Numbers indicating the time at which each image was captured are arranged in a table format of 2 rows and 2 columns so as to be similar to the arrangement of the corresponding images, that is, similar to the arrangement of the frame image display consisting of 2 rows and 2 columns. The display direction display portions 73 and 74 are displayed. Since these screening direction notation parts 73 and 74 correspond to the display example of a four-frame image of 2 rows and 2 columns, the viewing direction can be easily understood by looking at the numbers representing the time.

  As in the case of the screening direction notation unit 71 shown in FIG. 10, not all of the numbers representing the image capturing time of each image are used, for example, only the last two digits of the second unit. As shown in FIG. 12, it may be arranged in the vicinity of one corner of the corresponding image (preferably, the four frames of images are concentrated in one corner around the center where they are close to each other) and displayed as the presentation direction notation section 75.

(Modification 5)
Modification 5 will be described with reference to FIG. FIG. 13 is a front view illustrating a display example when the moving image is displayed according to the fifth modification. In the fifth modification, the viewer can know the time-series presentation direction of the moving image by using the bar chart 56 indicating the time-series position of the image being displayed according to the position of the cursor 57.

  As described above, the position on the time series of images displayed sequentially in time series as a moving picture is indicated by the cursor 57 that moves on the bar chart 56, and if the cursor 57 moves to the right, the moving picture moves forward. Conversely, if the cursor 57 moves to the left, the moving image moves in the backward direction. However, the movement of the cursor 57 on the bar chart 56 is enormous, for example, for 10 hours. When handling the number of frame images, the amount of movement is slight, and it is difficult to determine which direction is the left or right, that is, the forward direction or the backward direction, simply by looking at the cursor 57.

  Therefore, in Modification 5, for example, when an operation of pressing the pause button 53g is performed as a predetermined key operation in a moving image showing state as shown in FIG. 13, for example, the display control unit 46 is shown in FIG. Thus, a part of the bar chart 56 including the cursor 57 is magnified and displayed in a magnifying glass. By this enlarged display, the moving direction of the cursor 57 is visualized in the enlarged display portion. Therefore, the viewer can watch the moving direction of the cursor 57 by paying attention to the enlarged display portion where the movement is visualized, and if the cursor 57 moves to the right, the moving image is shown in the forward direction. On the contrary, if the cursor 57 is moved to the left, it can be easily understood that the moving image is shown in the backward direction.

(Modification 6)
Modification 6 will be described with reference to FIGS. 14-1 and 14-2. FIG. 14A is a front view illustrating a case in which the screening direction is the forward direction as a display example when the moving image is displayed in Modification 6. FIG. 14B is a display direction as a display example when the moving image is displayed in Modification 6. It is a front view which shows the case where is a backward direction.

  In Modification 6, when a plurality of images of two or four frames are simultaneously displayed on the same screen and a moving image is displayed in time series, a plurality of images displayed at the same time are superimposed without using symbols or the like. The state is partially overlapped and displayed so as to indicate the time-series presentation direction of the moving image. In this case, a plurality of images are partially overlapped and displayed so that a new image in time series is positioned on the front side of the display screen.

  In FIG. 14A showing the case where the screening direction is the forward direction, the older image A located at the upper left is the farthest side of the display screen, and the newer image D located at the lower left is the front of the display screen. The images A to D are superimposed and arranged so as to be superimposed little by little so as to be on the side. It can be seen that the moving direction of the moving image is the forward direction by such a partial overlapping arrangement.

  On the other hand, in FIG. 14-2 showing the case where the screening direction is the backward direction, the older image A located at the lower left is the farthest display screen, and the newer image D located at the upper left is the most display screen. These images A to D are superimposed and arranged so as to be superimposed little by little so that they are on the front side. It can be seen that the moving direction of the moving image is the backward direction by such a partial overlapping arrangement.

(Embodiment 2)
A second embodiment of the present invention will be described with reference to FIG. In the second embodiment, the frame display rate of the moving image can be freely changed in the state of the moving image, the foot switch 14 is used as a setting means for this, and the operation of changing the frame display rate is performed by the strength of the foot switch 14. It is what I do.

  Conventionally, the frame display rate can be changed by performing an operation of switching between high speed and low speed using a pull-down menu in a dialog that appears on the screen by a setting button operation (see, for example, Patent Document 2). Patent Documents 3 and 4 disclose a method of changing a frame display rate by operating a wheel mounted on a mouse or joystick. However, such a change operation of the frame display rate has problems such as having to keep an eye on the moving image being shown, and it is not easy to change the frame display rate. In addition, this is a method in which the operator operates by hand, and when the operator is concentrating on other pointing commands, it is difficult to change the frame display rate because it requires a concentrated concentration.

  In this respect, the second embodiment allows the frame display rate to be changed by operating the foot switch 14, thereby allowing the user to operate while watching the movie being shown, and the operator operates with the foot. Both hands can be used for other operations, and the frame display rate can be easily changed.

When any of the buttons 53d or 53c is pressed (step S1: Yes or step S2: Yes), the frame display rate set at that time is read (step S3). If not set, the default value is read. Next, according to the read frame display rate, the frame images in the folder F1 are read in the order of the frame numbers (when the playback button 53d is pressed) or in the reverse order (when the reverse playback button 53c is pressed). Update display is performed on the monitor 51 (step S4).

  In such a display state, it is monitored whether or not the pause button 53g is pressed (step S5), and if pressed (step S5: Yes), according to the instruction, the pause button 53g is paused (step S6). Return to step S1. If not pressed (step S5: No), it is determined whether or not the display of all the target frame images has been completed (step S7). If the display of all the frame images has ended (step S7: Yes), the moving image screening process ends.

  If the display of all frame images has not been completed (step S7: No), it is determined whether or not the foot switch 14 has been operated (step S8). If the foot switch 14 is operated (step S8: Yes), the frame display rate is changed and set according to the strength operation (step S9). That is, as in the case of an accelerator pedal of an automobile, the frame display rate is set to be faster as the foot switch 14 is depressed more strongly, and the frame display rate is set to be slower as the foot switch 14 is depressed more weakly.

  Thereafter, it is determined whether or not the image update timing according to the frame display rate set at that time has been reached (step S10). If not reached (step S10: No), the process waits until it is reached. (Step S10: Yes), the process returns to step S4, and the frame images in the folder F1 are arranged in order of their frame numbers (when the play button 53d is pressed) or in reverse order (in accordance with the frame display rate set at that time). When the reverse playback button 53c is pressed), it is updated and displayed on the main observation monitor 51 of the display unit 42 (step S4) to be shown as a moving image.
