Abstract: An information processing apparatus includes a processor and a memory connected to or incorporated in the processor. The processor acquires reference imaging device information corresponding to a position, an imaging direction, and an angle of view of a reference imaging device, and generates the virtual viewpoint image by using the reference imaging device information as a reference, on a condition that an instruction to start generating a virtual viewpoint image based on a plurality of images obtained by imaging an imaging region with a plurality of imaging devices is given.

Abstract: An information processing apparatus includes an acquisition unit that acquires a free viewpoint video based on at least one image among a plurality of images obtained by imaging an imaging region by a plurality of imaging apparatuses, and a reference video, the free viewpoint video indicating the imaging region in a case in which the imaging region is observed from a specific viewpoint position and a specific visual line direction, and an execution unit that executes a specific process in a case in which a difference degree between the free viewpoint video acquired by the acquisition unit and the reference video acquired by the acquisition unit is equal to or more than a first threshold value.

Abstract: An information processing apparatus includes a detection unit that detects a three-dimensional position and a posture of an object in an instruction three-dimensional region having an enlarged or reduced relationship with an observation three-dimensional region in which a virtual viewpoint and a virtual visual line are defined, a derivation unit that derives the viewpoint and the visual line corresponding to detection results of the detection unit depending on positional relationship information indicating a relative positional relationship between the observation three-dimensional region and the instruction three-dimensional region, and an acquisition unit that acquires a virtual viewpoint image showing a subject in a case in which the subject is observed with the viewpoint and the visual line derived by the derivation unit, the virtual viewpoint image being based on a plurality of images obtained by imaging an imaging region included in the observation three-dimensional region by a plurality of imaging apparatuses.

Abstract: An illumination control unit selectively turns on strobe devices and a strobe light emitting unit. An image acquisition unit captures an image of an object through an imaging element and acquires individual illumination images. An individual irradiation area detection unit detects individual irradiation areas which are areas irradiated with each illumination light component in the imaging range of the imaging element on the basis of the individual illumination images. An irradiation area image generation unit generates an irradiation area image obtained by inserting division marks indicating each individual irradiation area into the image of the object. An irradiation area image output unit displays the irradiation area image on a rear display unit. The user observes the irradiation area image and can simply recognize each individual irradiation area.

Abstract: In a variable magnification viewfinder device, information displayed on a liquid crystal panel and a viewfinder image are combined with each other through a prism. When a variable power lens is inserted in a viewfinder optical path, viewfinder magnification is changed. Based on the change in the viewfinder magnification, brightness of a backlight unit is changed and luminance of the information displayed on the liquid crystal panel is changed. In a viewfinder field of view, the information and the viewfinder image are displayed at substantially the same brightness.
