Systems and methods herein generally relate to systems and methods that are used to scan documents, combine the scanned pages into n-up sheets, and output electronic files containing the n-up sheets.
When processing documents electronically or during printing, it can often be useful to arrange multiple scanned pages on a single sheet because doing so presents more information per sheet and can potentially reduce file size and/or the number of sheets printed. This processing is often referred to as “n-up” processing to represent the different number (n) of pages that can be included on each sheet. For example, 2 pages per sheet is referred to as 2-up and such pages are generally positioned side-by-side on the sheet, 4 pages per sheet is referred to as 4-up and such pages are generally position in the four quadrants of the sheet, etc., and the terminology “n-up” captures all numbers of pages per sheet and such sheets are generally arranged in an organized manner and evenly spaced from one another on the sheets.
One issue with n-up sheet processing is decreased resolution of the individual pages on each sheet. In common n-up processing, because each page represented takes up a smaller portion of the sheet, the resolution of each page is intentionally reduced by the n-up sheet processing apparatus. For example, in 4-up processing, the resolution of each sheet may be reduced (e.g., to 25%, 50%, etc., or higher or lower, of the page's original resolution). While this is helpful for maintaining reasonable file sizes and for making print processing less resource intensive when creating bitmaps, etc., it can have the disadvantage of reducing readability or the appearance of each individual page on the sheet.
This is especially true when n-up processing is performed to create electronic files because the sheets may not be printed, but instead such files may only be viewed. When such electronic files are enlarged during viewing, the decreased resolution can impact the user experience because of the reduced readability or appearance resulting from the reduced resolution.
Therefore, there is a tradeoff between resolution and file size during n-up sheet processing, in that increasing the resolution will also increase file size making such larger files harder to store and transmit. Attempts may be made to balance the competing interest between resolution and file size so that the decreased resolution may not be easily perceived by the user; however, no current solutions address the issue of resolution in n-up processing adequately. Such attempts have historically met a mixed reception because often the resolution and is decreased too much by these automated processes or the file sizes are still too large for easy storage or transmission.
In order to address such issues, various methods herein receive, into a user interface of a scanning system, an instruction to combine multiple scanned pages into one or more n-up sheets. In response to receiving the instruction to combine multiple scanned pages, these methods output a resolution field from the user interface. The methods then receive what is referred to herein as a user-set resolution for the scanned pages on the n-up sheets into the resolution field. This user-set resolution can be an exact resolution or a minimum resolution which the scan resolutions must be at or above. In some methods herein, the user interface can also provide input fields to supply the quantity of the scanned pages to include in each n-up sheet, the total number of pages to be scanned, etc.
In some optional methods herein, the process of outputting the resolution field can include outputting individual scanned page resolution fields, potentially allowing each page to be scanned at a different resolution. In response, these methods can receive, into each of the individual scanned page resolution fields, what is referred to herein as page-specific resolution settings corresponding to one or more of the scanned pages (the scanned pages that receive page-specific resolution settings are referred to herein as individual resolution pages). Therefore, under this option, the one or more individual resolution pages can have their own page-specific resolution settings, while the remainder of the pages (referred to herein as remaining pages) will be scanned and processed according to the initially established user-set resolution. Because of this option, after the process of combining the scanned pages together, the scanned pages within the n-up sheets can have different resolutions relative to one another, with each of the individual resolution scanned pages being at a potentially different page-specific resolution setting, with the remaining pages being at the user-set resolution.
In other options, in response to the receipt of the user-set resolution and/or the page-specific resolution settings, these methods can output the expected file size of the n-up sheets (e.g., given the input resolution setting, the number of pages per n-up sheet, and number of n-up sheets, etc.) to allow the users to easily see how their resolution setting(s) affect overall file size. This allows the user to iteratively move the user-set resolution (and/or the page-specific resolution settings) up or down to stay within a desired file size.
After this, the methods herein scan the scanned pages at the user-set resolution and/or the page-specific resolution settings using a scanner of the scanning system. With these methods a processor of the scanning system is used to combine the scanned pages together into the n-up sheets at the user-set resolution (and/or the page-specific resolution settings) and the processor outputs the n-up sheets in an electronic file. Commencing with the final scanning process, the user's resolution(s) for the scanned pages remains unaltered and such resolutions are not reduced.
Other methods herein similarly receive, into a user interface of a scanning system, an instruction to combine multiple scanned pages into one or more n-up sheets. However, in response to receiving the instruction to combine multiple scanned pages, these methods output a file size field from the user interface. In response, these methods receive what is preferred to herein as a user-set file size into the file size field (which can be a set file size or a maximum file size that the n-up sheet file is to be at or below).
In some methods herein, the user interface can again provide input fields to supply the quantity of the scanned pages to include in each n-up sheet, the total number of pages to be scanned, etc. Here, these methods calculate, using the processor, what is preferred to herein as a calculated resolution of the scanned pages on the n-up sheets based on factors such as the user-set file size, the quantity of the scanned pages included in each n-up sheet, the total number of pages to be scanned, etc. Further, these methods output, through the user interface, this calculated resolution in response to receiving the user-set file size to provide the user with the option to adjust the user-set file size until a calculated resolution that is acceptable to the user is reached.
In some options herein, the methods can again output individual scanned page resolution fields, potentially allowing each page to be scanned at a different resolution. In response, these methods can receive, into each of the individual scanned page resolution fields, a page-specific resolution settings corresponding to one or more of the scanned pages (individual resolution pages). Therefore, under this option, the individual resolution page(s) can have their own page-specific resolution settings.
However, in these options, after receiving the page-specific resolution setting, the resolution of the remaining pages may change beyond the user's expectation. Therefore, the methods herein recalculate the previous calculated resolution for the remaining scanned pages not included in the individual scanned page(s) using the processor. The recalculation of the previous calculated resolution produces a “recalculated resolution” that is based on the page-specific resolution setting for the individual scanned page resolution pages, the user-set file size, the quantity of the scanned pages included in each n-up sheet, the total number of pages to be scanned, etc.
Here again these methods can optionally output, through the user interface, this recalculated resolution for the remaining pages in response to receiving the page-specific resolution setting(s) to again provide the user with the option to iteratively adjust the page-specific resolution setting(s) until a recalculated resolution that is acceptable to the user is reached.
With this, the methods herein scan the scanned pages at the user-set resolution and/or the page-specific resolution settings using a scanner of the scanning system. With these methods a processor of the scanning system is used to combine the scanned pages together into the n-up sheets at the user-set resolution (and/or the page-specific resolution settings). In optional methods that allow the page-specific resolution settings, after the process of combining the scanned pages together, the scanned pages within the n-up sheets can have different resolutions relative to one another, with the individual resolution scanned pages being at the page-specific resolution setting input by the user, and the remaining pages being at the recalculated resolution. Again, during the scanning and combining processes the resolution of the scanned pages is not changed. These methods output from the processor the n-up sheets in an electronic file.
Various systems and apparatuses herein include, among other components, a processor, and a scanner and a user interface operatively connected to the processor. The user interface is adapted to receive an instruction to combine multiple scanned pages into one or more n-up sheets. The user interface is adapted to output a resolution field in response to receiving the instruction to combine multiple scanned pages. The user interface is also adapted to receive, into the resolution field, a user-set resolution of the scanned pages on the n-up sheets. This user-set resolution can be an exact resolution or a minimum resolution which the scan resolutions must be at or above. The user interface can also be adapted to provide input fields to supply the quantity of the scanned pages to include in each n-up sheet, the total number of pages to be scanned, etc.
In some options herein, the user interface is adapted to additionally output individual scanned page resolution fields, potentially allowing each page to be scanned at a different resolution. In response, the user interface is adapted to receive, into each of the individual scanned page resolution fields, page-specific resolution settings corresponding to one or more of the scanned pages (individual resolution pages). Therefore, under this option, the individual resolution pages to be scanned (or groups of pages to be scanned) can have their own page-specific resolution settings, while the remaining pages will be scanned and processed according to the user-set resolution for all the scanned pages. Because of this option, after the process of combining the scanned pages together, the scanned pages within the n-up sheets can have different resolutions relative to one another, with each of the individual resolution scanned pages being at a potentially different page-specific resolution setting, with the remaining pages being at the user-set resolution.
In other options, in response to the receipt of the user-set resolution and/or the page-specific resolution settings, the user interface can be adapted to output the expected file size of the n-up sheets given the input resolution setting, the number of pages per n-up sheet, and number of n-up sheets, as calculated by the processor to allow the users to easily see how their resolution settings affect overall file size. This allows the user to iteratively move the user-set resolution (and/or the page-specific resolution settings) up or down to stay within a desired file size.
The scanner is adapted to scan the scanned pages at the user-set resolution and/or the page-specific resolution settings. The processor is adapted to combine the scanned pages together into the n-up sheets at the user-set resolution (and/or the page-specific resolution settings), and the processor is adapted to output the n-up sheets in an electronic file. In the scanning and combining processing, the user-set resolution (and/or the page-specific resolution settings) for the scanned pages remains unaltered.
In other system and apparatus embodiments herein, the user interface is again adapted to receive an instruction to combine multiple scanned pages into one or more n-up sheets. However, with these embodiments, the user interface is adapted to output a file size field in response to receiving the instruction to combine multiple scanned pages. The user interface is adapted receive a user-set file size into the file size field (which can be a set file size or a maximum file size that the n-up sheet file is to be at or below).
Again, the user interface can also be adapted to provide input fields to supply the quantity of the scanned pages to include in each n-up sheet, the total number of pages to be scanned, etc. Here, the processor is adapted to calculate a “calculated resolution” of the scanned pages on the n-up sheets based on the user-set file size, the quantity of the scanned pages included in each n-up sheet, the total number of pages to be scanned, etc. The user interface can be adapted to output this calculated resolution in response to receiving the user-set file size to provide the user with the option to iteratively adjust the user-set file size until a calculated resolution that is acceptable to the user is reached.
As with the previously described embodiments, in these embodiments the user interface is again adapted to output individual scanned page resolution fields. Similarly, the user interface is adapted to receive, into each of the individual scanned page resolution fields, a page-specific resolution setting for at least one corresponding individual resolution page. However, in these embodiments, after receiving the page-specific resolution setting, the processor is adapted to recalculate the previous calculated resolution for the remaining scanned pages not included in the individual scanned page(s). The recalculation of the previous calculated resolution produces a “recalculated resolution” that is based on the page-specific resolution setting for the individual scanned page resolution pages, the user-set file size, the quantity of the scanned pages included in each n-up sheet, the total number of pages to be scanned, etc.
The scanner is adapted to scan the scanned pages at the calculated resolution (or at the page-specific resolution setting for the individual scanned page resolution pages and the recalculated resolution for the remaining scanned pages). The processor is adapted to combine the scanned pages together into the n-up sheets at the calculated resolution(s). Further, the processor is adapted to output the n-up sheets in an electronic file. During the scanning and combining processing, the calculated resolution(s) of the scanned pages is unaltered.
These and other features are described in, or are apparent from, the following detailed description.
Various exemplary systems and methods are described in detail below, with reference to the attached drawing figures, in which:
As mentioned above, in n-up processing that reduces page size and places multiple pages on each sheet, there is a tradeoff between resolution and file size because increasing the resolution will also increase file size, making such files harder to store and transmit. In view of this, the systems and methods herein interact with users to achieve a balance of resolution and file size that accommodates the desires of the user.
In response to receiving the instruction to combine multiple scanned pages, in item 102 these methods output a resolution field from the user interface. For example, as shown in
In item 104, the methods receive what is referred to herein as a “user-set resolution” for all the scanned pages on the n-up sheets into the resolution field 250. This user-set resolution can be an exact resolution or a minimum resolution which the scan resolutions must be at or above.
In some optional methods herein, the process of outputting the resolution field in item 102 can include outputting individual scanned page resolution fields (that are shown as items 252 in
In response, in item 106 these methods can receive, into each of the individual scanned page resolution fields 252, what is referred to herein as page-specific resolution settings corresponding to one or more of the scanned pages (that are referred to herein as individual resolution pages). Therefore, under this option, the one or more individual resolution pages can have their own page-specific resolution settings, while the remainder of the pages (referred to herein as remaining pages) will be scanned and processed according to the initially established user-set resolution. Because of this option, after the process of combining the scanned pages together (see item 116 discussed below) the scanned pages within the n-up sheets can have different resolutions relative to one another, with each of the individual resolution scanned pages being at a potentially different page-specific resolution setting, with the remaining pages remaining at the user-set resolution.
In some methods herein, as shown in item 108, the user interface can also provide input fields (shown as items 254 and 256 in
In other options, in response to the receipt of the user-set resolution and/or the page-specific resolution settings, in item 110 these methods can calculate the expected file size of the n-up sheets (given the input resolution setting, the number of pages per n-up sheet, and number of n-up sheets). For example, when calculating the expected file size, the methods and devices herein multiply the storage requirement for each page (e.g., dpi×page size (in dots, for example) x estimated storage requirement per dot) by the number of n-up pages per sheet and add to their value other storage requirements per sheet (e.g., header, metadata, sheet layout/formatting data, etc.) to determine the total electronic file storage requirements per sheet. The total storage requirements per sheet is then multiplied by the number of sheets that will be necessary (e.g., total number of pages to be scanned/number of pages per sheet). Other similar calculations are made to determine the expected file size in item 110.
The expected file size is output in item 112 (see item 258 in
From here, the user can optionally return to the resolution settings (see item 260 in
With this, in item 114 the methods herein scan the scanned pages at the user-set resolution and/or the page-specific resolution setting(s) using a scanner of the scanning system (for details, see the system and apparatus embodiments discussed below). More specifically, commonly known (and machine specific) screen instructions are output that guide the user through the necessary steps (e.g., loading physical pages to be scanned in the appropriate machine location, orientation, and order; pressing appropriate buttons; etc.) in order to allow the scanner to optically scan the physical pages and create electronica scanned pages.
While an acceptable estimate of the file size can be calculated without actually scanning the document based on the user-set resolution, the file size may vary depending on the content of the document. Therefore, in item 116 these methods can output the actual file size calculated with the actual scan data to the user through the user interface, which will be more accurate than the estimate produced in item 110. A screen similar to
The electronically scanned pages are maintained in memory until they can be combined by the processor into the n-up sheets. With these methods a processor of the scanning system is used to combine the scanned pages together into the n-up sheets at the user-set resolution (and/or the page-specific resolution settings) in item 118 without altering the resolution used in the final scanning process 114.
In other words, the multiple scanned pages within each n-up sheet produced during the combining process in item 118 have the same resolution produced by the final scanning of the individual pages in item 114. This can increase scanning efficiency (reduce the time needed for scanning and the accompanying resource utilization) by having the scanning equipment automatically perform scanning at only the resolution needed. In contrast, scanning can be performed at a higher resolution and then the resolution of the images can be reduced by the processor to the user-set resolution. In item 120, the processor outputs the n-up sheets in an electronic file format. In the processing in items 114-120, the user's resolution(s) for the scanned pages remains unaltered once finally set by the user.
Similar to the above, in item 136 the user interface can again provide input fields to supply the quantity of the scanned pages to include in each of the n-up sheets, the total number of pages to be scanned, etc., and these are shown as items 272 and 274 in
With this information, in item 138 these methods calculate (using the processor) a “calculated resolution” of the scanned pages on the n-up sheets based on the user-set file size, the quantity of the scanned pages included in each n-up sheet, the total number of pages to be scanned, etc. For example, when calculating the calculated resolution, the methods and devices herein determine the number of sheets (quantity of scanned pages divided by n-up pages per sheet) and subtract the other storage requirements per sheet (e.g., header, metadata, sheet layout/formatting data, etc.) from the user-set file size to find the amount of storage available for the n-up pages on the sheets. The amount of storage available for the n-up pages on the sheets is then divided by the number of n-up pages to be scanned to determine the amount of storage available per n-up page. The calculated resolution is then determined by dividing the amount of storage available per n-up page by the page size (in dots, for example) after being multiplied by the estimated storage requirements per dot (calculated resolution=per page storage/(page size×storage requirement per dot)). Other similar calculations are made to determine the calculated resolution size in item 138.
Further, in item 140 these methods output, through the user interface, this calculated resolution that is shown in
As with the previously described methods, these methods can also output individual scanned page resolution fields that are shown as item 280 in
However, in these options, after receiving the page-specific resolution setting, the methods recalculate the previous calculated resolution for the remaining scanned pages not included in the individual scanned page(s) using the processor in item 144. The recalculation of the previous calculated resolution produces a “recalculated resolution” that is based on the page-specific resolution setting for the individual scanned page resolution pages, the user-set file size, the quantity of the scanned pages included in each n-up sheet, the total number of pages to be scanned, etc. This calculation is similar to the calculation presented above in item 138; however, here the amount of storage available for the remaining pages is further reduced by the amount of storage the individual resolution pages will consume.
Here again these methods can optionally output, through the user interface in item 146, the recalculated resolution in response to receiving the page-specific resolution setting(s) and this is shown in
Alternatively, as shown in item 286 in
While an acceptable estimate of the resolution can be calculated without actually scanning based on the file size selected, the resolution may vary depending on the content of the document. Therefore, in item 150 these methods can output the actual resolution calculated with the actual scan data, which will be more accurate than the estimate produced in item 138. A screen similar to
These methods use the processor to combine the scanned pages together into the n-up sheets at the user-set resolution (and/or the page-specific resolution settings) in item 150. In optional methods that allow the page-specific resolution settings, after the process of combining the scanned pages together in item 150, the scanned pages within the n-up sheets can have different resolutions relative to one another, with the individual resolution scanned pages being at the page-specific resolution setting input by the user, and the remaining pages being at the recalculated resolution. The methods output from the processor the n-up sheets in an electronic file in item 152. In this processing, the final user-set resolution(s) for the scanned pages remains unaltered.
As shown in
The input/output device 214 is used for communications to and from the computerized device 200 and comprises a wired device or wireless device (of any form, whether currently known or developed in the future). The tangible processor 224 controls the various actions of the computerized device. A non-transitory, tangible, computer storage medium device 210 (which can be optical, magnetic, capacitor based, etc., and is different from a transitory signal) is readable by the tangible processor 224 and stores instructions that the tangible processor 224 executes to allow the computerized device to perform its various functions, such as those described herein. Thus, as shown in
The one or more printing engines 240 are intended to illustrate any marking device that applies a marking material (toner, inks, etc.) to continuous media or sheets of media, whether currently known or developed in the future and can include, for example, devices that use a photoreceptor belt or an intermediate transfer belt, or devices that print directly to print media (e.g., inkjet printers, ribbon-based contact printers, etc.).
Therefore, various systems and apparatuses herein include, among other components, a processor 224, and a scanner 232 and a user interface 212 operatively connected to the processor 224. The user interface 212 is adapted to receive an instruction to combine multiple scanned pages into one or more n-up sheets. The user interface 212 is adapted to output a resolution field in response to receiving the instruction to combine multiple scanned pages. The user interface 212 is also be adapted to receive, into the resolution field, a user-set resolution of the scanned pages on the n-up sheets. This user-set resolution can be an exact resolution or a minimum resolution which the scan resolutions must be at or above. The user interface 212 can also be adapted to provide input fields to supply the quantity of the scanned pages to include in each n-up sheet, the total number of pages to be scanned, etc.
In some options herein, the user interface 212 is adapted to additionally output individual scanned page resolution fields, potentially allowing each page to be scanned at a different resolution. In response, the user interface 212 is adapted to receive, into each of the individual scanned page resolution fields, page-specific resolution settings corresponding to one or more of the scanned pages (individual resolution pages). Therefore, under this option, the individual resolution pages to be scanned (or groups of pages to be scanned) can have their own page-specific resolution settings, while the remaining pages will be scanned and processed according to the user-set resolution for all the scanned pages. Because of this option, after the process of combining the scanned pages together, the scanned pages within the n-up sheets can have different resolutions relative to one another, with each of the individual resolution scanned pages being at a potentially different page-specific resolution setting, with the remaining pages being at the user-set resolution.
In other options, in response to the receipt of the user-set resolution and/or the page-specific resolution settings, the user interface 212 can be adapted to output the expected file size of the n-up sheets given the input resolution setting, the number of pages per n-up sheet, and number of n-up sheets, as calculated by the processor 224 to allow the users to easily see how their resolution settings affect overall file size. This allows the user to iteratively move the user-set resolution (and/or the page-specific resolution settings) up or down to stay within a desired file size.
The scanner 232 is adapted to scan the scanned pages at the user-set resolution and/or the page-specific resolution settings. The processor 224 is adapted to combine the scanned pages together into the n-up sheets at the user-set resolution (and/or the page-specific resolution settings), and the processor 224 is adapted to output the n-up sheets in an electronic file. In the scanning and combining processing, the user-set resolution (and/or the page-specific resolution settings) for the scanned pages remains unaltered.
In other system and apparatus embodiments herein, the user interface 212 is again adapted to receive an instruction to combine multiple scanned pages into one or more n-up sheets. However, with these embodiments, the user interface 212 is adapted to output a file size field in response to receiving the instruction to combine multiple scanned pages. The user interface 212 is adapted receive a user-set file size into the file size field (which can be a set file size or a maximum file size that the n-up sheet file is to be at or below).
Again, the user interface 212 can also be adapted to provide input fields to supply the quantity of the scanned pages to include in each n-up sheet, the total number of pages to be scanned, etc. Here, the processor 224 is adapted to calculate a “calculated resolution” of the scanned pages on the n-up sheets based on the user-set file size, the quantity of the scanned pages included in each n-up sheet, the total number of pages to be scanned, etc. The user interface 212 can be adapted to output this calculated resolution in response to receiving the user-set file size to provide the user with the option to iteratively adjust the user-set file size until a calculated resolution that is acceptable to the user is reached.
As with the previously described embodiments, in these embodiments the user interface 212 is again adapted to output individual scanned page resolution fields. Similarly, the user interface 212 is adapted to receive, into each of the individual scanned page resolution fields, a page-specific resolution setting for at least one corresponding individual resolution page. However, in these embodiments, after receiving the page-specific resolution setting, the processor 224 is adapted to recalculate the previous calculated resolution for the remaining scanned pages not included in the individual scanned page(s). The recalculation of the previous calculated resolution produces a “recalculated resolution” that is based on the page-specific resolution setting for the individual scanned page resolution pages, the user-set file size, the quantity of the scanned pages included in each n-up sheet, the total number of pages to be scanned, etc.
The scanner 232 is adapted to scan the scanned pages at the calculated resolution (or at the page-specific resolution setting for the individual scanned page resolution pages and the recalculated resolution for the remaining scanned pages). The processor 224 is adapted to combine the scanned pages together into the n-up sheets at the calculated resolution(s). Further, the processor 224 is adapted to output the n-up sheets in an electronic file. During the scanning and combining processing, the calculated resolution(s) of the scanned pages is unaltered.
