Problems solved by technology

[0009] However, in the technologies described in patent documents from Patent Document 1 to Patent Document 4, when the movement amount such as the speed and acceleration of the subject is large, it may not be possible to automatically track the subject and cannot to shoot
In addition, the user of the video camera that photographs the subject needs to check the viewfinder and the monitor to confirm whether the photograph is taken normally, and there is room for improvement in the photographing method for visually confirming the subject and photographing the subject normally
In addition, in the video camera, the external scene visually recognized by the user of the video camera may differ from the external scene captured by the video camera.
In addition, there is a problem of determining the position of the subject without photographing the subject

[0060] figure 1 It is an explanatory diagram showing a schematic configuration of the imaging system 1000 in the embodiment of the present invention. exist figure 1 In the photographing system shown, in a sporting event, a user US of a head-mounted display device 100 (details will be described later) performs an inspection on an object OB wearing an object position determining device 500 for determining the position of the object OB. shoot. The imaging system 1000 includes a subject position specifying device 500 and a head-mounted display device 100 . The subject position determining device 500 is formed in a hat worn on the head of the subject OB...

Deformed example 1

[0130] In the above embodiment, if Figure 12 As shown, the bird's-eye view VI1 and the captured image VI2 are displayed in the lower right area when the largest image display area PN is divided into nine equal parts. out of shape. Figure 13 It is an explanatory diagram showing an example of the field of view VR visually recognized by the user US. exist Figure 13 , and the above embodiment in the Figure 12 The illustrated diagrams are different in that the position where the captured image VI2 is displayed in the largest image display area PN is different. In the head-mounted display device 100 of this modified example, the control unit 10 sets the position where the captured image VI2 is displayed in the largest image display area PN to A position not overlapping the subject OB is set in the largest image display area PN. Therefore, in the head-mounted display device 100 of this modified example, the user US can always visually recognize the subject OB of the external...

Deformed example 2

[0134] In the above-described embodiment, the image showing the position of the object OB displayed in the largest image display area PN and the position of the image in the largest image display area PN are changed based on the relative position of the object OB with respect to the user US. , but the image and the position where the image is displayed are not limited to this, and various modifications can be made. Figure 14 It is an explanatory diagram showing an example of the field of view VR visually recognized by the user US. Such as Figure 14 As shown, in a portion including the center of the largest image display area PN, an arrow MK4 as an image indicating the position of the object OB is displayed. exist Figure 14 , the field of view VR of the user US does not include the subject OB, and the arrow MK4 indicates that the subject OB is located on the right side of the user US. In the head-mounted display device 100 of this modified example, when the subject OB is ...

Abstract

A transmission type head mounted display includes an image display unit that forms an image on the basis of image data and allows the formed image to be visually recognized by a user as a virtual image in a state in which the image display unit is mounted on the head of the user, a position specifying unit that specifies a target position which is a position of a specific target object relative to the image display unit; and a control unit that causes the image display unit to form a target position display image indicating the target position and that sets a position of the target position display image in an image formation region which is a region where the image display unit forms an image, on the basis of the target position specified by the position specifying unit.

Description

technical field [0001] The present invention relates to a head-mounted display device. Background technique [0002] A head-mounted display device (Head Mounted Display, HMD) is known as a display device worn on the head. A head-mounted display device, for example, uses a liquid crystal display and a light source to generate image light representing an image, and uses a projection optical system and a light guide plate to guide the generated image light to the user's eyes, allowing the user to visually recognize a virtual image. There are two types of head-mounted display devices: a transmissive type in which a user can visually recognize an external scene in addition to a virtual image, and a non-transmissive type in which a user cannot visually recognize an external scene. Transmissive head-mounted display devices include an optical transmissive type and a video transmissive type. [0003] On the other hand, it is known to receive a signal transmitted from a transmitter ...
