Description

How to display the menu on screen in an imaging system

The present invention relates to a method of displaying a menu on a screen of an imaging system, and more particularly, to a method of displaying a menu by an on-screen display method.

In general, a system that can display an image such as a TV (TeleVisoin) receiver or a PC (Personal Computer) is used such as an OSD (On Screen Display) or OSG (On Screen Graphic) so that users can easily understand and use various functions. By using the on-screen function, a menu corresponding to each function is displayed on the screen. The menu items displayed as described above are selected by the user using a remote control, a keyboard, or a pointing device such as a mouse and a joystick.

A method of displaying a menu using the OSD and allowing a user to select a menu will be described with reference to the accompanying drawings. FIG. 1 is a schematic block diagram of a general on-screen display generating circuit applied to an imaging system, and FIG. 2 is an exemplary view for explaining a general menu on-screen display method.

The circuit for generating an OSG with reference to FIG. 1 is largely comprised of a font memory 2 and an OSG control unit 6. The font memory 2 stores fonts such as letters or icons to be displayed on the screen, and the OSG control unit 4 stores bitmap data of characters or icons to be displayed on the screen from the font memory 2 in response to an applied control signal. Read it and print it to the screen.

On the other hand, the control signal may be applied from a control unit in charge of the overall control of the imaging system, the control unit based on the input signal by the user in the process of selecting a menu using the remote control, keyboard or pointing device, etc. In order to facilitate the user's menu selection, the control signal is applied to adjust the shape of the menu output to the OSG.

For example, when a user selects a menu using a pointing device, a user specifies a corresponding menu item by adjusting a pointing device while positioning a cursor on a desired menu item while looking at a cursor indicating a pointing position of the pointing device on a screen. . At this time, the designated menu item is displayed in the selectable state. The display of the selectable state is performed by changing the color of the OSG or by inverting the phase of the OSG. Referring to FIG. 2, it is illustrated that "ICON2" becomes a selectable state among a plurality of menus on the screen 6. In this state, when the user clicks an execution key of the pointing device or inputs an enter key on the keyboard to select the menu item again, the function of the menu item is executed.

As described above, in the conventional menu display, the display of the menu item which has become a selectable state is simply displayed by changing or inverting the color, and thus the recognition of the menu selection is not strengthened. Since the color and the like are considered to be the easiest to be recognized by the user, the color change and the reverse of the menu item may make it more difficult for the user to recognize the characters or icons of the menu as described above.

Accordingly, an object of the present invention is to provide a menu on-screen display method in an image system capable of strongly recognizing a menu selection.

Another object of the present invention is to provide a menu on-screen display method in an image system capable of recognizing selection of a menu item without applying color change and inversion of the menu item.

In order to achieve the above object, the present invention provides a menu on-screen display method of a video system for displaying a plurality of menu items in OSG, the menu item desired by the user through the menu selection device from the user And a process of selecting and converting the border color of the selected menu item to display the selected menu item.
