1. A digital camera system comprising: an image capturing apparatus for capturing an image; and an image processing apparatus for performing an imaging process on an image captured by the image capturing apparatus, wherein said image capturing apparatus has an optical system including a lens and an image sensor for converting subject light incident via said optical system into an electric signal, said image capturing apparatus captures a blurred image in which a blurring is generally caused intentionally by changing a relative positional relation between said lens and said image sensor and also captures a normal image in which a blurring is not caused intentionally, and said image processing apparatus combines said normal image and said blurred image, thereby generating a composite image having a no-blurring area in which a blurring is not intentionally caused and a blurred area in which a blurring is intentionally caused.
