Provided is an observation apparatus capable of adjusting visibility of an image and of an optical image of a subject in consideration of an intensity of ambient light in a case where the image is displayed by being superimposed on the optical image. The observation apparatus (30) includes an optical system (32), a display mechanism (34) that displays an image based on a signal generated by an imaging element (20), and a light shielding mechanism (36) of which a light shielding rate is variable, and the optical image has a first optical region (OP1) and a second optical region (OP2). The display mechanism (34) superimposes the image on the first optical region (OP1) to display both the image and the optical image in an observable manner by a user. The light shielding mechanism (36) is disposed in an optical path between the subject and the display mechanism (34) and has a first light shielding region (36a) to be superimposed on the first optical region (OP1) and a second light shielding region (36b) to be superimposed on the second optical region (OP2). Control processing of controlling light shielding rates of the first light shielding region (36a) and of the second light shielding region (36b) based on the intensity of the ambient light is executed by the control unit (40) with respect to the light shielding mechanism (36).

A signal processing device performs a displaying process in a display unit on the basis of a parameter being predetermined in an image capture device provided with an anamorphic lens.

The present technology relates to a control apparatus, a control method, and a program for giving a sense of imaging to a user. There are provided a processing unit that processes data based on pixel signals output from a plurality of pixels, and a display control unit that causes a display unit to display an image based on the data processed by the processing unit as a through image. The display unit displays a mark indicating a recording process in response to an instruction of recording the data together with the through image displayed on the display unit. The mark is displayed at each of four corners of the display unit. Alternatively, the mark is displayed near a frame of autofocus. The present technology is applicable to an imaging device.

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.

A device mount mounts a display with an aspect ratio greater than or less than 1:1. A camera is integrated into the device mount at a position above a top edge of the display. A hinge of the device mount rotates the mounted display. A mounting plate of the hinge couples the hinge to the device mount, and a shuttle of the hinge couples the display to the hinge to rotate the display between a landscape mode and a portrait mode. The hinge is configured such that rotation of the display from landscape mode into portrait mode translates a center of the display away from the camera on a vertical axis and rotation of the display back to landscape mode translates the center of the display towards the camera on the vertical axis.

A digital camera is provided with a vertically long camera body having an approximately rectangular solid shape. An LCD panel provided in a rear surface of the camera body is arranged such that longitudinal directions of the display screen and the camera body correspond to each other. The digital camera is operated through a touch panel provided in a lower portion of the display screen. In a taking mode, an image is displayed in a small size on an upper portion of the display screen. In reproducing, the camera body is rotated sideways by 90 degree. In a reproducing mode, display posture of the image is also rotated by 90 degree, and the image is displayed in a large size on the entire display screen.
