Fig. 2 is the process flow diagram of control method of the sensing system that is applied to Fig. 1 of first embodiment of the invention.Fig. 3 is the detail flowchart of the control method of Fig. 2.Fig. 4 is the first image sensor and the first image that the second image sensor senses and the schematic diagram of the second image of the sensing system of Fig. 1.Please refer to Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, comprehensive speech, the control method that is applied to sensing system of the present embodiment comprises that the size according to the one first total image P1 that captures determines whether starting specific function.In the present embodiment, above-mentioned steps is: determine whether starting specific function according to size and the lasting length that captures the time of first total image P1 of the one first total image P1 that captures.Below will further describe.
At first, carry out substep a), the first image sensor 220 and the second 230 while of image sensor sensing region 212 are to obtain respectively one first image 222 and one second image 232.The first image 222 comprises one first subimage 222a, and the second image 232 comprises one second subimage 232a, and the first subimage 222a and the second subimage 232a formation first total image P1.
In the present embodiment, the first image sensor 220 has first sensor pixel (not illustrating) in this zone 212 of a plurality of sensings, and the second image sensor 230 has second sensor pixel (not illustrating) in this zone 212 of a plurality of sensings.When one first object (not illustrating) is close to the zone 212 of panel 210, these second sensor pixels of these first sensor pixels of the first image sensor 220 and the second image sensor 230 are sensing region 212 simultaneously, these the first sensor pixel acquisition first images 222 of the first image sensor 220, and these the second sensor pixel acquisition second images 232 of the second image sensor 230.At this moment, at least part of these the first sensor pixel sensing first objects and capture the first subimage 222a, and at least part of these the second sensor pixel sensing first objects and capture the second subimage 232a.In other words, in this at that time, the zone 212 of the first contiguous panel 210 of object and captured into the first subimage 222a in the first image 222 by 230 sensings of the first image sensor 220 and the second image sensor and the second subimage 232a in the second image 232.
The first object can be a stylus, a finger, a blackboard eraser or a palm.If the first object is stylus or finger, the size of first total image P1 is less.The size of first total image P1 for example is the quantity of the first sensor pixel of these correspondences of acquisition the first subimage 222a and the summation of the quantity of these second corresponding sensor pixels that capture the second subimage 232a.In addition, if the first object is blackboard eraser or palm, the size of first total image P1 is larger.Should be noted that at this, the first subimage 222a shown in Figure 4 and corresponding the first object of the second subimage 232a are for example blackboard eraser.
What be worth emphasizing is, when a plurality of the first objects are close to the zone 212 of panels 210, for example during the zone 212 of two finger contact panels 210, the first image 222 can comprise a plurality of the first subimage 222a, and the second image 232 can comprise a plurality of the second subimage 232a.At this moment, these the first subimage 222a and these second subimages 232a consist of first total image P1, and the size of first total image P1 is the quantity of the first sensor pixel of these correspondences of these first subimages of acquisition 222a and the summation of the quantity of these second corresponding sensor pixels of these second subimages of acquisition 232a.
Then, carry out substep b), processor 240 judges that whether the size of first total image P1 is more than or equal to one first predetermined value.In the present embodiment, the first predetermined value can be a specific number of pixels, its for example between the summation of the quantity of these the second sensor pixels of the quantity of these the first sensor pixels of the first image sensor 220 and the second image sensor 230 1/2nd to 2/3rds between.
Then, carry out substep c), if the size of first total image P1 more than or equal to the first predetermined value, so judgement whether continue to capture the time of first total image P1 more than or equal to one second predetermined value (for example 1.5 seconds).Should be noted that substep c shown in Figure 2 at this) can complete by the mode of counting shown in Figure 3.For example, the first image sensor 220 and the second image sensor 230 be designed at set intervals interval (being for example 1/240 second) can sensing region 212 once.When the first image sensor 220 and second image sensor 230 each sensing region 212, processor 240 judges that all whether the size of first total image P1 is more than or equal to the first predetermined value at every turn.If every judgement is once yes, count value (counting value) increase by 1 and processor 240 so judge that whether count value is more than or equal to one the 3rd predetermined value (as the subprocess c2 of Fig. 3) and c3)).In the present embodiment, the second predetermined value is for example 1.5 seconds) calculate (for example 1.5 divided by 1/240) through the deviser and be converted to the 3rd predetermined value (for example 360 times).
Then, carry out substep d), if continue the time of acquisition first total image P1 more than or equal to the second predetermined value (that is count value is more than or equal to the 3rd predetermined value), processor 240 startup specific functions and calculating and export the first subimage 222a and the second subimage 232a one first coordinate of corresponding the first object instantly.In the present embodiment, in this at that time, the first object for example is considered as a cleanout tool for blackboard eraser or palm sensed system 200, and specific function for example is the panel 210 of touch-screen or the other shown motion track of display for removing, that is specific function can be one and removes function.
In addition, carrying out substep b) afterwards, the control method that is applied to sensing system more comprises carries out substep c1), if the size of first total image P1 is less than the first predetermined value, processor 240 calculate and export the first subimage 222a and the second subimage 232a instantly corresponding the first object the first coordinate and get back to substep a).In the present embodiment, in this at that time, the first object for example was considered as an indicant for stylus or finger sensed system 200.
In addition, carrying out substep c) afterwards, the control method that is applied to sensing system more comprises carries out substep d1), if continue the time of acquisition first total image P1 less than the second predetermined value (that is count value is less than the 3rd predetermined value), processor 240 calculating and export the first subimage 222a and the second subimage 232a instantly corresponding the first object the first coordinate and get back to substep a).In the present embodiment, in this at that time, the first object for example for blackboard eraser or palm but because of the time that is continued acquisition the sensed system 200 that falls short of be considered as indicant.For example, in this at that time, the user may be by mistake moves blackboard eraser or palm with blackboard eraser or palm adjacent domain 212 and at once and left zone 212, and sensing system 200 can be avoided erroneous judgement and start above-mentioned specific function.
Should be noted that at this, above-mentioned substep a), b), b1), c), d) and d1) consisted of for the first control stage.In the first control stage, but each thing of the first image sensor 220 and 230 sensings of the second image sensor all is called the first object.In other words, in the first control stage, but the first object is the common appellation of each thing of the first image sensor 220 and 230 sensings of the second image sensor.
Due in the control method that is applied to sensing system of the present embodiment, determine whether starting specific function according to the size of the first total image P1 that captures, so using, the user has the sensing system 200 of above-mentioned control method with more convenient.In addition, in the control method that is applied to sensing system of the present embodiment, above-mentioned steps can be: determine whether starting specific function according to size and the lasting length that captures the time of first total image P1 of the first total image P1 that captures, so sensing system can be improved because of the situation that erroneous judgement starts specific function.
