Description

[Technical field]

[0001] The present invention relates to a digital mirror and a digital mirror system including the digital mirror. [Background technology]

[0002] Conventionally, there is known a digital mirror that is attached to a room mirror provided in a vehicle interior so as to cover the mirror surface and is capable of displaying an image of the outside of the vehicle on a display. As a technology related to the digital mirror, for example, the one disclosed in Patent Document 1 is known.

[0003] Patent Document 1 discloses a technology that makes a rear camera that captures images of the area behind a vehicle and obtains captured images by attaching the rear camera to the back side of a digital mirror, making the rear camera less visible to occupants (see Figures 1 and 2 of Patent Document 1, etc.).

[0004] In the above-mentioned Patent Document 1, the digital mirror is attached to a rearview mirror installed in the vehicle cabin by holding the rearview mirror in the vertical direction with a pair of gripping pieces arranged vertically on the back side of the digital mirror (see Figure 3 of Patent Document 1, etc.).

[0005] [Patent Document 1] JP 2020-23327 A Summary of the Invention [Problem to be solved by the invention]

[0006] In the conventional digital mirrors described above, when a driver or other occupant wanted to adjust the brightness of the captured image shown on the display, the driver could adjust it appropriately by operating a button provided on the main body of the digital mirror.

[0007] Regarding brightness adjustment of the captured image, it is conceivable to give a conventional digital mirror as described above a function capable of detecting brightness and controlling the brightness of the captured image displayed on the display based on the detected brightness, thereby automatically adjusting the brightness of the captured image instead of manual operation by the user.

[0008] However, when attempting to provide a functional unit capable of detecting brightness (e.g., a brightness sensor) in a conventional digital mirror as described above, there was no space available on the periphery of the conventional digital mirror to accommodate the functional unit, making it difficult to arrange the brightness sensor.

[0009] To address the above problem, it is possible to secure the installation space by providing a brightness sensor near the front camera on the rear side of the conventional digital mirror. However, in this case, since the brightness sensor is provided on the rear side of the digital mirror, it is affected by the ambient light through the windshield, making it difficult to detect the brightness on the display side.

[0010] In addition, since conventional digital mirrors are installed so as to overlap the rear-view mirror, the rear-view mirror gets in the way and there is no space behind the digital mirror to place a brightness sensor. To address the above problem, it is possible to make the size of the digital mirror larger than the rear-view mirror when viewed in a plan view. However, when this solution is adopted, there are problems such as the size of the applicable rear-view mirror being limited and the digital mirror interfering with the sun visor.

[0011] Another solution to the above problems is to completely replace the rearview mirror with a digital mirror. This solution makes it possible to place a brightness sensor on the back of the digital mirror. However, when this solution is adopted, it is necessary to attach the digital mirror later, which causes problems such as cumbersome work and limits the types of vehicles to which it can be applied.

[0012] The present invention has been made in consideration of the above-mentioned circumstances, and has an object to provide a digital mirror that enables more accurate brightness adjustment of a captured image by detecting the brightness on the display side, and a digital mirror system equipped with this digital mirror.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0031] Hereinafter, first to sixth embodiments of the present invention will be described.

[0032] A first embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a schematic diagram of a vehicle equipped with a digital mirror system having a digital mirror according to a first embodiment of the present invention, FIG. 2 is a perspective view showing the digital mirror as viewed from the front side, FIG. 3 is a perspective view showing the digital mirror as viewed from the back side, FIG. 4 is a cross-sectional view taken along line AA shown in FIG. 3, FIG. 5 is a diagram showing the digital mirror attached to a rearview mirror, and FIG. 6 is a diagram showing the digital mirror placed on a dashboard.

[0033] <Overall configuration of the digital mirror system> The digital mirror system 100 shown in Fig. 1 is a system that includes a digital mirror 1 and a camera 2, and displays an image (video) of the outside of the vehicle captured by the camera 2 on the digital mirror 1. In this embodiment, a passenger car is exemplified as the vehicle V, but other vehicles such as a bus or truck may also be used. The digital mirror system 100 may be retrofittable to the vehicle V.

[0034] The camera 2 used in the digital mirror system 100 is an imaging device that captures an image of the outside of the vehicle V, acquires the captured image, and transmits the acquired captured image to the digital mirror 1, and corresponds to the "imaging means" described in the claims. The camera 2 may be, for example, an optical camera. The camera 2 is capable of transmitting the acquired captured image to the digital mirror 1 by wired or wireless communication, and transmits the captured image to the digital mirror 1 immediately after acquiring the captured image (i.e., in real time).

[0035] <About the camera> In this embodiment, the camera 2 is provided, for example, on the upper part of the rear window in the vehicle V, and captures the rear of the vehicle V. In this case, the digital mirror system 100 is a system that displays an image of the rear of the vehicle V on the digital mirror 1, thereby allowing the occupant to know the situation behind the vehicle V. The fan-shaped area R shown by the dashed line in FIG. 1 is a schematic example of an area captured as a captured image by the camera 2. The camera 2 may use a so-called wide-angle lens. The camera 2 may be disposed, for example, at the rear end of the vehicle V (above the rear license plate, etc.). The camera 2 may be provided at the front of the vehicle V to capture the front of the vehicle V, or may be provided at the side of the vehicle V to capture the side of the vehicle V. The camera 2 may be provided outside the vehicle V or may be provided inside the vehicle V. A plurality of cameras 2 may be provided to obtain captured images of a plurality of areas.

[0036] <About Digital Mirror> 1 to 6 is a device capable of displaying on a display DS an image of the rear (exterior) of a vehicle V. The digital mirror 1 is capable of receiving an image from a camera 2, for example. Note that the digital mirror 1 may obtain an image by any means other than receiving the image from the camera 2. The digital mirror 1 may be a so-called drive recorder capable of storing the obtained image in a storage medium.

[0037] The digital mirror 1 is attached to the rearview mirror M of the vehicle V so as to cover the mirror surface. The above-mentioned "rearview mirror" refers to a mirror that is provided, for example, near the overhead of the driver's seat of the vehicle V, to allow a passenger sitting in the driver's seat to indirectly see the rear of the vehicle V. The rearview mirror M includes a mirror body part Ma that is the main part to which the mirror is attached and is long in the width direction D2, and a mirror arm part Mb that connects the mirror body part Ma to the vehicle V (specifically, the ceiling, the windshield, etc.). The orientation of the mirror body part Ma can be changed with respect to the mirror arm part Mb, centering on the connection point.

[0038] The above phrase "covering the mirror surface" means that the digital mirror 1 overlaps at least a portion of the mirror attached to the mirror main body Ma when viewed from the mirror surface side of the mirror. In other words, when attached to the rearview mirror M, the digital mirror 1 may cover the entire mirror surface or may not cover a portion of the mirror surface. Also, when attached to the rearview mirror M, the digital mirror 1 may or may not be in contact with the mirror surface.

[0039] The digital mirror 1 comprises a main body 10, an upper gripping piece 18, a lower gripping piece 19, a binding part 20, and a brightness sensor 21. Each component of the digital mirror 1 will be described below.

[0040] <About the main unit> The main body 10 constitutes the main body of the digital mirror 1. The main body 10 displays the captured image captured by the camera 2. The main body 10 is a thin, roughly rectangular parallelepiped shape that is long in the width direction D2. As described below, the upper gripping piece 18 and the lower gripping piece 19 are provided on the rear surface 10b of the main body 10 on the vehicle front side (i.e., the side opposite the driver's seat) when the digital mirror 1 is attached to the rearview mirror M. The main body 10 has a display device section 11, a base section 12, a wall section 13, an upper plate-shaped section 14, an upper buffer section 15, a lower plate-shaped section 16, and a lower buffer section 17.

[0041] The display device section 11 is a portion in which a display DS is provided on the front surface 10a opposite to the back surface 10b of the main body section 10. The display device section 11 is configured to include a display DS, various devices for controlling the display DS, and a housing that houses the various devices. The display DS may be, for example, an LCD (Liquid Crystal Display). The display DS occupies most of the surface on the front surface 10a side of the housing (i.e., the surface on the front surface 10a side of the display device section 11), and preferably occupies 90% or more of the area of ​​the surface, more preferably 95% or more of the area of ​​the surface, and even more preferably 98% or more of the area.

[0042] The "various devices for controlling the display DS" include a brightness control unit (not shown). The "brightness control unit" corresponds to a "brightness control means" capable of controlling the brightness of a captured image displayed on the display DS based on the brightness detected by a brightness sensor (brightness detection means) 21, which will be described later.

[0043] The display device unit 11 is generally rectangular parallelepiped-shaped, and its upper surface in the vertical direction D1 forms an upper end surface 11a. The upper end surface 11a extends substantially horizontally. A base portion 12, which will be described later, is provided on the upper end surface 11a. The display device unit 11 is also configured such that its lower surface in the vertical direction D1 forms a lower end surface that extends substantially horizontally, and both end surfaces in the width direction D2 form one end surface and the other end surface that extend substantially vertically. The display device unit 11 is also configured such that its rear surface 10b forms a rear surface that extends substantially vertically. When the digital mirror 1 is attached to the rearview mirror M, the rear surface of the display device unit 11 faces the mirror surface of the rearview mirror M.

[0044] The display device unit 11 includes an outlet C on an upper end surface 11a of the display device unit 11 into which a plug (not shown) can be inserted and removed in the up-down direction D1. The above-mentioned "plug" refers to a cord that electrically connects between the digital mirror 1 and an external device and a terminal portion of the cord. The plug includes a cable as a cord. The plug may be for supplying power to the display device unit 11 of the digital mirror 1, or for transmitting and receiving control signals between the display device unit 11 of the digital mirror 1. In this embodiment, the display device unit 11 includes three outlets C arranged in the width direction D2. The shape of the outlets C may conform to a predetermined standard.

[0045] The base 12 is a structural part that protrudes upward from the upper end surface 11a of the display device 11. The base 12 is fixed to the upper end surface 11a of the display device 11. The base 12 may be formed to be equal to or higher than the height in the vertical direction D1 of the plug P to be inserted into the outlet C. For example, the base 12 preferably has a height of 1 cm or more, more preferably 1.5 cm or more, and even more preferably 2 cm or more in the vertical direction D1. The base 12 may be molded integrally with the upper end surface 11a of the display device 11 (i.e., the housing).

[0046] Two pedestal portions 12 are provided on the upper end surface 11a of the display device unit 11, spaced apart from each other in the width direction D2. Each pedestal portion 12 is provided at an equal distance from one end 11b and the other end 11c of the display device unit 11 in the width direction D2. That is, each pedestal portion 12 is provided at a position symmetrical to each other on the upper end surface 11a of the display device unit 11. Each pedestal portion 12 has a rectangular parallelepiped shape, and the upper surface thereof is formed in a substantially flat shape. Note that each pedestal portion 12 does not have to be provided at a position symmetrical to each other. Also, one or three or more pedestal portions 12 may be provided. In that case, the upper plate-shaped portion 14 and the upper buffer portion 15, as well as the upper gripping piece 18, which will be described later, may be provided in a number corresponding to the number of pedestal portions 12.

[0047] The wall portion 13 is a thin plate-like structure extending upward from the display device portion 11 along the surface 10a of the main body portion 10. The wall portion 13 is provided so as to cover at least a part of the base portion 12 from the surface 10a side. The above phrase "covering at least a part of the base portion from the surface side" means that the wall portion 13 overlaps at least a part of the base portion 12 when viewed from the surface 10a side of the main body portion 10. Here, the wall portion 13 covers the entire base portion 12 from the surface 10a side. Therefore, the wall portion 13 is formed to be equal to or higher than the height of the base portion 12 in the vertical direction D1.

[0048] The wall portion 13 is provided in a range extending from one end 11b to the other end 11c in the width direction D2 of the display device unit 11. In other words, the wall portion 13 is provided over the entirety of the display device unit 11 in the width direction D2. More specifically, the wall portion 13 is formed to a constant height over the entirety of the display device unit 11 in the width direction D2.

[0049] The wall portion 13 may be bent from one end 11b in the width direction D2 of the display device portion 11 to fit along the side surface of the display device portion 11, and extend to a position corresponding to the back surface 10b of the main body portion 10. Similarly, the wall portion 13 may be bent from the other end 11c in the width direction D2 of the display device portion 11 to fit along the side surface of the display device portion 11, and extend to a position corresponding to the back surface 10b of the main body portion 10. The wall portion 13 may be formed such that both portions bent along the side surface of the display device portion 11 have the same height as other portions (i.e., portions along the front surface 10a of the display device portion 11).

[0050] In this embodiment, as described above, the wall portion 13 formed along the side surface of the display device unit 11 is provided, but the present invention is not limited to this configuration, and a configuration in which the wall portion 13 formed along the side surface of the display device unit 11 is omitted may be adopted. In other words, the wall portion 13 may be provided only in a range from one end 11b to the other end 11c in the width direction D2 of the display device unit 11.

[0051] The wall portion 13 is connected to the base portion 12. In other words, the wall portion 13 contacts at least a part of the base portion 12 from the surface 10a side, and they are fixed to each other. The wall portion 13 is provided flush with the surface of the display device portion 11 on the surface 10a side (i.e., the surface of the display device portion 11). The above "flush" means that there is no step between the surfaces of each portion, or the step is sufficiently small. The wall portion 13 may be molded integrally with the base portion 12. The wall portion 13 may be provided so that the boundary with the display device portion 11 is not visible when viewed from the surface 10a side.

[0052] More specifically, the wall 13 is provided in a range including a position corresponding to the outlet C in the width direction D2 of the display device 11. In particular, the wall 13 is provided so as to cover the plug inserted into the outlet C from the front surface 10a side. That is, the wall 13 is formed to be equal to or higher than the height of the plug in the vertical direction D1. The wall 13 may be provided at the same height as the base 12. Therefore, the wall 13 preferably has a height of 1 cm or more, more preferably 1.5 cm or more, and even more preferably 2 cm or more in the vertical direction D1. The wall 13 may be formed integrally with the display device 11 (i.e., the housing).

[0053] The wall 13 may have an arbitrary mark 13a on the surface 10a side. The mark 13a may be, for example, a logo mark representing the manufacturer of the digital mirror 1, a pattern or design, or information that should be known to the occupant (for example, information warning of danger). This makes it possible to provide predetermined information to the occupant and improve the aesthetics of the digital mirror 1.

[0054] A camera, a speaker, or various sensors may be provided on wall 13. For example, in the case where a camera for capturing an image of the interior of the vehicle or the rear of the vehicle is provided on wall 13, a camera body may be disposed on rear surface 10b side of wall 13, and an opening may be formed in wall 13 at a position corresponding to the image capturing direction of the camera body. In the case where a speaker is provided on wall 13, a diaphragm of the speaker may be attached to at least a part of wall 13, and at least a part of wall 13 itself may function as a diaphragm of the speaker.

[0055] The wall 13 is formed so that the brightness sensor 21 described later can receive light from the display DS side. Specifically, a through hole 13b is formed in the wall 13 at a position where the brightness sensor 21 can receive light from the display DS side. The through hole 13b may be an opening formed penetrating from the front surface 10a side of the wall 13 to the back surface 10b side of the wall 13, and the opening may be covered or blocked with a light-transmitting material.

[0056] The upper plate-shaped portion 14 is a structure for holding an upper buffer portion 15 and an upper gripping piece 18, which will be described later. The upper plate-shaped portion 14 is a thin plate-shaped member provided on the rear surface 10b side across at least a part of the display device portion 11 and the base portion 12. The upper plate-shaped portion 14 is provided at a position corresponding to each base portion 12. In other words, a pair of upper plate-shaped portions 14 are provided on the upper portion of the rear surface 10b side of the digital mirror 1.

[0057] The upper buffer section 15 is a buffer material provided below the upper gripping piece 18 on the back surface 10b of the main body section 10. Specifically, the upper buffer section 15 is provided below the upper gripping piece 18 on the surface of the upper plate-shaped section 14. The upper buffer section 15 is configured such that the contact surface section 15a of the upper buffer section 15 abuts against the mirror body section Ma of the rearview mirror M when the digital mirror 1 is attached to the rearview mirror M. For example, the upper buffer section 15 may abut against the mirror surface of the mirror body section Ma. The size (area and height) of the upper buffer section 15 can be set arbitrarily according to the shape of the rearview mirror M to which the digital mirror 1 is to be attached, etc.

[0058] The lower plate-shaped portion 16 is a structure for holding a lower buffer portion 17 and a lower gripping piece 19, which will be described later. The lower plate-shaped portion 16 is a thin plate-shaped member provided on at least a part of the display device portion 11 on the rear surface 10b side. The lower plate-shaped portions 16 are provided below the base portion 12. In other words, a pair of lower plate-shaped portions 16 are provided on the lower portion of the rear surface 10b of the digital mirror 1.

[0059] The lower buffer section 17 is a buffer material provided above the lower gripping piece 19 on the back surface 10b of the main body section 10. Specifically, the lower buffer section 17 is provided above the lower gripping piece 19 on the surface of the lower plate-shaped section 16. The lower buffer section 17 is made of a material such as rubber. The lower buffer section 17 is configured such that the contact surface section 17a of the lower buffer section 17 abuts against the mirror main body section Ma of the rearview mirror M when the digital mirror 1 is attached to the rearview mirror M. For example, the lower buffer section 17 may abut against the mirror surface of the mirror main body section Ma. The size (area and height) of the lower buffer section 17 can be set arbitrarily according to the shape of the rearview mirror M to which the digital mirror 1 is to be attached, etc.

[0060] <About the upper gripping piece> The upper gripping piece 18 is a thin plate-like member erected on the upper end 10c side of the back surface 10b of the main body 10. The upper gripping piece 18 is erected on the base 12. The upper gripping piece 18 extends substantially horizontally from the base 12, and at its tip is curved upward by approximately 180 degrees to form a hook shape. The above-mentioned "standing on the base" includes not only the case where the upper gripping piece 18 is directly provided on the base 12, but also the case where the upper gripping piece 18 is indirectly provided on the base 12 via a separate member. Here, the upper gripping piece 18 is erected on the base 12 via the upper plate-like portion 14. The base end 18a of the upper gripping piece 18 is connected to the base 12 (here, the upper plate-like portion 14), and the tip end 18b opposite to the base end 18a is a free end. The upper gripping piece 18 is capable of hooking a binding part 20, which will be described later, on a curved part on the side of the tip part 18b.

[0061] The upper gripping piece 18 is provided above the upper buffer portion 15 on the surface of the upper plate-shaped portion 14. More specifically, the upper gripping piece 18 is located at the upper end portion 12a of the base portion 12. The upper gripping piece 18 has flexibility at least in the vertical direction D1. The upper gripping piece 18 cooperates with the lower gripping piece 19 to grip the mirror body portion Ma of the rearview mirror M in the vertical direction D1. In other words, when the digital mirror 1 is attached to the rearview mirror M, the mirror body portion Ma of the rearview mirror M is located on the lower surface side of the upper gripping piece 18.

[0062] <About the lower gripping piece> The lower grip piece 19 is a thin plate-like member erected on the lower end 10d side of the back surface 10b of the main body 10. The lower grip piece 19 is erected on the display device 11. The lower grip piece 19 extends substantially horizontally from the display device 11, and at its tip is curved downward by approximately 180 degrees to form a hook shape. The above-mentioned "standing on the display device" includes not only the case where the lower grip piece 19 is directly provided on the display device 11, but also the case where the lower grip piece 19 is indirectly provided on the display device 11 via a separate member. Here, the lower grip piece 19 is erected on the display device 11 via the lower plate-like portion 16. The lower grip piece 19 has a base end portion 19a connected to the display device 11 (here, the lower plate-like portion 16), and a tip portion 19b opposite to the base end portion 19a is a free end. The lower gripping piece 19 is capable of hooking a binding part 20, which will be described later, on a curved part on the side of the tip part 19b.

[0063] The lower gripping piece 19 is provided below the lower buffer portion 17 on the surface of the lower plate-shaped portion 16. More specifically, the lower gripping piece 19 is located at the lower end portion 11d of the display device portion 11. The lower gripping piece 19 has flexibility at least in the vertical direction D1. The lower gripping piece 19 cooperates with the upper gripping piece 18 to grip the mirror body portion Ma of the rearview mirror M in the vertical direction D1. In other words, when the digital mirror 1 is attached to the rearview mirror M, the mirror body portion Ma of the rearview mirror M is located on the upper surface side of the lower gripping piece 19.

[0064] <About the binding part> The binding part 20 is a member for binding the upper grip piece 18 and the lower grip piece 19 when the digital mirror 1 is attached to the rearview mirror M. The binding part 20 is bridged between the vicinity of the tip 18b of the upper grip piece 18 and the vicinity of the tip 19b of the lower grip piece 19, and generates a biasing force that brings the upper grip piece 18 and the lower grip piece 19 closer to each other. For example, the binding part 20 binds the upper grip piece 18 and the lower grip piece 19 by being hooked on each of a curved part formed on the tip 18b side of the upper grip piece 18 and a curved part formed on the tip 19b side of the lower grip piece 19. The binding part 20 may be, for example, a ring-shaped elastic body (such as a rubber band).

[0065] <About the brightness sensor> The brightness sensor 21 is disposed at a position in the main body 10 where it can detect the brightness on the display DS side, and in this embodiment, it is disposed at a desired position on the upper end surface 11a side of the display device 11 covered by the wall 13 so as to be able to detect the brightness on the display DS side. Specifically, the brightness sensor 21 is disposed at a position corresponding to the through hole 13b formed in the wall 13, and is disposed so as to be able to receive light from the display DS side through the through hole 13b.

[0066] The brightness sensor 21 is a diode capable of detecting light intensity according to the brightness of the surroundings where the brightness sensor 21 is disposed, generating a current and a voltage, and outputting the brightness as a digital signal. The brightness sensor 21 corresponds to a "brightness detection means" capable of acquiring the light of the surroundings where the brightness sensor 21 is disposed and detecting the brightness, and is disposed so as to be capable of transmitting the brightness as a digital signal to a brightness control section (brightness control means) on the display device section 11 side (this is an example, and the present invention is not limited to this configuration). Note that the shapes of the brightness sensor 21 in this embodiment and the brightness sensors 31, 41, 51 (see Figs. 7 to 9) in other examples described later are examples, and other desired shapes may be used.

[0067] <How to attach a digital mirror to a rearview mirror> The digital mirror 1 is attached to the rearview mirror M in a manner as shown in Fig. 5, for example. In Fig. 5, first, the mirror body part Ma of the rearview mirror M is placed between the upper gripping piece 18 and the lower gripping piece 19 of the digital mirror 1. At this time, it is preferable that the mirror body part Ma is positioned so that the mirror surface of the mirror body part Ma abuts against each of the upper buffer part 15 and the lower buffer part 17 of the digital mirror 1. Also, at this time, it is preferable that the positions of the mirror body part Ma and the digital mirror 1 coincide in the width direction D2.

[0068] In this state, if the upper gripping piece 18 and the lower gripping piece 19 cooperate to clamp (hold) the mirror main body Ma so that the digital mirror 1 does not fall off from the rearview mirror M, then attachment of the digital mirror 1 to the rearview mirror M may be complete. For example, if the vertical distance between the upper gripping piece 18 and the lower gripping piece 19 corresponds appropriately to the vertical width of the mirror main body Ma, and the frictional forces generated between the upper gripping piece 18 and the mirror main body Ma, and between the lower gripping piece 19 and the mirror main body Ma, respectively, are sufficiently large, then a separate operation may not be required to attach the digital mirror 1 to the rearview mirror M. That is, in this case, the digital mirror 1 does not need to be provided with the binding part 20.

[0069] On the other hand, if the digital mirror 1 may fall off from the rearview mirror M even in this state, attachment of the digital mirror 1 to the rearview mirror M may be completed by performing a separate operation as described below. For example, a binding part 20 may be provided between the vicinity of the tip 18b of the upper gripping piece 18 and the vicinity of the tip 19b of the lower gripping piece 19, thereby generating a biasing force that brings the upper gripping piece 18 and the lower gripping piece 19 closer to each other. In this way, the upper gripping piece 18 and the lower gripping piece 19 cooperate to sandwich (hold) the mirror main body part Ma, making it difficult for the digital mirror 1 to fall off from the rearview mirror M. That is, in this case, the digital mirror 1 is provided with the binding part 20.

[0070] <About placing the digital mirror on the dashboard> The digital mirror 1 can be placed on the dashboard DB, for example, in a manner as shown in Fig. 6. In Fig. 6, the digital mirror 1 is placed so that the display DS side faces up (looks up) toward the occupant at a desired angle so that the occupant sitting in the driver's seat can easily view the display DS. The dashboard DB may be provided with a digital mirror placement section 22 on which the digital mirror 1 can be placed at the desired angle.

[0071] <Operation of this embodiment> According to this embodiment having the above configuration, the brightness sensor (brightness detection means) 21 is disposed at a position on the main body 10 where it can detect the brightness from the display DS side, making it possible to detect the brightness on the display DS side.

[0072] More specifically, according to this embodiment, at least the brightness sensor 21 is arranged at a desired location on the upper end surface 11a of the display device unit 11 covered by the wall portion 13 so as to be able to detect the brightness on the display DS side, thereby making it possible to detect the brightness on the display DS side. Furthermore, according to this embodiment, the brightness sensor 21 is disposed at a desired location on the upper end surface 11a side of the display device unit 11 covered by the wall portion 13, so that when adjusting the angle of the mirror main body portion Ma of the rearview mirror M, the brightness sensor 21 does not interfere with the ceiling inside the vehicle cabin.

[0073] Furthermore, according to this embodiment, the wall portion 13 is formed so that the brightness sensor 21 can receive light from the display DS side, making it possible to detect the brightness on the display DS side.

[0074] Furthermore, according to this embodiment, the digital mirror 1 is configured so as to be able to be placed in a desired location within the vehicle cabin, so for example, the digital mirror 1 can be placed on the dashboard DB within the vehicle cabin.

[0075] Furthermore, according to this embodiment, when the desired location in the vehicle cabin is on the dashboard DB, the digital mirror 1 is placed so that it faces upward toward the occupant sitting in the driver's seat at a desired angle that enables the occupant to view the display DS. Therefore, even when the digital mirror 1 is placed on the dashboard DB, the occupant can easily view the captured image displayed on the display 1.

[0076] <Effects Obtained by the Present Embodiment> According to the present embodiment, it is possible to detect the brightness from the display DS side, thereby enabling more accurate brightness adjustment of the captured image.

[0077] In addition to the first embodiment described above, the digital mirror according to the present invention may also adopt the second embodiment described below. Hereinafter, the second embodiment of the digital mirror according to the present invention will be described with reference to FIG.

[0078] 7 is a perspective view showing a state in which a digital mirror according to a second embodiment of the present invention is viewed from the front side. Note that the same components as those in the first embodiment are given the same reference numerals and detailed explanations are omitted.

[0079] <About Digital Mirror> Digital mirror 30 in this embodiment shown in Fig. 7 is the same as that in the first embodiment in configuration and structure, except that it has brightness sensor 31 instead of brightness sensor 21 in the first embodiment (see Figs. 2 and 3, etc.). Moreover, brightness sensor 31 differs from brightness sensor 21 in the first embodiment only in its shape, and like brightness sensor 21 in the first embodiment, it corresponds to a "brightness detection means" that can obtain light around where brightness sensor 31 is disposed and detect the brightness.

[0080] <Location of the brightness sensor> The brightness sensor 31 is disposed at a position on the main body 10 where it can detect the brightness on the display DS side, and in this embodiment, the brightness sensor 31 is disposed at a desired position on the upper end 10c side of the main body 10 so as to be able to detect the brightness on the display DS side. Specifically, the brightness sensor 31 is disposed on the upper surface of the base 12 so as to be able to receive light from the display DS side. The above-mentioned position of the brightness sensor 31 is one example, and it may also be disposed, for example, at the upper end of the wall 13 (i.e., the position corresponding to the upper end 10c in FIG. 7) so as to be able to detect the brightness on the display DS side.

[0081] The shape of the brightness sensor 31 in this embodiment is just an example, and the brightness sensor 31 may have any other desired shape. However, with the digital mirror 30 attached to the rearview mirror M (see FIG. 5), the brightness sensor 31 is formed in a shape and height that does not interfere with the ceiling inside the vehicle compartment when the angle of the mirror main body Ma is adjusted.

[0082] <Operation of this embodiment> According to this embodiment having the above configuration, the brightness sensor 31 is disposed at a desired location on the upper end 10c side of the main body 10 so as to be able to detect the brightness on the display DS side, making it possible to detect the brightness on the display DS side. Furthermore, according to this embodiment, with the digital mirror 30 attached to the rearview mirror M, when adjusting the angle of the mirror main body part Ma, the brightness sensor 31 is formed with a shape and height that does not interfere with the ceiling of the vehicle interior. This makes it possible to adjust the angle of the mirror main body part Ma without the brightness sensor 31 interfering with the ceiling of the vehicle interior.

[0083] <Effects Obtained by the Present Embodiment> According to the present embodiment, the same effects as those of the first embodiment are achieved.

[0084] In addition to the above first and second embodiments, the digital mirror according to the present invention may also adopt the following third embodiment. Hereinafter, the third embodiment of the digital mirror according to the present invention will be described with reference to FIG.

Brightness sensor 41 differs from brightness sensor 21 in the first embodiment only in its shape, and like brightness sensor 21 in the first embodiment, it corresponds to a "brightness detection means" that can obtain light around where brightness sensor 41 is disposed and detect the brightness.

[0087] <Location of the brightness sensor> The brightness sensor 41 is disposed at a position on the main body 10 where it can detect the brightness on the display DS side, and in this embodiment, the brightness sensor 41 is disposed at a desired position on the bottom end 10d side of the main body 10 so as to be able to detect the brightness on the display DS side. Specifically, the brightness sensor 41 is disposed at the bottom end 10d of the main body 10 so as to be able to receive light from the display DS side.

[0088] Note that the shape of the brightness sensor 41 in this embodiment is just an example, and the brightness sensor 41 may have any other desired shape; however, the brightness sensor 41 should be formed with a shape and height that does not detract from the appearance when the digital mirror 40 is attached to the rearview mirror M (see FIG. 5) and does not interfere with other parts in the vehicle cabin.

[0089] <Operation of this embodiment> According to this embodiment having the above configuration, the brightness sensor 41 is disposed at a desired location on the lower end 10d of the main body 10 so as to be able to detect the brightness on the display DS side, making it possible to detect the brightness on the display DS side. Furthermore, according to this embodiment, the digital mirror 40 is formed with a shape and height that does not detract from the appearance when attached to the rearview mirror M and does not interfere with other parts in the vehicle cabin, so the placement of the brightness sensor 41 does not detract from the appearance and does not interfere with other parts in the vehicle cabin.

[0091] In addition to the above first to third embodiments, the digital mirror according to the present invention may also adopt the following fourth embodiment. Hereinafter, the fourth embodiment of the digital mirror according to the present invention will be described with reference to FIG.

[0092] 9 is a perspective view showing a state in which a digital mirror according to a fourth embodiment of the present invention is viewed from the front side. Note that the same components as those in the first embodiment are given the same reference numerals and detailed explanations are omitted.

[0093] <About Digital Mirror> Digital mirror 50 in this embodiment shown in Fig. 9 is the same as that in the first embodiment in configuration and structure, except that it has brightness sensor 51 instead of brightness sensor 21 in the first embodiment (see Figs. 2 and 3, etc.). Brightness sensor 51 differs from brightness sensor 21 in the first embodiment only in its shape, and like brightness sensor 21 in the first embodiment, it corresponds to a "brightness detection means" that can obtain light around where brightness sensor 51 is disposed and detect the brightness.

[0094] <Location of the brightness sensor> The brightness sensor 51 is disposed at a position in the main body 10 where it can detect the brightness on the display DS side, and in this embodiment, the brightness sensor 51 is disposed at a desired position on one side end of the main body 10 so as to be able to detect the brightness on the display DS side. Specifically, the brightness sensor 51 is disposed at the other end 11c of the display device 11 in the width direction D2, and is disposed so as to be able to receive light from the display DS side.

[0095] The shape of the brightness sensor 51 in this embodiment is just an example, and the brightness sensor 51 may have any other desired shape. However, the brightness sensor 51 is formed with a shape and height that does not interfere with a sun visor (not shown) provided on the ceiling inside the vehicle compartment when the sun visor is lowered when the digital mirror 50 is attached to the rearview mirror M (see FIG. 5).

[0096] <Operation of this embodiment> According to this embodiment having the above-mentioned configuration, the brightness sensor 51 is arranged at a desired location at one of a pair of side ends of the main body unit 10 (i.e., the other end 11c in the width direction D2 of the display device unit 11) so as to be able to detect the brightness on the display DS side, thereby making it possible to detect the brightness on the display DS side. Furthermore, according to this embodiment, when the digital mirror 50 is attached to the rearview mirror M, the sun visor is formed with a shape and height that does not interfere with the brightness sensor 51 when the sun visor is lowered, so that the sun visor can be lowered without interfering with the brightness sensor 51.

[0097] <Effects Obtained by the Present Embodiment> According to the present embodiment, the same effects as those of the first embodiment are achieved.

[0098] In addition to the above first to fourth embodiments, the digital mirror according to the present invention may also adopt the following fifth embodiment. Hereinafter, the fifth embodiment of the digital mirror according to the present invention will be described with reference to FIG.

[0099] 10 is a perspective view showing a digital mirror according to a fifth embodiment of the present invention as viewed from the front side. Note that the same components as those in the first embodiment are given the same reference numerals and detailed description will be omitted.

[0101] <Location of the brightness sensor> The brightness sensor 21 is disposed at a position on the main body 10 where it can detect the brightness on the display DS side, and in this embodiment, the brightness sensor 21 is disposed at a desired position on the surface 10a side of the wall 13 so as to be able to detect the brightness on the display DS side. Specifically, the brightness sensor 21 is disposed on the surface 10a of the wall 13 (i.e., the outer surface on the display DS side of the wall 13) and is disposed so as to be able to receive light from the display DS side.

[0102] Note that the shape of the brightness sensor 21 in this embodiment is just an example, and the brightness sensor 21 may have any other desired shape; however, the brightness sensor 21 should be formed with a shape and height that does not detract from the appearance when the digital mirror 60 is attached to the rearview mirror M (see FIG. 5) and does not interfere with other parts in the vehicle cabin.

[0103] <Operation of this embodiment> According to this embodiment having the above-mentioned configuration, the brightness sensor 21 is arranged at a desired location on the surface 10a side of the wall portion 13 of the main body portion 10 so as to be able to detect the brightness on the display DS side, making it possible to detect the brightness on the display DS side. Furthermore, according to this embodiment, the digital mirror 60 is formed with a shape and height that does not detract from the appearance when attached to the rearview mirror M and does not interfere with other parts in the vehicle cabin, so the placement of the brightness sensor 21 does not detract from the appearance and does not interfere with other parts in the vehicle cabin.

[0104] <Effects Obtained by the Present Embodiment> According to the present embodiment, the same effects as those of the first embodiment are obtained.

[0105] In addition to the above first to fifth embodiments, the digital mirror according to the present invention may also adopt the following sixth embodiment. Hereinafter, the sixth embodiment of the digital mirror according to the present invention will be described with reference to Figs. 11 and 12.

[0106] Fig. 11 is a perspective view showing a digital mirror according to a sixth embodiment of the present invention as viewed from the front side, and Fig. 12 is a perspective view showing a digital mirror according to the sixth embodiment of the present invention as viewed from the back side. Note that the same components as those in the first embodiment are given the same reference numerals and detailed explanations will be omitted.

[0107] <About Digital Mirror> 11 and 12, digital mirror 70 of this embodiment is the same as that of the first embodiment in configuration and structure, except that it has wall 71 instead of wall 13 (see FIGS. 2 and 3, etc.) in the first embodiment, and has brightness sensor 72 instead of brightness sensor 21 (see FIGS. 2 and 3, etc.) in the first embodiment. Similarly to brightness sensor 21 in the first embodiment, brightness sensor 72 corresponds to a "brightness detection means" capable of obtaining light in the vicinity where brightness sensor 72 is disposed and detecting brightness.

[0108] <About the walls> The wall portion 71 is provided in a range from one end 11b to the other end 11c in the width direction D2 of the display device unit 11. The wall portion 71 is provided over the entire display device unit 11 in the width direction D2, and is formed to have a constant height and thickness. The wall portion 71 is configured to be provided only in a range from one end 11b to the other end 11c in the width direction D2 of the display device unit 11, and is configured to omit a wall portion formed along the side surface of the display device unit 11, such as the wall portion 13 in the first embodiment. Note that the wall portion 71 may be provided with a wall portion formed along the side surface of the display device unit 11, similar to the wall portion 13 in the first embodiment.

[0109] The wall 71 has a storage section 71b formed so that the brightness sensor 72 can be stored and disposed therein, and a through hole section 71c formed at a position where the brightness sensor 72 stored and disposed in the storage section 71b can receive light from the display DS side.

The reference numeral 71a shown in FIG. 11 denotes a "display" similar to the display 13a in the first embodiment.

[0110] <Location of the brightness sensor> The brightness sensor 72 is disposed at a location on the main body 10 where it can detect the brightness on the display DS side. In this embodiment, the brightness sensor 72 is stored and disposed at a position corresponding to the through hole portion 71c in the storage portion 71b, and is disposed so as to be able to receive light from the display DS side through the through hole portion 71c.

[0111] <Operation of this embodiment> According to this embodiment having the above configuration, the brightness sensor (brightness detection means) 72 is stored in the storage section 71b of the wall section 71, and the wall section 71 is formed so that the brightness sensor 72 can detect the brightness on the display DS side, making it even easier to detect the brightness on the display DS side. Furthermore, according to this embodiment, since the brightness sensor 72 is stored in the storage section 71b of the wall section 71, there is no need to arrange the brightness sensor 72 on the outside of the digital mirror 70. Therefore, the appearance of the digital mirror 70 is not adversely affected even if the brightness sensor 72 is provided, and the aesthetics of the digital mirror 70 can be improved.

[0112] <Effects Obtained by the Present Embodiment> According to this embodiment, the same effects as those of the first embodiment are achieved.
