Abstract: It is an object to provide a technique capable of optimizing a caution degree which is a degree of caution to be exerted in a vehicle. A controller determines whether a mutual dangerous driving has been performed based on travel information of a plurality of vehicles acquired in an acquisition part, and obtaining a caution degree which is a degree of caution to be exerted in each of the plurality of vehicles based on a determination result. The controller performs control of correcting a caution degree of a first vehicle in the plurality of vehicles based on a caution degree of a second vehicle in the plurality of vehicles which has performed the mutual dangerous driving with the first vehicle.

Abstract: It is an object of the present invention to provide a driving support apparatus and a driving support method capable of performing an appropriate driving support. The driving support apparatus according to the present invention includes a processor to execute a program; and a memory to store the program which, when executed by the processor, performs processes of: acquiring information including an environmental information which is information indicating an environment of a road in a case where each of a plurality of vehicles travels, a travel information which is information regarding a traveling of each of the vehicles, and a vehicle information which is information regarding each of the vehicles, accumulating the acquired information, calculating a recommendation driving method based on the accumulated information and providing the vehicle which is capable of performing an automatic driving in the plurality of vehicles with a notice of the calculated recommendation driving method.

Abstract: It is an object of the present invention to provide a technique for selectively performing a desired function. A PC controls a display which is capable of displaying an image. When it is determined that a first prescribed operation which is prescribed in advance has been performed, a controller decides the first prescribed operation which is determined to have been performed, as a first operation used to perform a function of a predetermined application. The controller causes the display to display thereon a display icon which is capable of guiding the first prescribed operation to be performed.

Abstract: A cooling fan is rotated to cool an irradiation lamp and a read sensor during the reading operation and the standby period both. Although an airflow from the cooling fan is maximized during the reading operation, the airflow is reduced to the extent that a temperature rise originating from the self-generation of heat on the part of the read sensor in the standby condition is suppressed. Thus the temperature of the read sensor is kept constant and the characteristics of the read sensor are prevented from fluctuating. The airflow from the cooling fan can also be regulated by controlling the operating voltage to be applied to a motor for rotating the cooling fan and placing movable airflow regulating plates in the passage of the wind blown from the cooling fan. Thereby, accurate reading can be conducted in any color image reading apparatus since it is possible to minimize variation in the temperature of a read sensor for a certain time after the image reading operation is started.
