Abstract
Abstract An apparatus for cataloging and retrieving image data is programmed to store not only image data obtained by scanning each original but also reduced image data obtained by thinning these image data and search data used for the convenience in search operations. In a search operation, a plurality of reduced image data may be displayed simultaneously or sequentially with corresponding search data. Image data may be stored in a compressed form so that an increased amount of data can be stored. The apparatus may be programmed such that stored reduced image data are sequentially displayed while a specified key is depressed and particular image data corresponding to the data displayed when the key is released are displayed.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
137 words
An apparatus for cataloging and retrieving image data obtained by converting scannable documents into image signals, comprising memory means for storing image data, search data for searching image data stored in said memory means and reduced image data obtainable by thinning image data stored in said memory means, display means, input means including a search key which can be operated and released for entering a search command, and control means programmed to check whether said search key is operated, to sequentially display on said display means reduced image data from said memory means while said search key is operated, and to display particular image data from said memory means when said search key is released, said particular image data corresponding to the reduced image data being displayed on said display means when said search key is released.
Claim 2
Independent Claim
137 words
An apparatus for cataloging and retrieving image data obtained by converting scannable documents into image signals, comprising memory means for storing image data, search data for searching image data stored in said memory means and reduced image data obtainable by thinning image data stored in said memory means, display means, input means including a search key which can be operated and released for entering a search command, and control means programmed to check whether said search key is operated, to sequentially display on said display means reduced image data from said memory means while said search key is operated, and to display particular image data from said memory means when said search key is released, said particular image data corresponding to the reduced image data being displayed on said display means when said search key is released.
Claim 3
Independent Claim
37 words
The apparatus of claim .[.8.]. .Iadd.1 .Iaddend.wherein said control means is also programmed to sequentially display on said display means a plurality of reduced image data stored in said memory means each for a unit time period.
Claim 4
Dependent Claim
40 words
The apparatus of claim 1 further comprising compression-expansion means for compressing image data and reduced image data which are written in said memory means and expanding compressed image data and compressed reduced image data compressed by said compression expansion means.
Claim 5
Dependent Claim
73 words
The apparatus of claim 1 further comprising a scanner means, said control means being further programmed to catalog a scannable document by obtaining image data from image signals obtained by scanning said scannable document by said scanner means, generating reduced image data by thinning said image data, receiving search data related to said scannable document, and causing said reduced image data and said obtained image data to be compressed by a compression-expansion circuit.
Claim 6
Dependent Claim
20 words
The apparatus of claim 1 wherein said control means is further programmed to expand image data from said memory means.
Claim 7
Dependent Claim
35 words
The apparatus of claim 1 wherein said control means is also programmed to display on said display means both search data stored in said memory means and reduced image data corresponding to said search data.
Claim 8
Dependent Claim
32 words
The apparatus of claim 6 wherein said control means is programmed to simultaneously display on said display means a plurality of said search data and a plurality of said reduced image data.
Claim 9
Dependent Claim
56 words
The apparatus of claim 6 further comprising a scanner means, said control means being further programmed to catalog a scannable document by obtaining image data from image signals obtained by scanning said scannable document by said scanner means, generating reduced image data by thinning said image data, and receiving search data related to said scannable document.
Claim 10
Dependent Claim
76 words
The apparatus of claim 1 further comprising a scanner means, said control means being further programmed to catalog a scannable document by obtaining image data from image signals obtained by scanning said sacnnable document, generating reduced image data by thinning said image data, receiving through said input means search data related to said scannable document, and causing said reduced image data and said obtained image data to be compressed by transmitting to a compression expansion circuit.
Claim 11
Dependent Claim
20 words
The apparatus of claim 1 wherein said control means is further programmed to expand image data from said memory means.
