The input/output control system that is used for cell phone (or other mobile devices) according to the present invention has prevented that button press unintentionally from activating cellular illumination, demonstration and other functions.Cell phone can be forbidden some function automatically based on environment and external factor, and described environment and external factor include but not limited to user's position, the moment and surround lighting.
For example, button press unintentionally generally can take place when cell phone is stored in pocket or wallet more continually.Surround lighting in the shell such such as pocket or wallet is generally less than other local surround lightings.Cell phone sense ambient light of the present invention, and surround lighting during less than threshold value disable button push.Cell phone can be forbidden other functions during other operating condition NOR operation conditions.For example, cell phone can be forbidden illumination and/or show when the user talks by cell phone.
In general, display screen comprises inside and outside display screen and display screen (for example LCD) and keyboard back light, and it has consumed a large amount of battery electric powers.Like this, prevent that unintentionally button press and demonstration and activation backlight from can save energy and increasing cellular battery life.
With reference now to Fig. 1,, wherein shows the exemplary embodiment of realization according to the cell phone 10 of input/output control system of the present invention.Those skilled in the art will appreciate that the cell phone that can use other types.Cell phone 10 comprises telephone control module 12, power supply 14, memory 16, memory device 18 and cellular network interface 20.Cell phone 10 can comprise wave point and associated antennas 24, microphone 26, the output of the audio frequency such as loud speaker and/or output plughole 28, display screen 30 and the user input device 32 such as keyboard, some optional equipment, voice-activated and/or other input equipments such as WLAN interface 22.Display screen 30 can comprise inner display screen and exterior display screen.For example, flip-type and clam shell cell phone can comprise main inner display screen and visible exterior display screen when cell phone is closed.
With reference now to Fig. 2,, the exemplary embodiment of cell phone 10 comprises camera module 50.Camera module 50 comprises the camera lens 52 that is exposed to surround lighting 54.Camera module 50 sense ambient light 54 (promptly determining the rank or the intensity of surround lighting 54) also generate signal 42.In other words, signal 42 is based on the intensity of surround lighting 54.Signal 42 also can indicate the change rate of strength of surround lighting 54.
Like this, I/O control module 60 has prevented that the user from importing other functions (for example preventing that the user from importing 32 and making a call) of 32 activation display screens 30 and/or startup cell phone 10.I/O control module 60 has prevented that also display screen 30 (comprising display screen and keyboard back light) from connecting (for example in pocket or wallet time) unintentionally repeatedly.I/O control module 60 can also be forbidden camera module 50 and take pictures to prevent camera module 50.(or additional) as an alternative, I/O control module 60 can be forbidden the button of control camera module 50.
I/O control module 60 can be waited for predetermined periods before any function of forbidding in the intensity decreases of surround lighting 54 after being lower than threshold value.For example, intensity may be because other factors and reducing temporarily, and not necessarily indicate cell phone 10 and be in pocket or the wallet.Like this, wait for before I/O control module 60 can or otherwise change the operation of cell phone 10 in any function of forbidding and expiring up to scheduled time slot.Only as example, this period can be 5 seconds.On the contrary, I/O control module 60 may be required in and makes cell phone 10 turn back to before the normal running intensity to increase to and be higher than threshold value and continue scheduled time slot.
I/O control module 60 also can be revised threshold value according to the variation of surround lighting 54.For example, when surround lighting 54 when persistent anomaly is high in a period of time, I/O control module 60 can increase threshold value.On the contrary, when surround lighting 54 persistent anomaly in a period of time low (but being not less than threshold value), I/O control module 60 can reduce threshold value.
At some indoor location, external condition can further be changed the operation of I/O control module 60.For example, indoor location may have the surround lighting less than threshold value, thereby I/O control module 60 may be forbidden the function (promptly when cell phone 10 is not in pocket or wallet) of cell phone 10 unintentionally.Here, the user can import 32 pairs of cell phones 10 via the user and programme, to prevent any function of I/O control module 60 forbiddings.
