    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： According to the invention, on the basis of a deviation between an optical axis direction of a projection light and a normal line direction of a projection plane, image data can be changed and displayed so as to set off a distortion of a display image which occurs due to such a deviation. A quality of the display image is raised and a use efficiency is improved. In the invention, the image data is constructed by (m × n) pixels, the left upper position is set to an origin, an X axis is set to the lateral direction, and a Y axis is set to the vertical direction. A quadrangle ABCD corresponds to mapping data of an image stored in a memory. For example, in the case where the projection plane is inclined and the display image on the projection plane is enlarged as it approaches the right, the image is changed like a quadrangle ABEF. Namely, the image data is changed while increasing a reduction ratio in the vertical direction toward the right of the image. By projecting such changed image data onto the projection plane, the distortion occurring by the projection and the distortion on the mapping data are set off, so that an image without a distortion is displayed.

    摘要： A window system is constructed by a checking section to check an overlapping state of a plurality of windows displayed on a display, a forming section to form window graphs each showing the positional relation of each window when the windows are seen from another direction such as vertical or horizontal direction different from the overlapping direction and each corresponding to each window, a display such as a color CRT or LCD display to display the window graphs, a detector to detect an overlapped portion of the window graphs from the window graphs formed, and a changing section to change an attribute of the window graph to clarify the overlapped portion of the window graphs when such a portion is detected. By performing a selecting or operating instruction by a mouse cursor or the like to a desired window graph, the window corresponding to the instructed window graph can be selected or operated.

    摘要： The invention has means for judging the characteristics of a character from a feature amount of one inputted character, thereby allowing a suitable character recognizer to be adapted to the input character in accordance with the feature amount of the input character. According to the invention, since the means for judging the characteristics of a character in accordance with the feature amount of the inputted character, a size of input character is not limited. Each suitable recognizer is naturally selected in accordance with the feature amount of the inputted character. The input character can be more accurately recognized.

    摘要： When an image is drawn, a check is made to see if the image is overwritten onto an image which has already been inputted and displayed, thereby switching. For this purpose, a color of the image to be drawn and a color of the image which has already been inputted are compared and the image of the color of a higher priority is displayed. There is no need to reset a display priority of the image by a manual operation of the operator in consideration of the priority of the image. When the image is inputted, the priority of the image can be simultaneously decided. The image can be an image inputted by a hand-writing, an image inputted by a scanner, a character pattern which is generated from a character generator, and the like.
