Image display device and control method for image display device

An image display device which displays an image on a display surface, the device comprising:

• a camera that functions as:
• a position detection unit which detects a designated position designated by a pointer on the display surface;
• and
• a distance detection unit which detects a distance between the display surface and the pointer;
• a processor that functions as:
• a determination unit which determines that an operation panel functioning as an operation unit provided on the pointer operated;
• a processing unit which carries out predetermined processing when it is determined that the operation unit operated;
• and
• a generation unit which generates a drawn image, based on a trajectory of the designated position;
• and
• a display unit which displays the drawn image on the display surface,
• wherein the processing unit carries out first processing when the distance is a first distance and it is determined that the operation unit is operated, and the processing unit carries out second processing which is different from the first processing when the distance is a second distance which is different from the first distance and it is determined that the operation unit is operated,
• wherein when a drawing mode for the generation of the drawn image is a first mode, the distance is the first distance, and it is determined that the operation unit is operated, the processing unit changes the drawing mode to a second mode which is different from the first mode, and when the drawing mode is the first mode, the distance is the second distance, and it is determined that the operation unit is operated, the processing unit changes the drawing mode to a third mode which is different from the first mode and the second mode, and
• the generation unit generates the drawn image in a form corresponding to the drawing mode changed by the processing unit.
