1. Field
Embodiments of the present invention relate to bead and photo crafts. More particularly, embodiments of the present invention relate to a bead and photo craft kit and method for creating a bead array presenting a representation of an image, wherein the bead array is assembled from a collection of beads including a preselected number of bead colors and a preselected number of beads of each color.
2. Related Art
The use of beads in arts and crafts is well known. Beads are commonly used to create decorative crafts and artwork, including to create pictures using different beads for different details and colors of the picture.
In craft or art projects involving the use of beads to create pictures, the type and number of beads used is driven by the particular picture the user is attempting to create. If a user is attempting to create a picture with a substantial portion of the picture being blue, for example, creating the picture may require the use of a disproportionately large number of blue beads.
Because the type and number of beads used to create pictures are dependent upon the particular picture and vary from one project to another, efficiently providing a single bead craft kit for use with multiple bead art projects is difficult, as the craft kit will lack some beads of a particular color, will include too many beads of another color, or both.
Accordingly, there is a need for a bead craft which overcomes these limitations.
A method of generating a template for a craft kit in accordance with an embodiment of the invention comprises receiving a plurality of bead color values and a number associated with each bead color value, wherein each number corresponds to a maximum number of beads of that bead color value to be used in the template. The method further comprises receiving an image, selecting a pixel from the image, and identifying one of the plurality of bead color values that has an associated number greater than zero and is closest in color to a color of the selected pixel. The identified bead color value is assigned to the selected image pixel and the number associated with the identified bead color value is reduced by one. A template is generated with the identified bead color value indicated in a position on the template corresponding to a position of the pixel in the image.
A method of generating a template for a craft kit in accordance with another embodiment of the invention comprises establishing a plurality of bead color values and a number associated with each bead color value, wherein each number corresponds to a number of beads of the associated bead color value to be used with the template, receiving dimension information of a bead array, receiving an image, and adjusting (such as by scaling) the image so that each of a plurality of image pixels corresponds to a bead of the bead array.
The method further comprises, for each of a plurality of image pixels, identifying a subset of the bead color values that has associated numbers greater than zero, selecting an image pixel and identifying one of the plurality of bead color values from the subset that is closest in color to a color of the selected image pixel, assigning the identified bead color value to the selected image pixel, and reducing by one the number associated with the identified bead color value.
A template document is generated with each of the assigned bead color values indicated in a position in the template document corresponding to a position of the associated pixel in the image.
A method of enabling assembly of a bead craft in accordance with yet another embodiment of the invention comprises providing a kit, the kit including a collection of beads including beads of each of a plurality of colors with a pre-selected, fixed number of beads of each color, and a frame for assembling a bead array from the collection of beads. After providing the craft kit, the method further enables processing an image for use in generating a bead template document, wherein the image is provided by a craft kit user. A bead template document is then generated for enabling assembly of the bead array on a window pane of the frame, wherein the template document is generated by assigning a bead color to each of a plurality of bead positions on the template document to create a representation of the image using only beads from the collection of beads in the craft kit, and including a bead color indicator in each of the positions on the template document corresponding to the assigned bead color. The bead template document is then transferred to the user.
In certain embodiments of the invention, the frame has a transparent or translucent back plate for holding the template document between the front window and the back plate. The template is itself made of a transparent or translucent substrate and the colored beads in this embodiment are transparent or translucent. Accordingly, light from a window or lamp may pass through from the rear of the frame through the back plate, the template, the front window of the frame the beads.
In certain embodiments of the invention, a camera, such as a digital camera, is provided at a physical retail location, such as a retail store, booth at an arts and/or crafts festival, or cart or kiosk in a mall. A photograph is taken of the purchaser of a craft kit at the retail location and a template is generated and printed for the bead craft and provided to the purchaser at the retail location. Such embodiments of the invention may be self-service or implemented with the aid of a staff person at the retail location. The printed template may be placed in a box of the craft kit and/or placed directly in the frame, which may in turn be placed in the box.
In certain embodiments of the invention, the template is printed with visual representations of the locations at which to place the beads to serve as a guide for bead placement. In particular, the template may include circles each having a diameter corresponding to the diameter of the beads. A numerical indicator indicative of the bead color to locate in a particular circle may be printed within the circle. Additionally, each circle may be printed in a color corresponding to the bead color to be placed at the location of the circle. Additionally, the space outside each circle corresponding to the diameter of the circle may be colored or shaded including being colored or shaded with a color corresponding to the bead color to be placed at the location of the circle.
Additionally, in certain embodiments, statistical data of the colors in images, uploaded to a website of the invention, for which templates are generated is maintained, analyzed, and used to adjust bead count and/or bead colors in the bead craft kit of the present invention.

With reference now to
The bead container 36 may include a plurality of sections for holding beads 50 of two or more colors. For example, each section of the container 36 may hold beads of a particular color. The illustrated container 36 includes nine sections each operable to hold a plurality of beads. If one section is used to hold the bead identifier key 38, eight sections may be used to hold beads, such that the container 36 includes beads of eight different colors. Alternatively, the bead identifier key 38 may be configured for use outside of the container 36, such that all nine sections may be used to hold beads. In accordance with one exemplary embodiment of the invention, there are eight bead colors arranged in container sections with a middle or central section housing bead identifier key 38 which includes numerals corresponding to bead colors and arrows for designating each container section with a corresponding bead color. In one exemplary embodiment, bead container 36 is constructed of transparent, molded plastic.
The container 36 may include the same number of beads of each color, or may include a different number of beads of different colors. Furthermore, if there is a large number of beads of a particular color, those beads may be placed in two or more sections of the container to accommodate the larger number. While the present teachings contemplate virtually any number of container sections, any number of bead colors, and any number of beads of each color, an exemplary embodiment of the invention preferably includes between six and twelve bead colors, and more preferably between eight and ten bead colors, and includes between fifty and four hundred beads of each color. In accordance with one embodiment of the invention, there are a fewer number of beads of at least one of the lightest colored bead and the darkest colored bead in the kit 34.
For purposes of illustration, the bead container 36 in
A fill level or “height” of the beads 50 in each section of the container 36 is less than or equal to approximately 90% of a height of the section, less than or equal to approximately 75% of the height of the section, or less than or equal to approximately 60% of the height of the section. This helps to prevent beads 50 from falling out or otherwise escaping a particular section when the user places their fingers in the section to grasp or secure a bead.
The colors represented by the beads 50 may be chosen specifically to accommodate an intended image type. For example, if the craft kit 34 is sold specifically for use with portraits, the bead colors may be chosen to represent various hair colors and skin tones, including skin tones associated with persons of different ethnic backgrounds. If the craft kit 34 is sold specifically for use with landscape images, the bead colors may be chosen to best represent landscape colors, including colors associated with foliage and sky.
In particular, according to one aspect of the present invention, when the craft kit 34 is designed for facial portraits, hands, etcetera and skin and/or hair tones are used, the colors for the beads are chosen so as to be at least substantially evenly spaced across a color spectrum of common skin and hair colors ranging from light to dark.
In accordance with an aspect of the present invention, craft kit 34 includes a sufficient number of beads 50 of each bead color to create a portrait with any conventional hair and/or skin tones. For example, bead craft kit 34 would include a sufficient number of beads 50 of each color to create a meaningfully photorealistic beaded portrait of a light-skinned Caucasian with blonde hair. The same craft kit 34 would also include a sufficient number of beads 50 of each color to create a meaningfully photorealistic beaded portrait of a dark-skinned African-American with black hair. Similarly, the same craft kit 34 would have a sufficient number of beads 50 of each color to create a meaningfully photorealistic beaded portrait of an olive skinned brunette, persons of Asian or Hispanic descent, etcetera. In particular, rather than utilizing significantly more beads 50 than are needed to accommodate different hair and skin colors, the beaded portrait resulting from using the craft kit 34 may have somewhat of a Sepia appearance, thereby making it applicable to a wide-array of skin/hair tones. Additionally, the dithering techniques described herein—the mixing of beads of different colors in close proximity to each other—provides an illusion of a desired color or shading, thereby enabling use of an efficient number of beads of each color and preventing the need for significantly overstocking beads of each color in the craft kit to accommodate many different images.
In accordance with another aspect of the invention, bead colors are chosen based upon a selected image, such as a selected digital photograph. For example, a digital photograph of a flower, such as a red rose, is taken and analyzed for color. Given the particular shading, light conditions, etcetera, a typical red rose will actually have a plurality of red tones, ranging from light pink, to red, to deep red and even to a black or almost black appearance in the darkness of the folds between the petals of the flower. Additionally, a stem of the rose may have various shades of green. Accordingly, for example, as the result of a color analysis on a close-up of a rose for the purpose of selecting a color pallet for bead craft 34, a color palette for a red rose may be selected to have two shades of green, four shades of pink/red, a black and a brown, for example. Once these colors are selected, beads 50 can be made to correspond to the selected colors. While it will be understood that bead craft kit 34 may be used to make a wide variety of different beaded portraits, examples of specific beaded portraits for which bead craft kit 34 may be tailored include living items such as people, plants or animals or portions thereof (examples for illustrative purposes include a person's or peoples' face(s), hands, or feet, dogs, cats, birds, horses, butterflies, flowers, trees, etcetera) or formerly living items (such as dried flowers, leaves, fruits and vegetables, etcetera). A representation of a digital photograph used to create a template may be include in craft kit 34.
As used herein, a “bead” is a physical element used to create a representation of an image. The beads 50 may be substantially uniform in size and shape or may vary in size and/or shape, and may be spherical, partially spherical (such as, for example, cabochons), faceted or non-faceted, or may even present a cube or cone shape. The beads may be made of any suitable material, such as glass, plastic, or wood, and may have through-holes or be no-hole beads. The beads may be opaque or translucent and, in some instances, completely transparent. The beads may be textured or smooth and have a glossy, semi-glossy, or matte finish. In one embodiment, the beads 50 are each preferably between two and eight millimeters in diameter (or across, if not spherical), more preferably between three and six millimeters, and may particularly be about four or about five millimeters in diameter/across.
The frame 44 provides structure for the assembly of the bead array and displays the completed bead array. The frame 44 may be similar to a traditional picture frame and may include a rigid perimeter 52 made of wood, plastic or other rigid material, a sturdy back panel 54 including mounting or support elements 56, and a front-facing glass or plastic pane 58 that is transparent or partially transparent. The frame 44 may include a plurality of tabs 60 or other retaining means for retaining the back panel 54 in position proximate or against the pane 58. The retaining means 60 allows the back panel 54 to be removed and replaced to, for example, allow the user to place the template between the back panel 54 and the pane 58. In one embodiment, described further below, the back panel 54 is transparent, such as glass or clear plastic. In another embodiment, also described further below, the frame 44 does not have a back panel.
The frame 44 may be of virtually any size and shape, including conventional sizes such as eight inches by ten inches, five inches by seven inches, or three inches by five inches. In one exemplary embodiment, the frame 44 presents a rectangular shape, wherein the pane 58 has a length and a width each preferably within the range of from about 120 millimeters to about 220 millimeters, more preferably within the range of from about 160 millimeters to about 180 millimeters.
The container of adhesive 40 may be a bottle of conventional glue operable to secure the beads 50 to the pane 58. Preferably, the container of adhesive 40 is a container of high tack, transparent gel glue that applies clear and dries clear. Thus, the adhesive 40 is preferably applied in transparent, liquid form and is sufficiently strong to hold the beads 50 in place when dried. Other adhesive materials may be used without departing from the scope of the invention including, for example, adhesive tape.
The set of instructions 42 may be included in the kit 34 with directions for creating the template and assembling the bead array. As explained below in greater detail, the instructions 42 include directions for inserting the template into the frame 44 and creating the bead array by fixing the beads 50 to the pane 58 using the adhesive 40 according to a bead pattern presented on the template. The instructions 42 may be in the form of an instruction sheet or instruction manual. Alternatively, the set of instructions 42 may be accessible electronically via, for example, a webpage accessible via the Internet, an electronic communication, and so forth.
An exemplary method of assembling the craft kit 34 for distribution, sale or both is depicted in the flow diagram of
An exemplary method of using of the craft kit 34 to assemble a bead array is depicted in the flow diagram of
In one embodiment, the craft kit 34 and the software are configured specifically for use with a particular type of image, such as a portrait, wherein the beads 50 in the craft kit 34 include colors associated with portrait images, such as skin tone and hair color, and the software may include filters and functions associated with portrait processing, such as facial recognition and red eye removal. In other embodiments, the craft kit 34 and software may be configured specifically for use with other types of images, such as landscapes or sunsets, fruit, vegetables, animals, plants, and so forth. In yet another embodiment, the craft kit 34 is configured for general use wherein the bead colors do not correspond to any particular type of image.
Once the image is uploaded to the website the image is prepared, as depicted in block 82. For image preparation, the software may enable or perform manual or automated (or both) image manipulation and processing. By way of example, the software may enable the user to crop the image, may suggest a cropping action, or may automatically crop the image based on, for example, automated facial recognition. If the software enables manual cropping, the software may assist the user by providing visual feedback or guidance. The software may enable or perform virtually any image processing or manipulation function including, for example, brightness and contrast adjustment, as well as image stretching, skewing, and resizing to name a few. The software may further be configured to analyze the image to determine whether it is adequate for use with the craft kit 34. If the software is configured for use with portraits, for example, the software may determine the size of the face in the image, the color spectrum associated with the face or with the entire image, the level of detail present in the face or in the entire image, or any combination of these attributes, and suggest or require a new image if the uploaded image is not sufficient. By way of example, the software may suggest or require a new image with more facial detail, such as a new image with a “close up” of a subject's face. By further way of example, an auto-contrast function of the present invention may adjust the contrast of an uploaded image, before or after it is cropped or scaled, so that it has a selected number or percentage of one or more particular colors. In particular, the present invention may adjust the contrast of an uploaded image so that at least one, a selected number, or a selected percentage of each color in the bead color palette is used in the craft. In this way, if an image is too dark, it can be automatically lightened or vice versa. Additionally, if an uploaded image is too monochromatic, contrast adjustments can be made in an effort to distribute the color of the image across the palette. Additionally, it is an aspect of the invention to provide a recommendation to user that a particular image is too light, too dark, or too monochromatic to result in a desirable craft according to the present invention.
According to one aspect of the invention, the website of the present invention provides one or more slide interfaces that can be dragged with the aid of a user-input, such as a touch screen or computer mouse, that enables the brightness and/or contrast of the image to be adjusted. Such interfaces can be used in conjunction with the preview feature described below to enable the user to adjust an uploaded, input image to a desired appearance. Additionally, adjustments make an image appear too light or dark, such as determined by a number or percentage of pixels in particular categories, may produce an out of range message or other recommendations to the user. According to one aspect of the invention, the slide interface enables a scaled image to be adjusted only within the parameters of a bead count for each color of the scaled image or slightly beyond one or more bead counts up to a preprogrammed threshold, since the color dispersion techniques of the present invention, described below, can provide some accommodation for a bead count that has gone to zero.
Once the image is prepared, the software generates a template based on the image for use with the craft kit 34. The template generally provides a visual pattern for placing the beads 50, such that the resulting bead array presents an appearance similar to the image. The process of generating the template from the image is discussed below.
The software presents to the user a preview of the craft project, as depicted in block 84. The preview may include presenting an image of the template, a depiction of the anticipated finished bead project, or both. The software may generate a depiction of the anticipated finished bead project by, for example, building an image of a bead array corresponding to the bead pattern presented in the template and the colors of the beads 50 in the craft kit 34. The software may use actual images of the beads 50 to build the image, or may generate images of the beads 50 similar to the actual appearance of the beads. If the user is not satisfied with the preview, he or she may make changes by, for example, uploading a different image or further manipulating the image, such as by cropping the image differently. The preview(s) provided may be shown in a small area of the display screen or the present invention may provide an interface, such as a slide interface, to enable the user to adjust the viewing size of the preview(s). For example, by viewing a small displayed image of a preview the user will have a better representation of a view of the template or craft from a distance.
When the user is satisfied with the preview, he or she generates or requests a hard copy of the template by, for example, printing a copy of template as depicted in block 86. The user may print a copy of the template directly from the website or may request an electronic template document to be stored locally on an electronic device. The hard copy of the template includes indicia for bead placement on at least one side of the template. The user may print a copy of the template directly from the website, may download an electronic copy of the template document, or otherwise receive an electronic copy of the image document for storage, printing or both.
Once the user has a hard copy of the template, he or she may cut out or trim the template, as necessary, as depicted in block 88. The user places the template in the frame 44, as depicted in block 90, such that the indicia for bead placement is visible through the pane 58 and enables the user to place the beads 50 on the pane 58 following the visual bead array pattern presented in the template document. The hard copy of the template may be placed in the frame 44 in a conventional manner, for example, wherein the back panel 54 is removed from the frame 44, the template is placed against an inside surface of the pane 58, and the back panel 54 is replaced in the frame 44 against the template.
With the template placed in the frame 44, the user assembles the bead array by fixing the beads 50 to the pane 58 according to the pattern presented in the template, as depicted in block 92. As illustrated in
In accordance with an alternate embodiment of the present invention, the back panel 54 of frame 44 is transparent, such as glass or clear plastic. Additionally, in this embodiment, the template is preferably transparent or translucent and the indicia on the template representative of bead colors to locate in particular locations are preferably printed in light tones. In this embodiment, the beads 50 are preferably translucent, enabling light to pass through them. A finished bead craft of this embodiment may thus be placed in front of a window or lamp and light will pass through the transparent back panel and the template and the translucent beads. In a variation of this embodiment, a transparent or translucent template is adhered directly to the pane 58, such as the rear of the pane 58, of frame 44. Alternatively, a template, which does not need to be transparent or translucent, can be temporarily adhered, such as by taping, to the rear of pane 58 and then removed once all beads 50 are adhered in place on the front of the pane. It will be understood that, in alternate embodiments, the beads can be adhered to the rear of pane 58 and/or directly on top of and to the template. For example, in one exemplary variation of the present invention, the template may be placed upside down in a temporary fashion on the front of the window pane and the beads adhered to the rear of the window pane. When all beads are placed, the template can be removed. It should also be understood that frame 44 may have small hooks or loops to which ends of a chain or rope are fastened so that the finished bead craft may hang, from a hook, in front of a window or lamp.
An exemplary process for generating the template is illustrated by the flow diagram of
A count limit is assigned to each color of the color palette, as depicted in block 102. The count limit corresponds to the maximum number of beads of each color that could be used in the bead array and, correspondingly, that could be represented in the template. The count limit for each color may correspond precisely to the number of beads of the corresponding color present in the craft kit, or may be slightly less to accommodate lost or damaged beads. The count limit for each bead color may be preprogrammed into the software or may be provided as a software component or data file accessible by the software. The particular method or process of establishing the count limits may vary from one embodiment of the invention to another without departing from the scope of the invention.
A bead array size is established, as illustrated in block 104. The bead array size may include one or more dimensions of the bead array expressed in terms of, or corresponding to, a number of beads. If the bead array is rectangular in shape, for example, the bead array size may include a number of beads corresponding to a width of the array and a number of beads corresponding to a length of the array. Bead arrays of various shapes and sizes may be used without departing from the scope of the invention.
Both the color palette and the bead array size may be preprogrammed into the software or may be provided as a software component or data file accessible by the software. The particular methods or processes of establishing the color palette and/or bead array size may vary from one embodiment of the invention to another without departing from the scope of the invention.
The image is adjusted to match the dimensions of the bead array, as depicted in block 106. This step involves manipulating the image so that individual image picture elements or “pixels” correspond to particular beads or bead positions of the bead array. A large image may be reduced in size and stretched, for example, such that the number of pixels along a length of the image corresponds to the number of beads along a length of the bead array, and the number of pixels along a width of the image corresponds to the number of beads along a width of the bead array. Similarly, a small image may be enlarged to match the dimensions of the bead array.
It will be appreciated by those skilled in the art that adjusting the image such that each image pixel corresponds to a bead in the bead array is just one exemplary method of mapping the image to the bead array that may be used by the present invention. An alternative approach may be used, for example, that involves creating regions of the image corresponding to particular beads of the bead array, wherein each region is associated with a particular color and corresponds to a particular bead of the bead array or position on the bead array template.
The software scans the pixels of the adjusted image and stores one or more color values for each pixel, as depicted in block 108. The color values may be stored in a data structure within memory accessible by the software to facilitate, for example, using the color values in the subsequent process steps. Both the bead color values and the pixel color values may be numeric values defining a color, and may include a plurality of numeric values corresponding to components of the respective pixel or bead color. By way of example, each of the bead color values and the pixel color values may include numeric values corresponding to red, green and blue components of a respective composite color value.
For a selected pixel from the adjusted image, the software compares the color of the selected pixel to each color of the color palette that has a count limit greater than zero, as illustrated in block 108. This comparison may involve comparing numeric color values, such as Red (R), Green (G) and Blue (B) values associated with the selected pixel with numeric color values associated with each of the colors of the color palette and recording a difference between the two numeric values. The software identifies a bead color value from the color palette that is closest to the color of the selected image pixel and assigns the identified bead color value to the selected pixel, as illustrated in block 110.
The software stores the difference between the color of the selected image pixel and the identified bead color value from the color palette, as depicted in block 112. The difference may be stored as one or more numeric values corresponding to differences between numeric representations of the image pixel color and the selected palette color. By way of example, if the image pixel color and the selected palette color are each represented with numeric values corresponding to red, green and blue components thereof, the difference between the two colors may be expressed and stored as a numeric values representing the difference between the red, green and blue components of each number.
The color count corresponding to the selected bead color is reduced by one, indicating that one less bead of that color is available for use in the template, as depicted in block 114.
The software may disperse the stored difference in color to neighboring pixels for which the difference is not computed, as depicted in block 116. This step, which may be referenced as a dithering step, may be performed to offset the difference in color between the selected pixel and the identified bead color, thereby strategically placing bead colors in the bead array such that the representation of the image in the bead array more closely matches the color of the image. If the software selects a pixel in a corner of the image as the first pixel to be processed, for example, the software may determine that the closest color from the color palette is lighter than the color of the selected pixel and determine that the difference in color is represented by a number N. If neighboring pixels are similar in color to the selected pixel, it is likely that the same bead color will be identified for each of the neighboring pixels, wherein the identified bead color in each case is lighter than the corresponding image pixel color with a similar color difference value. This would result in the portion of the bead array corresponding to the selected pixel and neighboring pixels being lighter in color than the corresponding portion of the image. To prevent this from happening, the software may “disperse” the difference N to neighboring pixels by adjusting the target color of neighboring pixels to offset the difference associated with the selected pixel. In the example set forth above, this may involve assigning bead colors to those pixels that are darker than the respective pixel color by a difference of N, such that the combined effect of the lighter bead color corresponding to the selected pixel and the darker bead color corresponding to the neighboring pixels is a group of beads that appear to present a color similar to the corresponding group of pixels.
For example, each pixel in a scaled image utilized with the present invention may have a Red (R), a Green (G), and a Blue (B) component, as will be readily understood. Assume, for example, that a particular pixel is a bit darker than the nearest bead color in the bead color pallet. Although the particular pixel will be assigned the nearest bead color, the photorealistic bead craft of the present invention will actually be a bit lighter in this region than the actual image. Accordingly, the difference between the color of the pixel and the actual bead color may be stored and distributed to neighboring pixels. In particular, since it is now desired to offset the lightened appearance, the invention may attempt to darken the next neighboring pixel in an amount corresponding to the color difference stored for the preceding pixel. So, the RGB value of the next pixel is determined and then adjusted to be darker by an amount of the stored difference corresponding to the last pixel. This new, adjusted color is then compared with the bead colors in the bead palette and the pixel location is assigned a bead color that is closest to this adjusted color value. Again, for this pixel, a difference is calculated (whether lighter or darker) and dispersed to the next pixel. In a preferred embodiment, color differences between a particular pixel and an actual, selected closest bead color are dispersed to neighboring pixels in a weighted distribution. For example, 40% of the difference is distributed to the next pixel in a row, 30% of the color difference is distributed to the pixel under it, 15% of the difference is distributed to the lower left pixel, and 15% is distributed to the lower right pixel. Other distribution percentages can be employed and pixels on an edge may employ different rules or differences may roll over to the next row (or column, depending on implementation). Color difference and addition computations are well established art.
The software tracks which pixels have been processed and determines whether any pixels remain for processing, as depicted in block 118. If so, another pixel from the image is selected and processed. If all pixels have been processed, pixel processing is ended. Once pixel processing is complete, the software may present a preview of the template, the assembled bead array, or both, and may present the template for printing.
An exemplary website for enabling users to access the software is illustrated in
As described, craft kit 34 may be obtained in a retail store or via an online retailer and the user of the craft kit may upload an image to a website associated with the craft kit. In an alternate embodiment of the invention, a camera is located at a physical retail location (such as a physical retail store, a craft booth at an indoor or outdoor craft fair, craft show, or arts and crafts festival, or a cart or kiosk in or at a shopping mall) at which craft kit 34 may be purchased. Using the camera, a digital photograph of the user of the craft kit is taken. From the digital photograph, a template for making the beaded portrait according to the present invention is generated using software on a computer located at the physical retail store or by uploading the digital photograph to the website described herein. The generated template is printed and may be provided to the purchaser of the craft kit and even placed in the frame as a service to the purchaser. It will be understood that this embodiment may involve self-service, wherein the photograph may be taken by the purchaser and the purchaser using a computer to generate the template or, alternatively, a staff person working at the retail location may take the photograph and take steps to have the template generated by the software of the present invention.
The software may use statistical analysis to optimize the collection of beads that is included in the craft kit 34. By way of example, the software may track the number of beads of each color that are included in each template, the color of the image pixels, or both. If the software identifies a trend of certain bead colors being underutilized, the craft kit 34 may be adjusted to include fewer beads of those colors. Similarly, if the software identifies a trend of insufficient numbers of certain bead colors, the craft kit 34 may be adjusted to include more beads of those colors.
Furthermore, the craft kit 34 may be changed to include new bead colors if, for example, software determines that the new bead colors would more closely match the color of the pixels in the image. Although it will be appreciated that images uploaded to a website corresponding to the present invention may be stored on storage media, in accordance with one embodiment of the invention, only statistical data indicative of an image, and not the image itself, is stored (for example, the image itself can be deleted upon closure of a browsing session at the website).
Although the invention has been described with reference to the exemplary embodiments illustrated in the attached drawings, it is noted that equivalents may be employed and substitutions made herein without departing from the scope of the invention as recited in the claims. For example, the bead container 36 may take virtually any form, including, for example, the container illustrated in

Additionally, it will be understood that other embodiments may be made without departing from the invention. For example, a template generated using the software of the present invention could be printed on fabric, canvas or vinyl that could be used for clothing, handbags, apparel, etc. Additionally, rather than using beads to complete the craft, liquid that sets like a bead, such as colored glues, could be used, particularly for use in an embodiment of the invention on fabric. In an alternate embodiment, the craft could be completed using colored stamps, having tips that are preferably sized and shaped in the desired size, or using colored markers. In an alternate embodiment, the template could be generated on fabric for thread and needle craft to enable a crafter to stitch colored threads in corresponding locations on the template.
Having thus described various embodiments of the invention, what is claimed as new and desired to be protected by Letters Patent includes the following:
