1. An image processing apparatus comprising:
a sub-image generation unit configured to generate sub-images by dividing a first image in a lateral direction, the first image being one of a left image and a right image, the left image and the right image being captured by a stereo camera through a windshield provided with an electric heating wire;
a luminance ratio map generation unit configured to sequentially select one of the sub-images and generate map data based on the selected sub-image and a second image, the map data indicating a ratio between luminance values, the second image being another of the left image and the right image; and
an electric heating wire pattern estimation unit configured to perform an estimation of a wiring pattern of the electric heating wire based on the map data regarding each of the sub-images.
