Abstract
Abstract A computer program is disclosed by means of which graphical information can be directly represented in coded form in the internal memory of the computer. Subroutines are provided for testing, changing and writing graphical symbols in coded form in the computer by means of scanners identifying unique plotting points of the internally represented graphical grid.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
121 words
A method for processing digital signals representing graphical information which is to be visually displayed, said method comprising the steps of 1. reserving a portion of a word-addressable memory for an array of data items, each data item representing a graphical element in a rectangular array of graphical elements, 2. storing the coordinate position of a specific graphical element in said rectangular array, 3. accessing a particular data item representing said specific graphical element by utilizing said coordinate position, 4. comparing the data item representing said specific graphical element with a preselected data item, and 5. arithmetically altering said coordinate position to provide access to a data item representing another graphical element in a different coordinate position in said rectangular array.
Claim 2
Independent Claim
121 words
A method for processing digital signals representing graphical information which is to be visually displayed, said method comprising the steps of 1. reserving a portion of a word-addressable memory for an array of data items, each data item representing a graphical element in a rectangular array of graphical elements, 2. storing the coordinate position of a specific graphical element in said rectangular array, 3. accessing a particular data item representing said specific graphical element by utilizing said coordinate position, 4. comparing the data item representing said specific graphical element with a preselected data item, and 5. arithmetically altering said coordinate position to provide access to a data item representing another graphical element in a different coordinate position in said rectangular array.
Claim 3
Dependent Claim
13 words
storing the coordinate position of a specific graphical element in said rectangular array,
Claim 4
Dependent Claim
13 words
storing the coordinate position of a specific graphical element in said rectangular array,
Claim 5
Dependent Claim
25 words
The method according to claim 1 further comprising the step of comparing the coordinate position of said specific graphical element with a given coordinate position.
Claim 6
Dependent Claim
27 words
The method according to claim 1 further comprising the step of storing accessing, comparing and altering commands in the internal memory of a general purpose digital computer.
Claim 7
Dependent Claim
15 words
accessing a particular data item representing said specific graphical element by utilizing said coordinate position,
Claim 8
Dependent Claim
15 words
accessing a particular data item representing said specific graphical element by utilizing said coordinate position,
Claim 9
Dependent Claim
15 words
comparing the data item representing said specific graphical element with a preselected data item, and
Claim 10
Dependent Claim
15 words
comparing the data item representing said specific graphical element with a preselected data item, and
Claim 11
Dependent Claim
25 words
arithmetically altering said coordinate position to provide access to a data item representing another graphical element in a different coordinate position in said rectangular array.
Claim 12
Dependent Claim
25 words
arithmetically altering said coordinate position to provide access to a data item representing another graphical element in a different coordinate position in said rectangular array.
