An image processing device is enabled to appropriately restore a contrast of a camera image. An in-vehicle camera has an image capture unit that captures images of surroundings of a vehicle through a windshield of the vehicle. A hood is disposed below the image capture unit and is present within an angle of view of the image capture unit. The control unit includes a luminance acquirer that acquires a luminance parameter indicating a degree of luminance of the hood appearing in a camera image, a whitish blur degree calculator that calculates a degree of whitish blur of the camera image caused by a reflection of natural light by the hood and the windshield in accordance with the luminance parameter, and a contrast corrector that corrects a contrast of the camera image in accordance with the whitish blur degree.
