Finder system of a camera

摘要

A finder system of a camera has an eye direction detecting device for detecting a direction in which a photographer's eye is looking and a display for displaying information related to operating parameters of the camera in a view field of the finder system. The finder system further includes a display prism for transmitting light from a projector of the display to the view field, and a detecting prism for transmitting light reflected from the eye that is projected by a light emitting element of the eye direction detecting device to a light detecting element of the eye direction detecting device. The display prism and the detecting prism are formed as a single block prism.
