Embodiment
As shown in Figure 1: realize that with this invention relevant hardware mainly contains microprocessor, memory, digital signal processor DSP, Voice decoder, LCD display, camera, keyboard, Mike and loud speaker.During acquisition of image data, need the extraneous data of camera collection and give DSP transfer of data, DSP is presented at data on the LCD display by relevant register is set, DSP will change the value of related register when receiving the beginning record command, the beginning acquisition of image data also stores in the built-in buffer area of DSP, relies on DSP, camera, LCD display three to realize alternately for collection, broadcast, the demonstration of view data.Wherein dsp chip is brought into play central role, can directly control LCD display, be delivered directly to the data in the DSP buffer area in the LCD buffer area and display image data, the mutual of DSP and other modules then controlled and coordinated to the ModemCPU interface, makes the whole software orderly function.When gathering voice data, need Mike or band Mike's earphone to gather the external sound data and be sent to power amplification circuit, analog signal is converted to digital signal through A/D converter, by noise suppression and automatic gain control circuit, in encoder, carry out the voice digital signal coding, when playing sound data, decoder carries out tone decoding to the voice digital signal that receives, through automatic gain control circuit, be sent to D/A converter and be converted to analog signal, through power amplification circuit, from loud speaker or earphone, play out sound.Memory Controller Hub be responsible for view data and voice data in the memory storage, read and operation such as deletion, memory has ROM read-only memory and RAM random access memory, RAM is as buffer.Wherein microprocessor adopts the chip of the MSM5100 of Qualcomm model, and sound coder is the variable rate voice codec, adopts the chip of QDSP2000 model.
As shown in Figure 2: for the flow process of program in view data and the voice data gatherer process, step is as follows: the user sends the instruction of beginning image data by KeyEvent, digital signal processor DSP is provided with its register according to user instruction, and initialization, sound relevant program simultaneously reinitializes, photographing module begins acquisition of image data, send the instruction notification sound module simultaneously and begin to gather voice data, in the image data process according to the time clock correction come regularly to be provided with graph data station location marker and voice data station location marker, for example, the station location marker that the view data of gathering in 0 to 5 second is set is 1, and the view data of gathering in 6 to 10 seconds station location marker is set is 2.This view data station location marker is corresponding one by one with the station location marker that collects voice data, and the station location marker of gathering voice data in promptly 0 to 5 second is 1, and the voice data setting of gathering in 6 to 10 seconds is designated 2.The image data process finishes then to stop data collection the image that collects, voice data and station location marker data is kept in the memory.
As shown in Figure 3, the program step of synchronously playing images data and voice data is as follows: the user sends the beginning play instruction by KeyEvent, photographing module can read corresponding view data according to choosing of user in the storage device, voice data and relevant position are identified in the interim buffering area, after data read finishes, respectively view data and voice data are sent to the buffering area of digital signal processor DSP buffering area and voice decoder, DSP register and initialization sound interface are set, then begin playing image data and voice data as success, view data shows on display, voice data broadcasts by loud speaker, in the process of data playback, if the station location marker of current image date changes, whether whether the station location marker that will judge voice data so identical with the station location marker of current image date, if the identical station location marker as view data and voice data of station location marker all is 2, the value that then only changes station location marker continues to play, if station location marker is inequality to be 2 as the view data station location marker, and the voice data station location marker is 1, then when changing station location marker, upgrade voice data, reach the synchronous of view data and voice data.
