Field of the Invention
Methods and apparatuses consistent with the present invention relate to display, image processing control, and more particularly, to a display apparatus, an image processing apparatus and a control method thereof, which can adjust a size of a UI menu item of a user interface according to a user's preference.
Description of the Related Art
Generally, a display apparatus such as a TV, a mobile phone, a Personal Digital Assistant (PDA), and a Portable Multimedia Player (PMP) displays a user interface (hereinafter referred to as “UI”) to select a UI menu item on a screen. At this time, the user interface may include UI menu items that may be formed in various types. For example, the UI menu items may be arranged in a horizontal and/or vertical line. UI menu items, each of which has a text list, may also be formed. UI menu items, each of which has a label, may be formed in two dimensions. UI menu items, each of which has an elliptic shape or a circular shape to rotate, may be formed.
In a conventional art user interface, there are various methods by which a user may select a UI menu item. For example, the user may typically use a moving highlight or a fixed highlight to select a UI menu item by manipulating buttons up and down and/or right and left.
However, depending on the conventional art user interface, a size value of a UI menu item to be displayed on a screen is preset so that the UI menu item having a constant size corresponding to the preset size value is always displayed. Accordingly, if a plurality of UI menu items with constant size are formed, when a current-highlighted UI menu item is far away from a desired UI menu item, highlighting the desired UI menu item may be complicated. In particular, when the UI menu includes a lot of UI menu items, a problem may occur when highlighting the desired UI menu item.
Further, according to the conventional art user interface, as described above, the size value of a UI menu item to be displayed on a screen may be preset regardless of the user's preference. Accordingly, the user cannot select a desired UI menu item directly and easily. In particular, when a child or an impaired adult tries to select a desired UI menu item, they may have trouble accessing and controlling their user interface because it takes time to become familiar with how to access and control the user interface without adequate explanation.
If an input means such as a touch screen is employed, when the UI menu item includes a preset small size value, it is difficult to exactly select a desired UI menu item without inconvenience. Conversely, even if the UI menu item has a preset size value that is large, the user interface includes limitable UI menu items that can be displayed on a screen at once so that the user interface may not display all desired UI menu items at once.
