Abstract

Abstract A phototypesetting process in which a character original is provided with coded bars which extend from the initial image line of successively identical image lines to the next to the last of such identical image lines as a means of generating a mark which signifies identical information content of such lines. The information mark is utilized to provide a recall order corresponding to the number of repetitions of a single such information content which would reproduce the scanned portion of the character associated with each single mark. The utilization of such recall orders in combination with repetition counters significantly reduces the storage capacity required for storing data to reproduce the character original in that the recall marks are utilized to inhibit storage of successively identical information and to recycle such information as frequently as required in accordance with the character original.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 175 words
A method of obtaining and processing control data for electronic phototypesetting apparatus wherein a character original is photoelectrically scanned image line by image line and point-by-point within each image line and a binary number is generated by means of a coding device in response to the successive black and white image line members of the character original scanned, which binary data is stored for use as control data, comprising the steps of disposing a scannable recall marking adjacent the character original in line with an image line and extending across at least several of the adjacent image lines which have the same information content as the mentioned image line, scanning the recall marking during scanning of the character original to produce a recall pulse, inhibiting with the recall pulse the storage of data of a further image line having the same information content as the precedingly scanned image line, and storing recall orders in response to the recall pulses for recalling the data of the first of the identical image lines during the setting process.
Claim 2
Independent Claim 175 words
A method of obtaining and processing control data for electronic phototypesetting apparatus wherein a character original is photoelectrically scanned image line by image line and point-by-point within each image line and a binary number is generated by means of a coding device in response to the successive black and white image line members of the character original scanned, which binary data is stored for use as control data, comprising the steps of disposing a scannable recall marking adjacent the character original in line with an image line and extending across at least several of the adjacent image lines which have the same information content as the mentioned image line, scanning the recall marking during scanning of the character original to produce a recall pulse, inhibiting with the recall pulse the storage of data of a further image line having the same information content as the precedingly scanned image line, and storing recall orders in response to the recall pulses for recalling the data of the first of the identical image lines during the setting process.
Claim 3
Dependent Claim 54 words
A method according to claim 1, wherein the step of providing the scannable recall marking is further defined as providing the scannable recall marking for each of adjacent image lines extending from a position in line with the first of the image lines to the next to the last one of identical image lines.
Claim 4
Dependent Claim 22 words
A method according to claim 1 comprising the step of storing a respective code combination for each of the scannable recall markings.
Claim 5
Dependent Claim 53 words
A method according to claim 3 comprising the step of registering a binary number corresponding to the frequency of the occurrence of each code combination allocated to the markings in a register, and permutating the register to recall image line information from the data store in accordance with the binary number code combinations.
