Vehicle-mounted surrounding object recognizing apparatus and drive support apparatus using the same
First Claim
1. A vehicle-mounted surrounding object recognizing apparatus, comprising:
- a camera that captures an environment surrounding an own vehicle; and
an image processing device;
whereinthe image processing device is configured to process an image captured by the camera to calculate, using the single image at every processing cycle, an index value of a color component with respect to an image portion having a luminance value greater than a predetermined value, and determine whether the image portion is related to a light from a surrounding vehicle based on a relationship between the calculated index value of a color component and a predetermined threshold, andthe predetermined threshold is changed according to a lighting status of a forward lighting device of the own vehicle.

6. A vehicle-mounted surrounding object recognizing apparatus, comprising:
-
a camera that captures an environment surrounding an own vehicle; and an image processing device;
whereinthe image processing device is configured to process an image captured by the camera to calculate an index value of a color component with respect to an image portion having a luminance value greater than a predetermined value, and determine whether the image portion is related to a light from a surrounding vehicle based on a relationship between the calculated index value of a color component and a predetermined threshold, and the predetermined threshold is changed according to a lighting status of a forward lighting device of the own vehicle, wherein the predetermined threshold is changed according to whether the image portion having a luminance value greater than the predetermined value is located in a region where low beam light is projected but near infrared light is not projected, a region where low beam light and near infrared light are projected, or a region where low beam light is not projected but near infrared light is projected.
