Patent Images
1. An image processing system for a front-view image sensor, comprising:
- an image sensor so configured and arranged on an own vehicle as to pick up a front-view image in front of the own vehicle;
a region setting block so constructed and arranged as to set image processing regions to cover on the front-view image various portions one after another, wherein the portions have different positions in a direction remote from the own vehicle;
a feature extracting block so constructed and arranged as to extract a feature out of image processing of the portions of the front-view image covered by the image processing regions set by the region setting block; and
a presence judging block so constructed and arranged as to judge the presence of an obstacle based on the feature extracted by the feature extracting block.

Abstract
An image processing system includes an image sensor that picks up a front-view image in front of an own vehicle. Image processing regions are set to cover on the front-view image, picked up by the image sensor, various portions one after another, which narrow, in area, with different positions in a direction remote from the own vehicle. A feature is extracted out of image processing a portion of the front-view image covered by the image processing regions. The extracted feature is used for vehicle detection.

16. An image processing method for a front-view image sensor, comprising:
-
obtaining a front-view image in front of an own vehicle;
setting image processing regions to cover on the front-view image, at one after another various portions, which narrow in area, at different positions in a direction remote from the own vehicle;
extracting a feature out of the image by image processing a portion of the front-view image covered by a set image processing region; and
judging a presence of an obstacle based on the feature extracted by the feature extracting step.
