IMAGING DEVICE, IMAGING METHOD, AND IMAGING DEVICE DESIGN METHOD

摘要

The present invention relates to an image pickup apparatus, a method for capturing an image, and a method for designing the image pickup apparatus capable of realizing a fixed focal length image pickup apparatus of high resolution and fine resolution at a low cost by disposing a plurality of image pickup elements therein. An image pickup device 31 is of a focal coincidence type having a plurality of image pickup elements, such as CCD sensors 62-1 to 62-3, arranged in an array. That is, the image pickup device 31 has an optical system including a first image formation system 41 for forming an image of focal coincidence, a field lens 43 disposed in an image formation plane or in the vicinity of the image formation plane of the first image formation system, and a second image formation system group formed by a plurality of second image formation systems arranged in an array and including an image pickup element CCD sensor 62-K (K is a value between 1 and 3 in this example) for capturing the image formed on itself and a zoom lens 61-K for reforming a predetermined part of the image formed on the image formation plane on the CCD sensor 62-K. The present invention is applicable to a digital still camera and a digital video camera including a plurality of image pickup elements.
