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

[0016] For scanning or copying functions, an MFD can expect documents to be placed in a specific location and orientation. Some MFDs may have a static indicator to identify the origin. However, many do not indicate orientation. For example, documents of different sizes may be placed in different orientations. For illustrative purposes, some documents of certain sizes may be placed portraitly, while others may be expected to be placed landscapely.

[0017] Without an indication of the proper orientation, the user may place the document on the platen glass in an incorrect orientation. After the document has been scanned, the user may realize that the document was placed in an incorrect orientation and that parts of the document are missing from the scan job.

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

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

[0020] In one embodiment, the optical array may include a touch sensor that can be used to make selected portions of the optical array active and / or inactive. The user can swipe in a first direction to make a portion of the optical array active and swipe in a second, opposite direction to make the portion of the optical array inactive. The touch sensor optical array can enable the user to select the origin and orientation of the scan job through the selection of a desired area using the touch sensor optical array. The selection may then be processed by the MFD and translated into appropriate menu selections in the user interface.

[0021] Additionally, the touch sensor light array may enable a user to easily crop a portion of a document using the touch sensor light array and to define different active scan regions on the platen glass for different documents being scanned simultaneously. As a result, the platen glass having the light array of the present disclosure can enable the scanning and / or copying of documents on the MFD to be performed more accurately and efficiently.

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

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

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

[0025] In one embodiment, the memory 120 may include instructions executed by the processor 118 to automatically detect the original size of the document 104 placed on the platen glass 102. The processor 118 may then automatically select several parameters for the scan job based on the detected size of the document 104. For example, the MFD may have an "auto-detect" function for detecting specific parameters for the scan job. While the examples described herein may refer to scan jobs, it should be noted that embodiments of this disclosure may also be applied to copy jobs.

[0026] In one embodiment, the MFD 100 may include optical arrays 108 and 110. The optical arrays 108 and 110 may be located around the outer periphery of the platen glass 102. At least one optical array 108 may be located adjacent to the platen glass 102 along the length of the outer periphery, and at least one optical array 110 may be located adjacent to the platen glass 102 along the width of the outer periphery. In other words, although Figure 1 shows an example with four optical arrays around the platen glass 102, it should be noted that two optical arrays (e.g., one optical array 108 and one optical array 110) may be deployed.

[0027] In one embodiment, the optical array 108 comprises a plurality of light sources 1121-112 n (Hereinafter, these may also be referred to as individual light sources 112 or collectively as light sources 112). In one embodiment, the optical array 110 includes a plurality of light sources 1141 to 114 m (Hereinafter, these may also be 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 source 112 may be arranged in a single line along the length of the light array 108. The light source 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 colored light sources 112 arranged alternately in a single line (e.g., green, red, green, red, etc.) or in two parallel lines. The light array 110 may similarly include two different colored light sources.

[0029] Light sources 112 and 114 can be dynamically controlled based on parameters selected for the scan job and can provide visual cues regarding the origin and orientation. The origin may be the position where the corners of document 104 should be located. The orientation may indicate whether document 104 should be placed vertically or horizontally. Light sources 112 and 114 can also be dynamically controlled to define the scan area. For example, the scan area may include boundaries that the optical scanner 106 may be active in capturing image data from document 104. By defining different scan areas, it may be possible for the user to crop document 104, scan different parts of document 104, and scan multiple different documents and documents of different sizes simultaneously, as will be discussed in more detail below and shown in Figures 3 to 5.

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

[0031] For example, a scan job with 8.5 x 11 inch paper may have its origin at the upper left corner of the platen glass 110. The default orientation may be landscape. As a result, when a user selects a scan job with 8.5 x 11 inch paper, the processor 118 can change the state of the light sources 112 and 114 to define a scan area with a landscape orientation and a size of 8.5 x 11 inches, with its origin at the upper left corner of the platen glass 102.

[0032] For example, light sources 112 and 114 may be controlled to be turned on and off, and to change color (e.g., red and green). Figure 1 shows that light sources 1121-1126 in the optical array 108 are active (e.g., turned on or changed to green), and light sources 1127-112 n This indicates that it is inactive (for example, turned off or changed to red). Light sources 1141-1145 in the optical array 110 are active, and light sources 1146-114 m It has been deactivated.

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

[0034] If the user selects a different scan job on 11x14 inch paper, the processor 118 may change the activated light sources 112 and 114. For example, for 11x14 inch paper, light sources 1121-1129 may be activated, or light sources 1141-1147 may be activated.

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

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

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

[0038] In one embodiment, the touch sensor 202 may be communicatively coupled to the processor 118. Generally, the touch sensor 202 can be any type of touch sensor. For example, the touch sensor 202 may be a capacitive touch sensor, a resistive touch sensor, and the like. The touch sensor 202 may be optically transparent so that light emitted from the light source 112 can be seen through the touch sensor 202.

[0039] In one embodiment, touching the touch sensor 202 can change the state of a light source 112 located beneath the area of ​​the touch sensor 202 that is being touched. Memory 120 can store the x and y coordinates of the touch sensor 202 and which light source 112 is associated with a particular range of x and y coordinates on the touch sensor 202. When a specific location on the touch sensor 202 is touched, a signal containing the x and y coordinates on the touched touch sensor 202 may be sent to the processor 118. The processor 118 can determine which light source 112 is associated with the x and y coordinates and change the state of the light source 112.

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

[0041] In one embodiment, a subset of light sources 112 may be controlled by 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 selecting different subsets of light sources 112 using swiping. For instance, a user may touch touch sensor 202 above light source 1121 and swipe across touch sensor 202 to above light source 1124. Then, the user may lift their finger and touch touch sensor 202 above light source 1127 and swipe across touch sensor 202 to 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 document 104 in the regions corresponding to light sources 1121 to 1124, deactivate in the regions corresponding to light sources 1125 to 1126, and reactivate to capture an image of document 104 in the regions corresponding to light sources 1127 to 1129.

[0043] Additionally, the processor 118 may automatically change parameters in the appropriate menu selection within the scan job software. In other words, the user does not need to go through menu selections in the user interface 116. Rather, the selection of a different scan orientation or scan area via the touch sensor 220 causes the processor 118 to automatically change the parameters in the menu. For example, if the user changes the scan area to accommodate 11 x 14 inch paper in landscape orientation using the touch sensor 202, the processor 118 may change the parameters of the scan job displayed in the user interface to accommodate 11 x 14 inch paper in landscape orientation.

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

[0045] Figure 3 shows an example of cropping a document 104 by selecting a specific scan area using the touch sensor 202 of the present disclosure. Figure 3 shows an example in which two optical arrays 108 and 110 are arranged around the outer periphery of the platen glass 102.

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

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

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

[0049] Figure 4 shows an example of using touch sensors 202 on optical arrays 108 and 110 of the present disclosure to select different scanning areas of a document. Figure 4 shows an example in which the two optical arrays 108 and 110 are arranged around the outer periphery of a platen glass 102.

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

[0051] In one embodiment, the user may define scan areas 404, 406, and 408 by touching different parts of the touch sensor 202 on the optical arrays 108 and 110. For example, the user may touch the touch sensor 202 on the light source 114 within subset 402. The user may also touch light sources 1121-1122, light sources 1124-1127, and light sources 1121-112 13 The user may touch the touch sensor 202 above. In another embodiment, the user may define non-scan areas 410 and 412 by touching the touch sensor 202 to deactivate the corresponding light sources 1123 and 1128-1129.

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

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

[0054] In one embodiment, four optical arrays 1081, 1082, 1101, and 110 2- The platen glass may be divided into four different regions 502, 504, 506, and 508. Scan regions of different dimensions may be defined within regions 502, 504, 506, and 508. For example, optical arrays 1081 and 1101 may be used to define scan regions 5101 and 5102 within region 502. Optical arrays 1081 and 1102 may be used to define scan region 5104 within region 504. Optical arrays 1082 and 1101 may be used to define scan region 5103 within region 506, and optical arrays 1082 and 1102 may be used to define scan regions 5105 and 5106 within region 508.

[0055] Six scan regions 5101-5106 are shown in Figure 5, but note that any number of scan regions may be defined. Additionally, four different optical arrays are shown, but two optical arrays may be used to define different scan regions.

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

[0057] Figure 6 shows a flowchart 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 an MFD 100 or by an apparatus such as the apparatus 700 illustrated in Figure 7 and discussed below.

[0058] In one embodiment, method 600 begins in block 602. In block 604, method 600 receives a selection of parameters for a scan job. For example, the user may want to scan a document. The user can 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, or several parameters such as paper size, image size, and resolution may be automatically selected. For example, the MFD may have an "auto-detection" function for detecting specific parameters of a scan job.

[0060] In block 606, method 600 determines the 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 (e.g., length and width).

[0061] In block 608, method 600 controls a portion of the optical array to define a scan region, indicate an origin, and indicate an orientation. In one embodiment, a table may be stored in memory that identifies which light source is associated with which scan region and orientation. The MFD processor can then control the appropriate light source within the optical array located around the outer periphery of the platen glass of the MFD.

[0062] In one embodiment, the light source may be controlled to be on and off. For example, when the light source is on, it may indicate the origin where the document should be placed on the platen glass, the orientation in which the document should be placed on the platen glass, and the contour of the scanning area (for example, 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 in which the document should be placed on the platen glass, and the contour of the scanning area (for example, the same as the paper size by default).

[0064] As described above, the light source can be dynamically controlled to define different origins, orientations, and scan areas. For example, a user may want to scan a second document having a different paper size than the 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, different parts of the light array or light sources may be controlled to define the scan area in order to indicate the origin and orientation. For example, the second document may be wider and longer than the first document. As a result, additional light sources in 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 scanning area may be dynamically changed using a touch sensor. For example, each light array may include a touch sensor. The user can control the operation of the light sources using touch gestures (e.g., touching the touch sensor at a position 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, they may want to change the scanning area. Instead of going through a menu via the user interface, the user can simply define a new scanning area using a touch sensor on the optical array.

[0067] Method 600 can receive a signal from a touch sensor associated with the optical array indicating that a different portion of the optical array has been selected. The scan area can then be modified according to the selected different portion of the optical array. For example, a document may be cropped, different portions of a document may be scanned or organized, or different documents may be scanned simultaneously, as described above and shown in Figures 3 to 5. In block 610, Method 600 terminates.

[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), a microprocessor, or a multicore processor), memory 704, e.g., random access memory (RAM) and / or read-only memory (ROM), a module 705 for defining scan areas 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, speech synthesizers, output ports, input ports, and user input devices (keyboards, keypads, mice, microphones, etc.)). Note that although only one processor element is shown, a computer may employ multiple processor elements.

[0069] It should be noted that this disclosure may be implemented in software and / or in combination of software and hardware, for example, using computer-readable instructions that may be used to configure a hardware processor to perform the steps, functions, and / or operations of the disclosed method, including, for example, application-specific integrated circuits (ASICs), programmable logic arrays (PLAs) including field-programmable gate arrays (FPGAs), or state machines, computers, or any other hardware equivalents deployed on hardware devices. In one embodiment, instructions and data for the module or process 705 for defining a scan region on a platen glass using an optical array (e.g., a software program including computer-executable instructions) are loaded into memory 704 and executed by a hardware processor element 702 to implement the steps, functions, or operations discussed above. Furthermore, when a hardware processor executes instructions and performs an "action," this may include the hardware processor performing the action directly and / or facilitating, directing, or cooperating with another hardware device or component (such as a coprocessor) to perform an action.

[0070] A processor that executes computer-readable instructions or software instructions related to the above method may be recognized as a programmed processor or a specialized processor. Thus, the module 705 (including the corresponding data structure) for defining a scan area on a platen glass using the optical array of the present disclosure may be stored in a tangible or physical (broadly speaking, non-temporary) computer-readable storage device or medium, such as volatile memory, non-volatile memory, ROM memory, RAM memory, magnetic or optical drives, devices, or diskettes. More specifically, the computer-readable storage device may comprise any physical device that provides the ability to store information such as data and / or instructions accessed by a processor or computing device such as a computer or application server.
