    摘要： 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.

    摘要： 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. In this manner, once the original image data is stored, only difference data is sent at each subsequent transmission, thus reducing the amount of transmission data.

    摘要： 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.

    摘要： A coordinate input device interpolates sampling data, using less input data and simpler computing. The input data (coordinate information indicative of an input trace) are sampled both with a predetermined cycle (Tn), and at the end of a predetermined time interval after the sampling of the cycle Tn is complete. As a result of the two different samplings, not only the coordinate point determined by the sampling of cycle Tn, but also information indicative of a tangent vector at each coordinate point on the input trace are obtained. The coordinate point and the associated tangent vector information are thus output, so that a trace more faithful to the input trace is obtained using fewer coordinate points.
