Description
- The invention is directed to methods and apparatus for scanning objects and, more particularly to a system for providing swipe or presentation image scanning.
- There are numerous standards for encoding numeric and other information in visual form, such as the Universal Product Codes (UPC) and/or European Article Numbers (EAN) used to identify products sold throughout the world. These numeric codes allow businesses to identify products and manufactures, maintain vast inventories, and manage a wide variety of objects under a similar system and many other functions. The UPC or EAN of the product is printed, labeled, etched, or otherwise attached to the product as a dataform.
- Dataforms are any indicia that encode numeric and other information in visual form. For example, dataforms can be barcodes, two dimensional codes, marks on the object, labels, signatures, signs etc. Barcodes are comprised of a series of light and dark rectangular areas of different widths. The light and dark areas can be arranged to represent the numbers of a UPC. Additionally, dataforms are not limited to products. They can be used to identify important objects, places, etc. Dataforms can also be other objects such as a trademarked image, a person's face, etc.
- Dataforms are decoded by scanners. The scanners can be coupled to another device, such as, for example, a cash register or a mobile computer, for further processing of the captured dataform. There are many different types of scanners, for example, laser based scanners, imaging based scanners, presentation or swipe scanners, handheld scanners, etc. Some scanners can have dual modes. For example, a handheld scanner can be configured to operate in either a stationary presentation mode, where the dataform is presented to the scanner or in a mobile handheld mode, where the scanner is pointed at the dataform. In some configurations the scanner can be securely placed in a stand while in presentation mode.
- Presentation or swipe scanners have become very common, but they are mostly based on laser scanning technology. Image scanners have normally not been used in a presentation or swipe mode because the target dataform is usually moving when the dataform is in the field of view of the scanner. The movement of the dataform causes motion blur and the captured dataform image may not be clear. The blurry image results in a failed attempt or a long decode time. Either option is not desirable since, they slow down a checkout or inventory process.
- Accordingly, a need exists for methods and apparatus that can assist image scanners with decoding dataforms in a swipe or presentation mode.
- The invention as described and claimed herein satisfies this and other needs, which will be apparent from the teachings herein. An embodiment of the invention includes methods and apparatus for swipe or presentation image scanning.
- An exemplary embodiment of the invention comprises, a scan stand for a scanner comprising an illumination system, comprising a scan stand illumination module and/or a scanner illumination module, and a receiving structure for receiving and supporting the scanner. The combination of the scan stand illumination module and the scanner illumination module in a second mode provides an illumination greater than the scanner illumination module in a first mode. In alternate embodiments, the scan stand further comprises a detection component for activating the illumination medium of the scan stand. The illumination module can be, in some embodiments, a light emitting diode (LED), and the scanner may comprise more than one LED. Additionally, the stand can be configured to mount the scanner horizontally or vertically.
- In an embodiment of the invention, the detection component of the scan stand is implemented as a photodiode. The photodiode detects when an attached scanner is emitting light and correspondingly activates the scan stand illumination module. In other embodiments, the scan stand illumination can be activated by a button or switch, or the scanner and the stand can be electrically coupled and send signals to each other. The button or switch can be positioned inside the receiving structure so that it is pressed or switched when a scanner is placed in the stand. Alternatively or in addition, a button or switch can be positioned anywhere else on the stand and manually turned on and off by an operator, or in an alternate embodiment, the illumination can be left constantly on and never switched by any means.
- The additional illumination provided by the scan stand allows the scanner to decrease its exposure time and thus decrease the blurriness of moving targets in captured images. Therefore, an exemplary scanner implemented in accordance with the invention comprises a scan module, a processing unit, a detection component for detecting the coupling of the scanner to a scan stand and memory. The memory comprising a method stored thereon for decreasing the exposure time of the scanner when the detection module is activated.
- Other objects and features of the invention will become apparent from the following detailed description, considering in conjunction with the accompanying drawing figures. It is understood however, that the drawings are designed solely for the purpose of illustration and not as a definition of the limits of the invention.
- The drawing figures are not to scale, are merely illustrative, and like reference numerals depict like elements throughout the several views.

For example, the stand may be configured to activate its illumination module when an attached scanner's illumination module is activated. This can be achieved by positioning the illumination module of the scanner in the vicinity of a photodiode. When the photodiode detects the activation of the scanner's illumination module, the stand activates its illumination module.
- Alternatively, the scan stand may comprise a button or switch that activates the stand's illumination module. The switch can be located in a receiving structure for the scanner so that the switch is turned on, when a scanner is coupled to the stand. In another embodiment, the button or switch can be located anywhere else on the stand, and switched on or off by a scan stand operator.
- In some embodiments, the scanner can be electrically or wirelessly coupled to a scan stand so that they can communicate signals to each other. In this example, the scanner can transmit a signal to a detection component of a scan stand, or the scan stand can be configured to automatically sense a coupled scanner. Further signals and/or messages can be communicated between the scanner and the stand, such as, for example, when the stand should activate its illumination module.

FIGS. 6 and 7 illustrate exemplaryimage scanning methods Method 600 is used with a scan stand detection component implemented as aphotodiode 130, andmethod 700 is used with a scan stand detection component implemented as aswitch 305. The steps ofmethod -
Image scanning method 600 begins withstart step 605. In an exemplary embodiment, themethod 600 begins when thescanner 120 is placed in the receivingunit 122 of thescan stand 120. Processing proceeds fromstep 605 to step 610, where thescanner 120 switches to a presentation mode. For example, followingstep 610, instep 615 the exposure time for thescanner 120 is decreased. The bright illumination provided by the scan standillumination module 135 allows thescanner 120 to reduce its exposure time. Decreasing the exposure time produces clearer pictures of moving objects and thus increasing scanning performance in a presentation mode. In some embodiments, thescanner 120 can take further steps such as decreasing the intensity of its own illumination module. In an embodiment of the invention, the scanner's 120 exposure time is decreased by switching from a first decoding algorithm with a predetermined maximum exposure time to a second decoding algorithm with a shorter predetermined maximum exposure time. - Following
step 615, processing proceeds to step 620, where thescan stand 102 detects illumination from thescanner 120, for example, through aphotodiode 130 or through a signal transmitted over a communication channel. Once illumination is detected, processing proceeds fromstep 620 to step 625, where thescan stand 102 activates itsillumination module 135. Followingstep 625, instep 630 thescanning system 100 is ready to capture and analyze dataforms. -
Method 700, illustrated inFIG. 7 , is similar tomethod 600, but in this exemplary method thedetection component 305 is implemented as a switch or a button.Steps 705 through 715 and 725 through 730 ofmethod 700 are similar tosteps 605 through 615 andsteps 625 through 630 ofmethod 600. The difference betweenmethods step 720, where the scan stand detects a coupled scanner using a button or switch instead of based on the illumination module of the scanner. The button or switch can be located within the receivingstructure 322 of a scan stand so that the stand automatically activates its illumination module when a scanner is couple to it. - While there have been shown and described and pointed out fundamental novel features of the invention as applied to preferred embodiments thereof, it will be understood that various omissions and substitutions and changes in the form and detail of the disclosed invention may be made by those skilled in the art without departing from the spirit of the invention. It is the intention, therefore, to be limited only as indicated by the scope of the claims appended hereto.
