Title:
A photographing instrument, a main part of a photographing instrument, and a control method of a photographing instrument
Document Type and Number:
Japanese Patent JP6244062
Kind Code:
B2
Abstract:
A subject information acquisition section acquires a subject distance difference, which is distance difference between a main subject and a subject farthest from the main subject, on the basis of an imaging signal sent from an imaging element. A program diagram storage section stores a first program diagram where an aperture value is fixed at an open aperture value at a first amount of exposure EV1 or less, and stores a second program diagram where an aperture value is fixed at an open aperture value at a second amount of exposure EV2, which is greater than the first amount of exposure EV1, or less. An imaging exposure determination section selects the second program diagram in a case where an APD filter is disposed on the optical path and a case where the subject distance difference is equal to or greater than a threshold value and there is an imaged scene in which a blurred image tends to occur, and selects the first program diagram in a case where the subject distance difference is less than the threshold value and there is an imaged scene in which a blurred image is hard to occur.
