Next, with reference to FIGS. 5A and 5B described above, and FIG. 6 and FIG. 7A, FIG. 7B, and FIG. 7C, a user interface for creating content, playing it, and displaying information related thereto This will be described in detail.

In touch-operated smartphones, it is necessary to display buttons on the screen to call up “functions”. However, as such “functions” increase, the number of buttons increases accordingly. It has become difficult to understand the relationship between "functions", such as switching the operation.

Therefore, in the present embodiment, buttons for creating contents (content creation button set: camera call button 41, voice memo call button 42, video call button 43, FIG. 5A) and the corresponding contents of each are reproduced. Buttons for displaying the file information (content management button set: still image display button 45, audio playback button 46, moving image playback button 47, FIG. 5B) are prepared. Only one button set is displayed, and the display of each button set can be switched by the switching

buttons

44a and 44b. Each button is arranged so that buttons related to the same content are displayed at the same or corresponding positions (camera call button 41 ← → still image display button 45, voice memo call button 42 ← → voice playback button 46, video Call button 43 ← → video playback button 47, FIG. 6). As a result, the positional relationship among the button for the still image, the button for the sound, and the button for the moving image is maintained.

This makes it possible to reduce the area occupied by the button display, making it easier to place buttons within the range that can be listed, even on smartphones with a small screen, and improving the ease of searching for “functions”. And since the area occupied by the button display of “function” can be reduced, even a smartphone with a small screen can take a wide area for information display and work, improving usability. In addition, since the “function” for creating content and the “function” for managing the content are shown in pairs, the correspondence is easy to understand, and it is easy for the user to memorize the button positions and perform intuitive operations. There is.

Especially, taking a large button display area means that it can be called quickly even in an emergency. As part of the police service, you may have to shoot with a camera on your smartphone in an emergency. In that case, taking a large display area of the button has a great significance that it can be called quickly even in an emergency.

In the example shown in FIG. 5A and FIG. 5B, as shown in FIG. 7A, a switching button 44a having a button face “view gallery” and a switching button 44b having a button face “take content” are selected depending on the mode. An example of switching has been described. As shown in FIG. 7B, this may have one type of button face “switch” regardless of the mode.

Further, as shown in FIG. 7C, the color or luminance of the button face to be guided for selection may be changed and displayed as in the switching button 44d.

In addition, in the drawing, each button of the content creation button and the content management button is the same size, and it is determined which is the image on the button, but the button color and shape, the gap between the buttons The presence / absence may be switched so that the state of the content management button set can be easily recognized.

In the above embodiment, there is one type of content creation button for each still image, video, and audio. However, a plurality of content creation buttons can be set so that the application is activated with different settings for one content type. You may make it have the button of. For example, when a still image is taken, the camera call button 41 is one type, but it may be called in detail for each setting. For example, by calling such as “criminal shooting button”, “traffic accident scene shooting button”, “physical shooting button”, etc., it is possible to use the camera function of the optimal setting. As a result, it is expected that a system can be taken that allows rapid camera photography, particularly in an emergency.

In addition, when the smartphone power is turned on or when a predetermined condition for the operation suspension state is satisfied (no operation for a predetermined time, sleep mode, etc.), the content management button is displayed in the previous state. Even in such a case, it is desirable to switch the content management button set to the content recording button. This is because, when there is a sudden need to perform recording from the operation pause state, it is not necessary to check and switch the state of the content management button set, and the operation up to the start of recording is shortened.
