The present technology relates to an information processing device, an imaging device, an information processing method, and a program capable of generating an appropriate digital signal having high quantization precision from a digital signal having low quantization precision. High-precision component information is extracted from an unprocessed signal that is a digital signal not subjected to predetermined signal processing and having first quantization precision, and a reproduction signal in which quantization precision of a processed signal obtained by performing the predetermined signal processing on the unprocessed signal is reproduced to the first quantization precision on the basis of the high-precision component information is generated. The present technology is applicable to, for example, an imaging device.

A joint-optimization method addresses the generalized routing and wavelength assignment problem with variable number of combined 1+1 dedicated and shared connections. The inventive method enables a solution in time that is polynomial of the input size. Thus, the time complexity of the joint-optimization method is significantly less than that of existing methods.

The inventive 2-step-optimization procedure that addresses the generalized routing and wavelength assignment problem with variable number of combined 1+1 dedicated and shared connections for the first time. The proposed procedure results a solution in time that is polynomial of the input size. Thus, the time complexity of the 2-step-optimization procedure is significantly less than that of existing methods.

Upon opening traffic of a communication line passing a plurality of cross-connect devices (nodes), the cross-connect control information of each node input by the operator is input to be transmitted to each node via the network control device. In this case, redundancy of the network control information is avoided to reduce the control information amount. Since the sender and destination path names and the sender and destination leading time slot numbers between mutually opposing nodes are respectively the same, by a man-machine interface device, there are input the same information to respectively add the path name and the leading time slot number before and after respective node numbers. The cross-connection control information of all of nodes are transmitted to the network control device with a single network control information. In the network control device, the cross-connect control information per node is separated from the single network control information for re-construction.
