Abstract
An image display apparatus includes an operation detecting unit, a display unit displaying an image, and a controller. The operation detecting unit receives drawing operations performed with electronic pens and state signals indicating operation states of the pens. The controller generates drawing data in response to each drawing operation, displays setting menus for the pens and the drawing data on the display unit, and determines whether each pen is being operated. From each pen, the operation detecting unit receives, as the state signal, a signal indicating whether the pen is moved or indicating the degree of the speed of a movement of the pen. The controller determines whether each pen is being operated based on the state signal. When the pen is being operated, the setting menu for the pen is displayed in a display mode depending on the degree of speed of the movement.
