DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An image pickup apparatus (video camera) according to one embodiment of the present invention will be described below with reference to FIGS.

As shown in FIG. 1, a signal input from the camera 1 is first processed by a still image recording circuit 2 and a still image compression circuit 3 to generate still image data. To memorize. The storage medium is a medium such as a hard disk, an optical disk, a DVD, and a memory card, and is preferably a medium that can be randomly accessed. At this time, the microcomputer 5 creates the file management information 6 for the still image data and stores it in the storage medium 7. The microcomputer 5 is control means for controlling the storage medium 7 and the like.

[0010] Next, as shown in FIG. 2, the still image data selected by the title selection input circuit 10 is stored in the storage medium 7.
And reproduced by the reproduction circuit 8 and stored in the still image data memory. At this time, the file management information 6 is read from the storage medium 7. Then, a still image and a confirmation message are displayed on a display 4 such as a liquid crystal display or a CRT. These operations are controlled by the microcomputer 5.

Next, as shown in FIG. 3, the still image title data information 12 is added to the file management information 6 of the moving image data selected by the title insertion moving image data selection 11 and written to the storage medium 7. Then, a confirmation message is output on the display 4. Still picture title information 12
Is, for example, the file number of the still image file, the insertion position, and the like. Title insertion determines the title before shooting the video, and when recording the video, the title of the still image,
The title may be inserted into the file management information 6 of the moving image file and the still image title data 12 may be written into the file management information 6 at the time of reproduction after shooting the moving image file.

FIG. 4 shows file management information 6 before title file creation and file management information 13 after title file creation. Information of the related still image file, position information, and the like are stored as title data in the management information after the title insertion.

FIG. 5 shows a method of reproducing a file in which a title is inserted. When a video playback request with title 14 is input, the microcomputer 5 reads the title file management information 13 from the storage medium 7. Management information 13
The title still image data described in
, And input to the still image reproduction circuit 8, and the reproduction data is stored in the memory 9. Next, the moving image file is read from the storage medium 7, input to the moving image reproducing circuit 16, and stored in the moving image data storage memory 17. After that, the reproduction switching circuit 18 is set to the still image output mode, and after outputting the still image data for several seconds, it switches to the moving image data. As a result, it appears that the reproduction of the moving image starts after the still image title is displayed for several seconds on the monitor 4 and the liquid crystal. Instead of displaying a still image title for a few seconds, a superimposed video in which the title is inserted may be reproduced during reproduction of a moving image. In this case, the microcomputer 5 controls the reproduction switching circuit 18 to switch a plurality of times based on the position information stored in the file management information while one moving image is reproduced.

Since only the file management information is changed as a process at the time of title insertion, the master data is not changed. Therefore, the still image data can be separately reproduced as a still image, and the moving image data can be separately reproduced as moving image data, thereby improving usability. Further, since only the file management information is changed, the title can be easily changed, and the degree of freedom of editing increases. Further, the file management information is stored in the same storage medium as the title still image and the moving image in which the title is inserted, so that the file management information can be edited even if this storage medium is inserted into another camera or another device. It can be reproduced while maintaining the relationship between the still image title and the moving image.

The portion having the title of the still image data may be replaced with audio data. At this time, the audio title data is recorded in the file management information of the moving image, as in the first embodiment.

A second embodiment of the present invention will be described with reference to FIGS.

FIG. 6 is a diagram for explaining the outline of title insertion. The basic operation is the same as in the first embodiment.
When the still image data 25 is inserted between the moving image data 21 and the moving image data 22 composed of 19 to 24 in FIG. 6, the file management information created in FIG. This is performed by changing the file management information with the number added. At the time of reproduction, after the title insertion position number is read and the moving image is reproduced, the still image title data is output when the title insertion position is reached. At this time, the moving image data is in a pause state. After displaying the still image title for several seconds, the moving image data is reproduced again. This means that the still image title has been inserted.

Since this is realized by adding title insertion position data to the file management information as in the first embodiment, there is no change in master data, and the title can be easily changed.

Further, by storing and providing the title still image data on a recording medium, it becomes possible to use the data as a fixed title.

[0018]

According to the present invention, it is possible to easily insert a title and change an inserted title without changing moving image data serving as a master, and to manage a title insertion position by data. , It is possible to suppress title displacement.
