Description

O-S-D background color control method and device

The present invention relates to a method and a device for controlling an on-screen display (OSD) on a OSD-based OSD TV. In particular, the present invention relates to a TV screen that is too large due to the menu of the OSD (MEUN). The present invention relates to an O-S-D background color control method and apparatus for removing background color and displaying only text when a TV screen content is almost hidden.

Generally, OSD is divided into OSD position change mode, OSD size change mode, OSD background color control mode, OSD color change mode, and OSD brightness change mode.

The present invention is to propose an OSD background control mode to control (on / off) a variety of OSD background colors according to the user's taste in a menu-type OSD TV.

A typical conventional OSD is shown in FIG. The conventional OSD shown in FIG. 1 has a remote controller 100, a microcomputer 200 for controlling the image and sound coming out of the remote controller, and an RGB OSD color signal controlled by the microcomputer to process the image and output the image signal to the CRT. It consists of an image processing unit 300.

Such a conventional OSD controls the image and sound output from the remote controller 100 with the microcomputer 200, and when the RGB OSD color signal for the OSD signal controlled by the microcomputer is applied to the image processing unit 300, the image processing unit 300 Outputs the RGB color signal processed by the CRT.

However, this conventional OSD, because the TV screen is too much obscured due to the menu, the user can not see the contents of the TV screen when adjusting the screen, so that the user was inconvenient.

The present invention has been made to solve the above-described problems, the OSD screen in the OSD TV is too much screened by the OSD of the OSD screen is too much to see the contents of the TV screen to remove the OSD background color only to make the user uncomfortable To solve the problem.

In order to achieve the above object, the present invention provides an OSD mode checking step of checking whether the microcomputer is in the OSD change mode by the remote control, and ending the OSD change mode if it is not in the OSD change mode. The background color mode step, if not in the OSD background change mode, and the OSD background change mode, the background color on / off step to turn on / off the various OSD background colors according to the user's taste, and the background color removal step to remove the background color when the background color off It is characterized by consisting of a character display step of displaying only letters on the TV screen when the background color is removed.

In addition, the present invention is characterized by configuring the OSD background color control unit for controlling the OSD background color.

Hereinafter, the configuration according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

2 is a block diagram of the present invention for OSD background control, as shown in Figure 2, the remote control 100, the microcomputer 200 for controlling the image and sound coming out of the remote control, and the RGB OSD color signal controlled by the microcomputer In the OSD configured by the image processing unit 300 for outputting an image signal to the CRT by image processing, the OSD includes a OSD background color control unit 500 for controlling the OSD background color.

FIG. 3 is a detailed block diagram of the OSD background color control unit of FIG. 2. The OSD background color control unit 500 stores the RG and B color signals controlled by the microcomputer 200 as shown in FIG. OSD background color control register 10 for instructing the display generator, display generator 60 for displaying according to commands received from the background color control register, and timing section 20 for setting timing to change the horizontal / vertical position on the OSD. ), A ROM 30 that stores or exports all the text programs required on the OSD, a ROM 40 that stores all the programs required on the OSD, and a RAM 50 that reads or writes the programs instantly. do.

4 is an OSD adjustment menu diagram displayed on a TV screen, wherein the standard shown in FIG. 4 is a standard mode selected by the operator at the time of shipment, 2 is a selection mode when compositing into two colors, and 3 is a synthesis of three colors. The selection mode and level are OSD brightness adjustment modes for adjusting the OSD background color and text level separately, and a separate menu OSD standard off key and menu OSD zoom key are added to the remote control.

FIG. 5 is a flowchart according to the present invention. As shown in FIG. 5, when the TV is turned on, the microcomputer performs an OSD mode check step (S200) for checking whether the OSD change mode is performed by the remote controller and terminates the OSD change mode. Mode, OSD brightness mode step (S300) to check whether the OSD background change mode, and if not the OSD background change mode, and if the OSD background change mode, the background color on / off to turn on / off the various OSD background colors according to the user's taste Step S400, a background color removal step (S500) to remove the background color when the background color off, and a character display step (S600) to display only letters on the TV screen when the background color is removed.

Referring to the operation and effect of the present invention configured as described above, first, as shown in Figure 2, 500 is an OSD background color control function for controlling the OSD background color, a detailed view of the OSD desktop control unit 500 is shown in FIG. As shown in FIG. 3, the microcomputer 200 first controls an image and a sound according to a command issued to the remote controller 100. Therefore, the OSD background color control register 10 stores an RGB color signal to display a conversion of the necessary RGB color signal. Command the generator 60. The commanded display generator 60 outputs the OSD color signal. In the drawing, reference numeral 20 denotes a timing unit for determining timing to determine the horizontal / vertical position of the OSD, 30 denotes a character ROM which stores or exports all character programs required on the OSD, and 40 denotes all programs necessary on the OSD. 50 is a RAM that reads or writes a program momentarily. Now, a detailed description will be made based on the flowchart of FIG. 5. First, when the TV is turned on (S100), the microcomputer 200 checks whether the remote control is in the OSD change mode (S200) and exits if it is not in the OSD change mode. Check (S300). If the OSD is not in the color changing mode, and exits, if the OSD is in the color changing mode, depending on the user's taste, various OSD color is turned on / off (S400). Therefore, when the background color is turned on, the OSD background color register 10 stores the OSD background color adjusted by the microcomputer 200 and instructs the display generator 60 of necessary background color conversion. At the same time, the display generator 60 processes the OSD background image and transmits the OSD background color to the CRT, thereby adjusting various OSD background colors according to the user's preference in the menu-based OSD TV. Therefore, when the background color is turned off, the OSD background color is removed (S500) and only the letters are displayed on the TV screen at the same time as the background color is removed (S600).

The present invention operated as described above provides an OSD background color control device, so that the TV screen is too much obscured by the OSD's menu background in the OSD TV, so that the background color is removed and only letters are visible in a state where the TV screen contents are almost invisible. It is effective in relieving discomfort.
