Abstract

The invention discloses a method for adjusting the shooting setting of a digital camera by mobile detection, which is used for determining to adjust the shooting setting of the digital camera according to the vibration of the digital camera or the shaking of the shot object when the digital camera shoots a digital image. The adjusting method comprises the following steps: at least capturing two successive pre-shooting images; setting a central area and a boundary area on the same location of the pre-shooting images respectively; finding a characteristic point from the pre-shooting images; determining an area movement vector and a camera movement vector according the relationship between the characteristic point and the central area and the boundary area respectively; subtracting the camera movement vector from the area movement vector to produce an object movement object; and determining the adjustment of the shooting setting of the digital camera according to the maximum value one ofthe object movement vector and the camera movement vector.

Description

technical field [0001] The invention relates to a method for adjusting shooting settings of a digital image, in particular to a method for adjusting shooting settings of a digital camera by using motion detection. Background technique [0002] With the rapid development of digital cameras, many people use photography to record memorable moments. However, regardless of whether it is a film camera or a digital camera, it is often because the user's grip on the camera is unstable, resulting in blurred images when shooting. Because as long as the camera is held in hand, there will be more or less jitter problems. The difference is that the stability of each person's hand is different, resulting in involuntary displacement when the shutter is pressed. Therefore, in order to avoid blurring of captured images due to jitter, manufacturers of digital cameras correct blurred digital images through hardware or software. [0003] Different digital camera manufacturers have added diff...
