Abstract: An imaging control apparatus includes an HDR signal processor and a frame memory. The HDR signal processor obtains pixel data S1 and S2 obtained by imaging with a very short exposure time T1 and a short exposure time T2 earlier than obtaining pixel data S3 obtained by imaging with a normal exposure time T3, generates a luminance image data by separating illumination light component from the pixel data S1 and S2, the generation of the luminance image data starting when the pixel data S2 is obtained, and generates a gain for tone mapping from the luminance image data. On the other hand, the HDR signal processor generates an HDR image data from the pixel data S1 to S3, the generation of the HDR image starting when the pixel data S3 is obtained, and performs tone mapping by multiplying this image data by the gain.

Abstract: An OLT transmits and receives a CMTS/CM apparatus control signal through an apparatus physical management interface which is physically identical to or different from a main signal interface (NNI) and processes the CMTS apparatus control signal by itself. When connection of a new ONU is detected by an ONU apparatus control signal, an IP address is allocated by using the CM apparatus control signal in a manner similar to the CM. The CM apparatus control signal regarding the ONU is transmitted and received by using the IP address and a mutual conversion is performed between the CM apparatus control signal and the ONU apparatus control signal. The ONU processes the ONU apparatus control signal in a manner similar to the ONU based on an ordinary PON standard.

Abstract: Provided is an ONU that suppresses transmission of a useless multicast control message to a PON section and enables a communication bandwidth of the PON section to be effectively used. The ONU of the PON system has a multicast group management table that shows a correspondence between a multicast group identifier and an address of a user terminal participating in a multicast group. When the ONU receives a request message of participation in the multicast group from the user terminal, the ONU registers the correspondence between the multicast group identifier indicated by the received message and the user terminal address. A new received message is deleted without being sent to the OLT if another user terminal address is registered already, along with a correspondence with the same multicast group identifier, in the multicast group management table.
