Method for taking a picture of a subject automatically in a digital camera

摘要

The present invention is to provide a method for taking a picture of a subject automatically in a digital camera including an image capturing unit, a CPU, a memory unit, a storage unit and a scanning program, comprising the steps of giving an image capturing instruction to the CPU for successively capturing images through the scanning program; causing the CPU to command the image capturing unit to successively capture at least a first image and a second image of a subject; storing the first image and the second image in the memory unit; causing the CPU to compare the first image and the second image by using the scanning program; generating an activating signal by the scanning program when contents of the first image and the second image are different; and causing the CPU to store the second image in the storage unit as the picture taken of the subject.
