Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings. FIG. 1 is a block diagram showing an operation mode display device of an image reproducing apparatus according to the present invention. Reference numeral 10 is an operation mode selection unit for inputting a selection signal of an operation mode selected by a user with various options. And a select button provided on a main body of a video reproducing apparatus such as a conventional VCR or VTR, or a select key provided on a remote controller to be controlled remotely.

12 is a receiving unit for receiving a selection signal input from the operation mode selecting unit 10, 14 is to operate the operation corresponding to the received operation mode output from the receiving unit 12 while controlling the operation of the entire apparatus A control unit for outputting a mode and operation performance signal, and preferably composed of a microcomputer.

16, OSD characters of various operation modes related to video tapes as information recording media handled by the image reproducing apparatus are stored and displayed on the basis of the operation mode execution signal outputted from the control unit 14. Is an operation mode OSD output unit that outputs an OSD character generation signal so that the screen is displayed in a flashing form, for example, EEPROM (Dynamic RAM).

18 stores graphics for various operation states for displaying the operation state of the video tape so that the graphic of the operation state corresponding to the operation state execution signal output from the controller 14 is displayed on the screen in a moving image. An operation state graphic output unit for outputting a graphic generation signal, for example, comprising an EEPROM.

20 shows the OSD text and graphics on the basis of the OSD text generation signal and the graphic generation signal output from the operation mode OSD output unit 16 and the operation state graphic output unit 18 under the control of the controller 14. And an image processor which outputs an OSD signal and a graphic signal for display and performs reproduction processing of a normal video signal reproduced on the video tape.

22 is a CRT (Cathod Ray Tube) device as a display device for displaying OSD text, graphics, and images based on the screen display signal and the image processing signal output from the image processing unit 20. For example, an OSD in which an operation mode flashes. An operation mode display window, which is an area of a predetermined position displayed in a text form, and an operation state graphic display window, which is an area of a predetermined position displayed graphically and displayed in an operation state for the operation mode.

Referring to the flowchart of FIG. 2, the operation mode display operation by the operation mode display apparatus in the image reproducing apparatus according to the present invention configured as described above is as follows.

First, after loading the video tape into a video reproducing apparatus such as a VCR or VTR, the controller 14 determines whether the received operation mode selection signal output from the receiver 12 is input in step S1. When no selection signal is input. On the other hand, if there is an input, the controller 14 determines the type of the selected operation mode in step S2 when there is an input of the operation mode selection signal.

In step S3, if the play mode is selected by determining whether the play mode is selected in the operation mode selector 10, the control unit 14 in the operation mode OSD output unit 16 in step S4. Outputs an OSD text generation signal to inform the user that the initial screen is on the basis of the operation mode execution signal. Accordingly, the image processing unit 20 flashes 'PLAY' or 'playback' according to the OSD text generation signal. OSD text is displayed on the operation mode display window installed at a predetermined position on the screen of the CRT 22, and the operation state graphic output unit 18 generates a graphic indicating an operation state for the current playback operation mode. The image processor 20 outputs a signal, and accordingly, the image processing unit 20 generates a mechanism in which, for example, a video tape according to the graphic generation signal is loaded by the loading motor and seated on the deck. The graphics are processed in a moving image to be displayed on an operation state graphic display window installed at a predetermined position on the screen of the CRT apparatus 22.

Then, in step S5, the control unit 14 determines whether the initial screen reproduction state is released and whether or not a normal video signal is input to the image processing unit 20. As a result, the initial screen reproduction state is maintained. If the normal image signal reproduced on the video tape is inputted while repeating the operation of step S4, the normal image processed by the image processing unit 20 on the CRT apparatus 22 in step S6. Will be displayed.

On the other hand, if the regeneration mode is not selected in step S3, it is determined whether the rewind or rewind mode is selected in step S7, and when the rewind or rewind mode is selected, The operation mode graphic is displayed on the screen of the CRT device 22, for example, 'FWD' or 'winding' in the form of blinking in the operation mode display window during the winding mode. In the display window, a graphic of a moving picture with a tape is displayed on the screen.In the rewind mode, the OSD text 'REW' or 'Rewinding' is displayed in the operation mode display window, and the operation status graphic display window is displayed. The moving picture on which the tape is rewound is graphically processed and displayed on the screen.

In step S9, the control unit 14 determines whether the graphic operation in progress of the moving image in the operation state graphic display window of the CRT 22 screen is completed, and if the operation continues, the operation of the step S8 is performed. On the other hand, if the operation is completed, the operation of step S6 is performed.

If the forwarding or rewinding mode is not selected in step S7, the operation of step S10, that is, the operation for the mode such as pause or stop, that is, in the case of pause, is reproduced on the CRT 22 screen. Since the image is displayed in the paused state, the operation mode display window and the operation state graphic display window do not appear. In the case of the stop, the CRT (22) is stopped because the playback function of the video reproducing apparatus such as VCR or VTR is stopped. The screen does not display any images, OSD characters or graphics.

Then, in step S11, the controller 14 determines whether the mode of the pause or stop is released, and if the mode is not released, the operation of step S10 is continued, whereas the mode is released. In this case, the normal image is displayed on the screen of the CRT 22 by performing the operation of step S6.

On the other hand, in the above description, the present invention is applied to an image reproducing apparatus such as a VTR or VCR as an example. However, the present invention can be suitably applied to a disc reproducing apparatus such as a laser disc player (LDP) having a relatively long initial delay time. .

According to the present invention as described above, by displaying on the screen of the CRT device the OSD character in the form of flickering for the corresponding operation mode and the operation state according to the operation mode when the initial image playback period and operation mode switching When the operation mode is changed, the operation mode is displayed from the display state of the monotonous background image displayed on the CRT screen, and the operation state OSD signal and graphic are displayed. Boredom over time can be eliminated.
