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.
Claims5
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.
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.
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.
