摘要： An image display device has a light source; a power supply section that supplies power to a light source; a cooling fan that cools the light source; a input section; and a control section that controls the cooling fan and the power supply section. If a first lighting mode in which a power value supplied to the light source is a first setting value is designated through the input section, the control section causes the power supply section to supply power that corresponds to the first setting value to the light source and causes the cooling fan to operate.

摘要： An image display device has light source (3); power supply section (2) that supplies power to light source (3); cooling fan (4) that cools light source (3); input section (5); and control section (1) that controls cooling fan (4) and power supply section (2). If a first lighting mode in which a power value supplied to light source (3) is a first setting value is designated through input section (5), control section (1) causes power supply section (2) to supply power that corresponds to the first setting value to light source (3) and causes cooling fan (4) to operate. If a second lighting mode in which the power value supplied to light source (3) is a second setting value that is smaller than the first setting value is designated through input section (5), control section (1) causes power supply section (2) to supply power corresponding to the second setting value to light source (3) and causes cooling fan (4) to stop.

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.
