Title: Multicast shortcut routing method
Inventor: DUMORTIER PHILIP VINCENT
IPC: H04L45/16
Filed: 1999-12-16
Abstract: PROBLEM TO BE SOLVED: To evade the unnecessary use of network resources by an unrelated receiving host by not setting up a shortcut path unnecessary by postponing setting up a shortcut path until a prune message possibly arrives. SOLUTION: A transmitting host SH broadcasts an Internet protocol(IP) packet flow to receiving hosts RH1 to RH6 through switching routers SR1 to SR11. To indicate that the RH1 to RH6 do not desire to receive the IP packet flow, the prune message is sent to the switching routers SR1 to SR11 in the direction of the transmitting host SH and the reception is postponed until the prune message possibly arrives, so that a shortcut path is not set up unnecessarily. Consequently, an unrelated receiving host sends the prune message to indicate that and network resources are not used unnecessarily.

Title: Image pickup device and computer readable storage medium
Inventor: IKEDA EIICHIRO
IPC: H04N9/07
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To eliminate the occurrence of lateral stripes based on arrangement of color filters in an image photographed by an image pickup element provided with a color filter. SOLUTION: An output signal of an image pickup element is corrected by using a same color correction coefficient that makes an output value of an optional color element from the image pickup element having a color filter 116 equivalent to an output value of other color element in the same color as that of the color element. For example, with respect to a color Ma, there are a color Ma between colors Cy and an Ma between colors Ye, and since output values of the two colors Ma differ, lateral stripes are produced. Then a mean value of the two Ma colors is obtained and a ratio of the mean value to each Ma is obtained respectively to obtain the same color correction coefficient.
