Abstract:
1. An image processing device for processing an image captured by an image pickup device for capturing an image of a target area, the image processing device comprising: a background object reference image estimation unit configured to estimate a reference image of a background object with no motion based on input images inputted sequentially from the image pickup device; a background object optical flow calculation unit configured to calculate an optical flow of the background object by calculating local fluctuations of the input images based on the input images and the reference image of the background object; a moving object reference image estimation block configured to estimate a reference image of a moving object with motion based on input images inputted sequentially from the image pickup device; a moving object heat haze fluctuation calculation block configured to calculate a fluctuation due to heat haze on the moving object in the input images based on the input images and the reference image of the moving object; and a motion correction unit configured to correct the input images by using the optical flow calculated by the background object optical flow calculation unit and the fluctuation due to heat haze on the moving object calculated by the moving object heat haze fluctuation calculation unit to remove the local fluctuations in the input images.
