Claim One:
1. An image processing device, comprising: an image synthesis processing unit that sequentially receives continuous-photographed images photographed under different exposure conditions as an input image, performs a synthesis process of the input image and an intermediate synthetic image serving as a previously processed image, and generates an output image, wherein the image synthesis processing unit includes a region determining unit that classifies configuration pixels of the input image and the intermediate synthetic image into a noise pixel, an effective pixel, or a saturation pixel according to a threshold value, an update method deciding unit that decides a synthesis processing method of a pixel unit according to a combination of pixel classification results of the corresponding pixels of the input image and the intermediate synthetic image, and an image update processing unit that performs a synthesis process of the input image and the intermediate synthetic image according to an update method decided by the update method deciding unit, and generates the output image.
