    摘要: A camera having a camera-shake detecting device is arranged to make a display indicating that a shake of the camera is undetectable only in cases where the camera shake is consecutively found to be undetectable for a given number of times while a camera-shake detecting action is repeatedly performed. This arrangement effectively prevents the display from being flickered by alternate displays of an undetectable state and a detectable state if the undetectable state is displayed every time the undetectable state of camera shake takes place.

    摘要: A digital signature generating apparatus generates a digital signature of digital data. The digital signature generating apparatus includes a receiving unit, the secret key changing unit and a digital signature generating unit. The receiving unit receives one of a first command and a second command. The first command includes information indicating one of a plurality of secret keys, and the plurality of secret keys are included in the digital signature generating apparatus. The secret key changing unit changes a secret key used by the digital signature generating apparatus to a secret key specified by the first command, if the first command is received by the receiving unit. The digital signature generating unit generates the digital signature of the digital data from a hash value extracted from the second command, if the second command is received by the receiving unit.
