Patent ID: 7443590

Claim:
A single-focus imaging apparatus including an array of imaging devices, the apparatus comprising: an optical system including a first imaging system that produces a focused image; a first imaging plane on which an image produced through the first imaging system is formed; and a second imaging system group including an array of second imaging systems, each second imaging system including a second imaging device and a corresponding lens through which at least part of the image formed on the first imaging plane is formed on a second imaging plane on the second imaging device, the second imaging devices being distinct from each other and the corresponding lenses being distinct from each other, wherein at least the position of the respective corresponding lenses, the distance between the corresponding lens and the second imaging device, and the angle of view are determined as parameters of each second imaging system in accordance with the position of the second imaging plane that changes depending on the distance between the imaging apparatus and an object and the second imaging system group includes a first subgroup including an array of second imaging systems each having first type parameters determined in accordance with the position of the second imaging plane located when the distance between the imaging apparatus and the object is a first length; and a second subgroup including an array of second imaging systems each having second type parameters determined in accordance with the position of the second imaging plane located when the distance between the imaging apparatus and the object is a second length shorter than the first length.
