Please refer to Figure 1A to Figure 1B, user can by rapidly toward the direction near Image Sensor 110 by thumb Finger and forefinger separate are (such as：The action pushed aside) to carry out during a control command (such as：Amplification instruction), now thing Part image size will rapidly become big in fixed time interval Δ T, and such as the continuous action of Figure 1A to Figure 1B and Fig. 2's is oblique Shown in rate L1.Specifically, user is intended to carry out a direction movement (such as by gesture：Rapidly near Image Sensor 110) during control command (for example：Amplification instruction), its gesture would generally be very fast in the rate travel that this side up, furthermore, by Action gesture depicted in Figure 1A to Figure 1B is by thumb and forefinger separate, and therefore Image Sensor 110 is sensed The change of object image size will little by little become big, based on above-mentioned, the object image that Image Sensor 110 is sensed is big Will rapidly become big less than in the continuous time.

Relatively, if during action command depicted in user Figure 1A to Figure 1B to be repeated, inevitably, user Gesture just needs first to recover the aspect of former handss formula, the recovery gesture motion as depicted in Fig. 1 C to Fig. 1 F, then just repeats it The action command to be carried out is (such as：Action command depicted in Figure 1A to Figure 1B).Specifically, recover the gesture of former action in advance The time needed for action gesture that time needed for action would generally relatively be carried out is long, and therefore user is by aforesaid action command Gesture recover to former handss formula aspect (such as：Continuous action depicted in Fig. 1 C to Fig. 1 F) when, Image Sensor 110 is felt The object image size surveyed will relatively slower speeds diminish in 3 fixed time interval Δ T, such as the company of Fig. 1 C to Fig. 1 F Shown in the slope L2 of continuous action and Fig. 2.In the present embodiment, quick and at a slow speed definition is the relative velocity within continuous time Performance, as depicted in the continuous action of Figure 1A to Fig. 1 F and slope L1, L2 of Fig. 2.

Specifically, when user is intended to the gesture replying former action in advance, the action that it is replied is in the shifting that this side up Dynamic speed would generally be relatively slow, the continuous action as depicted in Fig. 1 C to Fig. 1 F, furthermore, due to the action depicted in Fig. 1 C to Fig. 1 F Gesture is by adjacent to each other to thumb and forefinger/contact, the change of the object image size that therefore Image Sensor 110 is sensed Will little by little diminish, based on above-mentioned, the object image that Image Sensor 110 is sensed is less than greatly will in the continuous time Slower speeds diminish.Based on above-mentioned, when the object image that processing unit 120 judges in image information I1 was less than greatly in the continuous time Quick change becomes hour greatly and at a slow speed, now will export the first instruction C1, the wherein first instruction C1 is, for example, an amplification instruction.And When the action depicted in user continuously repeats Figure 1A to Fig. 1 F, processing unit 120 will continuously export the first instruction C1, also Amplification instruction can continuously be exported.

It should be noted that the gesture detector 100 of the present embodiment is mainly gesture and recovery according to action command The speed of the gesture of action command is different, and the gesture easily being instructed the gesture of action command with recovery action with solving tradition is regarded Export two kinds of instructions for two kinds of different instructions respectively, thus easily producing the situation of erroneous judgement.For example：Continuously repeat Figure 1A extremely Action depicted in Fig. 1 F, will produce continuous different instruction and produce, but user is only intended to continuously generate same instruction. In other words, the gesture detector 100 of the present embodiment can be by judging the gesture of action command and the gesture of recovery action instruction Speed different, and judge that user is primarily intended to carry out the input of single instruction, furthermore, the gesture of the present embodiment Detector 100, when continuously repeating the action depicted in Figure 1A to Fig. 1 F, just can continuously export the first instruction C1, also can connect Continuous output amplification instruction, without producing misoperation.

Fig. 3 A to Fig. 3 F is that the gesture detector of one embodiment of the invention judges that the flow process of another continuous gesture is illustrated Figure, and Fig. 4 is then to continuously repeat gesture motion depicted in Fig. 3 A to Fig. 3 F produced object shadow on Image Sensor As the graph of a relation of size and time, wherein Fig. 3 A to Fig. 3 F mainly illustrates user and is intended to quickly to lean on mutually thumb and forefinger Closely/contact is (such as：Crawl action) gesture carry out instruction output, and the action of this crawl can for be rapidly directed away from image sensing unit The continuous action of part 110.In the present embodiment, Fig. 3 A to Fig. 3 F is the continuous action under fixed time interval Δ T.

Please refer to Fig. 3 A to Fig. 3 D, user can be first slower speeds toward the direction near Image Sensor 110 and by thumb Finger and forefinger separate are (such as：The action pushed aside), using as be subsequently intended to quick by adjacent to each other to thumb and forefinger/ Contact is (such as：Crawl action) preliminary activities, now object image size assume phase in 3 fixed time interval Δ T To slower speeds becoming big, as shown in the continuous action of Fig. 3 A to Fig. 3 D and the slope L3 of Fig. 2.Similarly, the handss of preliminary activities are carried out The time needed for gesture motion that time needed for gesture would generally more subsequently be carried out is long, therefore, when user is intended to be prepared During the gesture of action, the gesture of its warming up would generally be relatively slow in the rate travel that this side up, as Fig. 3 A to Fig. 3 D paints The continuous action shown, furthermore, because the action gesture depicted in Fig. 3 A to Fig. 3 D is by thumb and forefinger separate, because The change of the object image size that this Image Sensor 110 is sensed will little by little become big.

Then, refer to Fig. 3 E to Fig. 3 F, user just can be by rapidly toward the direction away from Image Sensor 110 By adjacent to each other to thumb and forefinger/contact (such as：Crawl action) gesture to carry out during a control command (such as：Reduce finger Make), now object image size will rapidly diminish in fixed time interval Δ T, as continuously moving of Fig. 3 E to Fig. 3 F Shown in the slope L4 of work and Fig. 4.Similarly, if user is intended to carry out a direction movement (such as by gesture：Rapidly away from image Sensing element 110) control command when (for example：Reduce instruction), its gesture would generally be very fast in the rate travel that this side up. Furthermore, because the action gesture depicted in Fig. 3 E to Fig. 3 F is quickly by adjacent to each other to thumb and forefinger/contact (such as：Crawl Action), the change of the object image size that therefore Image Sensor 110 is sensed will rapidly diminish, based on above-mentioned, shadow As the object image that sensing element 110 is sensed is less than in the continuous time greatly and will rapidly diminish.In the present embodiment, soon Speed is relative velocity within continuous time with definition at a slow speed, the such as slope L3 of the continuous action of Fig. 3 A to Fig. 3 F and Fig. 4, Depicted in L4.
