Description

  The present invention relates to an imaging device, and more particularly to an imaging device capable of cooperating with a wearable device.

  An imaging device or system having two imaging units is already popular and is a general technique. Specifically, there are various cases in an imaging apparatus having two imaging units, such as a system that shoots by linking a plurality of cameras and an imaging apparatus that has two lenses for capturing a stereoscopic image. . Furthermore, there is a technique for extracting the same angle of view from two images acquired from two imaging units when there are two imaging units as described above.

  Patent Document 1 discloses a method for acquiring a right-eye image and a left-eye image and adjusting the angle of view from each image in a camera that captures a stereoscopic image.

International Publication No. 2013/099169

  However, there are scenes in which the angle-of-view extraction method proposed in Patent Document 1 is insufficient. Specifically, if you want to take a picture with the camera according to the composition captured by the wearable device, you need to always follow the angle of view at the stage before shooting, not just aligning the angle of view with the captured image. There is.

  However, since the same angle of view can only be extracted from the captured image only by the method of extracting the angle of view in Patent Document 1, the angle of view cannot always be tracked at the stage before the image capture. If it cannot be obtained, it is impossible to obtain an image that matches the wearable angle of view.

  Therefore, the object of the present invention is to connect the wearable device and always follow the angle of view of the wearable device from the stage before photographing when the photographer wants to take a picture according to the composition taken by the wearable device. An object of the present invention is to provide an imaging apparatus having a function of photographing at the same angle of view as the angle of view.

In order to achieve the above object, an imaging apparatus according to the present invention includes:
An imaging unit that forms a first image, an image acquisition unit that communicates with a wearable device to acquire a second image, and compares the angles of view of the first image and the second image and satisfies a predetermined condition An angle-of-view comparing means for determining whether or not the angle of view is determined by the angle of view determining means, an angle of view adjusting means for adjusting the angle of view so as to satisfy the condition, a means for receiving a shooting instruction from the wearable device, When receiving a shooting instruction, an image estimated to have the same angle of view as the second image is extracted from the first image and stored.

  According to the present invention, when a photograph is taken with a camera according to the composition taken by the wearable device, the wearable device is connected to the wearable device so that it always follows the angle of view of the wearable device from the stage before shooting. It is possible to provide an imaging device having a function of shooting at the same angle of view.

<First embodiment>
Hereinafter, the control flow of the imaging apparatus according to the first embodiment of the present invention will be described with reference to FIG.

  In S201, a first image captured by the imaging lens 100 of the imaging apparatus is formed.

  In S202, the communication member 108 is used to communicate with the wearable device, and the second image captured by the photographic lens 114 of the wearable device is received from the wearable device.

  In S203, the image processing unit 107 compares the composition of the first image and the second image.

  In S204, it is determined from the comparison result in S203 whether or not a condition established in advance is satisfied. For example, the determination is made based on conditions such as whether the composition of the first image is larger than the composition of the second image or whether the composition of the first image is twice that of the second image.

  If the condition is not satisfied as a result of the determination in S204, the lens control unit 109 controls the photographing lens 100 to adjust the angle of view until the condition is satisfied in S205. For example, when the composition of the first image is smaller than the composition of the second image, the lens control unit 109 controls to zoom out to the photographing lens 100. Further, the composition may be adjusted by controlling the lens of the wearable device instead of controlling the lens of the imaging device. Until the shooting instruction is received from the wearable device, the processing from S202 to S205 is repeatedly executed.

  When a shooting instruction is received from the wearable device in S206, in S207, the image processing unit 107 extracts an image estimated to have the same angle of view as the angle of view of the second image from the first image.

  In S208, the extracted image is stored in the recording medium 116.

  Although it is assumed that an image formed with a wearable device has a lower image quality than an image formed with an imaging device such as a single-lens reflex camera, according to the present invention, an image is recorded following the angle of view of the wearable device. As a result, it is possible to store a high-quality image formed by a single-lens reflex camera with a composition captured by a glasses-type wearable device.

<Second embodiment>
Hereinafter, with reference to FIG. 3, control for adjusting the composition in preference to the wearable composition according to the second embodiment of the present invention will be described.

  S301 to S303 are the same controls as S201 to S203.

  In S304, it is determined from the comparison result in S303 whether or not a condition set in advance is satisfied. For example, the determination is made based on whether or not the composition of the first image is twice that of the second image.

  As a result of the determination in S304, if the condition is not satisfied, in S305, the lens control unit 109 controls the photographing lens 100 to adjust the angle of view.

  In S306, it is determined whether the condition is satisfied as a result of adjusting the angle of view in S305.

  If the result condition determined in S306 is not satisfied, in S307, the wearable device is instructed to change the zoom magnification.

  A specific example will be described in more detail using the conceptual diagram of FIG.

  FIG. 5 schematically illustrates the composition of the first image acquired by the imaging apparatus and the composition of the second image acquired by the wearable device.

  If the composition of the first image is larger than the composition of the second image and the composition is more than twice the condition as shown in FIG. 5A, the image pickup apparatus side is zoomed in as much as possible. The composition is reduced to a state as shown in FIG. However, if the condition of double the second image cannot be satisfied even if the zoom limit on the imaging device side is controlled, the zoom-out instruction is given to the wearable device side to enlarge the composition of the second image. 5- (c) is set.

  In this manner, the angle of view is adjusted by controlling the lens on the imaging device side as much as possible, and the zoom instruction is given to the wearable device only when the angle of view cannot be adjusted due to the performance of the lens on the imaging device side. S308 to S310 are the same controls as S206 to S208.

  In the first embodiment, the angle of view is adjusted by controlling the lens of the imaging device and the lens of the wearable device. However, according to the present invention, by controlling the lens of the imaging device as much as possible as described above, You can make adjustments without changing the composition of the wearable device as much as possible. Therefore, it becomes possible to take a picture of the composition as it is viewed by the user with a glasses-type wearable or the like.

<Third embodiment>
Hereinafter, control for adjusting a composition when the composition captured by the wearable device cannot be imaged by the imaging apparatus according to the third embodiment of the present invention will be described with reference to FIG.

  S401 to S403 are the same controls as S201 to S203.

  In S404, it is determined whether an image having the same angle of view as the second image exists in the first image. If it does not exist in S404, the angle of view is adjusted by the lens control unit 109 until the same angle of view exists. In addition to the angle of view of the first image and the second image, if the subject being imaged by the wearable device has not been acquired by the imaging device, the angle of view captured by the imaging device by controlling the imaging lens 100 To find the same angle of view.

  A specific example will be described with reference to the conceptual diagram of FIG.

  FIG. 6 schematically illustrates the composition of the first image acquired by the imaging apparatus and the composition of the second image acquired by the wearable device.

  FIG. 6A schematically shows a state where the angle of view of the second image is not included in the angle of view of the first image. In such a state, by zooming out the imaging device side, the composition is expanded until the same angle of view as the second image exists within the angle of view of the first image. Make it like this.

  In this way, the angle of view is adjusted so that the angle of view of the second image is included within the angle of view of the first image. This flow describes the control of adjusting the angle of view until it exists, but if the same angle of view is not found even if the photographic lens 100 of the imaging device or the photographic lens of the wearable device is controlled, the adjustment of the angle of view is performed. The control may be terminated and a warning display may be given to the user. S406 to S408 are the same controls as S206 to S208.

  According to the present invention, even when the composition captured by the wearable device cannot be captured by the imaging device, the composition is adjusted, and the composition as seen by the user captured by the glasses-type wearable is captured. Is possible.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment, A various deformation | transformation and change are possible within the range of the summary.
