Abstract To provide an image processing system that can accurately estimate TTC between a target object and a vehicle.SOLUTION: A system comprises an object detection part 241 that detects an object from an image, an area separation part 242 that separates the image area where the object is detected into multiple subareas, an area selection part 243 that selects a subarea for calculating a magnification rate from the multiple subareas, and a TTC calculation part 244 that calculates the collision prediction time (TTC) until the object collides with the target object based on the magnification rate calculated using the selected partial areas.SELECTED DRAWING: Figure 2 【課題】対象物体と車両間のＴＴＣを高精度に推定することのできる画像処理装置を提供する。【解決手段】画像から物体を検知する物体検知部２４１と、前記物体を検知した画像領域を複数の部分領域に分離する領域分離部２４２と、前記分離した複数の部分領域から拡大率算出に用いる部分領域を選択する領域選択部２４３と、前記選択された部分領域を用いて算出した拡大率から、対象となる前記物体と衝突するまでの衝突予測時間（ＴＴＣ）を算出するＴＴＣ算出部２４４と、を備える。【選択図】図２
