Above-mentioned steps S2 and step S3 are mainly the hand-off process while pressing for the first Navigational button button.Judged whether to need to carry out the function of this shift knob in conjunction with present mode by the first decision circuitry.Be navigation mode if current, do not need switching; If current, be the night vision pattern, the first Navigational button button is pressed exactly for the night vision pattern is converted to navigation mode.
Above-mentioned steps S2 and step S4 are mainly the hand-off process while pressing for the first night vision switch button.Be the night vision pattern if current, do not need switching; If current, be navigation mode, the first night vision switch button is pressed exactly for navigation mode being converted to the night vision pattern.
Further, when navigationsystem enters the night vision pattern, the relevant parameter of night vision pattern can be set on the read-out of navigationsystem, adjust the mode of operation of night vision system.Be brightness or the photo-equilibrium adjustment of night vision picture, the focusing of camera, swing etc.
In like manner can obtain the changing method of night vision system, as shown in Figure 3, it comprises step:
S11, open night vision system, the night vision system handover module carried out to initialization, enter the night vision pattern, the night vision video signal cable by the camera collection of night vision system to the night vision video signal transmission to night vision system, shown.
S22, the real-time use state of detector switch button, when shift knob being detected and press, whether the shift knob that judgement is pressed is the second Navigational button button: if it is perform step S33; Otherwise, execution step S44.
By the use state of the real-time detector switch button of the second button testing circuit, whether there is shift knob to be pressed, which shift knob what press is.
S33, judge whether the pattern of current night vision system is navigation mode: if it is keep present mode, do not switch; Otherwise, current night vision pattern is switched to navigation mode, the navigation vision signal by the camera collection of navigationsystem to the navigation video signal transmission to night vision system, shown, night vision system enters navigation mode.
S44, confirm that the second night vision switch button is pressed, judge whether the pattern of current night vision system is the night vision pattern: if, keep present mode, do not switch; Otherwise, current navigation mode is switched to the night vision pattern, the night vision vision signal by the camera collection of night vision system to the night vision video signal transmission to night vision system, shown, night vision system enters the night vision pattern.
Judged whether to need to carry out the function of this shift knob in conjunction with present mode by the second decision circuitry.After carrying out above-mentioned switching, further, when night vision system enters navigation mode, the relevant parameter of navigation mode can be set on the read-out of night vision system, adjust the mode of operation of navigationsystem.
Should be understood that, application of the present invention is not limited to above-mentioned giving an example, and for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection domain of claims of the present invention.
