The slider base 242 has a certain length and extends in the horizontal direction in the figure. The slider base 242 is color-coded for each moving picture to be played back, and the length in the horizontal direction is determined according to the ratio of the playing time of each moving picture.

  The slider knob 241 is placed on the leftmost side of the slider base 242 in FIG. 4 before the moving image to be reproduced first is reproduced. When the reproduction of the moving image starts, the slider knob 241 automatically moves rightward in the drawing as the moving image reproduction time elapses.

  With reference to FIG. 5, a description will be given of a process for determining the order in which video files are to be played before playback and assigning the playback time of each video file to the slider base 242. FIG.

  When the user instructs the filing apparatus 100 to select / extract a moving image file to be reproduced by operating the keyboard 132 or the like, this process is started. In step S41, the filing device 100 asks the user to input a subject ID or an examination ID, which is an attribute for distinguishing the subject. The user inputs at least one of the subject ID and the examination ID of the moving image to be viewed into the filing device 100 using the keyboard 132 or the like. When only the subject ID is input, the corresponding specific subject is specified, and when only the examination ID is input, the corresponding endoscopic inspection of the specific subject is specified.

  In step S42, the moving image file recorded in the storage device 120 is searched and extracted from the subject ID or examination ID input by the filing device 100. Here, if only the subject ID is input in step S41, all the video files of the endoscopic examination of the corresponding specific subject are extracted, and if only the examination ID is input, the specific subject All the corresponding endoscopic movie files are extracted. In step S43, the filing device 100 reads the reproduction time from the reproduction time information 63 recorded in the searched / extracted moving image file.

  In step S44, the filing device 100 calculates the length that the bar corresponding to each moving image file occupies on the slider base 242 according to the reproduction time of each moving image file. This length is obtained by dividing the reproduction time of the moving image file by the sum of the reproduction times of all the moving image files to be reproduced and multiplying this by the total length of the slider base 242. Furthermore, using the captured date and time recognized from the file name of the moving image file, the bars of each moving image are obtained from the left in FIG. 4 in ascending order of the date and time, that is, the captured date and time from the oldest. These are sequentially arranged on the slider base 242 with different lengths.

  Next, with reference to FIG. 6, the filing apparatus at the time of moving image reproduction after the processing of FIG. 5 is completed and the moving image file to be reproduced first is read from the storage device 120 and expanded and ready for reproduction. The operation of 100 will be described.

  This operation is started when the operation icon 250 (FIG. 4) for moving image reproduction is clicked by operating the mouse 131 or the like and the user instructs the filing device 100 to reproduce the moving image file. In step S51, it is determined whether or not the stop icon 252 (FIG. 4) has been clicked by operating the mouse 131 or the like and a playback stop operation has been performed. If it is determined that the stop icon 252 has been clicked, the reproduction of the moving image file is stopped. On the other hand, if it is determined that the stop icon 252 has not been clicked, the process proceeds to step S52.

  In step S <b> 52, it is determined whether or not the user has moved the slider knob 241 on the slider base 242 using the mouse 131, the keyboard 132, or the joystick 133. If it is determined that the slider knob 241 has not been moved, the process proceeds to step S53 where the slider knob 241 is moved rightward by a predetermined distance on the slider base 242 to jump to the frame corresponding to the destination of the image file to be reproduced. In S54, the frame is reproduced. Next, the process proceeds to step S55.

  In step S55, whether or not the position of the slider knob 241 is close to the end position of the movie file currently being played back, that is, the position of the slider knob 241 on the slider base 242 is to the boundary with the bar of the movie to be played next. It is determined whether or not the position immediately before the end has a predetermined distance. If it is determined that the position of the slider knob 241 is close to the end position, the process proceeds to step S56, and the moving image file to be reproduced next is read from the storage device 120 and decoded (expanded) to prepare for reproduction. Then, after the position of the slider knob 241 is moved to the start point at the left end of the next moving image file, the reproduction of the next moving image file is started, and the process returns to step S51. On the other hand, if it is determined in step S55 that the position of the slider knob 241 is not close to the end position of the currently reproduced moving image file, the process immediately returns to step S51.

  On the other hand, if it is determined in step S52 that the slider knob 241 has been moved, the process proceeds to step S57. In step S57, the filing device 100 determines whether or not the position of the slider knob 241 is within the area of the moving image file currently being reproduced. If the slider knob 241 is not within the bar area of the same file, the moving image file positioned at the destination of the slider knob 241 is read from the storage device 120, opened and played in step S53. On the other hand, when the slider knob 241 is within the bar area of the same file in step S57, the process proceeds to step S53.

  As a result, it becomes easy to select and arrange a large number of moving image files according to attributes and to reproduce the moving images seamlessly.

  In the first embodiment, the playback time of the moving image is recognized based on the playback time information 63 recorded at a predetermined position (such as the user area) of the head portion 65 of the moving image file 60. You may recognize based on the parameter "duration" produced as a standard when compressing by the JPEG2000 system.
