Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an editing apparatus for editing and reproducing, for example, image data and audio data.

[0002]

2. Description of the Related Art Conventionally, in order to effectively produce a photographed image or moving image, the order of reproduction, the time, and the reproduction method are changed using an editing device as described below. Editing operations for recording after-recording and adding background music (BGM) were performed.

[0003] Such a conventional first editing apparatus comprises a video reproducing means for reproducing a desired video scene from a recording medium on which a video signal is recorded, and a video signal for recording a video signal reproduced by the video reproducing means. It comprises a recording means, and a control means for controlling the reproduction and recording operations of the video signal reproducing means and the video signal recording means. As described above, the above-described editing operation is performed using the two reproducing means and the recording means, ie, the video signal reproducing means on the reproducing side and the video signal recording means on the recording side.

Further, as shown in FIG. 3, a second editing apparatus described in Japanese Patent Application Laid-Open No. 7-222093 includes a signal processing means 41 for reproducing at least a video signal recorded on a recording medium 40, A memory 42 for storing an output signal of the processing means 41, and a switching means 43 for switching and outputting the output signal of the signal processing means 41 and the output signal of the memory 42
Signal processing means 41, memory 42 and switching means 43
And control means 44 for controlling the above. In this way, the video signal recorded on the recording medium 40 is edited and reproduced in a desired order by the switching of the switching unit 43 based on the editing instruction information from the control unit 44.

In the second editing apparatus described above, the editing instruction is input to the control means 44, and the video scenes recorded on the recording medium 40 are reproduced for each scene in a desired order based on the editing instruction. The output has been made. This editing instruction is recorded and held in a predetermined location on the recording medium 40 after the editing operation, and is set once by reading out the editing instruction prior to the reproducing operation when reproducing the same recording medium again. The editing instruction is reproduced, and the video scene recorded based on the editing instruction is reproduced for each scene in a desired reproduction order.

The memory 42 has, for example, a capacity capable of storing a still image (still image signal) of a video signal transmitted in a predetermined field or frame period among video signals transmitted continuously. The control unit 44 stores the still image signal and outputs the stored still image signal to the switching unit 43 according to the control signal from the control unit 44.

[0007]

However, the first editing apparatus of the prior art has been described above using two reproducing means and recording means, ie, a reproducing-side video signal reproducing means and a recording-side video signal recording means. Since the editing operation is performed, the editing operation becomes complicated, so that it is hardly used in ordinary households. Further, since two reproducing means and recording means are used, the cost of the editing apparatus is increased. was there.

In the second editing apparatus, since the signal processing means 41 is normally used only for reproducing a video signal, the efficiency is low, and an editing instruction is input to the control means 44. Only when the same recording medium is reproduced again after the operation, the editing instruction is recorded and held at a predetermined location on the recording medium 40 and the editing instruction is read out by the signal processing means 41, thereby reproducing the editing instruction set once. The video scene recorded based on this is reproduced in a desired reproduction order for each scene. However, since this editing instruction is the data itself, it is not reproduced according to the direct editing instruction but based on a control signal from the control means. Since the editing instruction is read, the editing operation becomes complicated, and the still image of the video signal transmitted in a predetermined field or frame period is stored in the memory 42. That capacity is required, because the large memory 42 of the storage capacity is required, there is a disadvantage that the cost of the editing apparatus is increased.

An object of the present invention is to provide an editing apparatus which can perform editing with a simple configuration in consideration of such points.

[0010]

According to the reproduction procedure, it is possible to designate an image composition, a special effect, and the like. Here, the reproduction procedure to be recorded in the reproduction procedure recording area of the recording medium by the reproduction procedure recording means is not the data of edited or processed sound or image supplied to the reproduction means, but the editing method / processing method for the reproduction means. It is an algorithm for causing such operations as above. This algorithm corresponds to a control program for controlling operations such as an editing method and a processing method for the reproducing means.

When the sound or image edited and processed based on the reproduction procedure is reproduced, the reproduction procedure recorded in the reproduction procedure recording area of the recording medium is read out by the reproduction procedure recording means, and the reproduction procedure is performed by the reproduction means. Supply.
