Description

  The present invention relates to an image pickup apparatus for shooting video, and in particular, means for continuously recording a continuous moving image within a range instructed by the user to start and end recording, and a predetermined time after the user instructs to start recording. The present invention relates to a technique for performing snap movie recording as a separate file during continuous moving image recording in an imaging apparatus having means for performing snap movie recording in which shooting automatically ends after elapse.

  As an apparatus for recording a moving image, a digital video camera (hereinafter referred to as DVC) that uses a randomly accessible recording medium such as a disk or a flash memory as a recording medium is widely used. Also, many digital still cameras (hereinafter referred to as digital cameras) used for recording still images have a function of recording moving images.

  As a feature of these devices, random access is possible and compatibility with other digital devices such as PCs is high, so a short video file (snap movie) is created and sent as an email attachment. It is also common to upload and publish on a web page.

  As a recording mode for DVC and digital cameras, as long as the capacity of the recording medium allows, continuous recording until the user's instruction is given, and the mode of use so far, 5 seconds for the purpose of e-mail delivery, etc. A device capable of selecting a snap movie recording mode capable of automatic recording by limiting time such as 10-second recording is conceivable (see Patent Document 1).

  However, since the recording apparatus as described above has only one means for recording, it is necessary to switch between the two modes for recording, and it is not possible to record a continuous movie and a snap movie at the same time. It was. For this reason, there is a problem that the desire to record a continuous moving image for a long time and the desire to record a desired video as a snap movie cannot be satisfied at the same time.

  Further, the snap movie has a possibility that the user may miss a desired video because of the short predetermined time.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide an imaging apparatus capable of recording as a snap movie without interrupting a continuous video and without missing a desired video. There is to do.

  Hereinafter, embodiments for carrying out the present invention will be described. FIG. 1 is a block diagram illustrating a configuration of an imaging apparatus according to an embodiment of the present invention. The imaging camera 101 is a camera for photographing that includes a lens and an imaging device. Incident light is converted into a video signal, and the encoder 1 (102-1) and the encoder 2 (102-2) are passed through a video signal processing unit (not shown). ).

  The encoder 1 (102-1) and the encoder 2 (102-2) are connected to a microcomputer 105 that supervises control of the entire imaging apparatus, and gives instructions in accordance with the operation of the imaging apparatus. The microcomputer 105 is connected with a Rec key 106 and a snap movie key 111 for the user to operate the imaging apparatus, and performs control corresponding to the user's operation.

  The snap movie key 111 is a two-stage switch and is divided into an S1 key 111-1 and an S2 key 111-2. In the first stage, S1 is turned on, and in the second stage, S2 is turned on.

  The microcomputer 105 is connected to a display unit 107 for displaying the status of the imaging apparatus, and controls a captured video, a reproduced video, a message display to the user, or the like as necessary.

  The encoder 1 (102-1) records the received video signal on the recording medium 110 as a continuous moving image file 108 in accordance with an instruction from the microcomputer 105. The encoder 2 (102-2) converts the received video signal into stream data 103 having a predetermined format. The converted stream data 103 is temporarily stored in the temporary recording medium 104 connected to the encoder 2 (102-2).

  A recording medium 110 is connected to the temporary recording medium 104, and the stream data 103 stored in the temporary recording medium 104 is recorded on the recording medium 110 as a snap movie file 109 in accordance with an instruction from the microcomputer 105.

  The operation and effect of the imaging apparatus configured as described above will be described below. FIG. 2 is a flowchart showing the operation of the image pickup apparatus according to Embodiment 1 of the present invention. First, the user operates the REC key 106 to (step S101) issue an instruction to the encoder 1 (102-1) and give a real-time video to the recording medium 110 to start a continuous moving image recording S102. Next, by operating the S1 key 111-1 (S104), the stream data recorded on the temporary recording medium 104 is time-shifted and displayed on the small screen 201 (S105).

  Next, by operating the S2 key 111-2 (S106), recording of the stream data 103 displayed in a time-shifted manner on the small screen 201 as a snap movie file 109 on the recording medium 110 is started. At this time, information on the recording start point of the snap movie file is marked on the continuous moving image file 108 being recorded on the recording medium 110. (S107). When the recording of the snap movie file 109 is finished after a predetermined time t (b), the time shift display on the small screen is also finished (S108).

At this time, information related to the recording end point of the snap movie file is marked on the continuous moving image file 108 being recorded on the recording medium 110. Next, when the user operates the REC key 106, the continuous moving image recording is ended. (S109)
FIG. 3 is a timing chart showing the user's operation and the operation and display of the image pickup apparatus when a snap movie recording instruction is issued during continuous moving image recording in the image pickup apparatus according to Embodiment 1 of the present invention.

  When the user operates the Rec key in the power-on state, continuous moving image recording is performed by the encoder 1 (102-1). At this time, on the screen 201, the continuous moving image standby display 201-a is switched to the continuous moving image recording display 202-b.

  In the power-on state, the stream data 103 is always recorded on the temporary recording medium 104 for a certain period of time by the encoder 2 (102-2).

  At this time, when the user operates the S1 key (S104), the small screen 202 appears, and the stream data 103 recorded on the temporary recording medium 104 is time-shifted and displayed on the small screen 201 after a predetermined time t (a). (S105). At this time, a snap movie standby display 202-a is displayed on the small screen 202.

  When the user further operates the S2 key (S106), recording of the stream data 103 displayed as time-shifted as a snap movie file 109 is started. At this time, on the small screen 202, a snap movie recording display 202-b is displayed. After a predetermined time t (b) from the start of recording of the snap movie file 109, the recording of the snap movie file 109 is finished and the small screen display 202 disappears (S108).

  As described above, in the imaging apparatus according to the present embodiment, the user can perform snap movie recording even during continuous moving image shooting. Furthermore, since there is a grace period of t (a), there is an effect that the possibility that the user may miss a more desirable scene can be reduced.

  In addition, the snap movie recording start point and end point are often important scenes in a continuous movie, so marking in the form of additional data of a continuous movie can be used as a guide for playback and editing operations. There is an effect that the load can be reduced.

  FIG. 4 shows an example of simplifying the structure of a continuous moving image when two snap movies are recorded simultaneously. The continuous moving image file has additional data in addition to the audio file and the video file. In addition, it has snap movie management data. The snap movie management data is composed of a recording start time and a recording end time of a snap movie taken simultaneously, and this functions as a guide for reproduction and editing.
