To this end, the user input unit 110 includes a plurality of operation keys, such as numeric keys, direction keys, confirmation keys.

In the present embodiment, the user input unit 110 is used to receive a step selection command for selecting a set OSD step. The OSD step is a step for the size of the OSD that is sequentially changed according to the user's setting. That is, the OSD step includes the step of making the existing OSD smaller or hidden. In more detail, it consists of a general step set to the original OSD size, a simple step reduced in size by the user's selection, and a hidden step not displaying the OSD. And a notification OSD in a feedback format for a user input.

The video signal input unit 120 receives an external video signal or obtains a video signal through reproduction of a recording medium. In more detail, an image signal is received through an external wired / wireless or a storage medium such as a magnetic tape / disk, an optical disk, a memory, or the like is acquired to acquire a stored image signal.

The image signal processor 130 processes the image signal received through the image signal input unit 120 into a viewable signal.

The storage unit 150 stores data and programs necessary for the operation of the image reproducing apparatus and the above-described OSD step.

The OSD unit 160 adds an OSD to the image signal processed by the image signal processor 130 and transmits the OSD to the display unit 170.

The display unit 170 displays an image signal to which the OSD transmitted from the OSD unit 160 is added.

The controller 140 controls the overall operation of the image reproducing apparatus according to a user command input through the user input unit 110 using a pre-stored control program.

In addition, the controller 140 sets an OSD step by input of a user command through the user input unit 110 and stores information about the same in the storage unit 150. In addition, the controller 140 changes and stores an OSD step stored in the storage 150 when receiving a step selection command through the user input 110. In addition, the controller 140 controls the OSD unit 160 to output the OSD to which the set / modified OSD steps are applied to the display unit 170.

This OSD step can be set through the menu screen. The OSD step may include a general step, which is a step set to an existing OSD size, a simple step, a step of which a size is set by a user's selection, and a hidden step, which does not display an OSD.

On the other hand, the type of OSD is classified into a selection OSD including a plurality of selection items, and a simple function and a notification OSD in a feedback format for a user input.

In addition, the selection OSD may be displayed as a bundle of a plurality of selection items and functions by selecting a menu or a function. This optional OSD does not apply hidden steps and can be composed of general and simple steps. In the case of the simple step, the size is reduced by displaying only the selected item among the selection items displayed in the general step. In the case of a simple step, the OSD size can be arbitrarily set by the user.

In addition, the notification OSD may display a function and image information changed according to a user's signal input as a channel, volume, image information, etc. in a feedback format for the user's input. This notification OSD can be composed of general steps, simple steps, and hidden steps. In addition, in the case of a simple step, it is set by reducing the size of the OSD. In the case of a simple step, the OSD size can be arbitrarily set by the user.

Hereinafter, a process of providing an OSD by the image reproducing apparatus illustrated in FIG. 1 will be described in detail with reference to FIG. 2. 2 is a flowchart provided to explain an OSD providing method according to an exemplary embodiment.

Referring to FIG. 2, first, the controller 140 determines whether an OSD display command is input from a user through the user input unit 110 (S201).

If it is confirmed in step S201 that the OSD display command is input (S201-Y), the controller 140 checks the type of OSD to display and the OSD step (S202).

In more detail, the controller 140 checks whether the OSD to be displayed for the user's input and the image information through the user input unit 110 and the image signal processor 130 is a selected OSD or a notification OSD.

In addition, the controller 140 checks an OSD step stored in the storage 150. The OSD step has been described above that there are general steps, simple steps, and hidden steps. Therefore, the step of OSD to be displayed may be applied by checking the OSD step stored in the storage unit 150.

Thereafter, when the OSD to be displayed is confirmed as the selected OSD (S203-Y), the controller 140 applies the OSD step identified in step S202 to the OSD to be displayed, and controls and outputs the OSD unit 160 (S205). .

The above selection OSD is a bundle of a plurality of selection items and functions, such as selection of a menu or a function, and does not apply a hiding step and may be composed of a general step and a simple step. In the case of the simple step, the size is reduced by displaying only the selected item among the selection items displayed in the general step.

On the other hand, when the OSD to be displayed in step S204 is confirmed as the notification OSD (S204-Y), the controller 140 applies the OSD step identified in step S202 to the OSD to be displayed, and controls and outputs the OSD unit 160. (S206).

The notification OSD is a feedback format for the user's input, such as channel, volume, image information, etc. may be displayed as a function and image information changed according to the user's signal input. This notification OSD can be composed of general steps, simple steps, and hidden steps. In addition, in the case of a simple step, it is set by reducing the size of the OSD.

As described above, according to the present invention, when the display of the OSD interferes with the video image, the type of OSD is divided into selected OSD and notification OSD, and according to each type, the user can perform general, simple, and hidden steps. By reducing or hiding the OSD depending on the selection, it is possible to reduce the overlapping with the main part of the image, which helps to enjoy a pleasant image.
