ABSTRACT:
An image observing apparatus capable of reducing reflections caused by incoming light. The apparatus includes an image display such as a liquid crystal cell with at least one optical system disposed between the image display and the observer's eye. A polarizing element is disposed between the optical system and the observer's eye. The apparatus is suited for use with electronic view finders, such as those used with video cameras. Because of the location of the polarizing element, incoming light and incoming light reflected from optical surfaces in the apparatus are decreased in intensity without any attenuation of the light forming the image. Thus, the visibility of the image is improved.
