If the condition (any one of * .jpg, * .gif, * .avi, * .png, * .tiff) matches the data type of the current processing target list, it is stored in the display list in step S409. This is repeated until the DB list is completed, and a display list whose data type is “image” is acquired. Subsequently, a screen drawing step is activated in step S203, and as a result, a screen as shown in 1102 is displayed.

  If range designation is performed by moving the slider 303 on the screen 1102, the process proceeds to step S 208 to activate the range designation step in FIG. 5. In the range designation step, the display list head data and the time information value of the slider start point pointer are compared in step S502, the slider start point data is set in S504 to the matched display list data, and then the slider start point data is obtained. For the lists after the display list data, the data that matches the time information of the slider end point pointer in step S506 is set in the slider end point data in step S507. At the same time, slider start point data is set in scope start point data in step S508. In this case, the scope is drawn from the slider start point as an initial value.

  Next, a screen drawing step is activated in step S203, and a slider 303 indicating range designation on the screen, a scope 304 indicating the position of the thumbnail data being displayed, thumbnail data 306 corresponding to the scope, and 305 in FIG. The information linked to the slider (date and time information with a range specified and the number of data existing in the range) is displayed.

  Here, when a scope is designated as in the screen of 1103, the scope designation step of FIG. 6 is activated in step S209, and in step S603, the display list after the slider start point data is compared with the time information of the scope start point pointer. Set the list data that matches with the scope start point data. Subsequently, when the screen drawing step is activated in step S203, next, in step S606, the eighth list counted from the scope start point data is set as scope end point data, and in step S607, the scope end point pointer is determined from the time information. When the value is set, the position of the scope end point pointer is calculated from the scope start point pointer in step S702, a rectangle between the scope start point pointer and the scope end point pointer is drawn in step S703, and thumbnail data corresponding to the scope is drawn in step S704. draw.

  Next, in step S705, an information display step is activated to display information linked to the slider (the date and time information specified in the range and the number of data existing in the range) as shown at 305 in FIG. As a result, a screen as shown in 1103 is displayed.

  As described above, according to the above-described embodiment, a list of target data can be displayed from a large amount of data, and the combination of simple operation of specifying a data type and specifying a range using a slider bar is possible. Data can be narrowed down.

  In addition, it is possible to display data associated with the movement of the slider without switching the display screen.

  Furthermore, the scope display on the slider bar allows you to know the position of the data currently displayed on the screen within the specified range, and at the same time, by moving the scope on the slider, Data existing in an arbitrary range can be narrowed down and displayed.

  In other words, only the data within the condition specification range is displayed by the combination of data file attributes, and the target data is found from a large amount of data by switching the data to be displayed by changing the time information scale based on this. Can be made easier.

  Further, by displaying the position of the data currently displayed on the screen and moving it from the data thus narrowed down, it is possible to further narrow down and make it easier to find the data.
