Abstract: A contact sensor capable of inputting a character by tracing a character with user's finger is arranged in a region of a ten-key unit of a mobile telephone. When registering a password to release a key lock, a user traces a shape of a line, a character, a number, or other symbol on the contact sensor with his/her finger so that the shape is inputted and stored in a memory, thereby completing registration of a password. When releasing the key lock, the user traces the registered shape on the contact sensor with his/her finger so that the key lock is released. The input is easy. Even if the password input operation is observed by a third person, the password will not be easily known to the third person.

Abstract: A portable telephone is provided with a camera module (13) for outputting a captured image as image information, a memory (105) for storing the image information, a face registration unit (504) for holding information relating to a face image, a face extraction unit (501), a face parameter extraction unit (502), and a matching determination unit (505) which serve as the configuration for detecting the face image held in the face registration unit (504) from the captured image, and an image-capturing control unit (506) for executing control processing for image capturing. The image-capturing control unit (506) stores the image information in the memory (105) on the basis of the fact that after the face image held in the face registration unit (504) is detected, the face image becomes undetected, and the face image is then detected again.

Abstract: An input device capable of avoiding simple input of the correct password and a portable telephone device are provided. A contact sensor (56) enabling input of a line by moving a finger of the user on an area where numeric keys (48) of a portable telephone (10) are arranged is provided in the area. When password information for canceling key-lock is registered, the user moves a finger of the user on the contact sensor (56) to input a linear shape. The data on the key with which the user first comes to contact when the user tries to input the line and the data on the key from which the user separates the user's finger last are registered for each place, thus completing the registration of the password. When the user wants to cancel the key-lock, the user operates the contact sensor similarly to the registered content. Then the key-lock is canceled.
