Location-dependent dictionaries for pedestrian detection in a vehicle-mounted camera system
View Patent ↗A camera module includes a camera imaging a region outside a rear end portion of a vehicle and a storage storing first and second dictionary information corresponding to a first area and a second area. When the camera take an image of a pedestrian and a detected latitude and longitude correspond to the first area, the camera module recognizes the image of the pedestrian based on the first dictionary information, outputs a first vehicle control signal based on a recognition result, and outputs a status the first dictionary information is used. When the camera takes an image of a pedestrian and a detected latitude and longitude correspond to the second area, the camera module recognizes the image of the pedestrian based on the second dictionary information, outputs a second vehicle control signal based on a recognition result, and outputs a status that the second dictionary information is used.

the camera module has a second mode not outputting the first status that the first dictionary information is used and the second status that the second dictionary information is used.
7. The vehicle according to claim 5 , wherein
the display circuit has a first mode outputting the first status that the first dictionary information is used and/or the second status that the second dictionary information is used, and
the display circuit has a second mode not outputting the first status that the first dictionary information is used and the second status that the second dictionary information is used.
8. The vehicle according to claim 1 , wherein
a second mode of the display circuit is switched to a first mode of the display circuit when the camera has taken an image in the second mode.
9. The vehicle according to claim 8 , wherein
the image is a third image; and
the first mode is switched to the second mode when the camera has taken a fourth image in the first mode.
10. The vehicle according to claim 6 , further comprising:
a manipulation circuit,
wherein the second mode is switched to the first mode when the manipulation circuit receives a manipulation in the second mode.
11. The vehicle according to claim 10 , wherein
the manipulation is a first manipulation; and
the first mode is switched to the second mode when the manipulation circuit receives a second manipulation in the first mode.
12. The vehicle according to claim 10 , wherein
the manipulation circuit is a touch panel disposed so as to overlap on the display circuit.
13. The vehicle according to claim 10 , wherein
the manipulation circuit is a mechanical switch disposed in a peripheral portion of the display circuit.
14. The vehicle according to claim 1 , wherein
the direction includes a forward direction that the vehicle is moving forward and a rearward direction that the vehicle is moving rearward; and
the one end portion of the vehicle is an end portion of the vehicle located in the rearward direction.
15. The vehicle according to claim 14 , wherein
the display circuit displays the image, which is taken by the camera, while the vehicle is moving in the rearward direction.
16. The vehicle according to claim 5 , wherein
the position information detection circuit is disposed inside the body of the camera module.
17. A camera module configured to be installed in a vehicle, the vehicle having a vehicle body, at least one wheel which is attached to the vehicle body and moves in a direction by rotating, a signal cable, and a display circuit configured to output an image on the basis of a signal transmitted by the signal cable, the camera module configured to be arranged at one end portion of the vehicle body, the camera module comprising:
a body;
a camera which is disposed inside the body and images a region outside the one end portion of the vehicle body; and
a memory which is disposed inside the body and stores first dictionary information corresponding to a first area and second dictionary information corresponding to a second area,
wherein the camera module outputs an image taken by the camera to the signal cable,
