Moreover, the invention also discloses methods for realizing these applications.
Description
Technical field
The present invention relates to digital camera, particularly relate to a kind of multipurpose digital camera that has application program, it is except having static digital camera functionality and can be used as flash memory device or computer camera uses when joining with a computer in independent the use, this device also has some application programs relevant with above-mentioned functions can finish further derivation function, send and carry out video communication etc. as multimedia message, the present invention also relates to realize the method for those application in addition.
Background technology
Along with the continuous development of digital vedio recording technology, various digital vedio recording products have begun to enter in a large number huge numbers of families.Digital camera can convert the scenery that photographs to number format by inter-process and deposit in storage chip and needn't use film, and it can also be directly connected on computer, television set or the printer, even under certain condition, digital camera can also directly be linked on mobile telephone or the handheld computer.With respect to traditional camera, the advantage of digital camera is apparent, and therefore, it more and more is subjected to liking of people.
Corresponding to digital camera, computer camera based on same image taking technology has also produced great impact power in the multimedia application field, and it can connect functions such as machine realization video telephone, Web conference, dynamic video E-mail, computer shooting, picture editor, card making in conjunction with related software.
In addition, development along with data storage technology, the based semiconductor storage medium, such as flash memory (Flash Memory), the mobile storage means of art designs, fast, low in energy consumption with its writing speed, can plug at any time, removable, can store jumbo file and data, and do not need excellent performance such as specific mechanical device drives and become the main flow of mobile storage product day by day, as various plug type portable hard drives.Chinese patent application 02114882.1 " supporting the semiconductor memory method and the device of multiple interfaces " also discloses a kind of semiconductor memory method and device of supporting multiple interfaces, is used for data handling system.This semiconductor storage is equipped with the semiconductor storage medium module therein, and the interface module of the serial of controller module and at least two various criterions of support, parallel or wireless communication interface; By the interface of described various criterion, connect at least one data handling system to set up between described storage device and the described data handling system information exchanging channel based on serial, parallel or wireless communication interface with respective standard interface; Described storage device is by described interchange channel and described data handling system swap data.Described device provides the possibility of swap data file easily for the data handling system with distinct interface.Accompanying drawing 1 is its structured flowchart.
But, the function of above-mentioned these devices only is confined to use as a simple peripheral hardware storage device, perhaps simple digital camera uses, do not realize the combination of various functions, when need realizing different functions, the user just need different devices to finish respectively, this is not only very inconvenient, and has caused the waste on the cost.
Though occurred double mode digital camera in the prior art, it both can be used as digital camera and had taken the open air picture recording of taking pictures to, caught splendid moment and fragment, also can be used as computer camera, connected machine and realized dynamic camera function.But with computer camera and two kinds of purposes of plug type flash memory device carry out in conjunction with even and then with digital camera and above-mentioned two kinds of functions further combined with digital vedio recording still never occurred.
In addition, along with development of Communication Technique, multimedia message transmission and video communication also enter modern society's life day by day, if the user thinks the image that will take or is pre-stored in multimedia files such as image, music, animation and Flash in the digital camera to utilize multimedia message to send just need to install by other, the file that to want to send is sent to described device earlier, send then, this is very inconvenient; Moreover, the user wants carrying out video communication on available arbitrary the computer that can connect the internet at that time, its prerequisite is on this computer relevant video communication software to be housed in advance, otherwise just can't finish the operation of wanting, and load or download these application software from network temporarily all is extremely unpractical under many circumstances, and this has also caused sorry to the user.
