To provide a technique which can appropriately recognize a parking frame drawn on a road surface.SOLUTION: An image processing device includes: a search part which searches for a division line dividing parking possible regions where parking is allowed based on a photographic image obtained by a camera photographing the periphery of a vehicle; and a recognition part which recognizes a parking frame constituted by the parking possible regions and a pair of parking impossible regions sandwiching the parking possible region based on the research result of the search part, in which the recognition part detects a range where the parking impossible region, the parking possible region and the parking impossible region are continuously aligned in this order and recognizes the parking frame.SELECTED DRAWING: Figure 2 【課題】路面上に描かれる駐車枠を適切に認識することができる技術を提供する。【解決手段】画像処理装置は、車両の周辺を撮影するカメラで得られた撮影画像に基づき、駐車が認められる駐車可領域を区画する区画線を探索する探索部と、前記探索部の探索結果に基づき、前記駐車可領域と当該駐車可領域を挟む一対の駐車不可領域とで構成される駐車枠を認識する認識部と、を備え、前記認識部は、前記駐車不可領域、前記駐車可領域、前記駐車不可領域の順に領域が連続して並ぶ範囲を検出して前記駐車枠を認識する。【選択図】図２
