1. An image capture device, comprising: a first image capture element and a second image capture element; an optical system which is capable of forming a first image which is in focus on an image capture plane of the first image capture element and forming a second image which is out of focus on an image capture plane of the second image capture element; and an image processing section for processing a first signal obtained from the first image capture element and a second signal obtained from the second image capture element, wherein the image processing section is configured to add the first signal and the second signal to generate a signal of a degraded image, and is configured to produce a restored image from the signal of the degraded image, the restored image having reduced camera shake blur and reduced out-of-focus blur.
