Abstract: An image projection apparatus according to an embodiment of the present invention senses the distance to an image projection area to which an image is projected, and determines an image projection state including a state of at least one of the image projection area and a space between the image projection apparatus and the image projection area, on the basis of the sensed distance. The image projection apparatus projects an image onto the image projection area on the basis of the determined image projection state.

Abstract: A method of controlling an air conditioner including activating a refrigeration cycle by driving an compressor; detecting a high pressure and a low pressure when the refrigeration cycle is activated; adjusting an operating frequency of the compressor based on the detected high pressure or low pressure of the refrigeration cycle; determining a current load of an inside space through a load detecting unit; determining a load level of the inside space by comparing the current load with a reference load; and determining the operating frequency of the compressor based on the determined load level.
