发明名称 Camera with viewing point measuring arrangement - has control unit automatically setting focus to field of view of photographer by means of viewing axis measuring assembly in automatic mode but blocks measuring function of latter in manual mode
摘要 Information is derived from an ocular (1), a dichroitic mirror (a), a light pick-up lens (4), an i.r. LED (5c), an image sensor (6) and a computing processor (9) to produce registration data as regards the point of view of the photographer. A focus setting measuring assembly (108) registers the focus state of the taking lens (101) with reference to the field of view according to the derived information. A focus setter (110) adjusts the taking lens according to the focus setting state. A control unit (109) stops information being generated w.r.t. the view point of the photographer when a manual setting is selected for focussing. A motor drive can be assigned to the lens. ADVANTAGE - Easier handling of camera when changing mode.
