Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing a schematic configuration of a head mounted display (hereinafter referred to as “HMD”) as an example of an embodiment of the present invention.
As shown in FIG. 1, the HMD 100 includes a main body 1 that is mounted on the head, a control unit 2 that is mounted on a portion other than the head, a media player unit 3, and an operation unit 4. .

  The main body 1 has a display element 5 formed of an LCD for forming an image, a backlight 6 for applying light to the display element, and an LCD driver 7 for operating the LCD. The control unit 2 includes a CPU 8 that controls the entire control, an image processing unit 9 that performs image processing, a frame memory 10 that stores image signals from the media player unit 3 and sends them to the image processing unit 9, a timer circuit 11, and a CPU 8 A player controller 12 that controls the media player unit 3 in response to a signal from the receiver, a receiving unit 13 that receives information wirelessly from the outside, and a storage unit 14 that stores advertisement information, which will be described later.

In a normal state, the image signal from the media player unit 3 is processed by the image processing unit 9 via the frame memory 10, and the LCD driver 7 is activated by the control signal from the image processing unit 9 and should be displayed. An image is formed on the display element 5. The image formed by the display element 5 is projected onto the user's eyes by an optical system (not shown).
HMD100 of this Embodiment displays the image which shows advertisement information on the display element 5, calling a user's attention during observation of a normal image.

First, the acquisition of advertisement information will be described.
The advertisement information is information prepared in advance on a server on the Internet, and is prepared by an advertiser. The advertisement information includes image data such as moving images and still images, character data, audio data, and the like. Further, the advertisement information includes attribute information related to time, region, and the like.

  Such advertisement information is acquired by the user via a computer in which the HMD 100 and the Internet are connected at home or the like, or the HMD 100 is acquired via the receiving unit 13 when away from home. The CPU 8 temporarily stores the acquired advertisement information in the storage unit 14. When the advertisement information is acquired on the go, the advertiser's store or an existing access point can be considered as the transmission source.

In any case, a plurality of advertisement information may be acquired at the same time. In this case, selection information (details will be described later) used for display may be associated with each advertisement information as attribute information.
Next, the timing for displaying advertisement information will be described.
The CPU 8 displays advertisement information on the display element 5 at a timing based on a user instruction via the operation unit 4 or at a timing based on a timing signal. The timing based on the user instruction via the operation unit 4 is when the user gives an instruction via the operation unit 4 when it is desired to display advertisement information. When the CPU 8 detects such a user instruction, the CPU 8 reads the advertisement information from the storage unit 14, performs image processing by the image processing unit 9, operates the LCD driver 7, and displays an image to be displayed on the display element 5. Form.

  On the other hand, the timing signal is a signal indicating the timing at which the advertisement information is displayed on the display element 5. The CPU 8 acquires this timing signal simultaneously with the advertisement information or separately. The timing signal includes a signal indicating a time (for example, “after 5 minutes”) from when the advertisement information is acquired to display and a time (for example, “10:30”) for displaying the advertisement information. There is a signal to show. Note that the CPU 8 controls the timer circuit 11 based on these timing signals to display advertisement information.

As described above, when the user acquires advertisement information via a computer in which the HMD 100 and the Internet are connected at home or the like, the timing signal may be acquired at the same time. Further, as shown in FIG. 2A, only advertisement information may be acquired in advance at home or the like, and a timing signal may be acquired via the receiving unit 13 at a place where the user is away.
Further, as described above, when the advertisement information is acquired via the receiving unit 13 when going out, the advertisement information and the timing signal may be acquired simultaneously as shown in FIG. 2B. Further, as shown in FIG. 3, the advertisement information may be acquired via the receiving unit 13 at a certain point, and the timing signal may be acquired via the receiving unit 13 at another point. In any case, when the timing signal is acquired on the go, an advertiser's store or an existing access point may be considered as the transmission source.

In addition, when a plurality of pieces of advertisement information are acquired together, the advertisement information selected according to the user instruction or the timing signal may be displayed. Specifically, the advertisement information to be displayed on the display element 5 may be selected from the plurality of advertisement information acquired collectively based on the selection information described above.
In any case, when an image such as a movie based on an image signal from the media player unit 3 is displayed on the display element 5, the CPU 8 switches the image indicating the advertisement information simultaneously with or switching to the image being viewed. To display. FIG. 4 shows a display example when displaying simultaneously. For example, as shown in FIG. 4, the CPU 8 superimposes and displays an image (i1) indicating advertisement information on the image being viewed. At this time, in order not to interrupt the viewing of the image, the image (i1) indicating the advertisement information is preferably displayed by providing a small window or the like in the image being viewed.

  Furthermore, as shown in FIG. 5A, an image being viewed and an image (i2) indicating advertisement information may be displayed in parallel. Further, as shown in FIG. 5B, a window may be provided in a part of the image being viewed, and the image (i3) indicating the advertisement information may be displayed within the window as a telop. Further, as shown in FIG. 5C, the background of the image (i4) indicating the advertisement information may be made transparent and superimposed on the image being viewed.

In addition, if an image indicating the advertisement information is always displayed or kept displayed, the original appreciation is hindered, and therefore, it is preferable to display in a short time such as only for a certain time. Further, when displaying an image indicating advertisement information, the image being viewed may be temporarily stopped.
In addition, in order to prevent the user from being surprised or uncomfortable by displaying an image indicating the advertisement information suddenly, as a configuration for notifying that the image indicating the advertisement information is displayed using voice information, an image icon, etc. Also good. Further, the image indicating the advertisement information may be displayed gradually darker. Further, an icon or the like indicating that advertisement information exists may be displayed, and a specific image may be displayed after an execution instruction is given by the user.

The advertisement information may be displayed even when the user is not watching a movie using the HMD 100. Further, after displaying an image indicating the advertisement information on the display element 5, the advertisement information may be stored in the storage unit 14 or may be deleted after the display.
Finally, a display method for displaying advertisement information more effectively will be described.
The first method is a method of changing at least one of luminance, contrast, and γ correction value edge enhancement degree of an image showing advertisement information over time. While displaying the image indicating the advertisement information, the CPU 8 controls the image processing unit 9 and the backlight 6 so that at least one of the luminance, contrast, and γ correction value edge enhancement degree of the image indicating the advertisement information is changed over time. Change. Thus, the user's attention can be alerted by changing the image indicating the advertisement information.

  The second method is a method of changing at least one of the size, the display position, and the image content of the image indicating the advertisement information over time. The CPU 8 controls the image processing unit 9 while displaying an image indicating the advertisement information, and changes at least one of the size, display position, and image content indicating the advertisement information with time. For example, as shown in FIGS. 6A and 6B, the size of the image (i5) indicating the advertisement information may be changed. Further, as shown in FIG. 6C, the display position of the image (i6) indicating the advertisement information may be changed. In addition, when changing a display position, in order to prevent image sickness, it is good to carry out a left-right symmetrical motion in the left-right symmetrical position. Further, as shown in FIG. 7A, the image (i7) indicating the advertisement information is started from the center of the screen and is advanced to the vicinity of the outer periphery of the screen, and thereafter, the movement of making one round of the peripheral edge of the screen is repeated. Anyway. Thereby, a user can be made to recognize reliably the image (i7) which shows advertisement information. Further, as shown in FIGS. 7B and 7C, the image content of the image (i8) indicating the advertisement information may be changed. Thus, the user's attention can be alerted by changing the image indicating the advertisement information. This method is particularly effective when a still screen is displayed.

Note that the first method and the second method described above may be executed in combination.

A monocular head-mounted display has a feature that an image is displayed on one eye, and when a strongly stimulating (bright, complicated, etc.) scene is presented to an eye that does not display an image, the displayed image is difficult to see. As described above, when the user gives an instruction via the operation unit 4 at a timing at which the displayed image is difficult to see, the advertisement is displayed, and the advertisement information is effectively displayed while returning the user's attention to the display unit. can do.

In addition, according to the present embodiment, the image indicating the advertisement information is displayed for a certain period of time, and the brightness, contrast, γ correction value, and edge enhancement degree of the image indicating the advertisement information are displayed while the image indicating the advertisement information is displayed. At least one is changed over time. Therefore, the video stimulus of the image indicating the advertisement information can be strengthened, and the user's attention can be drawn toward the advertisement information.
Further, according to the present embodiment, the image indicating the advertisement information is displayed for a certain period of time, and at least one of the size, the display position, and the image content indicating the advertisement information is displayed while the image indicating the advertisement information is displayed. Is changed over time. Therefore, by such a change, the user's attention can be returned to the display unit, and attention can be directed toward the advertisement information.

Moreover, according to this embodiment, a moving image is displayed as an image which shows advertisement information. Therefore, the user's attention can be alerted to the advertisement information by the motion of the moving image.
Moreover, according to this embodiment, the holding | maintenance part which acquires and hold | maintains advertisement information previously is further provided. Therefore, a large-scale facility such as a broadcasting station necessary for acquiring advertisement information on the go is unnecessary. Therefore, it is possible to provide advertisement information to the user while suppressing the equipment cost.

  Further, according to the present embodiment, the advertisement information is acquired in association with the timing signal indicating the timing for displaying the advertisement information. Therefore, by displaying the advertisement information according to the timing signal, the advertisement information can be provided to the user at an effective timing.

Therefore, advertisement information can be displayed at a more accurate timing.
In addition, according to the present embodiment, the information processing apparatus further includes an acquisition unit that acquires a plurality of advertisement information in association with selection information for selecting advertisement information to be displayed on the display unit from the plurality of advertisement information. Therefore, since a plurality of advertisement information can be provided collectively, no large-scale equipment is required. Moreover, it is possible to select appropriate advertisement information from among a plurality of advertisement information and provide it to the user.

In addition, it is good also as a structure which acquires advertisement information and a timing signal with the method and timing other than having demonstrated in this embodiment.
Moreover, it is good also as a structure which displays advertisement information, when a user's attention deviates from a display part using a gaze recognition technique.
Moreover, it is good also as a structure which determines the timing which displays advertisement information in consideration of the information which shows the use position of HMD100 acquired by GPS etc., and the information which shows the position of an access point in the timing signal in this embodiment.

  In the present embodiment, an example is shown in which an image indicating advertisement information is displayed at a timing based on a user instruction or at a timing based on a timing signal. However, the CPU 8 prefetches the image information of the media player unit 3 and the user The image indicating the advertisement information may be displayed at a timing when an image that cannot concentrate on the screen is displayed. In general, the user cannot concentrate on the screen easily when the display image is an image with a low contrast or a small pattern. Therefore, the user can concentrate on the screen by pre-loading the image ahead of the current display point and displaying the image indicating the advertisement information at the timing when the image is displayed so that the user cannot concentrate on the screen. The advertising information can be effectively provided while alerting the user at the timing of disappearance. Whether the display image is an image having a low contrast or a small pattern can be known by examining the frequency distribution of luminance of the screen, the frequency distribution of chromaticity, the spatial frequency distribution of the image, and the like.
