Abstract
The invention provides a display screen device use state judgment method and circuit. When a display screen device enters a preset working mode, circuit timing starts, and when the timing duration reaches the timing interval duration of the preset working state, a camera is started; image information collected by the camera is identified, whether the relevant information of the human face exists in images or not is judged, and in this way whether a user uses the screen or not is judged; if it is judged that the user is using the device, judgment is ended, and next judgment is waited for; if it is judged that no user is using the device, a CPU controls a system to enter a standby mode after storing the site, the screen is made to be turned off, and the time interval is changed into the timing interval under the standby state. According to the display screen device use state judgment method and circuit, whether the user is using the screen device or not is judged at set intervals, if the user is using the device, the operation state is kept; otherwise, the system enters the dormant state so as to save power consumption.
Description
[technical field]
The present invention relates to determination methods and circuit that whether a kind of display device is in using state.
[background technology]
Along with the arithmetic capability of mobile electronic device is increasing, resolution of screen and refresh rate more and more higher, the equipment in working order interior power consumption consumed of lower unit interval also improves rapidly, and the battery technology of mobile device does not significantly develop, this service time just causing mobile electronic device is fewer and feweri, and usual every day all will charge.Reading, surf the Net, watching video is the most important application scenarios of mobile electronic device, and being the scene that electric quantity consumption is maximum, if way can be had when not affecting Consumer's Experience effectively to reduce the working time of these scenes, will be significantly work.
Method common at present pre-sets a dormancy time, when not having user to operate in the time that duty continues, then equipment entered dormant state.The bad place of this method is, if user continues to use, then must carry out some useless operations at set intervals to allow equipment maintenance work to allow equipment not carry out dormancy, bringing very large redundant operation and bad Consumer's Experience like this to user; Or when the auto sleep time is longer, user has left but equipment time that still will by the time arrange just enters dormancy, waste the energy so also in a large number.
Therefore the present invention proposes a kind of batch (-type) using state determination methods, by at set intervals to whether there being user using equipment to judge before screen, if have user in use, keep running status, otherwise enter dormant state immediately to save power consumption, then between rest period, observation User Status is still kept, after waiting for that user returns, recover equipment state when user leaves at once.
[summary of the invention]
One of the technical problem to be solved in the present invention, be the determination methods that a kind of display device using state is provided, before at set intervals to screen, whether there is user using equipment to judge, if have user in use, keep running status, otherwise enter dormant state immediately to save power consumption, then between rest period, still keep observation User Status, after waiting for that user returns, recover equipment state when user leaves at once.
