Image processing device, image processing method and graphic editing method

The invention relates to an image processing device and method for combining a background image and micro image information for optical recognition, and a graphic editing method for processing micro image information.

In the production of general audiobooks, information such as sounds, images, or other special effects that are required to be presented is usually represented by a micro graphical indicator formed by a coded design, and is arranged by image indicators. The optical identification (OID) code pattern can be embedded in the book draft with the text and image content edited when the book is printed. Therefore, when a reader reads an audio e-book, a specific hardware device such as an optical pen can read an image index corresponding to a character or an image, and present a sound, image, or the like corresponding to the text or the image content. Special effect.

1 is a schematic diagram showing a graphical indicator 102 formed on an object surface 100. As shown in FIG. 1, the image index 102 is composed of a plurality of graphic micro-units. Since the micro image unit is relatively small, it is easily visually ignored or interpreted by the human eye. The pattern formed by the arrangement of the micro image units is generally also referred to as a bottom code pattern. The bottom code pattern and main information 104 (the character pattern "APPLE" of FIG. 1) can be formed together on the object surface 100 such as paper by, for example, printing. The image indicator 102 is a mapping of the indicator data and does not affect the reception of the primary information 104 by the human eye. 2 is a schematic diagram showing an electronic system 110 having an optical device 112, a processing device 114, and an output device 116 for performing an image recognition program to read the image indicator 102. The optical device 112, the processing device 114, and the output device 116 are connected to each other by wire or wirelessly. The optical device 112 reads the surface of the object to obtain an enlarged image, and then the processing device 114 self-magnifies The image index 102 is taken out from the image and converted into digital data, and additional information corresponding to the digital data is obtained. Finally, the output device 116 receives this additional information and outputs this additional information in a predetermined form. Therefore, by the design of the image index 102, more common information such as sounds can be carried on the surface of a common object such as a book page.

For example, in an environment of an audio e-book, if an image index 102 is correspondingly distributed at a pattern or a character position appearing on a book page, the optical device 112 can recognize the micro image when the surface of the object is read. The digital information represented by the cell arrangement, such as the audio that can emit a specific sound. Therefore, in order to distribute a large number of patterns, characters or words on a page, it is necessary to first find the micro image unit corresponding to each pattern, character, or word, and then map the pattern, the text, and the corresponding micro The image unit is printed on the corresponding location on the page. For example, the current practice is to use two-stage processing flow of two different image editing softwares respectively, one of which is to find the micro image unit corresponding to each pattern, and then use a software to edit the bottom code corresponding to the entire page pattern. Pattern; another stage is to obtain the code value of the character or word on the corresponding page and the micro image unit corresponding to the code value by another editing software, and finally all the micro images corresponding to the pattern, the text and the two. The unit is printed on the corresponding position of the page, so the entire process of editing and printing the text is quite complicated and time consuming. Therefore, how to propose an integrated design to simplify the process of attaching image indicators to the surface of an object is an important issue.

The unidirectional exchange code (UIC code) encodes 65,536 code positions to which a word plane belongs, which can correspond to various characters, words, and notes (in Chinese, for example, each broken word), and a custom symbol. Or user-defined information content such as an audio file corresponding to a trigger event or a digital file of other special effects on the e-book page. Therefore, corresponding to each character, word, note, custom symbol, or the bottom code pattern of the user-defined information content, The association with the universally commutated coded location can be established in accordance with the design of the present invention. As shown in FIG. 10, each of the bottom code patterns 40 embedded in the background image 30 corresponds to one of 65,536 coding positions to which a plane in the universal code exchange (UIC code) coding structure belongs. For example, the bottom code pattern representing the Latin alphabet A corresponds to the "1" code position of the universal exchange code (UIC code), and the bottom code pattern representing the Latin letter B corresponds to the "2" code of the universal exchange code (UIC code). The position, representing the bottom code pattern of the Latin letter C corresponds to the "3" code position of the universal exchange code (UIC code) and the like. Therefore, with the design of the present invention, the correspondence between the coding position and the bottom code patterns of various types is established by using the universal code exchange code (UIC code) coding structure, so that the overall application is more systematic and more efficient. Furthermore, the bottom code pattern 40 in the composite image 50 may also correspond to other similar encoding structures such as a Unicode encoding structure. For example, the bottom code pattern representing the Latin alphabet A corresponds to "0041" of the Unicode code. "Code position, the bottom code pattern representing the Latin letter B corresponds to the "0042" code position of the universal code (Uni code), and the bottom code pattern representing the Latin letter C corresponds to the "0043" code of the universal code (Uni code). Location and more.

Therefore, a flowchart of FIG. 11 shows a method for editing a bottom pattern pattern according to the present invention, the method comprising the following steps:

S10: Start.

S12: providing a background image on a page to be edited, a user-defined information content (such as a digital file corresponding to an event file or other special effects), and text information (such as characters, words, notes, or self) Order symbols, etc.).

S14: Identifying a coding position corresponding to each received text information by using a 10,000 code encoding structure, and coding the user-defined information content into the UIC code coding structure reserved. The user defines the coding location by himself. Since each user defines the information and the text information, there is a corresponding bottom code pattern and a bottom code index value, so that the coding position of the universal exchange code (UIC code) coding structure and the respective bottom code patterns and bottom code index values are established. Association Sex.

S16: Output a base code pattern or a bottom code index value and a background image that are associated with a code structure of a universal exchange code (UIC code). The output file can be, for example, a UIC code text file or a UIC code binary file.

S18: End.

Although the above-mentioned bottom code pattern editing method is to process the background image, the user-defined information content, and the text information together, the method is only an embodiment and is not limited. For example, the encoding position corresponding to each received text information may be identified by using a UIC code encoding structure, and the user-defined information content may be programmed into the universal exchange code (UIC code). After the user of the coding structure reserves the code position, the bottom code index value corresponding to the user-defined information and text information is output as a UIC code text file, as for the background image. The combined action can be performed at other stages without the need to process the information content and text information defined by the user.

Furthermore, the present invention is not limited to the use of a universally commutated code (UIC code) coding structure to establish association, and may also use other coding structures, such as a Unicode coding structure, to identify the coding location corresponding to each received text information. And the user-defined information content is programmed into the user-defined coding location reserved by the Unicode code structure. At this time, the output file can be a Unicode text file or a Unicode binary file.
