Abstract

A display screen of a display apparatus in an image display system includes a one-way mirror on a front side of the display screen. Moreover, an image obtaining part of a display control apparatus obtains a captured image captured by a camera that captures an image of surroundings of a vehicle. The image display system includes, as operation modes, an image display mode that displays the captured image on the display apparatus and a mirror mode that causes the display apparatus to be in a non-display state to cause the display screen of the display apparatus to function as a mirror. A determination part determines a state of the vehicle based on a signal relating to the vehicle and a mode setter sets the operation mode based on the state of the vehicle.

in a case where the state of the vehicle is determined to be the travelling state, the controller sets the operation mode to the first mode, and in a case where the state of the vehicle is determined to be the stopped state, the controller sets the operation mode to the second mode.

3. The display control apparatus according to claim 2, wherein

the signal relating to the vehicle is a signal indicative of a speed of the vehicle, and

the controller determines whether the state of the vehicle is the travelling state or the stopped state based on the signal indicative of the speed of the vehicle.

4. The display control apparatus according to claim 3, wherein

in a case where the speed of the vehicle is equal to or below a predetermined speed for a predetermined time period, the controller determines that the state of the vehicle is the stopped state.

5. The display control apparatus according to claim 3, wherein

in a case where the speed of the vehicle exceeds a predetermined speed for a predetermined time period, the controller determines that the state of the vehicle is the travelling state.

6. The display control apparatus according to claim 2, wherein

the signal relating to the vehicle is a signal indicative of a position of a gearshift of the vehicle, and

the controller determines whether the state of the vehicle is the travelling state or the stopped state based on the signal indicative of the position of the gearshift of the vehicle.

7. The display control apparatus according to claim 1, wherein

the signal relating to the vehicle is a signal indicative of a position of a gearshift of the vehicle, and

in a case where the position of the gearshift of the vehicle is a drive position, the controller determines whether the state of the vehicle is a travelling state or a stopped state, according to a speed of the vehicle, and in a case where the position of the gearshift of the vehicle is a reverse position, the controller determines, regardless of the speed of the vehicle, the state of the vehicle is a backward-moving state, and

in a case where the state of the vehicle is determined to be one of the travelling state and the backward-moving state, the controller sets the operation mode to the first mode, and in a case where the state of the vehicle is determined to be the stopped state, the controller sets the operation mode to the second mode.

8. An image display system of a vehicle, the image display system comprising:

a display apparatus having a display screen including a one-way mirror, the display apparatus is provided in a cabin of the vehicle; and

a display control apparatus that controls the display apparatus and includes a controller configured to;

obtain a captured image captured by a camera that captures an image of surroundings of the vehicle;

determine a state of the vehicle based on a signal relating to the vehicle, the signal obtained by the controller; and

set an operation mode of the display apparatus based on the determined state of the vehicle, wherein

the operation mode is one of a first mode that displays the captured image on the display apparatus and a second mode that causes the display apparatus to be in a non-display state so that the display screen of the display apparatus functions as a mirror.

9. The image display system according to claim 8, wherein

the controller determines whether the state of the vehicle is a travelling state or a stopped state based on the signal relating to the vehicle, and

in a case where the state of the vehicle is determined to be the travelling state, the controller sets the operation mode to the first mode, and in a case where the state of the vehicle is determined to be the stopped state, the controller sets the operation mode to the second mode.

10. The image display system according to claim 9, wherein

the signal relating to the vehicle is a signal indicative of a speed of the vehicle, and

the controller determines whether the state of the vehicle is the travelling state or the stopped state based on the signal indicative of the speed of the vehicle.

11. The image display system according to claim 10, wherein

in a case where the speed of the vehicle is equal to or below a predetermined speed for a predetermined time period, the controller determines that the state of the vehicle is the stopped state.

12. The image display system according to claim 10, wherein

in a case where the speed of the vehicle exceeds a predetermined speed for a predetermined time period, the controller determines that the state of the vehicle is the travelling state.

13. The image display system according to claim 9, wherein

the signal relating to the vehicle is a signal indicative of a position of a gearshift of the vehicle, and

the controller determines whether the state of the vehicle is the travelling state or the stopped state based on the signal indicative of the position of the gearshift of the vehicle.

14. A display control method of controlling a display apparatus having a display screen that includes a one-way mirror and that is mounted in a vehicle, the display control method comprising the steps of:

(a) obtaining, by a controller, a captured image captured by a camera that captures an image of surroundings of the vehicle;

(b) determining, by the controller, a state of the vehicle based on a signal relating to the vehicle obtained by the controller; and

(c) setting, by the controller, an operation mode of the display apparatus based on the state of the vehicle determined by the step (b), wherein

the operation mode is one of a first mode that displays the captured image on the display apparatus and a second mode that causes the display apparatus to be in a non-display state so that the display screen of the display apparatus functions as a mirror.

15. The display control method according to claim 14, wherein

the step (b) determines whether the state of the vehicle is a travelling state or a stopped state, and
