Problems solved by technology

[0005] The piezoelectric component must be constantly driven by voltage in order to properly move the CCD to correct the image; however, the weight of the CCD component is heavier than that of a single lens, making it necessary to use a rather large piezoelectric component to drive the component
Although this method does not reduce the optical imaging quality of the lens, the bulky piezoelectric component increases the size of the camera with this function of correcting or suppressing hand vibration.

Said invention provides the connection mode of all the above-mentioned portions and the concrete working principle of said image sensing module.

Description

【Technical field】 [0001] The present invention relates to an image sensing module, in particular to an image sensing module that allows the image sensing unit to move in two dimensions. 【Background technique】 [0002] Such as figure 1 As shown, US Patent Publication No. 5266988 discloses an image vibration suppression device for a camera. The image vibration suppression device is arranged in the lens 32. When using the camera, the angular acceleration units 33p, 33y measure the angular acceleration information of the operator's vibrating camera, and provide a circuit to calculate and drive a group of driving components 37p, 37y. The components 37p and 37y move a lens in the lens 32 in the direction perpendicular to the optical axis to correct or suppress image blur caused by the operator vibrating the camera. [0003] However, driving the lenses in the lens to move in the direction perpendicular to the optical axis will reduce the peripheral brightness of the lens, and the...
