The specific embodiment
The present invention allows digital frame whether the people be arranged near can judging automatically, determining the mode of operation of itself, so as to when nobody's use digital frame or when having no talent nearby, is able to the control figure photo frame and enters battery saving mode, to reach effect energy-conservation, power saving.
Please refer to Fig. 1, be the embodiment calcspar of the digital frame of tool electricity-saving function of the present invention.As shown in the figure, present embodiment provides a kind of digital frame 1 of tool electricity-saving function, and it comprises: a timing unit 11, a sensing cell 12, a display unit 13, a processing unit 14, a system interface unit 15, a storage element 16 and a power supply interface 17.Wherein, timing unit 11 is in order to producing a timing signal, and sensing cell 12 is used for detecting an environmental aspect, to produce a sensing signal.
And sensing cell 12 can be for example infrared sensor (as: human body infrared sensor) or CIS in design.Wherein, if the words that design with infrared sensor, mainly be (as: to have the user close when producing a triggering signal confirming environmental aspect that digital frame 1 is put to change, can make human body infrared sensor be confirmed to take place environmental aspect changes, thereby when producing triggering signal), just can produce sensing signal.And if the words that design with CIS, then can obtain a signal of video signal earlier at the environmental aspect that digital frame 1 is put, and sensing cell 12 is further carried out an image algorithm and is come this signal of video signal of computing, with when confirming that this signal of video signal is people's image signal, the expression environmental aspect changes, so just export this sensing signal.Subsidiary one what carry is that whether the environmental aspect described in the present embodiment changes, is to understand because of using different sensors to have different results.
And display unit 13 for example is a display panels, in order to the image data that displays the play.16 of storage elements provide to the user and store the image data that institute's desire is play, and carry out the access use to offer processing unit 14.Wherein storage element 16 can for example be the arbitrary of non-volatility memorizer (as: flash memory (Flash Memory)), storage card or combination on actual design.
In addition, processing unit 14 more can further pass through a power control unit 141, carries out the power supply situation of each unit in the control figure photo frame 1 according to timing signal and sensing signal.And normally having the user and make under the situation that sensing cell 12 can sense nearby, processing unit 14 just can receive sensing signal, so just can work in a normal mode of operation by control figure photo frame 1, just carries out the playing video data smoothly.And it is opposite, if processing unit 14 is behind a special time of counting through this timing signal, there is no when receiving this sensing signal, just represent sensing cell 12 there is no detect near environmental aspect change, so processing unit 14 by power control unit 141 control of powering, makes digital frame 1 work in a battery saving mode equally.Wherein, this special time can for example be to be set at 5 minutes, that is when the time that surpasses 5 minutes, when sensing cell 12 does not all have the sensing signal of generation, processing unit 14 will be controlled and enter battery saving mode, the definite numerical value of this special time then can be the preset value that dispatches from the factory of digital frame 1 or be set up on their own by the user, just seldom be described at this.
And in the present embodiment, for convenience of description for the purpose of, power control unit 141 is as shown in Figure 1, in be built among the processing unit 14, with the usefulness of the control of powering as processing unit 14.Yet ability and technical staff should understand easily, and power control unit 141 can also be to adopt external mode to be connected in processing unit 14, the management of the aspect that powers with the control that receives processing unit 14.
In above-mentioned battery saving mode, the power supply control situation of processing unit 14 roughly has following mode: because display panels is the part that belongs to than power consumption in whole digital frame 1, therefore the most simple mode is exactly the power supply of closing display unit 13, and remaining is still in running order as sensing cell 12, processing unit 14 etc.So, when environmental aspect changes near sensing cell 12 detects, will produce sensing signal and give processing unit 14, allow processing unit 14 be controlled the power supply of unlatching again, to run on normal mode of operation to display unit 13.
Another kind of mode be can be the more further amount of saving energy, its design is when entering battery saving mode, processing unit 14 itself further can enter a closed condition.And because sensing cell 12, display unit 13 or even storage element 16 all are to be controlled by processing unit 14, so when processing unit 14 enters closed condition, can close the power supply to sensing cell 12, display unit 13 and storage element 16 etc. simultaneously.Thus, except can realizing closing the power supply to display unit 13, the power supply of all the other correlation units is also closed especially, in the hope of the amount of saving energy more.
And for the design of this battery saving mode, must relend and help timing unit 11, because it belongs to independent design, and itself have the characteristic that is operated in low power supply status.Make the timing unit 11 of this moment be able to, and further just producing an activation signal every a Preset Time (as: 2 seconds), to restart or wake up process unit 14 to processing unit 14 by design.Whereby, processing unit 14 just can and then be opened the power supply to sensing cell 12 again, to carry out environment measuring.Certainly, when the sensing cell 12 of this moment changed as if near environmental aspect still not detecting, then the time of counting owing to timing signal was still above this special time, so processing unit 14 will enter closed condition again.So repeat, environmental aspect changes and produces sensing signal to processing unit 14 near sensing cell 12 detects, and shows stored image data with control.
Moreover the system interface unit 15 in the digital frame 1 is to be connected in processing unit 14, and is used for externally connecting an application system (figure do not show) (as: computer), with as the signal transmission between digital frame 1 and application system.Power supply interface 17 then is to be used for receiving a civil power, and is changed and offer power-supply unit 141, with the power supply source as digital frame 1.Certainly, digital frame 1 is except being used as the required power supply of work by connecting civil power, when 1 of digital frame is connected in application system by system interface unit 15, also can receive power supply that application system provides, to carry out work by system interface unit 15.For example: system interface unit 15 is designs of adopting USB (USB) transport interface, then when digital frame 1 is connected with application system, just can receive 5 volts of voltages that application system provides, with as the required power supply of working.
In order to further specify detailed operation situation of the present invention, please continue with reference to the following description.In Fig. 2, be the embodiment flow chart of the electricity saving method of digital frame of the present invention.As shown in the figure, present embodiment provides a kind of electricity saving method of digital frame 1, and its step comprises: at first, start digital frame 1 (S201), and reset the counting (S203) of a timing signal.And after having reseted the counting of timing signal, after just Ji Shuo time makes zero, just can begin to carry out time counting (S205).
So, provide sensing cell 12 to come the testing environment situation, having or not change, and determine whether producing a sensing signal (S207) by near environmental aspect judging.If the judged result of step S207 is for denying, environmental aspect there is no change near then representing present digital frame 1, just can represent also that sensing cell 12 detects without any the user stops, thereby do not produce any sensing signal, whether arrive a special time (S209) so just directly confirm the counting of timing signal.
If the affirmation result of step S209, then repeats step S205 for not proceeding counting, and continues follow-up flow process; Opposite, if the affirmation result of step S209 is the words that are, then expression has arrived this special time, and in this section special time, the appearance that there is no any user is to allow sensing cell 12 produce sensing signal, so just can control power supply, so that digital frame 1 enters a battery saving mode (S211).And after digital frame 1 entered battery saving mode, sensing cell 12 wherein can be proceeded step S207 again and produce to have judged whether any sensing signal.
Then,, represent that then sensing cell 12 has the user to stop near detecting digital frame 1, change, thereby produce sensing signal and detect environmental aspect if the judged result of above-mentioned steps S207 is to be.Thus, digital frame 1 just can be controlled power supply, so that digital frame 1 enters a normal mode of operation (S213), this moment, digital frame 1 just can read image data, and plays this image data of demonstration smoothly and view and admire to the user.
Please, be the work embodiment flow chart of battery saving mode among the present invention more then with reference to figure 3.Present embodiment is at mentioned battery saving mode among above-mentioned Fig. 2 embodiment, further is illustrated workflow wherein, just can be considered further specifying among the step S211 in Fig. 2.As shown in the figure, after decision enters battery saving mode, at first close power supply (S301) to display unit 13.And on actual design, described at the design of battery saving mode as described above, can only design the power supply of closing merely to display unit 13, can continue afterwards to carry out the testing environment situation, to judge whether to produce sensing signal by sensing cell 12.
But present embodiment is to adopt more that the design of power saving illustrates, then after step S301, further make processing unit 14 enter a closed condition, and and then close power supply (S303) to sensing cell 12.Then, by the design of timing unit 11, to confirm whether arrive a Preset Time (S305).If confirm the result be, represent that then timing unit 11 is exported an activation signal and given processing unit 14, starting processing unit 14, and and then open power supply (S307) sensing cell 12.Thus, when the also out-of-work while of sensing cell 12, still can reach the effect that continues to detect by timing unit 11 at the enable signal that is produced every this Preset Time (time was shorter, as 2 seconds).In addition, if the affirmation result of step S305 for not the time, then still continues to confirm this Preset Time, till arriving this Preset Time.
At last, please refer to Fig. 4, be the Application Example schematic diagram of the digital frame of tool electricity-saving function of the present invention.Present embodiment is to describe with the actual state of digital frame 1 when working, shown in the left side among the figure, when digital frame 1 work, detection by sensing cell 12 has sensed the user and has stopped when viewing and admiring, will work in normal mode of operation, to come display image information by display unit 13.And when sensing cell 12 through behind the special time, does not all have the user of having sensed to stop, and when producing sensing signal, will be shown in the right among the figure, digital frame 1 can enter battery saving mode, the display unit 13 of this moment just can not show any image data yet.
In sum, the present invention increases in digital frame and has designed sensing cell, in order to the environment around the digital frame is detected, to have judged whether any user or people nearby.And then as the people nearby the time, allow digital frame can operate as normal playing photograph, and when nobody nearby the time, then allow digital frame enter battery saving mode.Whereby, allow digital frame under how need not make amendment complicated power circuit and thinking adopt situation than the element of power saving, can simply just realize having energy-conservation, purpose of power saving.
