SOLUTION: A frame rate of recorded dynamic image data or an overwritten rate of the dynamic image data to be overwritten is set to each communication opposite party in a telephone number registration memory 25 in an information communication terminal. When the residual capacity of a recording medium 23 is a prescribed value or below, the data are recorded at a frame rate set to each communication opposite party. When there is no residual capacity of the recording medium 23 left, the data are overwritten to the file written in each communication opposite party at an overwritten rate set to each communication opposite party. Thus, the capacity of the recording medium 23 is utilized effectively.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a moving picture recording system for recording moving picture information on a medium.

[0002]

2. Description of the Related Art Conventionally, devices such as TV telephones for transmitting and receiving moving images to and from other parties for communication have become widespread. Where TV
In the process of talking with the other party over the phone, the moving image received from the other party is stored and stored on a recording medium such as a disk,
I may check the conversation again later. In some cases, the receiving side is away, and the received content, such as the content of a statement from the other party, is stored in a recording medium, and the content is later played back and confirmed.

However, in the process of recording moving image data on the recording medium on the receiving side, the remaining capacity of the recording medium may be exhausted, and important conversation contents may not be recorded. In particular, when the receiving side is a portable information terminal, the capacity of the recording medium is small to reduce the weight, and the capacity immediately becomes full during the recording process, so that conversation contents cannot be recorded. Therefore, a new capacity must be secured by interrupting the conversation once and erasing or overwriting the conversation contents recorded in the past, and the operation is complicated.

[0004] In order to solve this problem, for example, when the remaining capacity of the recording medium becomes small, low quality recording is performed, and when the remaining capacity becomes 0, an overwrite permitted area is set in the already recorded recording area. A method of setting and overwriting has been proposed (JP-A-6-217249).

[0005]

However, as described above, low quality recording is performed when the remaining capacity of the recording medium becomes small, and overwriting is performed when the remaining capacity becomes zero. Since the frame rate or field rate for quality recording and the overwritten ratio for overwriting are set uniformly regardless of the importance of the moving image data to be recorded or the moving image data to be overwritten, important moving images There has been a problem that data is recorded or overwritten with lower quality than desired quality, or that less important moving image data is recorded or overwritten with unnecessarily high quality.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has an object to record a moving image data to be recorded or a communication partner corresponding to moving image data to be overwritten or a recording date or time. It is an object of the present invention to provide a moving image recording system capable of effectively utilizing the capacity of a recording medium by adjusting the frame rate, the field rate, or the overwritten ratio.

[0016]

Embodiments of the present invention will be described below in detail with reference to the drawings. In the following drawings, the same symbols indicate the same or corresponding parts. FIG.
FIG. 1 is a diagram illustrating a system configuration of an embodiment when the present invention is applied to a portable information communication terminal.

In FIG. 1, a video signal from a camera 11 is encoded by a video encoding / transmission unit 12, and encoded data is transmitted to a transmission line 13. On the other hand, the encoded data transmitted from the information communication terminal 18 of the communication partner is input to the video receiving / decoding means 14 from the transmission path 13. The video signal obtained by decoding in the video receiving / decoding means 14 is converted into a video format for display by the display circuit 16 via the switch 15 and
7 is displayed. The switch 15 is normally connected to the a side.

A video signal obtained by decoding in the video receiving / decoding means 14 is stored in a recording medium 23 as video information storage means. When displaying the contents of the recording medium 23, the switch 15 is set to the b side to set the reproduction mode, and the image recorded on the recording medium 23 is reproduced and displayed on the display 17.

On the other hand, in the telephone number registration memory 25, the telephone number of the frequent communication partner is registered by operating the registration switch 26. Then, after the communication is started, the telephone number memory is searched by the caller telephone number 21, and the result as to whether the corresponding telephone number exists or not exists is output to the record management means 24.

Here, the recording management means 24 manages the write address of the recording medium 23 so as to record the moving image information on the recording medium 23 in frame units. The read address is managed so that the read from the recording medium 23 at the time of reproduction is also performed in the written frame order.

(Embodiment 1) First, Embodiment 1 of the present invention
Will be described. In the present embodiment, the telephone numbers of a plurality of destinations that frequently communicate are registered in a memory, and when a call is received from a communication destination registered in the memory, the destination is identified from the telephone number and communication is performed. This allows recording at a reduced frame rate or field rate according to the other party.

That is, in the present embodiment, a plurality of telephone numbers of the other party with
6, and is registered in the telephone number registration memory 25.
FIG. 2 shows the contents stored in the telephone number registration memory 25. When a call is received from a friend, a company relationship, a relative, or the like, when recording a moving image on the recording medium 23, the frame is dropped and recorded. That is, when a moving image is compressed for a frequent partner or a partner who can compress and record a moving image, the recording medium 23 is compressed.
Can be greatly reduced. In addition to the telephone number of each communication partner, the telephone number registration memory 25 stores information on how much a moving image is dropped according to each communication partner (for example, a friend of the telephone number A records one frame dropped in the FA frame). Etc.) are also stored. In FIG. 2, for example, FB>FA>
FD>FC> FS.

When a high-quality moving image is to be recorded by a communication partner, it is sufficient to set a normal moving image recording without setting a frame drop setting for the communication partner. Next, a method of recording on the recording medium 23 is shown in FIG.

First, the terminal is set to the recording mode (S2
1). If the recorded image has already been reproduced and it is not necessary to reproduce it again, the recording medium 23 is empty.
It waits for a recording start instruction (S22), and maintains the moving image recording standby mode (S23) until the instruction is given. The recording instruction is generated by, for example, detecting an incoming call from the partner terminal. When there is a recording instruction (S22), information on the remaining amount of the recording medium is notified to the recording management unit 24 by the remaining amount detecting unit 22, and it is determined whether the remaining amount is equal to or more than a predetermined value (S24).

If the remaining amount is equal to or more than a certain value, normal recording is performed (S25). That is, all the received frames are recorded. Until the communication is completed and the message recording instruction is stopped, the determination of the recording mode is always determined according to the remaining amount information.

When the remaining amount becomes equal to or less than the predetermined value, step S2
At 6, it is checked whether the remaining amount is 0, and if it is not 0, it is checked whether the incoming call is registered in the telephone number registration memory 25 (S27). When registered in the telephone number registration memory 25, low-quality recording according to the telephone number as shown in FIG. 2 (recording by removing one frame from FA to FD frame).
Is performed (S28). If it is not registered in the telephone number registration memory 25, fixed frame-drop recording is performed (one-frame frame-drop recording in the FS frame) (S29).
The low-quality recording by the frame-drop recording is performed, for example, in a frame-drop mode in which one frame is dropped every two frames, that is, one frame is skipped every two frames.

Here, the above-described method lowers the recording quality only when the remaining amount falls below a certain value. Therefore, when the recording frequency is low, high-quality recording can be performed without wasting the recording medium 23 wastefully. The purpose is to make it possible.

Then, the remaining amount decreases, and step S26
If the remaining is 0, recording is performed in the overwrite recording mode (S3
0). In this overwrite recording mode, in the recording area of the moving image information that has already been recorded, by setting and recording the overwrite permission area every plural frames, rather than completely destroying the already recorded image, This is the mode to save in the quality of dropped frames. When recording in the frame drop mode, the information is reduced to, for example, half by the frame drop means 19 of FIG. The information of these recording modes in recording and the information which is overwritten and saved as half the information are recorded and managed by the recording management means 24 and used for mode setting at the time of reproduction.

FIG. 4 shows a method of setting a mode during reproduction.
In FIG. 4, when there is a playback instruction from the operator first (S31), the process exits from the moving image playback standby mode (S32) and starts playback. The recording management means 24 determines whether the mode is a normal reproduction mode (S35), a mode for interpolated reproduction of dropped frame recording (S37), or a frame reading / interpolation reproduction mode (S36) when overwritten (S33). , S
34), display in each mode. In the overwritten mode, only the saved frames are read out, and the frames are interpolated and displayed. Similarly, information recorded in the frame drop mode is displayed by frame interpolation. The interpolation means 20 in FIG. 1 is a means for realizing the function of the frame interpolation, and in a simple system, can be realized by a method of repeatedly displaying the same frame.

In this embodiment, one frame is skipped in a plurality of frames in the frame drop mode. However, the frame rate is reduced to two frames in three frames or three frames in four frames, and the frame drop rate is reduced. Can be increased, and after one round of overwriting, overwriting can be repeated while allowing further display of dropped frames.

In the above description, the frame drop is described with reference to the frame. However, the frame may be dropped with reference to the field and the field interpolation may be performed. In the above description, FIG.
Accordingly, when the remaining amount of the recording medium 23 is equal to or less than a predetermined value and the remaining amount is not 0, the frame is dropped and recorded according to the dropped frame rate of the moving image set by the incoming telephone number. However, even if the remaining amount is not less than a certain value, the frame drop rate (FA to
It is also possible to record a moving image by dropping one frame in the FD frame. That is, the data may be compressed and recorded at the always determined frame drop rate according to the communication partner. Then, when a call is received from a communication partner whose telephone number is not registered in the telephone number registration memory 25, the frame may be recorded at a fixed frame loss rate (one frame frame loss recording in the FS frame).

In the above case, the telephone number registration memory 2
The moving image was always recorded at a certain frame-dropping rate, regardless of whether the telephone number was registered in No. 5 or not. However, since a videophone or the like always communicates with the other party using both moving images and sounds, it is not always necessary for the other party to record both moving images and sounds. If necessary, if only the voice is recorded, it is possible to sufficiently understand the requirements by listening to the voice recorded later. Therefore,
When a call is received from a specific destination registered in the telephone number registration memory 25, recording of a moving image may be prohibited. Further, the recording may be prohibited only when there is a call from a communication partner not registered in the telephone number registration memory 25. That is, a moving image may be prohibited for a call received from a communication partner other than the communication partner who frequently calls the user.

(Embodiment 2) In the present embodiment, when the remaining amount of the recording medium 23 becomes 0 and the recorded medium is overwritten, the overwritten file (file to be overwritten) is a telephone number. In the case of a moving image from a communication partner registered in the registration memory 25, the overwriting unit is changed. That is, when a file of a specific communication partner exists in the recording medium 23, by changing the overwriting unit according to the partner, many files of an unimportant communication partner are overwritten, and files of an important communication partner are overwritten as little as possible. In this way, it is aimed at fine file management.

That is, as shown in FIG. 5, the overwriting unit (overwriting every WA-WD frame) for the file to be overwritten is individually set in the telephone number registration memory 25 corresponding to the registered telephone number. In the case other than the registered telephone number, a fixed overwriting unit is set (overwriting every WS frame). In FIG. 5, for example, WB>WA> W
Let D>WC> WS.

If the remaining amount of the recording medium 23 is not 0 in the remaining amount check (S41) as shown in FIG. 6, it is checked whether the incoming call is registered in the telephone number registration memory 25 (S42). If registered in the telephone number registration memory 25, normal recording is performed in the recording file, and the telephone number is recorded at the head of the file (S43).
On the other hand, when it is not registered in the telephone number registration memory 25, the normal recording is performed in the recording file (S44).

Then, when the remaining amount of the recording medium 23 becomes 0 in the remaining amount check (S41), the mode shifts to the overwriting mode, and from the telephone number written at the head of the overwritten file, whether or not the file is a registration target file is determined. Check (S4
5). If the overwritten file is a file to be registered, the overwriting unit (WA to W) corresponding to the registered telephone number shown in FIG.
Overwriting is performed every D frames (S46).
If the overwritten file is not a file to be registered, overwriting is performed in fixed overwriting units (overwriting every WS frame) (S47).

(Embodiment 3) Next, Embodiment 3 of the present invention.
Will be described. In the present embodiment, in the process of recording moving image data on the recording medium, if the recording area becomes full, new moving image data is partially overwritten from the area where old moving image data is recorded. To secure a new recording capacity.

Here, the overwriting capacity is increased as the recording date of the moving image data is older.
In order to reproduce the moving image data before the information amount is reduced by being overwritten by new moving image data, the moving image is reproduced by interpolating the remaining data.

That is, in this embodiment, when the remaining amount of the recording medium 23 is not 0, the recording date (or time) is written at the head of each file when performing normal recording.
Then, when the remaining amount of the recording medium 23 becomes 0 and the mode shifts to the overwriting mode, the recording date (or time) written at the head of the overwritten file is read, and the recording date (or time) is old. The purpose is to increase the amount of overwriting. In other words, it is considered that the file becomes more important as the number of recording days (or time) passes, and the capacity of the recording medium 23 is appropriately secured by increasing the overwriting amount.

FIG. 7 shows overwriting units to be overwritten (overwriting every DA to DD frame) according to the date on which the overwritten file was recorded. Where, in general,
DA>DB>DC> DD. That is, the overwriting amount increases as the number of days passes.

This operation is performed when the remaining amount of the recording medium 23 is not 0 in the remaining amount check (S51) in FIG.
Normal recording is performed, and the recording date is written at the head of the file (S52). Then, when the remaining amount of the recording medium 23 becomes 0 in the remaining amount check (S51), the mode is shifted to the overwriting mode, and the recording date written at the head of the overwritten file is read and checked (S53). If the recording date is the same day, it is overwritten every DA frame (S5
4). If the recording date is one day ago, the data is overwritten every DB frame (S55). Similarly, the overwritten file is overwritten in the overwriting unit designated in FIG. 6 according to the recording date. In this case, the file to be overwritten is
Select from the oldest recording date.

(Other Embodiments) As described above, in the first embodiment, the unit of recording on the recording medium 23 is changed according to the communication partner registered in the telephone number registration memory 25. In the second embodiment, when the recorded moving image file is a file of a communication partner registered in the telephone number registration memory 25, the overwriting amount is changed according to the communication partner. In the third embodiment, the overwriting amount is changed at the time of overwriting according to the recording date of the recorded file.

However, by combining the first embodiment and the second embodiment, a recording unit for recording according to a communication partner,
When overwriting, the overwriting amount for the overwritten file may be changed. In addition, the first, second, and third embodiments may be appropriately combined and implemented according to applications.

In the third embodiment, in the above description, files to be overwritten are selected in order from the oldest recording date, regardless of the communication partner corresponding to the file to be overwritten. The recording is managed for each communication partner number, and when the remaining amount of the recording medium 23 becomes 0, the moving image data from the same communication partner is stored in the recording of the communication partner in the order of the file having the oldest recording date. It may be overwritten.

Here, when the remaining amount of the recording medium 23 becomes equal to or less than a predetermined value in the first embodiment, the input moving image is thinned out on a frame basis at a designated frame drop rate and stored in the recording medium 23. It is necessary to go. However,
In the case of an MPEG moving image, the moving image is composed of three types of pictures, I, P, and B, and the prediction dependency is shown in FIG.
become that way. The picture indicated by the arrow is the referenced picture. First, since the B picture is not referenced from any picture, it can be easily thinned out, and it is also easy to realize that all P and B are thinned out and only the I picture is used. On the other hand, when thinning out some P pictures, a simple method uses P3 which is the end of the prediction dependency.
You can only thin out in order from. However, in this case, the display intervals of the pictures become non-uniform, and the pictures look unnatural. Therefore, for example, when P2 is thinned out, the motion vector and the prediction error signal may be rearranged so that P3 can be predicted from P1. However, in a simple way P
2. It is necessary to perform decoding of P3 and re-encoding of P3. Therefore, as a means for realizing the frame thinning regardless of the prediction structure ("Study on frame rate conversion transcoder"'98 IEICE General Conference (D-11-76) Taji Yone et al.). This method proposes that if a motion compensation process is performed using a motion vector for the prediction error signal and the result and the motion vector are accumulated, an image at an arbitrary time can be decoded. Indicates that you can do it. In the first embodiment, by using the above means,
Even if a frame is dropped at an arbitrary frame drop rate, decoding processing with a small amount of calculation can be performed. Further, in the case of the second and third embodiments, even when performing interpolation reproduction for a file that has been overwritten and remains, reproduction can be easily performed by using the above-described means.

[0046]

As described above, according to the present invention,
Since the recording frame rate or the field rate can be adjusted according to the communication partner that records the moving image data, the capacity of the recording medium can be effectively used.

When the remaining amount of the recording medium is exhausted, overwriting can be performed only by lowering the quality of the already recorded information without giving up the recording. In the case of a recorded moving image file, the overwriting amount is adjusted according to the communication partner or the date or time of recording, so that the recorded file is not uniformly overwritten.
