Abstract: A pulse generation circuit (11) generates a pulse signal (S11) of “L” with a rise of a clock signal (CLOCK) as a trigger. A latch circuit (12) changes a latch signal (S12) fry “L” to “H” on the basis of the pulse signal (11) of “L”. Inverters (G10, G11) output a signal (XDEC) on the basis of the latch signal (S12). Even when the generation of the “L” pulse of the pulse signal (S11) is terminated and the pulse signal (S11) returns to “H”, the latch circuit (12) is in a data holding state to sustain the latch signal (S12) of “H” during a period while the signal READY takes “H”. With this constitution, it is possible to provide a semiconductor integrated circuit having a control unit which can output an operation control signal in synchronization with the clock signal without being constrained by the time length of “H” (“L”) period of the clock signal.

Abstract: An authentication device and an authentication method, a program storage medium and an information processing device improve the operability in the user authentication. By comparing the dial password entered by the rotation operation of the jog dial and the dial password registered in advance and conducting the user authentication, the user can enter the dial password intuitively and easily just by operating the jog dial and can make the user authentication be executed.

Abstract: There is provided an ultrasonic diagnostic apparatus in which ultrasonic waves are transmitted into the subject, the ultrasonic waves reflected within the subject are received to obtain received signals, and an image is displayed in accordance with the received signals thus obtained. The ultrasonic diagnostic apparatus has a CRT display according to the non-interlace scheme and a VTR according to the interface scheme. Image signals according to the non-interface scheme are converted into image signals according to the interlace scheme for recording onto the VTR. Image signals according to the non-interlace scheme are regenerated on the basis of only one of images on odd number lines and images of even number lines represented by the image signals according to the interlace scheme outputted from the VTR, so that an image is displayed in accordance with the image signals thus regenerated.

Abstract: An ultrasound imaging device having functions of storing data of at least one image in a memory and reading the data from the memory to show a freeze-frame on a display in response to a freeze instruction given by a user includes a discerning signal generation unit for generating a discerning signal which marks a change from one image frame to a next image frame in a video signal of ultrasound images, a discerning signal adding unit for marking a point of the change in the video signal by adding the discerning signal to the video signal, a control unit for stopping image data of the video signal from being stored in the memory after receiving the freeze instruction at a moment when the discerning signal is detected in the video signal, so that last two fields of the video signal stored in the memory and forming the freeze-frame are an even field and an odd field of the same frame.
