FIG. 4 is a front view showing the imaging device with the lower housing removed, FIG. 5 is a bottom view showing the imaging device with the lower housing removed, and FIG. FIG. 3 is a rear view showing the imaging device in a detached state.

The imaging device 1 of the present embodiment is, for example, a stereo camera arranged in the interior of a car, captures an image of the front of the vehicle via a left imaging unit 10L and a right imaging unit 10R, and calculates parallax from the captured image. A distance image is generated by calculation, and an object ahead of the vehicle is recognized based on the generated distance image. The imaging apparatus 1 mainly includes a left imaging unit 10L and a right imaging unit 10R that are arranged at predetermined intervals, a control board 20 that is arranged between the left imaging unit 10L and the right imaging unit 10R, The housing 30 includes the imaging unit 10L, the right imaging unit 10R, and the control board 20.

The left imaging unit 10L includes an imaging device 11 and a left imaging substrate (first imaging substrate) 12L on which the imaging device 11 is mounted. As shown in FIG. 2, the left imaging board 12L is electrically connected to the control board 20 via a left wiring section (first wiring section) 14L. The left imaging substrate 12L is fixed to the front side of the housing 30 so as to be orthogonal to the imaging direction of the left imaging unit 10L (that is, the front of the vehicle). The image sensor 11 is mounted on the front surface of the left imaging substrate 12L facing the front of the vehicle. The image sensor 11 is, for example, a CMOS image sensor.

The left wiring section 14L has a configuration in which a plurality of wirings are arranged in parallel to form a tape, such as an FFC (Flexible Flat Cable), and the lengths of the wirings are equal to each other. One end of the left wiring portion 14L is connected to the connector 13 mounted on the back surface of the left imaging board 12L, and the other end passes through a left through portion 41L (described later) of the left partition 40L and is mounted on the control board 20. Connected to the connector 21.

The control board 20 receives image signals captured by the left imaging unit 10L and the right imaging unit 10R, performs image processing based on the received image signals, and outputs a vehicle control signal. It is configured to have a recognition processing unit (not shown) and the like. The control board 20 is fixed to the housing 30 by, for example, screws.

筐体 As shown in FIG. 2, the housing 30 has an internal space composed of an upper housing 31 and a lower housing 32. The upper housing 31 and the lower housing 32 are formed by processing a metal plate into a predetermined shape, for example, and are joined to each other by welding, screwing, or the like. Inside the housing 30, a left-side partition (first partition) that partitions the internal space of the housing 30 into a left imaging board housing chamber S1 that houses the left imaging board 12L and a control board housing chamber S2 that houses the control board 20. (Partition part) 40L is provided.

The left partition 40L is formed of a rectangular metal plate, and is disposed inside the housing 30 so as to be orthogonal to the imaging direction of the left imaging unit 10L. The upper end of the left partition part 40L is fitted into a concave groove 31a provided in the ceiling of the upper housing 31, and the lower end is in contact with the lower housing 32 so as not to form a gap with the lower housing 32. (See FIG. 2). Although not shown, the left end and the right end of the left partition 40L are respectively fitted into concave grooves provided on the inner wall of the upper housing 31.

(2) As shown in FIG. 2, the front side of the internal space of the housing 30 is the left imaging board housing chamber S1 and the rear side is the control board housing chamber S2 with respect to the left partition 40L. Note that the left imaging substrate storage chamber S1 corresponds to a “first imaging substrate storage chamber” described in the claims.

The left partition 40L is provided with a left penetrating part (first penetrating part) 41L for communicating the left imaging substrate housing chamber S1 and the control substrate housing chamber S2 and passing the left wiring part 14L. As shown in FIGS. 2 and 6, the left through portion 41L is a rectangular through hole, and is formed at a position adjacent to the connector 21 of the control board 20 in the left partition portion 40L. By doing so, the length of the left wiring portion 14L can be shortened, so that the cost can be reduced. The left wiring portion 14L is arranged so as to pass through the left through portion 41L in a state where the width direction thereof substantially coincides with the left-right direction of the vehicle.

The dimensions of the left side penetrating portion 41L are based on the communication frequency communicated via the left side wiring portion 14L and the width of the left side wiring portion 14L so that the crosstalk between the left side imaging substrate 12L and the control substrate 20 is reduced. Stipulated. Specifically, for example, when the communication frequency communicated via the left wiring portion 14L is assumed to be 264 MHz, and the upper limit of the noise regulated by the stereo camera is 2 GHz, the ninth harmonic of 264 MHz (2.376 GHz) Need to be considered. When the frequency is 2.376 GHz, the wavelength is about 126 mm.

{Circle around (4)} When the width of the left wiring portion 14L is 19 mm, 1/4 wavelength = 31.5 mm and 1/8 wavelength = 16.8 mm as 1 / n wavelengths close to this. When the size of the left side penetrating portion 41L is close to the above wavelength, there is no effect of reducing the crosstalk, but if the size is between 31.5 mm and 16.8 mm, it is considered suitable for reducing the crosstalk. Since the intermediate value between 31.5 mm and 16.8 mm is about 24.2 mm, if the size of the left wiring portion 14L is 24 mm wide and 7 mm long, the diagonal length is 25 mm, and the above value (24. 2 mm), which has the effect of reducing crosstalk.

Note that the communication frequency (264 MHz) assumed here is merely an example, and the present invention is not limited to this. For example, when the communication frequency is f (MHz), if the size of the left side penetrating portion 41L is 4600 / f (mm) to 7900 / f (mm), it is considered that an effect of reducing crosstalk is exerted.
