A display device is provided with an input unit for inputting a detection signal from a detection unit capable of detecting the brightness of ambient light around a dimming member. The display device is also provided with a control unit which, on the basis of the detection signal input by the input unit, controls at least one of the optical transmittance of the dimming member and the operation of a projector to adjust an image projected onto the dimming member to a display state corresponding to the brightness of the ambient light.

An electronic device includes a communication unit that communicates with a battery, a storage unit that stores a first identification information of the battery, and a determination unit that determines whether the communication unit is capable of performing a predetermined communication with the battery, in a case where a second identification information of the battery received from the battery is matched with the first identification information stored in the storage unit.

Webcam systems and mount assemblies are disclosed that can dispose a camera at or near a middle of computer monitor whereby a user is viewed by the camera from a face-front position, and wherein the position of the camera is vertically and laterally manually adjustable (without tools) to facilitate a variety of positions according to need or desire. The webcam systems and mount assemblies further may be used with any of a tablet computing device, a laptop computer, a free-standing computer monitor, etc., and may be mounted to any edge or an adjacent structure while permitting disposing the camera at or near a center of the monitor.

An image capturing apparatus on which an accessory including a first mount is mountable includes a second mount. The second mount is configured to allow bayonet coupling to the first mount of the accessory. The second mount includes a plurality of terminals disposed in a circumferential direction, and a terminal holder configured to hold the plurality of terminals. Each of the plurality of terminals is electrically connectable to a terminal of the accessory. The terminal holder has a height level difference in a center-axis direction of the second mount. The plurality of terminals include a first terminal configured to be used to detect mounting of the accessory on the image capturing apparatus. The first terminal is disposed further in a mount direction of the accessory than the other terminals among the plurality of terminals on a first stage of the terminal holder.

An unobtrusive augmented reality (AR) system can be used to assist the wearer in every day interactions by projecting information from the contact lens display onto the retina of the wearer's eye. The unobtrusive augmented reality system includes a necklace and a contact lens display that are unobtrusive to the wearer and the wearer's surrounding environment. The necklace of the unobtrusive augmented reality system generates power and data for the contact lens displays. The necklace and contact lens display include conductive coils inductively coupled by a magnetic field. The inductive coupling allows data and power generated by the necklace to be transferred to the contact lens display. A projector in the contact lens display projects images generated from the data onto the retina of the wearers eye.

A control device controls an image capturing device installed in a wearable device. A display device is capable of communicating with the control device. The control device is configured to: cause the display device to display a plurality of candidate images corresponding to images of a subject captured with different exposure conditions; detect a selection of one of the candidate images; and cause the image capturing device to capture an image of the subject with an exposure condition corresponding to the one of the candidate images as selected.

A tamperproof video camera includes a video lens, an antenna; a wireless, transceiver, a processor, a battery compartment comprising a door, and an electronic lock. The processor receives signals through the wireless transceiver to lock or unlock the battery compartment's door. In response, the processor sends signals to the electronic lock to lock or unlock the battery compartment's door. The electronic lock is configured to lock or unlock the battery compartment's door in response to receiving the signals from the processor.

A control method applied to a photographing apparatus that includes a lens, an external device, and a body communicatively connected to the lens and the external device. The control method includes the body sending a shutter opening command to the lens; the lens sending a trigger signal to the body according to the shutter opening command, the trigger signal including a first pulse and a second pulse; and the body receiving the trigger signal sent from the lens, triggering a resetting operation of an image sensor inside the body according to the first pulse and triggering activation of the external device according to the second pulse.

A digital camera with a printer is a digital camera with a printer and includes a communication unit that communicates with a digital camera with a printer that is another apparatus, and an image composition unit that generates a composite image in which a first image captured by the digital camera with a printer that is an owned apparatus and a second image captured by the other apparatus are composited, in which the communication unit transmits the composite image to the other apparatus. A user of the other apparatus can also obtain the composite image. Accordingly, the composite image can be enjoyed by capturing images using a plurality of cameras.

An image sensor includes an imaging device, an optical system including a liquid lens to form an image of a subject on an imaging surface of the imaging device, and a controller that performs a refractive power control process of adjusting an application voltage applicable to the liquid lens to control a refractive power of the liquid lens, and a recognition process of analyzing image data from the imaging device to recognize predetermined information about the subject. The controller is operable in a plurality of operation modes each with a different wait period from a change in the application voltage to the liquid lens in response to the refractive power control process to a start of the recognition process.
