(4) embodiment: following the specific embodiment of the present invention is elaborated:
A kind of method that keeps viewing distance by human body sensing and televisor, human body sensing device is set on televisor, this human body sensing device is connected with the central microprocessor of televisor by interface circuit, its Control Software is made amendment, promptly program is made amendment and replenish, also can be understood as increases human-induced signal's control program, and program is write in the microprocessor CPU chip, and the I/O interface of definition microprocessor is human-induced signal's input interface.Specify (or a plurality of) I/O pin, in microprocessor, set response sighting distance predetermined value, also can carry out the setting of the first response time T1, the second response time T2; Can also carry out the first protection sighting distance L1 and the second protection sighting distance L2, the setting of the first response time T1, the second response time T2; Can also carry out the setting of setting, the setting of standby response time and the Auto Power On response time T3 of standby sighting distance; In the induction range of distance in human body sensing device of human body and human body sensing device, produce signal; provide signal via interface circuit for central microprocessing unit; it is characterized in that utilizing microprocessor that this change in signal strength is discerned, handled; compare with response protection sighting distance predetermined value; control the user mode of televisor according to the result; it is at least a state in the picture effect, sound effect, light-emitting caution effect of televisor; in response sighting distance predetermined range, change normal operating condition, thereby obtain information warning.Above-mentioned response sighting distance predetermined value can have different changing values, and it can select to set in advance by operation push-button on the televisor or telepilot.Televisor can be provided with light-emitting caution device, by central microprocessor control, via driving circuit, makes to be attached thereto to connect to such an extent that the LED luminotron is lighted, and different control methods or driving circuit can be realized different effects.
Operation by function key that predetermined value is set, the predetermined value data message is provided with, it can be " predetermined value setting " project in " the sighting distance function " that increases during menu shows, comprise " response sighting distance ", " response time " content, operation by respective keys " enters " or " withdrawing from " setting, this function key can be on the TV set panel or the keypress function that increases newly on the telepilot causes, also can be volume increasing-and-decreasing key (V+/V-) or channel increasing-and-decreasing key (CH+/CH-) or direction operating key (on/down and a left side/right side) or the appointment function of other buttons in software, by operation to above-mentioned button, after the numerical value of predetermined value or strong and weak data message set, the data of setting are stored, when central processing unit has induced signal by the induction installation transmission, from storer, call.In assignment procedure, can also have the operation of definite meaning, comprise opening (ON) or closing (OFF) and set of sighting distance function, or through the default setting behind the appropriate time.In the process of setting, during the menu of increase showed, the response sighting distance can be from the numeric representation of 0-9 rice, also can be far away, far away, suitable (or safety), nearer, near hint expression or default data setting.The response guard time can be second, branch, the time numeric representation; also can be hint expression or the default data setting of long period, long-time, suitable (or safety) time, short time, short period, also can be slow, slow, suitable (or safety), soon, very fast hint expression or default data setting.
In adjustment project process with predetermined value correction calibration function, undertaken by the adjustment program, operation by respective keys " enters " or " withdrawing from " adjustment project, it can be the adjustment project in " the sighting distance function " that increases in the menu, it also can be the adjustment project under the maintenance adjustment modes, by this function key can be on the TV set panel or the keypress function that increases newly on the telepilot, also can be that volume increasing-and-decreasing key (V+/V-) or channel increasing-and-decreasing key (CH+/CH-) or direction operating key (on/down and a left side/right side) or other are pressed the appointment function in software, by operation to above-mentioned button, numerical value or increase and decrease adjusting are re-entered in the operation of button, parameter to predetermined value is adjusted, and adjusted new argument stored, when reusing, call new argument, subdue because the deficiency of inductor component self performance, or because environmental impact (as temperature). the duty that unfavorable factors such as maintain and replace cause is inaccurate, produce negative consequences such as offset error, make it return to desirable duty.
When carrying out above operation, also need increase display subroutine shows, for the operation of button each time, i.e. key position information each time, handle via central microprocessing unit identification, show on screen by the driving of screen display control display circuit, carry out the demonstration of content of operation, comprise demonstrations such as menu demonstration, the demonstration of catalogue bar, numerical value and information-change.
The contents of a project that further also can be brightness, colourity, color saturation, tone, contrast, acutance, aspect ration example, freeze frame, movie theatre display mode, standby mode, menu bases such as width of cloth type on increase at 16: 9.Further, it can also carry out the selection of controlling object, as brightness, colourity, color saturation, tone, contrast, acutance, aspect ration example, freeze frame, movie theatre display mode, standby mode, 16: 9 width of cloth types etc.
In carrying out screen display OSD application, the effect of character display, display icon, display highlighting, display image can be the television image with the viewing area in showing, carries out blanking, obtains clear effect; Also can be television image, not carry out blanking, obtain Overlay the viewing area.
Because pyroelectric infrared sensor is not high to mobile response sensitivity longitudinally, can take following measure: 1, increase inductor quantity, adopt the even number mode, installing the employing symmetric mode, comprise symmetry, left-right symmetric up and down; 2, because the doppler type ultrasonic inductor has higher sensitivity to moving longitudinally, these two kinds of inductors can be arranged to orthogonal state in the use, also be the compound inductor of two, three, four sensing elements that infrared inductor and ultrasonic sensing device can be combined.
Inductor component and the lens or the optical filter that cooperate with it are the ingredient of induction installation.
Geometric configuratioies such as that Fresnel optical lens or the lens that are used to respond to, optical filter can be designed to is square, circle.
Interface circuit can adopt extended mode, increases the I/O interface of microprocessing unit, should not be too much but occupy the interface amount.
Realization of the present invention, also can be to be carried out by the discrete component beyond the CPU element: the control bit that is connected circuit such as luminance channel in the televisor, chrominance channel, contrast passage, color saturation passage by testing circuit, decision circuitry, control circuit, delay circuit be controlled, when detection signal reached predetermined range, the level that has control circuit to produce was controlled the control bit of respective channel circuit.
Method of the present invention can be applied to video equipments such as computer monitor equally, utilizes former machine hardware and software to make amendment and replenish, and can carry out same control, also can be to be realized by aforesaid discrete component.
