Abstract

PURPOSE: To eliminate parallax and to detect the blur of a subject by sending light from the subject to an area sensor as a blur detection sensor by using a pericle.
CONSTITUTION: Part of luminous flux transmitted through a pericle mirror 34 is guided to a phase difference AF detection module 36 by an AF detection mirror 7 and luminous flux reflected by the pericle mirror 34, on the other hand, is entered into a pentagonal prism 38 through a condenser lens 37. One surface 38a of the pentagonal prism 38 is a half-mirror and guides part of the incident luminous flux out the pentagonal prism 38 and this luminous flux is passed through a blur detection optical system 40 and reflected by a reflecting mirror 43 to reach the blur detection sensor 44. Thus, the light from the subject is sent to the area sensor 44 as the blur detection sensor by using the pericle mirror 34 to enable a TTL type camera to perform blur detection by an image detection system.
