Image zoom can be switched between 1x, 2x, 4

electronic zoom. FOV switchover and electronic zoom both are used for deflating or magnifying

the image. Nevertheless, 1x and 4x are realized by changing multiplying factor through built-in

two sets of IR optical lenses. 2x and 8x are done by electronic zoom. Fig.7-2 shows images with

different multiplying factors.

Its original multiplying factor is

again to get 4x zoom, and then 8x zoom in. It will change to 1x if pressing “Z’ for the fourth time.

So, it is a circulatory process.
