IMAGE PROCESSING SYSTEM AND CAMERA SYSTEM

Provided are an image processing system and a camera system capable of appropriately detecting an object in a background difference type even when an exposure condition of a camera changes. The camera system includes an image processing system 100. The image processing system 100 includes an original image acquisition unit 101 that acquires a first original image and a second original image, a luminance correction unit 104 that acquires a luminance-corrected image by correcting a luminance value of the second original image such that a difference from a luminance value of the first original image decreases in accordance with an exposure condition related to each of the original images, and a background difference type object detection unit 105 that detects an object by acquiring a background difference based on the luminance-corrected image.
