Patent ID: 8059162

Claim:
A single-focus imaging apparatus including an array of imaging devices, the apparatus comprising: an optical system including a first imaging system configured to produce a focused image; at least one imaging plane on which an image produced through the first imaging system is formed; and a second imaging system group including a first subgroup having a first array of second imaging systems and a second subgroup having a second array of second imaging systems, each second imaging system including an imaging device and a lens through which at least part of the image formed on the at least one imaging plane is formed on the imaging device; and a processor, wherein at least a position of the lens, a distance between the lens and the imaging device, and an angle of view are determined as parameters of each second imaging system of the first and second subgroup, and are independently adjusted for each subgroup based on a position of the imaging plane, the position of the imaging plane changing based on a distance between the imaging apparatus and an object, the processor is configured to join images output by second imaging systems having shared parameters, and the imaging devices of the first subgroup are spatially offset from the imaging devices of the second subgroup in a direction of the optical axis.
