<Embodiment 1>
FIG. 1 shows the awning device 1 of the first embodiment in a state in which the awning device 1 is arranged in a passenger compartment of an automobile C and is positioned at a use position. In addition, above the passenger seat of the automobile C, the shade member 20 that can form the second shade device is shown in a state of not being used. 2 shows the awning member 2 and the display device 3 of the awning device 1, and FIG. 3 shows a cross-sectional view taken along line III-III of FIG. Further, in FIGS. 4A and 4B, an imaging region 41 imaged by the imaging device 4 of the sunshade device 1 is schematically shown.

As shown in FIGS. 1 to 4B, the awning device 1 of the present embodiment includes a plate-shaped awning member 2 and an operator of the awning member 2, that is, a driver M in the present embodiment, when the awning member 2 is used. The front surface 2a is provided with the display device 3 arranged with the display unit 3a facing the driver M. The sunshade device 1 further includes an image pickup device 4 that picks up an image of a region facing the surface 2a opposite to the surface 2a of the sunshade member 2 and generates image pickup data. In the following description, the “front surface 2a” of the shade member 2 is also referred to as the “first surface 2a” of the shade member 2. The opposite surface 2b of the front surface 2a is also referred to as the "second surface 2b" of the shade member 2. The awning device 1 further generates a display image data to be displayed on the display unit 3a of the display device 3 when the awning member 2 is used, based on the imaging data generated by the imaging device 4 (FIG. 10). See). Although not shown, the image pickup device 4 and the data processing circuit 5 are connected so as to be able to send and receive data in a wired or wireless manner. Further, although the image pickup device 4 is depicted beside the shade member 2 in FIG. 1 for easy understanding, preferably, as shown in FIG. 4A, the driver M, the shade member 2, and the image pickup device 4 are arranged. The vehicles C are arranged at positions substantially linearly arranged in the front-rear direction.

In the following description, "use" of the shade member 2 means that at least one of the shades that can irradiate the area where the first surface 2a faces by positioning the shade member 2 at a position where the second surface 2b is illuminated by the sunlight. This means that the part is blocked by the shade member 2. The “use state” of the shade member 2 is a state where the shade member 2 is “used”, and the “use position” of the shade member 2 is a position where the shade member 2 is in the “use state”.

In the example shown in FIG. 1, the awning member 2 is attached to the ceiling portion of the interior of the vehicle C using a rod-shaped attachment member F that is bent in an L shape. As shown in FIG. 1, on the display unit 3a of the display device 3, an image of a front area in which the second surface 2b (see FIG. 3) of the shade member 2 faces, that is, the front of the automobile C in the example of FIG. An image of the scene outside the car through the glass is displayed. The display device 3 displays a traffic signal S1, a regulation sign S2 indicating “progressing outside the designated direction”, a guidance sign S3 indicating a main point and the like, and an auxiliary sign S4 indicating a regulation target time of the regulation sign S2. There is. In Japan, as road signs, such regulatory signs and guide signs, as well as main signs including instruction signs indicating specific permits and orders and warning signs calling attention, and auxiliary signs are installed. According to the awning device 1 of the present embodiment, a scene hidden by the awning member 2 is displayed on the display device 3, so that the driver M or the like can overlook these road signs and traffic lights even under backlight. Can be confirmed without.

The traffic signal S1 and the regulation sign S2 displayed on the display device 3 in FIG. 1 originally exist in the position where the driver M of the car C should be in the visual field in the positional relationship between the car C and the traffic signal S1 in FIG. doing. However, the area in which the traffic light S1 and the like are present is covered by the shade member 2 which is positioned at the use position so as to block the sunlight. However, in the present embodiment, the area of the shade member 2 facing the second surface 2b can be imaged by the imaging device 4. Then, based on the imaging data generated by the imaging device 4, the display image data to be displayed on the display device 3 is generated by the data processing circuit 5. As a result, the scene to be seen in the area covered by the shade member 2 is displayed as an image on the display device 3 provided on the surface 2a (see FIG. 3) of the shade member 2 facing the driver M. Therefore, as described above, the driver M can clearly confirm even under the backlight, for example, even the characters written on the guide sign or the auxiliary sign.

That is, as shown in FIGS. 4A and 4B, the image pickup device 4 is arranged in the automobile C so as to pick up an image of the image pickup region 41 including the blind spot portion B in the field of view of the driver M that is blocked by the shade member 2. .. The area including the blind spot B is imaged by the imaging device 4 arranged in this way, and imaging data is generated. Display image data based on the imaged data is generated by the data processing circuit 5 (see FIG. 10) and sent to the display device 3. As a result, an image of a scene including a region that can be the blind spot B can be displayed on the display device 3 (see FIG. 1) toward the driver M. The driver M can visually recognize the scene of the portion hidden by the shade member 2 through the display device 3. Therefore, it is possible to reduce the oversight of the traffic signal, the road sign, and the like by the driver M under the sunlight where the shade member 2 is used. It is considered that the awning device 1 of the present embodiment can contribute to ensuring traffic safety.

The display device similar to the display device 3 may be provided on the sunshade member 20 provided above and in front of the passenger seat in the example shown in FIG. That is, a second shade device including the shade member 20 and a display device arranged on the surface of the shade member 20 facing the operator (for example, a passenger sitting in the passenger seat) of the shade member 20 may be configured. Then, the display of the second awning device may also display the scene of the area of the awning member 20 facing the surface opposite to the surface on which the display device is arranged. In that case, the 2nd imaging device for the 2nd shade device may be provided, and the component similar to the component of the shade device 1 may be provided in the 2nd shade device. Therefore, the second awning device may have the same function as the awning device 1 described in more detail below.

In the present embodiment, the imaging device 4 is formed separately from the shade member 2 and is arranged inside the automobile C. As shown in FIG. 4A, the image pickup device 4 preferably has the driver M, the awning member 2, and the image pickup device 4 on a substantially straight line in the front-rear direction of the car C near the upper edge of the windshield of the car C. It will be placed in a line. Further, as shown in FIG. 4B, the imaging device 4 includes a central portion of the windshield of the automobile C in the left-right direction (vehicle width direction of the automobile C), for example, a rear surface of the rearview mirror (rear view mirror) RM (front of the automobile C). May be disposed on the surface facing to. As shown in FIGS. 4A and 4B, the imaging device 4 is arranged such that the blind spot portion B is entirely within the imaging region 41, for example, at a position ahead of the front end C1 of the automobile C at a distance. For example, a camera provided with a lens having an angle of view capable of providing such an imaging region 41 is used as the imaging device 4. Alternatively, the imaging device 4 is arranged at a position and an angle suitable for obtaining such an imaging region 41. As shown in FIG. 4A, when the shade member 2 and the image pickup device 4 are arranged so that the driver M, the shade member 2, and the image pickup device 4 are aligned on a substantially straight line, the image pickup including the lens with a small angle of view is performed. Even with the device 4, it becomes easy to fit the blind spot B in the imaging area 41.

The imaging device 4 is not limited to the positions shown in FIGS. 4A and 4B, and may be arranged at any position where the appropriate imaging region 41 can be obtained. For example, the imaging device 4 may be arranged near the left and right edges of the windshield of the automobile C or on a dashboard (not shown). It is preferable that at least a portion of the windshield facing the image pickup device 4 facing the outside of the vehicle is coated with an antifouling coating using a photocatalytic effect such as titanium oxide. Further, the imaging device 4 may be arranged on the second surface 2b of the shade member 2. However, as will be described later, since the shade member 2 can be used at any position (angle), the imaging device 4 is supported by a different object from the shade member 2 in terms of ensuring a stable imaging area 41. It is preferably arranged as much as possible.

The image pickup device 4 is not particularly limited as long as it can pick up a scene of a desired image pickup area and can generate image pickup data in a format that can be processed by the data processing circuit 5. For example, the image pickup device 4 is exemplified by a digital camera having a CCD image sensor or a CMOS image sensor. Light energy based on the scene in the imaging area is converted into electrical signals for each micro area by light receiving elements arranged in a matrix inside a CCD image sensor or the like, and imaging data based on those electrical signals is generated. .. Preferably, a camera having an image sensor capable of color photographing is used as the image pickup device 4.

In FIG. 4A, the imaging device 4 is enlarged and schematically shown in a circle Z indicated by a dashed line. The imaging device 4 of the awning device 1 of the present embodiment includes a lens 4b having a surface on which a coating layer 4a that reduces reflection of light by adjusting the refractive index is formed. The image pickup device 4 picks up an image of a scene in a region facing the second surface 2b, which is illuminated by sunlight when the shade member 2 is used. Therefore, the image pickup device 4 is required to shoot under the backlight. Therefore, the lens 4b of the imaging device 4 is provided with the coating layer 4a. The coating layer 4a can suppress the occurrence of flares and ghosts that are likely to occur in shooting under backlight. The coating layer 4a can be formed by forming a large number of nano-sized wedge-shaped structures on the surface of the lens 4b, or by forming a layer of nano-sized fine particles on the surface of the lens 4b. The image pickup device 4 does not necessarily have to include the lens having the coating layer 4a.

Again referring to FIGS. 2 and 3, the shade member 2 and the display device 3 will be described in more detail. The awning member 2 is formed in a plate shape, and has a substantially rectangular shape as a whole on the first surface 2a and the second surface 2b. An insertion hole 2c for engaging with the rod-shaped mounting member F is provided in the vicinity of one edge 2d1 of the two edges 2d1 and 2d2 that are substantially parallel to the longitudinal direction of the shade member 2. It is provided along with. The awning member 2 is attached to the automobile C via the attachment member F so that the edge 2d1 is on the upper side when the awning member 2 is used.

In addition, in the present embodiment, the shade member 2 has curved surface portions 2e1 and 2e2 near the two end edges 2d1 and 2d2, respectively. That is, the awning member 2 has curved surface portions 2e1 and 2e2 at an edge portion facing upward and an edge portion facing downward when the awning member 2 is used. The first surface 2a of the awning member 2 is a curved surface that is curved in a convex shape toward the end edges 2d1 and 2d2 in the curved surface portions 2e1 and 2e2. The radius of curvature (R1) of the curved surface portions 2e1 and 2e2 is preferably 5 mm or more and 20 mm or less. Further, instead of only the edge being curved, as described later, the shade member 2 may have a curved surface as a whole on the first surface 2a (see FIG. 5). In addition, the awning member 2 does not necessarily need to have the curved surface portions 2e1 and 2e2, and also has the curved surface portion only at one of the edge portions that are directed upward or downward when the awning member 2 is used. May be The shade member 2 is formed using, for example, a synthetic resin such as urethane. However, the material of the awning member 2 may be any material that can block the transmission of light even a little, and the material of the awning member 2 is not limited to the synthetic resin. Further, the shape of the shade member 2 is not limited to the rectangular shape as a whole, and the shade member 2 may have any shape.

The second surface 2b of the shade member 2 is exposed to the sunlight when the shade member 2 is used. The display device 3 is arranged on the first surface 2 a of the shade member 2. In an electronic device used as the display device 3, particularly in an organic EL display panel or the like suitable as the display device 3 of the awning device 1 of the present embodiment as described later, the brightness decreases as the temperature rises, and In some cases, the luminance decreases with time as the temperature rises. Therefore, it is preferable that the second surface 2b of the shade member 2 be provided with a measure for reflecting infrared rays included in the sunlight. When the shade member 2 is formed of synthetic resin or the like, the shade member 2 is rarely used in a state where the material is exposed, and the surface of the shade member 2 is decorated. In particular, in the present embodiment, it is preferable that at least the second surface 2b, which is the surface of the shade member 2 on which the display device 3 is not arranged, be decorated. From these viewpoints, it is preferable that at least the second surface 2b of the shade member 2 is provided with an infrared reflecting member 21 having a performance of reflecting infrared rays, as shown in FIG. Further, it is more preferable that the infrared reflecting member 21 contains a material having a decorative property such as natural or synthetic leather, or cloth made of pile fabric such as moquette.

The infrared reflecting member 21 is exemplified by a coating film formed of an infrared reflecting paint containing a pigment having a high reflectance for infrared rays. Further, such an infrared-reflecting coating material may further include hollow beads made of titanium oxide or ceramics, which have the property of absorbing infrared rays and the property of diffusely reflecting infrared rays. The infrared reflective member 21 may be provided by applying such an infrared reflective coating material to at least the second surface 2b of the shade member 2. Further, by applying such an infrared reflective coating material to a fabric made of natural or synthetic leather or pile fabric, an infrared reflective member 21 including a leather material or a fabric is formed, and the infrared reflective member 21 is used as an awning member. It may also be mounted on the surface of two. When the surface of the shade member 2 is decorated with a material containing cloth, beads such as ceramics may be kneaded into the cloth. Further, the fabric may be a fabric woven by a ceramic-woven yarn, and is a fabric woven by a yarn having a star-shaped or cross-shaped cross-sectional shape suitable for irregularly reflecting infrared rays. It may be.

The display device 3 displays an image based on the display image data generated by the data processing circuit 5 (see FIG. 10) on the display unit 3a. The display device 3 is not particularly limited as long as it has such a function and can be arranged on the surface 2a of the sunshade member 2, but the display device 3 is preferably an organic EL display which may have a thin shape. It is preferably a panel or a liquid crystal display panel. In the example shown in FIG. 2, the display device 3 is provided over the entire first surface 2a except for the portions near the two short sides of the shade member 2. In addition, almost the entire surface of the display device 3 exposed to the first surface 2a of the sunshade member 2 constitutes the display portion 3a.

In the present embodiment, the display device 3 is formed along the curved surfaces of the curved surface portions 2e1, 2e2 in each of the two curved surface portions 2e1, 2e2 of the shade member 2. The radius of curvature (R1) of each of the curved surface portions 2e1 and 2e2 is, for example, 10 mm. Since the display device 3 is formed along the curved surface portions 2e1 and 2e2 in this way, when the driver views the display device 3 from an oblique direction with respect to the first surface 2a of the shade member 2, the curved surface portions 2e1 and 2e2 are formed. Good visibility can be secured as compared with the case where the display device 3 is not formed on the curved surfaces 2e1 and 2e2. Different from the shape shown in FIG. 3, the first surface 2a of the shade member 2 may be a curved surface over the entire surface as shown in FIG. In this case, the radius of curvature (R2) of the first surface 2a is preferably 50 mm or more and 250 mm or less, and for example, R2=150 mm. Thus, even on the first surface 2a which is a curved surface over the entire surface, when the driver M looks at the display device 3 from an oblique direction, relatively good visibility is secured. The advantage that the shade member 2 has the curved surface portion will be described in detail in the following description.

As shown in FIG. 6, the shade device 1 of the present embodiment may include a detector (first detector 6) that detects the position of the shade member 2. The 1st detector 6 detects the position of the shade member 2 at least in order to distinguish the use state and non-use state of the shade member 2. Further, the first detector 6 preferably detects the position of the shade member 2 by detecting the angle of the first surface 2a of the shade member 2 (for example, the angle with respect to the line of sight of the driver M).

In FIG. 6, an angle sensor 6b is shown as an example of the first detector 6. In the example of FIG. 6, the angle sensor 6b is a rotation angle detection sensor using a rotary potentiometer. The angle sensor 6b of FIG. 6 has a movable portion 6b1 which rotates around the mounting member F as an axis together with the shade member 2 and a fixed portion 6b2 which is fixed to the mounting member F, and has an insertion hole 2c into which the mounting member F is inserted. It is arranged around. The angle sensor 6b detects the difference in position in the circumferential direction about the mounting member F as an axis between the fixed portion 6b2 and the movable portion 6b1 that rotates together with the sunshade member 2, thereby detecting the angle of the sunshade member 2. That is, the position in the rotation direction is detected.

In the example shown in FIGS. 7A and 7B, the shade member 2 includes a first detector in the vicinity of an edge 2d1 opposite to the edge 2d1 in which the insertion hole 2c (see FIG. 3) is provided in the vicinity thereof. A magnetic sensor 6 a is provided as 6. 7A and 7B show examples of the usage state of the shade member 2 as a view from the side of the driver M. The awning member 2 is connected to the mounting member F in a rotatable manner. The awning member 2 is rotated around the mounting member F so as to be positioned from the unused position P0, which is the unused position, to the used position P1 in FIG. 7A, the used position P2 in FIG. 7B, and the like.

The magnet 61 is arranged at a position close to the magnetic sensor 6a when the shade member 2 is at the non-use position P0. Further, when the shade member 2 is located at the position farthest from the non-use position P0 about the mounting member F (the use position P2 in FIG. 7B in the example of FIGS. 7A and 7B), it comes close to the magnetic sensor 6a. The magnet 62 is arranged at the position. The magnets 61 and 62 may be arranged, for example, on the surface of the interior of the ceiling or on the back side thereof, or on the surface of the pillar C2 and inside.

The magnets 61 and 62 are arranged, for example, with the same magnetic pole (N pole or S pole) facing the magnetic sensor 6a. The magnetic sensor 6a moves in the magnetic field created by the magnet 61 and the magnet 62 as the sunshade member 2 rotates. The magnetic sensor 6a detects the direction and strength of the magnetic field at its own position, and electrically outputs the detection result, for example. By using the magnetic sensor 6a and the magnets 61 and 62, it is possible to reliably detect whether the shade member 2 is in the non-use position P0 or a predetermined use position, for example, the use position P2. The magnetic sensor 6a can be configured by, for example, a Hall element, or simply a magnetic coil or the like. The 1st detector 6 should just be able to detect the position of the shade member 2, and is not limited to the illustrated example. For example, a magnet may be arranged at the position of the magnetic sensor 6a in FIGS. 7A and 7B, and a magnetic sensor may be provided as the first detector 6 at each of the magnets 61 and 62. Further, only one of the magnets 61 and 62 may be arranged.

When the first detector 6 is provided, the shade device 1 is preferably provided with a control circuit 7 (see FIG. 10) connected to the first detector 6. The control circuit 7 determines whether or not the shade member 2 is in the use position based on at least the detection result of the first detector 6. Then, the on/off state of the display device 3 is controlled based on the determination. For example, when the detection result of the first detector 6 indicates that the shade member 2 is located farther from the non-use position P0 than the predetermined position, the control circuit 7 indicates that the shade member 2 is in the use position. To judge. Then, when the display device 3 is in the off state at that time, the control circuit 7 controls the display device 3 to be in the on state and causes the display unit 3a to display an image. When the detection result of the first detector 6 indicates that the shade member 2 is closer to the non-use position P0 than the predetermined position, the control circuit 7 indicates that the shade member 2 is in the non-use position. to decide. Then, when the display device 3 is in the ON state at that time, the control circuit 7 may control the display device 3 to be in the OFF state and stop displaying the image on the display unit 3a. By providing the awning device 1 with such a configuration, the driver M can display an image on the display device 3 or stop the display only by operating the awning member 2. The first detector 6 is not limited to the magnetic sensor 6a and the angle sensor 6b, and may be any detector capable of detecting an event that changes based on the position (angle) of the shade member 2, such as a gravity sensor. Good. The first detector 6 may not be provided. That is, the on/off control of the display device 3 may be performed by the operator of the shade member 2.

The advantages of having the curved portion of the shade member 2 are described below with reference to FIGS. 7A and 7B. When the shade member 2 is in the use position P1, the driver M looks at the display device 3 from an oblique direction with respect to the first surface 2a of the shade member 2. In that case, the shade member 2 does not have the curved surface portion 2e2, and as a result, if there is no portion along the curved surface of the curved surface portion 2e2 in the display device 3, the driver M is in the display device 3 with respect to the driver M. You can only see the part that is facing diagonally. However, the shade member 2 of the present embodiment has the curved surface portion 2e2, and the display device 3 is formed along the curved surface of the curved surface portion 2e2. Therefore, the driver M can see the image displayed in the area including the portion perpendicular to the line of sight of the driver M even in the vicinity of the edge 2d2. The visibility of the driver M with respect to the display device 3 is higher than in the case where the curved surface portion 2e2 is not provided.

Even when the shade member 2 is in the use position P2, the driver M will see the display device 3 from an oblique direction with respect to the normal line of the first surface 2a of the shade member 2. In the present embodiment, the awning member 2 has the curved surface portion 2e1 and the display device 3 is formed along the curved surface of the curved surface portion 2e1. Therefore, the driver M can drive the driver M even near the edge 2d1. It is possible to see the image displayed in the area including the portion perpendicular to the line of sight of. The visibility of the driver M with respect to the display device 3 is higher than that when the curved surface portion 2e1 is not provided.

In this way, the shade member 2 has the curved surface portions 2e1 and 2e2, and the display device 3 is formed along the curved surfaces of the curved surface portions 2e1 and 2e2, whereby good visibility of the driver M is secured. .. Specifically, it is considered that the curved surface portion (curved surface portion 2e1 or curved surface portion 2e2) of the end surface closer to the driver M among the end edges 2d1 and 2d2 mainly contributes to ensuring the visibility of the driver M. .. The driver M usually tends to operate the shade member 2 randomly. Therefore, the shade member 2 is used at an arbitrary position where the first surface 2a is inclined with respect to the driver M. The awning member 2 preferably has a curved surface portion such as a curved surface portion 2e1 and a curved surface portion 2e2 at least in the vicinity of either the edge 2d1 or the edge 2d2. The effect of improving the visibility as described above can be obtained. It is further preferable that the shade member 2 has curved surface portions such as the curved surface portion 2e1 and the curved surface portion 2e2 near the end edge 2d1 and the end edge 2d2, respectively. Further, the display device 3 may be a liquid crystal display panel as described above, but an organic EL display panel capable of being softer and flexible than the liquid crystal display panel is preferable as the display device 3. An organic EL display panel formed using a flexible film having a surface on which organic materials are laminated is particularly preferable as the display device 3.

The sunshade member 2 may be attached to the automobile C so as to block the sunlight that is inserted through the window of the door of the driver's seat. That is, as shown in FIG. 8, it may be mounted on the automobile C via a mounting member F rotatably mounted on the ceiling of the vehicle compartment. In order to correspond to the usage pattern as shown in FIG. 8, the shade device 1 may include a further detector (third detector 9) for detecting the position of the shade member 2. The third detector 9 detects the position of the shade member 2 in a direction different from the direction in which the position of the shade member 2 can be detected by the first detector 6 (see FIG. 6). In FIG. 8, a magnetic sensor 9a is illustrated as the third detector 9.

The magnetic sensor 9a is arranged in the shade member 2 in the vicinity of the radial end of the mounting member F in rotation. The magnet 91 is arranged at a position close to the magnetic sensor 9a when the shade member 2 is moved by the rotation of the mounting member F so as to cover a part of the window of the door of the driver's seat. The magnet 91 may be arranged, for example, on the surface of the interior of the ceiling part or the upper part of the door frame or the back side thereof.

The magnetic sensor 9a functions similarly to the above-mentioned magnetic sensor 6a. That is, the magnetic sensor 9a detects the position of the mounting member F in the rotation direction of the sunshade member 2 based on the strength of the magnetic field generated by the magnet 91. Then, the control circuit 7 (see FIG. 10) determines whether the shade member 2 is used for the windshield or the window of the door based on the detection result of the third detector 9. For example, if the detection result of the third detector 9 indicates that the shade member 2 is closer to the window of the door than the predetermined position, the control circuit 7 causes the shade member 2 to move toward the window glass of the door. It is determined that it is being used. Then, when the display device 3 is in the ON state at that time, the control circuit 7 controls the display device 3 to be in the OFF state and stops displaying the image. In this case, the control circuit 7 may control the display device 3 to the off state based on only the detection result of the third detector 9 regardless of the detection result of the first detector 6 described above.

Further, the awning device 1 of the present embodiment is provided with a second display device 39 on the surface 2ab of the awning member 2 facing the operator (driver) in the use position as shown in FIG. The second image pickup device 42 may be provided for picking up an area facing the opposite surface of the front surface 2ab to generate image pickup data. When the third detector 9 detects that the sunshade member 2 rotates along the windshield about an axis different from the rotation axis (rotational axis of the mounting member F), the second The display device 39 may be controlled to be in the ON state, and the image based on the image pickup data generated by the second image pickup device 42 may be displayed on the display unit of the second display device 39. It is possible to allow the driver to visually recognize a scene of a blind spot portion that may occur at the use position of the shade member 2 shown in FIG. Also in this case, the control circuit 7 controls the second display device 39 to be in the on state, and controls the display device 3 arranged on the surface of the shade member 2 facing the window glass of the shade member 2 to be in the off state. May be.

The second display device 39 is exposed to the sunlight when the shade member 2 is used for the windshield. Therefore, it is preferable that an infrared reflection layer or an infrared absorption layer made of a transparent material is formed on the surface (display screen) of the second display device 39. With such a configuration, deterioration of the second display device 39 due to heat can be suppressed. The infrared reflective layer is formed using, for example, antimony-doped tin oxide (ATO) or tin-doped indium oxide (ITO). For example, the infrared reflective layer can be formed by applying a vehicle containing a nanoparticle dispersion of ATO or ITO to the surface of the second display device 39. The particle size of the nanoparticle dispersion is not particularly limited, but is preferably 20 nm or more and 50 nm or less. Further, the infrared absorption layer can be formed using, for example, a cesium tungsten oxide nanoparticle dispersion. Further, it is more preferable that the infrared reflecting layer and the infrared absorbing layer have an ultraviolet absorbing function. Even if the second display device 39 contains an organic material that is easily affected by ultraviolet rays, the deterioration of image quality can be prevented.

In this way, the control circuit 7 may control the on/off state of the display device 3 based on the detection result of the third detector 9 as well as the first detector 6. Display of unnecessary images directed to the outside of the automobile C can be prevented. It should be noted that the third detector 9 may be an angle sensor arranged at the engaging portion between the mounting member F and the ceiling portion, similar to that illustrated in FIG. 6 for the first detector 6. Further, only the third detector 9 may be provided without providing the first detector 6.

The awning device 1 of the present embodiment may further include a detector (second detector 8) that detects the position of the eyes of the driver M. The second detector 8 is, for example, as shown in FIG. 9, an analysis device that analyzes images captured by the eye detection cameras 8a and 8b and the eye detection cameras 8a and 8b, which are installed at two known positions, respectively. (Not shown). The eye detection cameras 8a and 8b include, for example, a far-infrared sensor, and generate temperature data of each part in the imaging region. The eyes of an ordinary person are characterized by a lower temperature than other parts of the face. An analysis device (not shown) specifies the position of the face of the driver M and the position of the eyes of the driver M in the images captured by the eye detection cameras 8a and 8b based on the temperature data generated by the eye detection cameras 8a and 8b. A general digital camera may be used as the eye detection cameras 8a and 8b, and the position of the eye may be specified by image recognition in an analysis device (not shown).

By specifying the position of the eyes of the driver M in the images captured by the eye detection cameras 8a and 8b, a straight line L1 connecting the two eye detection cameras 8a and 8b at known positions and the eye detection camera 8a. , 8b and the straight line connecting the eyes of the driver M, the angles θ1 and θ2 are specified. Then, based on the length of the straight line L1 and the angles θ1 and θ2, the position of the eyes of the driver M with respect to the eye detection cameras 8a and 8b is specified using trigonometry. Only one of the positions of both eyes of the driver M may be specified, or the positions of both eyes may be specified. When the positions of both eyes are specified, for example, the position of the midpoint of a line connecting both eyes is calculated, and the position of the midpoint is treated as the position of the eyes of the driver M. Further, when one of the eyes is preferentially used during driving (for example, when the driver M has damaged the other eye, or when he/she wants to visually recognize an image with his or her eyes), the awning of the present embodiment The device 1 preferably has an auxiliary unit for switching from the setting based on both eyes to the setting based on one eye and designating whether to use the right eye or the left eye. The information is used for data processing by the display target data selection circuit 53 described later. The method of using the detection result of the second detector 8 will be described later.

FIG. 10 is a block diagram showing main components of the awning device 1 of the present embodiment. The image pickup data generated by the image pickup device 4 is sent to the data processing circuit 5. The display image data generated by the data processing circuit 5 based on the captured image data is sent to the display device 3, and the image based on the display image data is displayed on the display unit 3a of the display device 3. The above-mentioned first detector 6 and third detector 9 are connected to the control circuit 7. The first detector 6 is connected to the data processing circuit 5 together with the above-mentioned second detector 8. Although the second display device 39 and the second imaging device 42 (both of which are shown in FIG. 8) are omitted in FIG. 10, the second display device 39 is similar to the display device 3 in that Connected to the processing circuit 5 and the control circuit 7, the second imaging device 42 may be connected to the data processing circuit 5 in the same manner as the imaging device 4.

The control circuit 7 is connected to the display device 3 to control the on/off state of the display device 3 based on the detection results of the first and/or third detectors 6 and 9. The control circuit 7 can be configured by, for example, a comparator or a combination of several gate elements. Further, the control circuit 7 may be configured by a microcomputer or a part of a gate array, or may be included in the data processing circuit 5. Note that FIG. 10 is only an example of the configuration of the awning device 1 according to the present embodiment, and the awning device 1 may not necessarily include all the components illustrated in FIG. 10, and is illustrated in FIG. 10. It may further include a non-constituent element. Further, the internal configuration of the data processing circuit 5 is not limited to that shown in FIG.

The data processing circuit 5 is a circuit block having a unique function, that is, a data generation circuit 50, an angle identification circuit 51, a data correction circuit 52, a display target data selection circuit 53, a memory circuit 54, a comparison circuit 55, and a display image. An enhancement circuit 56 is included. The display target data selection circuit 53 includes a memory circuit 53a. These circuit blocks may partially or wholly share the same circuit element. The data processing circuit 5 can be formed by an arbitrary signal processing semiconductor device such as a microcomputer, ASIC, or FPGA and its peripheral circuits. The microcomputer or the like operates according to software that defines a predetermined processing procedure. Each circuit block in the data processing circuit 5 may be individually formed by using a semiconductor integrated circuit device or an individual semiconductor element.

The data generation circuit 50 is a circuit block having a basic function of the data processing circuit 5, and based on the imaged data, a drive signal including information about the light emission intensity and the light emission timing of each pixel of the display device 3 as display image data. To generate. The data generation circuit 50 may be, for example, a so-called timing controller and its peripheral circuits that are used to generate a drive signal for an organic EL display panel or the like and operate according to software that defines a predetermined processing procedure.

The functions of the angle identification circuit 51 and the data correction circuit 52 will be described below with reference to FIGS. 11A, 11B, 12A and 12B. The angle identifying circuit 51, based on the detection result of the first detector 6 and the detection result of the second detector 8, the surface (first surface) 2a of the shade member 2 with respect to the line of sight of the driver M directed toward the shade member 2. The angle θA is identified. As described above, the first detector 6 can detect the position of the shade member 2 in the rotation direction. Therefore, the positional relationship between the shade member 2 and the two eye detection cameras 8a and 8b at known positions can also be specified from the detection result of the first detector 6. In addition, the second detector 8 can detect the position of the eyes of the driver M with respect to the eye detection cameras 8a and 8b (see FIG. 9). Therefore, the position of the eyes of the driver M with respect to the shade member 2 is also specified, and as a result, the direction of the line of sight I of the driver M looking at the shade member 2 can be specified. That is, based on the detection result of the first detector 6 and the detection result of the second detector 8, the angle θA of the first surface 2a of the shade member 2 with respect to the line of sight I of the driver M directed to the shade member 2 is specified. can do. The angle identification circuit 51 operates in accordance with, for example, software including the procedure of specifying the angle θA in this way.

The data correction circuit 52 corrects the imaging data based on the difference Δθ of the angle θA with respect to a predetermined reference angle (hereinafter, the reference angle will be described as 90 degrees). As shown in FIG. 11A, when the angle θA is 90 degrees (Δθ is zero, the first surface 2a of the shade member 2 and the line of sight I are orthogonal to each other), as illustrated in the diagram on the left side of FIG. 11A. The image of the traffic light S1 displayed on the display device 3 is almost properly captured by the eyes of the driver M. However, as shown in FIG. 11B, when the angle θA is an angle other than 90 degrees, the image of the traffic light S1 has a vertically distorted and distorted shape, as shown in the diagram on the left side of FIG. 11B. It is captured by the eyes of the driver M. Based on the difference Δθ between the predetermined reference angle and the angle θA, the data correction circuit 52 properly captures the image displayed on the display device 3 with the eyes of the driver M even in the state shown in FIG. 11B. As described above, the imaging data is corrected.

For example, the data correction circuit 52 replaces the data of the pixel two pixels above the central pixel in the vertical direction of the area displayed on the display device 3 in the imaged data with the data of the pixel one pixel above the central pixel. The data of the pixel three pixels above and four pixels above the central pixel are replaced with the data of the pixel two pixels above the central pixel (data before replacement as described above). The data correction circuit 52 performs such data correction on the imaging data corresponding to the area to be displayed on the display device 3 in both up and down directions. By performing such a correction, the image displayed on the display device 3 can be doubled vertically. The magnification for vertically stretching the display image is selected based on the difference Δθ in the angle θA with respect to the predetermined reference angle. For example, the display image is stretched in the vertical direction with a greater magnification as the angle θA of the first surface 2a of the shade member 2 with respect to the line of sight of the driver M is further away from 90 degrees.

The data processing circuit 5 generates display image data in the data generation circuit 50 based on the imaged data that has been corrected by the data correction circuit 52. By doing so, for example, an image stretched in the vertical direction is displayed on the actual display device 3, as shown in FIG. 12A. However, as shown in FIG. 12B, the driver perceives it as an image having a shape close to the original shape of the display object (traffic light S1 in FIG. 12B). It is considered that the driver can easily recognize the display object. The data correction circuit 52 may correct the display image data generated by the data generation circuit 50.

Next, the function of the display target data selection circuit 53 (see FIG. 10) will be described with reference to FIGS. 13 and 14. As shown in FIG. 13, the position of the eyes of the driver M moves according to changes in the posture of the driver and the like. Therefore, in the field of view of the driver M, the blind spot portion created by the shade member 2 may also change at any time. It is considered preferable to display only the scene of the blind spot on the display device 3 in order to display an image without a sense of discomfort in the eyes of the driver M.

As shown in FIG. 13, if the reference position PR of the awning member 2 and the reference position PI of the eyes of the driver M are assumed, based on these and the size of the awning member 2, the imaging area of the imaging device 4 in the imaging area. The blind spot (reference blind spot BR) is determined. The imaging area is fixedly determined by the position and characteristics of the imaging device 4. If the positions of the awning member 2 and the eyes of the driver M are fixed, the area corresponding to the reference blind spot portion BR (reference display target area) in the imaging data is set as the display target area, so that the blind spot portion is always displayed. Only the scene is displayed on the display device 3. However, the positions of the sunshade member 2 and the eyes of the driver M move, and the blind spot part changes accordingly. Therefore, it is preferable to change the display target area according to the variation of the blind spot. For such a display, the display target data selection circuit 53 determines a blind spot portion blocked by the shade member 2 in the field of view of the operator of the shade member 2 (driver M in the present embodiment), and the image data Select the display target data corresponding to the blind spot part of.

The first detector 6 and the second detector 8 are connected to the display target data selection circuit 53 (see FIG. 10). Therefore, the display target data selection circuit 53 is input with information about the position of the shade member 2 and the position of the eyes of the driver M. Further, the display target data selection circuit 53 includes a memory circuit 53a (see FIG. 10). In the memory circuit 53a, the difference between the blind spot portion BA generated by being blocked by the shade member 2 and the reference blind spot portion BR for each position and/or angle of the various shade members 2 and each position of the eyes of the driver M. Information is stored. FIG. 13 shows the blind spot portion BA when the eyes of the driver M are at the position PA as an example. For example, the memory circuit 53a stores the amount of movement in the up-down direction and the left-right direction with respect to the reference blind spot portion BR, the enlargement ratio or the reduction ratio, etc., which is necessary to obtain the actual position of the blind spot portion BA. The display target data selection circuit 53 is actually based on the information about the position of the shade member 2 and the position of the driver's M eye from the first and second detectors 6 and 8 and the stored contents of the memory circuit 53a. The position of the blind spot BA of is specified by numerical calculation or the like. Then, the display target data selection circuit 53 selects the data of the area corresponding to the actual blind spot portion BA in the imaged data as the display target data to be the display target.

Then, the data generation circuit 50 generates display image data based on the selected display target data in order to display the actual scene of the blind spot portion BA on the display device 3. As a result, as shown in FIG. 14, the actual display is changed (shifted upward in the example of FIG. 14) with respect to the reference display target region DR corresponding to the reference blind spot portion in the imaging region 41. The image of the display target area DA to be displayed is displayed on the display device 3. It is possible to display on the display device 3 an image with less discomfort in comparison with the scene seen through the windshield.

Note that the display target data selection circuit 53 may have a function of canceling a fine shake of image display caused by a slight movement of the driver M relative to the vehicle body. For example, when the information from the second detector 8 (see FIG. 10) frequently changes above a predetermined level, the display target data selection circuit 53 lengthens the cycle for sampling the information from the second detector 8. May be configured to do so. Further, the display target data selection circuit 53 may be configured not to newly start the display target data selection operation when the change in the eye position of the driver M does not satisfy a predetermined condition. Further, a low-pass filter may be provided in the input portion of the display target data selection circuit 53 that receives the information from the second detector 8.

Next, the functions of the display image enhancement circuit 56, the comparison circuit 55 and the memory circuit 54 (see FIG. 10) will be described with reference to FIGS. 15, 16A and 16B.

The memory circuit 54 stores reference data regarding the external characteristics of a predetermined object that can be imaged by the imaging device 4 (see FIG. 1). FIG. 15 conceptually shows an example of the reference data 54a, 54b stored in the memory circuit 54 as an image that can be reconstructed by the reference data 54a, 54b. That is, as shown in FIG. 15, the memory circuit 54 stores, as data, appearance features of an object that may be captured by the imaging device 4, such as the traffic light S1 and the regulation sign S2. For example, the memory circuit 54 stores image pickup data generated by actually photographing the traffic light S1 and the like with the image pickup device 4. Alternatively, the reference data 54a and 54b may be formed by modeling the shape of the traffic light S1 or the like using unit elements such as minute triangles and using the vertex coordinates of each unit element. The reference data can be formed in any way. Although not particularly limited, the memory circuit 54 is composed of, for example, an arbitrary semiconductor memory device such as SRAM or PROM. The same storage device may be shared with the memory circuit 53a of the display target data selection circuit 53 described above.

The comparison circuit 55 compares the image pickup data generated by the image pickup device 4 with the reference data 54a and 54b stored in the memory circuit 54. The comparison circuit 55 may, for example, reconstruct the imaging data and the reference data 54a and 54b into an image and compare them by a pattern recognition technique. Further, if the image data and the reference data 54a and 54b have the same data format, the two data may be sequentially compared in the unit of bit or byte without changing the actual data. The comparison method performed by the comparison circuit 55 is not particularly limited. The comparison circuit 55 detects the approximate image pickup data by comparing the image pickup data with the reference data 54a and 54b, and if there is approximate image pickup data that is close to either the reference data 54a or 54b so as to satisfy a predetermined criterion. To do.

The display image emphasizing circuit 56 emphasizes the display image of the predetermined object displayed based on the approximate imaging data over the other display images when the approximate imaging data is detected as a result of the comparison of the comparison circuit 55. Display on the display device 3. Specifically, the display image emphasizing circuit 56 processes the display image data generated based on the approximate image pickup data among the display image data generated by the data generating circuit 50 (see FIG. 10).

For example, as shown on the left side of the display device 3 in FIG. 16A, the display image enhancement circuit 56 processes the data of the pixels around the image S11 of the enhancement target (traffic light), and the image S11 is made to stand out. A frame S12 surrounding the is displayed. Further, as shown on the right side of the display device 3 in FIG. 16A, the data of the pixels around the image S21 of the emphasis target (regulation sign) may be processed and the enlarged image S22 of the image S21 may be displayed. In addition, as shown in FIG. 16B, the display image enhancement circuit 56 enhances the brightness of the sub-pixel of the specific color in order to emphasize the specific color (for example, red or blue) in the display images S11 and S21 of the enhancement target. May be increased.

Further, when the approximate image pickup data is detected, the display image enhancing circuit 56 causes the display device 3 to display an image to be displayed based on the image pickup data including the approximate image pickup data as a still image in a predetermined time frame. May be. For example, the display image data generated by the data generating circuit 50 is recorded in a video memory (not shown) or the like as needed. Then, when the approximate image pickup data is detected, the display image data sent to the display device 3 is recorded in a video memory (not shown) from the display image data generated by the data generation circuit 50 at any time for a predetermined time. The display image data may be switched to the displayed image data. The display image enhancing circuit 56 is not limited to these methods and can enhance a specific image in any method. With such emphasis, the visibility of an object that the driver M needs to recognize can be enhanced.

FIG. 17 illustrates a cross-sectional view of one pixel of the organic EL display panel 30 that constitutes the display device 3 of the sunshade device 1. A switch element such as a TFT 38 is formed for each of R, G, and B sub-pixels on a flexible film 37 made of resin or the like, and a first electrode (for example, an anode) is formed on a flattening film 31 formed thereon. ) 32 is formed. The first electrode 32 is formed of, for example, a combination of a metal film such as Ag and an ITO film, and is connected to a switch element such as a TFT 38. An insulating bank 33 made of SiO ₂ or the like is formed between the sub-pixels. An organic layer 34 is vapor-deposited on the region surrounded by the insulating bank 33. Although the organic layer 34 is shown as a single layer in FIG. 17, the organic layer 34 may actually be formed of a laminated film of a plurality of layers made of different organic materials.

A second electrode (for example, a cathode) 35 is formed on the organic layer 34 by, for example, depositing Mg and Ag, Al, or the like on the entire surface. Further, a protective film 36 made of, for example, Si ₃ N ₄ is formed on the surface of the second electrode 35. Each element shown in FIG. 17 is wholly sealed by a sealing layer made of a resin film or the like (not shown) so that the organic layer 34 and the second electrode 35 do not absorb moisture, oxygen and the like. Note that the cross-sectional structure shown in FIG. 17 is merely an example, and the structure of the organic EL display panel 30 forming the display device 3 and the material of each component are not limited to the structures and materials described here.

In the organic EL display panel 30 used in the awning device 1 of the present embodiment, the first electrode 32 and the second electrode 35 are formed at substantially the same intervals in each of the R, G, and B sub-pixels. Has been done. In other words, the first electrode 32 and the second electrode 35 are not intentionally made different from each other in the interval between the sub-pixels of each color. On the other hand, in general, in an organic EL display panel, in order to increase the intensity of light emitted in a direction perpendicular to the display surface of the panel, light emitted from the organic layer is repeatedly reflected between the anode and the cathode. The distance between the anode and the cathode of the sub pixel is matched with the wavelength of the light of the color emitted by the sub pixel (microcavity structure). That is, in a general organic EL display panel, the distance between the anode and the cathode is different for each subpixel of each color.

On the other hand, in the awning device 1 of the present embodiment, the display device 3 is seen by the driver M from any angle, as described above. Therefore, increasing the intensity of the light emitted in the direction perpendicular to the display surface of the display device 3 is not very useful, and rather R, G is adjusted so that the chromaticity does not change significantly even if the angle changes. It is more important to match the viewing angle dependence of each color of B and B. Therefore, unlike the general organic EL display panel, the first electrode 32 and the second electrode 35 of the organic EL display panel 30 used in the awning device 1 of the present embodiment do not utilize the microcavity effect. For example, the first electrode 32 and the second electrode 35 may be separated by substantially the same distance between the R, G, and B sub-pixels. In other words, the distance between the cathode and the anode in each sub pixel does not have to match the wavelength of the light emitted by that sub pixel. That is, the organic EL display panel 30 includes a plurality of sub-pixels, and each of the plurality of sub-pixels has two electrodes arranged with an interval different in length from the wavelength of light emitted by each of the plurality of sub-pixels. May be included.

In the above description, the awning device 1 of the present embodiment has been described by taking the case where it is used for the windshield of an automobile as an example. However, the awning device 1 according to the present embodiment is not limited to the windshield, but may be the rear glass of an automobile, the window glass of any vehicle, or, as described above, the window of any other vehicle and any building. It should be understood that it is compatible with glass.

18 and 19 show the image display module 11 according to the first embodiment of the present invention. The image display module 11 includes substantially the same components as the awning device 1 except the awning member 2 of the awning device 1 (see FIG. 2) of the first embodiment. That is, the image display module 11 includes the display device 13 that should be arranged with the display unit 13a facing the operator M. The display device 13 is arranged on the surface Xa that faces the operator M when the display device 13 is used in the awning device X that does not include a display device. Since the awning device X does not include the display device 3, the imaging device 4, the data processing circuit 5 and the like included in the awning device 1 of the first embodiment, only the structure and function corresponding to the awning member 2 are provided. And has a surface Xa facing the operator M at the time of use. Furthermore, the image display module 11 captures an area of the awning apparatus X facing the surface opposite to the surface Xa and generates imaging data, and based on the imaging data generated by the imaging apparatus 14, the awning apparatus X And a data processing circuit 15 that generates display image data to be displayed on the display unit 13a during use. According to the image display module 11 of the first embodiment, when the sunshade device X is used, a scene including a region hidden by the sunshade device X can be caught by an operator of the sunshade device X.

The display device 13 is preferably composed of an organic EL display panel or a liquid crystal display panel, like the display device 3 of the awning device 1 of the first embodiment. The display device 13 is attached to the surface Xa of the awning device X when the awning device X is used. 18 and 19, the display device 13 is bonded and fixed to the surface Xa of the awning device X having a curved surface portion near the edge by using, for example, an adhesive sheet. The display device 13 extends to the curved surface portion of the surface Xa. Therefore, the display device 13 has flexibility. However, the display device 13 may have rigidity. As shown in FIG. 19, the display device 13 may be bonded to the support body 13b so as to have constant mechanical strength even when the display device 13 is not attached to the sunshade device X. The support 13b is formed of any synthetic resin or the like.

The imaging device 14 and the data processing circuit 15 can be configured similarly to the imaging device 4 and the data processing circuit 5 of the awning device 1 of the first embodiment. As shown in FIG. 18, the imaging device 14 is connected to the display device 13 (specifically, the data processing circuit 15) by wire or wirelessly.
