[Configuration of drive recorder device]
FIG.1 and FIG.2 shows the structure of the drive recorder 1 based on an Example. Specifically, FIG. 1 shows a front view of a state in which the drive recorder 1 is mounted on a room mirror 12 in a vehicle interior (also simply referred to as “mounted state”). 2A shows a rear view of the drive recorder 1 in the mounted state, and FIG. 2B shows a top view of the drive recorder 1 in the mounted state. Hereinafter, the longitudinal direction of the drive recorder 1 is “Y-axis direction”, the short direction of the drive recorder 1 is “X-axis direction”, and the direction perpendicular to the Y-axis and the X-axis is “Z-axis direction”. Is determined as shown in the figure.

  The drive recorder 1 is driven by a built-in secondary battery, and is mainly sandwiched between a mirror unit 13, a front shooting camera 4F, a rear shooting camera 4R, and a display (display means) 10 existing on the back of the mirror unit 13. Part 14A-14D. In the mounted state, the drive recorder 1 is fixed to the rearview mirror 12 by the sandwiching portions 14A to 14D sandwiching the rearview mirror 12. When the drive recorder 1 is mounted, the mirror surface of the room mirror 12 and the back surface of the drive recorder 1 overlap. The drive recorder 1 is an example of the “photographing device” in the present invention.

  The front shooting camera 4F is a camera for generating an image of the front of the vehicle (also referred to as “front image Imf”). The drive recorder 1 is not overlapped with the rearview mirror 12 when the drive recorder 1 is mounted. Located on the back part. The front photographing camera 4F is a wide-angle camera having a wider angle of view “θf” in the horizontal direction than a rear photographing camera 4R described later. The shooting direction of the front shooting camera 4F (see arrow 8F) is fixed in a state of being directed in a direction substantially perpendicular to the room mirror 12 (that is, the Z-axis direction). The front photographing camera 4F is an example of the “first photographing unit” in the present invention, and the front image Imf is an example of the “first image” in the present invention.

  The rear camera 4R is a camera for generating an image (also referred to as “vehicle interior image Imr”) in which the vehicle interior including the driver's position is captured, and has a general camera angle of view “θr”. . In FIG. 1 and FIG. 2, the rear camera 4R is provided at the center in the longitudinal direction of the drive recorder 1 and at the lower end position in the short direction. The photographing direction of the rear photographing camera 4R (see arrow 8R) is fixed in a state of being directed in a direction substantially perpendicular to the room mirror 12 (that is, the Z-axis direction). The photographing direction of the rear photographing camera 4R (that is, the positive Z-axis direction) is opposite to the photographing direction of the front photographing camera 4F (that is, the negative Z-axis direction). The rear photographing camera 4R is an example of the “second photographing unit” in the present invention, and the vehicle interior image Imr is an example of the “second image” in the present invention.

  The mirror unit 13 is, for example, a half mirror, and transmits a part of incident light and reflects other light. Thereby, the mirror unit 13 functions as a normal mirror that reflects the rear landscape of the vehicle when the display 10 on the back surface is not emitting light, and allows the light emitted from the display 10 to pass through when the display 10 is in emitting light. The driver is caused to visually recognize the display content on the display 10.

  The display 10 displays an image cut out from the front image Imf (also referred to as “cut-out image Imc”). As will be described later, the cut-out image Imc is an image cut out from the front image Imf so that the front landscape in the front direction of the vehicle becomes the center of the image, and has fewer vertical and horizontal pixels than the front image Imf. In addition, the display 10 superimposes and displays an image (also referred to as “guidance image”) representing characters, figures, and the like for guiding the driver on the cutout image Imc. In FIG. 1, the display 10 displays a guide image representing the vehicle speed and a square frame guide image highlighting a lit signal light superimposed on the cut-out image Imc.

  FIG. 3 is a functional block diagram of the drive recorder 1. As shown in FIG. 3, the drive recorder 1 includes a front shooting camera 4F, a rear shooting camera 4R, an acceleration sensor 6, a display 10, a RAM 11, a nonvolatile memory 15, and a control unit 19.

  The RAM 11 is a storage area that functions as an image buffer or the like that temporarily stores the cutout image Imc cut out from the front image Imf by the control unit 19. The non-volatile memory 15 is a storage medium such as an SD card, for example, and when an impact due to an accident or the like occurs, an image for a predetermined time before the occurrence of the impact stored in the RAM 11 is written by the control unit 19. .

  The control unit 19 is a CPU or the like, generates a cutout image Imc by cutting out a part from the front image Imf, displays the cutout image Imc on the display 10, and writes the cutout image Imc in the RAM 11 for a predetermined time. The cut-out image Imc of the minute is stored in the RAM 11. Further, when the acceleration sensor 6 detects an acceleration (that is, an impact) equal to or higher than the reference value by the acceleration sensor 6, the control unit 19 displays the cut-out image Imc for a predetermined time (approximately 10 to 100 seconds) stored in the RAM 11. Write to. Further, in the present embodiment, the control unit 19 determines a position (also simply referred to as “cutout position”) for cutting out the cutout image Imc from the front image Imf based on the position of the driver's face in the vehicle interior image Imr. To do. The control unit 19 is an example of an “image control unit” and a “computer” that executes a program in the present invention.

[How to determine the clipping position]
Next, a method for determining the cutout position in the front image Imf will be described. Schematically, the control unit 19 uses the center of the vehicle interior image Imr as a reference point, and shifts the cutout position in the front image Imf in the reverse direction according to the distance that the driver's face is horizontally separated from the reference point. .

(1) Outline Description FIG. 4 is an overhead view of a passenger compartment in which the drive recorder 1 is installed. In FIG. 4, lines “L1” and “L2” indicate light incident on the driver's eyes when the driver observes the rear of the vehicle (that is, the direction opposite to the traveling direction of the vehicle) via the drive recorder 1. The optical axis is shown. The line “L3” indicates a line extending in the traveling direction of the vehicle with the front photographing camera 4F as a starting point.

  In the example of FIG. 4, the driver adjusts the angle in the horizontal direction of the drive recorder 1 (that is, the room mirror 12) so that the rear of the vehicle can be confirmed by the mirror unit 13. Thereby, the photographing direction of the rear photographing camera 4R indicated by the arrow 8R is inclined to the right by an angle “θin” with respect to the line L2 extending rearward of the vehicle. Here, the angle θin is equal to the angle formed by the line L1 connecting the drive recorder 1 and the driver's face and the arrow 8R indicating the photographing direction of the rear photographing camera 4R.

  On the other hand, in this case, the photographing direction of the front photographing camera 4F indicated by the arrow 8F is deviated by an angle “θout” leftward with respect to the traveling direction of the vehicle in which the line L3 extends. Here, the angle θin and the angle θout are in a complex angle relationship, and since the line L2 and the line L3 are parallel, the angle θin and the angle θout are equal. Therefore, the angle difference in the horizontal direction of the driver's face with respect to the shooting direction of the rear shooting camera 4R is equal to the angle difference in the horizontal direction of the traveling direction of the vehicle with respect to the shooting direction of the front shooting camera 4F.

  FIG. 5A shows a vehicle interior image Imr captured by the rear camera 4R in the example of FIG. Here, lines 70v and 70h indicate vertical and horizontal center lines of the vehicle interior image Imr.

  In the vehicle interior image Imr shown in FIG. 5A, the position of the driver's face (specifically, the position of the driver's eyes) is a predetermined number of pixels (“pixel number Nin”) relative to the center of the vehicle interior image Imr. It is just shifted to the left. Here, the number of pixels Nin increases as the angle θin in FIG. 4 increases, and the relationship between the number of pixels Nin and the angle θin is determined according to the specifications of the rear photographing camera 4R. Therefore, the control unit 19 calculates the number of pixels Nin by detecting the position of the driver's face from the vehicle interior image Imr using a known face recognition technique, and then refers to information indicating the relationship between the number of pixels Nin and the angle θin. Thus, the angle θin (that is, the angle θout) can be calculated from the number of pixels Nin. Information indicating the relationship between the number of pixels Nin and the angle θin is calculated in advance, for example, by experiment or theoretical calculation and stored in the control unit 19.

  FIG. 5B shows a front image Imf taken by the front camera 4F in the example of FIG. In FIG. 5B, lines 71v and 71h indicate the vertical and horizontal center lines of the forward image Imf, and the line 72v indicates the vertical center line of the cut-out image Imc.

  In the example of FIG. 5B, the vanishing point that is substantially in the traveling direction of the vehicle is shifted to the right by a predetermined number of pixels (also referred to as “number of pixels Nout”) with respect to the center of the forward image Imf. Here, the number of pixels Nout increases as the angle θout in FIG. 4 increases, and the relationship between the number of pixels Nout and the angle θout is determined according to the specifications of the front photographing camera 4F. Therefore, the control unit 19 stores in advance the relationship between the number of pixels Nout and the angle θout calculated by experiment or theoretical calculation, and calculates the number of pixels Nout from the angle θout. Then, the control unit 19 determines the cutout position in the front image Imf so that the position shifted to the right by the number of pixels Nout from the center of the front image Imf becomes the center of the cutout image Imc.

  FIG. 6A shows the vehicle interior image Imr when the angle θin (that is, the angle θout) is smaller than the example of FIG. FIG. 6B shows the front image Imf in the example of FIG.

  Since the pixel number Nin has a positive correlation with the angle θin, the pixel number Nin is smaller in the example of FIG. 6A than in the example of FIG. Since the pixel number Nout has a positive correlation with the angle θout (= θin), the pixel number Nout is smaller in the example of FIG. 6B than in the example of FIG.

  FIG. 7A shows a vehicle interior image Imr photographed when the driver's seat is on the left side of the vehicle interior, and FIG. 7B shows a front image Imf in the example of FIG. 7A.

  In the example of FIG. 7, the vehicle on which the drive recorder 1 is mounted is a left-hand drive vehicle, and the shooting direction of the front shooting camera 4F in this case is shifted to the right with respect to the traveling direction of the vehicle. Therefore, in the vehicle interior image Imr shown in FIG. 7A, the position of the driver's face is opposite to the examples in FIGS. 5A and 6A with respect to the vertical center line 70v of the vehicle interior image Imr. Is shifted to the right. Similarly, in the front image Imf shown in FIG. 7B, the position in the front direction of the vehicle with respect to the vertical center line 71v of the front image Imf is opposite to the examples in FIGS. 5B and 6B. It is shifted to the left. Accordingly, when the control unit 19 determines that the position of the driver's face is present to the right of the vertical center line 70v in the vehicle interior image Imr, the control unit 19 shifts to the left with respect to the center of the front image Imf by the number of pixels Nout. Is determined at the center of the cut-out image Imc.

(2) Processing Flow FIG. 8 is a flowchart showing the procedure for determining the cutout position in the front image Imf. The control unit 19 repeatedly executes the process of the flowchart shown in FIG.

  First, the control unit 19 detects the driver's face from the vehicle interior image Imr using a known image recognition technique (step S101). In this case, the control unit 19 detects, for example, the center of both eyes of the driver as the position of the driver's face.

  Next, the control unit 19 calculates the number Nin of pixels in which the driver's face is horizontally separated from the reference point with the center of the vehicle interior image Imr as the reference point (step S102). And the control part 19 calculates angle (theta) out (namely, angle (theta) in) from which the imaging | photography direction of the front imaging | photography camera 4F has shifted | deviated from the advancing direction of a vehicle in a horizontal direction from the calculated pixel count Nin (step S103).

  Next, the control unit 19 sets a position shifted in the horizontal direction from the center of the forward image Imf by the number of pixels Nout corresponding to the angle θout calculated in step S103, as the center of the cut-out image Imc (step S104). In this case, the control unit 19 shifts the center of the cut-out image Imc from the center of the front image Imf by the number of pixels Nout in the direction opposite to the direction in which the position of the driver's face is shifted from the center of the vehicle interior image Imr. Thereby, the control part 19 can acquire suitably the cut-out image Imc which reflected the front direction of the vehicle.

  As described above, the drive recorder 1 according to the present embodiment includes the front photographing camera 4F that photographs the front scenery of the vehicle, the rear photographing camera 4R that photographs the driver of the vehicle, and the control unit 19. The control unit 19 cuts out a partial range of the front image Imf captured by the front shooting camera 4F as a cutout image Imc. At this time, the control unit 19 changes the position at which the cutout image Imc is cut out from the front image Imf according to the position of the driver in the vehicle interior image Imr taken by the rear camera 4R. By doing in this way, even if the angle of the rearview mirror 12 is changed, the drive recorder 1 does not adjust the shooting direction of the front shooting camera 4F, and the clipped image Imc shot in an appropriate direction. It can be displayed on the display 10 or stored in the nonvolatile memory 15.

[Modification]
Hereinafter, modified examples suitable for the above-described embodiments will be described. The following modifications may be applied in any combination to the above-described embodiments.

(Modification 1)
In the embodiment, a case has been described in which the shooting direction of the front shooting camera 4F is deviated from the traveling direction of the vehicle in the horizontal direction. Instead of this, or in addition to this, the control unit 19 in the front image Imf in the vertical direction of the cut-out image Imc when the shooting direction of the front shooting camera 4F is shifted in the vertical direction from the traveling direction of the vehicle. May be adjusted.

  In this case, the control unit 19 calculates the number of pixels corresponding to the distance in the vertical direction between the center of the vehicle interior image Imr and the position of the driver's face in step S102 of FIG. Thereafter, in step S103, the control unit 19 calculates an angle at which the shooting direction of the front shooting camera 4F is deviated from the traveling direction of the vehicle in the vertical direction based on the calculated number of pixels, as in the embodiment. Then, in step S104, the control unit 19 sets a position shifted in the vertical direction from the center of the front image Imf by the number of pixels corresponding to the angle calculated in step S103, as the center of the cut-out image Imc. In this case, as in the embodiment, the control unit 19 shifts the center of the cut image Imc from the center of the front image Imf in the direction opposite to the direction in which the position of the driver's face is shifted from the center of the vehicle interior image Imr.

  As a result, the drive recorder 1 is preferably configured so that the center of the cut-out image Imc is the center of the vehicle even when the driver adjusts the angle around the Y axis of the drive recorder 1 (ie, the room mirror 12) according to the seating height or the like. The cutout position can be determined so as to overlap the position in the traveling direction.

(Modification 2)
The control unit 19 may calculate the number of pixels Nin in step S102 by detecting the average position of the face in a predetermined period based on the statistical method in step S101 of FIG. Accordingly, when the driver temporarily moves the face without changing the angle of the rearview mirror 12, it is preferable to appropriately suppress the position of the cut-out image Imc in the front image Imf from being sensitively moved. it can.

(Modification 3)
In the above embodiment, the drive recorder 1 includes the clamping portions 14A to 14D for sandwiching and holding the drive recorder 1 in the genuine room mirror 12 attached to the vehicle. Instead of this, the drive recorder 1 may not be provided with the clamping portions 14A to 14D, but may be replaced with a genuine room mirror that is built in the rearview mirror and attached to the vehicle.

  In another example, the drive recorder 1 may be a navigation device that does not have a function of storing the clipped image Imc at the time of the accident in the nonvolatile memory 15. In this case, the navigation device detects the lane, the lighting state of the traffic light, the preceding vehicle, and the like by the image recognition process for the cutout image Imc, and superimposes the text image, the graphic image, and the like based on the detection result on the cutout image Imc. The information is displayed on the display 10 or voice information is output.

(Modification 4)
Instead of step S103 and step S104 in FIG. 8, after calculating the pixel number Nin in step S102, the control unit 19 may directly calculate the pixel number Nout from the pixel number Nin without calculating the angle θout.

  Here, since the angle θin and the number of pixels Nin, and the angle θout and the number of pixels Nout have a positive correlation, the pixel number Nout and the number of pixels Nin also have a positive correlation. Therefore, the control unit 19 can suitably calculate the number of pixels Nout from the number of pixels Nin by previously obtaining and storing an equation indicating the relationship between the number of pixels Nin and the pixel Nout through experiments or theoretical calculations. it can.
