    • There is disclosed an information reporting system comprising a communication host apparatus including a database storing a plurality of data sets each concerning predetermined position, and a host computer, and at least one portable terminal including a data processing unit for executing predetermined processing based upon data received from a communication unit via a communication networks, and a display unit displaying images obtained by the data processing. The portable terminal further includes a current position detecting unit for detecting its current position, and is adapted to transmit position information data indicative of the current position. The host computer is responsive to read out from the database one of the data sets concerning the position corresponding to the provided position information data and supplies the portable terminal with the data set.

    • An image processing apparatus includes an obtaining section, a detection section, a first identification section and a second identification section. The obtaining section obtains image data of a first picked-up image and a second picked-up image picked up by an image pickup section. The detection section detects a brightness change region where brightness changes at predetermined time intervals in the first picked-up image on the basis of the obtained image data of the first picked-up image. The first identification section performs straight line detection processing on the obtained image data of the second picked-up image to detect a straight line, so as to identify a candidate straight line in a corresponding region corresponding to the brightness change region. The second identification section identifies a quadrilateral region including the candidate straight line as an extraction candidate region in the second picked-up image.
    • 图像处理装置包括获取部,检测部,第一识别部和第二识别部。 获取部分获取由图像拾取部拾取的第一拍摄图像和第二拍摄图像的图像数据。 检测部根据所获得的第一拍摄图像的图像数据,检测第一拍摄图像中的亮度以规定的时间间隔变化的亮度变化区域。 第一识别部分对获得的第二拍摄图像的图像数据进行直线检测处理以检测直线,以便识别与亮度变化区域对应的对应区域中的候选直线。 第二识别部分识别包括候选直线的四边形区域作为第二拍摄图像中的提取候选区域。
