Abstract: A method for adjusting a shooting condition of a digital camera through motion detection is applied to determine a shooting parameter of the digital camera. The adjusting method includes the following steps. At least two consecutive images, namely a first pre-capture image and a second pre-capture image, are selected. The first pre-capture image and the second pre-capture image are divided into a plurality of selection blocks. A motion vector of each selection block is calculated. The motion vector of each selection block is used to generate a background dominant motion vector of the camera sloshing and a self-movement vector of the shot object. The background dominant motion vector is subtracted from the self-movement vector of the shot object, so as to obtain a corrected foreground motion vector. According to the size of the corrected foreground motion vector, the corresponding shooting parameter is determined.

Abstract: A method for automatically shooting a panoramic image by a digital image pickup device is described. In the method, a pixel error value between a real-time image and an alignment image overlapped with each other is continuously compared and calculated. When the pixel error value is smaller than a preset threshold value, the digital image pickup device is automatically driven to shoot a second image to be stitched and blended with a previous image into a panoramic image. The shooting of the panoramic image is simplified by using automatic image capturing.
