A vector generator for producing graphic images composed of line segments, having a discrete frequency multiplier 60 which comprises initializing means, stopping means and means for punctuating the drawing of the segments; input means for the M and N components of the segment, and a writing pointer 50 in an image memory 20. The invention may be used in graphic consoles and X, Y-plotters.

The present invention relates to apparatus for printing graphic forms simultaneously with information data. A graphic forms master is mounted on a relatively small forms drum which is coupled to rotate simultaneously with a photo-sensitive print drum. Light is reflected from the graphic forms master to a light sensitive transducer from where electrical signals, representing the graphics form, are transmitted to a signals merging circuit. Information data signals are also transmitted to the signa...

A graphic reproduction guide for the enlargement of realistic images from a relatively small die cut planar element comprised of sequentially positionable registrations and distinct groups of delineation features sequentially applicable to correspondingly identified registrated positions for the application of graphic lines and/or points to cover a surface in multiple areas larger than the device.

An electronic graphic system 1 processes image data defining color values of a multiplicity of pixels that together form an image. The system 1 comprises a processing unit 14 in which image data from an image store 2 is processed with other image data from a store 9. The processing is effected on a pixel-by-pixel basis depending on control data in a control store 15 and on a predetermined gamma factor defining a relationship between color values and corresponding light values. The processing uni...

Graphic data generated by an application program implementing CAD, for example, are classified into groups according to their attributes and stored into memory. When a display request is issued, the graphic data are output onto a display device, one group at a time, thereby reducing the amount of attribute judging and attribute changing processing and thus achieving an increase in the display processing speed.

A photothermographic or thermographic material comprising a support having provided thereon or thereabove at least one image forming layer having its thermal expansion coefficient in the range of 1.0 to 1.5 and having provided on or above said at least one image forming layer a layer which has its thermal expansion coefficient of at least 0.9 and lower than 1.0 and comprises at least one kind of polymer latex having a glass transition temperature of not higher than a heat development temperature...

A graphic forms overlay apparatus to be used with non-impact printers requiring the use of a movable light sensitive medium such as laser printers is disclosed. Laser printers use a sweeping laser beam and a movable light sensitive medium to image data from a data processing source for printing. A graphic forms pattern is overlayed on the data imaged on the light sensitive medium for simultaneous printing of the data and pattern. To accomplish this a negative of the pattern is mounted on a hollo...

A method for generating and coding graphic images for transmission to hand-held or mobile devices uses an object-component technique wherein images are composed from a limited set of component types, particularly points and polygons. Images are encoded as a list of objects to be drawn, with each object specified by a command word (FIG. 3) followed by one or more coordinate words (FIG. 4) locating that object in a fixed coordinate image field. The command word indicates the object outline colour ...

A graphic art correction stylus includes a cylindrical body which houses a motor and a battery for rotating a fluted stylus secured to one end of the cylindrical body, and at the opposite end of the cylinder is a fixed stylus.

A pushbutton tunable radio having an integral audio graphic equalizer is disclosed. During a tuning mode of operation for the radio actuation of any of five presettable pushbuttons results in the selection of a predetermined radio channel frequency within the AM or FM band, and a five digit display is provided indicating the selected channel frequency. During an equalizer mode of operation caused by actuation an equalizer mode selecting pushbutton, the radio remains tuned to the previously selec...
