摘要:
An image storing device for compressing an original image, storing the compressed image, and expanding the stored image while enabling a high speed searching for stored image data is provided. An encoded data classification unit can classify the encoded and compressed data into reduced data output and an unreduced data output. Both the reduced and unreduced data output are stored and a selective reading unit can address this data. The data can be decoded and expanded and an arrangement control unit can arrange a sequence to the data so that the original image is reproduced when operating upon the unreduced data and when operating upon the reduced data, only encoded and compressed corresponding to scanning lines which are subject to reduced output are decoded and expanded after being reduced in a line direction.
摘要:
A document data filing apparatus automatically selects attribute values indicating visual features of a desired document from the code data of document data inputted. The attribute value generation unit generates attribute values indicating visual features of the document data inputted as coded data from the document data input unit. At this point, the presence or absence of dot data and specific words and characters are judged. The document data storage unit stores the document data in association with its attribute for retrieval. The attribute value designation unit makes an operator designate the attribute value as retrieval key to the document data to be retrieved The readout unit reads the document data corresponding to the designated attribute value from the document data storage unit. The display unit displays the document data. The retrieving technique is applied to a word processor.
摘要:
A word processor with a document retrieval function which successively and continuously displays retrieved documents which have been converted into code information and stored in the code information storage unit, so that by using a buffer memory of just little capacity, documents can be consecutively displayed at high speed, or at a specified high speed, or otherwise such consecutive display suspended and the documents generated one by one at high speed. In order to achieve this, the original code information is reduced so as to contain just enough information for retrieval purposes, and having been stored in the buffer memory, is used in the successive generation of the display image.
