Embodiment Construction

[0029] Next, a method of controlling a projector and the projector according to an embodiment of the present invention will be described with reference to the drawings. figure 1 It is a block diagram showing the configuration of the projector 1 . As shown in the figure, the projector 1 has a signal input unit 11, an operation unit 12, a power supply unit 13, an optical unit 14, a cooling unit (cooling unit) 15, a temperature detection unit (temperature detection unit) 16, and a control unit (control unit). )17.

[0030] The signal input unit 11 acquires image data from an external device 21 such as a personal computer or a video recorder. In addition, instead of acquiring image data from the external device 21, image data and the like may be acquired from an external storage medium (not shown).

[0031] The operation unit 12 has an operation panel 22 and a remote control light receiver 23 . The operation panel 22 is provided on the main body of the projector 1 and has a gro...

Abstract

The present invention relates to a projector and a projector control method. A projector which includes: a light source lamp (31); a cool down unit (15) which performs a cool down process for the light source lamp (31); a mode selection unit (12,17,61) through which a normal mode for executing the cool down process at the time of power off or a special mode for eliminating the cool down process at the time of power off is selected; and a control unit (17) which controls the light source lamp (31) and the cool down unit (15) based on the result of the mode selection determined through the mode selection unit (12,17,61).Therefore, various use methods can be flexibly coped, without reducing the convenience of the projector.

Description

technical field [0001] The present invention relates to a projector and a control method of the projector for projecting images using a light source lamp composed of a high-intensity discharge lamp. Background technique [0002] Conventionally, as such a projector, there is known a projector which includes a cooling unit for cooling a light source lamp and performs the cooling process when the power is turned off (see Patent Document 1). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2007-47387 [0004] However, in such a projector, since the cooling process is performed when the power is turned off, it takes a while until the power supply is stopped. For example, when the use of the projector is finished, the projector is often put away immediately. In this case, it is necessary to wait for the cooling process to be completed before putting away, so there is a problem that the convenience of the projector is reduced. [0005] On the other hand, although the met...
