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： A zoom optical system includes at least two optical-element groups and a variable optical-property optical element. The two optical-element groups are movable in a magnification change and have a magnification varying function or a compensating function for compensating for a shift of an image surface caused by the magnification change. The optical element has a focusing function and is disposed on the image side of the optical-element groups. According to this configuration of the zoom optical system, it is possible to attain a zoom optical system and an imaging apparatus using the zoom optical system that have as small a number of movable lenses as possible, are very small in size, and work with an extremely low power consumption and low operation noise.

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
