In-vehicle image correcting device and night driving view field supporting device
First Claim
1. An in-vehicle image correcting device for correcting an image picked up by a near-infrared camera ahead of one'"'"'s own vehicle in which an obstacle is difficult for a driver to visually recognize, comprising:
- image capturing means for capturing the image picked up by said near-infrared camera; and
correcting means for correcting the image captured by said image capturing means so that a density of a pixel having a higher density than an obstacle density representative of the density of a pixel corresponding to said obstacle becomes lower than the obstacle density.

Abstract
An in-vehicle image correcting device for correcting an image picked up by a near-infrared camera ahead of one'"'"'s own vehicle in which an obstacle is difficult for a driver to visually recognize captures the image picked up by the near-infrared camera; and corrects the image captured by the image capturing means so that a density of a pixel having a higher density than an obstacle density representative of the density of a pixel corresponding to the obstacle becomes lower than the obstacle density. In this configuration, the image picked up by the, near-infrared camera is corrected so that the obstacle can be easily recognized.

5. An in-vehicle image correcting device for correcting an image picked up by a near-infrared camera ahead of one'"'"'s own vehicle in which an obstacle is difficult for a driver to visually recognize, comprising:
-
image capturing means for capturing the image picked up by said near-infrared camera;
road area detecting means for detecting a road area representative of a road on the image captured by said image capturing means;
unnecessary area specifying means-an unnecessary area specifying means for specifying an unnecessary area of the image which may not be visually recognized by the driver on the basis of the road area detected by said road area detecting means; and
correcting means for correcting the image captured by the image capturing means so that the pixel corresponding to the unnecessary area specified by said unnecessary area specifying means has a density lower than an obstacle density representative of a density of the pixel corresponding to said obstacle. - View Dependent Claims (6)

7. An in-vehicle image correcting device for correcting an image picked up by a near-infrared camera ahead of one'"'"'s own vehicle in which an obstacle is difficult for a driver to visually recognize, comprising:
-
image capturing means for capturing the image picked up by said near-infrared camera;
irradiated area information storing means for storing irradiated area information representative of an irradiated area irradiated with a headlight of one'"'"'s own vehicle on the image captured by said image capturing means;
correcting means for correcting the image captured by said image capturing means so that the pixel corresponding to said irradiated area has a lower density than an obstacle density representative of the density of a pixel corresponding to an obstacle.
