Real-time light-measuring system for single-lens reflex cameras |
摘要 |
A light-measuring system for single-lens reflex cameras wherein the light coming from an object to be photographed as reflected at the image-pickup surface is reflected once again by a partially reflecting means disposed in the photographing light path, so that this latter reflection light is measured on its own optical axis, to enable to perform the real-time measurement of light with a high precision.
