In one embodiment, the image capturing device 1 comprises a voice command input unit 10, a voice command controlling chip 20, a storage unit 30, an image capturing unit 40, and a display unit 50. The image capturing device 1 may be a digital camera, a camera phone, a PDA, or any other digital products with image capturing functions. The voice command input unit 10, the storage unit 30, the image capturing unit 40 and the display unit 50 are electronically connected with the voice command controlling chip 20.
The voice command input unit 10 is configured for receiving one or more voice commands inputted by users. Each of the one or more voice commands may be a standard voice command or a common voice command of a user. The standard voice command are usually pre-recorded by the voice command input unit 10, and stored in the storage unit 30. The voice command input unit 10 may be a microphone, a recorder, or any other electronic devices that may record voice commands. It may be understood that a user may be a manufacturer of the image capturing device 1, or a buyer of the image capturing device 1. If the standard voice commands are inputted by the manufacturer or other users, a user may listen to a record of the standard voice commands, so as to control pronunciation when speaking to the image capturing device 1 for inputting a common voice command. For example, a standard voice command may be “take a photo” or “take three photos consecutively.” Then, if the user wants the image capturing device 1 to take a photo one time, the user may speak “take a photo” to the voice command input unit 10. If the user wants the image capturing device 1 to take 3 photos consecutively, the user may speak “take three photos consecutively” to the voice command input unit 10.
The voice command controlling chip 20 comprises a plurality of functional modules (detailed description is given in FIG. 2), and is configured for setting a voice command identification standard for the common voice commands of any user. The voice command controlling chip 20 is further configured for determining whether a common voice command satisfies the voice command identification standard, and generating a controlling command according to the common voice command if the common voice command satisfies the voice command identification standard.
The storage unit 30 is configured for storing the standard voice commands and the voice command identification standard. Furthermore, the storage unit 30 is configured for storing images captured by the image capturing unit 40. Depending on the embodiment, the storage unit 30 may be a read only memory (ROM), an electrically erasable, programmable, read only memory (EEPROM), a random access memory (RAM), or any other kind of memory.
The image capturing unit 40 is configured for capturing one or more images according to the controlling command. In one embodiment, the image capturing unit 40 may comprise a lens, a transducer, such as a charge coupled device (CCD), and other elements (not shown in FIG. 1).
The display unit 50 is configured for displaying the images captured by the image capturing unit 40. The display unit 50 may be a liquid crystal display (LCD).

In the illustrated embodiment, the voice command controlling chip 20 comprises a setting module 210, a voice command information storing module 220, a voice command information analyzing module 230, and a controlling module 240. The modules 210, 20, 230, 240 may be used to execute one or more commands for the controlling chip 20.
The setting module 210 is configured for setting the voice command identification standard for the common voice commands. In one embodiment, the voice command identification standard defines a similarity degree between characteristics of any common voice command and the characteristics of a corresponding standard voice command. For example, the similarity degree may be set as 40%. The characteristics of a voice command may comprise a frequency, amplitude, a volume and a pulse width of the voice command. In one embodiment, if the similarity degree between each characteristic of a common voice command and each corresponding characteristic of a corresponding standard voice command is more than or equal to 40%, the common voice command is regarded as the standard voice command.
The voice command information storing module 220 is configured for storing the voice command identification standard and the standard voice commands into the storage unit 30.
The voice command information analyzing module 230 is configured for analyzing the characteristics of a common voice command received from the voice command input unit 10, and comparing the characteristics of the common voice command with the characteristics of each of the standard voice commands, so as to determine if the common voice command satisfies the voice command identification standard. If the common voice command satisfies the voice command identification standard, the voice command information analyzing module 230 determines that the common voice command is the standard voice command, and generates a controlling command according to the common voice command.
The controlling module 240 is configured for controlling the image capturing device 40 to perform a corresponding operation according to the controlling command, such as taking one photo or taking three photos consecutively.
FIG. 3 is a flowchart of one embodiment of an implementation method of an image capturing device with a voice command controlling function. Depending on the embodiment, additional blocks may be added, others removed, and the ordering of the blocks may be changed.
In block S10, the voice command input unit 10 receives standard voice commands inputted by a user. It may be understood that the user may be a manufacturer of the image capturing device 1, a buyer, or any other valid owners of the image capturing device 1. In one embodiment, a standard voice command may be a pronunciation of “take a photo” or a pronunciation of “take three photos consecutively” spoke by the user.
In block S12, the setting module 210 sets a voice command identification standard for common voice commands of any user. In one embodiment, the voice command identification standard defines a similarity degree, e.g., “40%,” between characteristics of any common voice command and the characteristics of a corresponding standard voice command. It may be understood that the characteristics comprise a frequency, amplitude, a volume and a pulse width of the voice command.
In block S14, the voice command information storing module 220 stores the voice command identification standard and the standard voice commands into the storage 30.
In block S16, the voice command input unit 10 receives a common voice command input by a user. For example, the voice command input unit 10 receives a voice command of “take one photo” input by the user.
In block S18, the voice command information analyzing module 230 analyzes the characteristics of the common voice command, and compares the characteristics of the common voice command with the characteristics of each of the standard voice commands stored in the storage unit 30. In step S20, the voice command information analyzing module 230 determines if the common voice command satisfies the voice command identification standard according to the comparison result. In one embodiment, the voice command information analyzing module 230 determines if the similarity degree between each characteristic of the common voice command and each corresponding characteristic of any standard voice command is more than or equal to 40%. If the common voice command satisfies the voice command identification standard, the procedure goes to block S22.
In block S22, the voice command information analyzing module 230 generates a command according to the common voice command. In block S24, the controlling module 240 controls the image capturing device 40 to perform a corresponding operation according to the command, such as taking one photo.
