    摘要： In an image pickup apparatus for preventing linearity defect at the time of photographing in a high-sensitivity mode, when processing an image signal produced by a solid-state image pickup device under a predetermined condition, such as photographing in a super high-sensitivity mode, at a high temperature or with a long-time exposure, a signal processor increases a clamp level for clamping the image signal. A noise reducer then executes noise reduction for removing noise of random nature from the image signal before correcting the primary black level for the image signal, and thereafter the black level is corrected.

    摘要： An image combined high sensitivity image and low sensitivity image is provided with well-adjusted white balance and broad dynamic range. The image is obtained by multiplying the combined data by total gain that depends on scene. A white balance is adjusted with gain value calculated from of high output image data. Lv value representing luminance is calculated and compared with a threshold to decide whether or not the high sensitivity image and the low sensitivity image should be combined. First gamma correction unit performs gamma-correction for the image signal derived from the high sensitivity signal with first gamma character, second gamma correction unit performs gamma-correction for the image signal derived from the low sensitivity signal with second gamma character that is different from the first gamma character, and addition unit combines the image signal from the first gamma correction unit and the image signal from the second gamma correction unit.

    摘要： A radio communication device includes a reception unit for receiving a route request message from another radio communication device, a route control message processing unit for judging whether the received route request message is addressed to itself or not, a route request message management unit for deciding a delay amount for delaying response transmission or relay forwarding with regard to the route request message according to an operating state of the radio communication device when the route request message is not addressed to itself, and a delay processing unit which performs response transmission or relay forwarding to the route request message when the delay amount time has expired. Thus, a route selected giving preference to radio communication devices having a preferable operating state can be obtained.

    摘要： A router device includes a lower-layer information acquisition section for acquiring connection information of whether or not connected with a base station in an external network from a lower layer, and a route judgment section for transferring the received packet to the base station in the case of being connected with the base station and judging a transfer destination by looking up a routing table in the case of not being connected with the base station, when receiving a packet destined for a terminal in an external network from a radio terminal device in a same local network. Because the received packet is transferred to the base station during connection with the base station, the packet can be transferred to the external via the router intended by the terminal. Furthermore, the load in the local network can be reduced.

    摘要： A mobile communication method includes: a step for transmitting a binding update message for notification of a care-of-address of the network where the mobile network has gone, from a mobile router to a home agent, which can be used after the network has moved; and a step performed upon reception of the binding update message, for notification by the home agent of routing information concerning the route to the mobile network managed by the mobile router to the home network. Thus, the routing information from a mobile node is given to a gateway and the router on the home network without delay after movement, and it is possible to prevent loss of data sent to the mobile node belonging to the network to which the mobile network is connected after the movement.
