摘要： PURPOSE:To reproduce a simulated sound at plural listener positions with simple constitution and higher fidelity by correcting a simulated sound by one simulated sound generating means by an arrival delay time with the relative position from the sound source and a propagation attenuation data. CONSTITUTION:A sound generation simulating section 1 generates a sound from one sound source and stores it in a propagation delay memory 2 as a digital waveform. In this case, the sound pressure level written at first and the sound pressure level written in the next address are stored at a time difference by the sampling period. The simulated sound at the listener position is corrected by calculating a distance by a relative position calculation section 31 at first, calculating the delay time from the sound velocity and calculating the extraction address from the sampling period. The sound pressure level is read out of the relevant address of the memory 2, the attenuation level obtained from a propagation loss calculation section 5 is multiplied and an analog signal is reproduced from the data conversion section 61.

摘要： PURPOSE: To increase a processing speed by operating in parallel a system processor and an image processing processor.
CONSTITUTION: An arithmetic evaluating program of an image is executed by a system processor (SYSP) 1, and executes an access to an image memory (IMU) 4 and the start of an image processing processor (IP) 3 through an address processor (AP) 2. In such a case, the AP2 and the IP3 become a busy state until an operation is ended, and after the operation is ended, the busy state is released, and the arithmetic evaluating program inputs an image operation result and executes an evaluation processing. Also, while the SYSP1 is executing the arithmetic evaluating program, the image operation of the next object to be evaluated is executed by the IP3, it is operated in parallel to the AP2 and the idle time is curtailed, and the time of the whole image processing is shortened.

摘要： PROBLEM TO BE SOLVED: To obtain a highly accurate measuring method not affected by the state of water level by tracing the boundary line of a side segmented from a picture of an inclined water measuring plate or an inclined auxiliary plate and detecting the position of a water level from the disappearing position of the traced boundary or its bent point. SOLUTION: A system control part 1 controls a signal switch 6 and processes the measuring points of plural sites by only one water level measuring processing means. In addition, the control part 1 executes the general control of the whole system such as the control of an illuminating device 66 corresponding to the measured value of an illumination meter 68 arranged near the inclined water measuring plate 11, the control of an water level meansing processing body part 1 corresponding to the measured value of a visual field measuring device 50 and the display of a measured result on a display device 3. The plate 11 is arranged while inclined at a specified angle to the normal of the water level. Tracing processing is executed from the start point of calculation along the boundary of the side of the plate 11 or the inclined auxiliary plate which is segmented from an input picture and the disappearing position or bent point of the boundary is determined as water level position on the input picture.

摘要： PURPOSE: To make the toll collecting processing of a toll road into a non- stopping and unmanned system by storing the information of a vehicle obtained from a vehicle inspection sheet in a ROM and user individual information in an IC card loaded on an on-vehicle transponder. CONSTITUTION: The ROE 14 generated by a specific institute 38 is mounted by fixing on the transponder 10 loaded on the vehicle 9, and an insertion port for a freely inserted/extraced IC card 15 is provided on the transponder. The information of the vehicle obtained from the vehicle inspection sheet 17 is stored in the ROM 14, and the individual information 16 of a bank account number, etc., in the IC card 15. The presence/absence of a tow car is decided by measuring the presence/absence of the tow car by analyzing information with respect to the possibility of tow car out of the information described in the vehicle inspection sheet 17 and the images of cameras 19, 20 and 22 when the vehicle 9 passes a tollbooth. A charge is completely decided by performing charge calculation by using the information written on the ROM 14 out of the information described in the vehicle inspection sheet 17 and that with respect to the presence/absence of the tow car at the tollbooth.

摘要： PURPOSE: To eliminate the need to write image data, generated at a high frequency, directly in an external image storage device and to prolong the life by using the temporary image storage means. CONSTITUTION: The temporary image storage device 2 is installed between a camera and a final external image storage device 4. Plural frame memories are incorporated in the temporary image storage device 2 and one scene of an image can be stored in one memory. An image which is inputted from the camera at a high frequency is written cyclically in plural memories in the temporary image storage device 2. Another device decides whether or not each image scene needs to be stored in parallel, so the result is inputted and a mark is written in a memory management table 15, when an inputted image is written cyclically in a frame memory, this mark is checked to prevent the image from being written in a memory wherein an image which should be stored is present. When the number of images stored in the frame memories exceeds a certain value, they are transferred together to the external image storage device 4.

摘要： PURPOSE:To simulate a vague image generated in a translucent medium such as submarine with a simple method in three-dimensional computer graphic. CONSTITUTION:A background color is calculated by a medium color table 16, a transparent degree calculating part 13 calculates the transparent degree of an object color and the opaque degree of the background color based on a transparent degree definition table 14, and the object color corresponding to the transparent degree and the background color corresponding to the opaque degree are synthesized by color arithmetic parts 192, 193 and 194. Thus, the vague simulated image floated in the background color or embedded in the background color can be generated.
