Specific embodiment

It is practical new to this below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer Type is described in further detail.

As shown in figs. 1-7, embodiment provided by the utility model, a kind of two-way camera lens skin image capture means, including There are two-way image acquisition and processing unit and mobile terminal, two-way image acquisition and processing unit is mounted to described by way of bridge joint Mobile terminal；Two-way image acquisition and processing unit includes sensor U1, processing unit U2 and output unit P1；Sensor U1 is adopted The skin properties collected are transferred to processing unit U2, send data to mobile terminal by output unit P1.Output unit P1 For usb connecting port, image information is transferred to external equipment by usb connecting port.

The utility model uses the identical sensor U1 of two hardware configurations, but uses different software procedures, to realize Different functions.

Sensor U1 is the COMS image chip of 5,000,000 pixels, model MI5100.Processing unit P1 includes DSP core Piece；Dsp chip model SN9C5259AFG.

Probe power filter circuit includes capacitor C2, capacitor C3, capacitor C4, capacitor C5, capacitor C6, capacitor C7, electricity Hold C8 and capacitor C9.Capacitor C2, capacitor C3 and capacitor C4 parallel connection provide filter circuit, capacitor C5, capacitor C6 for DOVDD power supply Filter circuit is provided for VDDA_SEN power supply with capacitor C7 parallel connection, and capacitor C8 and capacitor C9 provide filter circuit for DVDD power supply.

Chip power filter circuit includes capacitor C15, capacitor C16, capacitor C17, capacitor C18, capacitor C19, capacitor C20, capacitor C21, capacitor C22 and capacitor C23.Capacitor C15, capacitor C16, capacitor C17, capacitor C18 and capacitor C19 parallel connection are VDD33 power supply provides filter circuit.Capacitor C20, capacitor C21, capacitor C22 and capacitor C23 parallel connection provide filtering for VDD12 power supply Circuit.
