In this case, F-numbers in two directions perpendicular to each other on a plane perpendicular to the optical axis are different. Decentration takes place in one of the two directions and the F-number in a direction perpendicular to a decentering direction is smaller than that in the decentering direction. When the F-number in the decentering direction is represented by FNY and the F-number in the direction perpendicular to the decentering direction is represented by FNX, the optical system satisfies the following condition: 1.1

摘要： The present invention relates to an image display apparatus, e.g. a head-mounted image display apparatus, in which an image from a single image display device is led to two eyes without using a half-mirror, thereby allowing observation of a bright image. The image display apparatus has an optical path distributing mirror 1 for distributing the image of a single display device 10 to an optical path for a right eye and an optical path for a left eye, and an ocular prism 2R for the right eye and an ocular prism 2L for the left eye, which are placed on the right- and left-hand sides, respectively, of the optical path distributing mirror 1. In the optical path for the right eye, display light from the display device 3 is reflected by a reflecting surface 1R of the optical path distributing mirror 1 and passes through a first surface 21R of the decentered prism member 2R to enter the prism, in which the light is totally reflected by a second surface 22R, which serves also as a fourth surface 24R, and back-reflected by a third surface 23R to exit from the prism through the fourth surface 24R. The light is led to an exit pupil 4R for the right eye to project an enlarged image of the display device 3 into the right eye. The same is true in the optical path for the left eye.

摘要： An optical element assembly includes a first optical element, a second optical element, and a positioning holder member. The first optical element has engageably shaped portions in a peripheral portion of an effective area on a first injection surface through which the effective luminous flux passes. These engageably shaped portions respectively correspond to one engageably shaped portions formed on one opponent surface of the positioning holder member that opposes the first injection surface. The second optical element has engageably shaped portions in a peripheral portion of an effective area on a second incident surface through which the effective luminous flux passes. These engageably shaped portions respectively correspond to the other engageably shaped portions formed on the other opponent surface of the positioning holder member that opposes the second incident surface. The positioning holder member has in a predetermined portion, an optical diaphragm aperture that permits transmission of light between the one opponent surface and the other opponent surface. An image pickup apparatus includes the optical element assembly, an image pickup device, and an image data producing portion.
