Abstract
A display member 31 is placed in a position which, as seen from an eyepiece optical system 25, is optically equivalent to the focal plane of an objective optical system 21 and a reflector mirror 33 capable of movement between an electronic image observing position B where the rays of image-bearing light from the display member 31 are reflected toward the eyepiece optical system 25 and an optical picture observing position A where the reflector mirror 33 gets clear of the optical path between the focal plane of the objective optical system 21 and the eyepiece optical system 25 is placed between the focal plane of the objective optical system 21 and the eyepiece optical system 25.
Claims8
In a digital camera having viewfinder optics displaced from imaging optics and a display member for providing an illuminated display of an electronic image taken with an imaging device located in the focal plane of said imaging optics, said viewfinder optics comprising an objective optical system, an erecting optical system for inverting and reversing right and left an object image formed with the objective optical system, and an eyepiece optical system for observing the image reverted and inverted with the erecting optical system, the improvement wherein said display member is placed in a position which, as seen from said eyepiece optical system, is optically equivalent to the focal plane of said objective optical system, and a reflector mirror capable of movement between an electronic image observing position where the rays of image-bearing light from said display member are reflected toward the eyepiece optical system and an optical picture observing position where said reflector mirror gets clear of the optical path between the focal plane of said objective optical system and the eyepiece optical system is placed between the focal plane of said objective optical system and said eyepiece optical system.
A digital camera having a CCD imaging system, the digital camera comprising:
- a camera body;
- a viewfinder system which obtains an image of an object separately from the CCD imaging system to guide the image to an eyepiece lens provided to the camera body;
- a display located within the camera body and connected to the CCD imaging system to display an image of the object obtained by the CCD imaging system;
- and
- a movable mirror which selectively guides one of the image of the object obtained by the viewfinder system and the image of the object displayed on the display to the eyepiece lens.
