There is provided an image processing device capable of easily reducing a burden related to image recognition and obtaining stable recognition performance even when a posture of a vehicle changes from moment to moment. An image processing deviceincludes a storage unitand an image processing unit. The storage unitstores a pickup image acquired by an image pickup unitmounted on the vehicle and an inclination angle transmitted from an inclination angle sensorthat detects the inclination angle of the vehicle. The image processing unitperforms image processing on the pickup image. The image processing unitassociates the pickup image in an inclined state with the inclination angle based on a time difference Δt between a time from when the pickup image in the inclined state is acquired by the image pickup unituntil the acquired pickup image is stored in the storage unit, and a time from when the inclination angle is detected by the inclination angle sensoruntil the detected inclination angle is stored in the storage unit. The image processing unitgenerates a recognition image in a non-inclined state, which is used for image recognition of the pickup image, from the pickup image in the inclined state based on the inclination angle associated with the pickup image.
