An image display device corrects image data, which are used for displaying an image, using a gray scale value assigned to each pixel and also controls the amount of source light emitted from a light source. The image display device includes a source light amount control device and an image correction device. The source light amount control device determines the amount of source light and then controls the amount of source light. The image correction device corrects a signal used for changing saturations of the image data so as to reduce a change in the saturations due to a change in the amount of source light, the change in the amount of source light being performed by the light source amount control device.

摘要:
In a control apparatus of an electric power steering apparatus structured such as to control a motor applying a steering assist force to a steering mechanism on the basis of a current command value calculated from a steering assist command value calculated on the basis of a steering torque generated in a steering shaft and a current value of the motor, it is always possible to execute a high-performance control regardless of a steering speed, by setting a first differential compensator and a second differential compensator inputting a steering torque, making a sampling cycle of the second differential compensator slower than a sampling cycle of the first differential compensator, and adding outputs of the first differential compensator and the second differential compensator to the steering assist command value.
摘要:
According to the present invention, in cases where a CHA function and a DKA function are mounted within a single package, a battery power supply that is used during the occurrence of power supply trouble is effectively utilized so that the supply of power can be separately controlled for each function. A CHA part and DKA part are disposed in a single control package. When trouble such as a power outage is detected, the CHA part blocks access requests from the host, and initiates end processing. When the end processing of the CHA part is completed, the package internal power supply control part stops the clock supply to the CHA part. Then, when the DKA part completes destage processing, the package internal power supply control part stops the supply of power to the DKA part. The power consumption of the package is lowered in stages in accordance with the progress of the end processing.
