optical assembly that directs visual images to a high resolution monochrome sensor and a lower resolution color sensor. These two sensors, which produce a succession of frames at the same rate, are encrypted with a frame number and time code and are stored in a frame buffer. The contents of the frame buffer can be transferred to a mass storage device, or a color rendering processor that produces a composite image from the monochrome frames and color frames. During the processing of the composite image, the monochrome grayscale value becomes the composite frame grayscale value, the color frame hue value becomes the composite frame hue value, and the color frame saturation value becomes the composite frame saturation value.

Abstract: A facsimile apparatus which enables the printer section and document original reading section thereof to be used as a printer and image reader, respectively, for a personal computer. To use the reading section for reading a document original as the image reader for the personal computer, the operation mode of the facsimile apparatus is switched from an ordinary operation mode to a PC-FAX mode. When a document original is read by the reading section in the PC-FAX mode, the facsimile apparatus behaves as if it received a call-in of facsimile correspondence, and sends image data to the personal computer. Further, by operating an operation section, a printer function call number is registered for an external input printing function which enables information input to an interface to be printed out. When a call-out command designating a phone number is sent to the facsimile apparatus from the personal computer, a control section judges if the phone number agrees with the printer function call number.

Abstract: Address information generated and output by an address converter for each pixel of input image data in accordance with the phase based on the position of the pixel to be coded is stored in an address storage divided into address groups which are periodically referred to. Information indicative of the occurrence probability of the pixel to be coded and phase information of the pixel are selectively output from the address storage, and an arithmetic coding is performed for the output. During the processing, update data is written in to one group while a read-out is being performed for the other group. A template is constituted by excluding a pixel which predeses one pixel, and a prediction state in each phase is divided into two parts. The template output is applied to both of the divided storage devices, and read actions are independently performed.

Abstract: Terminals, printing apparatus, and digital copying machines are connected to one network N. A document managing portion of the printing apparatus stores document data received through the network N to a document data storing portion, and generates managing data of document data so as to be stored in a document managing table. When an error processing portion detects the occurrence of an error with reference to a table during the printing of document data, an error processing portion determines the other printing apparatus for a substitutive printing with reference to various kinds of tables, and transmits document data. A report sheet issuing portion generates a report sheet image showing a name of a substitutive printing apparatus, a current state of the apparatus having an error, measures to remove the error, etc., and a printing portion prints the report sheet image.

Abstract: A compact medium scanner (100) scans a surface (132) of a medium (134) with a beam of light (106). A medium transport mechanism (202, 206) advances the surface along a medium transport path through a scanning station. A light source (104) produces a collimated beam of light (106) that impinges upon a mirror plate (112) of a micromachined torsional scanner (108). A pair of coaxially aligned torsion bars (304) support the mirror plate (112) within the torsional scanner (108). A mirror-surface drive means (306, 312) rotates the mirror plate (112) about the torsion bars (304). A single reciprocation of the mirror plate (112) by the drive means (306, 312) deflects the beam of light (106) over a fan-shaped region having a virtually fixed vertex (128) on the mirror plate (112). Scanner optics (116, 122) direct the fan-shaped region beam of light (106) onto the surface (132) of the medium (134) then present in the scanning station to thereby scan across the medium (134) with the beam of light (106).
