Abstract
An automobile includes a rearview mirror, a motor electrically coupled to the rearview mirror, an image capturing unit configured to capture a number of images of a face of a driver in real time, a light detecting unit configured to detect light on the rearview mirror, a storage unit configured to store a preset value of light intensity, and a processing unit configured to execute an automatic adjusting system to adjust a position of the rearview mirror when one of a number of conditions is met. The number of conditions include a position of eyes of the driver changes, and light exceeding the preset value of intensity enters into the eyes of the driver.

A method for automatically adjusting a rearview mirror of an automobile, the method comprising steps of:
- capturing, by an image capturing unit, a plurality of images of a driver's face in real time;
- detecting, by a light detecting unit, light on the rearview mirror;
- obtaining from each image, by a processing unit, a position of eyes of the driver;
- calculating from the light on the rearview mirror, by the processing unit, an incident angle of the light on the rearview mirror, an angle of reflection of the light from the rearview mirror, and an intensity of the light;
- comparing, by the processing unit, every two successive images of the driver's face, and determining whether the position of the eyes of the driver has changed;
- determining, by the processing unit, whether the intensity of the light is greater than a preset value;
- determining, by the processing unit and when the illuminance value of the light is greater than the preset value, and according to the angle of reflection of the light from the rearview mirror and the position of the eyes of the driver, whether the light reflected off of the rearview mirror enters into the eyes of the driver;
- and
- adjusting, by the processing unit, an angle of the rearview mirror when it is determined that either the position of the eyes of the driver has changed or that the light having an intensity greater than the preset value enters into the eyes of the driver;
- wherein a first signal corresponding to the plurality of images is generated by the image capturing unit, and a second signal corresponding to the light is generated by the light detecting unit;
- the position of the eyes of the driver is determined from the first signal;
- and the incident angle of the light on the rearview mirror, the angle of reflection of the light from the rearview mirror, and the intensity of the light are calculated from the second signal.
An automobile comprising:
- a rearview mirror;
- a motor electrically coupled to the rearview mirror and configured to adjust a position of the rearview mirror;
- an image capturing unit configured to capture a plurality of images of a face of a driver in real time;
- a light detecting unit configured to detect light on the rearview mirror;
- a storage unit configured to store a preset value of light intensity, and further store a plurality of instructions of a plurality of modules of an automatic adjusting system;
- and
- a processing unit configured to execute the plurality of instructions of the plurality of modules of the automatic adjusting system to adjust a position of the rearview mirror when one of a plurality of conditions is met,
- wherein the plurality of conditions for adjusting the position of the rearview mirror comprises:
- a position of eyes of the driver changes;
- and the light exceeding the preset value of light intensity enters into the eyes of the driver;
- the image capturing unit produces a first signal corresponding to the plurality of images of the driver's face;
- the light detecting unit produces a second signal corresponding to the light on the rearview mirror;
- the processing unit determines from the first signal whether the position of the eyes of the driver changes;
- and the processing unit determines from the second signal an incident angle of the light on the rearview mirror, an angle of reflection of the light from the rearview mirror, and an intensity of the light.
A method for automatically adjusting a rearview mirror of an automobile, the method comprising steps of:
- monitoring a driver's face in real time for changes in a position of eyes of the driver;
- determining an incident angle of light on the rearview mirror, an angle of reflection of the light from the rearview mirror, and whether the light reflected off of the rearview mirror enters into the eyes of the driver;
- determining whether an intensity of the light on the rearview mirror is above a preset value;
- and
- adjusting a position of the rearview mirror in response to either the position of the eyes changing or the light having a light intensity higher than the preset value reflects off the rearview mirror into the eyes of the driver.
