Original Abstract Submitted
techniques are described that utilize continuous flash lighting, e.g., with automatic activation/deactivation and brightness control of a flash lighting element in an electronic image capturing device. depth sensing, in combination with front and/or rear lux sensing, is performed at the device and used to evaluate the lighting on the object of interest being captured and/or the overall scene light levels. a lighting element (e.g., a single- or multi-channel flash element) may be controlled automatically based on the depth, front and rear lux sensing, or a combination thereof. the lighting element's intensity may be automatically adjusted in a smooth and gradual manner, e.g., utilizing ranges of acceptable lux values and/or non-linear lighting element activation functions.
