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.
