Abstract

An apparatus is provided that includes at least one image sensor, and at least one processor. The processor is configured to receive at least a portion of at least one image from the at least one image sensor, wherein an aim of the at least one image sensor is a function of the at least one image. The processor is further configured to generate at least one vehicle equipment control signal as a function of at least one feature extracted from at least a portion of at least one image.

Claims (11)

1. An apparatus, comprising:

at least one image sensor; and at least one processor configured to receive at least a portion of at least one image from said at least a portion of at least one image sensor, said processor is configured to compute an average of at least one row of said at least a portion of at least one image, assign the average value to any pixel values below said average, take a first derivative of modified pixel data, threshold the modified pixel data via a histogram analysis and then take a second derivative of threshold modified pixel data.

2. An apparatus as in claim 1 configured as a rearview mirror assembly comprising a stationary housing, said stationary housing comprising at least one device selected from the group comprising: an imager, an automatic exterior light control module, a moisture sensor module, a compass sensor, a compass, a speaker, a microphone, a windshield wiper automatic control, a digital signal processor, an automatic defogger control, a collision avoidance control, a lane departure warning module, an electro-optic mirror element control module, a supplemental illuminator module, a photo sensor and a processor.

3. An apparatus as in claim 1 configured as a rearview mirror assembly comprising, said rearview mirror assembly comprising at least one device selected from the group comprising: an imager, an automatic exterior light control module, a moisture sensor module, a compass sensor, a compass, a speaker, a microphone, a windshield wiper automatic control, a digital signal processor, an automatic defogger control, a collision avoidance control, a lane departure warning module, an electro-optic mirror element control module, a supplemental illuminator module, a photo sensor and a processor.

4. An apparatus as in claim 1 configured to function as at least one of the group selected from: an automatic exterior light control system, a moisture sensing system, a windshield wiper control, a defroster control, a defogger control, a lane keeping system, a lane departure warning system, a security system, a vision system, an adaptive cruise control system, a parking aid system, a blind spot warning system, a sun load sensing system, a blue sky detection system, a tunnel detection system, a day time running lights control system, a security system, an air bag activation system, a rear vision system, an occupancy detection system, a monitoring system, a collision avoidance system, an accident recreation system and an image acquisition system.

5. An apparatus comprising:

at least one image sensor; and

at least one processor configured to receive at least a portion of at least one image from said at least one image sensor, wherein a dynamic aim of said at least one image sensor is a function of said at least one image, such that said processor modifies pixel data of said received at least a portion of at least one image, takes a first derivative of said modified pixel data, thresholds said modified pixel data, and takes a second derivative of said threshold modified pixel data.

6. An apparatus as in claim 5 configured as a rearview mirror assembly comprising a stationary housing, said stationary housing comprising at least one device selected from the group comprising: an imager, an automatic exterior light control module, a moisture sensor module, a compass sensor, a compass, a speaker, a microphone, a windshield wiper automatic control, a digital signal processor, an automatic defogger control, a collision avoidance control, a lane departure warning module, an electro-optic mirror element control module, a supplemental illuminator module, a photo sensor, and a processor.

7. An apparatus as in claim 5 configured as a rearview mirror assembly comprising, said rearview mirror assembly comprising at least one device selected from the group comprising: an imager, an automatic exterior light control module, a moisture sensor module, a compass sensor, a compass, a speaker, a microphone, a windshield wiper automatic control, a digital signal processor, an automatic defogger control, a collision avoidance control, a lane departure warning module, an electro-optic mirror element control module, a supplemental illuminator module, a photo sensor, and a processor.

8. An apparatus as in claim 5 configured to function as at least one of the group selected from: an automatic exterior light control system, a moisture sensing system, a windshield wiper control, a defroster control, a defogger control, a lane keeping system, a lane departure warning system, a security system, a vision system, an adaptive cruise control system, a parking aid system, a blind spot warning system, a sun load sensing system, a blue sky detection system, a tunnel detection system, a day time running lights control system, a security system, an air bag activation system, a rear vision system, an occupancy detection system, a monitoring system, a collision avoidance system, an accident recreation system, and an image acquisition system.
