Embodiment Construction

[0037] The present invention is applied to electronic devices with image processing, such as personal computers, digital video cameras, digital cameras and other electronic devices. However, it should be noted that the present invention is not limited to the above examples, and is only described here. In addition, in the present invention, multiple continuous images are obtained, and the motion vector in each image is analyzed. Then determine the degree of camera shake and the movement of the subject from the motion vector. According to the shaking and movement of the two, determine the corresponding shooting conditions. In order to clearly illustrate the operation of the present invention, two consecutive preview images are used as an illustration below, but it is not limited thereto. Please refer to figure 2 As shown, it is a schematic diagram of the operation flow of the present invention. The following are the operation steps of the present invention:

Abstract

The invention discloses a method for adjusting shooting conditions of a digital camera by utilizing motion detection, which is used for determining shooting parameters of the digital camera according to the sway of the digital camera or a shot subject when the digital camera is used for shooting a digital image. The method for adjusting the shooting conditions of the digital camera includes the steps as follows: selecting two continuous images, namely a first pre-shoot image and a second pre-shoot image; dividing the first pre-shoot image and the second pre-shoot image into a plurality of selected blocks; calculating the motion vector of each selected block; generating the background main motion vector of the sway of the camera and the self motion vector of the shot subject according to the motion vector of each selected block; obtaining the motion vector of a corrected foreground after subtracting the background main motion vector from the self motion vector of the shot subject; and determining the corresponding shooting parameters according to the size of the motion vector of the corrected foreground.

Description

technical field [0001] The invention relates to a method for adjusting shooting conditions of a digital image, in particular to a method for adjusting shooting conditions 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 traditional film camera or a digital camera, the user's grasp of the camera is often 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 d...
