An on-vehicle image processing apparatus, comprising: a photographing device (1a, 1b, 1c, 1d) configured to photograph a road surface around a vehicle so as to obtain a photographed image; an image creation section configured to create an overhead view image showing a situation where a circumference of the vehicle is looked down from above the vehicle, based on the photographed image obtained by the photographing device (1a, 1b, 1c, 1d); an extraction section configured to extract a road surface sign including a parking frame around the vehicle by using the overhead view image created by the image creation section; a detection section configured to detect a road surface noise, an obstruction noise, and an attached substance noise that are to be observed when the extraction section extracts the road surface sign; characterized by a selection section configured to select a selected image region from among a plurality of partial photographing regions in the photographed image and a plurality of partial overhead view regions in the overhead view image, depending on a predetermined relationship between regions, which includes the plurality of partial photographing regions and the plurality of partial overhead view regions, and three types of noises, including a road surface noise, an obstruction noise, and an attached substance noise; and a parking frame recognition section configured to recognize a parking frame in the selected image region; wherein: the road surface noise is not a component of an extraction object but exists near the road surface sign or the parking frame that is the extraction object, and the road surface noise includes a parking frame noise or a white line noise that adversely affects extraction of the extraction object; the obstruction noise includes a solid object noise that adversely affects extraction of an extraction object due to reflection of an object existing in space other than a substantially flat surface on which the road surface sign or the parking frame that is the extraction object is drawn; and the attached substance noise includes a water droplet noise or a dirt noise due to an attached substance to the photographing device (1a, 1b, 1c, 1d). a photographing device (1a, 1b, 1c, 1d) configured to photograph a road surface around a vehicle so as to obtain a photographed image;
