Embodiment
The pick-up unit that the embodiment of the present invention provides, computing machine and detection method, first according to the non-image information (infrared signal of object in surveyed area, the temperature information etc. of object) judge in surveyed area, whether have object to exist, when judging have object to exist in surveyed area, in order to make testing result more accurate, again judge in surveyed area, whether have object to exist according to the image information in surveyed area, when again judging have object to exist in surveyed area, the mode of operation of computer system is switched to the lower mode of operation of a power consumption, thus can probability of miscarriage of justice be reduced, and effectively can save the power consumption of computer system.
Before the explanation carrying out embodiments of the invention, several concepts that first simple introduction is relevant to the embodiment of the present invention.
Computer system has two kinds of mode of operations usually, and one is normal mode of operation, and one is non-normal mode of operation, and wherein, non-normal working pattern comprises again screen saver mode and sleep pattern.
The several modes defined below by ACPI (AdvancedConfigurationandPowerInterface, the ACPI) power management of computing machine illustrates the implication of normal mode of operation and non-normal working pattern:
S0 pattern: all parts in computing machine are all in normal operating conditions, and now, computer system is in normal mode of operation;
S1 pattern: CPU quits work, now, except passing through cpu clock controller by except CPU closedown, the miscellaneous part in computing machine is still in normal operating conditions;
S2 pattern: CPU closes, and now, CPU is in the state of decommissioning, and cpu clock controller is also closed, but the miscellaneous part in computing machine is still in normal operating conditions;
S3 pattern: the miscellaneous part except internal memory is all in the state of decommissioning, also referred to as STR (SuspendtoRAM suspends to internal memory);
S4 pattern: memory information write hard disk, all parts are all in the state of decommissioning, and also referred to as STD (SuspendtoDisk suspends to hard disk), now, system primary power cuts out, but hard disk is still charged and can be waken up;
S5 pattern: computing machine is in closed condition, all parts Close Alls (comprising power supply) in computing machine.
Computer system is called that computer system is in sleep pattern when being in S1, S2, S3, S4 and S5 pattern.
So-called screen saver mode is computer system when not receiving any operation in official hour, shows the pattern of the multimedia messagess such as the picture that prestores or animation over the display.
As can be seen from foregoing description, under S0 to S5 pattern, the power consumption of computer system consumption reduces successively, and under screen saver mode, and the power consumption of computer system is greater than the power consumption of computer system under sleep pattern.
In addition, because under screen saver mode, graphoscope shows the multimedia messages prestored, under S3, S4 and S5 pattern graphoscope close, security when therefore computing machine is under those non-normal working patterns be greater than computing machine be in normal mode of operation under security.
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.

Wherein, described detecting unit 101 is for obtaining the non-image information in surveyed area; Described image acquisition unit 102 is for obtaining the image information of described surveyed area; Described first judging unit 103, for according to described non-image information, judges whether have object to exist in described surveyed area, to obtain the first judged result; When described second judging unit 104 does not have object for indicating in described surveyed area in described first judged result, according to the described image information that described image acquisition unit 102 obtains, judge whether have object to exist in described surveyed area, to obtain the second judged result; Described first control module 105 does not have object for indicating in described surveyed area in described second judged result, and computer system is current when being in the first mode of operation, control described computer system and be switched to the second mode of operation, power consumption when described computer system is in described first mode of operation is greater than the power consumption that described computer system is in described second mode of operation.
Object in above-described embodiment typically refers to human body, can by detecting the non-image information in surveyed area, judge whether human body leaves surveyed area (being also whether have human body to exist in surveyed area), when judging that human body leaves surveyed area, in order to make testing result more accurate, again according to the image information in surveyed area, judge whether human body leaves surveyed area, when again judging that human body leaves described surveyed area, the mode of operation of computer system is switched to the lower mode of operation of a power consumption.
Due to user in front of a computer time, computer system is in normal mode of operation usually, when user leaves computing machine, then computer system can be switched to non-normal working pattern, to save the power consumption of computing machine, meanwhile, under screen saver mode or some sleep patterns, can also ensure that the content on graphoscope is not passed by seeing of people, improve the security of computer system.Therefore, following examples, be all normal mode of operation with described first mode of operation, described second mode of operation is non-normal mode of operation is example, is described the display device of the embodiment of the present invention.
Described detecting unit 101 can be the plurality of devices whether existed for human body.
For example, described detecting unit 101 can be a pyroelectric infrared sensor, for obtaining the infrared signal of the human-body emitting in surveyed area, the advantage of described pyroelectric infrared sensor is to be merely able to human body, can avoid the interference of other non-human barrier.Described first judging unit 103 can judge whether have human motion in surveyed area according to the change of described infrared signal, and now, the non-image information in the described surveyed area in above-described embodiment refers to the infrared signal of human body.
Whether, based on foregoing description, the first judging unit 103 in above-described embodiment can also comprise: mobility detect unit, for according to described non-image information, detect in described surveyed area and have object to move; Performance element, during for having object to move in described mobility detect unit inspection to described surveyed area, obtain indicating the first judged result having object to exist in described surveyed area, when not having object to move in described mobility detect unit inspection to described surveyed area, obtain indicating in described surveyed area the first judged result not having object.
Another example is, described detecting unit 101 can also be a microwave remote sensor, and for obtaining the microwave signal of the human-body emitting in surveyed area, according to described microwave signal, described first judging unit 103 can judge in surveyed area, whether someone exists.Now, the non-image information in the described surveyed area in above-described embodiment refers to the microwave signal of human body.
Another example is, described detecting unit 101 can also be a light sensor, and for obtaining the light information in surveyed area, according to described light information, described first judging unit 103 can judge in surveyed area, whether someone exists.Now, the non-image information in the described surveyed area in above-described embodiment refers to light information.
Certainly, described detecting unit 101 can also for other all for detecting in surveyed area the equipment whether having object to exist, illustrate no longer one by one at this.
The scope of the surveyed area in above-described embodiment is normally determined by the correlation parameter of described detecting unit 101, such as, when described detecting unit 101 is pyroelectric infrared sensor, the scope of described surveyed area is determined by the sensitivity of described pyroelectric infrared sensor.User can adjust the scope of described surveyed area by the relevant parameter of the described detecting unit 101 of adjustment.
For example, under normal circumstances, when user normally uses computing machine, and the distance of graphoscope is between 40cm to 70cm, when the distance of user and display is greater than 70cm, usually show that user is away from computing machine, therefore, the relevant parameter of described detecting unit 101 can be adjusted, make its surveyed area be set to centered by described detecting unit 101, radius is 70cm, and angle is the sector region of 80 degree.Be illustrated in figure 2 the schematic diagram of the default sensing region of the embodiment of the present invention.
In Fig. 2, described detecting unit 101 is installed on the display of described computing machine, is understandable that, described detecting unit 101 can also be installed on any suitable location place of described computing machine.
Described image acquisition unit 102 can be the image capture devices such as a camera, camera, described image acquisition units 101 also can be installed on any suitable location place of described computing machine, under normal circumstances, be installed on the display of described computing machine, to obtain the image information of described surveyed area.
Non-image information in the surveyed area that above-mentioned first judging unit 103 obtains according to described detecting unit 101, judge in surveyed area, whether have object to exist, when judging have object to exist in surveyed area, trigger described second judging unit 104 again according to the image information of the surveyed area of described image acquisition unit 102 acquisition, judge in surveyed area, whether have object to exist.When described first judging unit 103 judges do not have object in surveyed area, then continue, according to the non-image information in the surveyed area of described detecting unit 101 acquisition, to judge in surveyed area, whether have object to exist.
In addition, for the purpose of accurately, described first judging unit 103 can show in testing result: all do not have object to deposit in case in surveyed area in predetermined lasting time (such as 3 seconds), then draw in surveyed area the judged result not having object.
Mention in foregoing, when described first judging unit 103 judges have object to exist in surveyed area, described second judging unit 104 will be triggered again according to the image information of the surveyed area of described image acquisition unit 102 acquisition, judge in surveyed area, whether have object to exist, when described second judging unit 104 judges have object to exist in surveyed area, trigger described first control module 105, thus described first control module 105 computer for controlling system adjusts to the second mode of operation from the first mode of operation.When described second judging unit 104 judges do not have object in surveyed area, that is, during the getting the wrong sow by the ear of described first judging unit 103, then trigger described first judging unit 103 and continue, according to the non-image information in the surveyed area of described detecting unit 101 acquisition, to judge in surveyed area, whether have object to exist.
Concrete, described second judging unit 104 by modes such as recognitions of face, can judge whether have object to exist in surveyed area.
In above-described embodiment, can when judging that human body leaves surveyed area, computer system is switched to non-normal working pattern, to save the power consumption of computer system, in addition, conveniently user uses, can also after computer system be switched to non-normal working pattern, continue to detect described surveyed area, when detecting that user turns back to described surveyed area, then computer for controlling system switches back normal mode of operation from non-normal working pattern.
Concrete, when described computer system is in non-normal working pattern, whether can continue to detect in described surveyed area by described detecting unit 101 has object to exist, when detect have object to exist in described surveyed area time, control described computer system and switch back normal mode of operation.
When computer system is in sleep pattern, the CPU in computing machine does not work, now, also just cannot the image that described image acquisition unit 102 obtains be processed, therefore, when computer system is in sleep pattern, do not adopt described image acquisition unit 102 to detect described surveyed area.
But, when described computer system is in screen saver mode, CPU in computing machine normally works, therefore, it is possible to process the image that described image acquisition unit 102 obtains, that is, when computer system is in screen saver mode, described image acquisition unit 102 can be adopted to detect in described surveyed area be.But, when adopting described image acquisition unit 102 to detect in described surveyed area, CPU needs to process image in real time, take larger cpu resource, do not reach the object of saving power consumption, therefore, under normal circumstances, when computer system is in non-normal working pattern, described image acquisition unit 102 can not be adopted to detect described surveyed area.
Based on foregoing description, as shown in Figure 3, described pick-up unit can also comprise: the second control module 106, described first judged result for obtaining at described first judging unit 103 indicates in described surveyed area has object to exist, and described computer system is current when being in described second mode of operation, controls described computer system and be switched to described first mode of operation.
In addition, for the purpose of accurately, described first judging unit 103 can show in testing result: have object to deposit in case in surveyed area in predetermined lasting time (such as 3 seconds), then draw in surveyed area the judged result having object to exist.
When computer system is in non-normal working pattern, most parts in computing machine are all in off-position, under non-normal working pattern, in surveyed area object still can be detected in order to make described computer system, and computer for controlling systematic evaluation returns normal mode of operation, described pick-up unit also comprises: supply module, for when described computer system is in described second mode of operation, for described detecting unit and described second control module are powered.
