Abstract: A generator generates a visible light video signal by receiving visible light and generating an invisible light video signal by receiving invisible light. A synthesizer synthesizes the visible light video signal and the invisible light video signal in such a manner that a synthesis ratio can be changed. An adjuster receives parameters relating to image synthesis inputted by an operator from outside and adjusts the synthesis ratio based on the received parameters. A display unit generates a synthetic image from a synthetic video signal and displays the synthetic image. Then, the parameters inputted to the adjuster by the operator are received and the synthesis ratio is changed by the adjuster based on the received parameters while the synthetic image is being displayed by the display unit.

Therefore, the operations of data output terminals are synchronized with the operation of the logic circuit (100) while keeping the phase relationship between an external output clock and external output data.

Abstract: In a filter correction circuit for a camera system according to the present invention, a sample area information detector detects frequency band and fluctuation level of a video signal by a unit of sample area where a screen is divided into a plurality of areas. A filter area information detector detects the frequency band and fluctuation level of the video signal by a unit of filter area that is a subject of one-time filter processing in the single screen. A filter condition switching judgment device generates a selection control signal based on the result detected by the sample area information detector. A selector selects a filter coefficient to be applied based on the selection control signal. A filter processor fetches the filter coefficient selected by the selector, from a filter coefficient register, and applies it to the pixel unit or smallest pixel group unit that corresponds to the filter coefficient.

Abstract: Improvement is obtained in quality of transmitting by extraction of the accurate transfer data from the Symbol data stream includes Guard Interval and transfer data. The first aspect of the present invention is expansion of the size of the memory means for inputting to be able to store N+n samples (N means the size of symbol data, n is smaller than GI) using means to input the discrete input data sampled at a constant period, and fetch N samples of data from the optimum position. In the second aspect, the size of memory block for inputting stores N samples (N is power of 2, and N means the size of symbol data) as not changing their size. For inputting, at least 2 memory blocks are allocated with the function to independently control the riming to initiate fetching the input data to the each block. Therefore the data at the optimum position can be selected at the operation.

A hand-off order message is transferred from the present base station toward the mobile station. The control office is adapted to control the adjacent base station to transmit the hand-off order message if it fails to receive a hand-off confirmation from the mobile station.
