    摘要： A data processing system for inputting data to a form display includes a scanner (93) for inputting an image of a form document to the system, a processor (92) for recognizing character and line patterns from the form document image supplied from the scanner to produce physical structure data of the document and logical structure data related to data input/output fields in the form document depending on the physical structure data so as to automatically produce based on the logical structure data a program to input data to the form display, a display screen (91) for presenting thereon a form display defined by the physical structure data or normalized data obtained by correcting the physical structure data to be adaptive to a cursor pitch, a data input key apparatus (91), and a printer (95) for producing a printout document based on the form display filled with the data.

    摘要： Method of and apparatus for converting a first two-dimensional image on first column direction and row direction scales (A, B) to a second two-dimensional image on second column direction and row direction scales (a, b) at a high speed, in which use is made of the periodicity of the positional relation between the image elements (P xm Y n ) of the first image arranged in matrix and having various data values and the image elements (Q mn ) of the second image arranged in matrix and having various data values to determine, for each one of the second image elements, four second image elements (P xm Y n , P xm+1Yn , P xmYn +1, P xm+1Yn+1) lying on the intersections between two adjacent rows (X m , Y m +1) and two adjacent columns (Y n , Y n +1) in the first image element matrix which rows and columns surround the second image element and constitute a reference frame (C mn ) for the second image element, and in which the data value for each second image element is calculated on the basis of the data values of the four first image elements associated with the first image element and the vertical and horizontal coordinates within the reference frame. Both of the above-mentioned periodicity and the coordinates are defined in terms of the ratios (A/a, B/b) between the first and second scales for the first and second two-dimensional images, i.e. magnifications.

    摘要： In order to utilize memo data written by hand at the time of retrieving the document, the original document image data is stored and, thereafter, a document image data with memo is separately input, the document mage data with memo being comprised of the original document image onto which is additionally written memo data by hand. The position of the document image data with memo is then brought into alignment with the original document image data and is collated to extract only those memo data written by hand. Then the kind of memo is discriminated, the process is effected depending upon the kind of memo, and the memo data is stored in the secondary data file for retrieval. To retrieve the document, the memo data of a plurality of documents are read out from the secondary data file depending upon the kind of memo that is designated, and are displayed as a look-up table. If the operator designates any one of them, the image of the corresponding original document is read out from the original document image file and is displayed.
