  • Patent number: 7679646
    Abstract: 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.

  • Patent number: 7633526
    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.

  • Publication number: 20080259171
    Abstract: A method for compensating an offset of a solid-state imaging device includes obtaining a detection signal representing the offset of the solid-state imaging device disposed on a stage, generating a corresponding control voltage and control signal according to the detection signal; generating a corresponding regulation voltage according to the control voltage, generating a corresponding driving voltage according to the regulation voltage, outputting a driving signal according to the driving voltage and the control signal, and generating a magnetic force according to the driving signal to move the stage.
