    • A cellular phone which is easy to use featuring a sufficient degree of safety preventing unauthorized use by conducting a minimum degree of required authentication operation which is not perceived by the user. As the user holds the cellular phone 1 by hand, the control unit 12 issues an instruction to temperature obtaining units 15 to start detecting the temperature. The temperature obtaining units measure the temperature at regular intervals, and successively transfer the obtained temperature data to a temperature comparator unit 16. The temperature comparator unit judges whether the temperature data obtained by the temperature obtaining units are lying within a predetermined condition, and issues an instruction to biodata obtaining units 19 to obtain fingerprint data of the user depending upon the result of judgement. The biodata obtaining units obtain the fingerprint data of the user and transfer the obtained fingerprint data to a biodata authentication unit 20. The biodata authentication unit compares the obtained fingerprint data with the fingerprint data of the owner stored in a biodata storage unit 21, and judges whether the user is the proper user.
    • 容易使用的便携式电话具有足够的安全性,通过进行不被用户感知的最小程度的所需认证操作来防止未经授权的使用。 当用户手持手机1时,控制单元12向温度获取单元15发出指令以开始检测温度。 温度获取单元以规则的间隔测量温度,并将获得的温度数据连续地传送到温度比较器单元16.温度比较器单元判断由温度获取单元获得的温度数据是否在预定条件内,并发出 指示生物数据获取单元19根据判断结果获取用户的指纹数据。 生物数据获取单元获取用户的指纹数据并将获得的指纹数据传送到生物数据鉴定单元20.生物数据认证单元将获得的指纹数据与存储在生物数据存储单元21中的所有者的指纹数据进行比较,并且判断 用户是否是正确的用户。

    • 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。
