Embodiment Construction
[0030] figure 1 is a block diagram of a system for compensating for the offset of a solid-state imaging device. This system is applied in a camera device 100 and includes a sensor 102 , an arithmetic circuit 104 , a delay circuit 106 , an automatic control device 108 , a motor drive device 110 and a magnetic energy component 112 . The sensor 102 is coupled to the solid-state imaging device 114 of the imaging device 100, and continuously detects the change data of the movement of the solid-state imaging device 114 during the action to generate a corresponding sensing signal, wherein the sensor 102 can be an inclination signal sensor or an acceleration sensor, The solid-state imaging device may be a Charge Coupled Device (CCD). The operation circuit 104 is used to receive the sensing signal output by the sensor 102, and output the corresponding operation signal after processing it, wherein the operation circuit 104 can be an integrator, a differentiator or a multiplier. The de...

The invention relates to a method for compensating deviation of a solid-state imaging device, including: obtaining a first sensing signal and a second sensing signal; comparing the two signals to obtain error amount representing deviation of the solid-state imaging device; outputting variable voltage according to the error amount to drive a magnetic energy assembly; moving the solid-state imagingdevice by using the magnetic energy assembly to compensate deviation of the solid-state imaging device. The method for compensating deviation of a solid-state imaging device of the invention has advantages that structure is simple, optical picture stabilization effect can be achieved just by combination of a signal processing circuit, a sensor and a magnetic energy assembly, which reduces image smearing caused by shake when photographing, compared to the prior art, design of the invention is simpler, and manufacture cost is reduced.
Description
technical field [0001] The invention relates to an imaging device and its signal processing technology, in particular to a system and method for compensating the offset of a solid-state imaging device in an imaging device. Background technique [0002] Generally, there is a problem of unclear imaging caused by hand vibration in camera devices, especially for thin and light digital cameras, because the stability of the digital camera held by the user is not enough, often at the moment of pressing the shutter, because the use of The shake of the hand or the force of pressing the shutter with the finger causes the camera to vibrate, resulting in a blurred image. [0003] The existing solution is to install an angular velocity sensor and a position sensor in the camera device, so as to respectively detect the angle change information and the position change information of the camera device during its movement, and generate corresponding sensing signals. Angular velocity sensors...
