Abstract
Optical systems for use in digital cameras are provided. The systems can be switched between three optical paths ( ): a first path ( ) for through-the-lens (TTL) viewing; a second path ( ) for recalling previously taken pictures from a microdisplay ( ); and a third path ( ) in which pictures are taken using an electronic sensor ( ), e.g., a CMOS sensor. The optical systems employ a zoom objective lens unit ( ), e.g., a 3:1 zoom, an erector lens unit ( ), and an eye lens unit ( ). They can also employ an image size adjusting lens unit ( ) for equalizing the TTL and recalled images presented to the user. To facilitate integration with the electronic components of a digital camera and to provide a “book” format for the camera, the first and second optical paths ( ) lie in a single plane and each includes two folding mirrors ( for the first path; for the second path) and the third optical path ( ) has a single folding mirror ( ) so that a portion of that path is in the single plane and a portion is orthogonal to that plane.
