Patent number: 6346873Abstract: A parent node transmits a third specific message to child nodes as a broadcast message if a first specific message indicating the start of the child node collides with another message so that normal receiving cannot be performed. Then, the parent node sequentially transmits second specific messages to each child node and then receives responses to recognize the states of the children nodes. The parent node transmits a specific message indicating a realization of a sleeping state as a broadcast message to the children nodes, followed by transmitting a specific message when data to be transmitted from the child node has been generated. The parent node cancels the sleeping state when it receives the specific message.Type: GrantFiled: January 2, 1997Date of Patent: February 12, 2002Assignee: Canon Kabushiki KaishaInventors: Noriyuki Suzuki, Kazutoshi Shimada, Eisaku Tatsumi, Shinichi Sunakawa, Katsuhiko Nagasaki

Patent number: 6323839Abstract: A pointed-position detecting apparatus where image output unit visually displays an image, and image input unit inputs the displayed visible image. The input visible image is stored into memory as an original image. The visible image is partially changed by using a manipulation device such as a laser pointer or a pointing rod, and the visible image with the partially-changed area is inputted from the image input unit. Controller extract the changed image area from the input visible image, and detects a pointed position based on the changed image area. Thus, the phenomenon where a user's action with respect to a displayed image is reflected as a change in the image is utilized to detect coordinates and motion at the image area as the object of change.Type: GrantFiled: November 6, 1997Date of Patent: November 27, 2001Assignee: Canon Kabushiki KaishaInventors: Ryoji Fukuda, Kazutoshi Shimada, Eisaku Tatsumi, Shigeki Mori, Kazuhiro Matsubayashi, Shinichi Sunakawa, Takashi Harada, Katsuhiko Nagasaki

Patent number: 6249609Abstract: An image processing apparatus makes it possible to cut off a desired image with a high extraction rate irrespective of whether or not an inputted image has compression hysteresis. With the image processing method therefor, the inputted image data are at first divided into small blocks, and then, frequency transformation is executed. Further, small blocks are detected with respect to those containing character areas. Subsequently, detection is made as to whether or not any non-reversible compression is processed to the frequency transformed image data. In accordance with the result of such detection, data on a table are retrieved to obtain determination threshold values. On the basis of the determination threshold values thus retrieved, the small blocks containing characters are detected for separation.Type: GrantFiled: September 20, 1996Date of Patent: June 19, 2001Assignee: Canon Kabushiki KaishaInventors: Shinichi Sunakawa, Kazuhiro Matsubayashi

Patent number: 6031634Abstract: An image information transmitting/receiving apparatus for time and cost-saving repetitive transmission. In facsimile communication, image data where further information is added to previously-transmitted image data is often received. In the present apparatus, the original image data is stored, and only difference data from the original image data is transmitted, thus the whole image can be reproduced at the receiving side, using the received difference data. Upon transmitting the difference image information, identification information identifying the difference image information is added to the difference information, and the entire image data to be received by the receiving side is stored. Upon receiving the difference image information, the received difference information is combined with the stored image data, and an image is reproduced based on the combined image data. Further, the image data used for image reproduction is stored as original image data for the next transmission.Type: GrantFiled: June 14, 1995Date of Patent: February 29, 2000Assignee: Canon Kabushiki KaishaInventors: Kazutoshi Shimada, Eisaku Tatsumi, Shigeki Mori, Kazuhiro Matsubayashi, Shinichi Sunakawa, Takashi Harada, Katsuhiko Nagasaki, Ryoji Fukuda

Patent number: 5982928Abstract: A system consisting of a plurality of terminals connected through communication is sometimes used to acquire information input from the terminals to a host terminal and edit/arrange the information in the host terminal when information is exchanged by inputting handwritten characters from the terminals. In this case, the host terminal must recognize the handwritten characters and thereafter process the characters to arrange the handwritten character information. Each terminal can perform character recognition by a unique character recognizing method. The terminals also individually prepare dictionaries for recognition. The host terminal returns the acquired handwritten character information to the terminals and causes the terminals to perform character recognition. Alternatively, the host terminal concentratively manages the character recognizing methods and dictionaries of all the terminals and performs character recognition.Type: GrantFiled: June 19, 1995Date of Patent: November 9, 1999Assignee: Canon Kabushiki KaishaInventors: Kazutoshi Shimada, Eisaku Tatsumi, Shigeki Mori, Kasuhiro Matsubayashi, Shinichi Sunakawa, Takashi Harada, Katsuhiko Nagasaki, Ryoji Fukuda

Patent number: 5974191Abstract: An image containing characters and lines, which is inputted by a scanner or the like, is binarized and stored in a memory. A thickening process is repeatedly applied on groups of significant bits stored in the memory, until a predetermined condition is fulfilled. After this process, the thickened image is thinned at least a greater number of times than the number of times the thickening process is repeated in order to eliminate lines. As a result, characters are determined to exist at areas where groups composed of remaining significant dots exist, then characters are separated from the input image based on the areas of groups composed of the remaining significant dots.Type: GrantFiled: October 14, 1997Date of Patent: October 26, 1999Assignee: Canon Kabushiki KaishaInventors: Takashi Harada, Kazutoshi Shimada, Eisaku Tatsumi, Shigeki Mori, Kazuhiro Matsubayashi, Shinichi Sunakawa, Katsuhiko Nagasaki
