摘要： An X-ray imaging apparatus is configured to subtract a first X-ray image from a second X-ray image to generate a first subtraction image showing information on a blood vessel, calculate an amount of pixel shift between the first X-ray image and the third X-ray image, subtract the first X-ray image from the third X-ray image to generate a second subtraction image showing information on an insertion instrument, and combine the first subtraction image with the second subtraction image to generate a synthetic image by performing a pixel shift correction based on the amount of pixel shift.

摘要： Disclosed is a communication apparatus having a small-scale circuit used for modulation. A common transmission image rejection mixer (56) supplies transmission modulation frequencies to a plurality of quadrature modulators (23) (G, D, P, W). Accordingly, it is unnecessary to prepare the transmission image rejection mixer (56) for transmission signal types, makes it possible to prevent the circuit scale from increasing.

摘要： It is possible to achieve the miniaturization and the power saving of a hardware circuit as a multi-band radio signal transmitter/receiver, which can carry out a communication through a signal of a first communication method of transmitting and receiving a signal modulated by using information with regard only to a phase, for example, GSM/DCS, and a signal of a second communication method of transmitting and receiving a signal modulated by using an information of a phase and an amplitude, for example, UMTS (W-CDMA). A signal of PLL for a different reception channel is used as a local oscillation signal for a direct conversion reception, by using an image removing mixer or a reproduction dividing circuit, in each of GSM/DCS and UMTS modes, by switching a frequency of PLL in a transmitting IF signal in GSM/DCS/UMTS for each method, in order to generate a receiving signal used in GSM/DCS/UMTS.
