Embodiment Construction

[0039] Here, according to the method for detecting the stability of the digital camera device and the digital camera device of the present invention, software can detect whether the digital camera device is in a stable state, and then determine the shooting parameters of the digital camera device corresponding to the stable state of the digital camera device , such as: (but not limited by the present invention) sensitivity, shutter value and aperture value, etc. Here, the stable state of the digital camera device is determined by analyzing the variation of the subject's position in the multiple preview images captured in advance, and then the shooting parameters of the digital camera device are determined. Furthermore, it is also possible to further refer to the variable factors that affect the shooting effect, such as the state of the subject when shooting, the ambient brightness, and the hardware of the digital camera (for example, but not limited by the present invention: fl...

Abstract

The invention discloses a detection device for the stability of a digital video camera and a digital video camera. The detection method comprises the following steps: capturing a plurality of preview images at different time points; capturing a plurality of image blocks from at least one identical position of the preview images; calculating variation amounts of every two image blocks at the same position; comparing each variation amount with a displacement threshold; when all the variation amounts are equal to or less than the displacement threshold, judging whether the digital video camera is in a stable state; and when at least one variation amount is more than the displacement threshold, judging whether the digital video camera is in an instable state, and a group of corresponding shooting parameters is obtained according to the detection results of the stability.

Description

technical field [0001] The present invention relates to a shooting method, in particular to a method for detecting the stability of a digital camera device, which is used in a digital camera device, so that the digital camera device can detect its stable state through software, so as to adjust its shooting accordingly parameter. Background technique [0002] Today, with the rapid development of digital cameras, many people will use photography to record memorable moments. However, regardless of whether it is a film camera or a digital camera, it is often caused by the user's unstable grip on the camera, resulting in blurred images during shooting. As long as the camera is taken with bare hands, there will be more or less vibration problems. The difference is that the degree of stability of each person's hand is different, resulting in involuntary displacement when the shutter is pressed. Therefore, in order to avoid blurred images due to hand shake, digital camera manufac...
