Embodiment
See also the 2nd, 3 figure, the 2nd figure is the sketch map of the present invention's hand-held device, and the 3rd figure is the flow chart of step of electricity saving method of the present invention's hand-held device.
Hand-held device 10 comprises display 11, image capturing element 12, input element 13, answers key 14, housing 15 and circuit board 16.Circuit board 16 is provided with processor 161 and memory element 162, and processor 161 is electrically connected at image capturing element 12, and memory element 162 can be taken an image in advance via image capturing element 12; And the image store that will photograph becomes in memory element 162 and builds people's ear image in one; Certainly the source of building people's ear image in being somebody's turn to do also can be via arbitrary external electronic (for example: computer, PDA, UMPC; Mobile phone) input is not to be defined in 12 of image capturing element to catch.Mainly can comprise on the housing 15 and receive words portion 151, conversation face 152, image capturing element 12, input element 13 and display 11; Wherein input element 13 generally can be made up of a plurality of physical button; In practice; Answer key 14 can be said a plurality of physical button wherein one, must not be defined in the input element 13 but answer key 14, it can be arranged in any suitable position on the housing 15 (indicating in figure).And image capturing element 12 generally can be camera, but not subject to the limits.When a conversation incident takes place in hand-held device 10; It can comprise and receives an incoming call or dial a call conversation; And when processor 162 is judged conversation incident generation and is carried out call function; Processor 162 activation image capturing element 12, image capturing element 12 is then caught the image arround the hand-held device 10, and with this image that captures with before be stored in the memory element 162 within build people's ear image and do identification; And based on of the brightness of this identification result with control display 11; Comprise more that wherein the key 14 of answering that touches on the hand-held device 10 by the user opens image capturing element 12 with incoming call answering, and the brightness of so-called control display 11 can comprise the brightness of turning down display 10 or directly will close display, reaches the effect of power saving with the consumed power that reduces whole hand-held device 10.Certainly, the brightness of display 11 is mainly determined by backlight module, but Protector that the present invention desires, as long as the brightness that display sent can cooperate above-mentioned other necessary element and variation to some extent by image capturing element 12, all in the present invention's protection category
It should be noted; Image capturing element 12 must be located on the one side together of hand-held device 10 with conversation face 152; When hand-held device 10 during near the user; Image capturing element 12 just can capture the image arround the hand-held device 10, and in order to identification with judge this image that captures is built people's ear image in whether meeting.
Below the flow process of the step of the electricity saving method of explanation hand-held device can combine to consult the 2nd, 3 figure, when a conversation incident takes place; Hand-held device 10 can get into an answer mode (receiver mode); Touch input element 13 and the activation image capturing element 12 of hand-held device 10 by the user, when the ear of hand-held device 10, utilize the image capturing element of being located on the conversation face 152 12 to catch the image arround the hand-held device 10 near the user; Then; In a preset period of time, come this image of identification whether to meet to be stored in to build people's ear image in one in the memory element 162 through processor 161, when in the image that captures meets, building people's ear image; The processor 161 that is disposed on the circuit board 16 can send a signal; Turning down even to close the brightness of display 11,, then after preset period of time, turn down even close the brightness of display 11 through this signal if build people's ear image in can't the identification image in preset period of time whether meeting.
It should be noted; If hand-held device 10 is in answer mode (receiver mode), then carry out abovementioned steps, if hand-held device 10 is in hands-free answer mode (hand-free receiver mode); Then based on the setting of hands-free answer mode brightness with control display 11; Wherein, under hands-free answer mode, hand-held device 10 can turn down the brightness of display automatically or cut out display in the conversation back in a preset period of time.Certainly, the brightness of so-called control display 11 then as stated, purpose reaches the effect of power saving with the consumed power that reduces whole hand-held device 10
The 4th figure is the sketch map of another embodiment of the present invention's hand-held device.See also the 4th figure; The overall construction design of hand-held device 20 roughly is same as the 2nd figure; Exist together mutually and repeat no more; Not existing together then is, the display 21 of hand-held device 20 of the present invention is a touch-sensitive display, and the virtual button of answering of the touch that input element 24 can be on the touch-sensitive display to be appeared.
Can know by above-mentioned explanation; When the conversation incident took place, the electricity saving method of hand-held device of the present invention can just be located at the image capturing element capturing video on the hand-held device through script, and in whether this image of processor identification meets, builds people's ear image; If build people's ear image in image meets; Can confirm the user under talking state, turn down or close display brightness this moment can't influence operation, more can reach the effect of power saving.Because the electricity saving method of hand-held device of the present invention is to control display brightness through the mode of the software design of relation of interconnecting between above-mentioned hardware element and power management, therefore can avoid operating in the conventional art problem of inconvenience and the raising of element cost.
The above person of thought; Be merely the present invention's preferred embodiment; When the scope that can not limit the present invention's enforcement with this, promptly change and modification according to claim of the present invention and the simple equivalent done of invention description generally, all still belong in the scope that patent of the present invention contains.Arbitrary embodiment of the present invention in addition or claim must not reached whole purposes or advantage or the characteristics that the present invention discloses.In addition, summary part and title only are the usefulness that is used for assisting the patent document search, are not the interest field that is used for limiting the present invention.
