Embodiment
Please refer to Fig. 1, the device of image scanning 1 of the automatic startup scanning of one embodiment of the invention comprises platform 11, light source 12, image sensor 13, driver element 14 and a controller 15.Platform 11 such as, in order to carry object 20, file, books etc.Light source 12 is arranged at the side of platform 11, in order to provide an illumination light.For example, light source 12 can be a light-emitting diode or cold-cathode fluorescence lamp (cold cathodefluorescent lamp, CCFL).The reverberation of illumination light of image sensor 13 in order to capture object 20 reflection source 12 and send, to export a sensing image.For example, image sensor 13 can be a Charged Coupled Device (Cbarge Coupled Device, CCD), CMOS (Complementary Metal Oxide Semiconductor) (ComplementaryMetal Oxide Semiconductor, CMOS) transducer or contact image sensor (Contact ImageSensor, CIS).
In an embodiment, platform 11 can be a transparent material, and light source 12 and image sensor 13 can be arranged at the below of platform 11.The illumination light that light source 12 sends can pass through platform and impinges upon object 20 surface.Illumination light can be captured by image sensor 13 and form image after object 20 surface reflection.The person of should be noted, light source 12 and image sensor 13 also can be arranged at the top of platform and not depart from spirit of the present invention.
Driver element 14 is connected with image sensor 13, in order to drive image sensor 13 to move relative to object 20, to scan large-area image.For example, driver element 14 orders about image sensor 13 and moves along track 141, with the complete scan image making image sensor 13 can capture object 20.The person of should be noted, driver element 14 is connected with platform 11, and orders about platform 11 and move the object that also can reach scanning large area image relative to image sensor 13.
Controller 15 is electrically connected with image sensor 13 and driver element 14, in order to control image sensor 13 and driver element 14 starts scanning operation.In addition, controller 15 also can analyze sensing image that image sensor 13 captures to judge whether platform 11 exists the object 20 needing scanning.Scanning operation can be started, such as preview image, scan-image, foundation object type change sweep parameter etc. when platform 11 exists object 20.
Please refer to Fig. 3, so that the operating process of device of image scanning 1 of the present invention to be described.First, when starting shooting when device of image scanning 1 or switch to automatic scan pattern from manual scanning pattern, namely image sensor 13 moves to predetermined detection position (S31), and pick-up image (S32).Namely controller 15 analyzes the sensing image (S33) that image sensor 13 captures, and judges whether platform 11 exists object 20 (S34).If platform 11 does not exist object 20, namely image sensor 13 continues pick-up image in predetermined detection position.If platform 11 exists object 20, controller 15 namely starts image sensor 13 and driver element 14 carries out scanning operation (S35).After completing image scan (S36), image sensor 13 moves to predetermined detection position (S31) again, and pick-up image judges for controller 15 analysis.
In an embodiment, according to the degree change of the sensing image of one or many acquisition, controller 15 can judge whether platform 11 exists object 20.For example, image sensor 13 is when predetermined detection position pick-up image, and light source 12 provides permanent bright illumination light.When platform 11 exists object 20, object 20, by indirect illumination light, causes sensing image to produce brightness change.When brightness change is more than a set point, or when brightness changes more than a setting-up time, can judge that platform 11 exists object 20, namely controller 15 starts scanning operation.In an embodiment, image sensor 13 is when predetermined detection position pick-up image, and light source 12 can be intermittent luminous.When platform 11 not existing object 20, the brightness change of sensing image is little.And when sensing image produces the brightness change of rule, can judge platform 11 exists object 20, controller 15 starts scanning operation.
Please refer to Fig. 2 a, in an embodiment, image sensor 13 can be divided into multiple sensing block 13a-13e by controller 15, and analyzes the brightness change of the sensing image that each sensing block 13a-13e captures respectively.For example, object 20 is placed in the detection range of sensing block 13a, 13b, 13c, and the brightness of the sensing image causing the brightness sensing the sensing image that block 13a, 13b, 13c capture to capture with sensing block 13d, 13e produces difference.There is object 20 in the detection range that controller 15 can judge to sense block 13a, 13b, 13c by this, controller 15 can start scanning operation.In an embodiment, when object can be detected more than the sensing block of a predetermined quantity in sensing block 13a-13e, just judge that object 20 exists.Can avoid some situations judged by accident by this, the foreign material that such as volume is less than set point drop on the brightness change caused in detection range.
Please refer to Fig. 2 b, in an embodiment, image sensor 13 is divided into multiple sensing block 13a-13e, the brightness change of the sensing image that controller 15 not only can be allowed to capture by sensing block 13a-13e judges whether platform 11 exists object 20, and the brightness change of the sensing image that controller 15 also can capture according to respective sense block 13a-13e performs corresponding operation.For example, the finger 30 of user is placed in the detection range of sensing block 13e, the brightness of the sensing image of sensing block 13e is caused to change, namely controller 15 performs corresponding operation, and such as setting scans classification (black and white/GTG/colour), adjusts resolution, switches manual/auto scan pattern etc.In other words, the sensing block 13a-13e of suitably configuration can be used as the operation-interface of a user.The person of should be noted, the size, position etc. of sensing block 13a-13e can make alterations according to actual demand.In addition, image sensor 13 can be point-like, linear, face shape or irregularly shaped configuration.
Comprehensively above-mentioned, the device of image scanning of automatic startup scanning of the present invention utilizes the image on the image sensor acquisition platform of device of image scanning itself, more directly judge whether platform has object exist, to start scanning operation according to this by image analysing computer.Therefore, the device of image scanning of automatic startup scanning of the present invention additionally need not arrange nextport hardware component NextPort and automatically starting scanning operation, not only can reduce costs and can simplify the operation of user, and then improving sweep efficiency.
Above-described embodiment is only for technological thought of the present invention and feature are described, its object is understood content of the present invention and implements according to this enabling to be familiar with the art person, when can not with restriction the scope of the claims of the present invention, namely all equalizations done according to disclosed spirit change or modify, and must be encompassed in the scope of the claims of the present invention.
