摘要： PROBLEM TO BE SOLVED: To facilitate fitting and make cost lower in comparison to newly fitting the whole inter-vehicle distance control system to a vehicle previously mounted with a constant speed travel control unit by transmitting a false operation signal to the previously mounted constant speed travel control unit. SOLUTION: When an automatic constant speed travel setting switch 4a is operated and its signal is outputted to a microcomputer 1604 from an input port 1602, the same signal is transmitted to an automatic constant speed travel control device 2a from an output port 1606 so as to make constant speed travel control possible. Whether there is the danger of a collision is judged on the basis of inter-vehicle distance outputted from an inter-vehicle distance sensor input port 1608, relative speed data and vehicle speed data, and in the case of the automatic constant speed travel control device 2a being in operation, a signal for temporarily stopping constant speed travel control is transmitted to the automatic constant speed travel control device 2a from the output port 1606. In the case of no danger of a collision, a constant speed travel control restart signal is transmitted to the automatic constant speed travel control device 2a from the output port 1606.

摘要： PURPOSE:To provide an inexpensive and portable device which indicates a specific part of a picked-up image and converts the color of a desired area including the indicated part into an optional color that a user desires. CONSTITUTION:An image picked up by a CCD camera 2 is displayed on a monitor 18. The color conversion object part is specified with a sampling cursor by using a joy stick 32. A color sampling circuit 10 finds color data owned by the pixels constituting the sampling cursor at a specified position and an extracted color determination part determines extracted color data. A binarization circuit 22 finds extracted coordinate data indicating the object area of color conversion by setting pixels having the extracted color data among the pixels constituting the image to '1' and other pixels to '0'. The color information of the area determined with the extracted coordinate data is converted into substitute color data set by a substitute color determination part and displayed on the monitor 18.

CONSTITUTION:The electromagnetic waves 1-4 and 1-5 with ID numbers sent from a transmitter-receiver for walker are received by right and left reception antennas 1-1 and 1-2 and the distance and direction are calculated. The on- vehicle device estimates the degree of danger by processing the information such as the data, steering angle on the side of automobile, speed, accerelation, and brake. when a walker with high degree of danger exists, a danger signal is sent to the on-vehicle device and an electromagnetic wave 1-6 with the ID number of the portable transmitter-receiver for the walker is sent from a transmission part 1-3. The portable transmitter-receiver for the walker senses the only electromagnetic wave with ID number and outputs warning.
