DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The advantages and innovative features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

The present invention provides an automatic shooting method and a desirable digital image capturing devices thereof. The digital image capturing device can either be a digital camera or a digital camcorder; however, the present invention is not confined to these devices.

Please refer to FIG. 1, which illustrates a frame structure of a digital image capturing device of the present invention. As shown in FIG. 1, the digital image capturing device 10 comprises a processor 21, an image capturing module 22, a memory 23 and an indicating device 24, all of which are electronically coupled with each other. The image capturing module 22, the memory 23 and the indicating device 24 are controlled by the processor 21. The processor 21 is also used to perform image recognition and is capable of identifying dynamic or stationary images captured by the image capturing module 22. The image capturing module 22 can comprises elements such as a CCD or a CMOS for capturing dynamic or stationary images. The memory 23 stores an identification database 31 and the necessary application programs for the operation of the digital image capturing device 10. The identification database 31 is used to store the identification data, such as the predefined gestures, and these data are retrieved during the image recognition. The application of the identification database 31 will be discussed in detail in the subsequent section. The indicating device 24 is used to inform the user the automatic shooting process of the digital image capturing device 10, and the preferred indicating device 24 is a flashing device (for example, LED indicating light) or a beeping device; however, the present invention is not confined to these devices.

Refer to FIG. 2, which shows a flow chart of an automatic shooting method of the present invention.

First, the present invention proceeds with step 201: activating the automatic shooting process.

The user first needs to select an object and presses the automatic shooting button on the digital image capturing device 10 so as to activate the automatic shooting process. At the same instant, the digital image capturing device 10 can use the indicating device 24 to send out signals so as to inform the user that the automatic shooting process has been activated. The preferred indicating signal is flash light or beep, but the present invention is not confined to these signals.

The present invention then proceeds with step 202: capturing a gesture image.

In step 202, when the user moves to a predetermined position and makes a gesture predefined in the identification database 31, such as waving his/her or making specific hand motions (such as extending three fingers or making a V-shaped gesture), the image capturing module 22 of the present invention will then capture the image of such gesture.

The present invention then proceeds with step 203: performing an instant image recognition procedure.

After the image capturing module 22 captures the image of the user's gesture, the processor 21 then performs the instant image recognition procedure via the image recognition technology, and identifies the gesture image captured by the image capturing module 22.

The present invention then proceeds with step 204: determining whether the gesture image matches any specific gesture image predefined in the identification database. After the processor 21 successfully identifies the gesture image captured by the image capturing module 22, the processor 21 then determines whether the user's gesture image matches any specific gesture images predefined in the identification database 31. If the user's gesture image fits to a specific gesture predefined in the identification database 31, then the indicating device 24 will send out signals to inform the user and then proceeds with step 205. In a preferred embodiment of the present invention, the signals sent from the indicating device 24 during step 204 and step 201 are different, so the user can easily distinguish the difference between the two signals. If the processor 21 cannot identify the gesture image captured by the image capturing module 22 or if the user's gesture image does not correspond to any specific gesture images predefined in the identification database 31, the indicating device 24 will send out a different signal to inform the user, and the present invention will return to step 202 and recapture the user's gesture image.

The present invention then proceeds with step 205: waiting for a specific number of seconds.

In order to provide the user with enough time to make a chosen pose, after the image recognition is finished, the digital image capturing device 10 can delay a few seconds (for example, 5 seconds) before entering into the next shooting procedure. The length of the delay can be adjusted and is not confined to 5 seconds.

Last, the present invention then proceeds with step 206: executing a specific shooting procedure. After waiting for a specific number of seconds, the digital image capturing device 10 can execute a specific shooting procedure. Pay extra attention that in the present invention, different gestures can have different shooting procedures. For example, hand waving can activate the shooting procedure to take a single image, and extending three fingers can activate the shooting procedure to take three consecutive pictures. Furthermore, the present invention is capable of performing different shooting instructions of the digital image capturing device 10 by identifying the setting in the identification database 31. For example, by a specific user's gesture, the camera lens can be directed to zoom in or zoom out, or the flash light can be activated; thus, the present invention is not confined to the aforementioned gestures and shooting procedures.

Although the present invention has been explained in relation to its preferred embodiments, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and the scope of the invention as hereinafter claimed.
