2. Description of the Related Art Conventionally, as disclosed in, for example, Japanese Patent Laid-Open No. 2-155030, only a moving image is displayed on a display screen of a workstation, and a moving image is searched for on a device side which reproduces the moving image. However, such a method is not sufficient as a moving image search method on a workstation having the ability to handle multimedia data, and is not necessarily convenient.

[0003]

In the above-mentioned prior art, no consideration is given to the search of moving images, and when searching for a desired moving image, the search function of the moving image reproducing apparatus side must be used. However, there is a problem in that an interface that enables fine control of the moving image reproducing apparatus from the workstation side is required.

An object of the present invention is to store a part of a moving image as a still image in an external storage device of the workstation in advance, so that the moving image search process can be performed on the workstation side. An interface to control the moving picture playback device from the workstation side, and search for moving pictures that allows the workstation side to use only the basic functions of the moving picture playback device such as playing, stopping, and fast-forwarding. To provide a method.

[0005]

In order to achieve the above object, the present invention relates to a moving image search processing apparatus, wherein a still image is extracted from a moving image already recorded on a recording medium.
The second step of creating a table recording the correspondence between the still image extracted in the first step and the position on the recording medium, and the still image recorded in the table created in the second step. The third step of continuously displaying and stopping the still image being continuously displayed and selecting a still image close to a desired moving image and the position on the recording medium corresponding to the still image selected in the third step are displayed. And a fourth step of displaying a moving image following the selected still image obtained from the table, and displaying the still image and reproducing the moving image following the still image.

The first step is to mechanically extract still images from moving images at regular intervals.

[0007]

The table for storing the position of the still image and the corresponding moving image on the recording medium stores the still image and the position on the recording medium at that time when the still image is extracted from the moving image. Works like. This makes it possible to transmit the position of the moving image on the recording medium to the moving image reproducing device when the instruction to stop the continuous display of the still image is made, and the moving image reproducing device accurately reproduces the moving image continuous to the still image. be able to.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows a moving image retrieval apparatus according to this embodiment, 1 is a control apparatus for controlling the entire retrieval apparatus, and 2 is a still image extracting apparatus for extracting a still image from a moving image. 3, 3 is a moving image reproducing apparatus for reproducing the moving image, 4 is a display apparatus for displaying the reproduced moving image and the still image extracted by the still image extracting apparatus 2, and 5 is the moving image reproducing apparatus. An external storage device for storing the position of the moving image on the recording medium to be transmitted to the recording medium 3 and the extracted still image, and 6 is an input device for the operator to input. The input device 6 is used for the present search device to stop the continuous display of still images and to reconstruct a table for storing still images extracted from moving images and corresponding positions on the recording medium. To do.

Next, the procedure for extracting still images from the moving image of this embodiment at regular intervals will be described with reference to the flowchart of FIG.

First, in step S1, the interval time for extracting a still image from a moving image is input by the input device 6. Then S2
Then, the moving image reproducing apparatus 3 reproduces the moving image.
Next, in step S3, the counter indicating the interval time between still image extractions is cleared. Next, in S4, a match between the counter indicating the extraction interval time and the time input in S1 is checked. If they match, S5 is executed. If they do not match, S6 is executed. Next, in S5, a still image is extracted by the still image extracting device 2, and the extracted still image is stored in the external storage device 5 to which the position on the recording medium read from the moving image reproducing device 3 is added.
Return to. In S6, it is checked whether the moving image is the end. If it is, the still image extraction process from the moving image is ended. If it is not, the counter value is incremented by 1 in S7 and the process returns to S4. .. Furthermore, in order to prevent the overhead at the time of search by recording redundant still images in this table in which still images that have been mechanically extracted at regular intervals are recorded, the table can be reconfigured by the operator. .. The still images may not be extracted at fixed time intervals, but may be arbitrarily extracted by an instruction.

FIG. 3 shows a table storing the positions on the recording medium of the still image created in the flowchart of FIG. 2 and the following moving image.

In FIG. 3, 7 is an area for storing a still image storage address for storing a still image in the external storage device 5, and 8 is an area for storing a position on the moving image recording medium. Reference numeral 9 is a moving image recording medium. In the above configuration, this table is used for the moving image recording medium 9

First, in S8, a counter indicating the still image currently being displayed is set to the head of the table as an initial setting. Next, in S9, it is checked whether or not a still image is stored in the entry (counter number) in the table indicated by the counter value, and if stored, S10.
If not stored, the search processing ends. Next, in S10, the counter-th still image in the table is displayed on the display device 4. Next, in S11, the operator selects whether to display the moving image following the still image displayed in S10 or not. If the still image is a portion close to the moving image intended by the operator, and if it is necessary to display the moving image that follows the still image, S11 is executed, and if it is unnecessary, S12 is executed. Next, in S12, the counter indicating the still image storage address in the table is positioned at the next still image, and the process returns to S9. In S13, the position of the moving image corresponding to the counter position on the recording medium is extracted from the table. Next, in step S14, the position on the recording medium that has been taken out is transferred to the moving image reproducing apparatus 3, and the moving image reproducing apparatus cues so that the moving image can be reproduced from the still image corresponding to the position on the recording medium. Do. Next, in S15, a reproduction command is transferred to the moving image reproducing device, the moving image is displayed on the display device 4, and the search processing is ended.

As a result, the functions required on the moving picture reproducing apparatus side are only the fast-forwarding function and the reproducing function, and complicated processing such as moving image search can be realized only by a simple interface.
