Abstract:
A device for expanding the effective width Of an image forming surface, such as the face of a cathode ray tube, on which characters are formed in proper succession to make up lines of composition includes a carriage supporting photographic material, which is in optical alignment with the image forming surface, for permanently recording the images thus formed on the display surface, the carriage being movable from a first position, where a large portion of the photographic material is exposed to the image formed on the tube, to a second position where the remainder of the photographic material is placed within the field of view of the image forming surface.
Abstract:
Coded record manufacture and apparatus suitable for storing digital representations of graphical images, such as characters, are disclosed herein for use in subsequent reproduction of the images, as on the face of a cathode-ray tube. Images or characters are scanned to obtain electrical signals indicative of the features thereof and the signals are recorded as digital representations.
Abstract:
A phototypesetting system wherein characters may be displayed on a cathode-ray tube includes a character-positioning means for locating accurately each character horizontally on the face of the tube in response to the status of an accumulator means. The character-positioning means includes an output circuit means having a substantially linear response to the status of the accumulator to provide a substantial portion of the characterpositioning signal, and a compensating means, also responsive to the status of the accumulator means, to supply only that portion of the character-positioning signal which is necessary to compensate for nonlinearity in the characteristics of the cathode-ray tube so that the characters of consistent size may be accurately positioned regardless of the horizontal position of the characters relative to the face of the tube.
Abstract:
A PHOTOTYPESETTING METHOD AND APPARATUS UTILIZING A CATHODE-RAY TUBE TO DISPLAY CHARACTERS ONE AT A TIME ON THE FACE THEREOF FOR PHOTOGRAPHIC RECORDATION EMPLOYS AN OPTICAL CHARACTER DISC HAVING FORMED THEREON A FONT OF CHARACTERS IN THE FORM OF A PLURALITY OF BINARY BITS REPRESENTED BY OPTICAL MARKS. THE CHARACTER DISC IS USED IN CONJUNCTION WITH CONTROL SIGNALS FROM A CONTROL RECORD TO FORM CHARACTERS OF VARIOUS SIZES ON THE CATHODE-RAY TUBE. A BUFFER MEMORY CIRCUIT ACCEPTS INFORMATION IN PARALLEL FORM FROM THE CONTROL RECORD, CONVERTS THIS INFORMATION INTO SERIAL FORM, STORES THIS INFORMATION UNTIL IT CAN BE USED BY THE TYPSETTING SYSTEM, AND THEN RECONVERTS IT TO PARALLEL FORM FOR UTILIZATION BY A DECODER CIR-
CUIT WHICH PROVIDES THE SIGNALS NECESSARY FOR THE CONTROL FOR VARIOUS TYPESETTING OPERATIONS AND FOR THE SELECTION OF THE CHARACTERS TO BE DISPLAYED. ELECTRONIC CIRCUITS COMPENSATE FOR THE NONLINEARITIES IN THE CATHODE-RAY TUBE TO PERMIT CHARACTERS TO BE FORMED ON THE FACE THEREOF IN PROPERLY SPACED RELATION AND WITHOUT DISTORTION REGARDLESS OF THEIR POSITION ON THE TUBE. OTHER ELECTRONIC CIRCUITS ARE EMPLOYED FOR THE GENERATION OF THE CHARACTERS AS CONTROLLED BY THE BINARY BITS ON THE CHARACTER DISC, FOR CONTROL OVER THE CATHODERAY TUBE INTENSITY, AND FOR LEADING OF THE PHOTOGRAPHIC RECORDING MEDIUM.
Abstract:
Composing method and apparatus for publications such as newspapers in which copy from various sources is entered into a computer in coded form for use in controlling a phototypesetter to prepare a page copy. Certain copy including artwork which may be halftone or continuous tone is scanned to provide the numerical data necessary for controlling the phototypesetter while text material is first edited on an editing terminal and then stored with or without phototypesetting instructions in the computer. Each item to be included in the publication is identified by a heading and a layout department instructs the computer as to where the items are to appear. For this purpose the layout department has a layout terminal for displaying page areas with previously assigned sections outlined and identified and for entering coordinates of newly assigned sections into the computer. The terminal can display magnified portions of the page area. In reproducing continuous-tone copy, dot characters are stored in a character memory and used to provide different halftone screen sizes.
