Embodiment
Fig. 1 illustrates the summary calcspar of the motion image detection circuit of the present invention's one correlation technique.Fig. 2 illustrates the summary oscillogram of the various signals of the motion image detection circuit of Fig. 1.Please refer to Fig. 1 and Fig. 2, in this example, motion image detection circuit 110 comprises frame count circuit 112 and dynamic decision-making circuit 114.Frame count circuit 112 is in order to export and write frame count value wr_cnt according to writing incoming frame instruction wr_cmd.Dynamically decision-making circuit 114 is coupled to frame count circuit 112, and carry out the arbitration circuit (do not illustrate) of output enable signal MQ_ON to motion image detection circuit 110 next stage according to writing frame count value wr_cnt, to allow this arbitration circuit determine accordingly whether the image displaying circuit (not illustrating) under motion image detection circuit 110 carries out dynamic play demonstration.
Particularly, in Fig. 2, frame clock signal CLK be for example in image displaying circuit in order to indicate each circuit blocks to operate at present the image duration at place, in this example, during the rising edge of two high level pulses, be an image duration.Image input data DATA_IN for example refers to the video data that image displaying circuit or motion image detection circuit 110 receive, and comprises packet DATA_N to DATA_N+3.React on writing of packet DATA_N to DATA_N+3, write incoming frame instruction wr_cmd write in packet fashionable for high level, otherwise be low level.Receive high level write incoming frame instruction wr_cmd time, frame count circuit 112 can increase write frame count value wr_cnt.Receiving low levelly while writing incoming frame instruction wr_cmd, frame count circuit 112 will can not be adjusted and write frame count value wr_cnt.Therefore, the frame count value wr_cnt that writes between packet DATA_N and DATA_N+1 is 1, and after packet DATA_N+1 writes, writing frame count value wr_cnt is 2, as shown in Figure 2.It should be noted, the frame count value that writes is herein since 0 counting.
In this correlation technique, an one dynamic mass observation form is defined as N image duration, and each dynamic mass to observe form be a constant offset N frame, wherein N=3.Taking Fig. 2 as example, i dynamic mass observation form 210_i of motion image detection circuit 110 comprises 3 image durations, and i+1 dynamic mass observation form 210_i+1 comprises 3 image durations, and wherein i is positive integer.And the end time point of i dynamic mass observation form 210_i is in fact the initial time point of i+1 dynamic mass observation form 210_i+1,3 frames of skew of meaning.The time span of other dynamic mass observation forms of this example and deflected length are when can by above-mentioned relation by that analogy, not repeating them here.
At the end time point of each dynamic mass observation form, be 2 if write frame count value wr_cnt, the enable signal MQ_ON that dynamically decision-making circuit 114 can be exported high level is accordingly extremely to arbitration circuit.The dynamic image number that this interval scale motion image detection circuit 110 detects has reached preset person, and therefore image displaying circuit is carried out dynamic play demonstration.In this example, dynamically the inner default critical count value of decision-making circuit 114 is M=2, and representative writes frame count value wr_cnt and exceedes at 2 o'clock, and dynamic play shows that operation can continue to be performed.Otherwise image displaying circuit can be left dynamic play and show.
In addition, in this correlation technique, corresponding to the window dimension signal win_s of dynamic mass observation form, its window dimension along with the increase of sequential, is sequentially 0,1,2, as shown in Figure 2 in each dynamic mass observation form.And at the initial time point of each dynamic mass observation form, it is 0 that window dimension all can be reset.Meanwhile, at the initial time point of each dynamic mass observation form, writing that frame count value wr_cnt also can be reset is 0, can not added up by frame count circuit 112 constantly.That is, at each dynamic mass observation form, the window dimension of window dimension signal win_s and write frame count value wr_cnt and restart to calculate.
Under this framework, the dynamic mass observation form of motion image detection circuit 110 is to be set as N, in each dynamic mass observation form, if detecting M frame, motion image detection circuit 110 has Regeneration dynamics data, while being N>M, image displaying circuit can start dynamic play demonstration.But in practical operation, if while having M+1 to upgrade frame in previous dynamic mass observation form, the current state of presentation video display circuit is to be in dynamic play to show.When the renewal frame in current dynamic mass observation form is while being less than M, image displaying circuit reaction that cannot be instant must just can be left dynamic play and show after the form of dynamic mass observation at present finishes.Therefore, the image displaying circuit of this framework is left dynamically to display the play and need to be waited for the more time, tends to waste unnecessary electric power.
Fig. 3 illustrates the summary calcspar of the image displaying circuit of one embodiment of the invention.Fig. 4 illustrates the summary calcspar of the motion image detection circuit of one embodiment of the invention.Fig. 5 illustrates the summary oscillogram of the various signals of the motion image detection circuit of Fig. 4.Please refer to Fig. 3 to Fig. 5, the image displaying circuit 300 of the present embodiment comprises motion image detection circuit 310 and arbitration circuit 320.Arbitration circuit 320 is coupled to motion image detection circuit 310.Motion image detection circuit 310 output enable signal MQ_ON are to arbitration circuit 320, to allow arbitration circuit 320 can determine accordingly whether image displaying circuit 300 carries out dynamic play demonstration.
Particularly, the motion image detection circuit 310 of the present embodiment comprises frame count circuit 312 and dynamic decision-making circuit 314.In each dynamic mass observation form, frame count circuit 312 is adjusted and is write frame count value wr_cnt according to writing incoming frame instruction wr_cmd, and output writes frame count value wr_cnt to dynamic decision-making circuit 314.In the present embodiment, each dynamic mass observation form comprises that an initial time point and finishes time point.For example, dynamic mass observation form 510_i comprises initial time point Pi_i and finishes time point Pf_i, dynamic mass observation form 510_i+1 comprises initial time point Pi_i+1 and finishes time point Pf_i+1, and dynamic mass observation form 510_i+2 comprises initial time point Pi_i+2 and finish time point Pf_i+2, wherein i is positive integer.
In the present embodiment, each dynamic mass observation form is defined as N image duration, wherein N=3, and each dynamic mass observation form is 1 frame of skew.Taking Fig. 5 as example, dynamic mass observation form 510_i, 510_i+1,510_i+2 comprise 3 image durations.And, in these dynamic mass observation forms, the end time point Pf_i of i dynamic mass observation form 510_i is between the initial time point Pi_i+1 of i+1 dynamic mass observation form 510_i+1 and finishes between time point Pf_i+1, and between the initial time point Pi_i+2 and end time point Pf_i+2 of i+2 dynamic mass observation form 510_i+2, as shown in Figure 5.End time point Pf_i+1, the Pf_i+2 of dynamic mass observation form 510_i+1,510_i+2 and the relation of other dynamic mass observation form can by that analogy, not repeat them here.In other words, the deviant of each dynamic mass observation form of the present embodiment is to be set as 1 frame.But the present invention is not limited to this, in other embodiments, the setting of deviant can be also 2 frames.In this kind of execution mode, taking Fig. 5 as example, now the end time point Pf_i of i dynamic mass observation form 510_i remains between the initial time point Pi_i+1 and end time point Pf_i+1 of i+1 dynamic mass observation form 510_i+1, but the end time point Pf_i of i dynamic mass observation form 510_i is before the initial time point Pi_i+2 of i+2 dynamic mass observation form 510_i+2.
Therefore, in summary, in exemplary embodiment of the present invention, if when each dynamic mass observation form is defined as N image duration, the setting of the deviant between each dynamic mass observation form can be 1,2,3 ..., or N-1 frame.In the above-described embodiments, because N is set as 3, therefore the setting of deviant can be 1 or 2, and its basis of design can be adjusted according to side circuit design requirement, and the present invention is not limited, and the embodiment of Fig. 5 to have be only to illustrate.
Then, continue referring to Fig. 4.Dynamically decision-making circuit 314 is coupled to frame count circuit 312.At the end time point of each dynamic mass observation form, if when writing frame count value wr_cnt and equaling pre-set count values M, dynamic decision-making circuit output enable signal MQ_ON to 320 arbitration circuit, to determine whether image displaying circuit 300 is proceeded dynamic play and shown, or leave dynamic play demonstration.Pre-set count values M is herein less than or equal to N, and M is nonnegative integer.
Specifically,, at the end time point of each dynamic mass observation form, if when writing frame count value wr_cnt and being M, the enable signal MQ_ON that dynamically decision-making circuit 314 can be exported high level is accordingly to arbitration circuit 320.The dynamic image number that this interval scale motion image detection circuit 310 detects has reached preset person, and therefore image displaying circuit 300 is proceeded dynamic play demonstration.In this example, dynamically the inner default critical count value of decision-making circuit 314 is M=2, and representative writes frame count value wr_cnt and exceedes at 2 o'clock, and dynamic play shows that operation can continue to be performed.Otherwise image displaying circuit 300 can be left dynamic play and show.
Taking i dynamic mass observation form 510_i as example, at initial time point Pi_i, packet DATA_N writes motion image detection circuit 310, what therefore frame count circuit 312 received high level accordingly writes incoming frame instruction wr_cmd, and increases accordingly the added up frame count value wr_cnt that writes.Therefore,, before receiving next packet DATA_N+1, the frame count value wr_cnt that writes being added up equals 1.Then, in the time that packet DATA_N+1 writes motion image detection circuit 310, what frame count circuit 312 received high level accordingly writes incoming frame instruction wr_cmd, and increases accordingly the added up frame count value wr_cnt that writes.Therefore,, before receiving next packet DATA_N+2, the frame count value wr_cnt that writes being added up equals 2.Therefore, at the end time point Pf_i of i dynamic mass observation form 510_i, the dynamic image number that dynamically decision-making circuit 314 can detect has reached default critical value M=2, and export accordingly the enable signal MQ_ON of high level to arbitration circuit 320, show to allow image displaying circuit 300 proceed dynamic play.
Again taking i+1 dynamic mass observation form 510_i+1 as example, at initial time point Pi_i+1, what frame count circuit 312 was added up writes frame count value wr_cnt is 1, and in the time that packet DATA_N+1 writes motion image detection circuit 310, what frame count circuit 312 received high level accordingly writes incoming frame instruction wr_cmd, and increase accordingly added up frame count value wr_cnt, the i.e. wr_cnt=2 of writing.Then,, owing to not having packet to write motion image detection circuit 310, therefore write incoming frame instruction wr_cmd in low level before receiving next packet DATA_N+2.According to the design architecture of the present embodiment, in the time writing incoming frame instruction wr_cmd and not writing motion image detection circuit 310 corresponding to view data, frame count circuit 312 can reduce the added up frame count value wr_cnt that writes according to writing incoming frame instruction wr_cmd, what therefore, now added up writes frame count value wr_cnt and can equal 1.Therefore, at the end time point Pf_i+1 of i+1 dynamic mass observation form 510_i+1, because the dynamic detected dynamic image number of decision-making circuit 314 does not reach default critical value M=2, therefore enable signal MQ_ON that can output low level is to arbitration circuit 320, maybe can not think that output enable signal MQ_ON, to arbitration circuit 320, shows to allow image displaying circuit 300 leave dynamic play.In addition, during i+2 dynamic mass observation form 510_i+2, the operation behavior of motion image detection circuit 310 can be analogized by above-mentioned, does not repeat them here.
Therefore, in the present embodiment, at the initial time point of each dynamic mass observation form, writing that frame count value wr_cnt can not be reset is 0, and it is add up not to restart calculating at the initial time point of each dynamic mass observation form by frame count circuit 212 constantly.In addition, in the present embodiment, corresponding to the window dimension signal win_s of dynamic mass observation form, its window dimension can't be along with the increase of sequential in each dynamic mass observation form but is remained on pre-set count values M, in this example, M=2, as shown in Figure 5.
Fig. 6 illustrates the summary circuit diagram of the motion image detection circuit of one embodiment of the invention.Please refer to Fig. 6, the frame count circuit 612 of the present embodiment comprises selector unit 611, adder unit 613 and counter unit 615.Selector unit 611 selects to export the first count value+1 or the second count value-1 to adder unit 613 according to writing incoming frame instruction wr_cmd.In this example, when writing incoming frame instruction wr_cmd and being high level, selector unit 611 selects output the first count value+1 to adder unit 613.Otherwise when writing incoming frame instruction wr_cmd and being low level, selector unit 611 selects output the second count value-1 to adder unit 613.Adder unit 613 is coupled to selector unit 611, write frame count value and the first count value+1 or the second count value-1, and output adds overall result to counter unit 615 in order to add up.Counter unit 615 couples adder unit 613, in order to carry out stored counts and write frame count value wr_cnt according to adding overall result, and exports and writes frame count value wr_cnt to dynamic decision-making circuit 614 according to frame clock signal CLK.Counter unit 615 is herein for example a D flip-flop (D flip-flop), and it writes frame count value wr_cnt to dynamic decision-making circuit 614 according to frame clock signal CLK in each output image duration.
Then, dynamically decision-making circuit 614 comprises comparator unit 617 and counter unit 619.Comparator unit 617 can be implemented by comparison amplifier, and in order to relatively to write frame count value wr_cnt and pre-set count values M, and output comparative result is to counter unit 619.Counter unit 619 couples comparator unit 617, in order to receive comparative result, and carrys out output enable signal MQ_ON to arbitration circuit according to frame clock signal CLK.As previously mentioned, the setting of the deviant between each dynamic mass observation form can be 1,2,3 ..., or N-1 frame, its embodiment is for example that the frame clock signal CLK to inputing to counter unit 619 sets.If it is set as 1, dynamically decision-making circuit 614 can upgrade to differentiate whether leave dynamic play demonstration at 1 frame.If it is set as 2, dynamically decision-making circuit 614 can just differentiate whether leave dynamic play demonstration after 2 frames upgrade, by that analogy.
Fig. 7 illustrates the flow chart of steps of the motion image detection method of one embodiment of the invention.Referring to Fig. 4 and Fig. 7, the motion image detection method of the present embodiment is for example applicable to the motion image detection circuit 310 of Fig. 4, and it comprises the steps.In step S700, define multiple dynamic mass observation forms.Then,, in step S710, in each dynamic mass observation form, adjust and write frame count value wr_cnt according to writing incoming frame instruction wr_cmd.Afterwards, in step S720, at the end time point of each dynamic mass observation form, equal pre-set count values M if write frame count value wr_cmd, output enable signal MQ_ON is to arbitration circuit 320, to determine whether image displaying circuit 300 carries out dynamic play demonstration.
In addition, the motion image detection method of embodiments of the invention can, by obtaining enough teachings, suggestion and implementation in the narration of Fig. 3 to Fig. 6 embodiment, therefore repeat no more.
In sum, in exemplary embodiment of the present invention, after image displaying circuit enters and dynamically displays the play, whether can setting according to side circuit design requirement of the deviant between each dynamic mass observation form, need to leave dynamic demonstration to differentiate image displaying circuit.Therefore, in the time that dynamic display frame has stopped upgrading, image displaying circuit of the present disclosure can be left dynamically and display the play in the less time, to reduce the stand-by period and to save unnecessary power consumption.
Although the present invention with embodiment openly as above; so it is not in order to limit the present invention; those skilled in the art without departing from the spirit and scope of the present invention, when doing a little change and retouching, are as the criterion depending on appended claims confining spectrum therefore protection scope of the present invention is worked as.
