Abstract: A light source apparatus and a driving apparatus thereof are provided. The driving apparatus includes a first node, a second node, a clock synchronization unit, a control unit, a switch unit, and a feedback unit. The driving apparatus receives an AC voltage through the first and the second nodes. The clock synchronization unit converts the AC voltage into a clock synchronization signal. The control unit converts a preset brightness value into a driving current, outputs an adjusting signal according to a timing of the clock synchronization signal, and modulates a pulse width of the adjusting signal according a feedback signal. The switch unit determines whether or not the AC voltage is provided to the light source module according to a control of the adjusting signal. The feedback unit detects a load state of the light source module, and outputs the feedback signal to the control unit according a detection result.

Abstract: Method and device for light signal reception. This device can selectively execute a comparison mode or a gain mode. In the device, a transmitter transmits a light beam to a target. A receiver receives the light beam reflected from the target and outputs a corresponding received signal. In the comparison mode, it is determined whether a pulse in the received signal is higher than a reference voltage level. When the pulse is higher the reference voltage level, the pulse is outputted. The gain mode is executed and the received signal is amplified and output when no pulse is higher than the reference voltage level in the received signal. The method and device of the present invention can be applied to range finders, the comparison mode is executed during short-distance measurement and the gain mode is executed during long-distance measurement thereby measuring the target distance from several meters to a thousand meters.

Abstract: Camera systems and methods with vibration compensation. The system comprises a first sensor, a second sensor, and a processing module. The first sensor detects an angle variation of a movement of a camera device to generate first sensed data. The second sensor detects a position movement of an image sensor of the camera device to generate second sensed data. The processing module takes the first derivative of the second sensed data, and calculates control information according to the first sensed data and the differential of the second sensed data. The processing module enables a drive device to adjust the position of the image sensor based on the control information.
