  • Publication number: 20100295976
    Abstract: The present invention relates to a solid-state imaging device, etc., which makes it possible to obtain an image with higher resolution by properly correcting pixel data even when any one of row selecting wirings is disconnected. A solid-state imaging device (1) comprises a photodetecting section (10), a signal reading-out section (20), a controlling section (30), and a correction processing section (40).

  • Publication number: 20100238948
    Abstract: A packet switching system capable of ensuring the sequence and continuity of packets and further compensating for delays in transmission is disclosed. Each of two redundant switch sections has a high-priority queue and a low-priority queue for each of output ports. A high-priority output selector selects one of two high-priority queues corresponding to respective ones of the two switch sections to store an output of the selected one into a high-priority output queue. A low-priority output selector selects one of two low-priority queues corresponding to respective ones of the two switch sections to store an output of the selected one into a low-priority output queue. The high-priority and low-priority output selectors are controlled depending on a system switching signal and a packet storing status of each of the high-priority and low-priority queues.

  • Publication number: 20090169126
    Abstract: An optical low pass filter (2) is formed, for example, by a birefringent plate so as to control the light beam separation width, thereby changing the cut-off frequency according to an imaging mode. The number of pixels of an imaging element (5) is set greater than the number of pixels corresponding to the dynamic image display resolution. In a still image capturing mode, the light beam separation width is set narrower so that the resolution of the imaging element (5) can be used as it is while suppressing generation of a false color to a certain degree. On the other hand, in a dynamic image capturing mode, the light beam separation width is set wider so that a high-frequency component corresponding to an unnecessary resolution component for an output image signal can be cut off and suppression of the false color can be performed strongly as compared to the still image capturing mode.

  • Patent number: 7227860
    Abstract: A packet switch includes (a) a plurality of inputs into each of which a packet is input, (b) a switch which receives the packet from the input and switches an output through which the packet is transmitted, and (c) a scheduler which controls the switch. The scheduler (103) includes (c1) a shuffler (201) which shuffles an order of precedence in a first request transmitted from the input to transfer the packet, (c2) a schedule algorithm (202) which determines the output, based on the first request having the order of precedence having been shuffled by the shuffler, and produces a second request to transfer a packet which second request is associated with the first request having the order of precedence having been shuffled by the shuffler, and (c3) a re-shuffler (203) which turns an order of precedence of the second request to be identical with the order of precedence in the first request as found before having been shuffled by the shuffler, and returns the thus turned order of precedence back to the input.
