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.

1. Field of the Invention
The invention relates to image pickup systems, and in particular to an image pickup system which integrates a data sensed by an angular velocity signal to compensate vibration.
2. Description of the Related Art
The invention can be more fully understood by reading the subsequent detailed description and examples with references made to the accompanying drawings, wherein:
FIG. 1 shows an embodiment of an image pickup system;
FIG. 2 shows a flowchart of the image pickup method in the embodiment;
The following description is of the best-contemplated mode of carrying out the invention. This description is made for the purpose of illustrating the general principles of the invention and should not be taken in a limiting sense. The scope of the invention is best determined by reference to the appended claims.
FIG. 1 shows an embodiment of an image pickup system. The image pickup system 100 can be implemented as an image pickup device with vibration compensation. An example using an image pickup system includes a digital camera but is not limited thereto. As shown, the image pickup system 100 comprises a gyro sensor 10, a Hall effect sensor 20, a processing module 30, a driving unit 40, an image sensor 50, a high pass filter 60 and amplifiers 70A and 70B.
The gyro sensor 10 can be disposed in the image pick device to detect variations in inclination and generate corresponding sensing data. For example, the gyro sensor 10 generates an angular velocity signal of the image pickup device, the angular velocity signal can be variations in an angular velocity ({right arrow over (ω)}) under different times as shown in FIG. 3B, or can be variations in an angular acceleration ({right arrow over (a)}) under different times as shown in FIG. 3C.
