An image pickup apparatus includes a multifocal optical system in which first and second focal lengths on short and long focal length sides is optically selected; an image pickup device for converting an optical image into an image signal; an image processor which processes the image signal to form an original image; a trimming device for trimming the original image formed by the image processor; a drive controller for switching the optical focal length when the set angle-of-view of the trimming device changes between the second angle-of-view and a third angle-of-view which is smaller than the second angle-of-view; and a memory for storing an original image formed by the image processor at a focal length before the optical focal length is switched by the drive controller. The trimming device forms trimmed images of set angle-of-views while the optical focal length is switched.
