Embodiment Construction

[0013] The image capture device of the present invention is used for photographing a target, and includes a processing unit, an image sensor and a storage unit. The processing unit is used for generating an ideal focus value when capturing the target. The image sensor is used for capturing an image frame with the target object. The image frame corresponds to an actual focus value. When the processing unit determines that the difference between the ideal focus value and the actual focus value is less than or equal to a first threshold value, the processing unit stores the image frame in the storage unit. The specific implementation is as follows.

[0014] Please refer to figure 1 , figure 1 It is a block diagram of an image capture device 100 according to a preferred embodiment of the present invention. The image capture device 100 takes a digital camera as an example, and includes a processing unit 110 , a stepping motor 120 , a focusing lens 130 , an image sensor 140 , a...

Abstract

The invention relates to a image processing method, which comprises: generating an ideal focusing value for picking an object; picking up a image picture including the object which corresponds with a real focusing value; comparing the difference between the ideal and real focusing value and the first door bank value; and saving the image picture while the difference is not larger than the door bank value. In the image processing method provided by the invention, that the difference is not larger than the door bank value means the image picture corresponding to the real focusing value is clear enough. Consequently, the method reduces product cost for it can realize the hand-shaking proof function without adding extra assembly.

Description

technical field [0001] The present invention relates to an image processing method and an image capturing device, and more particularly, to an image processing method and an image capturing device with anti-shake function. Background technique [0002] When using an image capture device such as a digital camera, the user often shoots blurry and unclear images due to hand shaking, which reduces the image quality. In order to reduce the problem of blurred images caused by digital camera shake, digital cameras usually have anti-shake function. Generally speaking, digital cameras currently on the market achieve the purpose of anti-handshake through optical anti-shake, electronic anti-shake or high-sensitivity anti-shake. [0003] Optical anti-shake is to adjust the imaging position by moving the position of the image sensor or using the movable lens to change the light path. However, such an optical anti-shake requires not only a rather sophisticated and complicated mechanical...
