The region A3 is a portion of the region A leftward of the position C3 of the marine vessel operator's viewpoint Q (operation seat 4) in the left-right direction. The region A4 is a portion of the region A rightward of the position C3.

(27) As shown in FIG. 4, in the first preferred embodiment, the sum of angular ranges 1 to 8 of the region A in the horizontal direction around the operation seat 4 in a plan view is about 90 degrees or more and about 360 degrees or less. That is, the sum of the angular range 1 of the region A1 (A3) generated due to the front pillar 12a, the angular range 2 of the region A1 (A4) generated due to the front pillar 12b, the angular range 3 of the region A2 (A3) generated due to the rear pillar 13a, the angular range 4 of the region A2 (A4) generated due to the rear pillar 13b, the angular range 5 of the region A1 (A3) generated due to the front wall 14a, the angular ranges 6a and 6b of the region A2 (A4) generated due to the rear wall 14b, the angular range 7 of the region A2 (A3) generated due to the left wall 14c, and the angular range 8 of the region A2 (A4) generated due to the right wall 14d around the marine vessel operator's viewpoint Q is about 90 degrees or more and about 360 degrees or less. Preferably, for example, the sum of the angular ranges 1 to 8 is about 180 degrees or more and about 360 degrees or less.

(28) In the region A1, the sum of the angular ranges 1, 2, and 5 is about 60 degrees or more and about 180 degrees or less. In the region A2, the sum of the angular ranges 3, 4, 6a, 6b, 7, and 8 is about 60 degrees or more and about 180 degrees or less. In the region A3, the sum of the angular ranges 1, 3, 5, 6a, and 7 is about 60 degrees or more and about 180 degrees or less. Preferably, for example, the sum of the angular ranges 1, 3, 5, 6a, and 7 is about 120 degrees or more and about 180 degrees or less. In the region A4, the sum of the angular ranges 2, 4, 6b, and 8 is about 60 degrees or more and about 180 degrees or less. Preferably, for example, the sum of the angular ranges 2, 4, 6b, and 8 is about 120 degrees or more and about 180 degrees or less.

(29) As shown in FIGS. 5 and 6, when the marine vessel operator visually recognizes a position below the horizontal direction from the marine vessel operator's viewpoint Q, a region in which the marine vessel operator's field of view is obstructed by the shield 20 of the cabin 10, the front deck 10a, and the rear deck 10b is defined as a lower field-of-view shielded region A5 (hereinafter referred to as a region A5). The horizontal direction refers to a direction along a plane parallel or substantially parallel to the water surface W.

(30) As shown in FIG. 7, the marine vessel operation support device 3 is a device that supports the marine vessel operation of the marine vessel operator located on the operation seat 4 inside the cabin 10. Specifically, the marine vessel operation support device 3 includes an imager 6, an image processor 30, a display 40, and a controller 50. In other words, the marine vessel operation support device 3 displays an image captured by the imager 6 on the display 40 when the marine vessel operator operates the marine vessel operation unit 5 (operates the marine vessel) while being located on the operation seat 4 to complement the marine vessel operator's field of view (blind spot).

(31) The imager 6 images the region A (A1 to A5). Furthermore, the imager 6 images at least a portion of each of the regions A1 to A5. Specifically, as shown in FIG. 1, the imager 6 is located on the hull 1 and is provided outward from the hull 1. The imager 6 images the regions A1 to A4 by imaging in all directions (the angular range is about 360 degrees) outward from the hull 1. That is, the imager 6 is a single camera or an omnidirectional camera including a plurality of cameras. The imager 6 images the region A5 by imaging from the upper side of the hull 1 toward the lower side of the hull 1. The imager 6 transmits a captured image P1 (images of the regions A1 to A5) to the image processor 30. In FIG. 1, the imager 6 is located on an upper portion of the cabin 10, but the imager 6 may be provided at any position on the hull 1 as long as the region A is imaged.

(32) The image processor 30 generates a field-of-view complement image P2 to be displayed on the display 40 based on the image P1 of the region A captured by the imager 6. When the captured image P1 is able to be displayed on the display 40, the image P1 and the field-of-view complement image P2 may be the same or substantially the same. Furthermore, the field-of-view complement image P2 may include a bird's-eye view image that shows the periphery of the hull 1 from the upper side toward the lower side in a bird's-eye view.

(33) For example, as shown in FIG. 8, the image processor 30 generates a front image P21 (the image of the region A1), a rear image P22 (the image of the region A2), and a left image P23 (the image of the region A3), a right image P24 (the image of the region A4), a left front image P25 (the images of the regions A1 and A3) between the left side and the front side, a left rear image P26 (the images of the regions A2 and A3) between the left side and the rear side, a right front image P27 (the images of the regions A1 and A4) between the right side and the front side, and a right rear image P28 (the images of the regions A2 and A4) between the right side and the rear side based on the image P1. That is, the field-of-view complement image P2 includes the front image P21, the rear image P22, the left image P23, the right image P24, the left front image P25, the left rear image P26, the right front image P27, and the right rear image P28. The image processor 30 outputs the generated field-of-view complement image P2 to the display 40 based on a command from the controller 50.

(34) The display 40 is located adjacent to or in a vicinity of the operation seat 4. Specifically, the display 40 is provided inside the cabin 10 and at a position visible from the operation seat 4. The display 40 is provided inside the cabin 10 at a position at which the display 40 is viewable by the marine vessel operator located on the operation seat 4 when the marine vessel operator looks at the outside of the hull 1 at least in a forward and horizontal direction. For example, the display 40 is provided on the operation seat 4 side of the console 5c. The display 40 includes a first portion 41, a second portion 42, a third portion 43, a fourth portion 44, a fifth portion 45, a sixth portion 46, a seventh portion 47, and an eighth portion 48. Furthermore, the first portion 41, the second portion 42, the third portion 43, the fourth portion 44, the fifth portion 45, the sixth portion 46, the seventh portion 47, and the eighth portion 48 may be provided as separate displays, or as different display areas of a single display.

(35) For example, the first portion 41, the second portion 42, the third portion 43, the fourth portion 44, the fifth portion 45, the sixth portion 46, the seventh portion 47, and the eighth portion 48 are provided in an annular shape. Specifically, in the display 40, the first portion 41 is provided at an upper portion, the second portion 42 is provided at a lower portion, the third portion 43 is provided at a left portion, the fourth portion 44 is provided at a right portion, the fifth portion 45 is provided at a portion between the upper side and the left side, the sixth portion 46 is provided at a portion between the lower side and the left side, the seventh portion 47 is provided at a portion between the upper side and the right side, and the eighth portion 48 is provided at a portion between the lower side and the right side.

(36) The display 40 displays the field-of-view complement image P2. For example, the display 40 displays the front image P21, the rear image P22, the left image P23, the right image P24, the left front image P25, the left rear image P26, the right front image P27, and the right rear image P28 at the same time or at substantially the same time. Specifically, the display 40 displays the front image P21 on the first portion 41, displays the rear image P22 on the second portion 42, displays the left image P23 on the third portion 43, displays the right image P24 on the fourth portion 44, displays the left front image P25 on the fifth portion 45, displays the left rear image P26 on the sixth portion 46, displays the right front image P27 on the seventh portion 47, and displays the right rear image P28 on the eighth portion 48.

(37) The controller 50 is a control processing circuit including a central processing unit (CPU) and a memory, for example. The controller 50 controls each portion of the marine vessel operation support device 3. The controller 50 controls the display 40 to display the field-of-view complement image P2 by transmitting a control signal to the image processor 30 and the display 40.

(38) According to the first preferred embodiment of the present invention, the following advantageous effects are able to be provided.

(39) According to the first preferred embodiment, the marine vessel 100 includes the imager 6 that images the region A and the display 40 provided at the position visible from the operation seat 4 and that displays the field-of-view complement image P2, which is the image of the region A. Accordingly, the image of the region A is visually recognized by the marine vessel operator located on the operation seat 4 provided inside the cabin 10, and thus the marine vessel operator's field of view is complemented. Consequently, even when the operation seat 4 is provided inside the cabin 10, marine vessel operator's visibility to the outside of the marine vessel is improved without greatly changing the designs or shapes of structural members of the cabin 10. Furthermore, the operation seat 4 is provided inside the cabin 10, and thus blowing of the wind against the marine vessel operator is significantly reduced or prevented, and the temperature adjacent to or in a vicinity of the operation seat 4 is easily maintained at an appropriate temperature.

(40) According to the first preferred embodiment, the display 40 is located adjacent to or in a vicinity of the operation seat 4. Accordingly, the marine vessel operator located on the operation seat 4 easily visually recognizes the display 40 provided adjacent to or in a vicinity of the operation seat 4.

(41) According to the first preferred embodiment, the imager 6 images at least the region A1. Furthermore, the display 40 displays the field-of-view complement image P2 including the front image P21 of the region A1. Accordingly, the marine vessel operator's field of view is complemented when the marine vessel 100 is traveling forward. Consequently, when the marine vessel operator is operating the marine vessel 100 in the cabin 10 and the marine vessel 100 moves forward (during sailing), the marine vessel operator's visibility to the outside of the marine vessel is improved.

(42) According to the first preferred embodiment of the present invention, the imager 6 images the region A2 in addition to the region A1. Furthermore, the display 40 displays the field-of-view complement image P2 including the front image P21 of the region A1 and the rear image P22 of the region A2. Accordingly, the marine vessel operator's visibility to the outside of the marine vessel not only forward of the hull 1 but also rearward of the hull 1 is improved.

(43) According to the first preferred embodiment, the front window 15a is provided in front of the operation seat 4 in the cabin 10. Furthermore, the region A includes the regions (regions A1 to A4) in which the marine vessel operator's field of view is obstructed when the marine vessel operator looks at the outside of the marine vessel in the horizontal direction from the height of the center position C1 of the front window 15a in the vertical direction above the operation seat 4. Accordingly, the field of view of the marine vessel operator located on the operation seat 4 and who is visually recognizing the front window 15a is complemented. Consequently, the marine vessel operation of the marine vessel operator is effectively supported when the marine vessel travels forward.

(44) According to the first preferred embodiment, the region A includes the regions (regions A1 to A4) obstructed by the shield 20 including the front pillars 12a and 12b of the cabin 10 and the rear wall 14b of the cabin 10. Accordingly, the marine vessel operator's field of view obstructed by the shield 20 of the cabin 10 is complemented. Consequently, the operation seat 4 is provided inside the cabin 10 and, even when the region A is generated due to components or elements of the cabin 10, the marine vessel operator's field of view is effectively complemented.

(45) According to the first preferred embodiment, the sum of the angular ranges 1 to 8 of the region A in the horizontal direction around the operation seat 4 in the plan view is about 90 degrees or more and about 360 degrees or less. Accordingly, when the marine vessel operator located on the operation seat 4 looks over in the horizontal direction, the marine vessel operator's field of view is complemented even when the region A is relatively large (for example, even when the sum of the angular ranges 1 to 8 is about 90 degrees or more). Consequently, as compared with a case in which the region A is relatively small (for example, the sum of the angular ranges 1 to 8 is less than about 90 degrees), the marine vessel operation of the marine vessel operator is more effectively supported.

(46) According to the first preferred embodiment, the sum of the angular ranges 1 to 8 of the region A is about 180 degrees or more and about 360 degrees or less. Accordingly, even when the region A is even larger (when the sum of the angular ranges 1 to 8 is about 180 degrees or more), the marine vessel operator's field of view is complemented. Consequently, the marine vessel operation of the marine vessel operator is more effectively supported.

(47) According to the first preferred embodiment, the sum of the angular ranges 1, 2, and 5 of the region A1 in the horizontal direction around the operation seat 4 in the plan view is about 60 degrees or more and about 180 degrees or less. Accordingly, even when the region A1 is relatively large (for example, even when the sum of the angular ranges 1, 2, and 5 is about 60 degrees or more), the marine vessel operator's visibility to an area forward of the hull 1 is improved without greatly changing the designs or shapes of the front structural members (the front pillars 12a and 12b, the front wall 14a, etc.) of the cabin 10 and the members provided inside the cabin 10.

(48) According to the first preferred embodiment, the sum of the angular ranges 3, 4, 6a, 6b, 7, and 8 of the region A2 in the horizontal direction around the operation seat 4 in the plan view is about 60 degrees or more and about 180 degrees or less. Accordingly, even when the region A2 is relatively large (the sum of the angular ranges 3, 4, 6a, 6b, 7, and 8 is about 60 degrees or more), the marine vessel operator's visibility to an area rearward of the hull 1 is improved without greatly changing the designs or shapes of the rear structural members (the rear pillars 13a and 13b and the rear wall 14b) of the cabin 10 and the members provided inside the cabin 10.

(49) According to the first preferred embodiment, the sum of the angular ranges 1, 3, 5, 6a, and 7 (angular ranges 2, 4, 6b, and 8) of the region A3 (region A4) in the horizontal direction around the operation seat 4 in the plan view is about 60 degrees or more and about 180 degrees or less. Accordingly, even when the region A3 (region A4) is relatively large (the sum of the angular ranges 1, 3, 5, 6a, and 7 (angular ranges 2, 4, 6b, and 8) is about 60 degrees or more), the marine vessel operator's visibility to an area leftward or rightward of the hull 1 is improved without greatly changing the designs or shapes of the left or right structural members (the left wall 14c or right wall 14d) of the cabin 10 and the members provided inside the cabin 10.

(50) According to the first preferred embodiment, the sum of the angular ranges 1, 3, 5, 6a, and 7 (angular ranges 2, 4, 6b, and 8) of the region A3 (region A4) in the horizontal direction around the operation seat 4 in the plan view is about 120 degrees or more and about 180 degrees or less, for example. Accordingly, even when the region A3 (region A4) is even larger (the sum of the angular ranges 1, 3, 5, 6a, and (angular ranges 2, 4, 6b, and 8) is about 120 degrees or more), the marine vessel operator's visibility to the area leftward or rightward of the hull 1 is improved without greatly changing the designs or shapes of the left or right structural members of the cabin 10 and the members provided inside the cabin 10.

(51) The structure of a marine vessel 200 according to a second preferred embodiment of the present invention is now described with reference to FIGS. 9 and 10. In the second preferred embodiment, displays 241 and 242 are located on a shield 20 that generates a region A. In the second preferred embodiment, the same or similar structures as those of the first preferred embodiment are denoted by the same reference numerals, and description thereof is omitted.

(52) The marine vessel 200 includes a marine vessel operation support device 203, as shown in FIG. 9. The marine vessel operation support device 203 includes an image processor 230, the displays 241 and 242, and a controller 250.

(53) As shown in FIG. 10, the displays 241 and 242 are located on the shield 20 that generates the region A. The displays 241 and 242 display a field-of-view complement image P102 including an image of the region A generated due to the displays 241 and 242.

(54) Specifically, the display 241 is provided on surfaces of a front pillar 12a and a front wall 14a on the operation seat 4 side (inside a cabin 10). Furthermore, the display 241 displays the field-of-view complement image P102 including a front image P21 and a left front image P25 of regions A1 and A3 generated due to the front pillar 12a and the front wall 14a on which the display 241 is provided.

Accordingly, a marine vessel operator visually recognizes the displays 241 and 242 provided on the shield 20 and thus the marine vessel operator visually recognizes the image corresponding to the region A generated due to the shield 20. Therefore, the marine vessel operator visually recognizes the field-of-view complement image P102 and is able to see through the shield 20, and thus marine vessel operator's visibility to the outside of the marine vessel is further improved.

(60) According to the second preferred embodiment, the displays 241 and 242 are provided on the surface of the shield 20 on the operation seat 4 side. Accordingly, the displays 241 and 242 are provided on the surface of the shield 20 on the operation seat 4 side while the region in which the shield 20 is provided is effectively used such that the marine vessel operator located on the operation seat 4 more easily recognizes the displays 241 and 242. The remaining advantageous effects of the second preferred embodiment are similar to those of the first preferred embodiment.

That is, the display 340 defines and functions as a virtual window. The image processor 330 generates the field-of-view complement image P202. The controller 350 controls the image processor 330 to output the field-of-view complement image P202 to the display 340. The remaining structures of the third preferred embodiment are similar to those of the first preferred embodiment.

(66) According to the third preferred embodiment, the following advantageous effects are able to be provided.

(67) According to the third preferred embodiment, the display 340 is provided inside the cabin 10 at the position at which the display 340 is viewable by the marine vessel operator located on the operation seat 4 when the marine vessel operator looks at the outside of the marine vessel at least in the forward and horizontal direction. Accordingly, the marine vessel operator who is looking forward visually recognizes the display 340. Consequently, the visibility, to the outside of the marine vessel, of the marine vessel operator who is operating the marine vessel while looking forward is improved.

(68) According to the third preferred embodiment, the display 340 is provided over the entire inner periphery of the cabin 10. Accordingly, the marine vessel operator's field of view is complemented over the entire inner periphery (wall 311) of the cabin 10. That is, when looking over the entire inner periphery of the cabin 10, the marine vessel operator visually recognizes the field-of-view complement image P202 showing the entire region A10. The remaining advantageous effects of the third preferred embodiment are similar to those of the first preferred embodiment.
