发明名称 Imaging apparatus and exposure control method used for the same
摘要 An imaging apparatus includes a shutter drive section, an aperture blade drive section, an ND filter drive section, a light intensity detection section, a memory, and a control section. The shutter drive section opens and closes a shutter for a light receiving surface of a solid state image sensor. The aperture blade drive section drives an aperture blade forming an aperture. The ND filter drive section adjusts the position of an ND filter against the aperture. The control section calculates the exposure control voltage representing an exposure amount from the light intensity signal output from the light intensity detection section, and reads out the F value and the shutter speed corresponding to the exposure control voltage from the exposure control table stored in the memory so as to avoid a partial application state of the ND filter, for controlling respective drive sections.
