Definitions
- the present invention relates to a technical field concerning an imaging device for a vehicle, a vehicle lamp, and an electronic control unit.
- a vehicular lamp includes a light source that emits light and a camera module that captures a predetermined area inside an outer casing that includes a light-transmitting cover and a housing (for example, Patent Document 1). reference).
- Such a vehicular lamp is used, for example, as a side turn signal lamp attached to both left and right sides of the vehicle body.
- An area from the rear to the side is photographed by the camera module, and the photographed image is displayed on a screen of a display arranged in the passenger compartment.
- the driver can recognize the situation of the area from the rear to the side by visually recognizing the left and right images displayed on the display screen, and can drive according to the grasped situation.
- the vehicular lamp Since such a vehicular lamp is provided, an area from the rear to the side is photographed by the camera module, so that a vehicle that does not require a side mirror can be manufactured. Since a predetermined area is photographed by the vehicular lamp, the vehicular lamp is also used as a vehicular imaging device.
- the outer shape tends to be large because the camera module is built in, but at least a part of the lamp is arranged to protrude to the outside of the vehicle body. Therefore, it is desired to reduce the size as much as possible in order to reduce the amount of protrusion from the vehicle body.
- the present invention aims to overcome the above-mentioned problems and to reduce the number of parts and reduce the size.
- a vehicular lamp includes an outer casing formed of a housing having an opening and a light-transmitting cover that closes the opening, a substrate disposed inside the outer casing, and an imaging device. And a camera module disposed on the substrate and a light emitting element provided as a light source and disposed on the substrate.
- the camera module and the light emitting element are arranged on the substrate arranged inside the outer casing.
- the camera module and the light emitting element are arranged on the same surface of the substrate.
- a pressing member disposed inside the outer casing and attached to the housing is provided, and the substrate is pressed against the housing by the pressing member. It is desirable to be positioned.
- the substrate is positioned with respect to the housing by attaching the pressing member to the housing.
- a part of the pressing member is provided as a light blocking part that blocks a part of the light emitted from the light emitting element.
- the pressing member for pressing and positioning the substrate relative to the housing also functions as a light blocking unit that blocks a part of the light emitted from the light emitting element.
- the effective incident region of the imaging light in the image sensor is formed in a shape having a longitudinal direction and a short direction, and the image sensor has a longitudinal length of the effective incident region. It is desirable to arrange the direction in the vertical direction.
- the optical axis of the camera module be inclined downward from the horizontal direction.
- the light-transmitting cover is formed with a transmission window through which photographing light incident on the camera module is transmitted, and the light-emitting element has the light-emitting element. It is desirable to provide a light shielding portion that shields the light that is emitted from the light and guided through the translucent cover from entering the transmission window.
- an imaging apparatus for a vehicle includes a camera module whose imaging range is a region from the rear side to a side including a part of a side surface of a vehicle body, and an image is captured on the screen by the camera module.
- the image is displayed on the screen, at least a part of the side surface is covered or obscured on the screen by the image distinguishing means so that the side surface and the part other than the side surface are visually distinguished. It is.
- a part of the photographing light incident on the camera module is controlled by the step so that the side surface and the part other than the side surface are visually distinguished.
- an image processing unit for processing an image photographed by the camera module is provided as the image distinguishing means.
- the side surface and the portion other than the side surface are visually distinguished by predetermined image processing by the image processing unit.
- another vehicular lamp according to the present invention further includes a light source in the vehicular imaging device.
- another vehicular imaging apparatus includes an outer casing formed of a housing having an opening and a light-transmitting cover that closes the opening, and an imaging device disposed inside the outer casing. And a nozzle having a discharge hole for discharging a fluid.
- the transmission cover is formed with a transmission window through which photographing light incident on the camera module is transmitted. It is facing the window.
- a light emitting element functioning as a light source for emitting light is disposed inside the outer casing.
- the light emitted from the light emitting element is irradiated to the outside.
- the housing and the nozzle are integrally formed.
- a water repellent treatment is performed on at least the outer surface of the light transmission cover.
- the fluid is discharged from the nozzle when the vehicle engine is started.
- the fluid is discharged from the nozzle at the time of input to the back gear of the vehicle.
- the camera module and the light emitting element are arranged on the substrate arranged inside the outer casing, the number of components is small, and the number of parts can be reduced and the size can be reduced.
- FIG. 5 is a sectional view taken along line VV in FIG. 3. It is an enlarged plan view of a housing. It is an enlarged rear view of a housing. It is a front view of a translucent cover. It is a vertical sectional view of a translucent cover. It is a horizontal sectional view of a translucent cover.
- FIG. 34 and FIG. 34 show the example in which the image process part was provided as an image discrimination means. It is a figure which shows the state before the process with respect to the side surface displayed on an image was performed, and the state by which the computer graphic image was superimposed on the side surface.
