Patent attributes
An image pickup apparatus includes a multifocal optical system having at least two different focal lengths; an image pickup device for converting an optical image formed by the multifocal optical system into an image signal; a first image processor for forming an original image defined by an object image at each focal length of the multifocal optical system with the image signal received from the image pickup device; and a second image processor for trimming the original image formed by the first image processor. An object image of an angle-of-view corresponding to an intermediate focal length between the two focal lengths of the multifocal optical system is complemented by a trimmed image formed by the second image processor.
