IMAGE PROCESSING DEVICE, IMAGE GENERATING SYSTEM, METHOD, AND PROGRAM

摘要

An image generation device includes an image acquisition section for acquiring the first and second moving images having different resolutions and different frame rates or different exposure times from each other; a light amount determination section for determining, based on a pixel value of each of pixels in each of frame images of the first and second moving images, whether or not each pixel is saturated or blocked-up-shadowed; and an image processing section for generating, from the first and second moving images, a new moving image having a frame rate which is equal to or higher than the frame rate of the first and second moving images and having a resolution of each frame image which is equal to or higher than the resolution of the first and second moving images. For a pixel not determined as being saturated or being blocked-up-shadowed, the image processing section generates a new moving image fulfilling a first condition which indicates that an error between a pixel value of each of the acquired first moving image and second moving image and a sum of pixel values of frame images of the new moving image corresponding to the pixel value temporally and spatially is smaller than a prescribed value; and for a pixel determined as being saturated or being blocked-up-shadowed, the image processing section generates a new moving image which does not fulfill the first condition.
