Eye marks in image processing

[0002] The printing industry often has used large sheets of print media to print several images, such as photographs, on a sheet. This allows a print device to print the several images in a single print cycle, thereby reducing the amount of wear on the device, among other things. However, once the images are printed, they then need to be separated from each other. Often times the separation of the images is accomplished by one or more cutting blades that slice the material between two or more images, thereby separating them from each other.

[0003] Additionally, the industry has utilized the use of a hole punch to mark a sheet of material with a hole which indicates where the sheet is to be cut in order to separate the images. These holes, indicating a cut position, are often referred to as cut marks. Traditionally, a plurality of images were placed serially on a web of print media with a cut mark punched in the space between two images. The web was then run through a cutting machine that would automatically detect each cut mark and would cut the web where each hole was positioned thereon.

[0004] More recently, some proposed techniques have provided single monochrome printed cut marks instead of punched holes. This allowed for printers to be utilized without the use of a punch mechanism, thereby eliminating a step in the printing process. However, there are several drawbacks to this technique.

[0005] For example, it is often difficult to distinguish between a cut mark and a feature within an image. Additionally, tears in the print media, splice marks, and debris, among others, on the surface of the print media can falsely trigger the cutting mechanism, which leads to wasted print media, excess wear on the machinery, and wasted time.

[0006] Another problem with this technique is that the mark might be lightly formed by the print device and, therefore, not detectable by the mark sensors, thereby leaving two images connected together. This can lead to a waste of resources by requiring the manual separation of the images.

[0007] Cut marks have also been used to convey information. In order to convey information, the punched cut marks were still positioned between two adjacent images, but the location within the space was alternated between two positions. For instance, information was conveyed in a binary pattern wherein a cut mark positioned on one side of the web was a 0 and wherein a cut mark positioned on the other side was a 1. However, this method of conveying information was slow, since the space between each image only had one cut mark and, therefore, only one bit of information could be conveyed with each image.

DETAILED DESCRIPTION

[0030]
FIG. 1A illustrates an example of an embodiment of an eye mark according to the teachings of the present invention. The embodiment of FIG. 1A includes an eye mark 100 having two distinct sections 101-1 to 101-2. In various embodiments, eye marks of the present invention can include one or more sections, the invention is not limited to two distinct sections.

[0031] In various embodiments of the present invention, eye marks have at least two characteristics. Various types and the various number of characteristic are applicable to embodiments of the present invention. By way of example and not by way of limitation, suitable types of characteristics include, but are not limited to, colors, locations, shapes, sizes, widths, binary coding, combinations of one or more characteristics, and the like.

[0032] The embodiment illustrated in FIG. 1A has two sections, 101-1 and 101-2, with each section having one or more unique characteristics. For instance, sections 101-1 and 101-2 are different colors and are each in a different position with respect to each other and also with respect to the section's location on a print media. Each of these distinguishing characteristics can allow each eye mark, formed by one or more of these sections, to be differentiated from other eye marks and/or other print media content, e.g. images. Therefore, each eye mark can impart a meaning that is different from eye marks having one or more sections with other characteristics. Further, when any number or combination of sections, e.g. 101-1 and 101-2, is utilized, the number of meanings, or encodable information increases.

[0033] By way of example and not by way of limitation, the embodiments of FIG. 1A can include a choice of different colors, such as Cyan, Magenta, Yellow (CMY), and the like, for application in each of the two sections, 101-1 and 101-2, in order to provide the one or more unique characteristics. A choice of a certain color in a given section, 101-1 and 101-2, (e.g. location) with respect to a choice of certain colors in another section, combination of sections and/or with respect to a location on a print media is used in various embodiments to encode information and/or identify the eye mark 100. For instance, when the color cyan is present in section 101-1, an eye mark 100 can have a meaning attributable to that color in that position on the print media. When the color Magenta is present in section 101-2, an eye mark 100 can have a meaning attributable to that color in that position on the print media. Thus, individual colors in individual sections can provide respective first meanings.

[0034] Additionally, when two or more color sections, e.g. sections 101-1 and 101-2, are coordinated the combination of the two colored sections can provide additional meanings, e.g. encoded information. That is, with the combination of particular colors, such as the color Cyan in section 101-1 and the color Magenta in section 101-2, an eye mark 100 can also provide a second meaning.

[0035] In various embodiments, more combinations can be created by changing the positions of the sections 101-1 and 101-2 with respect to each other. For example, more combinations can be created by orienting the sections 101-1 and 101-2 side by side (horizontally and/or vertically), above and below one another (horizontally and/or vertically), and well as by spacing apart the positions of the sections on a print media. The invention is not so limited. In various embodiments, as discussed in more detail below, more combinations are afforded by having more than two sections having different characteristics.

[0036] In various embodiments utilizing two or more color sections, the two or more color sections can be arrayed such that sensors can read the sections in parallel and thereby interpret meaning and/or information from the encoded eye marks at substantially the same time. By way of example and not by way of limitation, in the embodiment of FIG. 1A the two color sections 101-1 and 101-2 are aligned such that two sensors aligned above the color sections, 101-1 and 101-2, can sense a presence and/or absence of color within a section of the eye mark 100 as the eye mark 100 passes under the sensors.

[0037]
FIG. 1B illustrates an embodiment of an eye mark 110 having a combination of three color sections 111-1, 111-2, and 111-3. In the case illustrated by FIG. 1B, the combination of three color sections can provide an array of possible combinations. In binary terms (2N), 8 bits of information can be encoded in eye mark 110. In various embodiments, each combination is capable of being assigned one or more meanings. As those skilled in the art will appreciate from this disclosure, various color(s) and or monochrome embodiments are considered within the scope of the present invention.

[0038] The embodiment of FIG. 1C illustrates another embodiment of an eye mark 120 according to the teachings of the present invention. In the embodiment of FIG. 1C, two different types of sections, 121 and 122, are illustrated for use as an eye mark 120. A first section 121 includes a color section 121 which can be encoded with various colors for various meanings. A second section 122 includes a monochrome, binary bit section 122. In the embodiment of FIG. 1C, the binary bit section 122 includes 3 bits which can be encoded, in a monochrome manner or otherwise, with various meanings. The invention, however, is not so limited. Further, as described above, other combinations can be created by orienting the sections 121 and 122 side by side (horizontally and/or vertically), above and below one another (horizontally and/or vertically), and well as by spacing apart the positions of the sections on a print media. Thus, FIG. 1C illustrates an embodiment of an eye mark 120 having a combination of a color section 121 and a binary bit section 122. The use of one or more binary bit sections, e.g. 122, can allow for the communication of information through the serial reading of the bits by a sensor, wherein one bit is read after another in series.

[0039] As shown in FIG. 1C, the combination of a single color section 121 with a single binary section 122 allows different meanings for each binary bit combination with each color utilized. For instance, when used with the color cyan, an eye mark 120 can have meanings attributable to each bit and combination of bits in the binary bit structure of binary section 122. In the case of a three bit binary structure, such as that shown in the binary bit section 122 of FIG. 1C, the structure can have eight different combinations, representing various encoded information, for each particular color associated therewith in color section 121.

[0040]
FIG. 1D illustrates another example of an embodiment of an eye mark according to the teachings of the present invention. The embodiment of FIG. 1D includes an eye mark 130 having six distinct sections 131-1 to 131-3 and 132-1 to 132-3. In the embodiment of FIG. 1D, sections 131-1, 131-2, and 131-3 are all different color sections and are each in a different position with respect to each other and with respect to location on a print media. With respect to sections 132-1, 132-2, and 132-3, these sections each include a binary bit structure, with each bit location carrying a different meaning or purpose. The various embodiments shown in FIGS. 1A-1D provide an array of possible combinations for encoding information and/or identifying eye marks.

[0041] The eye marks included within of the present invention can contain encoded instructions to perform a variety of functions with respect to one or more images, content, and print media upon which the images, content, and/or eye marks are printed. The various embodiments for the eye marks themselves can be used to verify that a mark is an eye mark and not a false mark such as a piece of debris, content in an image, or the like. Further, the various embodiments for the eye marks can also provide information, such as BCD coding, spread identity coding, print finish coding, beginning/end of a set of images, and the like, as will be known and understood by those of ordinary skill in the art upon reading this disclosure. The invention is not so limited.

[0042] The various embodiments for eye marks, described herein, can be utilized to provide information in the form of one or more process instructions. For example, eye marks can provide one or more instructions to indicate where a cutting device is to cut print media. Further, eye marks can instruct a device to perform an operation on print media. For example, such operations include moving one or more images, adding a feature to one or more images, such as a matte or glossy finish, or sorting or collating one or more images, among others.

[0043] As stated above, a single section, such as 101-1 of FIG. 1A, can be utilized to provide instructions for one or more functions, e.g. to indicate where a device is to cut a print medium or to provide information such as an instruction on how to operate on the print medium. When utilizing a single section, the eye mark can be utilized to distinguish one piece of information or instruction from the next by using marks having different characteristics, such as different colors and/or different binary bit values, among others. Additionally, the marks can be located in different positions within an area between two images. As stated above, the change in location can also act as a characteristic to differentiate one mark from the next.

[0044] When utilizing multiple sections, such as is the case with the embodiments of FIGS. 1A-1D, the combinations of characteristics can provide a large number of possible meanings. Many different types of information and/or instructions can be encoded within one or more various eye mark embodiments. For example, an eye mark can be encoded with information by linking information such as instructions to a specific configuration of the one or more sections of an eye mark. For example information can include, an order number, batch number, spread identity code, and BCD coding, among others. Examples of instructions that can be provided include, beginning/end of a print job, beginning/end of an order, beginning/end of a batch, beginning/end of a waste area, beginning/end of a paper splice, beginning/end of a calibration function, instruction to back print, print finishing instructions, and slitter control instructions, among others as the same will be appreciated by one of ordinary skill in the art.

[0045]
FIGS. 2-4B show different ways in which images can be oriented on print media. Various eye mark embodiments are shown thereon to illustrate some of the functions the various eye mark embodiments can provide. Although images are represented as pictures or boxes in this disclosure, the term “images” can represent any printed item on print media including, but not limited to, pictures, text documents, and combinations of images and text, among others. Additionally, those skilled in the art will appreciate from reading this disclosure that print media can be of various types and can take various forms. Suitable examples of the various types of media include, but are not limited to, paper, plastic, and cloth, among others. Further, an example of a suitable form of media includes, but is not limited to, one or more sheets of media ranging in size from individual sheets (or smaller) to continuous webs of media.

[0046]
FIG. 2 illustrates an arrangement of images and various embodiments of eye marks included on a print media 201. In the embodiment of FIG. 2, the images are laid out on the print media 201 in a single serial arrangement. As illustrated by the directional arrow in FIG. 2, the sheet of print media 201 is depicted as progressing from right to left typically through a processing device or processing system. Processing devices and/or systems can include multiple device components operable to perform one and/or many functions, e.g. a printing component, a cutting component, and/or a finishing component, among others. The invention is not limited to the direction of progression shown in the Figures. Further, as those skilled in the art will appreciate from reading this disclosure, the invention can be adapted to operate on any device or system wherein eye marks can be utilized.

[0047] The embodiment of FIG. 2 is intended to illustrate the use of various features of the present invention. In particular, in the embodiment shown in FIG. 2, an intersection of two print jobs, for example two customer image orders, on print media 201 is illustrated. A customer order is one or more images that are grouped together. Examples of customer orders include one or more prints from one or more rolls of film, one or more reprints, one or more prints from digitally stored media, and the like.

[0048] In the embodiment of FIG. 2, images 212-1 and 212-2 are part of a first customer order. In the embodiment of FIG. 2, a proof sheet 203 begins a new customer order, or group of images. A proof sheet, such as that shown at 203, typically has a thumbnail image 204 of each full sized image, such as image 202, to be printed in a customer order. A proof sheet typically also lays out the thumbnails 204 in the order that they are to be printed. The invention, however, is not so limited,

[0049] By way of example and not by way of limitation, image 202 is the first image of the second customer order and its thumbnail representation 204 is provided in the upper left hand corner of the proof sheet 203 to illustrate that it is the first image 202 in the customer order. The proof sheet 203 need not be the first item in a new order and that the order of the images 202 need not be as shown thereon.

[0050] Additionally, within a customer order or otherwise, images, e.g. 202, 203, 212-1, and 212-2 are to be eventually separated from each other. For this purpose, an eye mark 205 is provided in a blank space or open region 207, to indicate to a device that a cutting operation should occur. A cutting operation can separate two images in a space between the images so as not to cut the images themselves. This space is illustrated as the space between dotted-lines 206. The dotted-lines 206 are not necessarily present on the print media. In various embodiments, eye marks contain the information to identify a cut location (e.g. between dotted-lines 206) to a cutting component (not shown).

[0051] In various embodiments, as shown in the embodiment of FIG. 2, an eye mark is positioned between two adjacent images, e.g. 212-1 and 212-2, within the cutting space (e.g. space between the dotted-lines 206). In these embodiments, when the print media 201 is cut the region 207 including the eye mark 205 is removed from the print media 201 and adjacent images, e.g. 212-1 and 212-2, are separated. In various embodiments, an eye mark 205 is sized to fit within the region 207 to be removed by the cutting operation.

[0052] In various embodiments, an eye mark 209 can have a different pattern than eye mark 205. This difference, for example, can indicate that the adjacent images 212-2 and 203 are part of different sets of images. A set of images can be any set of one or more images, including, but not limited to customer orders, batches, spliced sheets, or other such groups of print media content. Thus, a detected change in an eye mark, according to various embodiments of the invention, can indicate the start of a new customer order and provide instructions to sort the next set of images into a separate stack or area. The invention, however, is not so limited.

[0053] Eyemarks such as 205 and 209 are detected by a sensor array including one or more sensors. The sensors can be designed to identify specific characteristics of the eyemarks or the sections that form them. For example, in FIG. 2, a sensor array includes several sensors 208-1, . . . , 208-N illustrated thereon. In this embodiment, the sensors 208-1, . . . , 208-N are stationary and the print media moves past such that each sensor monitors an area of the print media 201 that should contain a specific section of an eyemark 205/209. When an eyemark 205/209 passes by the sensors 208-1, . . . , 208-N, the eyemark 205/209 is identified and its encoded information is interpreted.

[0054] By way of example and not by way of limitation, in the embodiment of FIG. 2 the eye marks, such as eye mark 205 have three color sections 205-1, 205-2, and 205-N. The number of sections utilized is not limited to three and can include more or less sections according to the various embodiments. The colors, 205-1, 205-2, and 205-N, and their arrangement can provide instructions which can be operated on to direct or control a machine. That is, the colors, 205-1, 205-2, and 205-N, can contain instructions which can be detected and/or read according to one or more sets of computer executable instructions and operated on by one or more sets of computer executable instructions to indicate that the mark is an eye mark and to indicate where a print medium is to be cut.

[0055] The colors can be different from each other and can, therefore, create unique patterns to aid in distinguishing the eye mark from defects, debris, and image features, among others. Additionally, in various embodiments, primary or secondary colors are utilized in particular combinations and arrangements to help distinguish the marks from features within an image. Examples of primary colors and secondary colors in the image processing arts include, but are not limited to, cyan, magenta, yellow, red, green, blue, black, light cyan, and light magenta.

[0056] Operations that can be performed on each image can be different from one image to the next and the various embodiments of eye marks can contain the information to provide instructions to perform the different operations. Thus, the various eye mark embodiments, e.g. eye marks 205 and 209, can include information about the image or set of images and can include instructions on how the images and/or print media is to be handled with respect to a specific image or set of images.

[0057] In other embodiments of the invention, the sheet of material is wider and can accommodate several images across its width. FIGS. 3A and 3B illustrate two styles of formatting images in a matrix format for use on a wider sheet of media. Additionally, FIGS. 3A and 3B also include examples of other eye marks embodiments according to the teachings of the present invention.

[0058] In FIG. 3A, as in FIG. 2, the sheet of media 301 is again progressing from the right to the left. FIG. 3 also shows the end of a first order and the beginning of a second order. As in FIG. 2, the illustration in FIG. 3A has a first customer order including images 312-1, 312-2 and 312-3 and a second customer order including a proof sheet 303 and images 302-1 to 302-5.

[0059] The images in this embodiment are laid out such that as the sheet of material progresses to the left, a cut is intended to be made between the first vertical section of images (encompassing images 312-1 to 312-3) and the second vertical section of images (encompassing the proof sheet 303 and images 302-1 and 302-2) as generally indicated at 307. For this purpose, an eye mark 314 is provided to indicate to a device that a cutting operation should occur.

[0060] A cutting operation can separate the vertical sections of images in a space between the images so as not to cut the images themselves. This space 307 is illustrated as the space between dotted-lines 306. The dotted-lines 306 are provided to illustrate where a cutting component could cut the print media 301. These lines 306 are illustrative and therefore are not necessarily present on the print media.

[0061] In various embodiments, eye marks contain the information to identify a cut location (e.g. between dotted-lines 306) to a cutting component (not shown). In various embodiments, as shown in the embodiment of FIG. 3A, an eye mark is positioned between the two vertical sections of images, e.g. within the cutting space (e.g. space between the dotted-lines 306). In these embodiments, when the print media 301 is cut the region 307 including the eye mark 314 is removed from the print media 301 and the two vertical sections of images are separated. In various embodiments, an eye mark 314 is sized to fit within the region 307 to be removed by the cutting operation.

[0062] In addition to colored sections of the eye marks shown previously in FIG. 2, the eye marks 313, 314, 315, and 319 illustrated in FIG. 3A also include a trigger section 309 that indicates to the cutter where to center the cutting mechanism. In this embodiment, the sensor array 308 includes an additional sensor that is utilized to sense the trigger section 309.

[0063] In various embodiments, once the first vertical section of images is detached from the sheet of media 301, the first vertical section is cut again, this time between the bottom image 312-1 and the middle image 312-2. For this purpose, an eye mark 315 is provided to indicate to a device that a cutting operation should occur. A cutting operation can separate horizontal sections of images in a space between the images so as not to cut the images themselves. This space 317 is illustrated as the space between dotted-lines 316. The dotted-lines 316 are provided to illustrate where a cutting component could cut the print media 301. These lines 316 are illustrative and therefore are not necessarily present on the print media.

[0064] In various embodiments, eye marks 315 contain the information to identify a cut location (e.g. between dotted-lines 316) to a cutting component (not shown). In various embodiments, as shown in the embodiment of FIG. 3A, eye marks, e.g. 315 are positioned between the horizontal sections of images, e.g. within the cutting space (e.g. space 317 between the dotted-lines 316). In these embodiments, when the print media 301 is cut the region 317 including the eye mark 315 is removed from the print media 301 and horizontal sections of images are separated. In various embodiments, eye marks, e.g. 315, are sized to fit within the region 317 to be removed by the cutting operation. In this manner, images such as images 312-2 and 312-3 can be separated. By separating the images in this way, the order of the images is maintained throughout the process of separating them. In this embodiment, a second sensor array of one or more sensors 318 is illustrated. In this embodiment, these sensors 318 are arranged to read the sections of the eyemark 315 as it moves vertically by the sensors 318. However, the invention is not so limited.

[0065] In this embodiment, since image 312-3 is the end of the first order, the eye mark 314 can be encoded with information, such as identification of the next image as the start of the second order, and/or instructions on what operations to perform on the previous and next images. For example, the eye mark can indicate that the previous images should be stacked in one pile and that the new, a second customer order, should be stacked in a second pile or turned before stacking such that the first order and second order are collated. However, the invention is not so limited.

[0066]
FIG. 3B illustrates another style of arranging the images in a matrix format and includes a binary encoding section for an eye mark. This embodiment is configured such that serial strips, progressing from left to right, are to be separated from each other and then processed, for example, as shown and described in FIG. 2. However, the invention is not so limited. Accordingly, in this embodiment, areas between the serial rows of images, such as area 317 will be removed by a cutting component at dotted-lines 316. By cutting across these lines 316, three serial strips of images are formed.

[0067] In this embodiment, three rows of images are arranged horizontally in FIG. 3B with the images in each row being serially arranged from left to right and the sheet of material 301 progressing from right to left. For example, image 312-1 represents the end of a first customer order and proof sheet 303 illustrates the beginning of a second customer order with image 302-1 being the first image in the second customer order. The images 322-1 to 322-3 are part of a separate set of orders and are unrelated to the first and second orders described previously. Additionally, images 332-1 to 332-3 are unrelated to the images of 322-1 to 322-3 or the images of the first and second customer orders.

[0068] The eye mark illustrated in FIG. 3B includes a binary encoding section that allows for additional information to be encoded therein. The eye mark as shown, includes a three bit section 310 wherein the section is divided into three segments with each segment representing one bit of binary data. The combined three bit binary structure as shown in FIG. 3B can provide a decimal representation from 0-7. As those skilled in the art will appreciate from reading this disclosure, more than one binary section can be utilized in an eye mark according to the teachings of the present invention. Additionally, the array of one or more sensors 308 includes an additional sensor to detect the additional section 310.

[0069]
FIGS. 4A and 4B illustrate several other uses for eye marks and another type of eye mark configuration. In FIG. 4A, one sheet of print media has been spliced to another piece of print media at splice line 407. An eyemark 403 can be utilized to indicate that the cutting mechanism should cut the media at mark 403 and can indicate that the next segment of the print media contains a splice mark 407. Eye mark 404 can also be used to indicate when to cut the print media, but also that the splice has passed. At least one of these eye marks 403 and/or 404 can also include instructions on how to deal with the waste media containing the splice mark. Additionally, FIG. 4A shows an embodiment wherein eyemarks 415 having three sections and eyemarks having six sections 416 are utilized together on the media 401. Those skilled in the art will appreciate from this disclosure that any number of different eyemark formats can be utilized during processing of the media.

[0070] In FIG. 4B, a set of calibration information, in this case mark sensor calibration information 408, has been incorporated into print media. An eyemark 405 can be utilized to indicate that the cutting mechanism should cut the media at mark 405 and can indicate that the next segment of the print media contains calibration information 408. Eye mark 406 can also be used to indicate when to cut the print media, but also that the mark sensor calibration information 408 has passed. At least one of these eye marks 405 and/or 406 can also include instructions on how to deal with the waste media containing the calibration information.

[0071] Various embodiments for eye marks have been described above according to the teachings of the present invention. The various eye mark embodiments, described herein, are operable for use with image processing equipment. FIGS. 5A-9B illustrate various operating environments, such as image processing equipment, that can include and can implement various embodiments of the present invention. Various embodiments considered within the scope of the present invention are not limited to the operating environments shown in FIGS. 5A-9B.
