Abstract
The utility model discloses and aims at providing a digital camera with the USB host machine expanding function, which is convenient for use, has the function of a USB host machine and can carry out reading/writing operations of USB equipment. An internal electronic circuit of the digital camera is arranged in a machine shell, a USB interface is arranged on the machine shell, a starting host machine expanding mode pin which can carry out specified settings is arranged on a DSP module in the internal electronic circuit of the digital camera, and a power supply output pin of the DSP module is connected with the DC power supply input end of the USB interface. The starting host machine expanding mode pin is arranged on the DSP module of the digital camera; therefore, the OTG function of a USB port of the digital camera can be realized by the setting of electrical potential of the pin; meanwhile, as main equipment, the digital camera can read data from an SD card and an internal memory space of the digital camera itself, and write the data into the switched-in USB attached equipment, thereby enhancing the convenience of the digital camera.
Description
Technical field
The utility model relates to a kind of digital camera, in particular, relates to the digital camera of the main frame expanded function of a kind of USB of having.
Background technology
Digital camera is development propagation at a terrific speed since coming out, and the luxurious camera of making over enters common people house.Digital camera users is through outdoor common use of the tourism way neutralization of being everlasting, the picture that the several people takes a group photo together and taken the other side respectively often appears, situation about need share magazine photo, and the work that copies photograph mutually will be used computer usually, to wait until generally speaking go back home separately in after, just can carry out.If have the people to carry notebook computer during tourism, then need to start notebook computer and copy, use very inconvenient.And the USB interface of existing digital camera only limits to as slave unit, by using main equipments such as computer, printer to the read-write of camera internal memory and storage card, to simple functions such as battery charge, and function singleness.
The utility model content
The utility model is in order to overcome weak point of the prior art, to provide a kind of digital camera that can make to have the usb host function, can carry out the read-write operation of USB device, the convenient digital camera that uses.
The utility model is achieved through the following technical solutions:
A kind of digital camera with main frame expanded function of USB, in casing, be provided with digital camera internal electron circuit, it is characterized in that, casing is provided with USB interface, DSP module in the described digital camera internal electron circuit is provided with the startup main frame mode of extension pin that can carry out specific setting, and the power supply output pin of described DSP module is connected with the dc supply input of USB interface.Wherein, can be after setting to starting main frame mode of extension pin by software setting for using or need not.
The utlity model has following technique effect:
The DSP module of digital camera of the present utility model is provided with and starts main frame mode of extension pin, by setting to this pin current potential, be used to realize OTG (the on the go) function of digital camera USB port, make digital camera both can be used as the USB slave unit, can make again digital camera as main equipment from itself memory headroom and the SD card reading of data and it is write in the USB slave unit of access, increase the convenience of digital camera.Make things convenient for everybody out of doors or intercourse the photograph that camera is separately taken in the travelling way, and avoid carrying redundant equipment, make the relaxation and happiness more of travelling.
Description of drawings
The circuit theory diagrams of the digital camera of the main frame expanded function that Fig. 1 has a USB for the utility model is a kind of.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
The circuit theory diagrams of the digital camera of the main frame expanded function that Fig. 1 has a USB for the utility model is a kind of, in casing, be provided with digital camera internal electron circuit, casing is provided with USB interface, DSP module in the described digital camera internal electron circuit is provided with the startup main frame mode of extension pin (USBID pin) that can carry out specific setting, and the power supply output pin of described DSP module (USBPWREN pin) is connected with the dc supply input of USB interface.By the current potential that starts main frame mode of extension pin (USBID pin) is set, can start the OTG pattern, make digital camera use as usb host.Under the OTG pattern, power supply output pin (USBPWREN pin) then is activated the direct voltage that 5v is provided to outside slave when inserting USB device, and the outside slave of USB is powered, and finishes the condition enactment that DSP drives external equipment.In the present embodiment, described startup main frame mode of extension pin is set to ground connection.
USB OTG function is by digital camera software systems software set, to guarantee that when not using the OTG function, the USB interface of digital camera is under the setting of slave unit, avoids the digital camera waste of electric quantity.When USB device inserted, the user set the mode of operation of choosing a digital camera.When being set at general modfel, power supply output pin (USBPWREN pin) is set to low level, output voltage not, and USB device is as slave unit, and the DSP module of digital camera can only be with picture-storage in USB device.When using the OTG pattern, power supply output pin (USBPWREN pin) is set to high level, output 5v voltage is powered to USB device, digital camera is as main frame, the DSP module from digital camera itself memory headroom and the SD card reading of data and it is write in the USB slave unit of access.Whilst on tour, a digital camera and the Portable USB equipment such as USB flash disk that client often uses that has the usb host expanded function of the present utility model is arranged, just can make things convenient for everybody out of doors or intercourse the photograph that camera is separately taken in the travelling way, and avoid carrying redundant equipment, make the relaxation and happiness more of travelling.
