second motor

42,43 at any time and microprocessor 51 is given in its location information passback, so that microprocessor 51 is judged the actual position of

motor

42,43.

Display module 6 also shows for the user after treatment in order to the original image signal that is received from photography assembly 4 outputs to be watched immediately, so display module 6 has an image-processing circuit 61 and a telltale 62.This routine telltale 62 is Liquid Crystal Display (LCD)s, and image-processing circuit 61 as shown in figure 15 is arranged in the box body 50 and electrically connect the integrated circuit of microprocessor 51 and camera lens 41, and it can carry out image processing to signal of video signal and be suitable for being passed to telltale 62 behind the signal that telltale 62 shows and show the surrounding environment picture to convert to.It should be noted that since image-processing circuit 61 be can use that present existing circuit reaches and widely person skilled in the art person know, so do not give unnecessary details at this.

According to preceding described, when the user passes through input block 53 input of control commands, then can be exporting in wired or wireless mode by output interface set 534 after the command code via the controller 532 of input block 53, after then signal converter 54 can receive this signal and this signal conditioning be become to be suitable for the signal and pressurization of microprocessor 51 receptions, behind the first wire transmission interface 543, cable and the second wire transmission interface 511, and be sent to the 512 pairs of signals of signal receiver and do suitably to adjust rear feed and go into microprocessor 51.Then, microprocessor 51 can order about first and

second motor

42,43 by motor drive unit 40 according to control command and rotate, and moves according to user's demand to make camera lens 41.

Hereinafter, each keypress function in the input element set 533 is described.

One, the effect of direction key group:

When the arbitrary button 5331 ~ 5334 in the direction key group is pressed, then can handle the corresponding code of output by via controller 532, then go into microprocessor 51 through output interface 534, signal converter 54, the second wire transmission interface 511, signal receiver 512 rear feeds in regular turn, because controller 532 can be compiled into each button different code signals and also store the corresponding codes table in the microprocessor 532, so in case microprocessor 532 receives that FD feed can discern easily is by which button input.So, when last key 5331 was pressed, then microprocessor 532 can rotate through motor drive unit 40 controls first motor 42 camera lens 41 is moved up along first direction 71, the also environment at high visual angle so that camera lens 41 can be photographed.When key 5332 was pressed instantly, then microprocessor 532 controls first motor 42 rotated camera lens 41 is moved down along first direction 71, so that the visual angle of camera lens 41 is also low.In the same manner, when left button 5333 or right button 5354 were pressed, then microprocessor 51 controls second motor 43 was along second direction 72 sway, the surrounding environment so that camera lens 41 can fully be photographed.In addition, because microprocessor 51 is to control first and

second motor

42,43 respectively, so also can be pressed simultaneously with a left side/

right button

5333,5334 because of last key 5331 and a left side/

right button

5333,5334 or following key 5332, microprocessor 51 is controlled first and

second motor

42,43 starts simultaneously, so that camera lens 41 no longer is defined on the axis of orientation and moves and can do omnibearing moving, with the abundant solution problem of visual dead angle in the past.

Two, the effect of other function keys 5335 ~ 5340:

At first explanation is, after

motor

42,43 starts, then positioning detector 55 can give microprocessor 51 returning about the location information after the rotation of

motor

42,43 immediately, so microprocessor 51 can be grasped the present position of

motor

42,43 immediately, and because microprocessor 51 has memory function (promptly having memory device), so can store these location informations, for follow-up use.

Automatic key 5335 is that correspondence one is by dealer or default camera lens 41 angles of user, be to store one group of

default motor

42,43 position in the microprocessor 51, so when the user pushes automatic key 5335, then microprocessor 51 can be controlled first and

second motor

42,43 rotations according to predeterminated position information, so that camera lens 41 moves to predetermined angle automatically.So, the user need each time not to need the button 5331 ~ 5334 of direction of passage key group to control camera lens 41 and moves to suitable angle, controls flow process and meets the hommization demand with simplification.

In addition, because under different users or the different situations, the visual angle that needs is difference to some extent, thereby present embodiment also has the function of self establishment demand angle, and also provides many group memory functions to come to set for the user in order to meet the different demands of user.So, when the user utilizes direction key group that camera lens is adjusted to an own desirable visual angle, then can push storage key 5336, then microprocessor 51 can preparation will with the relevant cached location information of camera lens 41 this moment, and button one

memory button

5338 or 5339 or 5340, after giving this location information one identification index, microprocessor 51 is again with this cached location information.So, utilizing storage key 5336 and memory button 5338 ~ 5340 collocation in this example, the user can store three default visual angles at most and represent with different memory button 5338 ~ 5340.

Then, when the user desires direct cutaway 41 to the visual angle of previous storage, then can push the memory button 5338 ~ 5340 that key 5337 and a correspondence are wished the visual angle that is written in the input block 53.So, 51 of microprocessors can capture the location information of corresponding memory button 5338 ~ 5340 and according to this first and

second motor

42,43 of location information direct control move to and wish the visual angle.So, the user can set required visual angle and can utilizing according to demands of individuals and be written into key 5337 and memory button 5338 ~ 5340 collocation, and cutaway is to wishing the visual angle fast, and then the diversified selection of user is provided and is convenient to user's operation.

According to preceding described, the utility model has following effect really:

1. camera lens 41 is omnibearing mobile:

Can only provide the camera lens of single direction axle (for example horizontal direction axle or vertical direction axle) to rotate compared to reverse image device in the past, because photography assembly 4 of the present utility model has two groups of

motors

42,43 that make camera lens 41 move respectively on

different directions

71,72, so the utility model can provide omnibearing angular field of view to select for the user, and then effectively reduce visual dead angle generation probability.In addition, because present embodiment utilizes the two groups of motor drive circuits 401,402 in the motor drive unit 40 to control first motor 42 and second motor 43 respectively, so microprocessor 51 can make two

motors

42,43 rotate simultaneously, make camera lens 41 not need to do in regular turn folk prescription and move, and then can reach the effect that adds the snapshot moving velocity to (for example first direction 71 or second direction 72).

2. processing ease:

Because the utility model provides automatic key 5335, the user only need key in single instruction can make camera lens 41 move to predeterminated position, and the many groups of collocation memory functions provide the user to store required any visual angle in advance, oversimplifies and the operation of hommization to provide.In addition, because this routine input media 53 can the order of wireless or wired mode transmitting control, cause input media 53 positions more unrestricted, so that the user controls.

Though it should be noted that the safety lever after photography assembly 4 in the previous embodiment is arranged at car, yet in fact it can be arranged at such as other positions of vehicle interior roof or back mirror or the like, should not be subject to the explanation of this paper.
