Method and apparatus for searching image information
First Claim
1. An image information searching apparatus, comprising:
- optical disk means for optically storing image information;
management storage means for storing management data corresponding to the image information, including a plurality of corresponding document numbers, page numbers, record numbers, and logical addresses;
means for generating, from the management data, a search record information table including sorted management data that is ordered in accordance with the corresponding logical addresses;
means for inputting a desired search record;
means for retrieving, using the search record information table, a logical address corresponding to the desired search record;
readout means for sequentially reading, using the search record information table and beginning at the logical address corresponding to the desired search record, current image information from said optical disk means;
display means for continuously displaying a screen image including the current image information that is sequentially read out by the readout means; and
means for stopping the display of the current image information, and for causing the display means to display a previously read image information, wherein the previously read image information was read by the readout means and displayed by the display means a predetermined number of screen images before screen image corresponding to the current image information.

Abstract
An image information search apparatus includes an input unit inputting a search start instruction and a search stop instruction, an image information storage unit for storing a plurality of pieces of image information, and a searching unit for, in response to the search start instruction, referring to the image information storage unit to sequentially read out predetermined some of the plurality of pieces of image information and display the readout image information, and in response to the search stop instruction, stopping referring of the image information storage unit and displaying image information a predetermined number of pieces of image information before image information displayed upon stop. In high-speed search/display such as page or document turn over search, when stop of a display is instructed, image information displayed when stop is determined can be displayed again.

11. A method of searching image information stored in an optical disk unit for desired image information, the method comprising the steps, performed by a data processing system, of:
-
generating a search start instruction; reading out in response to the search start instruction image information from the optical disk unit; sequentially displaying the read-out image information to form a screen image; generating a search stop instruction; stopping the sequential display of the read-out image information in response to the search stop instruction; and displaying, after stopping the sequential display of the read-out image information, the read-out image information of a screen image that was displayed prior to the read-out image information that was displayed when the search stop instruction was generated. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. An image information searching apparatus, comprising:
-
optical disk means for storing image information; a management table in which at least document numbers, page numbers, record numbers, and logic addresses of the optical disk means are stored; means for generating from the management table a search record information table in which document numbers, page numbers, and record numbers are sorted; input means for inputting search record information; means for obtaining the logical address from the management table, in accordance with the input search record information; reading means for sequentially reading out the image information; display means for displaying to-be-searched image information corresponding to the image information read by the reading means; instructing means for generating an instruction to stop the display means; and restoring means for causing, in response to the stop instruction, said reading means to stop reading the image information, and said display means to display to-be-searched image information corresponding to previously read image information. - View Dependent Claims (20, 21, 22, 23)
