`
`CLASS 345, COMPUTER GRAPHICS PROCESS-
`ING AND SELECTIVE VISUAL DISPLAY
`SYSTEMS
`
`SECTION I - CLASS DEFINITION
`
`This class provides for processes and apparatus for
`selective electrical control of two or more light-generat-
`ing or light-controlling display elements* in accordance
`with a received or stored image data signal. The image
`data includes character, graphical information or display
`attribute data. The image data may include, for example,
`information data from a peripheral input device, from
`the reception of a television signal, from the recognition
`of image data, or from the generation or creation of
`image data by a computer.
`
`This class also provides for digital data processing sys-
`tems or methods for data processing for visual presenta-
`tion, wherein the processing of data includes the
`creation or manipulation of graphic objects (e.g., artifi-
`cial images), or text.
`
`SCOPE OF THE CLASS
`
`(1) Note. This class includes a display control-
`ler* for accessing image data. The display
`control
`includes, for example, control
`between a display memory and the display
`elements*. The display control may be per-
`formed by a processor, wherein enhance-
`ments for a previously created and stored
`image are provided. Examples of such dis-
`play control
`include display memory
`addressing, display screen energizing, and
`received image data control in response to
`input signals applied to the display control
`to provide an enhanced image for display.
`A specific display system* in combination
`with a data processor or computer is classi-
`fied herein.
`
`(2) Note. The display elements* of this class
`include, for example, (1) a CRT display
`wherein visual elements* of the image or
`message originate at the light-emitting
`screen of a cathode-ray tube, (2) a flat panel
`display
`(non-CRT
`display
`system*)
`wherein visual elements* of image or mes-
`sage are the result of light producers or
`light controllers arranged in a tangible
`mechanical grouping or array, (3) any
`matrix arrangement of light-generating or
`light-controlling display elements* with
`
`selective electrical display control, or (4)
`any plural arrangement of segmented light-
`generating or light-controlling display ele-
`ments* with selective electrical display
`control.
`
`(3) Note. Claimed subject matter directed to a
`display
`function
`(waveform) generator
`combined with a display is classified herein
`unless there is claimed structure relating to
`the manner in which the waveform is
`detected or measured.
`
`(4) Note. Generally, significantly claimed
`structure external to this class, claimed in
`combination with subject matter under the
`class definition above, which displays or
`produces an image or message related to
`such external structure or its function, is
`classified in the class appropriate to the
`external structure; however, a significantly
`claimed operator interface claimed in com-
`bination with computer graphics processing
`such as attribute processing or graphic
`manipulation, which displays or produces
`an image or message related to such opera-
`tor interface is classified herein. Further,
`nominally claimed structure external to this
`class, claimed in combination with subject
`matter under this class definition, is classi-
`fied in this class unless provided for in the
`appropriate external class.
`
`(5) Note. This class provides for peripheral
`input devices which include a manually
`actuatable selective means (e.g., keyboards,
`light pens, joysticks, mice, and touch tab-
`lets etc.) to selectively input the informa-
`tion data to the selective display control
`which translates the selective input into a
`message symbol or image, (e.g., a character
`or graphic object) on the display to an
`observer.
`
`(6) Note. This class also provides for display
`storage devices such as display memory
`with more than nominal recitation of their
`organization and structure claimed for stor-
`ing the previously created or generated data
`to be displayed on the display.
`
`(7) Note. Graphic objects of this class are
`defined by their coordinates, shape, size,
`and attributes. Such graphic objects define
