In order to achieve the above object, according to the first aspect of the present invention, when recording image recording information (such as photographing with a video camera), an image is arbitrarily taken from outside. Means for capturing a still image serving as a single or a plurality of indices; means for assigning header data specifying a screen to each moving image to be recorded; means for integrally recording and managing still image data and header data And characterized in that:

[0008] For example, athletic meet where a program is prepared in advance, a trip where a sightseeing course is scheduled,
When the exhibition corner is a photo of a trade fair indicated by a pamphlet, etc., you can capture and record a still image for the index, such as a bookmark or sightseeing map that can be prepared at hand, as an index still image. This means that the header data of the moving image to be managed is integrated and used as an index at the time of reproduction.

Further, according to the invention of claim 2 of the present invention, a still image (such as a sightseeing map) captured as an index is displayed on a display, and one or more arbitrary positions of the still image are designated. Means for registering the designated position as coordinate data, and a point symbolizing the content to be recorded (a certain landmark) so that the specified position can be visually recognized. (A coordinate point), and means for integrally recording and managing the coordinate data and the point mark.

Here, the means for integrally recording and managing the coordinate data and the point mark means that the recording is performed at a place where the recording is performed (a sports ground or a sightseeing spot) without performing a complicated operation. This means that a still image (for example, a bookmark or a sightseeing map) that can symbolize the content to be recorded is created and recorded as an index screen. By doing so, it is possible to easily find the head during reproduction.

More specifically, the recording / reproducing apparatus according to the present invention captures a still image (such as a bookmark or a sightseeing map) to be used as an index, and records an image or music on an index screen with a touch input type display or the like when recording the image or music. Is pointed to by the point mark, and the coordinate position is recorded as heading data.

According to a third aspect of the present invention, at the time of reproducing image recording information in an image recording / reproducing apparatus, an arbitrary point on a still image which can symbolize the content of the recorded image information is designated. Means, means for converting the arbitrary point into coordinate data, means for converting the coordinate data into heading data indicating a recording start point, and means for heading recording information by specifying coordinate data. It is characterized by having.

According to the first and second aspects of the present invention, the index screen is created and recorded, so that the index screen is displayed at the time of reproduction as in the third aspect of the present invention, and the points displayed on the screen are displayed. By specifying the mark part, the recorded contents can be called up. Therefore, when playing back information such as recorded video and music,
The graphical index screen allows you to specify the content you want to play in an image, making it convenient and easy to find.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be specifically described below with reference to the drawings. Here, a video camera will be described as an example. FIG. 1 is a configuration diagram of the present embodiment. Hereinafter, an embodiment will be described for capturing a still image used for an index, converting the screen data into index data, and using the index data.

First, creation of index data and photographing will be described. First, a target image to be applied to the index is prepared. The screen may be a print of an athletic meet program prepared in advance or a guide map of an exhibition hall at an exhibition, or may be selected for a part of a landscape such as a tourist information board. Here, an athletic meet program is prepared as an embodiment, and an index input button of the instructing unit 2 is pressed to take a picture with the photographing unit 1. Then, the index screen A is recorded in the video data recording section of FIG. 2 which describes the recording medium 4 in detail, and at the same time, the header data A is also recorded in the header data recording section.

Next, when the call of the header data A is input by the index call button of the instruction section 2, the control section 3 displays the index screen data A on the display section 5. The display unit 5 is configured by a liquid crystal display device capable of touch input capable of inputting a command on a display screen.

Subsequently, an indexing command is sent from the instruction unit 2 to the control unit 3. The control unit 3 attaches header data for designating an index screen to the captured still image to the screen data, and stores the attached data in the recording medium 4.

Next, when taking a picture, the control unit 3 takes out the screen by inputting the header data of the screen data of the index by the instruction unit 2 and displays it on the display unit 5. Before shooting, by touching anywhere on the index screen (where you can symbolize the content to be recorded, for example, at the "Kakekko" place in the athletic meet)
The touched coordinates are recorded by the control unit 3 and stored in the coordinate data recording unit in the recording medium 4 as coordinate data. At the same time, a point mark is attached to the index screen at a position based on the coordinate data (FIG. 3). The point mark is stored in the recording section of the coordinate data in the recording medium of FIG. 2 as a pair with the coordinate data. At this point, FIG.
A point mark as shown below is a point indicating the beginning of the video shooting information to be shot.

Regarding the display of the point mark, a circle of a certain size is drawn translucently so that the point at the touched point becomes the center of the circle, and is saved (for the size of the circle,
(It is possible to make fine adjustments later.) In a later operation, the position of the point mark can be clearly notified to the user.

For example, the following guide bookmark is captured as it is by the photographing unit 1 of FIG. 1 and used as an index screen. Of course, besides capturing a paper medium such as a bookmark, it is also possible to capture a landscape from a high place or the like and use it as an index screen. Here, when an arbitrary point is touched, a circle of a certain radius centered on the touched point is visualized as a translucent point mark. The coordinate data is linked to the header data of the index screen by the control unit 3 and stored in the index data recording unit of the recording medium 4. In this way, the point mark portion can be set anywhere on the index screen, and is visualized translucently.

The video shooting information thus shot is stored in the video shooting information recording section of the recording medium of FIG. 2, and at the same time, the coordinate data (heading data) of the index screen and the header of the index screen. The data and the video data of the index screen are linked to the shot video shooting information and are stored as “index data” in the index data recording section of the recording medium.

Second, the use and reproduction of index data will be described. At the time of reproduction, the index screen is displayed on the display unit 5 by inputting header data of the index screen in the instruction unit 2. By touching the point mark part of the item to be reproduced on the index screen, the coordinate data of the point mark part is detected by the control unit 3, and the index data to which the coordinate data is added is taken out from the recording medium 4. . Therefore, video shooting information based on the data is displayed on the display unit 5 from the recording medium 4. In this embodiment, the display and input unit 5
, Like the touch input type liquid crystal, the display unit and the input unit,
Although it is assumed that the same liquid crystal display will be used,
It goes without saying that other displays may be used.

[0023]

According to the present invention, claims 1 and 2 are provided.
The described invention can take any still image as an index and can be utilized as a graphical index. In particular, since index creation and utilization operations can be performed at the recording site (such as an exercise site or a sightseeing spot), it is possible to create an index that does not require much time for index creation and that is easy to use.

Further, according to the third aspect of the present invention, even if the amount of recorded data becomes enormous, the contents to be reproduced at the time of reproduction can be easily called while looking at the index screen. In other words, by looking at the index screen, the recorded contents can be easily imaged, so that the head is more convenient than the conventional apparatus.

Further, since these operations can be performed with extremely few procedures using the display unit as an interface, they are particularly useful for use in recording and reproducing devices which are excellent in random access using disk media and the like in the future. It is.
