The present invention relates to an imaging apparatus, and more particularly, to an apparatus and method for selecting an external input source of an imaging apparatus for controlling selection of an external input source of an imaging apparatus.

In general, a video device is a device for displaying information as an image using a screen, and a typical video device includes a television (TV) for receiving an electric wave of a broadcasting station and displaying an image.

In the conventional video apparatus, the selection of an external input source is performed by operating an information key, an information selection key, a cursor up / down key, and a decision key.

1 is a block diagram showing a conventional external input source selection device, Figure 2 is a block diagram showing a conventional external input source selection method, Figures 3a and 3b is a conventional external input source selection screen display.

As shown in the drawing, the conventional external input source selection device displays an external input signal selected by the switching element 10 on the screen via the video process 20 and the CRT drive 30. The switching element 10 is a microcomputer. The external input source can be selected by the control of 40, and the microcomputer 40 recognizes the control signal of the remote controller to control the switching element 10 and applies the OSD screen display signal to the bidet access process 20. .

Here, the microcomputer 40 applies OSD data to the bidet process so that the external input source selection screen is displayed on one side of the main screen as shown in FIG. 3A when the A / V key is pressed and the external input source selection screen is displayed. Pressing the A / V key again will cause the external input source to be up / down and be selected as previously programmed, and display the selected external input source on the screen.

In addition, when the information key is input, the microcomputer 40 displays a source information screen on which a selectable external input source is displayed as shown in FIG. 3B, recognizes a cursor up / down key input, and moves a cursor in the source information screen to select an external input source. When the decision key is input after selection, the cursor selects the selected external input source to display on the screen.

The switching element 10 switches the external input source selected by the user among the external input sources by the control of the microcomputer 40 and applies it to the bidet process 20.

The OSD display of the screen according to the selection process of the external input source is determined by the microcomputer 40 and the microcomputer 40 displays a corresponding operation screen on the screen when a key is required for selecting the external input source.

In this prior art, we first look at the process of selecting an external input source using the A / V key.

When the A / V key is input, the microcomputer 40 displays the external input source selection screen as shown in FIG. They are converted sequentially as shown and displayed on the screen.

When the A / V key input is lost for about 2 seconds, the external input source selection screen disappears and the selected external source is displayed.

In addition, an external input source is selected by looking at the source information screen as shown in FIG. 3B. When an information key is pressed in the A / V mode, the source information screen is displayed. Is displayed so that the user can check the selectable external input source at a glance.

After being displayed on the source information screen as shown in FIG. 3B, the cursor is moved up / down using the cursor up / down keys, the desired external input source is selected, and when the selection is completed, the decision key (0K) is input to select and display the external input. Meanwhile, the source information screen disappears.
