摘要： PROBLEM TO BE SOLVED: To provide a system and a method for coding an image of a document and finding out a position of a digital pen based upon the image. SOLUTION: A document page is encoded into codes associated with various positions of the document page. The codes are assembled into a codebook (301). Next, captured images are similarly encoded (302, 303) and searched against the codes in the codebook (304). One or a plurality of codes and associated positions are returned (305), thereby obtaining one or a plurality of possible positions for the captured images (306). COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide an input device and a method for the same for generating an electronic ink and/or other inputs.
SOLUTION: The input device can be used in combination of an arbitrary surface by using a movement sensing technology which has been improved to generate data so as to be used for the purposes related to and unrelated to the ink. Improved movement sensing is obtained by using one or more than one inertia sensors for detecting movement of the input device by measuring indicators such as changes in speed, acceleration, and electromagnetic field. The input device can include a memory for storing the motion data and a tranceiver for transmitting data for indicating the movement of the input device to the host computer. Also, it is possible to process the sensed motion data and to generate a picture for indicating a handwriting stroke by using a processor inside the input device. The input device can be formed in the shape of a pen and includes an ink cartridge. It is possible to make it easy to move the input device in a well-known way.

摘要： PROBLEM TO BE SOLVED: To provide a process and a device for analyzing a maze pattern image for extracting bits encoded into a maze pattern. SOLUTION: Grid lines of the maze pattern are determined, and the directions of effective pixels of a bar are estimated and grouped into clusters. A line is estimated for the effective pixels of the selected clusters. The grid lines of the other clusters are determined. The estimated lines are trimmed according to the inclination distribution analysis and grouped according to the distance analysis, and mostly fitting lines are selected from each group. An affine parameter is determined from the mostly fitting lines. A type of corner lacking in the maze pattern is determined and a right orientation of the maze pattern is obtained. Gray level values of the related maze patterns are processed and bits are extracted from the maze pattern image. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide an efficient technology for deciding a document part matching a captured image. SOLUTION: When a user creates a stroke in a document by means of a pen, an image of the document is captured by a camera mounted on the pen. Positions of some images are decided by analyzing a pattern on the document captured by the image, while positions of other images are decided by segmenting a sequence of the images into groups corresponding to the shape of the stroke. Then, using information about an already located image inside the segment, a position of an unlocated image is decided in the segment. Using rotation and a scale of the unlocated image, an unlocated image is warped. Then, pixel-by-pixel comparison is carried out between the warped unlocated image and a document search area. When the warped unlocated image is matched successfully, a transformation parameter of the image is refined further. COPYRIGHT: (C)2006,JPO&NCIPI
摘要翻译：要解决的问题：提供用于确定与拍摄图像匹配的文档部分的有效技术。
解决方案：当用户通过笔创建文档中的笔触时，文档的图像将由安装在笔上的相机捕获。通过分析由图像拍摄的文档上的图案来决定一些图像的位置，而通过将图像的序列分割成与笔划的形状相对应的组来确定其他图像的位置。然后，使用关于片段内已经定位的图像的信息，在片段中确定未定位图像的位置。使用旋转和未定位图像的刻度，未定位的图像会变形。然后，在翘曲的未定位图像和文档搜索区域之间进行逐像素比较。当翘曲的未定位图像成功匹配时，图像的变换参数进一步提高。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide camera-pen-tip mapping and calibration. SOLUTION: X-y positions of a digital pen's tip may be determined by using a calibration parameter to map the x-y positions of the respective centers of images captured by the pen's camera. The calibration parameter may be generated by iteratively calculating estimates of the calibration parameter. Calibration input data may be produced by a user placing the pen tip in a fixed location on a surface, which may be a positionally encoded medium, such as paper, and then rotating the pen and/or moving the opposite end of the pen in various directions to capture multiple images for use in generating the calibration parameter. A user may perform such a calibration procedure without the need for complicated calibration equipment typically used in connection with conventional calibration techniques.

摘要： PROBLEM TO BE SOLVED: To provide a process and an apparatus for determining the location of a captured array from a larger image. SOLUTION: A non-repeating sequence may be folded into a non-repeating array in which the array is unique for every neighboring window of a given size.

摘要： PROBLEM TO BE SOLVED: To provide a system and a method that determine a path of a pen tip as the pen tip is moved across a document. SOLUTION: The document is watermarked with a maze pattern from which encoded position information is determined. A sequence of images is captured by a camera that is located in a pen. The path of the pen tip is determined by decoding the associated maze pattern and by matching the captured images with document images. If the position coordinates of any frame that is associated with a stroke cannot be determined from m-array decoding, the frames are transformed and then matched with an area of a document image. Once the position coordinates of at least one frame is determined, the position coordinates of other frames can be determined by matching the frames in a neighboring area.

摘要： PROBLEM TO BE SOLVED: To provide an efficient technique for determining a portion of a document, corresponding to a captured image. SOLUTION: Areas of a document, in which the pattern is at least partially obscured, are identified. A reference pixel in the image is selected, and the offset between the pixel and the pattern is determined. A pixel-by-pixel comparison is then made of the image with the document, such that the reference pixel is compared only with the locations in the document that are both within the identified areas and have the determined offset from the pattern. The comparison with the highest correspondence between the image pixels and the electronic document then identifies the position of the reference pixel relative to the electronic document.
