Fig. 1 shows the application synoptic diagram according to the Image sensor apparatus 1 of first embodiment of the invention.Described Image sensor apparatus 1 is a fingerprint acquisition apparatus or other biological identification sensing apparatus.In present embodiment, described Image sensor apparatus 1 is fingerprint acquisition apparatus particularly, and its sensing one object 2 for example is finger.When finger was mobile above described sensing apparatus, described sensing apparatus also can obtain the information of sensing finger moving direction, whereby to be made for other application except reading finger print data.
With the practical application is example, sees also Fig. 5, can utilize the clockwise arc motion of finger on sensing apparatus that the photo that screen shows is amplified, or as utilize finger as Fig. 6 left-handed with as described in photo dwindle.Such function increase be present Trackpad or any rocking bar do not provide, also be core of the present invention place.
As shown in Figure 2, described Image sensor apparatus 1 has comprised an image sensor 10 and a processing unit 20.For convenience of explanation, described image sensor is only represented (functionalblock) with a function square in the present invention, in fact described image sensor more can be subdivided into the subfunction square (sub-functional blocks) that has following function at least, a sensing element array for example, the signal amplifier that one Gain Adjustable is whole, one analog/digital signal conversion device, steering logic and output/input interface (interface), above-mentioned subfunction square can be integrated design (monolithic, SOC) or hybrid welding (hybrid-bonding) or systematization packaged type (System In a Package, SIP) design, and the principle of sensing unit can be any sensing principle, capacitance sensing for example, electric field and magnetic field, radio frequency (RF), optics, ultrasonic, pressure or infrared ray or the like.Sensing unit is disposed on the substrate, and substrate can be made up of the semiconductor material such as silicon, or by being formed such as glass, polymkeric substance (PI) etc. or other insulating material.Sensing unit can be the sensing unit of a kind of condenser type, pressure type, temperature difference induction type, optical profile type, Electric field, electromagnetic field type, RF formula, infrared-type, piezoelectric type, ultrasonic formula or other patterns.
Identical, described processing unit and described sensor also can be made in same wafer (monolithic, SOC), also or hybrid welding (hybrid-bonding) or systematization encapsulation (SIP).And described processing unit has comprised a calculation unit and a memory cell basically, the temporary signal of video signal of exporting by sensor of memory cell, and the calculation unit provides a kind of image treatment method, to handle the described signal of video signal that is temporary in the storer, with moving direction and the track that obtains image, also or the association between wantonly two images.Perhaps, whole signal amplifier, analog/digital signal conversion device, steering logic and the output/input interface of aforesaid Gain Adjustable also can be moved to processing unit.
In application of the present invention, described Image sensor apparatus 1 can have various modes output.First pattern is a plurality of first images of the object 2 during sensing moves, and at described a plurality of first images of described sensing apparatus 1 inter-process with the motion message signal of exporting corresponding described object 2 in external system, as shown in Figure 1, the message signal of the corresponding finger of output circular motion curve.
A plurality of first signal of video signal SI1 are corresponding to these first images.Processing unit 20 receives these first signal of video signal SI1, with a corresponding curvilinear motion path of the object 2 in obtaining to move according to these first signal of video signal SI1, to export a curvilinear motion identifying information SR.A kind of embodiment of the purposes of curvilinear motion identifying information SR as described previously can be by reaching counterclockwise message shows object as application program amplification and reduction capability clockwise.
Under one second pattern, image sensor 10 is a plurality of second images of object sensing 2 more, to export a plurality of second signal of video signal SI2 of corresponding described second image, and processing unit 20 is more handled the association between the second signal of video signal SI2 of described wantonly two second images, the part output that for example two images is not overlapped mutually is to export a final signal of video signal SF.In another example, image sensor 10 is single second image of object sensing 2 more, and exporting one second signal of video signal SI2 of corresponding second image, and processing unit 20 is more handled the second signal of video signal SI2, to export final signal of video signal SF.
Under a three-mode, a plurality of the 3rd images of the object 2 during image sensor 10 sensings move, to export a plurality of the 3rd signal of video signal SI3 of corresponding these grade in an imperial examination three images, and processing unit 20 more receives this grade in an imperial examination three signal of video signal SI3, with a corresponding straight line motion path of the object 2 in obtaining to move according to this grade in an imperial examination three signal of video signal SI3, to export a motion vector signal SD.
It should be noted that, above-mentioned three kinds of patterns can have independently output, also or the output that mixes, first pattern and three-mode can be judged by processing unit, just the go ahead of the rest motion path of judgment object of processing unit is straight line or curve, with simple message output, this measure can reduce the processor resource of outside receiving system, needn't repetitive operation again.
