[Embodiment of the invention]

 Hereinafter, embodiments of the image reproducing apparatus of the present invention will be described with reference to the drawings. Fig. 1 is a block diagram of the device, Fig. 2 is a flowchart of an original screen creation program processed by the control unit of the device, and Fig. 3 shows the display contents of the screen selected by the screen selection input unit of the device. Fig. 4 is a diagram showing the contents of on-screen data set and input through the OSD setting input unit of the same device. Fig. 4 is a display in which the on-screen data shown in Fig. 3 is superimposed on the screen shown in Fig. 2. FIG.

The image reproducing apparatus A listed here is an apparatus for decoding and reproducing a compressed image recorded on a DVD disc 10 as a recording medium as shown in FIG. A television receiver, a monitor for a computer, and the like are connected to the device. Here, it is simply represented as monitor B. The image reproducing device A has an on-screen data display function. That is, a screen on which information such as time is superimposed on the image recorded on the DVD disk 10 is displayed on the monitor B. Hereinafter, the configuration of the device will be described.

The image reproducing apparatus A includes an optical disk reproducing unit 20 for reproducing a compressed image recorded on the DVD disk 10, a CSS code 21 for decoding digital data of the reproduced compressed image, A decoding unit 30 that decodes digital data of an image to obtain a decoded image, a video encoder 40 that converts the digital data of the decoded image into an analog video signal and outputs the analog video signal to the monitor B, and superimposes and displays the decoded image. The basic configuration includes an OSD generating section 50 for generating on-screen data, an operation section 60 for operating the entire apparatus, and a control section 70 for controlling the entire apparatus according to the operation section 60. Here, a microcomputer is used as the control unit 70. The operation unit 60 corresponds to an operation panel or a remote controller, through which operations such as power on / off, mode switching, and channel switching are performed. In the figure, reference numeral 90 denotes a memory unit in which a control program 91 and the like processed by the microcomputer of the control unit 80 are recorded in advance.

Here, as the OSD generation unit 50, one having a function of generating not only characters and symbols but also patterns and figures is used.

Although the description so far is no different from the conventional one, the present invention has been improved so that the existing on-screen data display function, that is, the original screen can be created by making good use of the OSD generator 50. Specific improvements are as follows.

First, in the operation unit 60, a mode setting unit 61 for switching to an original screen creation mode for creating an original screen, and a screen selection input unit 62 for selectively inputting one screen during image reproduction. The function as the OSD setting input section 63 for freely setting and inputting on-screen data to be superimposed on the screen selected through the screen selection input section is provided. Specifically, existing switches may be used or new switches may be added.

Further, a memory unit 80 for recording data of a screen selected through the screen selection input unit 62 is added. The memory unit 80 is provided before the decoding unit 30, specifically, between the optical disk reproducing unit 20 and the CSS decoder 21, in order to record the screen in a data format of a compressed image. Here, a flash memory, which is a nonvolatile memory, is used as the memory unit 80.

Further, in the original screen creation mode, the control section 70 reads out and reproduces the screen recorded in the memory section 80, and generates on-screen data as set and input through the OSD setting input section 62. The OSD generator 50 is controlled as described above. Since the control unit 70 is a microcomputer, a program as shown in FIG. 2 is added to exhibit this function. This program is previously recorded in the memory unit 90 as an original screen creation program 92. A plurality of types of on-screen data 93 are also recorded in the memory unit 90 in advance.

A description will be given of a method of creating an original screen by the image reproducing apparatus configured as described above, and also the contents of the original screen creating program 92 shown in FIG.

While the image recorded on the DVD disk 10 is being reproduced and displayed on the monitor B, the user stands still through the operation unit 60. Subsequently, when the mode is switched to the original screen creation mode through the mode setting unit 61 by the user, the control unit 70 processes the original screen creation program 92.

First, it is determined whether or not one screen during image reproduction is selected and input by the user through the screen selection input unit 62 (S1). When the screen is not selected and input through the screen selection input unit 62, the digital data of the compressed image output from the optical disk reproducing unit 20 is sequentially recorded in the memory unit 80 and is constantly rewritten. This is shown as a compressed image data storage unit 81 in FIG.

On the other hand, when a screen is selected and input through the screen selection input unit 62, the rewriting operation of the memory unit 80 is stopped at this timing. At the same time, the address of the memory 80 where the packet including the selected image is recorded is held (S2). As a result, even if the DVD disk 10 is taken out from the video reproducing apparatus A, the selected image can be reproduced.

Next, a setting input of on-screen data to be superimposed and displayed on the still screen is performed by the user through the OSD setting input unit 63 (S 3). The setting input of the on-screen data superimposed on the display screen on the monitor B is performed by the user selecting from the on-screen data 93 recorded in the memory unit 90 in advance. When the setting input of the on-screen data is performed, an instruction is given to the OSD generation unit 50 so that the on-screen data is generated as it is (S4). Then, the OSD generation unit 50 generates on-screen data according to the instruction, and outputs the on-screen data to the video encoder 40. As a result, the on-screen data is superimposed on the selected screen and displayed on the monitor B.

Then, it is determined whether the original screen creation mode has been canceled by the user through the mode setting unit 61 (S5). If not, the process returns to step 3 again. That is, as long as the original screen creation mode is not canceled, the processing after step 3 is repeatedly performed. Therefore, the content of the on-screen data superimposed on the display screen on the monitor B is set and input through the OSD setting input unit 63. It will change as needed.

For example, in consideration of using the original screen as the screen saver screen, if the on-screen data setting input as shown in FIG. 4 is performed through the operation unit 60, the screen of the monitor B will be as shown in FIG. Becomes

Thereafter, assuming that the original screen is created, when the user cancels the original screen creation mode through the mode setting unit 61, the final image of the memory unit 80 in which the packet including the selected image is recorded is stored. While the address is recorded in the address storage section 82 of the memory section 80, the setting content of the on-screen data is recorded in the on-screen data setting content storage section 83 of the memory section 80. (S6). Thus, the program shown in FIG. 2 is completed, and thereafter the original program is processed.

By using the original screen creation mode as described above, an original screen that suits the user's preference can be freely created within the range of the function of the OSD generation unit 50, and this can be used as a screen saver screen, wallpaper, or startup. It can be used as a screen. More specifically, in step 6, the compressed image recorded in the compressed image data storage unit 81 is read out from the address recorded in the address storage unit 82 of the memory 80, decoded and decoded to reproduce the on-screen data. The on-screen data is superimposed according to the settings of the on-screen data recorded in the content storage unit 83. If the control unit 60 exerts the above functions through the operation unit 60, the same original screen can be reproduced. Then, this is used as a screen saver screen, wallpaper or startup screen.

In the image reproducing apparatus configured as described above, the original screen can be freely created with only a slight improvement. Moreover, cost reduction and high performance in hardware can be achieved. A major addition in terms of hardware is the memory unit 80, which is provided between the optical disk reproducing unit 20 and the decoding unit 30 and records the data of the compressed screen. Only a small amount of memory can be used, and cost can be reduced.

The image reproducing apparatus of the present invention is not limited to the above embodiment, and may be applied to an apparatus for decoding and reproducing an image recorded on a video tape or the like. The type of the memory unit is not limited, and may be arranged at any position as long as a reproduced image can be recorded. The same function may be realized by hardware for the control unit.
