There is an effect that can be.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to examples.

  An embodiment of the present invention will be described below. As shown in FIG. 1, moving image data can be read into two moving image blocks from one recording medium, and position data can be read from one storage medium into three trajectory creation blocks as shown in FIG. It is like that. In the trajectory creation block 3, trajectory data is created from the position data (position data is data of the position where the moving image was shot), and the data is transferred to the five screen creation blocks. An input is given to the input device 6 from the outside, and the input device 6 gives a screen display support to the screen creation block 5 for the input. The screen composition block 5 sends a screen display signal to the display device 7 based on the data from the moving image reproduction block 2, the trajectory display block 4 and the input device 6 to display the screen.

  As shown in FIG. 2, the recording medium 1 has the position data 1 for the frame with respect to the frame data 1 of the moving image. Thus, data having position data for each frame is recorded.

  Next, data processing will be described with reference to the flowchart of FIG. First, the value of n is set to 0 in S1. Next, the position data n recorded on the recording medium is read in S2. In S3, it is determined whether or not the value of n is 1 in order to determine whether or not data is read for the first time. Since the value of n is 1 in the case of the first reading, the process of adding 1 to the value of n in S3. Do this for the first read. In step S5, in order to obtain a trajectory where the place photographed with the position data n has moved from the position data n-1, the difference between the position data n-1 and the position data n is obtained to obtain a moved vector. In S6, 1 is added to the value of n. In S7, it is determined whether the position data is the last data recorded on the recording medium. Here, when the position data is not the last, the process returns to S2 and the processes of S2, S3, S5, S6, and S7 are repeated until the position data becomes the last, and the respective movement vectors are obtained. When the movement vector is obtained for all the position data, in S8, an image that can display the locus on the screen by obtaining the locus using the movement vector is prepared. From S9, processing for reproducing a moving image is performed. In step S9, the frame data is read out, and in step S10, moving image data is created. Simultaneously with the processing of S9 and S10, the position data is read out in S11. In S12, the position data read out in S11 is found on the locus obtained in S8, and an image of where it is on the locus screen is created. deep. Using these S10 and S12, a moving image reproduction screen is output in S13.

  Next, the screen configuration of the present invention will be described with reference to FIG. On the playback screen 8, a moving image playback screen is displayed on the entire screen, an area 9 for displaying a locus on a part of the screen is created, and a locus 10 at the time of moving image shooting is displayed in the area 9. Further, during the reproduction of the moving image, the position 11 of the frame where the moving image is reproduced is displayed on the locus 10 by using an easily understandable mark 11. In addition, even when the moving image is paused in the middle, a mark is displayed on the locus having the position data of the paused frame.

  The figure of the locus | trajectory display area | region of Fig.5 (a) is shown. 12 in this figure is a pointer, and the mark 15 on the trajectory can be moved to an arbitrary position such as 13 or 14 by using this point. Assuming that frame N = a in FIG. 5B and frame N = b in FIG. 5C, when the mark 15 is moved to the position 13 using the pointer 12 during playback of the moving image, 13 corresponds. 5 (b) is reproduced, and when the mark 15 is moved to the position 14, reproduction is performed from the frame N = b in FIG. 5 (c) corresponding to 14. . By moving the mark 15 to an arbitrary point on the trajectory in this way, the moving image can be reproduced from the arbitrary point on the trajectory.

  Similarly, when the moving image is stationary, a still image corresponding to the point can be displayed by moving the mark 15.

  FIG. 6 shows another example of the screen configuration. There is also a configuration in which the playback screen and the trajectory screen are in the same area, and the trajectory image is displayed on the playback screen in a translucent manner. Further, there is a configuration in which the trajectory image is not translucent but displayed in combination with the playback screen.

  In addition, as shown in FIG. 7, there is a configuration in which the playback screen and the trajectory screen can be switched by switching means such as a switching button. In this case, when the moving image is reproduced on the trajectory screen, the mark moves on the trajectory in accordance with the frame.
