摘要： 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.

摘要： A method, system, and computer program product controlling flash behavior of a camera during capture of image data. The method includes identifying a target object from among a plurality of objects in a current scene. The method further includes determining whether a distance to the target object is within an effective flash range associated with at least one flash module of an image capturing device. The method further includes measuring, via at least one camera, an ambient light level within the current scene and comparing the measured ambient light level to a predetermined flash light threshold. The method further includes, in response to determining the target object is within the effective flash range and the measured ambient level is less than the predetermined flash light threshold, triggering at least one flash module of the image capturing device to illuminate the current scene during capture of image data by the at least one camera.

摘要： The present disclosure relates to a method and a device for correcting a color temperature of a flash lamp in the field of the computer technology. The method includes: obtaining a first color temperature value of a gray point region in a first image, in which the first image is obtained by capturing a scene when the flash lamp is closed; searching for an image region corresponding to the gray point region in a second image, in which the second image is obtained by capturing the scene when the flash lamp is open; and correcting the color temperature for the light compensation of the flash lamp according to a difference obtained by subtracting the first color temperature value from the second color temperature value.

摘要： An imaging system includes a digital camera and illuminating devices. The digital camera includes an imaging optical system, a shutter, a shutter driving mechanism, an imaging element, an illumination control unit, and a wireless I/F. The shutter is a focal-plane shutter. In a case in which a main imaging operation is performed in a plural illumination control mode, the shutter driving mechanism drives the shutter to generate a transition period for which a partial exposure region is transferred to the lower side of an imaging area of the imaging element over time. The illumination control unit controls the emission times of the illuminating devices to be different times within the transition period.

摘要： An electronic device with a camera and a display that can output light to achieve a desired appearance of skin tone is provided. The display outputs light having a color temperature for lighting during picture taking. The electronic device analyzes a color temperature value of a capturing environment and compares that value with a preset value, calculates a difference value according to the comparing, and controls the display to adjust the color temperature of the light accordingly. A color temperature adjusting method of the electronic device is also provided.

摘要： 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.

摘要： An apparatus for photographing by using an electronic flash has a photography controller that carries out a pre-flash photography by emitting strobe light in a pre-flash exposure period and subsequently carries out a main flash photography by emitting strobe light; and an exposure adjuster that sets at least one exposure value associated with the pre-flash photography and/or the main flash photography. The exposure adjuster sets an aperture value of a diaphragm that suppresses an occurrence of saturation in image-pixel signals that are generated in an image sensor in the pre-flash exposure period. The photography controller drives the diaphragm in accordance to the set aperture value for the pre-flash photography.

摘要： A lens-fitted photo film unit provides a daylight photography mode to select no flash emission and the small stop, a daylight synchro photography mode to select normal flash emission and the small stop, and a night view synchro photography mode to select reduced flash emission and the large stop. The small stop is composed of the small stop aperture of f/16 and an ND filter of transmittance of 25% to be attached to cover the small stop aperture. The shutter speed is set at 1/64 sec. in any modes. The photo film preloaded in the lens-fitted photo film unit has ISO sensitivity 3200. The stable photographing is achieved under the wide range of brightness by the changeover of the stop, without the change of the shutter speed. In brightness of EV 9 to 11, the exposure amount becomes proper either in the daylight photography mode and in the night view synchro photography mode.
