Abstract
A control method includes: causing a light modulator provided in a projection device to draw a drawn image including a first part having a first number of pixels; causing the projection device to project the drawn image as a projection image onto the projection target; causing an image pickup device to pick up the projection image including a second part corresponding to the first part and thus acquire a picked-up image; and determining a minimum width of stripe pattern including a bright part or a dark part detectable by the image pickup device, based on the first number of pixels and a second number of pixels, which is a number of pixels of a part corresponding to the second part of the projection image included in the picked-up image.
