Abstract: A camera apparatus includes a camera unit that is provided with a camera lens, a camera body that rotatably holds the camera unit, and a rotating mechanism that rotates the camera unit in response to an emergency signal so as to be switched from a first state where the camera lens is stored inside the camera body to a second state where the camera lens is exposed to an outside of the camera body.

Abstract: An extraction unit of fault assumption and a finish-point FF is provided, the fault assumption is selected from fault assumption information, and a logic trace is executed from the fault assumption toward an output side. A test result of a finish-point FF obtained as a result of the trace from the fault assumption is determined. The maximum value and the minimum value of the propagation route up to the finish-point FF are determined, and a delay margin is determined from the values. A delay range is determined by using the delay margin and the test result, and a fault candidate and a delay range of the delay fault are specified by the process of the determination of the fault candidate and the delay range.

Abstract: There is provided a technique for avoiding test-time IR drops which occur when the frequency that adjacent FFs in a scan chain have different logical values increases. An expected value derivation module derives the expected value of each FF by calculating probability propagation or performing logic simulation. A grouping module groups each FF subject to a test into a number of groups by referring to the obtained expected value. A scan chain configuration module pairs two groups whose logical-value-1 intake frequencies are opposite to each other, performs logic reversal on one group, and configures one scan chain.
