Abstract
Abstract A picture file system including a recording medium having a picture zone and a reduced picture zone divided therein. In a picture recording mode, a full-size picture data is recorded in the picture zone and a reduced picture of a predetermined data size corresponding to the full-size picture is recorded at a predetermined address in the reduced picture zone. In a picture retrieval mode, a plurality of the reduced pictures of the predetermined data size recorded at their predetermined addresses in the reduced picture zone are sequentially reproduced and displayed at the same time.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
104 words
A picture file system comprising: means for receiving and storing picture data; means for compressing said stored picture data to obtain reduced-picture data; recording medium means for storing therein said reduced-picture data at a predetermined address thereof, said reduced-picture data having a predetermined unit size; means for sequentially reproducing said reduced-picture data stored at said predetermined address to obtain a plurality of reproduced reduced-picture data in a picture retrieval mode; means for simultaneously displaying said plurality of reproduced reduced-picture data; means for selecting one of said displayed reproduced reduced-pictures; and means for reproducing and displaying an original not-reduced picture corresponding to said selected reduced-picture.
Claim 2
Dependent Claim
104 words
A picture file system comprising: means for receiving and storing picture data; means for compressing said stored picture data to obtain reduced-picture data; recording medium means for storing therein said reduced-picture data at a predetermined address thereof, said reduced-picture data having a predetermined unit size; means for sequentially reproducing said reduced-picture data stored at said predetermined address to obtain a plurality of reproduced reduced-picture data in a picture retrieval mode; means for simultaneously displaying said plurality of reproduced reduced-picture data; means for selecting one of said displayed reproduced reduced-pictures; and means for reproducing and displaying an original not-reduced picture corresponding to said selected reduced-picture.
Claim 3
Dependent Claim
51 words
A picture file system as set forth in claim 1, wherein said recording medium means is a disk-shaped recording medium, and the predetermined unit size of said reduced-picture data is an integer multiple of the data storage capacity of one of a plurality of tracks formed in said disk-shaped recording medium.
Claim 4
Dependent Claim
220 words
A picture file system comprising: means for inputting picture information; means for recording the inputted picture information as digital data at a predetermined address of a first zone of a recording medium; means for compressing and reducing the digital data of said inputted picture information; means for recording the compressed/reduced digital data at a predetermined address of a second zone of the recording medium in a desired unit size; means for commanding a picture retrieval; means responsive to said command for sequentially reading out a plurality of reduced picture data which are recorded at an address continuous from the predetermined address of the second zone of the recording medium; means for sequentially writing the read out reduced picture data one by one to a rectangular zone indicated by a predetermined address of one frame memory; means for displaying a content of the frame memory to which the reduced picture data are written on a display as one screen; means for selecting a desired picture from the plurality of reduced pictures displayed on the same screen; means for reading out an original picture data corresponding to the selected reduced picture and recorded on the first zone of the recording medium; and means for writing the read out picture data in the frame memory to display on the display as one screen.
Claim 5
Dependent Claim
220 words
A picture file system comprising: means for inputting picture information; means for recording the inputted picture information as digital data at a predetermined address of a first zone of a recording medium; means for compressing and reducing the digital data of said inputted picture information; means for recording the compressed/reduced digital data at a predetermined address of a second zone of the recording medium in a desired unit size; means for commanding a picture retrieval; means responsive to said command for sequentially reading out a plurality of reduced picture data which are recorded at an address continuous from the predetermined address of the second zone of the recording medium; means for sequentially writing the read out reduced picture data one by one to a rectangular zone indicated by a predetermined address of one frame memory; means for displaying a content of the frame memory to which the reduced picture data are written on a display as one screen; means for selecting a desired picture from the plurality of reduced pictures displayed on the same screen; means for reading out an original picture data corresponding to the selected reduced picture and recorded on the first zone of the recording medium; and means for writing the read out picture data in the frame memory to display on the display as one screen.
Claim 6
Dependent Claim
40 words
A picture file system according to claim 3 wherein said recording medium includes a disk shaped recording medium, and the unit size of said reduced picture has integer multiples of a capacity of one track of the disk-shaped recording medium.
Claim 7
Independent Claim
204 words
A method of displaying picture data comprising the steps of: inputting picture information; recording the inputted picture information as digital data at a predetermined address of a first zone of a recording medium; compressing and reducing the digital data of said inputted picture information; recording the compressed/reduced digital data at a predetermined address of a second zone of the recording medium in a desired unit size; commanding a picture retrieval; sequentially reading out in response to said command a plurality of reduced picture data which are recorded at an address continuous from the predetermined address of the second zone of the recording medium; sequentially writing the read out reduced picture data one by one to a rectangular zone indicated by a predetermined address of one frame memory; displaying a content of the frame memory to which the reduced picture data are written on a display as one screen; selecting a desired picture from the plurality of reduced pictures displayed on the same screen; reading out an original picture data corresponding to the selected reduced picture and recorded on the first zone of the recording medium; and writing the read out picture data in the frame memory to display on the display as one screen.
Claim 8
Independent Claim
204 words
A method of displaying picture data comprising the steps of: inputting picture information; recording the inputted picture information as digital data at a predetermined address of a first zone of a recording medium; compressing and reducing the digital data of said inputted picture information; recording the compressed/reduced digital data at a predetermined address of a second zone of the recording medium in a desired unit size; commanding a picture retrieval; sequentially reading out in response to said command a plurality of reduced picture data which are recorded at an address continuous from the predetermined address of the second zone of the recording medium; sequentially writing the read out reduced picture data one by one to a rectangular zone indicated by a predetermined address of one frame memory; displaying a content of the frame memory to which the reduced picture data are written on a display as one screen; selecting a desired picture from the plurality of reduced pictures displayed on the same screen; reading out an original picture data corresponding to the selected reduced picture and recorded on the first zone of the recording medium; and writing the read out picture data in the frame memory to display on the display as one screen.
