the Analysis of productivity and speed of the device of restoration of the image

The analysis of productivity of the developed device of restoration of the image real time is spent taking into account time harakyoteristik separate elements of the offered device according to a series mikyoroshem TTL 1533 [51-53].

The table of time delays of elements of a series 1533 is resulted in section 4.2, table 4.1.

On the basis of table 4.1 and drawings 4 we will make tables, and grayofiki dependences of an operating time of each of blocks and the device as a whole from the permission of an initial shot.

In drawing 4.23 dependence of processing time izobrazheyonija by the block of primary restoration from the shot permission is presented. Design data are resulted in table 4.12.

From the data resulted in the table it is visible, that the offered device does not allow to spend restoration in a real time of the image foryomata 1080р. For decrease of time expenses it is offered to use dubyolirovanie devices with work in phase opposition clock pulse. The alternative dubyolirovanija is represented in drawing 4.26. Time responses of machining of a shot are resulted by the doubled device of restoration of the image in table 4.16.

The optimised device of restoration from the shot permission

On the data resulted in drawing 4.27 and in table 4.16, it is possible sdeyolat a leading-out, that the cascade of two devices of restoration of the image dostayotochno for machining in a real time of shots a size to 1920х1080 pikyoselej.

Also the comparative analysis of time expenses apparatyonoj implementation of the offered method and algorithms with analogous ustrojyostvom has been made. Results of comparison of restoring time of the image predstavyoleny in table 4.17

Table 4.17. Comparative characteristics of restoration of a shot

The developed device 0,0098 c. (102 fps) 0,0196 (51 fps) 0,0397 (25 fps)

From table 4.17 follows, that at a hardware representation vosstanovleyonija images the developed method requires from 0.0098 to 0,0397с in zayovisimosti from its size that allows to raise efficiency of operations of restoration by increase in productivity to 4 times in comparison with the device-analogue.

Thus, the purpose of dissertational research in a part povysheyonija efficiency of operations of restoration of the image is attained.
