1. An apparatus comprising: (8) (2)

a sensor configured to generate a video signal comprising a plurality of frames based on a targeted view of a driver; and

a processor configured to generate a control signal in response to a determined field of view of said driver, wherein (A) said control signal is used to adjust one or more mirrors of a vehicle, (B) said field of view is determined based on location coordinates for eyes of said driver, (C) said location coordinates for said eyes are determined based on analysis of one or more video frames of said video signal to determine a depth coordinate representing a distance of said eyes from said sensor, and (D) said depth coordinate is determined based on a comparison of a reference number of pixels of an object in a reference video frame to a current number of pixels of said object in said video frames.

2. The apparatus according to claim 1, wherein said sensor is implemented as one of (i) a component of a camera and (ii) a video capturing device. (0)

3. The apparatus according to claim 1, wherein said reference number of pixels for said object is based on an object of known size. (1) (0)

5. The apparatus according to claim 1, wherein said control signal is configured to generate a warning. (0)

6. The apparatus according to claim 1, wherein said sensor is configured to implement a depth sensing camera system for determining said depth coordinate. (0)

7. The apparatus according to claim 1, wherein said (i) adjustment of said mirrors is performed automatically and (ii) manual controls for said mirrors are available for manual adjustment of said mirrors. (0)

8. The apparatus according to claim 1, wherein said determined field of view of said driver comprises a number of fields of view, each corresponding to one of said mirrors of said vehicle. (1) (0)

10. The apparatus according to claim 1, further comprising a second processor configured to (i) receive a bitstream generated by said sensor and (ii) transform said bitstream into said video signal of said driver. (0)

11. The apparatus according to claim 1, wherein said video signal comprises a plurality of digital images. (0)

12. An apparatus comprising: (1) (3)

a sensor configured to generate a bitstream based on a targeted view implemented by a video capture device, wherein said targeted view is selected to capture a driver of a vehicle;

a first processor configured to (i) receive said bitstream from said sensor and (ii) generate a video signal comprising a plurality of frames based on said bitstream; and

a second processor configured to generate a control signal in response to a determined field of view of said driver, wherein (A) said control signal is used to adjust one or more mirrors of said vehicle, (B) said field of view is determined based on location coordinates for eyes of said driver, (C) said location coordinates for said eyes are determined based on analysis of one or more video frames of said video signal to determine a depth coordinate representing a distance of said eyes from said sensor, and (D) said depth coordinate is determined based on a comparison of a reference number of pixels of an object in a reference video frame to a current number of pixels of said object in said video frames.

13. The apparatus according to claim 12, wherein said analysis of said video frames from said video signal is performed by (i) said first processor in a first mode and (ii) said second processor in a second mode. (0)

14. A method for adjusting mirrors of a vehicle, comprising the steps of: (4) (5)

(A) generating a video signal comprising a plurality of frames based on a targeted view of a driver;

(B) performing analysis of video frames of said video signal;

(D) calculating a field of view of said driver based on said location coordinates determined for said eyes of said driver; and

(E) generating a control signal in response to said calculated field of view of said driver, wherein (i) said control signal is used to adjust one or more of said mirrors of said vehicle, (ii) a depth coordinate representing a distance of said eyes from a sensor is used to determine said location coordinates for said eyes of said driver and (iii) said depth coordinate is determined based on a comparison of a reference number of pixels of an object in a reference video frame to a current number of pixels of said object in said video frames.

15. The method according to claim 14, wherein said sensor is implemented as one of (i) a component of a camera and (ii) a video capturing device. (0)

16. The method according to claim 14, wherein said reference number of pixels for said object is based on an object of known size. (1) (0)

18. The method according to claim 14, wherein said calculated field of view of said driver comprises a number of fields of view, each corresponding to one of said mirrors of said vehicle. (1) (0)

20. The method according to claim 14, wherein said video signal comprises a plurality of digital images. (0)
