Embodiment Construction

[0058] figure 1 Shown is a block schematic diagram of a system for compensating the offset of a solid-state imaging device according to an embodiment of the present invention. This system is located in the imaging device 100, and achieves the effect of compensating the offset variation of the solid-state imaging device 120 arranged on the mobile platform 110 by adjusting the mobile platform 110, wherein the solid-state imaging device 120 can be a charge coupled device (Charge Coupled Device) Device, CCD).

[0059]The system includes a vibration sensing device 130 , an amplifier 135 , a micro control device 140 , a voltage regulation circuit 150 , a voltage regulation device 160 , a motor drive device 170 , a magnetic energy device 180 and a position sensing device 190 . The vibration sensing device 130 is used to detect the deviation change caused by the vibration of the camera device 100 during the operation period, and then generate a corresponding sensing signal. Wherein...

Abstract

The invention relates to a method for compensating the offset of a solid-state imaging device, including that a sense signal is acquired; wherein, the sense signal is the offset information of the solid-state imaging device arranged on a mobile platform; the control voltage and the control signal are correspondingly generated according to the sense signal; the regulation voltage is generated correspondingly according to the control voltage; the drive voltage is generated correspondingly according to the regulation voltage; the drive signal is outputted according to the drive voltage and the control signal; the magnetic force is generated to regulate the mobile platform according to the drive signal. The system and the method for compensating the offset of the solid-state imaging device can be adopted to reduce the image streaking caused by the vibration during the photographing process; meanwhile, different drive voltages can be generated correspondingly according to the detected sense signals; thereby, the power consumption used for compensating the offset is saved and the compensation is processed effectively.

Description

technical field [0001] The invention relates to a compensation system and method in an imaging device, in particular to a system and a method for compensating the offset of a solid-state imaging device in the imaging device. Background technique [0002] Generally, there is a problem of hand vibration in the camera device, especially for the light and thin digital camera, because the stability of the digital camera held by the user is not enough, therefore, often at the moment of pressing the shutter, because the user holds the digital camera Long-term shaking or the force of the finger pressing the shutter causes the camera to vibrate, thus blurring the captured image. [0003] An angular velocity sensor and a position sensor are usually installed in the camera device, so as to respectively detect the angle change data and the position change information of the camera device during the movement period, and generate corresponding sensing signals. Angular velocity sensors, s...
