[0012] A display control device according to one embodiment of the present disclosure includes an acquisition unit that acquires a driving condition of a vehicle, a determination unit that determines whether to enlarge the first image displayed on a display unit arranged on the vehicle, the first image being cropped from a captured image of the rear side of the vehicle based on the driving condition acquired by the acquisition unit, and a control unit that, when it is determined by the determination unit to enlarge the first image, enlarges the first image by increasing a cropping range for cropping the first image from the captured image, and displays the enlarged first image on the display unit.

[0013] According to this, the first image can be enlarged by increasing the trimming range for trimming the first image from the captured image of the rear side of the vehicle, and the enlarged first image can be displayed on the display unit. Therefore, the rear side of the vehicle can be visually recognized over a wider range, making it easier to check the rear side of the vehicle.

[0014] In addition, in a display control device according to one aspect of the present disclosure, the captured image is an image captured behind one side of the vehicle in the left-right direction, the display unit has a first display that is located forward of the driver's seat of the vehicle in the fore-and-aft direction of the vehicle and to the one side of the center in the left-right direction and displays an image so that it can be seen from the driver's seat, and the determination unit determines that the first image displayed on the first display should be enlarged when the vehicle is about to move to the one side or the vehicle is about to reverse, and when the determination unit determines that the first image should be enlarged, the control unit enlarges the first image by increasing the cropping range and displays the enlarged first image on the first display.

[0015] According to this, when the vehicle is moving to one side or reversing, the enlarged first image can be displayed on the first display. Therefore, when the vehicle is moving to one side or reversing, the rear of the vehicle can be easily viewed over a wider range, making it even easier to check the rear side of the vehicle.

[0016] In addition, in a display control device according to one embodiment of the present disclosure, the display unit has a second display that is located on the other side of the first display in the left-right direction, is located in the center, and displays an image so that it can be seen from the driver's seat, and the determination unit determines that the first image displayed on the first display should be enlarged when the vehicle is about to move to one side, and when the determination unit determines that the first image should be enlarged, the control unit enlarges the first image by increasing the trimming range on the one side and displays the enlarged first image across the first display and the second display.

[0017] According to this, when the vehicle is about to move to one side, the enlarged first image can be displayed across the first display and the second display. Therefore, when the vehicle is about to move to one side, the rear of the vehicle on one side can be more easily viewed over a wider range, making it easier to check the rear side of the vehicle.

[0018] In addition, in a display control device according to one embodiment of the present disclosure, when the control unit displays the enlarged first image across the first display and the second display, if a second image is displayed on the second display, the control unit may reduce the size of the second image by shrinking at least a portion of the second image in the left-right direction, and display the reduced size second image in an area of ​​the second display where the first image is not displayed.

[0019] This allows the second image to be displayed together with the enlarged first image without deleting the second image, thereby preventing a decrease in the amount of information obtained from the second image and making it easier to check the rear side of the vehicle.

[0020] In addition, in a display control device according to one embodiment of the present disclosure, when the control unit displays the enlarged first image across the first display and the second display, if a second image is displayed on the second display, the control unit may reduce the size of the second image by removing a portion of the second image from the second display, and display the reduced size second image in an area of ​​the second display where the first image is not displayed.

[0021] This allows the second image to be displayed together with the enlarged first image without reducing the scale of the portion of the second image that is not deleted, making it easy to visually confirm the portion of the second image that is not deleted, and to easily check the rear side of the vehicle.

[0022] In addition, in a display control device according to one embodiment of the present disclosure, when the control unit displays the enlarged first image across the first display and the second display, if a second image including multiple images lined up in the left-right direction is displayed on the second display, the control unit may reduce the size of the second image by shrinking each of the multiple images in the vertical direction of the vehicle and arranging the multiple images side by side in the vertical direction, and display the reduced size second image in an area of ​​the second display where the first image is not displayed.

[0023] This allows the second image to be displayed together with the enlarged first image without deleting the second image, thereby preventing a decrease in the amount of information obtained from the second image and making it easier to check the rear side of the vehicle.

[0024] In addition, in a display control device according to one embodiment of the present disclosure, when the control unit displays the enlarged first image across the first display and the second display, if a second image is displayed on the second display, the control unit may display the portion of the enlarged first image that is displayed on the second display superimposed on the second image.

[0025] This allows the second image to be displayed together with the enlarged first image without reducing the scale of the portion of the second image that is not superimposed on the first image, making it easy to view the portion of the second image that is not superimposed on the first image and to easily check the rear side of the vehicle.

[0026] In addition, in a display control device according to one embodiment of the present disclosure, the display unit has a third display that is located on the other side of the second display in the left-right direction and displays an image so that it is visible from the driver's seat, and when the control unit causes the enlarged first image to be displayed across the first display and the second display, if a second image is displayed on the second display and a third image is displayed on the third display, the control unit may cause the second image to be displayed across an area of ​​the second display where the first image is not displayed and the third display, make the third image smaller by deleting a portion of the third image from the third display, and display the reduced-size third image in the area of ​​the third display where the second image is not displayed.

[0027] According to this, the second image and the third image can be displayed together with the enlarged first image without deleting the second image and without reducing the scale of the portion of the third image that is not deleted. Therefore, it is possible to prevent a decrease in the amount of information obtained from the second image, and it is possible to easily view the portion of the third image that is not deleted and to easily check the rear side of the vehicle.

[0028] In addition, in a display control device according to one embodiment of the present disclosure, the display unit has a fourth display that is located on one side of the first display in the left-right direction and displays an image so that it is visible from the driver's seat, and the determination unit determines that the first image displayed on the first display should be enlarged when the vehicle is about to move to the one side, and when the determination unit determines that the first image should be enlarged, the control unit enlarges the first image by increasing the trimming range on the one side and displays the enlarged first image across the first display and the fourth display.

[0029] According to this, when the vehicle is about to move to one side, the enlarged first image can be displayed across the first and fourth displays. Therefore, when the vehicle is about to move to one side, the rear of the vehicle on one side can be more easily viewed over a wider range, making it easier to check the rear side of the vehicle.

[0030] In addition, in a display control device according to one embodiment of the present disclosure, the display unit has a fifth display that is located below the first display in the vertical direction of the vehicle and displays an image so that it is visible from the driver's seat, and the determination unit determines that the first image displayed on the first display should be enlarged when the vehicle is about to reverse, and when the determination unit determines that the first image should be enlarged, the control unit enlarges the first image by increasing the trimming range on the downward side and displays the enlarged first image across the first display and the fifth display.

[0031] According to this, when the vehicle is moving backward, the enlarged first image can be displayed across the first and fifth displays. Therefore, when the vehicle is moving backward, the rear of one side of the vehicle can be more easily viewed over a wider range, making it easier to check the rear side of the vehicle.

[0032] Moreover, in a display control device according to one embodiment of the present disclosure, the captured image is an image captured behind the vehicle, and the display unit has a sixth display that is located forward of the driver's seat in the fore-and-aft direction of the vehicle, located in the center of the vehicle in the left-right direction, and displays an image so that it can be seen from the driver's seat, and a seventh display that is located forward of the driver's seat in the fore-and-aft direction, located in the center, located higher than the 6th display in the up-and-down direction of the vehicle, smaller than the 6th display, and displays an image so that it can be seen from the driver's seat, and when the vehicle is in a state where it is about to reverse, the determination unit determines to enlarge the first image displayed on the seventh display, and when the determination unit determines to enlarge the first image, the control unit may enlarge the first image by increasing the trimming range and display the enlarged first image on the sixth display.

[0033] According to this, when the vehicle is reversing, the enlarged first image can be displayed on the sixth display, so that when the vehicle is reversing, the rear of the vehicle can be easily viewed over a wider range, making it even easier to check the rear side of the vehicle.

[0034] Furthermore, a display control method according to one aspect of the present disclosure includes an acquisition step of acquiring a driving condition of a vehicle, a determination step of determining whether or not to enlarge a first image displayed on a display unit arranged on the vehicle, the first image being cropped from a captured image of the rear side of the vehicle based on the driving condition acquired by the acquisition step, and a control step of enlarging the first image by increasing a cropping range for cropping the first image from the captured image, when it is determined that the first image should be enlarged, and displaying the enlarged first image on the display unit.

[0035] This provides the same advantageous effects as the above-mentioned display control device.

[0036] Moreover, a program according to an aspect of the present disclosure is a program for causing a computer to execute the above-described display control method.

[0037] This provides the same advantageous effects as the above-mentioned display control device.

[0047] Fig. 2 is a block diagram showing the functional configuration of the display control device 10 etc. in Fig. 1. Next, the functional configuration of the vehicle 1 and the display control device 10 will be described with reference to Fig. 2.

[0048] As shown in FIG. 2, the vehicle 1 has a camera group 3, a sensor group 4, and a navigation system 5.

[0049] The camera group 3 photographs the rear side of the vehicle 1. The rear side of the vehicle 1 includes the rear of the vehicle 1, the left rear side of the vehicle 1, and the right rear side of the vehicle 1. For example, the camera group 3 has a camera that photographs the rear side of the vehicle 1, a camera that photographs the left rear side of the vehicle 1, and a camera that photographs the right rear side of the vehicle 1. The camera that photographs the rear side of the vehicle 1 is disposed at the rear of the vehicle 1. The camera that photographs the left rear side of the vehicle 1 is disposed at the left front door or the like of the vehicle 1, and photographs the left side of the vehicle 1 and the left rear side of the vehicle 1. The camera that photographs the right rear side of the vehicle 1 is disposed at the right front door or the like of the vehicle 1, and photographs the right side of the vehicle 1 and the right rear side of the vehicle 1.

[0050] The sensor group 4 detects vehicle information for determining the traveling state of the vehicle 1. For example, the sensor group 4 includes an acceleration sensor that detects the acceleration of the vehicle 1, a steering angle sensor that detects the steering angle of the steering wheel of the vehicle 1, a turn indicator sensor that detects the on / off of the turn indicator of the vehicle 1, and a shift sensor that detects the position of the shift lever of the vehicle 1.

[0051] The navigation system 5 calculates and displays a route from the current position of the vehicle 1 to a destination, and navigates the travel of the vehicle 1.

[0052] The display control device 10 includes an image acquisition unit 11, a driving state determination unit 12, an acquisition unit 13, a determination unit 14, a control unit 15, and an image output unit 16. For example, the image acquisition unit 11, the driving state determination unit 12, the acquisition unit 13, the determination unit 14, the control unit 15, and the image output unit 16 are realized by a processor, a memory, or the like.

[0053] The image acquisition unit 11 acquires images captured by the camera group 3. Specifically, the image acquisition unit 11 acquires images of the rear of the vehicle 1, images of the left rear of the vehicle 1, images of the right rear of the vehicle 1, etc. For example, the image acquisition unit 11 is communicably connected to the camera group 3 by wire or wirelessly, and acquires images captured by the camera group 3 from the camera group 3.

[0054] The running state determination unit 12 acquires vehicle information from the sensor group 4 and the navigation system 5, and determines the running state of the vehicle 1 based on the vehicle information. For example, the running state determination unit 12 is connected to the sensor group 4 and the navigation system 5 in a wired or wireless manner so as to be able to communicate with them, and acquires the vehicle information from the sensor group 4 and the navigation system 5.

[0055] For example, the vehicle information includes the acceleration of vehicle 1, the steering angle of vehicle 1, the on / off status of the turn signal of vehicle 1, the position of the shift lever of vehicle 1, and the route from the current position of vehicle 1 to the destination.

[0056] The driving state includes a state of moving forward, a state of moving left, a state of moving right, a state of moving backward, a stopped state, etc. A state of moving left includes a state of making a left turn or a state of changing lanes to the left, etc. A state of moving right includes a state of making a right turn or a state of changing lanes to the right, etc.

[0057] For example, when the acceleration of the vehicle 1 to one side in the left-right direction is equal to or greater than a predetermined value, the driving state determination unit 12 determines that the vehicle 1 is about to move to the other side in the left-right direction. In other words, when the acceleration of the vehicle 1 to the left is equal to or greater than a predetermined value, the driving state determination unit 12 determines that the vehicle 1 is about to move to the right, and when the acceleration of the vehicle 1 to the right is equal to or greater than a predetermined value, the driving state determination unit 12 determines that the vehicle 1 is about to move to the left.

[0058] Furthermore, the running state determination unit 12 determines that the vehicle 1 is about to move to one side in the left-right direction when the steering angle of the vehicle 1 to one side in the left-right direction is equal to or greater than a predetermined value. In other words, the running state determination unit 12 determines that the vehicle 1 is about to move to the left when the steering angle of the vehicle 1 to the left is equal to or greater than a predetermined value, and determines that the vehicle 1 is about to move to the right when the steering angle of the vehicle 1 to the right is equal to or greater than a predetermined value.

[0059] Furthermore, when a direction indicator on one of the left and right directions of the vehicle 1 is turned on, the running state determination unit 12 determines that the vehicle 1 is about to move to one of the left and right directions. That is, when a direction indicator on the left side of the vehicle 1 is turned on, the running state determination unit 12 determines that the vehicle 1 is about to move to the left, and when a direction indicator on the right side of the vehicle 1 is turned on, the running state determination unit 12 determines that the vehicle 1 is about to move to the right.

[0060] Furthermore, when the shift lever of the vehicle 1 is in the reverse position, the running state determination unit 12 determines that the vehicle 1 is moving backward.

[0061] In addition, the driving state determination unit 12 determines that the vehicle 1 is attempting to move to the left when the vehicle 1 is traveling within a predetermined range including a left turn on the route from the current position of the vehicle 1 to the destination, and determines that the vehicle 1 is attempting to move to the right when the vehicle 1 is traveling within a predetermined range including a right turn.

[0062] In addition, in cases other than the above, the traveling state determination unit 12 determines that the vehicle 1 is moving forward or that the vehicle 1 is stopped.

[0063] The acquisition unit 13 acquires the driving state of the vehicle 1. In this embodiment, the acquisition unit 13 acquires the driving state determined by the driving state determination unit 12. Note that the display control device 10 does not need to include the driving state determination unit 12, and the acquisition unit 13 may acquire the driving state determined outside the display control device 10.

[0064] The determination unit 14 determines whether or not to enlarge a first image, which is a first image cropped from a captured image of the rear side of the vehicle 1 and displayed on the display unit 2 arranged on the vehicle 1, based on the traveling state acquired by the acquisition unit 13. The captured image of the rear side of the vehicle 1 is an image captured by the camera group 3.

[0065] For example, when the vehicle 1 is in a state in which it is about to move to the left or right, the determination unit 14 determines that the first image displayed on the display unit 2 arranged on the vehicle 1 should be enlarged. On the other hand, when the vehicle 1 is not in a state in which it is about to move to the left or to the right, the determination unit 14 determines that the first image displayed on the display unit 2 arranged on the vehicle 1 should not be enlarged.

[0066] When the determination unit 14 determines that the first image should be enlarged, the control unit 15 enlarges the first image by increasing the cropping range for cropping the first image from the captured image of the rear side of the vehicle 1, and displays the enlarged first image on the display unit 2.

[0067] When the determination unit 14 has not determined that the first image should be enlarged, the first image is trimmed from the captured image in the normal trimming range and displayed on the display unit 2. The normal trimming range is determined based on the size of the display unit 2, etc. The normal trimming range may be determined in advance by the user or by the control unit 15. For example, when the first image is displayed on the display 2a, the normal trimming range is a range in which the first image is displayed on the entire display 2a. In this case, the first image trimmed from the captured image in the normal trimming range is displayed on the entire display 2a. Note that the normal trimming range when the first image is displayed on the display 2a may be a range that is displayed not on the entire display 2a but on a part of it. In this case, the first image trimmed from the captured image in the normal trimming range is displayed on a part of the display 2a.

[0068] When the determination unit 14 determines that the first image is to be enlarged, the control unit 15 enlarges the first image by making the trimming range larger than the normal trimming range. How to enlarge the trimming range is determined by the size of the captured image, the size of the display unit 2, the arrangement of the display unit 2, and the like. How to enlarge the trimming range may be determined in advance by the user or by the control unit 15. For example, when the first image is displayed on the display 2a, if there is a display adjacent to the display 2a in the left-right direction, the trimming range is determined to be as large as possible on the left side within the range of the captured image and within the range that can be displayed on the display unit 2. Also, when the first image is displayed on the display 2a, if there is a display adjacent to the display 2a in the up-down direction, the trimming range is determined to be as large as possible on the lower side within the range of the captured image and within the range that can be displayed on the display unit 2. Note that the trimming range may be enlarged by a predetermined amount rather than enlarging the trimming range as much as possible.

[0069] When determination unit 14 determines that the first image should be enlarged, control unit 15 generates an enlarged first image by cropping the first image from the captured image with a cropping range larger than a normal cropping range. Control unit 15 causes image output unit 16 to output the enlarged first image to display unit 2, and causes the first image to be displayed on display unit 2. The scale of the first image enlarged by control unit 15 and displayed on display unit 2 is the same as the scale of the first image that was displayed on display unit 2 before being enlarged by control unit 15.

[0070] The image output unit 16 outputs the first image and the like generated by the control unit 15 to the display unit 2.

[0071] Fig. 3 is a flowchart showing an example of a display control method by the display control device 10 in Fig. 1. Next, with reference to Fig. 3, an example of a display control method by the display control device 10 in Fig. 1 will be described.

[0072] 3, the running state determination unit 12 acquires vehicle information of the vehicle 1 (step S1), and determines the running state of the vehicle 1 based on the vehicle information (step S2). For example, the running state determination unit 12 determines the running state of the vehicle 1 as described above.

[0073] The acquisition unit 13 acquires the traveling state determined by the traveling state determination unit 12 (acquisition step) (step S3).

[0074] The determination unit 14 determines whether or not to enlarge the first image, which is a first image cropped from a captured image of the rear side of the vehicle 1 and is displayed on the display unit 2 arranged on the vehicle 1, based on the traveling state acquired by the acquisition unit 13 (determination step) (step S4). For example, as described above, the determination unit 14 determines whether or not to enlarge the first image displayed on the display unit 2 arranged on the vehicle 1.

[0075] If the determination unit 14 determines that the first image should not be enlarged (No in step S4), the control unit 15 displays the first image normally without enlarging the first image displayed on the display unit 2 (step S5). Displaying the first image normally means displaying the first image cropped from the captured image within the normal cropping range.

[0076] When the determination unit 14 determines that the first image is to be enlarged (Yes in step S4), the control unit 15 determines the trimming range (step S6). For example, as described above, the control unit 15 determines the trimming range and makes the trimming range larger than the normal trimming range.

[0077] The control unit 15 enlarges the first image by increasing the trimming range for trimming the first image from the captured image, and causes the display unit 2 to display the enlarged first image (control step) (step S7). For example, as described above, the control unit 15 causes the display unit 2 to display the enlarged first image.

[0078] The control unit 15 determines whether or not driving of the vehicle 1 has ended (step S8), and if it determines that driving of the vehicle 1 has not ended (No in step S8), it acquires vehicle information again (step S1), and if it determines that driving of the vehicle 1 has ended (Yes in step S8), it terminates the processing.

[0079] If judgment unit 14 determines that the first image should be enlarged (Yes in step S4) and control unit 15 displays the enlarged first image (step S7), and then if judgment unit 14 determines that the first image should not be enlarged (No in step S4), control unit 15 displays the first image normally by setting the cropping range to the normal cropping range (step S5).

[0080] Figures 4 to 12 are explanatory diagrams for explaining first to ninth operation examples of the display control device 10 in Figure 1. Next, the first to ninth operation examples of the display control device 10 will be described with reference to Figures 4 to 12.

[0081] 4 to 9, when the display unit 2 is arranged in the vehicle 1, the display control device 10 performs any one of the first to sixth operation examples. Which of the first to sixth operation examples is to be performed may be determined in advance by a user or the like, or may be determined by the display control device 10 based on the type of the image 21 or the like.

[0082] Furthermore, as shown in Fig. 10, when the display unit 42 is arranged in the vehicle 1, the display control device 10 performs a seventh operation example. As shown in Fig. 11, when the display unit 52 is arranged in the vehicle 1, the display control device 10 performs an eighth operation example. As shown in Fig. 12, when the display unit 62 is arranged in the vehicle 1, the display control device 10 performs a ninth operation example.

[0083] Fig. 4(a) shows a state before the image 20 is enlarged (normal display), and Fig. 4(b) shows a state after the image 20 is enlarged. First, a first operation example of the display control device 10 will be described with reference to Fig. 4.

[0084] As shown in (a) of Fig. 4, an image 20 that has been cropped from an image taken of the rear side of the vehicle 1 is displayed on the display unit 2. Here, the image 20 is an image that has been cropped from an image taken of the left rear of the vehicle 1, and is displayed on the display 2a. The image 20 is displayed over the entirety of the display 2a.

[0085] Also, an image 21 is displayed on the display unit 2. Here, the image 21 is not an image cropped from a captured image of the rear side of the vehicle 1, but is displayed on the display 2b. The image 21 includes a plurality of images 22, 23, and 24. The plurality of images 22, 23, and 24 are arranged side by side in the left-right direction. The image 21 is displayed over the entirety of the display 2b.

[0086] Also, an image 25 cropped from an image taken of the rear side of the vehicle 1 is displayed on the display unit 2. Here, the image 25 is an image cropped from an image taken of the right rear side of the vehicle 1, and is displayed on the display 2c. The image 25 is displayed over the entirety of the display 2c.

[0087] The determination unit 14 determines whether or not to enlarge the image 20 displayed on the display unit 2 arranged on the vehicle 1, which is a cropped image of the rear side of the vehicle 1, based on the traveling state acquired by the acquisition unit 13 (step S4 in FIG. 3). Here, when the vehicle 1 is in a state of moving to the left, the determination unit 14 determines that the image 20 displayed on the display 2a should be enlarged (Yes in step S4 in FIG. 3).

[0088] As shown in (b) of Fig. 4, when the determination unit 14 determines that the image 20 should be enlarged, the control unit 15 enlarges the image 20 by enlarging the cropping range for cropping the image 20 from the captured image, and causes the display unit 2 to display the enlarged image 20 (step S7 of Fig. 3). Here, the control unit 15 enlarges the image 20 by enlarging the cropping range on the left side, and causes the enlarged image 20 to be displayed on the display 2a and also on the display 2b, so that the enlarged image 20 is displayed across the display 2a and the display 2b. This makes it possible to view the image 20 further to the left than before it was enlarged.

[0089] Here, when the enlarged image 20 is displayed across the displays 2a and 2b, the control unit 15 reduces the size of the image 21 by reducing the entire image 21 in the left-right direction, and displays the reduced image 21 in an area of ​​the display 2b where the image 20 is not displayed. As a result, each of the multiple images 22, 23, and 24 is reduced in the left-right direction.

[0090] Although not shown, the determination unit 14 determines whether or not to enlarge the image 25 displayed on the display unit 2 arranged on the vehicle 1, which is a cropped image of the rear side of the vehicle 1, based on the traveling state acquired by the acquisition unit 13 (step S4 in FIG. 3). Here, when the vehicle 1 is in a state of moving to the right, the determination unit 14 determines that the image 25 displayed on the display 2c should be enlarged (Yes in step S4 in FIG. 3).

[0091] When the determination unit 14 determines that the image 25 should be enlarged, the control unit 15 enlarges the image 25 by enlarging the cropping range for cropping the image 25 from the captured image, and causes the display unit 2 to display the enlarged image 25 (step S7 in FIG. 3). Here, the control unit 15 enlarges the image 25 by enlarging the cropping range on the right side, and causes the enlarged image 25 to be displayed on the display 2c as well as on the display 2b, so that the enlarged image 25 is displayed across the display 2c and the display 2b. This allows the image 20 to be viewed further to the right than before it was enlarged.

[0092] Here, when the enlarged image 25 is displayed across the displays 2c and 2b, the control unit 15 reduces the size of the image 21 by reducing the entire image 21 in the left-right direction, and displays the reduced image 21 in an area of ​​the display 2b where the image 25 is not displayed. As a result, each of the multiple images 22, 23, and 24 is reduced in the left-right direction.

[0093] In this way, the display control device 10 performs the same process on the image 25 as on the image 20. The same applies to the second to sixth operation examples shown in Figs.

[0094] The display control device 10 of this embodiment includes an acquisition unit 13 that acquires the driving condition of the vehicle 1, a judgment unit 14 that judges whether or not to enlarge the image 20 (or image 25) (first image) that is cropped from a captured image of the rear side of the vehicle 1 and displayed on a display unit 2 arranged on the vehicle 1 based on the driving condition acquired by the acquisition unit 13, and a control unit 15 that, when the judgment unit 14 judges that the image 20 (or image 25) should be enlarged, enlarges the image 20 (or image 25) by increasing the cropping range for cropping the image 20 (or image 25) from the captured image, and displays the enlarged image 20 (or image 25) on the display unit 2.

[0095] According to this, the image 20 (or image 25) can be enlarged by increasing the cropping range for cropping the image 20 (or image 25) from the captured image of the rear side of the vehicle 1, and the enlarged image 20 (or image 25) can be displayed on the display unit 2. Therefore, the rear side of the vehicle 1 can be visually recognized over a wider range, making it easier to check the rear side of the vehicle 1.

[0096] Moreover, in the display control device 10 of this embodiment, the captured image is an image captured of the left (or right) rear of the vehicle 1 in the left-right direction, the display unit 2 has a display 2a (or display 2c) (first display) that is located forward of the driver's seat of the vehicle 1 in the fore-and-aft direction of the vehicle 1 and to the left (or right) of the center in the left-right direction and displays an image so that it can be seen from the driver's seat, and when the vehicle 1 is in a state in which it is about to move to the left (or right), the determination unit 14 determines that the image 20 (or image 25) displayed on the display 2a (or display 2c) should be enlarged, and when the determination unit 14 determines that the image 20 (or image 25) should be enlarged, the control unit 15 enlarges the image 20 (or image 25) by increasing the trimming range and displays the enlarged image 20 (or image 25) on the display 2a (or display 2c).

[0097] According to this, when the vehicle 1 is about to move to the left (or right), the enlarged image 20 (or image 25) can be displayed on the display 2a (or display 2c). Therefore, when the vehicle 1 is about to move to the left (or right), the left (or right) rear of the vehicle 1 can be easily viewed over a wider range, making it even easier to check the rear side of the vehicle 1.

[0098] Moreover, in the display control device 10 of this embodiment, the display unit 2 has a display 2b (second display) that is located to the right (or left) of the display 2a (or display 2c) in the left-right direction, is located in the center, and displays an image so that it can be seen from the driver's seat, and when the vehicle 1 is in a state in which it is about to move to the left (or right), the judgment unit 14 judges that the image 20 (or image 25) displayed on the display 2a (or display 2c) should be enlarged, and when the judgment unit 14 judges that the image 20 (or image 25) should be enlarged, the control unit 15 enlarges the image 20 (or image 25) by increasing the trimming range to the left (or right) and displays the enlarged image 20 (or image 25) across the display 2a (or display 2c) and display 2b.

[0099] According to this, when the vehicle 1 is about to move to the left (or right), the enlarged image 20 (or image 25) can be displayed across the display 2a (or display 2c) and the display 2b. Therefore, when the vehicle 1 is about to move to the left (or right), the left (or right) rear of the vehicle 1 can be more easily viewed over a wider range, making it easier to check the rear side of the vehicle 1.

[0100] Furthermore, in the display control device 10 of this embodiment, when the control unit 15 displays the enlarged image 20 (or image 25) across the display 2a (or display 2c) and the display 2b, if image 21 (second image) is displayed on the display 2b, the control unit 15 reduces the size of the image 21 by shrinking the entire image 21 in the left-right direction, and displays the reduced image 21 in an area of ​​the display 2b where the image 20 (or image 25) is not displayed.

[0101] According to this, the image 21 can be displayed together with the enlarged image 20 (or image 25) without deleting the image 21. Therefore, it is possible to prevent a decrease in the amount of information obtained by the image 21, and it is possible to make it easier to check the rear side of the vehicle 1.

[0102] Furthermore, the display control method according to this embodiment includes an acquisition step (step S1) for acquiring the driving condition of the vehicle 1, a determination step (step S4) for determining whether or not to enlarge the image 20 (or image 25), which is cropped from a captured image of the rear side of the vehicle 1 and is displayed on a display unit 2 arranged on the vehicle 1, based on the driving condition acquired by the acquisition step, and a control step (step S7) for enlarging the image 20 (or image 25) by increasing the cropping range for cropping the image 20 (or image 25) from the captured image, and displaying the enlarged image 20 (or image 25) on the display unit 2, if it is determined by the determination step that the image 20 (or image 25) should be enlarged.

[0103] This provides the same operational effects as the display control device 10 described above.

[0104] Moreover, a program according to the present embodiment is a program for causing a computer to execute the above-described display control method.

[0105] This provides the same operational effects as the display control device 10 described above.

[0106] Fig. 5(a) shows a state before the image 20 is enlarged (normal display), and Fig. 5(b) shows a state after the image 20 is enlarged. Next, a second operation example of the display control device 10 will be described with reference to Fig. 5.

[0107] The second operation example differs from the first operation example mainly in the following points.

[0108] 5(b), when the control unit 15 displays the enlarged image 20 across the displays 2a and 2b, the control unit 15 reduces the size of the image 21 by reducing a part of the image 21 in the left-right direction, and displays the reduced image 21 in an area of ​​the display 2b where the image 20 is not displayed. Here, the control unit 15 reduces the image 22 and the image 23, which have low priorities among the multiple images 22, 23, and 24, in the left-right direction. For example, the priorities are determined in advance by a user or the like.

[0109] Although not shown in the figure, the same applies to the case where an enlarged image 25 is displayed across the displays 2c and 2b.

[0110] In the display control device 10 of this embodiment, when the control unit 15 displays an enlarged image 20 (or image 25) across display 2a (or display 2c) and display 2b, if image 21 (second image) is displayed on display 2b, the control unit 15 reduces the size of image 21 by shrinking a part of image 21 in the left-right direction, and displays the reduced image 21 in an area of ​​display 2b where image 20 (or image 25) is not displayed.

[0111] According to this, the image 21 can be displayed together with the enlarged image 20 (or image 25) without deleting the image 21. Therefore, it is possible to prevent a decrease in the amount of information obtained by the image 21, and it is possible to make it easier to check the rear side of the vehicle 1.

[0112] Fig. 6(a) shows a state before the image 20 is enlarged (normal display), and Fig. 6(b) shows a state after the image 20 is enlarged. Next, a third operation example of the display control device 10 will be described with reference to Fig. 6.

[0113] The third operation example differs from the first operation example mainly in the following points.

[0114] As shown in (b) of FIG. 6, when the control unit 15 displays the enlarged image 20 across the display 2a and the display 2b, the control unit 15 reduces the size of the image 21 by deleting a part of the image 21 from the display 2b, and displays the reduced image 21 in an area of ​​the display 2b where the image 20 is not displayed. Here, the control unit 15 deletes the image 22, which has the lowest priority among the multiple images 22, 23, and 24. For example, the priority is determined in advance by a user or the like. In addition, the control unit 15 enlarges the image 23 in the left-right direction, so that the image 21 is displayed in the entire area of ​​the display 2b where the image 20 is not displayed.

[0115] Although not shown in the figure, the same applies to the case where an enlarged image 25 is displayed across the displays 2c and 2b.

[0116] In the display control device 10 of this embodiment, when the control unit 15 displays an enlarged image 20 (or image 25) across display 2a (or display 2c) and display 2b, if image 21 is displayed on display 2b, the control unit 15 reduces the size of image 21 by deleting part of image 21 from display 2b, and displays the reduced image 21 in an area of ​​display 2b where image 20 (or image 25) is not displayed.

[0117] This allows the image 21 to be displayed together with the enlarged image 20 (or image 25) without reducing the scale of the portion of the image 21 that is not deleted. Therefore, the portion of the image 21 that is not deleted can be easily visually recognized, and the rear side of the vehicle 1 can be easily confirmed.

[0118] Fig. 7(a) shows a state before the image 20 is enlarged (normal display), and Fig. 7(b) shows a state after the image 20 is enlarged. Next, a fourth operation example of the display control device 10 will be described with reference to Fig. 7.

[0119] The fourth operation example differs from the first operation example mainly in the following points.

[0120] As shown in FIG. 7B, when the control unit 15 displays the enlarged image 20 across the display 2a and the display 2b, the control unit 15 reduces each of the multiple images 22 and 23 in the vertical direction of the vehicle 1 and arranges the multiple images 22 and 23 in the vertical direction to reduce the image 21, and displays the reduced image 21 in an area of ​​the display 2b where the image 20 is not displayed. Here, the control unit 15 reduces the images 22 and 23, which have low priorities among the multiple images 22, 23, and 24, in the vertical direction and arranges them in the vertical direction. For example, the priority is determined in advance by a user or the like. In addition, the control unit 15 enlarges the images 22 and 23, which have been reduced in the vertical direction, in the horizontal direction, so that the image 21 is displayed in the entire area of ​​the display 2b where the image 20 is not displayed.

[0121] Although not shown in the figure, the same applies to the case where an enlarged image 25 is displayed across the displays 2c and 2b.

[0122] In the display control device 10 of this embodiment, when an enlarged image 20 (or image 25) is displayed across display 2a (or display 2c) and display 2b, if image 21 including multiple images 22, 23 arranged in the left-right direction is displayed on display 2b, the control unit 15 reduces each of the multiple images 22, 23 in the vertical direction of vehicle 1 and arranges the multiple images 22, 23 in a vertical direction to reduce the size of image 21, and displays the reduced image 21 in an area of ​​display 2b where image 20 (or image 25) is not displayed.

[0123] According to this, the image 21 can be displayed together with the enlarged image 20 (or image 25) without deleting the image 21. Therefore, it is possible to prevent a decrease in the amount of information obtained by the image 21, and it is possible to make it easier to check the rear side of the vehicle 1.

[0124] Fig. 8(a) shows a state before the image 20 is enlarged (normal display), and Fig. 8(b) shows a state after the image 20 is enlarged. Next, a fifth operation example of the display control device 10 will be described with reference to Fig. 8.

[0125] The fifth operation example differs from the first operation example mainly in the following points.

[0126] 8(b), when the control unit 15 displays the enlarged image 20 across the displays 2a and 2b, the control unit 15 displays the portion of the enlarged image 20 that is displayed on the display 2b by superimposing it on the image 21. Here, the control unit 15 displays the portion of the enlarged image 20 that is displayed on the display 2b by superimposing it on the image 22. As a result, a part of the image 22 is hidden by the image 20.

[0127] Although not shown in the figure, the same applies to the case where an enlarged image 25 is displayed across the displays 2c and 2b.

[0128] In the display control device 10 of this embodiment, when an enlarged image 20 (or image 25) is displayed across display 2a (or display 2c) and display 2b, if image 21 is displayed on display 2b, the control unit 15 displays the portion of the enlarged image 20 (or image 25) that is displayed on display 2b by superimposing it on image 21.

[0129] This allows image 21 to be displayed together with enlarged image 20 (or image 25) without reducing the scale of the portion of image 21 that is not superimposed on image 20 (or image 25). Therefore, the portion of image 21 that is not superimposed on image 20 (or image 25) can be easily viewed, and the rear side of vehicle 1 can be easily confirmed.

[0130] Fig. 9(a) shows a state before the image 20 is enlarged (normal display), and Fig. 9(b) shows a state after the image 20 is enlarged. Next, a sixth operation example of the display control device 10 will be described with reference to Fig. 9.

[0131] The sixth operation example differs from the first operation example mainly in the following points.

[0132] As shown in (b) of FIG. 9, when the control unit 15 displays the enlarged image 20 across the displays 2a and 2b, the control unit 15 displays the image 21 across the area of ​​the display 2b where the image 20 is not displayed and the display 2c. The control unit 15 also reduces the size of the image 25 by deleting a part of the image 25 from the display 2c, and displays the reduced image 25 in the area of ​​the display 2c where the image 21 is not displayed. Here, the control unit 15 moves the right end of the trimming range for trimming the image 25 from the captured image to the left, thereby reducing the trimming range, thereby deleting a part of the image 25 from the display 2c. The image 25 is displayed in the entire area of ​​the display 2c where the image 21 is not displayed.

[0133] Although not shown in the figure, the same applies to the case where an enlarged image 25 is displayed across the displays 2c and 2b.

[0134] In the display control device 10 according to this embodiment, the display unit 2 has a display 2c (or display 2a) (third display) that is located to the right (or left) of the display 2b in the left-right direction and displays an image so that it can be viewed from the driver's seat, and when the control unit 15 displays the enlarged image 20 (or image 25) across the display 2a (or display 2c) and the display 2b, if the image 21 is displayed on the display 2b and the image 25 (or image 20) (third image) is displayed on the display 2c (or display 2a), the control unit 15 displays the image 21 across an area of ​​the display 2b where the image 20 (or image 25) is not displayed and the display 2c (or display 2a), reduces the size of the image 25 (or image 20) by deleting a part of the image 25 (or image 20) from the display 2c (or display 2a), and displays the reduced image 25 (or image 20) in the area of ​​the display 2c (or display 2a) where the image 21 is not displayed.

[0135] This allows image 21 and image 25 (or image 20) to be displayed together with enlarged image 20 (or image 25) without deleting image 21 and without reducing the scale of the portion of image 25 (or image 20) that is not deleted. This makes it possible to prevent a decrease in the amount of information obtained from image 21, and also makes it easy to visually confirm the portion of image 25 (or image 20) that is not deleted, and to easily check the rear side of vehicle 1.

[0136] Fig. 10(a) shows a state before the image 20 is enlarged (normal display), and Fig. 10(b) shows a state after the image 20 is enlarged. Next, a seventh operation example of the display control device 10 will be described with reference to Fig. 10.

[0137] Here, a display unit 42 is provided in place of the display unit 2 in the vehicle 1. The display unit 42 differs from the display unit 2 mainly in the following points.

[0138] As shown in FIG. 10(a), the display unit 42 has a display 2d that is located to the left of the display 2a in the left-right direction and displays an image so as to be visible from the driver's seat of the vehicle 1. The display unit 42 also has a display 2e that is located to the right of the display 2c in the left-right direction and displays an image so as to be visible from the driver's seat of the vehicle 1. The display surface that displays the image in the display 2d faces the driver's seat side of the vehicle 1. The display surface that displays the image in the display 2e faces the driver's seat side of the vehicle 1. The right end of the display 2d is adjacent to the left end of the display 2a. The left end of the display 2e is adjacent to the right end of the display 2c. The display 2d is physically separate from the display 2a, and the display 2e is physically separate from the display 2c.

[0139] The seventh operation example differs from the first operation example mainly in the following points.

[0140] As shown in (b) of Figure 10, when the judgment unit 14 judges that the image 20 should be enlarged, the control unit 15 enlarges the image 20 by increasing the trimming range on the left side, and displays the enlarged image 20 on both display 2a and display 2d, thereby displaying the enlarged image 20 across display 2a and display 2d.

[0141] Although not shown in the figure, when the judgment unit 14 judges that the image 25 should be enlarged, the control unit 15 enlarges the image 25 by increasing the cropping range on the right side, and displays the enlarged image 25 on the display 2c as well as the display 2e, so that the enlarged image 25 is displayed across the display 2c and the display 2e.

[0142] In the display control device 10 of this embodiment, the display unit 42 has a display 2d (or display 2e) (fourth display) that is located to the left (or right) of the display 2a (or display 2c) in the left-right direction and displays an image so that it can be seen from the driver's seat, and when the vehicle 1 is in a state in which it is about to move to the left (or right), the judgment unit 14 judges that the image 20 (or image 25) displayed on the display 2a (or display 2c) should be enlarged, and when the judgment unit 14 judges that the image 20 (or image 25) should be enlarged, the control unit 15 enlarges the image 20 (or image 25) by increasing the trimming range to the left (or right) and displays the enlarged image 20 (or image 25) across the display 2a (or display 2c) and the display 2d (or display 2e).

[0143] According to this, when the vehicle 1 is about to move to the left (or right), the enlarged image 20 (or image 25) can be displayed across the display 2a (or display 2c) and the display 2d (or display 2e). Therefore, when the vehicle 1 is about to move to the left (or right), the left (or right) rear of the vehicle 1 can be more easily viewed over a wider range, making it easier to check the rear side of the vehicle 1.

[0144] Fig. 11(a) shows a state (normal display) before the image 20 and the image 25 are enlarged, and Fig. 11(b) shows a state after the image 20 and the image 25 are enlarged. Next, an eighth operation example of the display control device 10 will be described with reference to Fig. 11.

[0145] Here, a display unit 52 is provided in place of the display unit 2 in the vehicle 1. The display unit 52 differs from the display unit 2 mainly in the following points.

[0146] As shown in FIG. 11(a), the display unit 52 has a display 2f that is located below the display 2a in the vertical direction and displays an image so that it can be viewed from the driver's seat. The display unit 52 also has a display 2g that is located below the display 2c in the vertical direction and displays an image so that it can be viewed from the driver's seat. The display surface that displays the image in the display 2f faces the driver's seat side of the vehicle 1. The display surface that displays the image in the display 2g faces the driver's seat side of the vehicle 1. The upper end of the display 2f is adjacent to the lower end of the display 2a. The upper end of the display 2g is adjacent to the lower end of the display 2c. The display 2f is physically separate from the display 2a, and the display 2g is physically separate from the display 2c.

[0147] The eighth operation example differs from the first operation example mainly in the following points.

[0148] 11(a), when the vehicle 1 is about to move backward, the determination unit 14 determines that the image 20 displayed on the display 2a should be enlarged (Yes in step S4 in FIG. 3). Also, when the vehicle 1 is about to move backward, the determination unit 14 determines that the image 25 displayed on the display 2c should be enlarged (Yes in step S4 in FIG. 3).

[0149] As shown in (b) of Fig. 11, when the determination unit 14 determines that the image 20 should be enlarged, the control unit 15 enlarges the image 20 by enlarging the cropping range, and displays the enlarged image 20 on the display 2a (step S7 of Fig. 3). Here, the control unit 15 enlarges the image 20 by enlarging the cropping range downward, and displays the enlarged image 20 on the display 2a and also on the display 2f, so that the enlarged image 20 is displayed across the displays 2a and 2f. As a result, the lower left side can be viewed further than before the image 20 was enlarged, making it easier to view white lines drawn on the ground, etc.

[0150] Furthermore, when the determination unit 14 determines that the image 25 should be enlarged, the control unit 15 enlarges the image 25 by enlarging the cropping range, and causes the enlarged image 25 to be displayed on the display 2c (step S7 in FIG. 3). Here, the control unit 15 enlarges the image 25 by enlarging the cropping range downward, and causes the enlarged image 25 to be displayed on the display 2c and also on the display 2g, so that the enlarged image 25 is displayed across the displays 2c and 2g. This makes it possible to view the lower right side further than before the image 20 was enlarged, making it easier to view white lines drawn on the ground, etc.

[0151] In addition, when a display unit 52 is installed in a vehicle 1, the display control device 10 may perform any one of the first to sixth operation examples when the vehicle 1 is about to move to the left or right.

[0152] In the display control device 10 of this embodiment, the captured image is an image captured of the left (or right) rear of the vehicle 1 in the left-right direction, the display unit 2 has a display 2a (or display 2c) (first display) that is located forward of the driver's seat of the vehicle 1 in the fore-and-aft direction of the vehicle 1 and to the left (or right) of the center in the left-right direction and displays an image so that it can be seen from the driver's seat, and when the vehicle 1 is in a state where it is about to reverse, the judgment unit 14 judges that the image 20 (or image 25) displayed on the display 2a (or display 2c) should be enlarged, and when the judgment unit 14 judges that the image 20 (or image 25) should be enlarged, the control unit 15 enlarges the image 20 (or image 25) by increasing the trimming range and displays the enlarged image 20 (or image 25) on the display 2a (or display 2c).

[0153] According to this, when the vehicle 1 is about to move backward, the enlarged image 20 (or image 25) can be displayed on the display 2a (or display 2c). Therefore, when the vehicle 1 is about to move left (or right), the left (or right) rear of the vehicle 1 can be easily viewed over a wider range, making it even easier to check the rear side of the vehicle 1.

[0154] Furthermore, in the display control device 10 of this embodiment, the display unit 52 has a display 2f (or display 2g) (fifth display) that is located below the display 2a (or display 2c) in the vertical direction of the vehicle 1 and displays an image so that it can be seen from the driver's seat, and when the vehicle 1 is in a state where it is about to back up, the judgment unit 14 judges that the image 20 (or image 25) displayed on the display 2a (or display 2c) should be enlarged, and when the judgment unit 14 judges that the image 20 (or image 25) should be enlarged, the control unit 15 enlarges the image 20 (or image 25) by increasing the trimming range downward and displays the enlarged image 20 (or image 25) across both the display 2a (or display 2c) and the display 2f (or display 2g).

[0155] According to this, when the vehicle 1 is about to reverse, the enlarged image 20 (or image 25) can be displayed across the display 2a (or display 2c) and the display 2f (or display 2g). Therefore, when the vehicle 1 is about to reverse, the left (or right) rear of the vehicle 1 can be more easily viewed over a wider range, making it easier to check the rear side of the vehicle 1.

[0156] Fig. 12(a) shows the display 2h, and Fig. 12(b) shows the displays 2a, 2b, and 2c. Next, a ninth operation example of the display control device 10 will be described with reference to Fig. 12.

[0157] Here, a display unit 62 is disposed in the vehicle 1 instead of the display unit 2. The display unit 62 differs from the display unit 2 mainly in the following points.

[0158] 12, the display unit 62 has a display 2h that is located forward of the driver's seat of the vehicle 1 in the front-rear direction, in the center of the vehicle 1 in the left-right direction, and above the display 2b in the up-down direction of the vehicle 1, and is smaller than the display 2b and displays an image so as to be visible from the driver's seat. The display surface of the display 2h that displays the image faces the driver's seat of the vehicle 1. For example, the display 2h is an electronic rearview mirror.

[0159] The ninth operation example differs from the first operation example mainly in the following points.

[0160] When the vehicle 1 is about to move backward, the determination unit 14 determines that the image 26 displayed on the display 2h should be enlarged (Yes in step S4 in FIG. 3). Here, the captured image is an image of the rear of the vehicle 1, and the image 26 is an image that has been cropped from the captured image.

[0161] When the determination unit 14 determines that the image 26 should be enlarged, the control unit 15 enlarges the image 26 by enlarging the trimming range, and causes the enlarged image 26 to be displayed on the display 2b (step S7 in FIG. 3). For example, the control unit 15 enlarges the image 26 by enlarging the trimming range on the left, right, and lower sides. This allows the left, right, and lower sides of the image 26 to be viewed further in comparison with before the image 26 was enlarged.

[0162] In addition, when a display unit 62 is installed in a vehicle 1, the display control device 10 may perform any one of the first to sixth operation examples when the vehicle 1 is about to move to the left or right.

[0163] In the display control device 10 of this embodiment, the captured image is an image captured behind the vehicle 1, and the display unit 62 has a display 2b (sixth display) that is located forward of the driver's seat of the vehicle 1 in the fore-and-aft direction of the vehicle 1, located in the center of the vehicle 1 in the left-right direction, and displays an image so that it can be seen from the driver's seat, and a display 2h (seventh display) that is located forward of the driver's seat in the fore-and-aft direction, located in the center, located higher than display 2b in the up-and-down direction of the vehicle, smaller than display 2b, and displays an image so that it can be seen from the driver's seat, and when the vehicle 1 is in a state where it is about to reverse, the determination unit 14 determines that the image 26 (first image) displayed on the display 2h should be enlarged, and when the determination unit 14 determines that the image 26 should be enlarged, the control unit 15 enlarges the image 26 by increasing the trimming range and displays the enlarged image 26 on the display 2b.

[0164] According to this, when the vehicle 1 is about to reverse, the enlarged image 26 can be displayed on the display 2b. Therefore, when the vehicle 1 is about to reverse, the rear of the vehicle 1 can be easily viewed over a wider range, making it even easier to check the rear side of the vehicle 1.
