  According to the technique described in Patent Document 1, the setting data, the song data, and the image data are associated with the removable memory card, and there is a problem that the degree of freedom in selecting the background image is low. In the general apparatus shown in FIG. 7, only a background image stored in the internal memory can be selected.

  FIG. 8 is a diagram illustrating an example of a background image selection display on a general menu screen. As shown in FIG. 8, images 121 on eight background image selection display screens are read from the internal memory area and displayed on the screen 107. Currently, the image (1) 111 is selected, and the image (1) 111 is a selection image. Here, when the determination process is performed, the image (three rhombuses) of the image (1) 111 is selected as a background image of a menu screen (not shown) as the next screen.

  When such a background image, icon, etc. using a general TV OSD are incorporated in the television, the memory capacity used for the incorporation of the image increases, or the user uses a fixed image for the fixed image. There was a problem of narrowing the selection range.

  An object of the present invention is to reduce the capacity of a built-in memory and widen the range of user selection regarding a background image.

  In the present invention, for example, a default image of the content display device is stored in the memory area 27a for the internal background image. The external background image memory area 27b stores image data that has been stored in a storage medium such as a memory card, which will be described later, and that has been transferred from the memory card or the like to the apparatus and taken into the apparatus. .

It is a functional block diagram which shows one structural example which used the television receiver for the general content display apparatus as an example. It is a flowchart figure which shows the basic flow of the selection process of the background image in the general content display apparatus shown in FIG.

  Hereinafter, a content display device according to an embodiment of the present invention will be described using a digital broadcast television receiver as an example. As shown in FIG. 1, the content display apparatus according to the present embodiment receives a front-end circuit 1 that performs reception processing of a broadcast wave received from an antenna, and receives the output to separate into program information and broadcast data. Demultiplexer 3, program information decoding unit 11 for decoding program information, video / audio decoding unit 5 for decoding video / audio data, audio output unit (speaker) 7 for outputting decoded audio, and OSD data An OSD data generation unit 15 to generate, a screen synthesis unit 17 that synthesizes program information, OSD data, broadcast data, and the like, and a display unit (display) 21 that displays the screen-synthesized video are included. Further, an interface 2, a remote control light receiving unit 23, a control unit (CPU) 25, and a memory unit 27 are provided. The interface unit 2 includes, for example, an external memory interface 2a, an external device interface 2c, a network interface 2d, and the like, and can acquire information from the outside.

  The memory unit 27 includes a nonvolatile memory, a hard disk, and the like, and includes an internal background image memory area 27a for storing an internal background image and an external background image memory area 27b for storing an external background image. ing. In the internal background image memory area 27a, for example, a default image of the content display device is stored. The external background image memory area 27b stores image data that has been stored in a storage medium such as a memory card, which will be described later, and that has been transferred from the memory card or the like to the apparatus and taken into the apparatus. .

  The control unit 25 includes a background image selection processing unit 25a that provides a user interface for selection as a background image, and a menu display control unit 25b that performs display control of menu display on the display device. Generally, these display controls are executed by processing of a program stored in the memory unit 27.

  Hereinafter, background image selection processing in menu display will be described. FIG. 2 is a flowchart showing a background image selection process in the control unit 25 based on an image from an external memory in the display device according to the present embodiment, in addition to a general background image selection process. Here, an image stored in a USB memory as an external memory will be described as a target example.

  As shown in FIG. 2, when the process is started (step S1: Start), when it is detected in step S2 that the USB memory is inserted into the external memory interface 2a (YES), the process proceeds to step S4, and the USB memory It is determined whether or not an image file exists in the file (a movie file may be used). On the other hand, in the case of No, an image may be read from the internal memory (when there is some instruction from the input unit).

  The process proceeds from step S3 or step S5 to step S6. In step S6, a background image selection screen on the menu screen is displayed. Here, in step S7, the user's selection operation is awaited (Yes), and in step S8, the image selected in step S7 is assigned as a background image, and the process ends (END: step S9). In order to identify an image (still image, moving image) or the like from data from the external memory, it can be distinguished by, for example, a data identifier (jpeg, mpeg, etc.). The background may be confirmed by actually displaying it on the screen.

  Through the above processing, the image from the external memory or the like and the image stored in the default can be used for the background image of the menu display of the content display device without being separated.

  FIG. 3 is a flowchart showing the flow of the menu screen display process before and after the background image selection process in the content display device according to the present embodiment. The process proceeds from step 8 in FIG. 2 to step S11, where the background image can be confirmed by enlarging the selected background image on the menu. Next, in step S12, an operation for determining the background on the menu screen is performed ( Store background image in memory). Then, in step S13, when the menu background image is selected and the screen returns to the selection screen, the image selected immediately before is easily displayed, such as the image selected immediately before being enlarged. Make it identifiable. Thereby, it is possible to easily know which image was the last selected image.

  FIG. 4 is a flowchart showing an example of data processing in the internal memory according to the background image selection processing in the content display device according to the present embodiment. From step S5 in FIG. 2 to step S15, an image from an external memory such as a USB memory is stored in the internal memory 27b of the apparatus main body. Next, the processing from step S6 to S9 in FIG. 2 is executed. In step S17, the image data from the USB memory stored in the internal memory after the assignment is deleted, and the processing is terminated (step S9). By erasing image data fetched from an external memory such as a USB memory into the internal memory every time or the like, it is possible to prevent the internal memory from being occupied by the image data fetched from the external memory. In particular, when a moving image is used as a background, that is, when a background is displayed based on data having an identifier of a moving image, since the memory occupies a large amount, one selected moving image data is stored in the internal memory. It is preferable to transfer and store only the video, and based on this, the video is used as the background. In addition, when the moving image is used as the background and the menu display is completed, the occupied capacity of the internal memory in the apparatus can be reduced by immediately deleting it from the internal memory.

  An image acquired from the external memory does not necessarily have a display area that matches the menu screen. Therefore, it is preferable to match the display area of the menu screen. As a method in that case, there are a method of simply extending an image so as to adjust the size, a method of adjusting a display size by arranging a plurality of images, and the like. When arranging a plurality of images, a method of arranging a plurality of the same images, a method of arranging a plurality of different images, or the like can be used. In general, arranging different images will result in a cleaner image, but there may be a case where different images are arranged, for example, as in the case of images of the same target having a different time series. These are preferably made selectable by the user. In the case of a moving image, a background image may be created using a still image obtained by cutting out the moving image at certain timings.

  FIG. 5 is a flowchart showing an example of background image display processing in the case of a selection image with a low resolution in the background image selection processing in the content display device according to the present embodiment. In the case of an image with a low resolution, if it is enlarged and used as a background, the resolution is further lowered and it becomes difficult to see. Therefore, as shown in FIG. 5, it is determined in step S18 whether the resolution of the image is lower than a certain reference value. If No, the process proceeds to step S5. If YES, the process proceeds to step S19, and the same background is repeatedly displayed at different positions on the image. Thereby, it is possible to obtain a visual effect as if the background image was enlarged while maintaining the resolution. Note that a mode in which low-resolution data is repeatedly displayed on the display screen and a mode in which the low-resolution image is displayed on the entire display screen may be switched and used. Both background images may be compared and selected by the user.

  FIG. 6 is a diagram showing an example of a display screen for performing background image selection processing in the content display apparatus according to the present embodiment. On the screen 21, here, eight images from image 1 to image 8 are displayed as selection candidates. The currently selected image (1) 61 is displayed larger than the other images. Then, the image 1 is displayed as a background image (71a, 71b, 71c). When image 2 is selected, the background image changes. Accordingly, the background image changes when the selection candidate image changes due to a user operation or the like (which may be automatically changed), so it is possible to easily know which is preferable as the background image.

  In the above example, selection of the background image on the menu screen has been described. However, an icon or the like used on the menu screen can be used as image data. Further, both the image in the internal memory and the image in the external memory may be displayed and selected. A background image in which both images are superimposed and displayed by OSD processing may be used. As a result, an original menu screen can be created and customized in various ways. The menu image and the background image are generally associated with each other. The menu display associated with the image captured from the external memory is associated, and the same background image can be displayed as long as there is no change. If a moving image is used as a background image, the state of the image can be changed.

  A memory card storing an image suitable for the content display device may be used as a product. As a result, a background image selected from only background images suitable for the content display device can be obtained. A USB memory or the like may be provided as an accessory without having a background image inside. It may be provided via a network from a URL. The content source of the content display device includes all broadcast waves, content via a network, content on a storage medium, and the like.

  In the above-described embodiment, the configuration and the like illustrated in the accompanying drawings are not limited to these, and can be changed as appropriate within the scope of the effects of the present invention. In addition, various modifications can be made without departing from the scope of the object of the present invention.
