[0015] The present disclosure broadly discloses a document scanning device having an optical array for defining a scan area on a glass platen of the document scanning device. As described above, one example of a document scanning device is an MFD, which may include a glass platen on which a document is placed. A scanner may be located below the glass platen to scan an image for copying, scanning, or faxing. For example, a document may be placed on the glass platen, a scan function may be initiated, and the scanner may move across the glass platen to capture an image of the document.

[0016] For scanning or copying functions, the MFD may expect documents to be placed in a particular location and orientation. Some MFDs may have static indicators to identify the origin; however, many do not indicate the orientation. For example, documents of different sizes may be placed in different orientations. To illustrate, some documents of different sizes may be placed in portrait orientation, while other documents of different sizes may be expected to be placed in landscape orientation.

[0017] Without proper orientation instructions, a user may place a document on the platen glass in the incorrect orientation, and after the document is scanned, the user may realize that the document was placed in the incorrect orientation and may have portions of the document missing from the scan job.

[0018] Additionally, when scanning documents of several different sizes, a user may have to go through a series of menus on the user interface to change the paper size and scan area. Going back and forth between scanning and selecting in the user interface can be time-consuming and inefficient.

[0019] The present disclosure provides a light array located around the perimeter of the platen glass of an MFD. The light array may be dynamically controllable to provide indication of the correct origin and orientation of a document on the platen glass for a scan or copy function. For example, a user may select a scan function and an appropriate paper size. Based on the selection, the MFD can illuminate portions of the light array around the platen glass that indicate the document's origin and orientation.

[0020] In one embodiment, the light array may include a touch sensor that can be used to activate and / or deactivate selected portions of the light array. A user can swipe in a first direction to activate portions of the light array and swipe in a second, opposite direction to deactivate portions of the light array. The touch sensor light array may allow a user to select the origin and orientation of a scan job via selection of a desired area with the touch sensor light array. The selection may then be processed by the MFD and changed accordingly to the appropriate menu selection in the user interface.

[0021] Additionally, the touch sensitive light array may allow a user to easily crop portions of a document using the touch sensitive light array, define different active scan areas on the platen glass for different documents to be scanned simultaneously, etc. As a result, a platen glass with a light array of the present disclosure can allow scanning and / or copying of documents on an MFD to be performed more accurately and efficiently.

[0022] FIG. 1 illustrates an exemplary MFD 100 of the present disclosure. Note that FIG. 1 illustrates a simplified block diagram of MFD 100 and may include additional components not shown. For example, MFD 100 may include paper trays, a digital front end, various paper transport paths, finishing options, an output tray, etc. MFD 100 may also, more generally, be any type of document scanning device.

[0023] In one embodiment, the MFD 100 may include a glass platen 102 that can receive a document 104. An optical scanner 106 may be used to scan the document 104 on the glass platen 102. The optical scanner 106 may be a charge coupled device (CCD).

[0024] In one embodiment, MFD 100 may include a user interface 116. User interface 116 may be a graphical user interface (GUI) with a touch screen or a user interface with physical buttons. User interface 116 may allow a user to select parameters for a scan or copy job. For example, parameters may include paper size, resolution, image size, number of copies, finishing options, etc.

[0025] In one embodiment, memory 120 may include instructions executed by processor 118 to automatically detect the original size of document 104 placed on platen glass 102. Processor 118 may then automatically select certain parameters of a scan job based on the detected size of document 104. For example, the MFD may have an "auto-detect" feature to detect certain parameters of a scan job. Note that while the examples described herein may refer to scan jobs, embodiments of the present disclosure may also apply to copy jobs.

[0026] In one embodiment, MFD 100 may include light array 108 and light array 110. Light arrays 108 and 110 may be located around the perimeter of glass platen 102. At least one light array 108 may be located adjacent to glass platen 102 along the length of the perimeter, and at least one light array 110 may be located adjacent to glass platen 102 along the width of the perimeter. In other words, while FIG. 1 shows an example having four light arrays around glass platen 102, it should be noted that two light arrays (e.g., one light array 108 and one light array 110) may be deployed.

[0027] In one embodiment, the light array 108 includes a plurality of light sources 1121-1122. n (hereinafter also referred to individually as light sources 112 or collectively as light sources 112). In one embodiment, light array 110 includes multiple light sources 1141-114 m (hereinafter also referred to individually as light source 114 or collectively as light source 114). In one embodiment, light source 112 and light source 114 may be light emitting diodes (LEDs).

[0028] In one embodiment, the light sources 112 may be arranged in a single line along the length of the light array 108. The light sources 114 may be arranged in a single line along the length of the light array 110. In another embodiment, the light array 108 may include two different color light sources 112 arranged in alternating (e.g., green, red, green, red, etc.) single line or in two parallel lines. The light array 110 may also include two different color light sources.

[0029] Light sources 112 and 114 may be dynamically controlled based on parameters selected for the scan job to provide visual cues regarding origin and orientation. Origin may be where a corner of document 104 should be located. Orientation may indicate whether document 104 should be placed in portrait or landscape orientation. Light sources 112 and 114 may also be dynamically controlled to define a scan area. For example, a scan area may include a boundary within which optical scanner 106 may be active to capture image data from document 104. Defining different scan areas may allow a user to crop document 104, scan different portions of document 104, and simultaneously scan multiple different documents and documents of different sizes, as discussed in more detail below and illustrated in FIGS. 3-5.

[0030] In one embodiment, MFD 100 may include a processor 118 and memory 120. Processor 118 may be communicatively coupled to optical scanner 106, light arrays 108 and 110, user interface 116, and memory 120. Processor 118 may receive selected parameters from user interface 116 and dynamically control light sources 112 and 114 in light arrays 108 and 110, respectively.

[0031] For example, 8.5 x 11 inches (21.59cm x 27.94cm)A scan job with paper of 8.5 x 11 inches may have the origin at the top left corner of the platen glass 110. The default orientation may be landscape. As a result, if a user selects an 8.5 x 11 inch (21.59cm x 27.94cm) When a scan job having 8.5×11 inch paper is selected, the processor 118 changes the state of the light sources 112 and 114 to generate a landscape 8.5×11 inch paper with the origin at the top left corner of the platen glass 102. (21.59cm x 27.94cm) A scan area having a size of .times. ...

[0032] For example, light sources 112 and 114 may be controlled to be on and off, change color (e.g., red and green), etc. FIG. 1 illustrates a diagram in which light sources 1121-1126 in light array 108 are activated (e.g., turned on or changed to green), and light sources 1127-1128 are activated (e.g., turned on or changed to green). n The light sources 1141-1145 in the light array 110 are activated, and the light sources 1146-1147 are deactivated (e.g., turned off or changed to red). m has been deactivated.

[0033] As a result, when a user selects a scan job with 8.5×11 inch paper and opens the cover on platen glass 102, the user can see activated light sources 1121-1126 and 1141-1145. If the user attempts to place document 104 in portrait orientation, the user can quickly see that a portion of document 104 may extend beyond activated light sources 1145 in light array 110. Thus, activated light sources 1121-1126 and 1141-1145 quickly provide visual cues as to the correct scan area, origin, and / or orientation for the selected parameters of the scan job.

[0034] The user can (27.94cm x 35.56cm) For example, if a different scan job is selected with an 11×14 inch paper, the processor 118 may change the activated light sources 112 and 114. (27.94cm x 35.56cm)For this paper, light sources 1121-1129 may be activated and light sources 1141-1147 may be activated.

[0035] In one embodiment, memory 120 may store a table with the light sources 112 and 114 that should be activated for each parameter of a selected scan or copy job. Thus, processor 118 can determine which light sources 112 and 114 should be activated for the selected parameters from the table stored in memory 120.

[0036] In one embodiment, light arrays 108 and 110 may include touch sensors that may allow a user to dynamically change the scan area using the touch sensors rather than selecting various menus via user interface 116. Figure 2 shows a cross-sectional view of an example touch sensor 202.

[0037] 2 shows an exemplary touch sensor 202 coupled to the light array 108. However, it should be noted that the touch sensor 202 may also be coupled to the light array 110 and operate in a similar manner as described below.

[0038] In one embodiment, touch sensor 202 may be communicatively coupled to processor 118. In general, touch sensor 202 may be any type of touch sensor. For example, touch sensor 202 may be a capacitive touch sensor, a resistive touch sensor, etc. Touch sensor 202 may be optically transparent such that light emitted from light source 112 may be visible through touch sensor 202.

[0039] In one embodiment, touching the touch sensor 202 can change the state of the light sources 112 located under the area of ​​the touch sensor 202 that is touched. The memory 120 can store the x and y coordinates of the touch sensor 202 and which light sources 112 are associated with a particular x and y coordinate range on the touch sensor 202. When a particular location on the touch sensor 202 is touched, a signal including the x and y coordinates on the touch sensor 202 that was touched can be sent to the processor 118. The processor 118 can determine which light sources 112 are associated with the x and y coordinates and change the state of the light sources 112.

[0040] For example, if light source 1121 is active and touch sensor 202 above light source 1121 is touched, light source 1121 may be deactivated. If light source 1121 is inactive and touch sensor 202 above light source 1121 is touched, the light source may be activated.

[0041] In one embodiment, a subset of the light sources 112 may be controlled with a swipe gesture. In one embodiment, a first direction of the swipe gesture may activate the light sources 112 (e.g., from left to right) and a second direction of the swipe gesture may deactivate the light sources 112 (e.g., from right to left).

[0042] For example, a user can define different scan areas by using a swipe to select different subsets of light sources 112. For example, a user may touch touch sensor 202 above light source 1121 and swipe across touch sensor 202 to a position above light source 1124. The user may then lift their finger, touch touch sensor 202 above light source 1127, and swipe across touch sensor 202 to a position above light source 1129. As a result, light sources 1121-1124 may be activated to define a first scan area, and light sources 1127-1129 may be activated to define a second scan area. As a result, when the processor 118 controls the optical scanner 106, the optical scanner 106 can be controlled to capture an image of the document 104 between the areas corresponding to light sources 1121-1124, to be deactivated between the areas corresponding to light sources 1125-1126, and to be reactivated to capture an image of the document 104 between the areas corresponding to light sources 1127-1129.

[0043] Additionally, processor 118 may automatically change parameters within the appropriate menu selection within the scan job software. In other words, the user does not have to go through a menu selection within user interface 116. Rather, selection of a different scan orientation or scan area via touch sensor 220 causes processor 118 to automatically change parameters within the menu. For example, if a user uses touch sensor 202 to select an 11x14 inch screen in landscape orientation, the processor 118 may automatically change parameters within the menu. (27.94cm x 35.56cm) When the scan area is changed to correspond to 11×14 inch paper in landscape orientation, the processor 118 may change the scan job parameters displayed in the user interface to correspond to 11×14 inch paper in landscape orientation. (27.94cm x 35.56cm) The paper can be modified to be

[0044] In one embodiment, touch sensor 202 may provide additional scan job or copy job functionality. For example, a user may crop document 104, select different scan areas for document 104 (e.g., to organize specific portions of document 104), define multiple scan areas for multiple documents, etc. Figures 3-5 illustrate different examples of applications of touch sensor 202.

[0045] 3 illustrates an example of cropping a document 104 by selecting a specific scan area using the touch sensor 202 of the present disclosure. FIG. 3 illustrates an example in which two light arrays 108 and 110 are positioned around the perimeter of the platen glass 102.

[0046] First, a user may select a scan job for a document 104. The user may select a paper size of W×L. The processor 118 may activate a subset 302 of light sources 112 corresponding to width L and a subset 304 of light sources 114 corresponding to width W. The initial scan area 310 may be the entire area of ​​W×L.

[0047] However, a user may desire to crop document 104 to include a smaller area of ​​document 104. As a result, the user may touch the area of ​​touch sensor 202 above light source 1126 and the area of ​​touch sensor 202 above light source 1146. In another example, the user may swipe across the area of ​​touch sensor 202 to light sources 1121-1125 and then swipe across the area of ​​touch sensor 202 to light sources 1141-1145. As a result, using touch sensor 202, the user may activate subset 306 of light sources 112, which includes fewer light sources 112 than subset 302. Additionally, the user may activate subset 308 of light sources 114, which includes fewer light sources 114 than subset 304.

[0048] Subsets 306 and 308 may define a new scan area 312 that is smaller than initial scan area 310. As a result, when a scan job is initiated, optical scanner 106 may scan images from document 104 within scan area 312. In other words, document 104 may be cropped to scan the portion of document 104 that falls within new scan area 312.

[0049] 4 illustrates an example of selecting different scan areas of a document using touch sensors 202 on the optical arrays 108 and 110 of the present disclosure. FIG. 4 illustrates an example in which two optical arrays 108 and 110 are positioned around the perimeter of the platen glass 102.

[0050] In one embodiment, a user can select different scan areas 404, 406, and 408 by touching different areas of touch sensors 202 on light arrays 108 and 110. For example, a user may want to scan different portions of document 104 and eliminate other portions of document 104 (or prevent scanning of non-scan areas 410 and 412). For example, scan area 404 may have width w and length l1, scan area 406 may have width w and length l2, and scan area 408 may have width w and length l3.

[0051] In one embodiment, a user may define scan areas 404, 406, and 408 by touching different portions of touch sensors 202 on light arrays 108 and 110. For example, a user may touch touch sensors 202 on light source 114 in subset 402. A user may also touch light sources 1121-1122, light sources 1124-1127, and light sources 1121-1128. 13 In another embodiment, the user may define the non-scan areas 410 and 412 by touching the touch sensor 202 to deactivate the corresponding light source 1123 and light sources 1128-1129.

[0052] As a result, when the optical scanner 106 is activated, the optical scanner 106 can scan the portion of the document 104 within the scan area 404. When the optical scanner 106 moves within the non-scan area 410, the optical scanner may be deactivated. When the optical scanner 106 moves within the scan area 406, the optical scanner 106 may be reactivated to scan the portion of the document 104 within the scan area 406. The optical scanner 106 may be deactivated within the non-scan area 412, reactivated within the scan area 408, etc.

[0053] 5 illustrates an example of using touch sensors 202 on the light arrays 108 and 110 of the present disclosure to define different scan areas for different documents 104. FIG. 5 illustrates an example in which four light arrays 1081, 1082, 1101, and 1102 may be located around the perimeter of the platen glass 102. In one embodiment, the light arrays 1081 and 1082 may be on opposite sides along the length of the platen glass 102. The light arrays 1101 and 1102 may be on opposite sides along the width of the platen glass 102.

[0054] In one embodiment, four light arrays 1081, 1082, 1101, and 110 2- The platen glass is divided into four different areas 502, 504, and 50 to 6 The scan areas of different sizes may be divided into areas 502, 504, and 50 within 6 For example, light array 1081 and light array 1101 may be used to define scan areas 5101 and 5102 within region 502. Light array 1081 and light array 1102 may be used to define scan area 5104 within region 504. Light array 1082 and light array 1101 may be used to define scan area 5103 within region 506. stomach.

[0055] It should be noted that while six scan areas 5101-5106 are shown in Figure 5, any number of scan areas may be defined. Additionally, although four different light arrays are shown, two light arrays may be used to define different scan areas.

[0056] In one embodiment, documents 1041-1046 of different sizes may be placed within each area 5101-5106. As a result, when optical scanner 106 is activated, it may scan each of the different documents 1041-1046. However, through image processing, processor 118 may learn that each defined scan area 5101-5106 contains a different document. Processor 118 may then generate six different scanned images. In other words, rather than a single image containing scans of all six documents 1041-1046, processor 118 may generate six different files or scanned images for each document 1041-1046. Thus, a single scan may simultaneously scan multiple documents 1041-1046 and generate separate scanned images for each document 1041-1046 via the user-defined scan areas 5101-5106.

[0057] 6 shows a flow diagram of an exemplary method 600 for defining a scan area on a platen glass using an optical array of the present disclosure. In one embodiment, method 600 may be performed by MFD 100 or by an apparatus such as apparatus 700 illustrated in FIG. 7 and discussed below.

[0058] In one embodiment, method 600 begins at block 602. At block 604, method 600 receives a selection of parameters for a scan job. For example, a user may wish to scan a document. The user may select paper size, resolution, etc.

[0059] In one embodiment, parameters may be automatically selected by the MFD or document scanning device. For example, the original size of the document may be detected, and certain parameters such as paper size, image size, resolution, etc. may be automatically selected. For example, the MFD may have an "auto-detect" feature to detect certain parameters for a scan job.

[0060] At block 606, the method 600 determines an origin and orientation on the platen glass based on the selection of parameters for the scan job. In one embodiment, each paper size may have a specific default origin and orientation. The scan area may be approximately the same size as the paper size (e.g., length and width).

[0061] In block 608, the method 600 controls portions of the light array to define a scan area, indicate an origin, and indicate an orientation. In one embodiment, a table may be stored in memory that identifies which light sources are associated with which scan area and orientation. The MFD's processor can then control the appropriate light sources in the light array located around the perimeter of the MFD's platen glass.

[0062] In one embodiment, the light source may be controlled to be on and off. For example, an on light source may indicate the origin where the document should be placed on the glass platen, the orientation of how the document should be placed on the glass platen, and the outline of the scan area (e.g., the same as the paper size by default).

[0063] In one embodiment, the light source may be controlled to change color. For example, the light source may change from red to green. A light source emitting green light may indicate the origin where the document should be placed on the platen glass, the orientation of how the document should be placed on the platen glass, and the outline of the scan area (e.g., the same as the paper size by default).

[0064] As described above, the light sources can be dynamically controlled to define different origins, orientations, and scan areas. For example, a user may desire to scan a second document having a different paper size than a first document. The MFD may receive a selection of different parameters for the second scan job. The origin and orientation on the platen glass may be based on the selection of different parameters for the second scan job. Then, to indicate the origin and orientation, different portions or light sources of the light array may be controlled to define the scan area. For example, the second document may be wider and longer than the first document. As a result, additional light sources of the light array may be controlled to be activated to indicate the origin, orientation, and scan area of ​​the second document.

[0065] In one embodiment, the scan area may be dynamically changed using touch sensors. For example, each light array may include a touch sensor. A user can control the operation of the light sources using touch gestures (e.g., touching a touch sensor in a location above each light source or swiping to control multiple light sources with a single gesture).

[0066] For example, after a user places a document on the platen glass, the user may want to change the scan area. Rather than going through menus via the user interface, the user can simply use the touch sensors on the light array to define a new scan area.

[0067] Method 600 may receive a signal from a touch sensor associated with the light array indicating that a different portion of the light array has been selected. The scan area may then be changed according to the different portion of the light array that is selected. For example, the document may be cropped, different portions of the document may be scanned or organized, or different documents may be scanned simultaneously, as described above and shown in FIGS. 3-5. At block 610, method 600 ends.

[0068] Figure 7 depicts a high-level block diagram of a computer dedicated to performing the functions described herein. As depicted in Figure 7, the computer 700 comprises one or more hardware processor elements 702 (e.g., a central processing unit (CPU), microprocessor, or multi-core processor), memory 704, such as random access memory (RAM) and / or read-only memory (ROM), a module 705 for defining a scan area on a platen glass using an optical array, and various input / output devices 706 (e.g., storage devices including, but not limited to, tape drives, floppy drives, hard disk drives, or compact disk drives, receivers, transmitters, speakers, displays, voice synthesizers, output ports, input ports, and user input devices (keyboard, keypad, mouse, microphone, etc.)). It should be noted that while only one processor element is shown, multiple processor elements may be employed in a computer.

[0069] It should be noted that the present disclosure may be implemented in software and / or a combination of software and hardware, for example, using an application specific integrated circuit (ASIC), a programmable logic array (PLA) including a field-programmable gate array (FPGA), or a state machine deployed on a hardware device, a computer, or any other hardware equivalent, such as computer readable instructions that may be used to configure a hardware processor to perform the steps, functions, and / or operations of the methods discussed above. In one embodiment, instructions and data (e.g., a software program including computer executable instructions) for this module or process 705 for defining a scan area on a platen glass using an optical array may be loaded into memory 704 and executed by hardware processor element 702 to implement the steps, functions, or operations as discussed above.
