摘要： An image determination section determines whether an input image signal represents a bright image or a dark image. A control section switches between a first lighting mode in which the output of a power supply section is a first power value and a second lighting mode in which the output of power supply section is a second power value based on the determined result of the image determination section. The control section refers to a first table that contains data representing the relationship between the power value of the power supply section and the number of rotations of a cooling fan in the case in which the output of the power supply section is increased from the second power value to the first power value at a constant rate when the second lighting mode is switched to the first lighting mode.

摘要： An image display device includes a light source; a power supply section that supplies power to light source; a cooling fan that cools the light source; an input section; a drive section that supplies a voltage to cooling fan; a control section that controls drive section and power supply section. The control section sets a first power value for the output of the power supply section and also a first voltage value for the output of the drive section. The control section measures a time at which the light source has been lighted. If the measured value exceeds a threshold, the control section gradually increases the output of the power supply section up to a second power value that is greater than the first voltage value over a predetermined time.
