Abstract: The imaging lens includes, successively in order from a position closest to an object side: a first lens group that remains stationary with respect to an image plane during focusing; and a focus lens group that moves along an optical axis during focusing. Assuming that a maximum image height is Ymax, and a focal length of the imaging lens is f, and a sum of a back focal length in terms of an air-equivalent distance and a distance on the optical axis from a lens surface closest to the object side to a lens surface closest to the image side is TL, the imaging lens satisfies Conditional Expressions (1) and (2).

Abstract: 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).

Abstract: An electronic apparatus using a liquid crystal display device, a display control method used in the liquid crystal display device, and a non-transitory recording medium for storing a display control program, sets a region having a larger area of an information display region and a background region as a transmission region and a region having a smaller area as a shielding region in an illumination mode. A tint change of the shielding region caused by a TN type liquid crystal and a light source for backlight is reduced, and thus, it is possible to make the tint change depending on the viewing direction unremarkable.

Abstract: A camera shake detection unit detects a camera shake value. A shutter button that is a shutter operating unit is operated in imaging. A prediction range calculation unit calculates a prediction range of a camera shake value that occurs in a case where the shutter button is operated, on the basis of a history of the camera shake value after a previous operation of the shutter button. A camera shake display controller displays a locus of camera shake on an EVFLCD on the basis of the camera shake value detected by the camera shake detection unit before the operation of the shutter button, and displays the prediction range on the EVFLCD using a leading end of the locus as a starting point.

Abstract: An imaging unit generates image data of a video as a plurality of frame data that are continuous in a temporal order. An imaging control unit generates metadata indicating an imaging condition of the imaging unit in association with the frame data in a case in which the imaging condition is changed. An output control unit and an external output I/F add the metadata to the frame data and output the frame data to which the metadata is added as video data before demosaicing. In addition, in a case in which a data amount of the metadata associated with the frame data exceeds an addable data amount, the output control unit and the external output I/F add metadata selected based on a priority from among the metadata associated with the frame data to the frame data.
