Abstract: To provide a speaker device that can form a substantially uniform sound field over a range from a long distance to a short distance without significantly increasing a calculation load. A plurality of FIR filters 21 to 2n perform delay control of respective speakers so as to increase a delay time difference between adjacent speakers 51 to 5n in a line array speaker 5 toward one end of the line array speaker 5, and thereby over a wide range from a long distance to a short distance, a sound filed 12 is formed. Also, by adding a common shift delay time Dc to filter coefficients for the FIR filters 21 to 2n, the delay time difference between adjacent speakers 51 to 5n is made less than a sampling period of a sound signal to form a wide and uniform sound field 12.

Abstract: An intercom exchange is connected to multiple terminals, and includes multiple communication paths, a digital switch circuit for switching connections between the terminals and the communication paths, and a CPU that controls the DSPs and the switch circuit. The CPU performs control for preferentially allocating a communication path to the first terminal, and the allocated DSP determines whether a sound from the first terminal that has been received as input via the switch circuit is an abnormal sound. Upon determining that the sound is an abnormal sound, the allocated DSP notifies the CPU, and upon receiving the notification, the CPU determines an alert destination based on the notification and performs alert processing for sending an alert to the alert destination.

Abstract: To improve the data compression ratio in the data compression/decompression method utilizing the down-sampling process. Image data in a DS area division unit (130) is divided into a plenty of DS areas and DS areas which are not important are converted into contracted data of the block size by down-sampling in a down-sampling unit (131). A relocation unit (132) allocates two or more contracted data in one DS area, inserts file data into the other portion in the DS area, and removes the DS area where no contracted data is allocated, thereby reducing the entire image size. The image data thus contracted is inputted into a JPEG encoder (14) and subjected to a DCT process and a quantization process for each block. When performing restoration, decompression is performed by the JPEG decoder and the original location is restored. As for the contracted data, interpolation is performed to restore the image data.
