An imaging device and its image processing method for creating an image with less blur from a small number of images under different exposure conditions in a shortened processing time. The imaging device (10) captures an image by means of an optical system (11) and an imaging element (12) in a short exposure time with a high resolution and much noise and images in a long exposure time with low resolution and less noise. After signal processing by signal processing section (13), a CPU (14) detects the position variation between captured images and blurs, separates the edge blur and the noise by using the threshold from the two difference images, combines the two images at a varied combination ratio, and thereby creates an image with no blur and reduced noise.
