Abstract: An image sensing device and a control device of an illumination device thereof are provided. The control device includes a control circuit, an operation circuit, and multiple driving signal generators. The control circuit generates multiple control signals. The operation circuit performs a logical operation on the control signals and an image capturing signal to generate multiple operation results. The driving signal generator respectively provides multiple driving signals to the illumination device according to the operation results, and the driving signals respectively have multiple different output powers.

Abstract: A driving event recording method and system for non-image-based car accident cause determination are disclosed. The system includes an external-event determination unit, an internal-driving-behavior-event determination unit, and a processor electrically connected to both determination units. The method is carried out as follows. The external-event determination unit generates information about an external event, and at the same time the internal-driving-behavior-event determination unit generates information about an internal driving behavior event. The processor receives the external-event information and the internal-driving-behavior-event information and uploads both pieces of information to a cloud storage space in a text or program code format for storage in a blockchain.
