  Embodiments of the invention will be described below with reference to the drawings.

(First embodiment)
FIG. 1 is a block diagram illustrating a configuration example of a recording / reproducing apparatus 100 according to the present embodiment. In the recording / reproducing apparatus 100, each block may be configured by hardware using a dedicated logic circuit or a memory, excluding physical devices such as an image sensor and a display element. Alternatively, the processing program stored in the memory may be configured by software by a computer such as a CPU executing the processing program.

  In FIG. 1, an input unit 101 acquires and outputs a moving image signal and an audio signal. In the present embodiment, the input unit 101 inputs a moving image signal and an audio signal supplied from the outside of the recording / reproducing apparatus 100. However, the input unit 101 includes an imaging unit and a microphone, and the captured video and microphone are used for audio. It is good also as a structure which acquires a signal.

  The control unit 102 controls the entire operation of the recording / reproducing apparatus 100 in accordance with an input from the operation unit 103. The control unit 102 includes a microcomputer, a memory, and the like, and controls the recording / reproducing apparatus 100 according to a program stored in the memory. The control unit 102 has a built-in recording medium interface (IF) for communicating data and commands with the recording / reproducing unit 106. The operation unit 103 includes various switches that can be operated by the user. Then, the operation unit 103 receives various instructions from the user and notifies the control unit 102 of them. The operation unit 103 includes a power switch, a switch for instructing start / stop of recording, a switch for switching the mode of the recording / reproducing apparatus 100, and the like.

  At the time of recording, the signal processing unit 104 encodes the moving image signal and the audio signal input from the input unit 101 according to a known encoding format such as MPEG, and compresses the information amount. In addition, processing necessary for recording moving image signals and audio signals is performed. Further, the signal processing unit 104 decodes the reproduced moving image signal and audio signal and expands the information amount at the time of reproduction. In addition, the signal processing unit 104 outputs information on the encoded amount (data amount) of the encoded moving image signal and audio signal to the control unit 102 during recording.

  The memory 105 stores moving image signals and audio signals. Each block of the recording / reproducing apparatus 100 processes the necessary moving image signal and audio signal by accessing the memory 105. The memory 105 stores various information such as file system information and management information in addition to the moving image signal and the audio signal, and further functions as a work memory for control by the control unit 102.

  The recording / reproducing unit 106 records and reproduces moving image signals, audio signals, or various types of information on the recording media 108 and 109. At the time of recording, the recording / reproducing unit 106 records the moving image data and audio data stored in the memory 105 on the recording medium selected as the recording destination among the recording medium 108 and the recording medium 109. The recording / reproducing unit 106 reproduces moving image data and audio data from one of the recording medium 108 and the recording medium 109 and stores them in the memory 105 during reproduction.

  In the present embodiment, the recording media 108 and 109 are configured as separate recording media independent of each other, and are random access recording media such as a hard disk (HDD) and a flash memory card. The recording / playback unit 106 manages moving images, audio data, and various types of information recorded on the recording media 108 and 109 as files according to a file system such as FAT (File Allocation Table). The recording / playback unit 106 has a known interface (IF) such as ATA, and communicates data and various commands with the recording medium IF in the control unit 102. The recording media 108 and 109 are configured so that they can be easily loaded and unloaded from the recording / reproducing apparatus 100 by a recording medium loading / unloading mechanism (not shown). 108, 109 or any one of them may be incorporated. As will be described later, the recording / reproducing unit 106 detects a state during recording of data on the recording media 108 and 109 and notifies the control unit 102 of the state. Although FIG. 1 shows the case where the number of recording media is 2, the number may be 3 or more.

  When writing / reading data (file) to / from the recording media 108 and 109, the control unit 102 controls the recording / reproducing unit 106 to reproduce file system data (management data) from the recording media 108 and 109. And stored in the memory 105. This file system data is data indicating the file name, file size, data recording address, and the like of data recorded on the recording media 108 and 109, and is management information for managing files. Further, the control unit 102 detects the unrecorded area and the remaining recording capacity in the recording media 108 and 109 based on the file system data. Then, the control unit 102 controls file writing and reading according to the read file system data. The control unit 102 updates the file system data stored in the memory 105 in response to the file writing to the recording media 108 and 109. The updated file system data is recorded on the recording media 108 and 109 by the recording / playback unit 106.

  Further, the user can instruct to switch the operation mode of the recording / reproducing apparatus 100 or start / stop moving image data recording by operating the operation unit 103. In this embodiment, when two recording media 108 and 109 are loaded, the user operates the operation unit 103 to arbitrarily select one of the recording media as a recording destination. Video data is recorded on a recording medium. Furthermore, the present embodiment has a relay recording function that automatically switches the recording destination to the other recording medium and continues to record a moving image when the remaining recording capacity is reduced during moving image recording.

  The output unit 107 outputs the reproduced moving image data and audio data to a display device outside the recording / reproducing apparatus 100. The display unit 110 displays moving images and various types of information on a display device such as a liquid crystal panel. The data bus 111 is used for transmitting and receiving data, various control commands, and the like between the units of the recording / reproducing apparatus 100.

<Processing in recording mode>
Next, the recording operation in the present embodiment will be described with reference to FIG. FIG. 2 is a flowchart illustrating an example of a recording processing procedure. 2 is performed based on the control of the control unit 102. The processing corresponding to the flowchart can be realized, for example, by executing a program (for example, stored in the memory 105) corresponding to the CPU or processor functioning as the control unit 102. In the following embodiment, the processing of a moving image will be described, but it is assumed that audio input together with the moving image is also recorded.

  First, when an instruction to shift to the recording mode is received from the operation unit 103, the recording / reproducing apparatus 100 transitions to a recording standby state in S201 and waits for an instruction to start recording. In the recording standby state, a moving image related to the moving image signal input by the input unit 101 is displayed on the display unit 110. The recording standby state refers to a state where at least an input moving image signal can be recorded on a recording medium in response to a recording start instruction from a user. In the recording standby state, the control unit 102 selects a recording medium as a recording destination from among the recording media 108 and 109 in S202, and stores information on the recording medium selected as the recording destination in the internal memory 105. As described above, the user can set one of the recording media 108 and 109 as a recording medium to be recorded by operating the operation unit 103. Hereinafter, a case where the recording medium 108 is selected will be described as an example.

  In the recording standby state, the control unit 102 determines whether a recording start instruction is input from the operation unit 103 in S203. If an instruction to start recording is input (YES in S203), the process proceeds to S204. On the other hand, when the recording start instruction is not input, the process proceeds to S215. In step S <b> 204, the control unit 102 sets the recording medium 108 currently selected as the recording destination as a recording medium to be reproduced, and stores it in the internal memory 105.

  FIG. 6 shows an example of a table storing information on recording destination recording media and playback target recording media stored in the memory 105 in S202 and S204. In the table 600 of FIG. 6, information on the recording medium is registered for each of the recording medium 601 as the recording destination and the recording medium 602 to be reproduced. The registered information may be any information as long as the information identifies the recording medium. FIG. 6A is an example of information stored when a recording start instruction is input. At this time, both the recording destination and the reproduction target recording medium are the recording medium 108.

  In step S <b> 205, the control unit 102 causes the signal processing unit 104 to encode the moving image signal input from the input unit 101 and stored in the memory 105. Data encoded by the signal processing unit 104 (encoded data) is stored in the memory 105.

  In the present embodiment, the data rate of the data encoded by the signal processing unit 104 is lower than the data rate that can be recorded on the recording media 108 and 109. Therefore, in the present embodiment, the encoded data is temporarily stored in the memory 105. Each time the data amount of the encoded data stored in the memory 105 reaches the first predetermined amount, the recording / reproducing unit 106 reads the encoded data from the memory 105 and records it. When the encoded data stored in the memory 105 decreases to the second predetermined amount (<first predetermined amount), the reading of the encoded data from the memory 105 is temporarily stopped, and the recording process on the recording medium is performed. Interrupt. By repeating such processing, writing to the recording medium is performed.

  The control unit 102 updates the file system data (management information) stored in the memory 105 on the basis of the recording position of the encoded data written this time each time one writing to the recording medium is completed. To do. Then, the control unit 102 controls the recording / reproducing unit 106 to read the updated file system data from the memory 105 and record it on the recording medium.

  Specifically, the writing to the recording medium will be described. The control unit 102 controls the recording / reproducing unit 106 in S206 to create a new file for recording the encoded data on the recording medium 108 selected as the recording destination. And open. In step S207, the encoded data is recorded for this file. After starting the recording, the control unit 102 determines whether or not a recording stop instruction is output from the operation unit 103 in S208. If a recording stop instruction is output (“YES” in S208), the control unit 102 proceeds to S213. In S213, the control unit 102 controls the recording / reproducing unit 106 to close the file being recorded and stop the recording of the moving image. Then, the control unit 102 stops the encoding of the moving image signal by the signal processing unit 104 in S214.

  On the other hand, when there is no instruction to stop recording (“NO” in S208), the control unit 102 detects the remaining recording capacity of the recording medium 108 selected as the recording destination based on information from the recording / reproducing unit 106. In step S209, the control unit 102 determines whether the remaining recording amount is equal to or greater than the threshold amount. As a result, if the remaining recording amount is equal to or greater than the threshold amount (“YES” in S209), the process returns to S207, and the encoding of the moving image and the recording process are continued. If the remaining recording amount is smaller than the threshold amount (“NO” in S209), the control unit 102 controls the recording / reproducing unit 106 in S210 to close the file being recorded, and the current recording destination Recording of the moving image on the selected recording medium 108 is stopped. In step S211, the control unit 102 determines whether or not the remaining recording amount is equal to or more than the threshold amount on a recording medium 109 different from the recording medium 108 currently selected as the recording destination. As a result of the determination, when the remaining amount of the other recording medium 109 is smaller than the threshold amount (“NO” in S211), the process proceeds to S214. In S214, since no more recording is possible, the control unit 102 stops the encoding of the moving image signal by the signal processing unit 104.

  When the remaining amount of the other recording medium 109 remains (“YES” in S211), the control unit 102 changes the recording medium 109 as the recording destination in S212. At this time, the control unit 102 updates the recording destination recording medium information stored in the table 600 in the memory 105. For example, as shown in FIG. 6B, the recording medium 601 as the recording destination is changed from the recording medium 108 to the recording medium 109. At this time, the recording medium 602 to be reproduced remains the recording medium 108 and is not changed. As a result, when reproduction is performed after the recording is completed, the recording medium to be reproduced can be appropriately selected regardless of the recording medium that is the recording destination at the end of the recording. Then, returning to S206, the control unit 102 controls the recording / reproducing unit 106 to create a new file for recording the encoded data on the recording medium 109 selected as the recording destination, and subsequently record the moving image. .

  After stopping the encoding of the moving image in S214, the control unit 102 determines whether or not a mode switching instruction is output from the operation unit 103 in S215. If there is an instruction to switch to another mode (power off, playback mode) (“YES” in S215), the control unit 102 ends the recording mode process. On the other hand, when there is no switching instruction (“NO” in S215), the process returns to S201 and continues.

  An example of moving image data recorded on the recording media 108 and 109 by the above processing will be described with reference to FIG. In the present embodiment, a moving image recorded between a recording start instruction by a user and a recording stop instruction is referred to as a “scene”. If relay recording is not performed, one moving image data is generated in one scene. However, if relay recording is performed, one moving image data is originally stored in two recording media 108. And 109 are generated.

  In FIG. 4, a file 401 to a file 404 are moving image data 1 to moving image data 4 recorded on the recording medium 108, and a file 405 is the moving image data 5 recorded on the recording medium 109. Each of the files 401 to 403 corresponds to one scene, and the correspondence between the file and the scene is 1: 1. On the other hand, as for the scene 4, since the remaining recording capacity of the recording medium 108 is insufficient during the recording of the scene 4, the moving image is continuously recorded on the recording medium 109 by the relay recording function. Therefore, the moving image data corresponding to the scene 4 is the file 404 and the file 405, and the correspondence between the scene and the file is 1: 2.

  Next, the index screen in the playback mode will be described. When an instruction to display an index screen, such as an instruction to switch to a playback mode, is output, the control unit 102 outputs one of the recording media 108 and 109 selected as a playback target (recording medium 108, 109) In the above example, a plurality of scenes recorded on the recording medium 108) are detected. Then, the recording / reproducing unit 106 reproduces the head portion of the moving image data of each scene, decodes the one screen by the signal processing unit 104, and stores it in the memory 105. The head portion may be the start portion of the scene, or may be a portion after a predetermined time has elapsed after the start. Then, the signal processing unit 104 reduces the decoded image signal of the first screen, generates a representative image of each scene, generates an index screen including the representative images of a plurality of scenes, and displays the index screen on the display unit 110.

  FIG. 5 is a diagram showing an index screen displayed when moving image data is recorded on each of the recording media 108 and 109 as shown in FIG. FIG. 5A shows an index screen of the recording medium 108, and FIG. 5B shows an index screen of the recording medium 109.

  In FIG. 5A, a tab 502 for selecting the recording medium A (108) and a tab 503 for selecting the recording medium B (109) are displayed on the display screen 501. In the display screen 501, each moving image data is displayed as an icon so as to be selectable by a representative image 504 extracted from the moving image data. The moving image data can be selected using the cursor 505. In the present embodiment, the cursor 505 is represented as a frame surrounding the representative image 504, and the position of the cursor 505 indicates the selection state of the moving image data. The user can select arbitrary moving image data to be reproduced by operating the operation unit 103 and moving the cursor 505 serving as the frame between the representative images 504. By operating the operation unit 103 in a state where any moving image data is selected, the user can issue a reproduction instruction.

  5B is basically displayed in the same display form as that in FIG. 5A. Here, the tab 503 of the recording medium B (109) is selected. That is, the representative image 504 of the moving image data 405 recorded on the recording medium B (109) and the cursor 505 are displayed.

  The user can select a recording medium to be reproduced by operating the operation unit 103 and selecting one of the tabs 502 and 503. Then, a representative image of one of the plurality of recording media 108 and 109 and the selected recording medium to be reproduced is displayed on the display screen 501.

  In this embodiment, the representative image is generated by reproducing and decoding the top screen of each moving image data recorded on each recording medium. However, the method for generating the representative image is not limited to this. For example, at the time of recording, a still image may be generated in advance as a representative image from the top screen of each moving image data, and may be stored and recorded in a part of the moving image data (for example, a header area). In this case, the index screen is displayed by reading the representative image stored in each moving image data. Also, when one scene is divided and recorded across the recording media 108 and 109, when recording on the new recording medium 109 is started in S207 of FIG. An image may be generated anew.

<Processing in playback mode>
Next, processing in the playback mode will be described. FIG. 3 is a flowchart showing processing in the reproduction mode. 3 is executed by the control unit 102 controlling each unit. The processing corresponding to the flowchart can be realized, for example, by executing a program (for example, stored in the memory 105) corresponding to the CPU or processor functioning as the control unit 102.

  When a playback mode switching instruction is output from the operation unit 103, the control unit 102 selects a recording medium to be played back from among the recording media 108 and 109 in S301. For example, when the recording mode shown in FIG. 2 is switched to the reproduction mode, the recording medium set in advance as the reproduction target in S204 is set as the reproduction target recording medium as it is. That is, in the recording mode, the recording medium selected as the reproduction target in accordance with the recording start instruction is set as the reproduction target recording medium. In the present embodiment, as illustrated in FIG. 6, the recording medium to be recorded and the recording medium to be reproduced are independently managed by the table 600 in the memory 105, and the recording medium that is the recording destination at the start of recording is used. Are set in advance as reproduction targets (S202 and S204). Therefore, even when the recording medium of the recording destination is changed by relay recording (S212), the recording medium that is the recording destination at the start of recording can be selected as the recording medium to be reproduced.

  Next, the control unit 102 controls each unit so as to display the index screen of the recording medium to be reproduced in S302. The display unit 110 displays an index screen of a recording medium to be reproduced. The user can operate the operation unit 103 to select a desired representative image from the representative images displayed on the index screen and issue a reproduction instruction. The control unit 102 determines whether or not a reproduction instruction is accepted in S303, and if accepted (“YES” in S303), the control unit 102 proceeds to S304. In S304, the recording / reproducing unit 106 is controlled so as to reproduce the moving image data corresponding to the selected representative image. The recording / reproducing unit 106 reproduces the designated moving image data from the recording medium. The signal processing unit 104 decodes the reproduced moving image data, displays it on the display unit 110 instead of the index screen, and outputs it to the outside from the output unit 107. After the reproduction is started, the control unit 102 determines whether or not the reproduction stop condition is satisfied in S305. Specifically, it is determined whether an instruction to stop playback is output from the operation unit 103 or whether the moving image data being played has been played to the end, and the playback of the moving image file is continued until the playback stop condition is satisfied. When an instruction to stop playback is output from the operation unit 103 or when the video data being played back is played back to the end (“YES” in S305), the control unit 102 returns to S302 and indexes from the played video. The screen is switched and displayed on the display unit 110.

  If no playback instruction is given with the index screen displayed in S302 ("NO" in S303), the process proceeds to S306, and the control unit determines whether an instruction to change the recording medium to be played back is output. To do. If the change instruction is issued (“YES” in S306), the control unit 102 controls each unit to change the recording medium to be played back in S308 and switch the index screen displayed on the display unit 110. To do. For example, when the tab 503 is selected while the index screen of FIG. 5A is displayed, the playback target is changed to the recording medium B, and the index screen of the recording medium B is switched.

  Further, when the instruction to change the recording medium to be reproduced is not output (“NO” in S306), the process proceeds to S307 and the control unit 102 displays another index (power off, recording mode) while displaying the index screen. It is determined whether or not a switching instruction to) has been output. When the switching instruction is output (“YES” in S307), the control unit 102 ends the process of the reproduction mode and switches to the designated mode. On the other hand, when the mode switching instruction is not output (“NO” in S307), the process returns to S302 to continue displaying the index screen.

  As described above, in this embodiment, when an instruction to start recording is given, the recording medium selected as the recording destination is set in advance as a recording medium to be reproduced and managed in the memory 105. Thereafter, even when an instruction to display an index screen is output in the playback mode, the index screen of the selected recording medium to be played back can be displayed first with reference to the information on the recording medium to be played back in the memory 105. That is, in the present embodiment, the recording medium selected at the start of recording is to be reproduced, so that the recording medium at the recording destination is different between when recording is started and when recording is stopped, that is, when relay recording is performed. However, playback can be easily performed from the beginning of the scene by selecting the recording medium at the start of the previous recording. For example, as shown in FIG. 4, when the recording of the file 404 is started on the recording medium 108 by the recording start instruction, the file 405 is recorded on the recording medium 405 by the relay recording function, and the recording is stopped. However, the recording medium 108 is selected as a reproduction target.

  Therefore, when switching to the playback mode after stopping the recording of the file 405, the index screen of the recording medium 108 is displayed. Therefore, even when a user records one scene across two recording media by the relay recording function, the user can easily reproduce a moving image from the beginning of the scene.

  When switching to the playback mode after stopping the recording of the file 405, it is desirable to select the representative image of the file 404 with the cursor 505 on the index screen. By doing so, the user can easily reproduce the moving image from the beginning of the scene recorded by the relay recording without performing the operation of selecting the representative image by the operation unit 103.

  In the recording standby state after stopping recording by relay recording, when there is an instruction to start recording again, the control unit 102 sets the recording medium selected as the recording destination at that time as the reproduction target. The table in FIG. 6 is updated.

  Therefore, when the recording is stopped without performing the relay recording after the recording is started, the recording medium to be reproduced becomes the recording destination recording medium. Therefore, after that, the index screen displayed when switching to the playback mode is the index screen of the recording medium of the recording destination.

  Further, when the power of the recording / reproducing apparatus 100 is turned off, the control unit 102 retains the information of the recording destination recording medium in FIG. 6 even in the power-off state. Then, when the power is turned on next time, the recording medium to be reproduced is set as the recording medium to be recorded based on the held information.

  For this reason, after switching on the power, when switching to the playback mode in a state where no moving image is recorded, the index screen of the recording medium of the recording destination is displayed.

  In the present embodiment, the configuration for recording and reproducing moving images on two recording media has been described. However, the present invention can be similarly applied to a configuration for recording and reproducing moving images on three or more recording media. .

For example, in the configuration in which moving images are recorded and reproduced on the first to third recording media, three moving images of one scene are arranged in the order of the first recording medium, the second recording medium, and the third recording medium. It is also possible to perform relay recording across recording media. Even in such a case, since the recording destination and the recording medium to be reproduced are managed independently as shown in FIG. 6, even if the recording destination when the relay recording is stopped is the third recording medium, The first recording medium that is the recording destination at the start of recording is set as the recording medium to be reproduced. Therefore, when the playback mode is switched, the index screen of the first recording medium is displayed on the display unit 110. (Second Embodiment)
Next, a second embodiment will be described. In the second embodiment, in addition to the first embodiment, when a reproduction instruction is output when the index screen is not displayed, the moving image data recorded immediately before is reproduced from the beginning. Hereinafter, this function is referred to as a “record review function”.

  If the playback instruction is output from the operation unit 103 after the recording standby state is output in S201 in FIG. 2 until the recording start instruction is output, the control unit 102 is recorded on the recording medium to be played back. The last recorded moving image data is detected from the moving image data. Then, the control unit 102 instructs the recording / reproducing unit 106 to reproduce the moving image data recorded last. The recording / playback unit 106 plays back the designated moving image data. Then, the signal processing unit 104 decodes the reproduced moving image data and displays it on the display unit 110. In addition, when an instruction to stop playback is output or when playback of the moving image data is completed, the control unit 102 sets the recording / reproducing apparatus 100 to a recording standby state, and receives the moving image signal obtained from the input unit 101. Then, it is displayed on the display unit 110 again.

  For example, as shown in FIG. 4, the file 405 is recorded on the recording medium 109 by the relay recording function after the recording of the file 404 is started on the recording medium 108 by the recording start instruction, and the recording is stopped. In this case, the recording medium 108 is selected as a reproduction target. Therefore, after the recording of the file 405 is stopped, when a reproduction instruction is output in the recording standby state, the file 404 is reproduced from the top.

  It should be noted that the state where the index screen is not displayed can include a case where the power is turned off and the standby state is set. In this case, display is not performed on the display screen 501, but the moving image data recorded immediately before may be reproduced from the top in accordance with the reproduction instruction.

Thus, even when a user records one scene across two recording media using the relay recording function, the user can easily check the moving image from the beginning of the scene without switching to the playback mode. It becomes possible.
(Third embodiment)
Next, a third embodiment will be described. It is also conceivable that the recording medium to be reproduced is removed from the recording / reproducing apparatus 100 in the recording standby state after recording the moving image by the relay recording. In such a case, in the present embodiment, the recording medium to be reproduced is changed to the recording medium selected as the recording destination.

  The operation in this embodiment will be described with reference to FIG. FIG. 7 is a flowchart showing an example of the procedure for changing the recording medium. Each process shown in FIG. 7 is performed based on the control of the control unit 102. The processing corresponding to the flowchart can be realized, for example, by executing a program (for example, stored in the memory 105) corresponding to the CPU or processor functioning as the control unit 102.

  In S701, the recording / reproducing apparatus 100 is in a recording standby state. However, this recording standby state is characterized in that it is after relay recording from the recording medium 108 to 109 as shown in FIG. Therefore, as shown in FIG. 6B, the recording medium at this time is the recording medium 109, but the recording medium to be reproduced is the recording medium 108. In step S <b> 702, the control unit 102 determines whether the recording medium has been removed based on the state of the recording medium detected by the recording / reproducing unit 106. If removal of the recording medium is detected (“YES” in S702), it is determined whether or not the recording medium removed in S703 is a recording medium to be reproduced or a recording destination. In this determination, the determination is made with reference to the contents of the table 600 at that time.

  If the removed recording medium is the reproduction target, the process proceeds to S704, and the content of the reproduction target recording medium 602 in the table 600 is changed. In the configuration of FIG. 1, when the recording medium 108 is removed from the recording / reproducing apparatus 100, the control unit 102 changes the recording medium to be reproduced to the recording medium 109. If the removed recording medium is the recording destination, the process proceeds to S705, and the contents of the recording medium 601 as the recording destination in the table 600 are changed. When the recording medium 109 is removed from the recording / reproducing apparatus 100 in the configuration of FIG. 1, the control unit 102 changes the recording medium to be reproduced to the recording medium 108. However, since the capacity of the recording medium 108 at this time is insufficient, an error notification may be performed together. If there is another recording medium with a sufficient capacity, that recording medium may be used as the recording destination.
