Abstract
A photographic apparatus includes an image sensor, a processing unit, a light emitting unit, and a control unit. The image sensor is configured to capture a continuous image, and generate an exposure signal according to an exposure sequence corresponding to the continuous image. The processing unit is electrically connected to the image sensor and is configured to calculate an exposure value according to the continuous image. The control unit is electrically connected to the image sensor, the processing unit, and the light emitting unit. According to the exposure value, the control unit may select a continuous mode to drive the light emitting unit to emit light continuously, or a pulse mode to cooperate with the exposure signal to drive the light emitting unit to pulse light, in order to fill light while capturing the continuous image.
