A camera viewfinder comprises an electronic display apparatus that is configured for the display of images that are recorded by an image sensor of an electronic camera. The camera viewfinder further comprises two mirrors for reflecting the images displayed by the display apparatus, of which at least one mirror is a free-form surface mirror whose reflective surface is formed as a free-form surface that does not have any continuous translation symmetry or rotational symmetry. At least one of the free-form surface mirrors is adjustable to at least partially compensate a vision defect of a user.

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.

Provided are an imaging device, a finder device, a method of controlling an imaging device, a method of controlling a finder device, a control program for an imaging device, and a control program for a finder device capable of preventing burn-in of a display device that displays display information on an optical image of a subject observed through an optical finder in a superimposed manner, and preventing a relative positional relationship between a position of the display information displayed on the display device and a range, in which imaging is actually performed, from being changed.

Display information, such as a visual-field frame, displayed at a prescribed position of an OLED display (218) is moved on the OLED display (218), and burn-in of the OLED display (218) is prevented. An imaging range of an image sensor (201) is moved corresponding to movement of the display information, and a relative positional relationship between a position of the display information displayed on the optical image of the subject observed through the optical finder in a superimposed manner and a range to be actually imaged is prevented from being changed.

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.

An image pickup apparatus includes a touch detecting unit configured to be capable of detecting a touch operation performed on a touch panel; a viewfinder display unit configured to display a display indicating a set value of an item inside a viewfinder; and a control unit configured to execute control such that, in a case where a subject image is visible through the viewfinder, a set value of a first item is changed in response to a touch operation performed on the touch panel when a predetermined operation relating to image pickup is not being performed, and a set value of a second item that is different from the first item is changed in response to a touch operation performed on the touch panel when the predetermined operation is being performed.
