Title: Digital Address Generator.
IPC: G06V30/10
Filed: 1968-10-01
Abstract: 1,172,789. Character recognition. INTERNATIONAL BUSINESS MACHINES CORP. 1 Oct., 1968 [3 Oct., 1967], No. 46424/68. Heading G4R. Apparatus for generating digital representations of the address of a selected portion of a document comprises means for displaying a visible representation of the document, means for moving a marker over the visible representation of the selected portion, and means for generating digital representations of the position of the marker. A C.R.T. 20 scans the document 26 in an ageing raster, signals from a photomultiplier 22 sensing the document controlling the beam intensity in a display C.R.T. 42 fed with the same deflection voltages as the C.R.T. 20. The operator adjusts potentiometers 44, 46, 48 to specify the vertical and horizontal positions of an address marker and the horizontal position of an end-of-line barrier respectively, circuit 40 (dashed box) controlling the beam intensity to display the marker and barrier on C.R.T. 42 at the selected positions. With the marker and barrier positioned, the operator actuates an address indicate key which causes, under control of a clock-driven counter 76, the potentiometer settings to be digitized, stored and displayed at 34, 36, 38. The C.R.T. 20 now moves to the position of the marker (seek operation) the vertical and horizontal movements in this seek terminating separately under control of position comparisons at 98, 94 and 100, 96. When both components of the seek movement have terminated, C.R.T. 20 executes a curve-follow pattern for each character in the line (positioned at) in turn. The curve-following is for recognition and may be as in Specification 1,117,854. When end-of-line is detected by position comparison at 104, the C.R.T. 20 returns to an ageing raster, except that AND 106 prevents this as long as a character is being followed round. During the curve-follow operation, the display at C.R.T. 42 is on an enlarged scale and this permits further adjustment of the potentiometers 44, 46, 48 for greater accuracy, if desired. The digitized positions displayed at 34, 36, 38 are read by eye, punched into cards and entered into a computer. The same can be done for further fields of the document. The computer is subsequently used to control reading of a plurality of documents with the same format.
