Description
Technical Field
The present invention relates to an image pickup apparatus, and more particularly to an image pickup apparatus capable of moving a position of a lens barrel holding a lens in an optical axis direction.
Background
In recent years, in order to prevent accidents of automobiles and the like, a Driver Monitoring System (DMS) that monitors a state of a driver (such as a decrease in attention and a symptom of drowsiness) has been developed. As such a DMS, an imaging device that images a driver while illuminating the driver with light such as near-infrared light is known (for example, see patent document 1). Such an image pickup device is often embedded in a decorative part such as an instrument panel or an instrument panel of an automobile, but it is required to be as compact as possible so as not to affect the design of a vehicle interior.
In such an imaging device, a male screw formed in a lens barrel that holds a lens is screwed into a female screw formed in a housing, whereby the position of the lens barrel can be moved in the optical axis direction to adjust the focal position. In a conventional imaging apparatus, a lens barrel is moved in an optical axis direction by holding the lens barrel from an outer peripheral side with a jig and rotating the lens barrel.
However, in such a conventional imaging apparatus, since the lens barrel needs to be held by the jig from the outer peripheral side, a space for inserting the jig into the periphery of the lens barrel is required. Therefore, the size of the housing, particularly the size in the height direction, cannot be sufficiently reduced, and it is difficult to make the imaging apparatus compact.

Detailed Description
Hereinafter, an embodiment of the imaging device of the present invention will be described in detail with reference to fig. 1 to 7. In fig. 1 to 7, the same or corresponding components are denoted by the same reference numerals, and overlapping description thereof is omitted. In fig. 1 to 7, the scale and size of each component may be exaggerated, and some components may be omitted. In the following description, unless otherwise specified, terms such as "1 st" and "2 nd" are used only to distinguish constituent elements from each other, and do not indicate a specific order or sequence.
Fig. 1 is a perspective view showing an image pickup apparatus 1 according to an embodiment of the present invention. The case where the imaging device 1 in the present embodiment is an imaging device used in the Driver Monitoring System (DMS) as described above will be described, but the imaging device of the present invention can of course be used for other applications.
As shown in fig. 1, the image pickup apparatus 1 includes a housing 4 including a front housing 2 and a rear housing 3, and 2 LEDs (light emitting diodes) 12 as a light source for emitting near-infrared light and a lens barrel 20 holding at least one lens 22 therein are housed in the housing 4. In fig. 1, the sealing sheet member and the cover member, which will be described later, are not shown for ease of understanding. In the present embodiment, for convenience, the + Y direction in fig. 1 is referred to as "front" or "front", and the-Y direction is referred to as "rear" or "rear".
Fig. 2 is an exploded perspective view of the image pickup apparatus 1, fig. 3 is a vertical sectional view, and fig. 4 is a horizontal sectional view. As shown in fig. 2 to 4, a 1 st circuit board 30 on which an image pickup element 32 is mounted, a 2 nd circuit board 10 on which an LED12 is mounted, and an LED connector 41 and a camera connector 42 mounted on the 1 st circuit board 30 are housed between the front case 2 and the rear case 3 of the image pickup apparatus 1. A waterproof and dustproof sealing member 43 is disposed around the LED connector 41. The rear case 3 is fixed to the front case 2 by screws 52, and a seal member 44 is disposed between the front case 2 and the rear case 3 along the outer peripheries of the front case 2 and the rear case 3. Further, a shield member 45 for reducing signal noise is disposed inside the rear case 3.
The rear case 3 is formed with a connector opening 50 into which the LED connector 41 is inserted, and the LED connector 41 is inserted and housed in the connector opening 50. As shown in fig. 4, the rear end portion of the LED connector 41 protrudes from the rear case 3 to be exposed to the outside. A counterpart connector (not shown) can be connected to the LED connector 41 from the rear of the rear case 3, and a control signal can be input to the LED12 through the LED connector 41.
The rear case 3 has a cylindrical portion 51 extending rearward (-Y direction), and the camera connector 42 is inserted and housed in the cylindrical portion 51. A counterpart connector (not shown) can be connected to the camera connector 42 from behind the rear case 3, and a signal obtained by the image pickup device 32 is output to the outside through the camera connector 42.
As shown in fig. 2 to 4, the 1 st circuit board 30 and the 2 nd circuit board 10 extend entirely in the X direction (width direction), respectively. The 2 nd circuit board 10 is disposed in front of the 1 st circuit board 30 (+ Y direction side), and the 2 LEDs 12 mounted on the 2 nd circuit board 10 are connected to the LED connector 41 mounted on the 1 st circuit board 30 by wires 46. The 2 nd circuit board 10 is fixed to the front case 2 by screws 47.
As shown in fig. 2, a lens barrel housing section 24 for housing the lens barrel 20 is formed substantially at the center in the width direction of the front surface 2A of the front case 2, and window sections (openings) 26 are formed on both sides in the width direction with the lens barrel housing section 24 interposed therebetween. The barrel housing 24 has a female screw portion 24A therein. As described above, in the present embodiment, the lens barrel housing portions 24 and the window portions 26 are formed in the front surface 2A of the front case 2 in an aligned manner in the width direction.
Fig. 5A is a front view of the lens barrel 20, and fig. 5B is a plan view. As shown in fig. 5A and 5B, the lens barrel 20 includes 1 or more lenses 22 and a lens barrel 23 that holds the lenses 22. In the cross-sectional views of fig. 3 and 4, for the sake of simplicity, a plurality of lenses are schematically illustrated as 1 lens 22.
The lens barrel 23 includes: an external thread portion 81 screwed with the internal thread portion 24A of the barrel housing portion 24 of the front housing 2; and a flange portion 82 located forward of the male screw portion 81. The flange portion 82 has a diameter larger than that of the male screw portion 81. The lens barrel 20 is mounted inside the barrel housing 24 of the front housing 2 by screwing the male screw portion 81 of the lens barrel 20 into the female screw portion 24A of the barrel housing 24 of the front housing 2.
The lens barrel 23 has 2 extending pieces 83 extending forward from the outer peripheral edge of the front edge portion of the flange 82. These extending pieces 83 are arranged so as to be separated from each other in the circumferential direction, and a groove 84 is formed between 2 extending pieces 83. In the present embodiment, the 2 extending pieces 83 are arranged in plane symmetry with respect to the YZ plane, and the 2 grooves 84 are located at positions rotated by 180 degrees around the optical axis of the lens 22.
A jig (not shown) such as a straight screwdriver, for example, can be inserted into the groove 84 formed between the extending pieces 83. Therefore, the lens barrel 20 can be moved in the Y direction (optical axis direction) by inserting the jig into the groove 84 and rotating the lens barrel 23 through the screwing of the male screw portion 81 of the lens barrel 23 and the female screw portion 24A of the barrel housing portion 24. By moving the lens barrel 20 in the Y direction in this way, the focal position of the image obtained by the imaging device 32 can be adjusted.
As described above, in the present embodiment, since the jig can be inserted into the groove formed between the extension pieces 83 of the lens barrel 23 to rotate the lens barrel 20, it is not necessary to secure a space for attaching the jig around the lens barrel 20 as in the conventional imaging device. Therefore, the size of the front case 2, particularly the size in the height direction, can be made smaller than that of the conventional imaging apparatus, and the imaging apparatus 1 can be made compact.
The LED12 mounted on the 2 nd circuit board 10 is located behind the window portion 26 of the front case 2. With such a configuration, light (illumination light) from the LED12 can be emitted through the window portion 26 of the front case 2 to illuminate an object to be photographed (for example, a driver). As described above, in the present embodiment, the image can be captured by the imaging element 32 while being illuminated by the light from the LED12, and therefore, a higher quality image can be obtained.
Returning to fig. 1, front case 2 has a convex portion 27 protruding forward (+ Y direction) from front surface 2A. The convex portion 27 extends in a substantially コ shape so as to surround the lower and lateral sides of the lens barrel housing portion 24 and the window portion 26. The seal piece member 62 and the cover member 60 as shown in fig. 2 are disposed in an area surrounded by the three sides by the convex portions 27.
The cover member 60 covers the front of the lens barrel housing portion 24 and the window portion 26 of the front case 2, and is formed of a material that transmits light emitted from the LED 12. In the present embodiment, since the near-infrared light is emitted from the LED12 and the image of the near-infrared light is acquired in the image pickup device 32, a visible light cut filter can be used as the cover member 60 in order to reduce the influence of the visible light on the image acquired by the image pickup device 32.
The sealing sheet member 62 is made of a material having water-proof and dust-proof properties, and an opening 62A is formed in a portion corresponding to the lens barrel housing portion 24 and the window portion 26 of the front case 2. That is, the sealing sheet member 62 has a shape surrounding the barrel housing portion 24 and the window portion 26 of the front case 2. By disposing such a sealing sheet member 62 so as to surround the lens barrel housing 24 and the window 26 of the front case 2 and disposing the cover member 60 on the front surface, it is possible to suppress entry of water or dust from the outside into the LED12 located behind the lens barrel 20 and the window 26 in the lens barrel housing 24.
The sealing sheet member 62 is preferably a double-sided adhesive tape. By configuring the sealing sheet member 62 with a double-sided tape, the cover member 60 can be attached to the front surface 2A of the front case 2 via the sealing sheet member 62.
In the present embodiment, since the convex portion 27 protruding forward from the front surface 2A of the front case 2 is disposed so as to surround the lower and lateral sides of the lens barrel housing portion 24 and the window portion 26, when the seal sheet member 62 and the cover member 60 are disposed on the front surface 2A of the front case 2, the seal sheet member 62 and the cover member 60 can be positioned by bringing the seal sheet member 62 and the cover member 60 into contact with the convex portion 27.
As shown in fig. 3 and 4, the image pickup device 32 is disposed on a surface on which light passing through the lens 22 of the lens barrel 20 is focused, and is configured to receive the light passing through the lens 22. As shown in fig. 3, the central axis (optical axis) P of the lens barrel 20 is located above the center between the upper surface 2B and the lower surface 2C of the front case 2. That is, the central axis P of the lens barrel 20 is located closer to the upper surface 2B than the lower surface 2C of the front case 2. When the image pickup apparatus 1 is embedded in a decorative portion such as an instrument panel or an instrument panel in a vehicle, a portion other than the lens barrel 20 can be embedded in the decorative portion. Therefore, by disposing the lens barrel 20 in the front housing 2 so as to be close to the upper side, the height of the image pickup device 1 protruding from the decorative portion can be reduced. This can reduce the influence of the imaging device 1 on the design of the vehicle interior.
Fig. 6 is a front view showing the 2 nd circuit board 10. As shown in fig. 6, in the present embodiment, 2 LEDs 12(12A, 12B) are mounted on 1 circuit board 10. Since the plurality of LEDs 12 are mounted on 1 circuit board in this manner, the wiring for each LED12 can be shared, and therefore, the wiring pattern inside the circuit board can be reduced, and the circuit board can be downsized. In addition, the wires 46 for connecting the 1 st circuit board 30 mounted with the LED connector 41 and the respective LEDs 12 also need only 2 of the + pole and the-pole. In addition, as in the present embodiment, the use of the plurality of LEDs 12A, 12B can increase the amount of light (illumination light) emitted from the imaging device 1, and therefore, a higher quality image can be obtained in the imaging element 32.
As shown in fig. 6, the 2 nd circuit board 10 has a substantially U-shaped shape, and includes a light source mounting portion 71A on which the LED 12A is mounted, a light source mounting portion 71B on which the LED 12B is mounted, and a connecting portion 72 that connects the 2 light source mounting portions 71A, 71B to each other. The dimension of the coupling portion 72 in the height direction (Z direction) is smaller than the dimension of the light source mounting portions 71A, 71B in the height direction, and the coupling portion 72 extends in the width direction below the lens barrel 20. Thus, a barrel insertion space S into which the lens barrel 20 is inserted is formed above the connection portion 72, and the connection portion 72 connects the light source mounting portions 71A and 71B to each other while avoiding the lens barrel 20.
In this way, since the connection portion 72 of the 2 nd circuit board 10 connects the light source mounting portions 71A and 71B so as to avoid the lens barrel 20, the plurality of LEDs 12A and 12B can be mounted without increasing the size of the 2 nd circuit board 10 in the height direction (Z direction). Therefore, the amount of light (illumination light) emitted from the imaging device 1 can be increased while the 2 nd circuit board 10 and the imaging device 1 are downsized.
In the above-described embodiment, the example in which 2 LEDs 12 are mounted on the 2 nd circuit board 10 has been described, but only 1 LED12 may be mounted on the 2 nd circuit board 10, or 3 or more LEDs may be mounted. When 2 or more LEDs 12 are mounted on the 2 nd circuit board 10, the LEDs 12 are preferably arranged on both sides in the width direction of the lens barrel 20.
In the above-described embodiment, the example in which 2 extending pieces 83 are provided in the lens barrel 23 and 2 grooves 84 are formed has been described, but the number of extending pieces 83 and grooves 84 is not limited to this, and 3 or more extending pieces 83 may be provided in the lens barrel 23 and 3 or more grooves 84 may be formed.
The terms "upper", "lower", "above", "below", "upper", "lower", "front", "rear", "width direction", "height direction", and other terms indicating positional relationships used in the present description are used only for specifying relative relationships between elements in association with the illustrated embodiments, and do not specify absolute positional relationships. Therefore, it should be noted that if the position or orientation of the image pickup apparatus 1 changes, the direction indicated by these terms also changes accordingly. For example, as in the imaging device 1A of fig. 7, the imaging device 1 may be embedded in the instrument panel 100 between the driver seat D and the passenger seat Q of the automobile, and in this case, "up" and "up" may mean vertically upward and "down" may mean vertically downward. Alternatively, the imaging device 1 may be embedded in the roof portion 102 of the automobile as in the imaging device 1B of fig. 7, and in this case, the "upper" and the "upper" may be vertical and the "lower" may be vertical and upper. The LED12 of the imaging device 1 is irradiated with infrared rays, for example, toward the driver's seat D, and the state of the driver is analyzed from the image of the driver captured by the imaging element 32 through the lens 22.
As described above, according to one aspect of the present invention, there is provided an image pickup apparatus capable of moving a lens barrel in an optical axis direction with a compact configuration. The imaging device includes: a housing having a lens barrel housing section with an internal thread section formed on a front surface thereof; and a lens barrel which can be mounted inside the barrel housing section of the housing. The lens barrel has at least one lens and a lens barrel holding the at least one lens. The imaging device further includes an imaging element that receives light that has passed through the at least one lens of the lens barrel. The lens barrel of the lens barrel includes: an external thread portion screwed with the internal thread portion of the lens barrel housing portion of the housing; a flange portion located in front of the male screw portion, the flange portion having a diameter larger than a diameter of the male screw portion; and a plurality of extension pieces extending forward from an outer peripheral edge of a front end portion of the flange portion. The plurality of extending pieces are separated from each other in the circumferential direction.
According to this configuration, since the groove into which the jig can be inserted is formed between the extension pieces provided at the front edge of the lens barrel, the jig can be inserted into the groove, and the lens barrel can be rotated. Thus, the lens barrel can be moved in the optical axis direction by screwing the male screw portion of the lens barrel with the female screw portion of the barrel housing. Therefore, it is not necessary to secure a space around the lens barrel for mounting a jig for rotating the lens barrel. Therefore, the size of the housing, particularly the size in the height direction, can be made smaller than that of the conventional imaging apparatus, and the imaging apparatus can be made compact.
Preferably, the central axis of the lens barrel is located closer to the upper surface than the lower surface of the housing. For example, when the image pickup device is embedded in a decorative portion such as an instrument panel or an instrument panel in a vehicle, since a portion other than the lens barrel can be embedded in the decorative portion, the height of the image pickup device protruding from the decorative portion can be reduced by disposing the lens barrel in the housing so as to be close to the upper side. Therefore, the influence of the imaging device on the design of the vehicle interior can be reduced.
The imaging device may further include: a sealing sheet member disposed on the front surface of the housing so as to surround the lens barrel housing portion; and a cover member disposed on a front surface of the sealing sheet member. By disposing such a seal member so as to surround the lens barrel housing portion and disposing the cover member on the front surface of the seal member, it is possible to suppress entry of water or dust from the outside into the lens barrel in the lens barrel housing portion.
The housing may have a projection projecting forward from the front surface of the housing. The convex portion may extend so as to surround the lower and lateral sides of the lens barrel housing portion. When such a projection is provided, the seal sheet member and the cover member can be positioned by bringing the seal sheet member and the cover member into contact with the projection when the seal sheet member and the cover member are disposed on the front surface of the housing.
The image pickup apparatus may further include at least one light source that emits light through the at least one window portion of the housing. The seal member may be disposed on the front surface of the housing so as to surround the lens barrel housing section and the at least one window section. With this configuration, it is possible to capture an image while illuminating it with light from the light source, and therefore it is possible to obtain a higher-quality image in the image pickup device. Further, by disposing the seal member so as to surround the lens barrel housing section and the window section, it is possible to suppress entry of water or dust from the outside into the light source located behind the lens barrel and the window section in the lens barrel housing section.
While the preferred embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and may be implemented in various different forms within the scope of the technical idea.
