An imaging apparatus includes: a first display; a second display; a speaker configured to output a sound effect in response to a predetermined operation; and a controller configured to control an output of the sound effect from the speaker. The controller is operable to: in a case of the first display set as operable, cause the speaker to output a sound effect having a first frequency characteristic in response to the predetermined operation; and in a case of the second display set as operable, cause the speaker to output a sound effect having a second frequency characteristic in response to the predetermined operation, the second frequency characteristic being different from the first frequency characteristic.

A digital camera has a finder device that enables an optical image which is observable from an observation position and a display image (imaging range frame) of an OLED display to be simultaneously visible by superimposing the display image on the optical image, the digital camera including a system control unit that performs a control of sequentially changing a display position of the display image in the OLED display in a first range, in which a maximum width of the first range is 6 arc-minutes or more and 18 arc-minutes or less in terms of an observation angle (visual angle) in a case where the first range is observed from the observation position.

An image capturing device includes a movable mirror including a half mirror and circuitry to set a superimpose display mode that superimposes and displays an optical image of a finder optical system and an electronic image captured by an image sensor, and a consecutive photographing mode, control the movable mirror to rotate between a mirror-down position, in which the mirror is inserted in a photographing optical path, reflects light to a finder optical system, and transmits the light to an image sensor, and a mirror-up position in which the mirror is retracted from the photographing optical path and the light passes through to the image sensor, and prohibit the movable mirror from rotating to the mirror-up position and maintain the mirror-down position, when the superimpose display mode and the consecutive photographing mode are both set.

Provided are an imaging apparatus capable of ensuring favorable visibility of display in a finder from when power is applied, a finder display control method of the imaging apparatus, and a finder display control program of the imaging apparatus. A viewfinder (30), which superimposes a display of a finder LCD (36) on an optical image of a subject observed through an observation optical system (32), includes a variable ND filter (40) that adjusts the light amount of the optical image of the subject. While power of the digital camera is turned off, information about the time is acquired, and the target transmittance of the variable ND filter (40) is updated on the basis of the information about the transmittance determined for each time zone. In a case where the target transmittance is updated, the variable ND filter (40) is driven to change the transmittance of the variable ND filter (40) to the target transmittance.

A finder optical system includes a display element and a diffractive optical element that is disposed on an eye point side of the display element so as to continue from the display element. The diffractive optical element includes a first base, a first layer that is laminated on the first base and includes a first diffractive optical surface on a surface thereof opposite to the first base, a second base, and a second layer that is laminated on the second base and includes a second diffractive optical surface on a surface thereof opposite to the second base. The first diffractive optical surface and the second diffractive optical surface are in close contact with each other.

An observation optical system is configured to observe an image displayed on an image display plane and includes a negative lens and a positive lens. At least one of the negative lens and the positive lens has a lens surface having a Fresnel shape. A predetermined condition is satisfied.

An electronic device is configured to obtain an eye image in which an eye that looks at a display is captured. The electronic device includes at least one memory storing instructions; and at least one processor which executes the stored instructions causing the at least one processor to: perform line-of-sight detection, based on the obtained eye image; and provide, based on at least one of a position of a pupil image in the eye image and a number of corneal reflection images in the eye image, a predetermined notification regarding a method of adjusting a viewing state in which the display is visually perceived.
