Apparatus to adjust a field of view displayed on an electronic mirror using an automobile state or a driver action

1. An apparatus comprising:

an interface to a sensor, said sensor configured to generate a video signal having a first field of view based on a horizontal dimension and a vertical dimension corresponding to an aspect ratio of said sensor; and

a processor configured to (A) receive said video signal from said interface, (B) generate a second field of view from said video signal based on (i) said first field of view and (ii) a width and a height corresponding to an aspect ratio of a display and (C) present said second field of view to said display, wherein (a) said second field of view is a cropped version of said first field of view configured to show a first vertical portion of said vertical dimension that fits said height of said display, (b) said second field of view is generated by adjusting video data in said first field of view, (c) said aspect ratio of said sensor is different than said aspect ratio of said display and (d) cropping said first field of view in response to said difference between said aspect ratio of said sensor and said aspect ratio of said display enables said display to show said second field of view without distorting said video data.

2. The apparatus according to claim 1 , wherein said adjusting said video data in said first field of view comprises performing a digital movement of a capture window of said video data.

3. The apparatus according to claim 2 , wherein (i) said capture window is used to select said second field of view, (ii) said video data in said first field of view outside of said capture window comprises a second vertical portion that is a hidden portion captured by said sensor that does not fit said aspect ratio of said display and (iii) said hidden portion is cropped out of said second field of view.

4. The apparatus according to claim 2 , wherein said capture window has a shape conforming to said width and said height of said display.

5. The apparatus according to claim 4 , wherein (i) said width of said shape is larger than said height of said shape and (ii) said shape of said capture window comprises said first vertical portion of said vertical dimension and said horizontal dimension of said first field of view.

6. The apparatus according to claim 1 , wherein a second vertical portion of said first field of view is not in said second field of view in response to said difference between said aspect ratio of said display and said aspect ratio of said sensor.

7. The apparatus according to claim 6 , wherein said cropping removes said second vertical portion of said first field of view to generate said second field of view.

8. The apparatus according to claim 1 , wherein said second field of view is further based on an input.

9. The apparatus according to claim 8 , wherein said input comprises vehicle sensor information received from a vehicle.

10. The apparatus according to claim 9 , wherein said vehicle sensor information comprises a body position of a driver.

11. The apparatus according to claim 8 , wherein said input comprises a user input.

12. The apparatus according to claim 1 , wherein said display replaces a reflective rear-view mirror.

13. The apparatus according to claim 1 , wherein said first field of view comprises a view in a direction of a rear end of a vehicle.

14. The apparatus according to claim 1 , wherein said display emulates a reflective rear-view mirror.

15. The apparatus according to claim 1 , wherein said apparatus comprises a system on a chip (SoC).

16. The apparatus according to claim 1 wherein said display comprises an electronic mirror for a vehicle.

17. The apparatus according to claim 1 , wherein said apparatus is configured to adjust a field of view displayed on an electronic mirror using an automobile state.

18. The apparatus according to claim 1 , wherein said apparatus is configured to adjust a field of view displayed on an electronic mirror in response to a driver action.

19. An apparatus comprising:

a sensor configured to generate a video signal having a first field of view based on a horizontal dimension and a vertical dimension corresponding to an aspect ratio of said sensor; and

a processor configured to (A) receive said video signal, (B) generate a second field of view from said video signal based on (i) said first field of view and (ii) a width and a height corresponding to an aspect ratio of a display and (C) present said second field of view to said display, wherein (a) said second field of view is a cropped version of said first field of view configured to show a first vertical portion of said vertical dimension that fits said height of said display, (b) said second field of view is generated by adjusting video data in said first field of view, (c) said aspect ratio of said sensor is different than said aspect ratio of said display and (d) cropping said first field of view in response to said difference between said aspect ratio of said sensor and said aspect ratio of said display enables said display to show said second field of view without distorting said video data.

20. The apparatus according to claim 19 , wherein a second vertical portion of said first field of view is not in said second field of view in response to said difference between said aspect ratio of said display and said aspect ratio of said sensor.
