Image observing apparatus and imaging apparatus utilizing the image observing apparatus
First Claim
1. An image observing apparatus comprising:
- an optical element including a first face inclined relative to an observer, a second face comprised of a reflective concave side, and a third face which light from an image enters so as to have overall a positive refractive power;
line-of-sight detecting means for detecting a line of sight of the observer including a light source provided on an observing side of said optical element to illuminate a fore eye portion of the observer and a light receiving means for receiving an image of the fore eye portion; and
light reflecting means, provided in an observing side of the first face, between the first face and the light source, for reflecting the light emanating from the light source,wherein the light from the image entering the third face is reflected by the first face, is convergently-reflected to a first face side by the second face, and emerges from the first face, andwherein the light, from the light source, reflected at the fore eye portion of the observer is reflected by said light reflecting means and enters said light receiving means.

Abstract
An image observing apparatus according to the present invention includes: an optical element including a first face inclined relative to an observer, a second face composed of a reflective concave side, and a third face which the light from the image enters so as to have overall a positive refractive power; a line-of-sight detecting device for detecting a line of sight of the observer including a light source to illuminate a fore eye portion of the observer and a light receiving device for receiving an image of the fore eye portion; and a light reflecting device, provided in an observing side of the first face, for reflecting the light emanating from the light source. In this image observing apparatus, the light from the image entering the third face is reflected by the first face, is condenser-reflected at a first face side by the second face, and is irradiated from the first face. Moreover, the light, from the light source, reflected at the fore eye portion of the observer is reflected by the light reflecting device and enters the light receiving device.

12. An imaging apparatus comprising:
-
an imaging means for taking an image; a recording means for recording the image taken by said imaging means; and observing means including; an optical element including a first face inclined relative to an observer, a second face comprised of a reflective concave side, and a third face which light from one of the taken image and the recorded image enters so as to have overall a positive refractive power; line-of-sight detecting means for detecting a line of sight of the observer including a light source provided on an observing side of said optical element to illuminate a fore eye portion of the observer and a light receiving means for receiving an image of the fore eye portion; and light reflecting means, provided in an observing side of said first face, for reflecting the light emanating from said light source, wherein the light, from the image entering said third face is reflected by said first face, is convergently-reflected to a first face side by said second face, and emerges from said first face, and wherein the light from said light source, reflected at the fore eye portion of the observer is reflected by said light reflecting means and enters said light receiving means. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
