Projection-type display device and method for adjusting a projected image

A projection-type display device that allows adjustment of a projected image, comprising:

• a processor;
• and
• a memory coupled to the processor, the memory storing instructions to cause the processor to perform:
• receiving, by an operation signal detector, an operation signal that indicates adjustment content of said projected image that was instructed;
• detecting, by an installation state detector, as an installation state of said projection-type display device, a first state and a second state that is rotated 90 degrees from said first state around an axis that is parallel to an optical axis of a projection lens;
• and
• adjusting, by a controller, upon detecting a signal that corresponds to a first direction by way of said operation signal detector in said first state and said second state, said projected image by causing said projected image to shift in said first direction, or adjusting said projected image by causing a correction-object site in said projected image to move in said first direction, wherein:
• said controller, when said projection-type display device is changed from said first state to said second state, exchanges a breadth of an adjustment range which is instructed in left-right directions of said projected image and a breadth of an adjustment range which is instructed in up-down directions of said projected image.
