In the embodiment of the present invention, it can be stochastic generation that host side generates the mode of synchronous code, or, host side can also generate synchronous code according to default a certain rule, is not construed as limiting herein.
202, according to the synchronous code preset-image scanning order correspondence relationship information, according to the image scanning order corresponding with the synchronous code received, each pixel on imageing sensor is scanned；
In the embodiment of the present invention, pre-set synchronous code-image scanning order correspondence relationship information, this synchronous code-image scanning order correspondence relationship information indicates each order of the image scanning corresponding to the synchronous code being likely to occur, when view data scaning treatment device receives after the synchronous code of host side, namely can determine that the image scanning order corresponding with the synchronous code received according to default synchronous code-image scanning order correspondence relationship information, according to the image scanning order corresponding with the synchronous code received, each pixel on imageing sensor is scanned afterwards.
Step 202 is specifically referred to the description in Fig. 1-a illustrated embodiment in step 102, repeats no more herein.
203, carry out scrambling as the view data that scanning is obtained, obtain the diagram data after scrambling；
Wherein, the scrambled code used in above-mentioned scrambling processes is that above-mentioned host side is known.
In the embodiment of the present invention, scrambling refers to that treating scrambled data with a pseudo-random code sequence (i.e. scrambled code in the embodiment of the present invention) is multiplied, to treat the process that scrambled data is encrypted, specifically, by scrambled code, view data is carried out scrambling, the view data that scanning obtains is carried out the process of scrambling and is referred to the realization of existing signal scrambling technique by view data scaning treatment device, repeats no more herein.
In embodiments of the present invention, so that the scrambled code used in above-mentioned scrambling processes for above-mentioned host side it is known that the embodiment of the present invention provide the following two kinds implementation:
In one implementation, view data scaning treatment device utilizes the view data that above-mentioned scanning is obtained by above-mentioned synchronous code to carry out scrambling, namely, view data scaning treatment device directly utilizes the view data that step 202 scanning obtains by the synchronous code that step 201 receives and carries out scrambling, owing to synchronous code is to be issued by host side, therefore, as long as agreement view data scaning treatment device uses the synchronous code that issues of the host side view data to scanning to carry out scrambling, the scrambled code that host side is apparent from step 203 scrambling processes using.
In another kind of implementation, above-mentioned synchronous code is carried out data mapping by the first data mapping algorithm preset by host side, obtain scrambled code (for ease of distinguishing, the scrambled code generated by host side is described as scrambled code A), in step 203, view data scaning treatment device first passes through the second default data mapping algorithm and above-mentioned synchronous code is carried out data mapping, obtain scrambled code (for ease of distinguishing, the scrambled code generated by view data scaning treatment device is described as scrambled code B), the view data that scanning is obtained by recycling scrambled code B carries out scrambling, obtain the view data after scrambling.Wherein, above-mentioned second data mapping algorithm is identical with above-mentioned first mapping algorithm or there are mapping relations, S2 states synchronous code carries out data so that stating the first data mapping algorithm by S2 and maps the scrambled code (i.e. scrambled code A) that obtains with by above-mentioned second data mapping algorithm, above-mentioned synchronous code to carry out the scrambled code (i.e. scrambled code B) that data mapping obtains consistent.Owing to be ensure that scrambled code A and the concordance of scrambled code B by this mechanism, therefore, the scrambled code used in host side known steps 203 scrambling processes is equivalent to.
204, the view data after above-mentioned scrambling is transferred to above-mentioned host side, above-mentioned host side carries out correspondingly unscrambling and reduction treatment to the view data after above-mentioned scrambling；
