Abstract: An authentication system includes: an imaging unit that is configure to switch between normal imaging and blur imaging that is imaging in a state of blurring with lower sharpness than that in the normal imaging; a target detection unit that detects an authentication target on the basis of a blurred image acquired by the blur imaging; a switching unit that switches the blur imaging to the normal imaging in a case where the authentication target is detected; and an authentication unit that performs authentication processing of authenticating the authentication targe on the basis of a normal image acquired by the normal imaging. According to such an authentication system, it is possible to perform the authentication processing in consideration of the privacy of the target.

Abstract: In a data/strobe encoding scheme circuit in which data and a strobe signal are transmitted through different lines, changes respectively in the data and the strobe signal are employed as clock signals for a latching operation, and the data is transmitted to a succeeding-stage circuit operating on a second clock signal. The circuit latches predetermined data by an FF circuit and passes a data pair including a signal indicating that the data has been latched and held therein as well as the latched data to the succeeding-stage circuit, activates, if assertion of a signal indicating reception of the data is received from the succeeding-stage circuit, again the FF circuit which has latched the data and has entered a stop state, and receives new data.
