<p>PROBLEM TO BE SOLVED: To move and display an index excellent in visibility at an optional position in a finder image with inexpensive and simple constitution by controlling light projecting timing based on plural pieces of excitation information and moving and displaying the index in the finder image in two different directions. SOLUTION: The direction of light projected by a light projection means constituted of the light source 41 and a mask 42 is guided in a two-dimensional direction in the finder image by utilizing the excitation of a pitch shake detection sensor 43 and a yaw shake detection sensor 44. By controlling the light projecting timing of the light source 41 and the mask 42 based on the excitation information from the sensors 43 and 44 which are excited at different frequency, the index is displayed within the finder image. Therefore, the index excellent in the visibility is moved and displayed at the optional position in the finder image plane by the inexpensive and simple constitution.</p> |
