Disclosed are a solid-state imaging apparatus, a signal processing method of a solid-state imaging apparatus, and an electronic device, which are capable of correcting uneven sensitivities generated by multiple factors in a broad area and realizing the higher-precision image quality. A correction circuitweight a sensitivity Pi corresponding to a pixel signal of each pixel related to correction in a pixel unit PU that is the correction target and a sensitivity Pi corresponding to a pixel signal of each pixel related to correction in at least one same color pixel unit PU and adjacent to the pixel unit PU that is the correction target by a weighting coefficient Wi. Consequently, the correction coefficient &#x3bc; is calculated by dividing a sum of the weighted sensitivities by a total number n of pixels related to correction.

This invention constructs within the LAN a private area network (PAN) which is configured by terminal devices (personal computers and the like) of a specific group, is hardly influenced by the LAN traffic, and has high security. For this purpose, a PAN server which manages the communication route between specific terminals is installed within the LAN. The PAN server sets the communication route of each terminal device as label information, and causes switches and terminals to set pieces of label information generated for them. When the frame of data from a given port of each connection switch contains information representing PAN communication, the connection switch outputs the data to only a port specified by routing label information described in the frame.

Signals are evenly distributed and transmitted using a plurality of channels. Multicast and broadcast communications are efficiently made. Signals from each sub transmission paths are distributed onto a plurality of channels to send them via these channels. Furthermore, signals are inserted into the channels by finding empty packets from the channels, thus allowing input of signals to the channels that transfer various kinds of signals. Upon multicast or broadcast communications, an input signal is copied in correspondence with a plurality of channels.

A communication apparatus capable of transmitting a signal to a first channel group in a first transmission direction and a second channel group in a second transmission direction. When a signal received from the first channel group is outputted to the second channel group, a channel is selected from the second channel group.

In an optical concentrator a plurality of ports are provided for inputting and outputting first and second optical signals having different wavelength regions. An optical coupler is connected to each of the plurality of ports without being through remaining ones of the plurality of ports. The optical coupler transmits the second optical signal input from one of the plurality of ports to at least one of the remaining ports. A transmitter is provided to connect the plurality of ports in a loop form. The first optical signal input from each port is transmitted from the transmitter. Demultiplexers are arranged at each port for demultiplexing the first and second optical signals input from each port so as to guide the first optical signal to the transmitter and the second optical signal to the optical coupler.

Optical concentrator and optical communication network using the same

An optical communication network includes at least one optical transmission path, a plurality of terminals connected to the optical transmission path, a plurality of optical nodes for receiving and transmitting an optical signal between the optical transmission path and the terminals, and a controller for controlling the intensity of a signal output from each optical node so as equalize its intensity with the intensity of a signal input to each optical node from the optical transmission path. In this optical communication network, the loss of a signal's intensity is determined solely by the total extension length of the optical transmission path, so that the optical modes can be freely re-connected in the network.

Optical communication systems and optical nodes for use therein

When a communication network system is constructed using an optical fiber as a transmission path, a node which transmits a signal may receive its own transmission signal upon reflection of an optical signal on the transmission path. When access control to a network is performed by a CSMA/CD method, the reflection signal may be erroneously detected as a signal sent from another node, and a collision which has not actually occurred may be detected. In order to avoid this, a reflection signal component of the transmission signal must be removed from a reception signal. For this purpose, a time-inverted signal of the transmission signal, and the reception signal are modulated, and the modulated signals are then input to a convolver, thereby obtaining a convolution integral value between the two signals. Since the transmission signal component included in the reception signal can be detected from the obtained value, the detected transmission signal component is removed from the reception signal component, and a signal transmitted from another node can be extracted. In this manner, erroneous detection of a collision upon reflection of a signal transmitted from its own node can be prevented.

A liquid state resist is dropped to form a coating on a semiconductor substrate mounted on a rotary chuck disposed in a resist coating vessel in which a sealed solvent vapor atmosphere is created. An adjusting plate is provided in the coating vessel above the rotary chuck in a stationary or movable manner to weaken or substantially reduce a swirly flow of the solvent vapor which tends to occur in the coating vessel when the chuck is rotated. Thus a substrate coated with a resist film of uniform thickness is obtained.
