The image display apparatus includes an image capturing optical system, an image sensor, a display element, and an ocular optical system. An optical axis of the image capturing optical system and an optical axis of the ocular optical system are located on a same straight line. An image capturing view angle of the image capturing optical system is larger than a display view angle of the ocular optical system. The display element is configured to display, of an image generated by using a signal from the image sensor, an area corresponding to the display view angle. When d represents a distance between a position of an entrance pupil of the image capturing optical system and a position of the exit pupil of the ocular optical system, the condition of 20 mm≤d≤60 mm is satisfied.

Image display apparatus

A synchronization control apparatus includes a control unit configured to control a plurality of imaging devices that capture an image, and a determination unit configured to determine a target region from which an image is acquired from each of the plurality of imaging devices, and to determine a synchronization signal corresponding to the target region in each of the plurality of imaging devices, wherein the determination unit determines the synchronization signal and the target region in each of the plurality of imaging devices so as to temporally synchronize images acquired from the plurality of imaging devices.

Apparatus, apparatus control method, and recording medium, for synchronizing a plurality of imaging devices

An electronic apparatus comprises a detection unit configured to detect electrical characteristics of main power, via a composite cable, changed in accordance with subsidiary power supplied through the composite cable configured to perform power supply and bi-directional signal transmission; and a control unit configured to control the main power supplied through the composite cable in accordance with a result of detection by the detection unit.

Electronic apparatus and control method for electronic apparatus

A display apparatus including a left portion corresponding to a left eye of a user and a right portion corresponding to a right eye of the user, each portion includes at least one image capturing unit configured to capture an image of a physical space, and a display unit configured to display a video image based on a captured image obtained by the image capturing unit. The image capturing unit is arranged on an inside of an angle formed by lines extending from the pupil of the corresponding eye to each side of the display unit.

Display apparatus

A configuration reduces a total data amount required for processing or transmitting image data by splitting an image captured by an image capturing unit into a first image for calculating a position and an orientation of the image capturing unit and a second image serving as a background for generating a virtual image.

Information processing device, image display device, image display system, and information processing method

A first image and a second image with resolutions different from each other are generated from an image captured by an imaging unit, and the first image and the second image are subject to different types of image processing. A virtual image is generated by calculating a position and an orientation of the imaging unit based on the processed first image. A composite image is generated by combining the generated virtual image with the second image subjected to the image processing, and the generated composite image is used as a display image.
