<p>PURPOSE: A screen enlargement/reduction method of an image processing device including a touch input unit and the image processing device for performing the method are provided to enlarge or reduce a screen by only a simple touch input on the touch input unit by considering touch pressure, thereby improving convenience. CONSTITUTION: An image processing device detects a touch input(S101). If the touch input is detected at a specific point on a touch input unit, the image processing device senses a touch state change of the touch input(S103). Based on the touch state change, the image processing device enlarges or reduces a screen of the image processing device(S105). The touch state refers to a contact area and/or touch pressure. If the contact area is increased, the screen is enlarged. If the contact area is contracted, the screen is reduced.</p> |
