Image pickup systems capable of preventing blurred images are provided, in which a first sensor detects a variation in inclination of an image pickup device to generate a first sensing data, a second sensor detects a position movement from an image sensor in the image pickup device to generate a second sensing data and a driving unit is coupled to the image sensor. A processing module receives the first and second sensing data, integrates the first sensing data, calculates the integrated first sensing data and the second sensing data to obtain control information, and enables the driving unit to adjust the position of the image sensor according to the control information.

Image pickup systems

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.

Camera systems with vibration compensation and methods thereof

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.

Method and device for light signal reception

A Rangefinder capable of long and short distance measurement in company with compass measurement. The rangefinder includes distance measurement unit, a compass sensing unit and a processor. The rangefinder can selectively execute a comparison mode or a gain mode. The comparison mode is executed during short-distance measurement and the gain mode is executed during long-distance measurement. The compass measurement unit senses a terrestrial magnetism to obtain first and second magnetic sensing signals. The processor estimates a distance between the target and the rangefinder according to the measurement signal from the distance measurement unit and determines a compass orientation of the target according to the first and second magnetic sensing signals.
