Image reproduction device

Abstract

In a case where a thumbnail image is displayed at the time of insertion of an image file storage medium including an automatic reproduction file, the thumbnail image is displayed only for the image file which contains description of automatic reproduction in an automatic reproduction file. Also, a thumbnail image of an image file which contains description of non-automatic reproduction in the automatic reproduction file is replaced with a dummy image or displayed as a thumbnail image not apparently capable of being recognized in response to a user request.

1 . An image reproduction device which displays an image file storage medium having stored therein a plurality of image files with main image information and thumbnail image information in an arbitrary format, and an automatic reproduction file containing at least the description as to whether the automatic reproduction of said plurality of the image files is permitted or not and order in which said image files are reproduced, the device comprising:
 a read unit which reads each file information stored in said image file storage medium;   an input unit which selectively determines whether only the thumbnail image of the image file which contains the description of automatic reproduction in said automatic reproduction file read by said read unit is displayed or the thumbnail images of all the image files stored in said image file storage medium are displayed regardless of the automatic reproduction information of said automatic reproduction file;   a control unit which performs a control operation in such a manner that said read unit reads from said image file storage medium the thumbnail image selected by said input unit;   an image development unit which develops the image file read by said read unit;   a storage element into which the image data developed by said image development unit are written; and   an image display unit which reads and displays a list of the thumbnail images written in said storage element.   
     
     
         2 . An image reproduction device which displays an image file storage medium having stored therein a plurality of image files with main image information and thumbnail image information in an arbitrary format, and an automatic reproduction file containing at least the description as to whether the automatic reproduction of said plurality of the image files is permitted or not and order in which said image files are reproduced, the device comprising:
 a read unit which reads each file information stored in said image file storage medium;   a control unit which performs a control operation in such a manner that said read unit reads from said image file storage medium a thumbnail image of the image file which contains the description of automatic reproduction in the automatic reproduction file;   an image development unit which develops the image file read by said read unit;   a storage element into which the image data developed by said image development unit are written; and   an image display unit which reads and displays a list of the thumbnail images written in said storage element;   wherein said storage element holds dummy image data corresponding to a thumbnail image, and   said control unit performs the control operation in such a manner that a dummy image is read from said storage element in place of the thumbnail image of the image file which contains the description of non-automatic reproduction in said automatic reproduction file read by said read unit.   
     
     
         3 . The image reproduction device according to  claim 2 , further comprising:
 an input unit which selectively determines whether said thumbnail image is displayed as a dummy image or as a thumbnail image, wherein   said control unit performs the control operation in such a manner that a thumbnail image is read from said image file storage medium in a case where the thumbnail image is selected by said input unit, and a dummy image is read from said storage element in a case where the dummy image is selected by said input unit.   
     
     
         4 . An image reproduction device which displays an image file storage medium having stored therein a plurality of image files with main image information and thumbnail image information in an arbitrary format, and an automatic reproduction file containing at least the description as to whether the automatic reproduction of said plurality of the image files is permitted or not and order in which said image files are reproduced, the device comprising:
 a read unit which reads each file information stored in said image file storage medium;   a control unit which performs a control operation in such a manner that said read unit reads from said image file storage medium a thumbnail image of the image file which contains the description of automatic reproduction in the automatic reproduction file;   an image development unit which develops the image file read by said read unit;   a storage element into which the image data developed by said image development unit are written; and   an image display unit which reads and displays a list of the thumbnail images written in said storage element;   wherein said control unit reads thumbnail images of all the image files from said image file storage medium, and   said image development unit develops the thumbnail image of the image file which contains the description of automatic reproduction in the automatic reproduction file read by said read unit as a normal image and, also, develops a thumbnail image of the image file which contains the description of non-automatic reproduction in said automatic reproduction file as an image difficult to recognize.   
     
     
         5 . The image reproduction device according to  claim 4 , further comprising:
 an input unit which selectively determines whether display of a thumbnail image displayed as said image difficult to recognize is canceled or not, wherein   said control unit performs the control operation in such a manner that in a case where display of an image developed by said input unit as an image difficult to recognize is canceled, a thumbnail image corresponding to the image is read from said image file.   
     
     
         6 . An image reproduction device which displays an image file storage medium having stored therein a plurality of image files with main image information and thumbnail image information in an arbitrary format, and an automatic reproduction file containing at least the description as to whether the automatic reproduction of said plurality of the image files is permitted or not and order in which said image files are reproduced, the device comprising:
 a read unit which reads each file information stored in said image file storage medium;   an input unit which selectively determines whether only the thumbnail image of the image file which contains the description of automatic reproduction in said automatic reproduction file read by said read unit is displayed or the thumbnail images of all the image files stored in said image file storage medium are displayed regardless of the automatic reproduction information of said automatic reproduction file;   a control unit which performs a control operation in such a manner that said read unit reads from said image file storage medium the thumbnail image selected by said input unit;   an image development unit which develops the image file read by said read unit;   a storage element into which the image data developed by said image development unit are written;   an OSD generating unit which is controlled by said control unit to display an arbitrary OSD image; and   an image display unit which reads and displays a list of the thumbnail images written in said storage element.   
     
     
         7 . The image reproduction device according to  claim 6 , further comprising an image superposition unit to superpose inputs thereto from said OSD generating unit and said image development unit and to output superposed image data to said image display unit.
