A method for forming images on a display having a matrix of rows and columns of pixels is provided. Such method comprises the steps of: successively addressing the rows of pixels, each one of the rows of pixels being addressed for a predetermined addressing period of time. During each predetermined addressing period of time, a voltage level is applied to each one of the columns of pixels for a time duration in accordance with image intensity data and changing to a different voltage level during the remaining period of the addressing period of time. The voltage level changes only once during each predetermined addressing period of time. The anode of the display is coupled to a power supply adapted to couple either a relatively high voltage to the anode when such display is to operate in a relatively bright environment or a relatively low voltage when such display is to operate with relatively dim environment. The images are characterized by a gray scale level at each one of the pixels. The gray scale level is modified by a contrast term.

A stand-alone, interactive processor and display system for displaying, performing positioning, sizing, and performing supportive composition functions for newspaper advertising layout. Interactive work stations position copy, edit and correct text, adjust style and point sizes, to accomplish accurate composition functions. A Bit Image Memory digitally stores all displayed patterns directly to minimize the response time of the system to operator inputs. An arithmetic unit and character generator are disclosed which produce lines and characters which accurately represent the final copy. The arithmetic unit or processor includes a special purpose internally programmed arithmetic processor unit for controlling all display update operations in a newspaper advertising composition display system. Internal control is achieved through a Programmable Read-Only Memory in which all program operations are prestored. The arithmetic unit controls dot matrix character symbol representations in size and position.

A digital bit image memory system especially adapted for use in a newspaper-type composition and display system. At least one digital storage location is provided for each elemental display position. The memory system is formed with plural rows and columns of random access memory devices which are arranged and continually addressed to simultaneously refresh the display and maintain the stored data.

340728

A system for displaying, performing positioning, sizing, and performing supportive composition functions for newspaper advertising layout in which characters and symbols are displayed with a height and width closely approximating the height and width of the actual printed characters. Characters are displayed as rows and columns of dots. Preselected rows and columns are deleted or repeated to decrease or increase the size of a character from a standard fixed size. Interactive work stations position copy, edit and correct text, adjust style and point sizes, to accomplish accurate composition functions. A Bit Image Memory digitally stores all displayed patterns including the character dot patterns directly to minimize the response time of the system to operator inputs. An arithmetic unit is disclosed which produces lines which also accurately represent the final copy.
