PROBLEM TO BE SOLVED: To provide an in-vehicle image processing device capable of recognizing a road surface sign line such as a parking frame line with high accuracy from an image taken by an in-vehicle camera.SOLUTION: The in-vehicle image processing device carries out a tracking process of tracking a road surface sign line La1 that moves in an image processing area 32 with the movement of an own vehicle 10, and an interpolation process of computing a position of the road surface sign line La1 that has moved from inside the image processing area 32 to the outside, based on a behavior of the own vehicle 10 and storing the computation results as an interpolation line La1'. If the sine line La2 in the image processing area 32 is arranged on an extended line of the interpolation line La1', the in-vehicle image processing device carries out a sign line determining process of determining that the road surface sign line La2 as cooperating with the interpolation line La1', constitutes a part of the same road surface sign line La. |
