Abstract

Systems and methods for monitoring a position of a window. A window position monitoring system comprises a display screen, a camera configured to capture an image for display on the display screen, and a controller including a processor and a memory. The memory includes instructions that, when executed by the processor, cause the processor to: determine a position of the window; determine at least one of a camera setting of a camera and a display screen setting of the display screen based on the determined position of the window; capture, using the camera, at least one frame of a video of a real-world environment; and display, on the display screen, based on the at least one of the camera setting and the display screen setting, the at least one frame of the video of the real-world environment.

Claims (52)

1. A window position monitoring system for a vehicle, the window position monitoring system comprising:

a display screen;

a camera configured to capture an image for display on the display screen;

a window position sensor; and

a controller including a processor and a memory, the memory including instructions that, when executed by the processor, cause the processor to:

determine a change of a position of a window within a field of view of the camera;

determine a change in ambient light present proximal an aperture of the camera resulting from the change of the position of the window;

determine, using the window position sensor, the position of the window relative to one of the field of view of the camera, the aperture of the camera, a closed position of the window, an opened position of the window, or a door of the vehicle;

modify at least one of a camera setting of the camera and a display screen setting of the display screen based on the determined change of the position of the window and the determined change in the ambient light to account for an absence of the window from at least a portion of the field of view of the camera;

capture, using the camera, at least one frame of a video of a real-world environment; and

display, on the display screen, based on the at least one of the camera setting and the display screen setting, the at least one frame of the video of the real-world environment.

2. The window position monitoring system for the vehicle of claim 1 , further comprising a light sensor configured to determine an amount of ambient light present at the aperture of the camera.

3. The window position monitoring system for the vehicle of claim 1 , wherein the display screen includes a portion of a rear-view mirror.

4. The window position monitoring system for the vehicle of claim 1 , wherein the instructions further comprise instructions to cause the processor to:

display, on the display screen, a window position indicator based on the determined position of the window.

5. The window position monitoring system for the vehicle of claim 1 , wherein the camera is one of a rear-view camera, a side-view camera, and a dash camera.

6. The window position monitoring system for the vehicle of claim 1 , wherein the window is configured to move between a closed state and an opened state, wherein the window is positioned between the camera and the real-world environment in the closed state, and wherein the window is positioned such that at least a portion of the window is between the camera and the real-world environment or the camera has an unobstructed field of view of the real-world environment.

7. The window position monitoring system for the vehicle of claim 1 , wherein the window is transparent or at least partially translucent.

8. The window position monitoring system for the vehicle of claim 1 , wherein the camera setting includes at least one of a brightness setting, an exposure setting, a night setting, a day setting, a headlamp glare reduction setting, an LED headlamp flicker reduction setting, or a tinted window setting.

9. The window position monitoring system for the vehicle of claim 1 , wherein the display screen setting includes at least one of a brightness setting, a night setting, a day setting, a headlamp glare reduction setting, or an LED headlamp flicker reduction setting.

10. A method of monitoring a position of a window, the method comprising:

determining a change of the position of the window within a field of view of a camera, wherein determining the position of the window comprises determining, using a window position sensor, the position of the window relative to one of the field of view of the camera, an aperture of the camera, a closed position of the window, an opened position of the window, or a door of a vehicle;

determining a change in ambient light present proximal the aperture of the camera resulting from the change of the position of the window;

modifying at least one of a camera setting of the camera and a display screen setting of a display screen based on the determined change of the position of the window and the determined change in the ambient light to account for an absence of the window from at least a portion of the field of view of the camera;

capturing, using the camera, at least one frame of a video of a real-world environment; and

displaying, on the display screen, based on the at least one of the camera setting and the display screen setting, the at least one frame of the video of the real-world environment.

11. The method of monitoring the position of the window according to claim 10 , further comprising determining, using a light sensor, an amount of ambient light present at the camera.

12. The method of monitoring the position of the window according to claim 10 , wherein displaying, on the display screen comprises displaying the at least one frame of the video of the real-world environment on at least a portion of a rear-view mirror.

13. The method of monitoring the position of the window according to claim 10 , further comprising displaying, on the display screen, a window position indicator based on the determined position of the window.

14. The method of monitoring the position of the window according to claim 10 , wherein the camera is one of a rear-view camera, a side-view camera, and a dash camera.

15. The method of monitoring the position of the window according to claim 10 , wherein the window is configured to move between a closed state and an opened state, wherein the window is positioned between the camera and the real-world environment in the closed state, and wherein the window is positioned such that at least a portion of the window is between the camera and the real-world environment or the camera has an unobstructed field of view of the real-world environment.

16. The method of monitoring the position of the window according to claim 10 , wherein the window is transparent or at least partially translucent.

17. The method of monitoring the position of the window according to claim 10 , wherein the camera setting includes at least one of a brightness setting, an exposure setting, a night setting, a day setting, a headlamp glare reduction setting, an LED headlamp flicker reduction setting, or a tinted window setting.

18. The method of monitoring the position of the window according to claim 10 , wherein the display screen setting includes at least one of a brightness setting, a night setting, a day setting, a headlamp glare reduction setting, or an LED headlamp flicker reduction setting.

19. A non-transitory computer-readable medium having one or more instructions corresponding to a window position monitoring application that, when executed by a processor, cause the processor to:

determine a change of a position of a window within a field of view of a camera;

determine a change in ambient light present proximal an aperture of the camera resulting from the change of the position of the window;

determine, using a window position sensor, the position of the window relative to one of the field of view of the camera, the aperture of the camera, a closed position of the window, an opened position of the window, or a door of a vehicle;

modify at least one of a camera setting of the camera and a display screen setting of a display screen based on the determined change of the position of the window and the determined change in the ambient light to account for an absence of the window from at least a portion of the field of view of the camera;

capture, using the camera, at least one frame of a video of a real-world environment; and
