JP 2009-49950 A

  However, in the imaging device 1 of Patent Document 1, there is a possibility that an image stored at every constant distance Lx does not represent an optimal moment for the user. Therefore, in order to store an image at the optimum moment, it is necessary to always store the image. In other words, in order to store an image at an optimal moment, the storage capacity increases.

  One object of the present invention is to provide a vehicle outdoor imaging device or the like that can suppress an increase in storage capacity. Other objects of the present invention will become apparent to those skilled in the art by reference to the following several and preferred embodiments and the accompanying drawings.

  In the following, in order to easily understand the outline of the present invention, embodiments according to the present invention will be exemplified.

A first aspect according to the present invention includes a detection unit that detects a predetermined change in a situation of a person inside a vehicle room;
An external imaging unit that continuously images the outside of the room to generate a series of external images;
When the predetermined situation change is detected by the detection unit, a storage unit that stores a part of the series of external images;
It is related with the imaging device outside a vehicle characterized by comprising.

  Since the series of external images are generated by the external imaging unit, the images at the optimum moment can be included. In other words, an image captured discontinuously (for example, at a certain distance) may not represent an optimal moment. The vehicular outdoor imaging device includes an external imaging unit, generates a series of external images including images at the optimal moment, and does not store all of the series of external images in the storage unit. A part is stored in the storage unit. Thereby, an increase in the storage capacity of the storage unit can be suppressed. In addition, the vehicle outdoor imaging device is configured to change a predetermined situation of a person inside the vehicle room (for example, when a person cheers, a person moves to the vehicle so that a part of a series of external images represents an optimal moment. It is equipped with a detection unit that detects that the outside of the room has been seen.

In the first aspect, the vehicle outdoor imaging device includes:
It may further comprise an internal imaging unit that continuously images the interior of the room to generate a series of internal images,
When the predetermined situation change is detected by the detection unit, the storage unit may also store a part of the series of internal images.

  The storage unit can store not only an external image (for example, scenery) at an optimal moment, but also an internal image (for example, a state inside a vehicle room) at an optimal moment.

  1st aspect WHEREIN: The said internal imaging part may be installed in the ceiling part of the said room so that a movement in the front direction and the back direction of the said room is possible.

  A more accurate internal image can be memorize | stored because an internal imaging part moves to the front direction and back direction (front-back direction) of the compartment of a vehicle. In particular, when the vehicle room is long in the front-rear direction, such as a one-box car or a bus, such an internal imaging unit is more effective.

In the first aspect, the detection unit may be a detection imaging unit that generates an image for detection by imaging from the front to the rear of the room,
The detection imaging unit may detect the predetermined state change by detecting a predetermined pixel change in a region where a driver and a window are removed from the detection image.

  In general, a driver's movement occurs with driving, and a scenery or the like through a window changes with the movement of the vehicle. Therefore, even if a predetermined situation change is detected by the detection image pickup unit by excluding such a region having a relatively large pixel change from the detection image, the driver or other user intends to It can suppress that the image which is not memorize | stored in a memory | storage part.

In the first aspect, the detection unit may be a detection recording unit that records the inside of the chamber and generates a detection sound.
The detection recording unit may detect the predetermined change in the situation by detecting a predetermined volume change when the detection sound is equal to or higher than a predetermined value.

  In general, traveling sound is transmitted to the interior of the vehicle compartment as the vehicle moves. Therefore, even when a predetermined change in the situation is detected by the recording unit for detection by excluding such a sound that does not represent an essential internal sound from the detection sound, the driver or the like It is possible to prevent an image unintended by the user from being stored in the storage unit.

  Those skilled in the art will readily understand that the illustrated embodiments according to the present invention can be further modified without departing from the spirit of the present invention.

  The preferred embodiments described below are used to facilitate an understanding of the present invention. Accordingly, those skilled in the art should note that the present invention is not unduly limited by the embodiments described below.

  FIG. 1 is a schematic configuration diagram of a vehicle outdoor imaging device according to the present invention. As shown in FIG. 1, the vehicle outdoor imaging device includes a detection unit such as a detection microphone 10, an external imaging unit such as a vehicle camera 40, and a storage unit such as a storage unit 60. The detection unit detects a predetermined change in the situation of a person inside the vehicle room 130 such as an automobile (a user of the vehicle outdoor imaging device), and can be configured by the detection microphone 10 and / or the detection camera 20, for example. . The external imaging unit continuously captures the outside of the room 130 and generates a series of external images. A series of external images are stored in the primary storage unit 50, for example. When a predetermined change in the situation of a person inside the room 130 is detected by the detection unit, the storage unit 60 stores a part of the series of external images. Note that the primary storage unit 50 may be configured by, for example, an internal memory of the vehicle camera 40, a flash memory drive, or the like, and the storage unit 60 may be configured by, for example, a hard disk drive or the like.

  Since the vehicle camera 40 continuously captures the outside of the room 130, for example, as shown in FIG. 3B of Patent Document 1, it differs from the imaging device 1 that captures an image at every constant distance Lx. . In other words, since the vehicle camera 40 continuously captures the outside of the room 130 and generates a series of external images, the series of external images can include images at the optimal moment. On the other hand, an image captured discontinuously (for example, every fixed distance) may not represent an optimal moment.

  Note that if a series of external images is always stored, the storage capacity increases. Therefore, the primary storage unit 50 stores only a certain amount of the latest series of external images, and the old external images are sequentially replaced with new external images. In other words, the series of external images is only temporarily stored in the primary storage unit 50, and the primary storage unit 50 can store a certain amount of series of external images endlessly.

  Furthermore, the storage unit 60 can store a part of a series of external images at a certain timing. In other words, the storage means 60 does not always store a series of external images, but stores a part of the series of external images at a timing that includes an image at an optimal moment. Thereby, an increase in the storage capacity of the storage means 60 can be suppressed. In addition, the detection microphone 10 detects, for example, that a person raised a cheer so that a part of a series of external images represents an optimal moment, and the detection camera 20 detects, for example, that the person is in the room 130. Detects looking outside.

  In the example of FIG. 1, the vehicle outdoor imaging device can further include an internal imaging unit such as an in-vehicle camera 70. The internal imaging unit continuously images the inside of the chamber 130 to generate a series of internal images. The primary storage means 60 can store both a series of external images and a series of internal images endlessly with a predetermined storage capacity. When a predetermined change in the situation of a person inside the room 130 is detected by, for example, the detection microphone 10, the storage unit 60 stores both a part of the series of external images and a part of the series of internal images. Remember. The storage unit 60 can store not only an external image (for example, scenery) at an optimal moment, but also an internal image (for example, a state inside a vehicle room) at an optimal moment.

  In the example of FIG. 1, the vehicle outdoor imaging device includes both the detection microphone 10 and the detection camera 20, and further includes a state change determination unit 30. For example, the detection unit can be configured by the detection microphone 10, the detection camera 20, and the situation change determination unit 30. A detection recording unit such as the detection microphone 10 records the inside of the room 130 to generate a detection sound, and sends the generated detection sound to a processing unit such as the situation change determination unit 30. A detection imaging unit such as the detection camera 20 images the inside of the room 130 to generate a detection image, and sends the generated detection image to a processing unit such as the situation change determination unit 30. The processing unit such as the situation change determination unit 30 can be configured by, for example, a CPU, MPU, ECU, or the like. The situation change determination means 30 determines whether or not there is a predetermined situation change of a person based on the detection sound and / or the detection image. When there is a predetermined change in the situation of the person, the situation change determination means 30 can send a signal (trigger signal) indicating that the predetermined change in the situation of the person has occurred to the primary storage means 50. Based on this signal, the primary storage means 50 can send both a part of the series of external images and a part of the series of internal images to the storage means 60.

  In the example of FIG. 1, the vehicle outdoor imaging device can further include a manual button 90. The manual button 90 can detect a person's operation, and when the person presses the manual button 90, the manual button 90, for example, sends a trigger signal (a signal representing what the person wants to memorize) to the situation change determination means 30. ) Can be sent. When a person presses the manual button 90, the storage unit 60 can store, for example, a part of a series of external images based on a trigger signal from the situation change determination unit 30, for example. Since the detection unit such as the detection microphone 10 automatically detects a predetermined change in the situation of the person, there is an advantage that the load on the person is small, and the manual button 90 is more reliably used at the optimum moment. It is an advantage to store the images.

  In the example of FIG. 1, the vehicle outdoor imaging device can further include a manual switch 100. The manual switch 100 can control the situation change determination means 30 so that the trigger signal is not sent from the situation change determination means 30 to the primary storage means 50. For example, it is possible to prevent the storage unit 60 from storing images that are not intended by a person, such as a door opening / closing sound of a vehicle and a start sound of a vehicle engine. In the example of FIG. 1, the vehicle outdoor imaging device can further include a display device 110, an operation button 120, and an operation means / drive means 80, which will be described later.

  FIG. 2 shows an arrangement example of the vehicle outdoor imaging device. In the example of FIG. 2, the vehicle exterior camera 40 (external imaging unit) in FIG. 1 includes, for example, three vehicle exterior cameras 40a, 40b, and 40c. Of course, the external imaging unit may be configured with one vehicle-mounted camera or a plurality of vehicle-mounted cameras. In the example of FIG. 2, the exterior camera 40a is disposed, for example, behind a roof of the automobile, the exterior camera 40b is disposed, for example, on a dashboard, and the exterior camera 40c is disposed on a front bumper of the automobile. . Each of the three external cameras 40a, 40b, and 40c can continuously capture the outside of the room 130 and generate a series of external images.

  In the example of FIG. 2, the detection microphone 10 (detection unit) in FIG. 1 includes, for example, two detection microphones 10 a and 10 b. In the example of FIG. 2, the detection microphone 10a is disposed, for example, in front of the ceiling, and the detection microphone 10b is disposed, for example, in the rear of the ceiling. Each of the detection microphones 10a and 10b can continuously record the inside of the chamber 130 to generate a series of detection sounds. In the example of FIG. 2, for example, the detection camera 20 and the in-vehicle camera 70 are arranged on the ceiling. The detection camera 20 (detection unit) can continuously capture the inside of the chamber 130 and generate a series of detection images. The in-vehicle camera 70 (internal imaging unit) can continuously image the inside of the room 130 and generate a series of internal images.

  In the example of FIG. 2, the situation change determination unit 30 of FIG. 1 is disposed, for example, behind the floor, the manual switch 100 of FIG. 1 is disposed, for example, in the first sheet row, and the display device 110 of FIG. For example, it is arranged inside the dashboard. Although the manual button 90 and the operating means / driving means 80 in FIG. 1 are not shown, they can be arranged near the manual switch 100, for example. Also, the operation button 120 of FIG. 1 is not shown, but this is because, for example, the display device 110 is configured by a touch panel type display, and the touch panel type display serves as both the display device 110 and the operation button 120. Also good.

  3A, FIG. 3B, FIG. 3C, and FIG. 3D respectively show the detection microphone 10b, the detection camera 20, the vehicle exterior camera 40a, and the vehicle interior camera 70 of FIG. An appearance example is shown. The detection microphone 10b corresponds to, for example, the second and third sheet rows other than the first sheet row, and can detect a human voice behind the chamber 130 (FIGS. 2 and 3A). ). Further, when the detection microphone 10b is arranged on the right side behind the ceiling, for example, a detection microphone (not shown) may be further added, and the added detection microphone may be arranged on the left side behind the ceiling, for example. In other words, the detection microphone 10b disposed behind the ceiling may be constituted by two microphones.

  The detection camera 20 can detect, for example, the movement of a person inside the room 130 by, for example, capturing images from the front to the rear of the room 130 (FIGS. 2 and 3B). For example, the outside camera 40a can capture a scene outside the room 130, and can be configured by, for example, a 360-degree camera (omnidirectional camera) (FIGS. 2 and 3C). The in-vehicle camera 70 is installed, for example, on the ceiling 130 of the room 130 so as to be movable in the front direction DR1 and the rear direction DR2 of the room 130 (FIGS. 2 and 3D). In the example of FIG. 3D, the in-vehicle camera 70 can be moved along the rail 71 by, for example, a motor (not shown).

  By moving the in-vehicle camera 70 (internal imaging unit) in the front-rear direction of the chamber 130, a more accurate internal image can be stored in the storage unit 60. In particular, when the vehicle room 130 is long in the front-rear direction, such as a one-box car or a bus, such an in-vehicle camera 70 is more effective. As shown in FIG. 2, the detection microphone 10 includes, for example, two detection microphones 10 a and 10 b, and whether the cheer is raised in front of the chamber 130 or whether the cheer is raised in the rear of the chamber 130. Can be detected. The in-vehicle camera 70 can move in the front-rear direction of the room 130 so as to automatically approach the place where the cheers are raised.

  FIG. 4A shows an example of a temporal change in sound pressure generated by the detection microphone 10 of FIG. The sound pressure can be obtained, for example, by summing the sound pressures from the two detection microphones 10a and 10b. However, when detecting a place where a cheer is raised, the sound pressure shown in FIG. The sound pressure from the detection microphone is preferably. In the example of FIG. 4A, the sound pressure (solid line) increases by a predetermined amount at time T, and the sound pressure (bar graph) represents the sound for detection sampled at a predetermined interval. A predetermined volume change at time T as shown in FIG. 4A (change in which the difference between the previously sampled sound pressure and the current sampled sound pressure increases by a predetermined amount) is, for example, a situation It can be detected by the change determination means 30 (processing unit).

  By the way, in general, traveling sound is transmitted to the inside of the chamber 130 with the movement of the automobile. Therefore, it is preferable to exclude such a sound that does not represent an essential internal sound from the sound for detection. Therefore, the situation change determination means 30 (processing unit, detection recording unit) determines whether or not the detection sound has a predetermined volume change only when the detection sound is equal to or higher than a predetermined value. It is preferable to do. In other words, for example, a sound pressure smaller than a predetermined value represented by a dotted line in FIG. 4A can be regarded as road noise. By detecting a predetermined volume change when the state change determination unit 30 has a detection sound equal to or higher than a predetermined value, it is possible to suppress the storage unit 60 from storing an image that is not intended by a person. The situation change determination means 30 may filter the sound for detection, and the sound pressure shown in FIG. 4A is obtained by a person (preferably a person who has been recognized in advance) through a filter by frequency. ) May be detected.

  FIG. 4B shows an example of the vehicle speed dependence of the predetermined value in FIG. As shown in FIG. 4B, the predetermined value can be changed according to the vehicle speed. In general, the running noise (road noise) increases according to the vehicle speed. However, even when the vehicle speed is high, the running noise is saturated, and even if the vehicle speed is slow or the car stops, the outside of the chamber 130 May be transmitted to the inside of the chamber 130. In the example of FIG. 4B, the predetermined value increases linearly between the vehicle speed V1 and the vehicle speed V2, but the setting of the predetermined value is not limited to the example of FIG. 4B.

  FIG. 5 shows an example of an image generated by the detection camera 20 of FIG. In the example of FIG. 5, the number of people inside the room 130 is four, and the image generated by the detection camera 20 is an adult male driver (driver seat in the first seat row), an adult Includes female (passenger seat in first seat row), male child (second seat row) and female child (second seat row). In the example of FIG. 5, the image generated by the detection camera 20 also includes windows 132, 133, 134, and 135. In general, a driver's movement is caused by driving, and a scenery or the like through the windows 132, 133, 134, 135, and 136 is changed as the automobile moves. Therefore, it is preferable to exclude such a region having a relatively large pixel change from the detection image. Therefore, it is preferable that the detection camera 20 detects a predetermined pixel change in a region where the driver and the window are removed from the detection image. As shown in FIG. 5, the center line 0B of the room 130 passes through the midpoint between the driver's seat and the passenger seat, and the vicinity of the center line 0B (except for the area of the rear window 136 (rear window)) This is a region where the pixel change is relatively small. In the example of FIG. 5, detection areas 21 and 22 are set in the vicinity of the center line 0B. The detection area 21 is, for example, an area behind the ceiling portion 131 (above the rear window 136), and the detection area 22 is, for example, This is the area between the driver's seat and the passenger seat (below the rear window 136). The detection area 21 can detect, for example, that the male and female children in the second sheet row step up, and the detection area 22 can detect, for example, that an adult male and female in the first sheet row hold hands. . It is preferable that the detection camera 20 detects a predetermined pixel change in an area set in the vicinity of the center line 0B such as the detection area 21 (excluding the area of the rear window 136).

  FIG. 6 shows a configuration example of a moving image stored in the storage unit 60 of FIG. In the example of FIG. 6, the time T corresponds to the time T in FIG. 4A, for example, and represents the time when a predetermined change in the situation of the person is detected. As shown in FIG. 6, the primary storage unit 50 of FIG. 1 can record a series of external images, and the storage unit 60 of FIG. 1 stores, for example, 15 times T from the time 5 seconds before the time T. Only a part of a series of external images corresponding to the time after second can be saved. In the example of FIG. 6, the image stored in the storage unit 60 is a moving image for 20 seconds, for example, but the time for storing the moving image is not limited to 20 seconds. Further, the storage unit 60 may store a moving image for, for example, 20 seconds after the time T, or may store a still image triggered by the time T.

  7A shows an example of the appearance of the display device 110 in FIG. 1, and FIG. 7B shows a display example of the icon 111 in the display area of the display device 110. FIG. In the example of FIG. 7A, the display device 110 is a car navigation device. The car navigation device (display device 110) can display a map and an icon 111 representing the operating status of the vehicle outdoor imaging device. As shown in FIG. 7B, for example, the icon 111 can distinguish and display “recording”, “recording complete, playback possible”, and “played”. The icon 111 representing “recording” can be represented in red, for example, the icon 111 representing “recording complete, playback possible” can be represented in yellow, for example, and the icon 111 representing “played” can be represented, for example, Can be represented in green.

  For example, when a moving image for 20 seconds is being recorded in the storage unit 60, an icon 111 indicating "recording" is displayed. When the recording of the moving image in the storage means 60 is completed, an icon 111 indicating “recording complete, playback possible” is displayed before the moving image is played back. When the reproduction of the moving image in the storage unit 60 is completed, an icon 111 indicating “reproduced” is displayed before the next moving image is recorded in the storage unit 60. The operation button 120 in FIG. 1 can control the display device 110, and can be configured by an icon 111 representing “recording completion, reproduction possible”, for example. That is, when the icon 111 indicating “recording complete, playback is possible” is displayed, when the person touches the icon 111, the car navigation device switches from the navigation screen including the map to the playback screen, and the car navigation device (display The apparatus 110) can display the moving image in the storage means 60 (see, for example, FIG. 8A).

  As shown in FIG. 7B, the icon 111 can also display, for example, “voice trigger” and “movement trigger” separately. The icon 111 representing “voice trigger” can be represented by an illustration representing a mouth, for example, and means that the time T (trigger) in FIG. The icon 111 representing “movement trigger” can be represented by an illustration representing a hand, for example, which means that the time T (trigger) in FIG.

  After the predetermined situation change of the person is detected at time T (trigger), while the icons 111 representing “recording” and “recording complete, playback possible” are displayed, the situation change determination means 30 The determination process may be stopped. Thereby, the transmission of a new trigger is prevented from the situation change determination unit 30, and the storage unit 60 can prevent a useless reaction. Furthermore, after the icon 111 indicating “reproduced” is displayed, the situation change determination unit 30 may stop the determination process, for example, for 5 seconds. Immediately after the moving image stored in the storage unit 60 is reproduced, there is a possibility that a human voice (such as an impression of the moving image) may be generated, and the storage unit 60 can prevent a useless reaction.

  FIG. 8 shows a reproduction example of a moving image recorded in the storage unit 60 of FIG. In the example of FIG. 8A, images displayed on the car navigation device (display device 110) are internal images 71 and 72 captured by the in-vehicle camera 70 (internal image capturing unit), and for example, an in-vehicle camera 40a ( And external images 41 and 42 imaged by an external imaging unit). The in-vehicle camera 70 can be configured by a 360 degree camera, the internal image 71 corresponds to an image for 0 to 180 degrees, for example, and the internal image 72 corresponds to an image for 180 to 360 degrees, for example. Further, the display device 110 can display an icon representing the loop button 112. In the example of FIG. 8B, images displayed on the display device 110 include internal images 71 and 72 (small screen) and external images 41 and 42 (large screen).

  The operation button 120 in FIG. 1 can be configured by, for example, the external images 41 and 42 (small screen) and the loop button 112 in FIG. That is, in the example of FIG. 8A, when a person touches the external images 41 and 42 (small screen), the display device 110 enlarges the external images 41 and 42 and reduces the internal images 71 and 72. (See, for example, FIG. 8B). Further, in the example of FIG. 8A, when a person touches the loop button 112, the display device 110 can continuously reproduce the moving images recorded in the storage unit 60.

  FIG. 9 shows an example of reproduction of a moving image (internal images 71 and 72) recorded in the storage means 60 of FIG. FIG. 9A shows an example of the internal images 71 and 72 when the in-vehicle camera 70 of FIG. 2 is arranged at a position that places importance on the first sheet row, for example. FIG. 9B shows an example of the internal images 71 and 72 when the in-vehicle camera 70 of FIG. 2 is arranged at a position that places importance on the second sheet row, for example. FIG. 9C shows an example of the internal images 71 and 72 when the in-vehicle camera 70 of FIG. 2 is arranged at a position that places importance on the third sheet row, for example. As described above, the in-vehicle camera 70 can automatically move in the front-rear direction in accordance with the detection of the human voice by the detection microphone 10, but the predetermined location determined for each seat row By moving to, the facial expression of the person inside the room 130 can be stored more accurately. In addition, the operating means / driving means 80 in FIG. 1 can also move the position of the in-vehicle camera 70 back and forth by a person. When the person operates the operating means 80, the driving means 80 responds to the operation.
