FLASH GENERATOR FOR A FLASH TUBE
The present disclosure relates to a flash generator for providing power supply to a flash tube so that the flash tube rapidly provides a light output adapted to FP-sync, Flat Peak. The flash generator comprises a capacitor bank, an output and a switch configured to switch a current flow from the capacitor bank via the output to provide a variable power via the output. The flash generator further comprises a controller for controlling the switch, whereby by controlling the on time of the switch, the generator is operative to provide, during a time period of 100 to 2000 μs during a peak time period within the time period, an average power at least 4 times higher than the average power provided during the other time period within the time period, whereby the flash tube during the peak time period becomes fully ignited.

Infrared-assisted pre-flash
Methods, systems, and devices for operating a camera-enabled device are described. The camera-enabled device may emit, via a first light emitting source, an infrared light in a physical environment and determine time-of-flight information associated with a target object in the physical environment based on the emitted infrared light. The camera-enabled device may estimate one or more exposure settings based on the time-of-flight information, and emit, via a second light emitting source, a visible light in the physical environment based on the estimated one or more exposure settings. As a result, the camera-enabled device may capture an image of the physical environment based on the emitted visible light and the estimated one or more exposure settings.

Electronic device and control method therefor
An electronic device according to various embodiments comprises a camera module, a communication module, and a processor electrically connected to the camera module and the communication module, wherein the processor acquires an exposure value for an image inputted using the camera module, acquires lighting control-related information from at least one lighting device on the basis of a network connected using the communication module, and can generate a signal for adjusting at least one piece of the lighting control-related information of the at least one lighting device on the basis of the exposure value and a preset lighting control-related information set value. In addition, other embodiments are possible.
FLASH METERING FOR DUAL CAMERA DEVICES
Methods, systems, and devices for image processing are described. Devices with one or more sensors (e.g., devices with multiple cameras, such as a dual camera device) may perform flash metering techniques, using an auxiliary camera, during a flash duration used for main camera image capture. For example, a dual camera device may control camera flash parameters (e.g., flash duration, flash power), via auxiliary camera flash metering, during main camera image capture (e.g., during main camera exposure for image capture operations). A main camera may begin exposure and a flash may be initiated. During the flash, an auxiliary camera may be configured to perform flash metering operations (e.g., via images captured by the auxiliary camera). Based on flash metering information from the auxiliary camera, the dual camera device may configure or adjust camera settings (e.g., exposure settings, flash duration, flash end time, flash power) during main camera exposure and image capture.

Control apparatus, accessory, imaging apparatus, and imaging system capable of switching light emission modes for imaging
A control apparatus includes a controller configured to switch a simultaneous light emission mode that causes all of the at least three light source units to emit lights and a sequential light emission mode that causes the at least three light source units to sequentially emit the lights in association with imaging. The controller causes the at least three light source units to sequentially emit the lights in synchronization with each of at least three imaging signals transmitted from the imaging apparatus in the sequential light emission mode. The controller is configured to switch between the simultaneous light emission mode and the sequential light emission mode based on information from a selector provided in at least one of the imaging apparatus and the accessory and configured to select the simultaneous light emission mode and the sequential light emission mode.
