DECISION SYSTEM FOR PICTURE READOUT AREA

摘要

PURPOSE:To facilitate input operation for coordinate data on a decision on a picture readout area and to improve the precision of the coordinate data, by devising a carrier sheet and a control data input part. CONSTITUTION:A control data input part 30 consists of a keyboard 31 for inputting alphanumeric data, digitizer (coordinate reader) 32 for inputting the coordinate data, microcomputer 33 for controlling the whole input part, and interface 35 coupling with a sequence control part 34. The microcomputer 33, on the other hand, consists of blocks of an input buffer 36, readable and writable nondestructive memory 37 stored with coordinate values of TRs and BLi (i; integer) by carrier sheet numbers, coordinate value arithmetic part 38 for calculating a readout position, and output buffer 39 for coordinate values.
