Description

Digital camera and MP3 playing device with USB controller

Technical field

The utility model relates to a kind of digital camera and MP3 playing device of the USB of having controller, particularly relates to a kind of digital camera and MP3 playing device that connects access USB memory storage.

Background technology

The digitized epoch, be full of panoramic digital product on the market, from powerful computing machine, the PDA (Personal Digital Assistant) emphasizing to be convenient for carrying, can promptly clap the digital camera of promptly seeing or the mobile phone of mobile communication is provided, also or the scanner of file scan can be provided, it promptly is that data processed result all is to store with the e-file of numeral that one common characteristics are all arranged, and can be with the data long preservation, repeat to read or do other utilization.

Along with personal computer is more and more universal, the pattern acceptance that camera combines with the MP3 player improves, demand by digital camera (DSC) picked-up image, picture promotes rapidly, digital camera has become present consumer and has wanted most one of computer peripheral equipment of buying, and known on the market digital camera utilizes photosensitive coupling component (Charge Coupled Device; CCD) or complementary matal-oxide semiconductor (Complementary Metal-Oxide Semiconductor; CMOS) photosensory assembly is an electrical signal with the optical image data shift signal, is responsible for control I/O interface, JPEG image processing, data compression and store recording on internal memory through digital signal processor (DSP).

MP3 (MPEG Audio Layer3) be a kind of be the efficient compress technique that realizes under the prerequisite with the high-fidelity.It has adopted special data compression algorithm that original sound signal is handled, the size that makes the digital audio file only is original 1/10th, and the quality of music does not have any variation, almost approach the quality of CD disc record, so the MP3 player also is the audio player that used by people on the market.

Be commonly called as the carry-on internal memory of thumb on the market, utilize the interface of USB transmission structure for the transmission data, now become the necessity of general computing machine user data backup, the floppy disk disc of relatively passing by (Floppy Diskette) capacity is many greatly, therefore, also can be used in general multimedia application, as the use of MP3 audio file, digital camera (DSC) image data access backup.

Yet the transmission of known digital camera and MP3 player data, it is host-guest architecture pattern by main frame end commander, the transmission of its data or reception all need connect main frame and be controlled by main frame, and the carry-on internal memory with data backup function also needs the control by main frame end commander, and can't be directly and digital camera or MP3 player do the data access.

Summary of the invention

Fundamental purpose of the present utility model is to provide a kind of digital camera and MP3 playing device of the USB of having controller, makes the carry-on internal memory with USB transmission structure can directly be connected also access data with the utility model.

In order to achieve the above object, the utility model provides a kind of digital camera and MP3 playing device of the USB of having controller, comprising: a digital camera module, in order to capture extraneous image; One MP3 playing module is in order to processing audio signal and broadcasting; One first controller is connected in this digital camera module and this MP3 playing module, in order to the control and treatment digital signal; One second controller is connected in this first controller, in order to control the access of USB memory storage data; And a USB interface, be connected in this second controller, in order to external this USB memory storage; Thus, the utility model can connect this USB memory storage and do the transmission access of data.

In order to enable further to understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet appended graphic only provide with reference to and the explanation usefulness, be not to be used for the utility model is limited.

Fig. 1 connects the stereographic map of USB memory storage for the utility model;

Fig. 2 is a circuit block diagram of the present utility model;

Fig. 3 is the circuit block diagram of digital camera module; And

Fig. 4 is the circuit block diagram of MP3 playing module.

Embodiment

Fig. 1 connects the stereographic map of USB memory storage for the utility model, the utility model is digital camera and the MP3 playing device 1 with USB controller, be connected with extraneous USB memory storage 2 via usb 14, and this USB memory storage 2 carry-on internal memory that is the USB transmission structure.

Fig. 2 is a circuit block diagram of the present utility model, and the digital camera of the USB of having controller of the present utility model and MP3 playing device 1 comprise first controller 10, second controller 12, internal memory 13, usb 14, LCD, digital camera module 16 and MP3 playing module 18.

Please in conjunction with Fig. 2, Fig. 3 is the circuit block diagram of digital camera module, this digital camera module 16 comprises image sensor 161 and analog/digital converter 162, by the extraneous image of image sensor 161 acquisitions, with the optical image data shift signal is analog image signal 163, convert analog image signal 163 to digital image signal 164 via analog/digital converter 162 again, be the digital image file of digital camera (DSC) image data.By first controller 10 this digital image file is temporary in the internal memory 13, this internal memory 13 can be flash memory (Flash Memory), and when the extraneous image of acquisition, can watch the extraneous image that will capture by LCD 15.

Please again in conjunction with Fig. 2, Fig. 4 is the circuit block diagram of MP3 playing module, this MP3 playing module 18 comprises MP3 code translator 181, digital/analog converter 182 and earphone jack 183, the MP3 audio file that MP3 code translator 181 will be deposited in internal memory 13 via the 10 commander's controls of first controller is deciphered processing, and send sound signal to digital/analog converter 182 and do signal kenel conversion, be connected with external earphone by earphone jack 183 then, and sound signal is sent to earphone, and make the people be heard the sound of the sound signal of MP3.

Please consult Fig. 2 again, this second controller 12 connects first controller 10 and usb 14, it is a USB2.0 0TG controller, it can accept the control of first controller 10, and control linkage is in the USB memory storage 2 (seeing also Fig. 1) in usb 14 external worlds, the MP3 audio file of USB memory storage 2 will be deposited in, digital camera (DSC) image data is sent to internal memory 13 of the present utility model, it also can accept the control of first controller 10, and the MP3 audio file in the internal memory 13 is deposited in control, digital camera (DSC) image data is sent to extraneous USB memory storage 2 (seeing also Fig. 1) via usb 14, and then reach the function of access data, and do not need just can directly do the access of data with extraneous USB memory storage 2 via main frame.
