摘要： The present invention is to provide a method for identifying an optical line easily and accurately regardless of the optical line length. A plurality of reflecting parts is placed on the optical line, and a combination of relative positions of the reflecting parts is changed for every optical line to form an identification code, and the relative positions of the reflecting parts are detected based on reflected lights when a detecting light is inputted to the optical line, so that the optical line is identified based on a result. Concretely, when the detecting light is inputted to one end of the optical line, the light is reflected at the plurality of the reflecting parts which form the identification code and comes back the input end. A combination of the relative positions etc. of the reflecting parts is changed for every optical line. To detect the relative positions of the reflecting parts which form the identification code, either the optical path difference of the reflected lights from the reflecting parts is measured or the time difference between the reflected lights come back from the reflecting parts is measured. Then, based on the result, the optical line can be identified.

摘要： A telop character extraction apparatus generates a gray-scale image from a telop region image, and generates an edge region image where an edge is extracted from within the gray-scale image. The apparatus uses the edge region image as a mask image, and creates a luminance histogram of pixels of the gray-scale image. The apparatus divides a luminance of the luminance histogram into luminance classes. The apparatus generates binary images where pixels of luminances belonging to the individual classes are collected for the respective luminance classes, and selects the binary image of the class of maximum area, as a telop character candidate image. The apparatus decides on a character color used in the telop region image, in correspondence with the telop character candidate image, and extracts character pixels corresponding to the character color, from within the telop character candidate image, thereby to eliminate noise pixels and to generate telop character image.

摘要： A pointing information extraction unit extracts pointing information indicating a pointing position and a pointing time on a slide from a slide file used in a lecture and a video file of a lecture video using a pointing device. A word information generation unit analyzes a text sentence extracted from the slide file to generate a word information file indicating a word and a position thereof. A word pointing information generation unit estimates a word closest to the pointing position on the slide to generate a word pointing information file with the pointing time assigned. A fill-in-the-blank word extraction unit extracts a word having a pointing time equal to or longer than a predetermined time from the word pointing information as a fill-in-the-blank word file. A fill-in-the-blank test question is generated by setting the fill-in-the-blank word of the slide information as a blank region.
