Document Type and Number:
Japanese Patent JP6867505
Kind Code:
B2
Abstract:
Provided are an imaging apparatus capable of maintaining favorable visibility of display in a finder, a finder display control method of the imaging apparatus, a finder display control program of the imaging apparatus, and a viewfinder. The viewfinder (30) includes an observation optical system (32), a finder LCD (36), a beam splitter (34) that superimposes display of the finder LCD (36) on an optical image of a subject observed through the observation optical system (32), an electronic variable ND filter (40) that adjusts a light amount of the optical image of the subject incident into the beam splitter (34), a transmittance measurement unit (90) that measures the transmittance of the electronic variable ND filter (40) changing over time in a case where the transmittance of the electronic variable ND filter (40) is switched, and a finder LCD display control unit (110b) that controls the light amount of the display device in real time on the basis of the result of measurement of the transmittance measurement unit (90). The finder LCD display control unit (110b) controls the light amount of the finder LCD (36) so as to keep constant a light amount ratio of the optical image of the subject observed through the observation optical system (32) and the display of the finder LCD (36) superimposed on the optical image.
