An accessory includes a plurality of communication contacts that includes a first contact, and a control unit that notifies an electronic apparatus of a communication request by changing a signal level of the first contact from a first signal level to a second signal level different from the first signal level, and transmits information indicating a communication factor in response to a reception of a request for the information indicating the communication factor in response to a notification of the communication request. In a case where the control unit notifies the electronic apparatus of the communication request via the first contact in response to a start of a power supply, the control unit performs predetermined communication without receiving the request for the information indicating the communication factor or transmitting the information indicating the communication factor.

An accessory strobe device for a mobile device may operate to provide illumination at the same time as an internal built-in strobe (flash) of the mobile device. The accessory strobe device may receive a single, unidirectional signal from the mobile device that provides signals related to the timing of the internal strobe. The accessory strobe device may process the received signal to control its illumination using the timing and relative intensity levels of the internal strobe during metering and main (normal) flash operations associated with a camera on the mobile device. With the accessory strobe device operating using timing and relative intensity levels in a predetermined relationship with the timing and relative intensity levels of the internal strobe, the accessory strobe device may be used to complement the internal strobe during the metering and main (normal) flash operations for the camera.

An illumination device capable of appropriately suppressing a temperature rise of a light emitting part, wherein the illumination device comprises a light emitting part configured to emit light for illumination, a cooling part configured to cool the light emitting part. The illumination device acquires a temperature at a first position, acquires a temperature at a second position that is less susceptible to a temperature change of the light emitting part than the first position, determines presence or absence of light emission of the light emitting part, and controls driving of the cooling part based on the acquired temperature at the first position, the acquired temperature at the second position and a determination result of the presence or absence of light emission.

A videotelephony lighting system and a method of using the same is provided. The videotelephony lighting system includes one or more light bars that can prop themselves up or be supported by a stand so as to be positioned in different configurations to light a user's face while they are on a video call. The videotelephony lighting system embodies a simple approach wherein each lightbar provides only one linear high-CRI LED light source having a 2700-3000 K CCR.

A tissue imaging system comprising a computing device, tissue visualization application, image capturing unit, and an illumination unit, is configured to capture measurement data. The visualization application extracts visualizations of tissue health indicators from the measurement data. The application generates an interface with one or more interface elements corresponding to the visualization of tissue health indicators.
