§1 Information processing apparatus The information processing apparatus according to the present embodiment sets a section in moving image data including image information recorded during movement of a mobile object and incidental information associated with the image information. The information processing apparatus according to the present embodiment sets a section in moving image data, for example, by accepting an operation from a user or based on a predetermined setting.

  The setting of the section is executed for information included in the moving image data. The information related to the section setting may be information that can set the section. For example, the information related to the section setting is the reproduction time, speed, acceleration, or position information of the moving image data. Note that speed, acceleration, position information, and the like are included in the incidental information associated with the image information.

  When the information related to the setting of the section is the playback time of the moving image data, the information processing apparatus according to the present embodiment sets the section on the playback time axis of the moving image data, for example. For example, the information processing apparatus receives a predetermined operation from the user while displaying the image related to the reproduction, or performs a predetermined operation for designating a position (or range) on the timeline related to the reproduction of the moving image data. By accepting, a section is set on the reproduction time axis of the accepted video data.

  The information processing apparatus receives, for example, an upper limit value and a lower limit value of speed or acceleration. Then, the information processing apparatus identifies the incidental information including the speed or acceleration related to the range of the upper limit value and the lower limit value of the received speed or acceleration, and sets a section in the moving image data related to the specified range.

  Further, the information processing apparatus receives, for example, designation of position information related to the start point and end point of the section (for example, designation on a map). Then, the information processing apparatus identifies the incidental information including the position information included in the range of the position information related to the start point and the end point of the received section, and sets the section in the moving image data related to the specified range.

  The information processing apparatus according to the present embodiment sets a section in the moving image data by the method as described above. Then, the information processing apparatus according to the present embodiment acquires travel information of the moving body in the section based on the incidental information associated with the image information included in the section set by the method as described above. In the present embodiment, an example in which a section is set on the playback time axis of moving image data will be described in detail as an example of the section setting process.

Specifically, the information processing apparatus according to the present embodiment receives a delimiter setting operation from the user while reproducing moving image data. When the user performs an operation for setting a delimiter, the information processing apparatus specifies the reproduction position of the moving image data at the time of the operation. Then, the information processing apparatus sets a break for specifying the section at the specified reproduction position. In this embodiment, a section is set by setting such a break on the playback time axis.

  That is, the user can set a break at a desired reproduction position while viewing an image reproduced by the information processing apparatus according to the present embodiment. The user can set a desired section on the playback time axis of the moving image data by setting a break at a desired playback position.

  When a section is provided on the playback time axis of the moving image data, the information processing apparatus can specify image information included in the section as shown in FIG. When the image information included in the section is specified, the image information and the supplementary information are associated with each other, and thus the supplementary information in the time domain of the section is specified. In the present embodiment, the information processing apparatus acquires travel information for the section by analyzing the specified incidental information.

However, in the present embodiment, when a plurality of sections are set on the playback time axis of the moving image data, the time areas related to the sections continuous on the time axis as shown in FIG. Treated as one time domain. That is, in the present embodiment, a section set with a gap on the time axis or a section set so as to overlap on the time axis is treated as a section related to another time region. In the present embodiment, there may be a plurality of time regions in which sections are set. Of the delimiters that form a section included in one time domain in which this section is set, the delimiter that exists first on the time axis is called the “first delimiter”, and the delimiter that exists last on the time axis is the “last delimiter” This is called “break”.

  Note that the operation of the information processing apparatus when there are a plurality of time areas in which the section is set is the repetition of the operation of the information processing apparatus in the case where there is one time area in which the section is set as shown in FIG. Can be explained by Therefore, hereinafter, an operation of the information processing apparatus when there is one time region in which a section as illustrated in FIG. 1 is set will be described.

  Note that in each section shown in FIG. 1, the point in time before the time axis corresponds to the “first time point” in the present invention. The image information at the time point corresponds to “first image information”. Further, in each section shown in FIG. 1, the break time point on the back of the time axis corresponds to the “second time point” in the present invention. The image information at the time point corresponds to “second image information”.

  As described above, the information processing apparatus according to the present embodiment accepts an operation by the user, and sets a section as shown in FIG. 1 on the playback time axis of the moving image data recorded by the drive recorder. Then, the information processing apparatus according to the present embodiment acquires the travel information for the section by analyzing the incidental information associated with the image information included in the section as illustrated in FIG.

§2 Drive recorder §2-1 Configuration of drive recorder The information processing apparatus 1 according to the present embodiment processes moving image data recorded by the drive recorder. A drive recorder is a device installed to record the running state of a vehicle.

  The drive recorder 2 according to the present embodiment is installed inside a vehicle and is connected to a camera 31 that records the front in the traveling direction of the vehicle. In addition, the drive recorder 2 acquires electric power required for operation | movement by connecting with the battery of a vehicle. At this time, the drive recorder 2 may be connected to the battery via a cigar socket, for example, or may be directly connected to the battery. Further, the camera 31 may acquire power necessary for operation from the drive recorder 2.

  FIG. 3 shows a configuration example of the drive recorder 2 according to the present embodiment. The drive recorder 2 includes a microcomputer as a control unit that controls the entire apparatus. Specifically, the drive recorder 2 according to the present embodiment includes a CPU 20 that realizes various control functions by performing arithmetic processing, a RAM 21 that is a work area for arithmetic processing, and a nonvolatile memory 22 that stores various data. It has. The nonvolatile memory 22 is composed of, for example, a hard disk or a flash memory, and stores a program 221 as firmware, setting parameters, and the like. The function of controlling each part of the drive recorder 2 is realized by the CPU 20 executing arithmetic processing according to a program 221 stored in advance in the nonvolatile memory 22.

<Acquisition of supplementary information>
The drive recorder 2 includes a timer circuit 25 and an acceleration sensor 26 in order to acquire incidental information of the vehicle, and is connected to a vehicle speed sensor 81 of the vehicle. The incidental information is information indicating the traveling state of the vehicle.

  The timer circuit 25 generates a signal corresponding to the current time and outputs it to the CPU 20. For example, the timer circuit 25 includes an internal battery, and thus operates without receiving power supply from the outside, and measures an accurate time.

  The acceleration sensor 26 detects acceleration indicating the magnitude of impact applied to the vehicle in units of G of gravitational acceleration. The detected acceleration indicates an instantaneous value of acceleration at the current time, and has a magnitude in a direction corresponding to, for example, three axes orthogonal to each other or two axes. The acceleration sensor 26 outputs a signal corresponding to such acceleration to the CPU 20.

  The vehicle speed sensor 81 detects the traveling speed (km / h) of the vehicle. The detected traveling speed indicates an instantaneous value of the traveling speed of the vehicle at the current time. The vehicle speed sensor 81 outputs a signal corresponding to such traveling speed to the CPU 20.

  With these configurations, the drive recorder 2 can acquire current time information, acceleration information at the current time, and speed information at the current time as information included in the incidental information of the vehicle.

  In addition, the drive recorder 2 may further include a GPS receiving unit in order to acquire information related to the traveling position of the vehicle at the current time as one of information included in the incidental information of the vehicle. The GPS receiving unit receives signals from a plurality of GPS satellites, and acquires position information related to the traveling position of the vehicle at the current time. The acquired position information is represented by latitude and longitude on the earth, for example. The GPS receiver outputs a signal corresponding to such position information to the CPU 20. Thereby, the drive recorder 2 can acquire the position information of the vehicle at the current time as one of the information included in the incidental information of the vehicle.

  Accompanying information such as the acquired current time information, acceleration information at the current time, speed information at the current time, position information at the current time, etc. is associated with the image information acquired at the time at which the additional information is acquired in the RAM 21. Remembered.

  Note that the incidental information is not limited to information including all the information such as time information, acceleration information, speed information, and position information as described above. If at least the time information is included in the supplementary information, the supplementary information and the image information can be associated with each other and stored in the RAM 21.

<Acquisition of image information>
The drive recorder 2 includes a camera 31 for acquiring image information. The camera 31 is arranged at a suitable position inside the vehicle, for example, between the rearview mirror and the windshield, separately from the main body of the drive recorder 2. The camera 31 includes a lens and an image sensor, and can acquire image information electronically. In the present embodiment, the camera 31 is arranged at a position where image information about a region in front of the vehicle near the upper portion of the windshield can be acquired in a state where the optical axis is directed to the front of the vehicle.

  The drive recorder 2 may include a microphone in addition to the camera 31. This microphone is arranged at a suitable position inside the vehicle separately from the main body of the drive recorder 2. Thereby, the drive recorder 2 can acquire sound information by collecting sounds during driving through the microphone. Thus, the drive recorder 2 according to the present embodiment may acquire audio information together with image information.

<Recording video data>
As shown in FIG. 3, the drive recorder 2 includes an image processing unit 23 that processes image information (image data) acquired by the camera 31. The image processing unit 23 performs predetermined image processing such as A / D conversion, luminance correction, and contrast correction on the image information signal input from the camera 31, and digital image information in a predetermined format such as JPEG format. Is generated. Image information processed by the image processing unit 23 is stored in the RAM 21.

  A part of the storage area of the RAM 21 is used as a ring buffer. Using this ring buffer, image information processed by the image processing unit 23 is always stored. At this time, incidental information acquired by the clock circuit 25, the acceleration sensor 26, the vehicle speed sensor 81, and the like is always stored. The CPU 20 stores the auxiliary information and the image information in the RAM 21 in association with each other. That is, the CPU 20 associates the image information processed in the image processing 23 with the incidental information at the time when the image information was acquired by the camera 31 and stores it in the ring buffer area of the RAM 21.

  When the drive recorder 2 includes a microphone, audio information acquired via the microphone is also always stored using a ring buffer. The CPU 20 stores the audio information, the image information, and the incidental information in the RAM 21 in association with each other.

  Here, in the ring buffer, when data is stored up to the last area, it returns to the first area and new data is stored. Thereby, in the ring buffer, new data is sequentially overwritten on the oldest data. For this reason, the RAM 21 stores image information and incidental information for a predetermined period of time in association with each other. For example, image information and incidental information for at least 40 seconds are stored in the ring buffer area. The image information and the incidental information are recorded in the memory card 9 via the card slot 24. Also in the case where the drive recorder 2 includes a microphone, image information, supplementary information, and audio information for a past fixed time are stored in the RAM 21 in association with each other, and the image information, the supplementary information, and the audio information are stored in a card. Recording is performed on the memory card 9 via the slot 24.

  The card slot 24 is configured so that the memory card 9 can be attached and detached, and reads data from the inserted memory card 9 and writes data to the memory card 9. When a predetermined event such as an accident or a dangerous behavior occurs, the CPU 20 generates moving image data from the driving information stored in the ring buffer of the RAM 21. Then, the CPU 20 records the generated moving image data on the memory card 9 attached to the card slot 24.

  Here, driving information is information including image information and incidental information. Moreover, although the moving image data mentioned above is produced | generated only from driving information, in other embodiment, moving image data may be produced | generated from driving information and audio | voice information.

<User operation>
The drive recorder 2 also includes a recording switch 32 and an operation unit 33 as members that receive instructions from the user. These are arranged at suitable positions inside the vehicle such as the vicinity of the steering wheel separately from the main body of the drive recorder 2 so that the user can easily operate them. The recording switch 32 and the operation unit 33 are not limited to the configuration arranged separately from the main body of the drive recorder 2, and may be provided in the main body of the drive recorder 2.

  The recording switch 32 is a switch that receives a recording instruction to the memory card 9. By pressing the recording switch 32, the user can record the moving image data on the memory card 9 at a desired timing, such as when the user feels a danger although no accident such as a collision has occurred.

The operation unit 33 includes a plurality of buttons, and receives input such as various settings from the user. User operation contents received by the recording switch 32 and the operation unit 33 are input to the CPU 20 as signals.

<Others>
The program 221 stored in the non-volatile memory 22 may be able to be updated by reading the memory card 9 storing a new program with the card slot 24.

  The drive recorder 2 may include a communication unit for connecting to the in-vehicle LAN. For example, the communication unit is connected to the in-vehicle LAN, and communicates with other devices connected to the in-vehicle LAN. With this communication unit, the drive recorder 2 can transmit and receive data to and from other devices.

§2-2 Operation Example of Drive Recorder FIG. 4 shows an operation example in which the drive recorder 2 according to the present embodiment records moving image data on the memory card 9. The drive recorder 2 according to the present embodiment normally records moving image data for a predetermined time before and after the occurrence of the event in the memory card 9 when the occurrence of the event is detected as an operation for recording the moving image data. Recording and continuous recording for continuously recording moving image data for an arbitrary time in the memory card 9 in accordance with an instruction from the user when occurrence of an event is not detected. It is assumed that the memory card 9 is installed in the card slot 24 at the start of this operation example. Further, this operation example is executed under the control of the CPU 20 unless otherwise specified. In FIG. 4 and FIG. 6 described later, the step is abbreviated as “S”.

  The drive recorder 2 is activated, for example, by turning on an ignition switch of the vehicle. The drive recorder 2 executes a predetermined initial process when starting.

  Immediately after the initial processing is completed, the drive recorder 2 starts acquiring image information indicating the state of the surroundings of the vehicle by the camera 31, and acquiring auxiliary information by the time measuring circuit 25, the acceleration sensor 26, the vehicle speed sensor 81, and the like. . The acquired image information and supplementary information are stored in the ring buffer area of the RAM 21 (step 101). Thereafter, the image information and the incidental information are continuously stored in the RAM 21 while the drive recorder 2 is activated. For example, the image information and the incidental information are continuously stored in the RAM 21 at a rate of 30 times per second. At this time, the image information is stored at a frame rate of 30 fps (30 frames per second). The image information acquired at the same time and the accompanying information are associated with each other.

  Thus, while the image information and the incidental information are continuously stored, it is monitored whether or not an event for stopping the operation of the drive recorder 2 has occurred, for example, by turning off the ignition switch of the vehicle. (Step 102). For example, when the ignition switch of the vehicle is turned off (YES in step 102), the drive recorder 2 stops its operation.

  On the other hand, if an event for stopping the operation of the drive recorder 2 has not occurred (NO in step 102), it is monitored whether or not a predetermined event has occurred (step 103). For example, the condition for determining that a predetermined event has occurred is that any of the following conditions (A) to (C) is satisfied.

(A) The acceleration sensor 26 continuously detected a predetermined acceleration or more for a predetermined time or more. For example, the acceleration sensor 26 continuously detected an acceleration of 0.40 G or more for 100 milliseconds or more.

  (B) While the vehicle is traveling at a predetermined speed or more, the vehicle speed sensor 81 detects a predetermined deceleration or more within a predetermined period. For example, when the vehicle is traveling at a speed of 60 km / h or higher, the speed difference for one second at the deceleration detected by the vehicle speed sensor 81 is 14 km / h or higher.

  (C) The recording switch 33 is pressed by the user.

  In addition, the predetermined value and threshold value in each condition may be set and changed by the user.

  Condition (A) is a condition relating to a situation in which relatively strong acceleration occurs and the probability of occurrence of a vehicle collision accident is high. An event that satisfies the condition (A) is called “G detection”.

  The condition (B) is a condition related to a situation in which a relatively rapid deceleration has occurred in the vehicle and there is a high probability that an accident has been imminent. An event that satisfies this condition (B) is called “rapid deceleration”.

  The condition (C) is a condition related to a situation where a user (typically a vehicle driver) desires to record moving image data. An event that satisfies this condition (C) is called a “switch operation”.

  When any event occurs (YES in step 103), for example, the operation information for a total of 20 seconds including 12 seconds before the occurrence of G detection or sudden deceleration and 8 seconds after the occurrence is displayed in the ring of the RAM 21. Read from buffer. Further, for example, after the switch operation occurs, operation information for an arbitrary time is read from the ring buffer of the RAM 21. At this time, if necessary, the operation information may be read from an area other than the ring buffer. The arbitrary time may be a time set in advance as a set value stored in the non-volatile memory 22, or may be set via a memory card by specifying the time in the information processing apparatus. .

  Then, moving image data is generated from the read driving information. This moving image data shows the situation around the vehicle when the event occurs. The generated moving image data is recorded on the memory card 9 (step 104). At this time, information related to the generated event may be stored at the same time.

On the other hand, if no event has occurred (NO in step 103), it is monitored whether an instruction to start continuous recording by the user is input (step 105). For example, it is monitored whether or not a special operation such as a long press different from the normal operation is performed on the recording switch 32. If an instruction to start continuous recording is detected (YES in step 105), the operation information at the time when the continuous recording instruction is detected is determined from the ring buffer of the RAM 21 for each predetermined data amount or for each predetermined time. The driving information is read together, converted into moving image data, and recorded on the memory card 9 (step 106). This recording to the memory card 9 is continuously repeated until a stop instruction is input (NO in step 107). For example, when a special operation such as a long press different from the normal operation is performed on the recording switch 32, recording to the memory card 9 is stopped (YES in Step 107).

In this embodiment, when continuous recording is performed, the same operation as the instruction to start continuous recording is detected again, but the continuous recording is stopped. The configuration may be such that the continuous recording is stopped when an operation different from the instruction to start the continuous recording is detected, or automatically when a predetermined time elapses after the continuous recording is started. Alternatively, the continuous recording may be stopped. Note that the predetermined time, which is an instruction to stop continuous recording, is preferably longer than the time recorded in the memory card 9 in the case of normal recording.

  Note that the event monitoring process for stopping the operation of the drive recorder 2 according to step 102 may not be executed. At this time, for example, when the user turns off the ignition switch, a process for forcibly stopping the operation of the drive recorder 2 is generated and executed, whereby the operation of the drive recorder 2 is stopped.

  FIG. 5 illustrates a storage state of the moving image data stored by the operation of the drive recorder 2 in the memory card 9. As the data storage structure in the memory card 9, for example, a hierarchical folder structure (hierarchical directory structure) is adopted as shown in FIG. The moving image data recorded by the drive recorder 2 is stored in any folder of the hierarchical folder structure. A root folder F0 is provided at the top layer of the hierarchical folder structure. A moving image folder F1 is provided as a child folder immediately below the root folder F0.

  The moving image folder F1 stores moving image data D1 obtained when an event occurs. For example, each moving image data D1 is identified by using the time when the event occurred or the like as the file name.

§3 Operation Example Next, an operation example in the present embodiment will be described with reference to FIG. FIG. 6 illustrates processing executed by the information processing apparatus 1 according to the present embodiment. The process exemplified below is realized as part of the process of reproducing the moving image data recorded by the drive recorder 2. However, the processing executed by the information processing apparatus 1 according to the present embodiment is not limited to such an implementation method.

  Note that at the start of this operation example, moving image data recorded by the drive recorder 2 is stored in the storage unit 11 or a memory card 9 storing the moving image data is mounted in the card slot 15. And That is, it is assumed that the moving image data recorded by the drive recorder 2 can be reproduced by the control unit 12 at the start of this operation example.

  When the operation device 5 is operated by the user, the moving image data related to reproduction is selected from the moving image data recorded by the drive recorder 2 stored in the storage unit 11 or the memory card 9. In response to the selection, the information processing apparatus 1 according to the present embodiment executes a program according to the present process and starts information processing according to the present embodiment.

  First, in step 201, the control unit 12 accepts a start operation for setting a section on the reproduction time axis of moving image data while reproducing the selected moving image data.

  FIG. 7 shows an example of a screen displayed on the display 6 at this point. As shown in FIG. 7, the display 6 according to the present embodiment includes an image reproduction unit 50, a time display unit 51, a speed display unit 52, an intra-section travel information display unit 53, a button 54, a button 55, a button 56, An acceleration display unit 57, a volume adjustment bar 58, a brightness adjustment bar 59, a data selection start unit 60, a playback bar 61, a moving image operation unit 62, and a graph display unit 63 are displayed. The control unit 12 generates an image including these configurations and causes the display 6 to display the generated image.

The image reproduction unit 50 displays image information included in the moving image data related to reproduction. A plurality of pieces of image information included in the moving image data can be arranged on the reproduction time axis. Therefore, when the playback position (the playback time point in the entire playback time) is specified, the image information related to playback included in the moving image data is specified. The control unit 12 decodes the image information specified in this way. Then, the control unit 12 generates an image for displaying the image obtained by the decoding on the image reproduction unit 50.

  The time display unit 51 displays the time (date and time) when the reproduction target image information specified by the reproduction position of the moving image data is acquired. The control unit 12 acquires time information obtained by the timer circuit 25 from the incidental information associated with the image information to be reproduced. And the control part 12 produces | generates the time image displayed on the time display part 51 based on the acquired time information. The control unit 12 adds the time information acquired from the supplementary information associated with the image information that is the head on the reproduction time axis of the moving image data and the time information at the reproduction position to display on the time display unit 51. You may calculate the time information for doing.

  The speed display unit 52 displays the traveling speed of the vehicle at the time displayed on the time display unit 51. The control unit 12 acquires vehicle speed information obtained by the vehicle speed sensor 81 from the incidental information associated with the image information to be reproduced. Then, the control unit 12 generates a speed image for displaying the acquired speed information on the speed display unit 52.

  The intra-section travel information display unit 53 displays travel information about the section generated by the user's operation.

  For example, in the upper section of the intra-section travel information display unit 53, the total time in the set section is displayed. The total time in the set section indicates the time between the first segment playback position and the last segment playback position.

  In addition, for example, in the lower section of the intra-section travel information display unit 53, two of the travel information about the section to be displayed are displayed. For example, the time required for the section and the average speed are displayed in the lower part of the intra-section travel information display unit 53. In other displays, for example, the required time in the section and the average acceleration (G value) are displayed in the lower part of the intra-section travel information display section 53. The acquisition of travel information for the section will be described later. The control unit 12 acquires travel information about a section by a process described later, and generates an image for displaying the acquired travel information about the section on the intra-section travel information display unit 53.

  The buttons 54 and 55 are buttons for setting a delimiter on the reproduction time axis of the moving image data relating to reproduction. That is, when these buttons are pressed, the control unit 12 specifies the playback position of the moving image data at the time when the pressing is recognized, and sets a break at the specified playback position. That is, the user operates the operation device 5 and presses the button 54 or the button 55 at a desired timing while watching the image displayed on the image reproduction unit 50, thereby moving the moving image data on the reproduction time axis. A delimiter for specifying a section can be set. As shown in FIG. 1, by setting a plurality of such divisions, the control unit 12 can specify a section.

  The button 54 is a button for setting the first segment and the last segment on the playback time axis of the moving image data. In response to the first pressing of the button 54, the control unit 12 sets the first segment on the playback time at the time when the pressing is recognized. Further, in response to the second press of the button 54, the control unit 12 sets the last delimiter on the playback time when the press is recognized.

The operation for setting the first break (first press on the button 54) corresponds to the start operation for starting the process of setting the section. That is, in step 201, the control unit 12 is waiting for the first press of the button 54 while reproducing the moving image data. On the other hand, the operation for setting the last break (second press on the button 54) corresponds to an end operation for ending the process of setting the section.

  The button 55 is a button for setting a partition located between the first partition and the last partition. When the button 55 is pressed during the process for setting the section, the control unit 12 sets a break on the playback time axis at the time when the pressing is recognized. In other words, when the button 55 is pressed in a state where the button 54 is pressed only once, the control unit 12 sets a delimiter on the playback time axis at the time when the pressing is recognized. Hereinafter, the pressing operation of the button 55 performed during the process for setting the section is referred to as a “separation creating operation”.

  If the button 55 is pressed in any other state, that is, the button 54 has not been pressed once, or the button 54 has been pressed twice, the control unit 12 will Reset the set separator. That is, the button 55 is a reset button when the button 54 has never been pressed or when the button 54 has been pressed twice.

  The button 56 is a button for displaying a list of sections and travel information about the sections. The button 56 will be described later.

  The acceleration display unit 57 displays the magnitude of the acceleration of the vehicle at the time displayed on the time display unit 51 as an image. The control unit 12 acquires the acceleration of the vehicle obtained by the acceleration sensor 26 from the incidental information associated with the image information to be reproduced (accompanying information related to the reproduction position). Then, the control unit 12 generates an image for displaying the acquired acceleration on the acceleration display unit 57.

  In the example of the screen shown in FIG. 7, the magnitude of the acceleration is expressed by the distance between the origin and the circle. The direction of acceleration is expressed by the position of the circle. Further, in the screen example shown in FIG. 7, the acceleration display unit 57 represents the trajectory of acceleration once displayed.

  The volume control bar 58 is a bar for adjusting the volume of audio data included in the moving image data related to reproduction. The volume adjustment bar 58 is used when audio data is included in the moving image data. The user can adjust the volume by operating the operation device 5 and moving a slider present on the volume adjustment bar 58.

  The brightness adjustment bar 59 is a bar for adjusting the brightness of the image displayed on the image reproduction unit 50. The user can adjust the brightness of the image displayed on the image reproduction unit 50 by moving the slider existing on the brightness adjustment bar 59 by operating the operation device 5.

  The data selection start unit 60 is a button for displaying on the display 6 a screen for selecting desired video data from the video data recorded by the drive recorder 2 stored in the storage unit 11 or the memory card 9. . For example, it is used when the user wants to change the moving image data related to reproduction.

  The reproduction bar 61 is a bar for displaying the reproduction position of the moving image data related to reproduction. The reproduction bar 61 is also called a seek bar. The position of the slider in the reproduction bar 61 indicates the reproduction position of the moving image data related to reproduction. The user can change the reproduction position of the moving image data by operating the operation device 5 and moving the slider.

  The moving image operation unit 62 is used for operating reproduction of moving image data. The user can execute reproduction, pause, stop, and the like of the moving image data by operating the operation device 5 and pressing a button present on the moving image operation unit 62.

  The graph display unit 63 displays the acceleration and traveling speed of the vehicle in a graph. The vertical axis on the left in the figure represents the magnitude of acceleration. In addition, the vertical axis on the right in the figure represents the traveling speed. The horizontal axis represents time (seconds). The time indicates the acquisition time of the image information. Therefore, for example, the graph display unit 63 in FIG. 7 displays the acceleration and running speed of the vehicle from 14:53:43 on March 21, 2011 to 14:54:43. These accelerations and traveling speeds are acquired from the incidental information relating to the acquisition time.

  In step 201, the control unit 12 displays a screen as shown in FIG. 7 on the display 6 and waits for the first press of the button 54 by the operation of the operation device 5 by the user. When the button 54 is pressed for the first time, the control unit 12 advances the processing to the next step 202.

  Next, in step 202, the control unit 12 specifies the reproduction position of the moving image data being reproduced when the first press on the button 54 in step 201 is executed. Then, the control unit 12 sets the first break at the specified playback position. After setting the first break, the control unit 12 proceeds to the next step 203. That is, the image information displayed on the image reproduction unit 50 at the time when the first press on the button 54 is executed is specified, and the specified image information and the incidental information related to the image information are separated as information (first information). Information).

  FIG. 8 shows an example of a screen displayed on the display 6 at this point. As shown in FIG. 8, in the present embodiment, the control unit 12 displays an icon at a playback position where a break is set on the playback bar 61 in order to display a section set on the playback time axis of the video data. An image displaying is generated. In FIG. 8, the icon related to the first break is “S”. The user can change the playback position of the separator related to the icon by changing the position of the icon on the playback bar 61. The same applies to other icons described later. In addition, by selecting an icon on the playback bar 61, the delimiter information is read and displayed on the image playback unit 50, the time display unit 51, the speed display unit 52, and the like.

  Next, in step 203, the control unit 12 monitors whether or not an end operation for setting a section on the reproduction time axis of the moving image data has been performed. That is, the control unit 12 monitors whether or not the button 54 has been pressed for the second time.

  When the second press on the button 54 is executed, the control unit 12 advances the process to step 207. On the other hand, if the second press on the button 54 has not been executed, the control unit 12 proceeds to the next step 204.

  Next, in step 204, the control unit 12 monitors whether or not a segment creation operation has been performed. That is, the control unit 12 monitors whether or not the button 55 has been pressed.

  When the button 55 is pressed, the control unit 12 proceeds to the next step 205. On the other hand, when the pressing on the button 55 is not executed, the control unit 12 returns the process to step 203.

  Next, in step 205, the playback position of the moving image data being played back at the time when the button 55 was pressed in step 204 is specified. Then, the control unit 12 sets a break at the specified playback position, and proceeds to the next step 206. That is, the image information displayed on the image reproduction unit 50 at the time when the button 55 is pressed is specified, and the specified image information and the incidental information related to the image information are replaced with new delimiter information (second Set as delimiter information).

  Here, on the reproduction time axis of the moving image data, another segment is always set before the segment set at this time. For example, if the process of this step 204 is a process related to the first press on the button 55, the first set in step 202 before the break set at this time on the playback time axis of the moving image data. There is a break. Further, for example, it is assumed that the process in step 204 is a process related to the second press on the button 55. In this case, on the playback time axis of the moving image data, before the break set at this time, there is a break related to the first press on the button 55 set in step 204 executed before the processing.

  Therefore, this process generates a section on the playback time axis on the moving image data. Note that if the processing of this step 204 is processing related to the first pressing on the button 55, the generated section is the first section in FIG. Further, if the processing of this step 204 is processing related to the second press on the button 55, the generated section is the second section in FIG.

  Next, in step 206, the control unit 12 analyzes the incidental information associated with the image information included in the section generated by the delimiter setting in step 205. And the control part 12 acquires the driving | running | working information about this produced | generated area by the said analysis.

  In this embodiment, as shown in FIG. 1, the image information and supplementary information included in a section are separated from the playback position of the section indicating the start of the section, and immediately before the playback position of the section indicating the end of the section. This is image information and incidental information existing up to the reproduction position. In other words, the travel information in the section is based on the image information included in the second delimiter information from the image information included in the first delimiter information, and the incidental information related to the image information. Generated. The image information and supplementary information existing at the playback position at the end indicating the end of the section may be included in the section, or may not be included as in the present embodiment.

  Here, the delimiter indicating the start of the section in this process is the delimiter set immediately before on the reproduction time axis of the delimiter set by the present process. Further, the break indicating the end of the section is a break set by this process. In other words, the control unit 12 exists from the playback position of the segment set immediately before the segment set by this process to the playback position immediately before the segment playback position set by this process. Image information and incidental information are specified as image information and incidental information included in the section generated by this processing.

  The control unit 12 analyzes the incidental information associated with the image information specified as described above, and acquires travel information about the generated section. The travel information about the acquired section includes vehicle movement characteristics. For example, the section required time, the average speed, the maximum speed, the minimum speed, the travel distance, and the average acceleration (average G value) in the section. , Maximum acceleration (maximum G value), minimum acceleration (minimum G value), and the like. Note that the control unit 12 may be configured to acquire all of these pieces of information as travel information for the section, or may be configured to acquire only predetermined information.

For example, among the supplementary information associated with the image information included in the generated section, the control unit 12 includes the supplementary information associated with the image information with the reproduction position closest to the reproduction information, and the image with the reproduction position behind. The section required time is obtained from the incidental information associated with the information. Specifically, the control unit 12 obtains the section required time by obtaining the difference between the times obtained by the timer circuit 25 included in these two incidental information. Of the image information included in the generated section in this process, the image information with the playback position closest to the playback position is the segment set immediately before the segment set by this process on the playback time axis. This is image information existing at the reproduction position. The image information with the playback position at the back is the image information existing at the playback position immediately before the playback position of the break set by this processing. That is, the section required time is included in the time information included in the incidental information associated with the image information included in the first delimiter information and in the incidental information associated with the image information included in the second delimiter information. It is obtained from the difference with the time information.

  Further, when the image information is acquired at a predetermined time interval (a constant same time interval), the section required time can be proportional to the number of image information included in the section. Therefore, in this case, the control unit 12 may calculate the section required time from the number of image information included in the generated section.

  Moreover, the control part 12 calculates | requires the average speed in the area using the incidental information linked | related with all the image information contained in an area, for example. For example, the control unit 12 acquires speed information obtained by the vehicle speed sensor 81 from the incidental information associated with each piece of image information included in the section. And the control part 12 calculates the average speed in this area by calculating | requiring the average of the acquired traveling speed. Specifically, the control unit 12 divides the sum of the acquired speed information by the number of acquired speed information (the number of image information), thereby calculating average speed information that is an average value of the speed information in the section. Is calculated. The average acceleration in the section can be explained similarly.

  Further, for example, the control unit 12 identifies the speed information having the largest value from the speed information (accompanying information) associated with the image information included in the generated section, thereby determining the maximum speed in the section. Ask. The maximum acceleration (maximum G value) in the section can be explained similarly.

  Further, the control unit 12 specifies, for example, speed information having the smallest value from the speed information (accompanying information) associated with the image information included in the generated section, thereby determining the minimum speed in the section. Ask. The minimum acceleration (minimum G value) in the section can be explained similarly.

  Further, for example, the control unit 12 obtains the travel distance in the section using the incidental information associated with all the image information included in the section. For example, the control unit 12 acquires speed information obtained by the vehicle speed sensor 81 from the incidental information associated with each piece of image information included in the section. And the control part 12 calculates | requires the sum of the acquired speed information. Further, the control unit 12 multiplies the sum by a proportional constant determined by the acquisition frequency of the image information. Thereby, the control unit 12 can calculate the travel distance.

  Note that a travel position may be acquired as travel information. In this case, for example, among the incidental information associated with the image information included in the generated section, the control unit 12 includes the incidental information associated with the image information with the reproduction position closest to the reproduction information, and the reproduction position with the rearmost position. The travel distance may be calculated from the incidental information associated with the image information. Specifically, the control unit 12 may calculate the travel distance by obtaining a difference between travel positions included in these two additional information.

The control unit 12 acquires travel information about the section thus generated. And the control part 12 will return a process to step 203, as FIG. 6 shows, if the driving information about this area is acquired.

  As illustrated in FIG. 6, the control unit 12 repeats the processing from step 203 to step 206 until the second pressing of the button 54 is executed. Thereby, a delimiter can be set between the first delimiter and the last delimiter. In step 203, when the second press on the button 54 is executed, the control unit 12 ends the repetition and proceeds to step 207.

FIG. 9 shows the display 6 after the first press on the button 54 (FIG. 8) and before the second press on the button 54 is executed five times. An example of the screen displayed is shown below. As shown in FIG. 9, the playback position of the break associated with pressing the i-th time (i = 1, 2, 3, 4, 5) with respect to the button 55 is indicated by the icon “i”. A section between icons “S” and “1” is the first section shown in FIG. At this point, between “S” and “1”, between “1” and “2”, between “2” and “3”, between “3” and “4”, and “4” A total of five sections between “5” are generated.

  Next, in step 207, the control unit 12 specifies the playback position of the moving image data that is being played back when the second press of the button 54 in step 203 is executed. Then, the control unit 12 sets the last break at the specified playback position, and proceeds to the next step 208.

  When the processing in step 207 is executed, a section is generated on the playback time axis on the moving image data for the same reason as in step 205. Specifically, a section is generated between the first partition or a partition set by pressing the button 55 and the last partition.

  Finally, in step 208, the control unit 12 analyzes the incidental information associated with the image information included in the section generated by the delimitation setting in step 207. And the control part 12 acquires the driving | running | working information about this produced | generated area by the said analysis. That is, the image information displayed on the image reproduction unit 50 at the time when the button 54 is pressed for the second time is specified, and the specified image information and the incidental information related to the image information are separated from each other (n-th information). Information). In this embodiment, n = 7. This process is the same as step 206.

  At this time, the control unit 12 acquires the total time in the time region in which the section is set. The total time in the time region in which the section is set is the time between the playback position where the first segment is set and the playback position where the last segment is set. The control unit 12 includes the time information obtained by the clock circuit 25 included in the auxiliary information associated with the image information existing at the reproduction position where the first division is set, and the reproduction position where the last division is set. The total time is acquired by obtaining a difference between the time information obtained by the timer circuit 25 included in the incidental information associated with the image information to be performed. That is, the total time is included in the time information included in the incidental information associated with the image information included in the first delimiter information and the incidental information associated with the image information included in the nth delimiter information. It is obtained from the difference from the current time information. In this embodiment, n = 7.

  Thereby, the information processing apparatus 1 ends the process for setting the section and acquiring the travel information for the section.

  FIG. 10 shows an example of a screen displayed on the display 6 when the process of step 208 is executed. At the time of FIG. 9, five sections were generated. FIG. 10 shows an example in which a second press on the button 54 is executed after FIG. 9.

  In the screen example shown in FIG. 10, the playback position of the last segment set by the second pressing of the button 54 is indicated by an “E” icon. Further, at this time point, travel information on the section is acquired for all sections generated on the reproduction time axis of the moving image data. Further, the total time in the time region in which the section is set is also acquired. Therefore, in the screen example shown in FIG. 10, the in-section travel information display unit 53 displays the travel information for the entire time and section. In the example of the screen shown in FIG. 10, the section required time and the average speed in the sixth section are displayed as the travel information for the section.

  At this time, when the button 56 is pressed by the operation of the operation device 5 by the user, the travel information about the section acquired in all the sections reproduced on the reproduction time axis of the moving image data is displayed in a list. FIG. 11 shows an example of a screen displayed on the display 6 when the button 56 is pressed after the time shown in FIG. As shown in FIG. 11, the list display unit 64 displays a list of travel information about the sections acquired in all sections reproduced on the reproduction time axis of the moving image data. In the example of the screen shown in FIG. 11, the section required time and average speed in the section are displayed as an example of the travel information for the section.

  In Steps 201, 203, and 204, the operation in which the control unit 12 accepts pressing of the button 54 or the button 55 or accepts a user operation related to the equal section setting to be monitored corresponds to the operation of the operation accepting unit 121. . In Steps 206 and 208, the operation of the analysis processing for the incidental information of the section generated by the control unit 12 corresponds to the operation of the intra-section traveling information acquisition unit 122. Further, in step 202 and subsequent steps, the operation in which the control unit 12 generates the display image illustrated in FIGS. 7 to 11 corresponds to the operation of the display processing unit 123.

§4 Actions and effects according to the embodiment As described above, in the information processing apparatus 1 according to the present embodiment, sections on the reproduction time axis of the moving image data recorded by the drive recorder 2 by accepting an operation by the user. Is set. Then, based on the incidental information associated with the image information included in the section, traveling information about the section is acquired.

  Therefore, according to the present embodiment, the travel information about the section set by the operation by the user is acquired, so the travel about the arbitrary section desired by the user from the moving image data recorded during the movement of the moving body. Information can be acquired.

  The user can utilize the information processing apparatus 1 according to the present embodiment in various scenes.

  For example, it is assumed that the user drives the vehicle and makes a round run that runs a plurality of times on the same route such as a circuit. Then, it is assumed that the user has recorded the pattern of the traveling around with the drive recorder 2. At this time, by using the information processing apparatus 1 according to the present embodiment, the user grasps the lap time (section required time), the travel speed variation, the travel distance, the generated G value, and the like in each lap of the circular travel. Is possible. Thereby, the user can determine whether the driving is good or bad on each round of the round trip.

Further, for example, by using the information processing apparatus 1 according to the present embodiment, the user can grasp the section required time, the generated G value, and the like when traveling on a straight line, a corner, and a hairpin curve. These pieces of information are useful for driving and maintenance.

  Further, for example, it is assumed that the user has driven the vehicle and traveled between the same starting point and the same destination using different routes. Then, it is assumed that the user has recorded a running pattern when each path is used by the drive recorder 2. At this time, the user can grasp the maximum speed, the maximum acceleration, and the like in each path by using the information processing apparatus 1 according to the present embodiment. Thereby, the user can determine whether each path is good or bad based on these pieces of information.

§5 Modifications Embodiments of the present invention have been described in detail above. However, the above description is merely an example of the present invention in all respects and is not intended to limit the scope thereof. It goes without saying that various improvements and modifications can be made without departing from the scope of the present invention.

  For example, in the display screen examples of FIGS. 7 to 11, the breaks and sections set on the playback time axis of the moving image data are displayed on the playback bar 61. However, for example, it may be displayed on the graph display unit 63 as in the display screen example of FIG. FIG. 12 shows an example in which breaks and sections set on the playback time axis of moving image data are displayed on the graph display unit 63.

  For example, the incidental information may include position information at the time when the incidental information is acquired. In this case, for example, by using the position information, the control unit 12 displays the position of the vehicle at the time when the image information existing at the segmented reproduction position set on the reproduction time axis of the video data is acquired A map to be generated may be generated and displayed on the display 6. FIG. 13 shows an example of a map image that displays the position of the vehicle at the time when the image information that exists at the segmented playback position set on the playback time axis of the moving image data is acquired.

  At this time, map information for generating a map is required. For example, the control unit 12 generates a display screen as shown in FIG. 13 using map information stored in the storage unit 11 or acquired via a network.

  Further, for example, the setting of the section in the moving image data may be realized by providing a range for speed, acceleration, position information or the like instead of on the reproduction time axis. Note that providing a range for speed, acceleration, position information, or the like can be explained in the same manner as setting a section (range) on the playback time axis.
