Abstract: When a mobile station registered at a closed-type femtocell base station is in a connection state in a cell area covered by the femtocell base station, the transfer power of the femtocell base station for a cell identification signal is adjusted according to one scale estimating the receiving quality of the cell identification signal at the mobile station. When no mobile station is located in the cell area covered by the femtocell base station, the cell identification signal is sent with the minimum transmission power necessary for a mobile station to make a call in the cell area to reduce the power consumption of the femtocell base station and also to reduce interference with other macrocell base stations and other femtocell base stations.

Abstract: The present invention provides a technique to efficiently rearrange data in actual regions. A management system acquires load lumped region variation information (access distribution variation amount) indicative of a variation in the position of a virtual region in a virtual volume in a storage subsystem which region corresponds to a hot spot. Then, based on the load lumped region variation information, the management system determines a load position unvaried hour(s) indicative of a hour(s) in which the position of the virtual region corresponding to the hot spot is almost or perfectly unvaried (the hour(s) in which the position of the hot spot is stable). The management system then displays the load position unvaried hour(s) on a display device.

Abstract: Defective pixels are to be selected so as not to cause image degradation. A defective pixel correction unit 13 in an image processing apparatus 1 obtains an imaging signal a12 from an imaging sensor 16 via a gain adjustment unit 12, and calculates an absolute value for the pixel value difference between a pixel to be tested for a defect of the imaging sensor 16 and each of its surrounding pixels, respectively. Next, the defective pixel correction unit 13 compares the differential with a defective pixel determination threshold value and determines the pixel being tested as defective, if the differential is greater than the threshold value. It should be noted that the threshold value is changed according to the magnitude of an image transition, by detecting the image transition of a video signal a14 in an image transition detection unit 15.

Abstract: In a radio communication system where a base station provides blank time slots to avoid inter-cell interference, a decrease in throughput by an excess or shortage of blank time slots is prevented. This invention relates to a radio system that avoids interference in cooperation between base stations by providing blank time slots by a (first) base station. Other (second) base stations detect the number of served terminals affected by interference from the first base station that sets blank time slots, calculate required blank time slots so that the number of required blank time slots will increase with an increase in the number of terminals located in cell edges, and send a notification of the required blank time slots to the first base station. The first base station determines whether system throughput is anticipated to improve, based on the above notifications, and adjusts the length of blank time slots.
