Description

  The present invention relates to an image recording apparatus and an image recording method.

  2. Description of the Related Art Conventionally, a recording apparatus that captures and records an image around a vehicle while the vehicle is traveling, so-called a drive recorder, has been widely used. The drive recorder records a moving image taken by a camera on a nonvolatile internal recording medium, thereby enabling verification of an accident or the like that occurs during traveling.

  As a method for recording a moving image on an internal recording medium, an event recording method for performing recording when an accident occurs in the host vehicle and a constant recording method for performing constant recording are known. In the former, when the acceleration sensor senses that an impact has been applied to the vehicle such as a collision or sudden braking, and it is determined that an accident has occurred, it records images and driving information data for several tens of seconds before and after the sensing. . The latter reads data from the RAM at a predetermined cycle and records it on the internal recording medium. In any method, when recording is repeated, a large number of moving images are recorded in the internal recording medium. Therefore, when the user uses the moving images, thumbnail images of the moving images are displayed as a list. The user can select a moving image to be used by viewing the thumbnail image.

  In relation to the above, in Patent Document 1, the captured image data is associated and registered in the database of the server, and the terminal downloads image data, thumbnails, position data, and map data from the server, and the position data An image data registration / reproduction method for displaying marker information indicating a shooting position of an image on an electronic map based on the map data and displaying a thumbnail of the image paired with the marker information is disclosed.

JP 2002-278993 A JP 2004-363823 A JP 2007-323543 A JP 2009-130379 A JP 2010-171838 A JP 2011-009846 A JP 2000-196933 A JP 2001-304873 A JP 2011-247831 A

  In the case of the above-described image data registration / reproduction method, the thumbnail displayed to select image data to be used is obtained by reducing captured image data. However, in the case of a drive recorder, since the angle and position of the photographing apparatus are fixed, the photographed image always has almost the same composition. For this reason, when thumbnails with reduced image data are displayed in a list, they all look the same and cannot be used as a reference for selection.

  Further, in Patent Document 1, since position information indicating the position where image data is captured is displayed, an area for displaying position information is secured separately from the thumbnail of image data, and there is a problem that simple display is not possible. is there.

  The present invention has been made to solve such a problem, and its purpose is to capture a list of thumbnail images of a plurality of moving images taken while the vehicle is running, and to capture the images. It is possible to provide a technique for improving the convenience when the user browses the moving image, and the contents can be simply indicated by the thumbnail image.

In order to solve the above problems, the present invention employs the following means. That is, the imaging apparatus of the present invention
A storage control unit that acquires a moving image obtained by imaging the periphery of the vehicle from an imaging device mounted on the vehicle and stores the moving image in a storage device;

[Recording method]
6 and 7 are explanatory diagrams of a recording method in the drive recorder system according to the present embodiment. Hereinafter, a moving image recording method in the drive recorder system according to the present embodiment will be described with reference to FIGS. 6 and 7.

  When the user turns on the ignition switch to start the vehicle engine, the ACC power supply is turned on and power is supplied to the drive recorder system 1. The drive recorder system 1 performs the processing shown in FIGS. 6 and 7. Execute. First, the drive recorder 100 newly creates a thumbnail file. Here, creating a new thumbnail file means creating an empty image file as a thumbnail file, creating a record of a database that manages the thumbnail file, and identification information and file name for managing the thumbnail file. For example.

  Further, the drive recorder 100 acquires a moving image captured by the imaging device 300 via the main memory 110, and starts recording the moving image by sequentially starting storage in the data storage 200 (step S20).

  Next, the drive recorder 100 obtains information such as the vehicle running data, the thumbnail name (bitmap name) generated in step S10, and the moving image file name (moving image name) from the thumbnail parent database (hereinafter simply referred to as the parent DB). (Also referred to as “also”) is registered in the record of the thumbnail (step S30). FIG. 8 is a diagram illustrating an example of a database that stores information related to thumbnails. The parent DB 51 in FIG. 8 is a database that stores information for each thumbnail. In the parent DB 51, the thumbnail ID is identification information for identifying a thumbnail and associating it with information in the child DB 52. The longitude / latitude is position information indicating a traveling position of the vehicle (hereinafter, also referred to as an imaging position) when a moving image corresponding to the thumbnail is captured. The time is information indicating the date and time when a moving image corresponding to the thumbnail is captured. In FIG. 8, the longitude / latitude and time are the position and time at the start of moving image capturing. However, the present invention is not limited to this. Good. The area (imaging area) is information indicating an area to which the imaging position belongs among arbitrarily divided areas such as prefectures and municipalities.

  After step S30, the drive recorder 100 newly creates a record of the thumbnail in the child thumbnail database (hereinafter also referred to as child DB) 52 (step S40). The child DB 52 in FIG. 8 is a database that stores information (child thumbnail data) every predetermined time. In the child DB 52, the child ID is identification information for identifying the child thumbnail data and associating it with the information in the parent DB 51. The longitude / latitude is position information indicating the traveling position of the vehicle (hereinafter also referred to as a child imaging position) every predetermined time. The time is information indicating the current date and time, in other words, the date and time when the vehicle was present at the child imaging position. The screen x coordinate and the screen y coordinate are information indicating coordinates on the screen corresponding to the child imaging positions when thumbnails are displayed on the display device 400.

  The drive recorder 100 determines whether there is external information acquired by the external information acquisition unit 16. When it is determined that there is external information (step S50, Yes), the drive recorder 100 writes the external information to a storage unit such as the main memory 110. If the external information is information indicating an event at the child imaging position of the child thumbnail data created in step S40, such as traffic jam information or information indicating that there is a broken vehicle, the external information may be stored in the child thumbnail data record. Good.

  On the other hand, when it is determined in step S50 that there is no external information (No in step S50), the drive recorder 100 skips step S60 and proceeds to step S70.

  In step S70, the drive recorder 100 determines whether or not the length of the moving image, that is, the recording time of the moving image has reached a predetermined time (20 minutes in FIG. 6). The predetermined time can be arbitrarily set such as 15 minutes or 30 minutes.

  If it is determined in step S70 that the predetermined time has been reached (step S70, Yes), the drive recorder 100 registers child thumbnail data such as latitude / longitude and time at the child imaging position in the child DB 52 (step S90). In addition, the drive recorder 100 closes the thumbnail and stores it in the data storage 200 (step S100). Further, the drive recorder 100 completes the recording of the moving image, closes the moving image file, stores it in the data storage 200 (step S110), and returns to step S10.

  On the other hand, if it is determined in step S70 that it has not reached 20 minutes, the drive recorder 100 determines whether or not the elapsed time since the creation of the child thumbnail data has reached a predetermined time (1 minute in FIG. 6). In other words, it is determined whether or not the time interval for creating the next child thumbnail data has been reached (step S80). The predetermined time can be arbitrarily set such as 2 minutes or 30 seconds.

  If it is determined in step S80 that the elapsed time has reached the predetermined time (step S80, Yes), the drive recorder 100 returns to step S40 and creates the next child thumbnail data. On the other hand, when it is determined that the elapsed time has not reached the predetermined time (step S80, No), the drive recorder 100 proceeds to step S120.

  In step S120, drive recorder 100 determines whether or not the user has stopped the engine of the vehicle. This determination may determine whether or not the ACC power supply is turned off. Here, when it determines with the engine not being stopped (step S120, No), it returns to step S80. Moreover, when it determines with the engine having been stopped (step S120, Yes), it transfers to step S130 of FIG.

  In step S130, the drive recorder 100 registers child thumbnail data such as latitude / longitude and time at the child imaging position in the child DB 52. Further, the drive recorder 100 closes the thumbnail and stores it in the data storage 200 (step S140). Furthermore, the drive recorder 100 completes the recording of the moving image, closes the moving image file, and stores it in the data storage 200 (step S150).

Next, the drive recorder 100 maps the map information around the imaging position from the database 120, for example, a rectangular range including all the child imaging positions, and each side of the rectangular map and the closest child imaging position. Map information in a range where the interval is a predetermined value is acquired (step S160). That is, the child imaging position does not fit on the map, and the path does not protrude from the thumbnail, and the distance between the child imaging position closest to each side of the map and each side is not too large so that the path does not become small. In addition, map information in a range where the route is superimposed with an appropriate size is acquired. Moreover, the drive recorder 100 shows a path | route on a map by drawing the mark which shows each child imaging position on the map which this map information shows (step S170). This path may be a dot-like display indicating each child imaging position or a line-like display in which each child imaging position is connected by a line. For example, in the thumbnail 41 of FIG.

  Then, when the drive recorder 100 draws a mark indicating each child image pickup position on the map and displays the mark as a thumbnail on the display device 400, coordinates on the display screen on which the mark indicating each child image pickup position is displayed ( The screen x coordinate / screen y coordinate) is obtained and registered in the child DB 52 (step S180).

  Further, the drive recorder 100 draws the external information written in step S60 on the map (step S190). A specific display form of the external information will be described later.

  After step S190, the drive recorder 100 closes the thumbnail and stores it in the data storage 200 (step S200). Further, the drive recorder 100 completes the recording of the moving image, closes the moving image file, stores it in the data storage 200 (step S210), and ends the processing of FIGS.

  When moving images and thumbnails are stored in the data storage 200 as described above, and a list of moving images stored in the data storage 200 is displayed for the user to use moving images, the drive recorder 100 For example, as shown in FIG. 4, an image obtained by superimposing a travel route of a vehicle on a map can be used as a thumbnail, and a plurality of thumbnails can be displayed on the display device 400 as a list.

  As a result, it is possible to simply indicate in a thumbnail which route the content of each moving image is when traveling, and to improve convenience when the user uses the moving image. it can. Note that the device for displaying moving images and thumbnails is not limited to the drive recorder 100, and may be another device. In this case, for example, the drive recorder 100 creates a thumbnail and stores it in the data storage 200 in the same format as the thumbnail temporary file used by the OS (Operating System) of the other device. When a list in the storage 200 is displayed, a list of thumbnails in which the travel route of the vehicle is superimposed on a map can be displayed based on the temporary file.

[Example of thumbnail display format]
When displaying a list of thumbnails, the operation / display control unit 101 of the drive recorder 100 displays a slide bar in the display screen and scrolls the thumbnails if there are more thumbnails than can be displayed on the display screen of the display device 400. It may be possible.

  FIG. 9 is a diagram showing an example in which an up / down slide bar is displayed, and FIG. 10 is a diagram for explaining a scrolling operation. In FIG. 9, a slide bar 61 is displayed at the right end of the display screen of the display device 400. By moving the slide bar 61 up and down, the user can scroll the thumbnails displayed on the display screen and display the thumbnails that could not be displayed on the display screen.

As shown in FIG. 10, the upper and lower positions of the slide bar 61 correspond to the positions of the thumbnails displayed on the display screen. In FIG. 10, for easy identification of each thumbnail, No. 1-No. A number 12 is schematically shown. In the example of FIG. 10, a total of six thumbnails are displayed on the display screen of the display device 400 in three columns and two rows.
There are 6 thumbnails, so 6 thumbnails are not displayed. In FIG. 10B, the slide bar 61 is located at the center in the vertical direction. 1-No. Of the 12 thumbnails, the center No. 4-No. Up to 9 are displayed. Compared with FIG. 10 (B), when the slide bar 61 is moved upward as shown in FIG. 10 (A), the thumbnail is scrolled so that the thumbnail moves relatively downward, and the upper No. 1-No. 3 thumbnails are displayed. Also, compared to FIG. 10B, when the slide bar 61 is moved downward as shown in FIG. 10C, the thumbnail is scrolled so that it moves relatively upward, and the lower No. 10-No. Twelve thumbnails are displayed.

  FIG. 11 is a diagram illustrating an example in which left and right slide bars are displayed, and FIG. 12 is a diagram illustrating a scrolling operation. In FIG. 11, a slide bar 62 is displayed at the lower end of the display screen of the display device 400. The user can move the slide bar 62 up and down to scroll the thumbnails displayed on the display screen and display the thumbnails that could not be displayed on the display screen.

  As shown in FIG. 12, the left and right positions of the slide bar 62 correspond to the positions of thumbnails displayed on the display screen. In the example of FIG. 12, a total of six thumbnails are displayed on the display screen of the display device 400 in three columns and two rows. However, since there are twelve thumbnails, six thumbnails are not displayed. In FIG. 12B, the slide bar 61 is located slightly to the right of the center in the left-right direction. 1-No. Of the 12 thumbnails, no. 4-No. 6, no. 7-No. 9 is displayed. Compared with FIG. 12 (B), when the slide bar 62 is moved to the left as shown in FIG. 12 (A), the thumbnail is scrolled so as to move relatively to the right. 2, no. Eight thumbnails are displayed. Also, compared to FIG. 12B, when the slide bar 62 is moved to the right as shown in FIG. 12C, the thumbnail is scrolled so as to move relatively to the left. 6, no. Twelve thumbnails are displayed.

  The method of scrolling the thumbnail is not limited to displaying the scroll bar, but the user touches the display screen with a finger and slides the finger to move the thumbnail in the finger moving direction to scroll. There may be.

  Further, the drive recorder 100 may select the number to be displayed on one screen of the display device 400. FIG. 13 is an explanatory diagram of an operation for selecting the number of thumbnails to be displayed on one screen.

  FIG. 13A shows a state in which four thumbnails are displayed on one screen of the display device 400. In this state, the user touches the display screen with a plurality of fingers to increase the interval between the fingers, so-called pinch. When the “out” operation is performed, the thumbnail is displayed in a large size, and the number of thumbnail images displayed on one screen is reduced. In the example of FIG. 13B, one thumbnail is displayed.

  In addition, as shown in FIG. 13C, in a state where four thumbnails are displayed on one screen of the display device 400, the user touches the display screen with a plurality of fingers to reduce the interval between the fingers, so-called pinch-in operation. When this is done, the thumbnails are displayed in a small size, and the number of thumbnail images displayed on one screen is increased. In the example of FIG. 13D, six thumbnails are displayed.

FIG. 14 is a diagram illustrating an example in which a departure point and an arrival point are displayed on a thumbnail map. For example, the thumbnail generation unit 105 obtains, as a starting point, a position where the engine is started or a position where the ACC power is turned on in the route 69 shown based on the travel data, and a balloon 63 indicating the starting point. And the mark 64 are drawn at corresponding positions on the map. In addition, the thumbnail generation unit 105 obtains, for example, a position where the engine is stopped or a position where the ACC power is turned off as an arrival point based on the travel data, and generates a balloon 65 or a mark 66 indicating the arrival point. Draw at the corresponding location on the map. The shapes of the balloons 63 and 65 and the marks 64 and 66 are not particularly limited, and can be arbitrarily set. For example, the marks 64 and 66 may be a pin, a house, a flag, S (start), G (goal), or the like. When the user sets a departure point and a destination point (arrival point) for the navigation control unit 102, information indicating the departure point and the destination point (arrival point) may be acquired from the navigation control unit 102.

  FIG. 15 is a diagram illustrating an example of displaying a passing point on a thumbnail map. For example, the thumbnail generation unit 105 obtains, as a passing point, an end portion that is not a starting point and an arriving point in the route 70 obtained based on the travel data, and displays a balloon 67 indicating the passing point on a corresponding position on the map. To draw.

  FIG. 16 is a diagram illustrating an example of displaying thumbnails grouped by category. The drive recorder 100 can display thumbnails by grouping them into categories. For example, when the grouping display is selected by the user, the thumbnails are grouped and displayed as shown in FIG. 16, and the grouping display is selected. If not, thumbnails are displayed as a list without being grouped as shown in FIG.

  FIG. 16A illustrates an example in which the areas are grouped and displayed, such as the Osaka area and the Nagoya area. When the grouped display is selected, for example, the operation / display control unit 101 refers to the child DB 52 for each thumbnail, and the traveling position (child imaging position) indicated by the latitude / longitude of the child thumbnail data is the prefecture or Which area is located in a predetermined section such as a municipality is determined, and thumbnails that match this area, that is, a category, are displayed as one group. It should be noted that thumbnails whose child imaging positions indicated by the child thumbnail data match a plurality of categories may belong to a plurality of categories, or belong to one category selected based on the child imaging positions at the start of imaging. It may be a thing.

  Here, the operation / display control unit 101 displays the thumbnail of the group together with the name of each area, such as the Osaka area and the Nagoya area. The thumbnail of a group may be a thumbnail of moving images belonging to the group, or may be generated according to a thumbnail belonging to the group. For example, by acquiring the child imaging positions of thumbnails belonging to a group, acquiring map information of a range including all the child imaging positions, and marking the locations corresponding to the imaging positions of the thumbnails on this map 6. Similar to the processing of FIG. 7, a thumbnail of the group whose route is marked on the map is generated.

  FIG. 16C shows an example in which moving images are grouped and displayed for each day when they are captured. In this case, for example, with respect to each thumbnail, the operation / display control unit 101 refers to the child DB 52, obtains the imaged date from the time of the child thumbnail data, and collects the imaged date, that is, the thumbnail that matches the category as one group. Display as. In the example of FIG. 16 (C), grouping is performed for each day when moving images are captured, but in addition, grouping is performed for each category based on date and time such as week, month, season, time zone such as morning / day / night, and day of the week. May be performed.

  The category for grouping is not limited to area and date / time, but may be weather, driver, new route or existing route, and the like. For example, when grouping by weather, when capturing images, weather information is acquired from an external device 950 that provides weather information and stored in the child DB 52 as child thumbnail data. Thumbnails with matching information are grouped together.

  When grouping by a driver (user), when imaging, who is the driver is identified as driver information, and this driver information is stored in the child DB 52 as child thumbnail data. The thumbnails that match the driver information are grouped into one group.

  As a method for identifying the driver, for example, a user terminal such as a smartphone connected to the drive recorder 100 during driving is registered in the database 120 in association with the driver, and the drive recorder 100 is connected during imaging. The user terminal is identified to identify the driver, and the driver information indicating the driver is stored in the child DB 52 as child thumbnail data. Not only this, the camera which image | photographs a driver | operator is installed in the vehicle, The drive recorder 100 identifies the image | photograph of the driver | operator image | photographed with the camera in a vehicle during imaging of the moving image by the imaging device 300, and a driver | operator. The driver information indicating the driver may be stored in the child DB 52 as child thumbnail data.

  As a method for identifying whether a new route or an existing route, for example, the drive recorder 100 stores, in the database 120, nodes and links in map information corresponding to intersections and roads that have passed during traveling of the vehicle as traveling history. In addition, during the capturing of the moving image, the travel position information indicating the link or node of the current travel position is acquired from the navigation control unit 102, and if this travel position information is included in the travel history, the existing route, If the travel position information is not included in the travel history, it is determined as a new route. Then, information indicating whether the route is a new route or an existing route is stored in the child DB 52 as child thumbnail data.

  In addition, when displaying the group thumbnails, the operation / display control unit 101 displays a plurality of thumbnails arranged side by side as shown in FIGS. 16 (A) and 16 (C). The number of thumbnails displayed side by side corresponds to the number of moving images belonging to the group. That is, when a group of thumbnails is displayed as being arranged in a large number, there are a large number of moving images belonging to the group, and when a group of thumbnails displayed in a line is a small number, It shows that there are a small number of moving images belonging to. Thus, the user can intuitively grasp the amount of moving images belonging to each group. It should be noted that the thumbnails of the groups displayed in a line and the number of thumbnails belonging to the group need not exactly match.

  When any one of a plurality of groups displayed on the display device 400 is selected as shown in FIGS. 16A and 16C, thumbnails of moving images belonging to the selected group are displayed. A list is displayed as shown in FIG.

  Thus, when using a moving image, the user can display thumbnails by narrowing down by category, so that it becomes easy to find a target moving image and convenience is improved.

  FIG. 17 is a diagram illustrating an example in which the travel route displayed on the thumbnail is a specific color. When the route is displayed in a line, the thumbnail generation unit 105 draws the route line in a specific color different from the other lines so that it can be distinguished from other lines indicating roads on the map. In FIG. 17, a line 68 indicates a route. In FIG. 17, for the sake of convenience, the difference in color is indicated by the difference in density. In addition, in FIG. 17, the route is displayed in a specific color, but in addition to this, the shape of a line such as a dotted line or a dash-dot line, the type of the line thickness, etc. are determined, and the route is displayed with a specific type of line. It may be drawn so that it can be distinguished from other lines.

FIG. 18 is a diagram illustrating an example in which external information acquired by VICS is displayed in a thumbnail. In FIG. 18, a traffic jam location 72 in the travel route 71 is displayed with a thicker line than a traffic jam location. In addition, you may show a traffic congestion location not only with the thickness of a line but with the color of a line, or blinking.

  In FIG. 18, lane regulation information 73 and broken vehicle information 74 are displayed in a balloon.

  For example, in step S190 of FIG. 7, the thumbnail generation unit 105 draws the external information acquired by VICS on the map as shown in FIG.

  This allows the user to grasp the VICS information on the thumbnail, so if the video you want to use is in a traffic jam or if it was taken immediately after looking at the broken car It becomes possible to search by relying on VICS information.

  FIG. 19 is a diagram illustrating an example in which a route when traveling on a highway is displayed in a specific color. The thumbnail generation unit 105 draws a line of a route traveling on the highway in a specific color so that the user can distinguish between a route traveling on the highway and a route traveling on a general road. In FIG. 19, in the route 71, the highway driving point 75 is displayed in a different color from the general road driving point 76. In FIG. 19, for the sake of convenience, the difference in color is indicated by the difference in density. Further, the route may be displayed in a color determined for each type of road, such as a motorway or a one-way road, as well as an expressway.

  FIG. 20 is a diagram showing an example in which thumbnails of places where sudden braking or sudden acceleration has been performed are displayed. The drive recorder 100 periodically acquired the detected value of the acceleration sensor, the vehicle speed pulse, the brake operation information, and the accelerator operation information during traveling, and sudden braking or acceleration was performed based on these information. Is detected. For example, when braking is applied and acceleration during deceleration exceeds a predetermined value, or when the amount of decrease in vehicle speed per unit time exceeds a predetermined value, it is determined that sudden braking has been performed and indicates sudden braking. Information is stored in the child DB 52 as child thumbnail data. In addition, when the accelerator operation amount exceeds a predetermined value and the acceleration exceeds a predetermined value or the increase amount of the vehicle speed per unit time exceeds the predetermined value, it is determined that the rapid acceleration has been performed, and the rapid acceleration is performed. The indicated information is stored in the child DB 52 as child thumbnail data.

  For example, when information on sudden braking or sudden acceleration is recorded in the child thumbnail data in step S170 of FIG. 7, the thumbnail generating unit 105, together with route information, shows a sign indicating sudden braking (sudden braking mark) or sudden braking. A mark indicating acceleration (rapid acceleration mark) is drawn on the map.

  In FIG. 20, a sudden brake mark 77 and a sudden acceleration mark 78 are shown on the path 71 in a shape that calls attention. The shapes of the sudden brake mark 77 and the sudden acceleration mark 78 are not limited to this.

  FIG. 21 is a diagram showing an example in which weather information is added to the thumbnail. The drive recorder 100 acquires a weather map from an external device 950 that provides weather information, and generates a thumbnail by superimposing a portion of the weather map whose time coincides with the thumbnail imaging position on the map.

  In FIG. 21, the thumbnail 81 superimposes on the map an image in the same range 83 as the map used for the thumbnail 81 in the 14:30 weather map 82 at which the captured times coincide. Also, the thumbnail 84 superimposes an image of the same range 86 as the map used for the thumbnail 84 on the map of the 17:30 weather map 85 having the same imaged time.

Since the weather map often has a time lag before being provided, the drive recorder 100 generates a thumbnail in the process of FIGS. 6 and 7 and then superimposes the weather map when the weather map is acquired. To update the thumbnail.

  FIG. 22 is a diagram illustrating an example in which information such as an accident is added to the thumbnail. The drive recorder 100 acquires event information from an external device 950 that provides event information such as an accident, a fire, and a parade, and draws an event whose time coincides with the thumbnail child imaging position on the map. The determination of whether or not the thumbnail imaging position matches the event location is not limited to a complete match, and the event location is within a predetermined range, such as within 1 km of the thumbnail child imaging position. If it is located, it is determined to match. The determination of whether or not the thumbnail imaging time matches the event time is not limited to a complete match, and the event occurrence time is within a predetermined range such as within 15 minutes before and after the thumbnail imaging time. If it is within, it is determined to match.

  In the example of FIG. 22, the event mark 88 is drawn at the position of 15:00 Amagasaki where the imaging time of the thumbnail 87 matches the time in the event information such as 13:00 Kobe, 14:00 Amagasaki, 15:00 Amagasaki. Yes.

  Since the event information often has a time lag before being provided, the drive recorder 100 draws an event mark when the event information is acquired after generating the thumbnail in the processing of FIGS. 6 and 7. To update the thumbnail.

  FIG. 23 is a diagram illustrating an example in which information indicating that a mail has been transmitted / received is added to the thumbnail, and FIG. 24 is a diagram illustrating an example in which information indicating that a call has been transmitted / received is added to the thumbnail. The drive recorder 100 acquires information (hereinafter also referred to as transmission / reception information) indicating that mail or telephone has been transmitted / received from the connected user terminal, and registers this transmission / reception information in the child DB 52 as child thumbnail information.

  Then, for example, in step S190 of FIG. 7, the thumbnail generation unit 105 indicates that the transmission / reception information has been transmitted / received on the thumbnail path 71 according to the child imaging position of the child thumbnail data in which the transmission / reception information is registered (transmission / reception mark). Draw.

  In FIG. 23, a transmission / reception mark 91 indicates that the user has sent a mail to XX, and a transmission / reception mark 92 indicates that the user has received a mail from ΔΔ.

  In FIG. 24, a transmission / reception mark 93 indicates that the user has made a call to XX, and a transmission / reception mark 94 indicates that the user has received a call from ΔΔ.

  As a result, the user can grasp the transmission / reception information on the thumbnail, so this transmission / reception information can be used when the moving image that the user wants to use is on the phone or was captured immediately after sending the mail. It becomes possible to look for it with confidence.

  FIG. 25 is a diagram illustrating an example in which information based on the date and time is displayed on the thumbnail. The drive recorder 100 refers to the parent DB and displays a thumbnail frame 95 in a color corresponding to the time of each thumbnail. For example, the day of the week, the time zone, and the color based on the date and time are set in advance, such as red for holidays and black for weekdays. The frame generation unit 105 may draw the frame 95 in the thumbnail, or the operation / display control unit 101 may display the frame 95 around the thumbnail.

  Thereby, it is possible to grasp whether the user has taken a picture on a holiday or a picture taken on a weekday by the color of the thumbnail frame 95, and the convenience is improved.

  FIG. 26 is a diagram showing an example of thumbnails taken in the daytime and thumbnails taken in the nighttime, and FIG. 27 is a thumbnail of moving images taken at sunrise time and in the sunset time. It is a figure which shows the example of the thumbnail of the imaged moving image.

  The thumbnail generation unit 105 divides sunrise to sunset into daytime and sunset to sunrise into night, and generates a thumbnail of moving images taken during the day and a thumbnail of moving images taken at night. The color of the thumbnails to be played is different. For example, if the imaged time is daytime, a map is generated in a bright color tone as shown in FIG. 26A, and if the imaged time is nighttime, the map is dark as shown in FIG. Generate by color tone.

  Then, when there is sunset or sunrise during the capturing of the moving image, the drive recorder 100 generates a thumbnail with both colors. FIG. 27A shows a thumbnail when sunset occurs during moving image capturing, and FIG. 27B shows a thumbnail when sunrise occurs. In FIG. 27, the horizontal direction of the thumbnail is the time axis, the left side is shown in early color tone, and the right side is shown in late color tone.

  As a result, the user can grasp when the image is captured with the color tone of the thumbnail, and convenience is improved.

  FIG. 28 is a diagram showing an example in which a thumbnail map is displayed in a north-up manner, FIG. 29 is a diagram showing an example in which the departure point is displayed on the left side, and FIG. 30 is a diagram showing an example in which the departure point is displayed on the right side. is there.

  For example, in the example of FIG. 28, the thumbnail generation unit 105 draws a route 71 on the map such that the direction of the map is north. The orientation of this map can be changed by the user's selection. For example, when displaying the departure point on the left side of the thumbnail is selected, the child imaging position of the departure point or the imaging start point among the child imaging positions However, the direction of the map is rotated so as to be on the left side with respect to the other child imaging positions to generate thumbnails (FIG. 29).

  In addition, when the thumbnail generation unit 105 selects to display the departure point on the right side of the thumbnail, the child imaging position of the departure point or the imaging start point is selected from the other child imaging positions among the child imaging positions. The thumbnail is generated by rotating the direction of the map so as to be on the right side (FIG. 30).

  Thereby, a user can grasp | ascertain a departure point easily.

  FIG. 31 is a diagram illustrating an example in which a display indicating a departure point and an arrival point is not displayed in the middle of a route. As shown in FIG. 14, the drive recorder 100 displays marks 96 at the departure point and arrival point of the route 69.

  On the other hand, when the end portion of the route 71 displayed on the thumbnail is neither the departure point nor the arrival point, that is, the middle portion, the mark 96 is not displayed as shown in FIG. For this reason, when there is no mark 96 at the end of the path shown in the thumbnail, it can be seen that this moving image and the following moving image exist separately.

32 and 33 are diagrams showing an example in which the order is displayed on the route on the thumbnail. The drive recorder 100 starts capturing moving images when the engine is started, and stops capturing moving images when the engine is stopped. During this time, since the drive recorder 100 records moving images at predetermined time intervals (for example, 20 minutes), a plurality of moving images are recorded when traveling for a predetermined time or longer. The route acquisition unit 104 counts the moving image from which the moving image starts, that is, the moving image from the departure point, and stores it in the parent DB 51 together with the travel data.

  When drawing a route on the thumbnail map, the thumbnail generation unit 105 reads the route order from the parent DB 51 and draws it at the position of each route. In FIG. 32, the first route 201 is drawn, a balloon 202 indicating the order is drawn on the route 201, and a balloon 203 indicating the order of the next route is drawn at a position on the next route. Has been.

  Also, in FIG. 33, the second route 204 is drawn, and a balloon 205 indicating the order is drawn on the route 204, and a balloon 202 indicating the order of the previous route at a position on the previous route. Is drawn, and a balloon 206 indicating the order of the next route is drawn at a position on the next route.

  FIG. 34 is a diagram showing an example in which the traveling direction is displayed on the route 204 on the thumbnail. The thumbnail generation unit 105 refers to the child DB 52, recognizes the traveling direction from the time difference of each child thumbnail data, and draws an arrow 207 indicating the direction on the map. For example, among the child thumbnail data, the child imaging position of the child thumbnail data at the latest time is the end point of the path 204, and thus the arrow 207 is drawn in such a direction that this position becomes the tip.

[Display method]
FIG. 35 is an explanatory diagram of processing for displaying thumbnails as a list. When the user instructs to display a list of moving images recorded in a specific storage area in the data storage 200 by operating the touch panel of the display device 400, a list display including information specifying the storage area is displayed. Is sent to the operation / display control unit 101 (step S310).

  Based on this list display instruction, the operation / display control unit 101 specifies a storage area to be displayed as a list, and acquires thumbnails stored in this area from the data storage 200 (step S320).

  In FIG. 22 and the like, an example in which thumbnails including external information are created has been described. However, when external information not included in thumbnails is added and displayed at the time of list display, the imaging position and time of each thumbnail are displayed on the external device 950. Is acquired, and external information that matches these information is acquired (step S330). When the external information is acquired, the external information is superimposed on the corresponding thumbnail. Note that step S330 may be omitted when external information is not added when the list is displayed.

  Then, a video signal in which a predetermined number of thumbnails are arranged in one screen is created and sent to the display device 400 for display (step S340).

  FIG. 36 is an explanatory diagram of processing for specifying a moving image corresponding to a thumbnail selected from the thumbnails displayed in a list, and FIG. 37 is a flowchart for reproducing a moving image corresponding to a thumbnail selected from the displayed thumbnails. FIG. 38 is a timing chart of processing for reproducing a moving image corresponding to a thumbnail selected from the thumbnails displayed in a list.

  The user looks at the thumbnails displayed in a list on the display device 400, searches for a thumbnail to be played back, and finds a thumbnail to be played back, and selects the found thumbnail. For example, the selection operation is performed by touching the area where the thumbnail is displayed.

The operation unit (for example, touch panel) 500 that has received this selection operation notifies the operation / display control unit 101 of the position selected by the user (step S410). The operation / display control unit 101 identifies the thumbnail displayed at the position selected by the user, and acquires the moving image name 210 of the moving image corresponding to the thumbnail with reference to the parent DB as shown in FIG. (Step S420).

  Then, the operation / display control unit 101 acquires a corresponding moving image from the data storage 200 based on the moving image name 210 acquired in step S420 (step S430), and displays a video signal based on this moving image on the display device 400. To be displayed (step S440).

  FIG. 39 is an explanatory diagram of a process of detecting a selection operation for a route on the thumbnail and starting playback of a moving image from a portion imaged at a position on the selected route. FIG. 40 is a diagram showing selected thumbnails. FIG. 41 is an explanatory diagram of processing for identifying a corresponding moving image. FIG. 41 is a diagram of processing for detecting a selection operation for a route on a thumbnail and starting playback of a moving image from a portion imaged at a position on the selected route. It is a timing chart.

  First, the user looks at the thumbnails displayed in a list on the display device 400, searches for a thumbnail to be reproduced, and selects and operates the thumbnail to be reproduced.

  The operation unit (for example, touch panel) 500 that has received this selection operation notifies the operation / display control unit 101 of the position selected by the user (step S510). The operation / display control unit 101 identifies the thumbnail displayed at the position selected by the user, and acquires the thumbnail from the data storage 200 (step S520). The operation / display control unit 101 creates a video signal so that the acquired thumbnail is displayed in a large size on the display screen of the display device 400, and sends the video signal to the display device 400 for display (step S530).

  The user views the thumbnail path displayed on the display device 400, and selects and operates a position on the path where playback is to be started.

  Upon receiving this selection operation, the operation unit 500 notifies the operation / display control unit 101 of the position selected by the user (step S540). The operation / display control unit 101 refers to the child DB 52 as shown in FIG. 40, identifies the child thumbnail data 302 having the screen x coordinate and the screen y coordinate 301 closest to the position selected by the user, and identifies the identified child The time 303 of the thumbnail data 302 is acquired (step S550). Further, the operation / display control unit 101 refers to the parent DB and acquires the moving image name of the moving image corresponding to the thumbnail selected in step S510 (step S560).

  Then, the operation / display control unit 101 acquires, from the data storage 200, data captured after the time acquired in step S550 among the moving images corresponding to the moving image name acquired in step S560 (step S570). A video signal based on the moving image data is sent to the display device 400 for display (step S580).

  Thereby, the playback of the moving image can be started from the portion corresponding to the position selected by the user on the route, not limited to the playback of the moving image from the top. For this reason, the part which a user wants to browse can be selected intuitively, and the convenience at the time of moving image reproduction improves.

[Modification]
39 to 41 described above show an example in which the thumbnail selected by the user is displayed in an enlarged manner to enable selection of a location on the route. However, the present invention is not limited to this, and the route portion of the thumbnail is selected. In such a case, the thumbnail may be enlarged. In this case, for example, the operation / display control unit 101 refers to the child DB 52 to obtain a route in the thumbnail from the child imaging position (latitude / longitude) of the thumbnail, and the position on the touch panel selected by the user is Whether or not the route is selected is determined based on whether or not the route is on the route. If it is determined that the route has been selected, the operation / display control unit 101 creates a video signal so that the thumbnail is displayed in a large size in the display screen of the display device 400, as in step S530 described above. , Sent to the display device 400 for display. And the above-mentioned step S540
As in the case of ˜580, when the user selects a location on the route of the thumbnail displayed in an enlarged manner, the moving image from the portion corresponding to the location selected by the user among the moving images corresponding to the thumbnail is displayed. Start playing.

  In addition, the selection on the route in the thumbnail displayed in an enlarged manner is not limited to simply selecting a single point, but is to select a range by tracing on the route or by selecting two points, the start point and the end point. There may be. In this case, a range corresponding to the range selected by the user is reproduced from the moving images corresponding to the thumbnail.

  In this modification, when the selection for the thumbnail before enlargement is not on the path, an operation other than the enlargement of the thumbnail is performed, such as playing a moving image corresponding to the thumbnail from the top.

  As described above, according to the present modification, by selecting the path displayed on the thumbnail, the user can specify the playback position of the moving image on the path, and intuitive operation is possible. become.
