<P>PROBLEM TO BE SOLVED: To provide an image processor for a vehicle, the vehicle and an image processing program for the vehicle, allowing detection of a lane mark on a road on which the vehicle travels from an image with high accuracy by processing the image obtained by imaging the circumference of the vehicle so as to reduce influences of variation of local luminance and color on a road surface. Ž<P>SOLUTION: This image processor 10 for the vehicle has: a kernel setting means 12 for setting size of kernels which is within a prescribed range wherein a width in a prescribed direction is larger than a width in the prescribed direction of an image portion of the lane mark to the obtained image; a smoothing means 13 for smoothing the obtained image by filtering using the kernels for the smoothing having the set size; a variation degree calculation means 14 for calculating a variation degree of a pixel value of each pixel of the obtained image to the image after the smoothing; and a pixel value replacement means 15 for replacing a pixel value of a pixel which is of the obtained image and has the variation degree not larger than a prescribed value with a pixel value of a pixel corresponding to the pixel of the image after the smoothing.
