When the camera unit 100 is taking an image, the image captured by the camera unit 100 is displayed at the corner of the field of view. When the image is displayed on the display unit D3 provided during the shooting, the display of the image does not become a hindrance during shooting, and a large image can be displayed during the reproduction of the image, which is convenient.

[Third Embodiment] FIG. 8 is a perspective view of an image recording apparatus according to a third embodiment of the present invention.
Referring to the figure, the image recording apparatus of the present embodiment is different from that of the second embodiment in that
0 is provided with two cameras 100R and 100L corresponding to the left and right eyeballs of the photographer, respectively. The eye-gaze detecting sensors 401R and 401L and the crystalline lens detecting sensor 4 correspond to the left and right eyes of the photographer.
03R and 403L are provided. Thereby, the corresponding cameras 100R and 100L can be controlled according to the detection results of the left and right eyeball states.

FIG. 9 is a diagram for explaining a control method of the image recording apparatus according to the third embodiment.

Referring to the figure, the line-of-sight detection sensors 401R,
An eyeball sensor including the lens 401L and the lens detection sensors 403R and 403L detects a line-of-sight direction of both eyes of the photographer and a change in the lens. Cameras 100R and 100L are 1
A pair of cameras, which enable zoom control, focus adjustment control, and change in the optical axis direction, respectively.

The control unit 405 also controls the left and right cameras 100R, 100R according to the state of the left and right eyeballs ER, EL.
00L can be controlled independently. Further, two recording units are provided corresponding to the left and right cameras 100R and 100L, respectively, and independently store the images of the left and right cameras.

In the example of FIG. 9, two recording units 409 are provided.
R and 409L are recorded with the respective images of the left and right cameras. However, as shown in FIG.
11, the control of the left and right cameras 100R and 100L and the recording of images may be performed.

When calculating the distance to the object to which the eyeball is focused by detecting the thickness of the crystalline lens, calibration is performed for each photographer,
It is desirable to memorize the thickness of the crystalline lens.

For example, a calibration image to be formed 2 m ahead is displayed on the displays D1 and D2 shown in FIGS. Then, the image is watched by the photographer, and the thickness of the crystalline lens in that state is measured. next,
Measure the thickness of the crystalline lens when the photographer is looking at a distant view.

Using the measurement results of the thickness of the crystalline lens at these two points, the relationship between the thickness of the crystalline lens and the distance to the target object to which the eyeball is focused can be obtained and used for focus adjustment and zoom control.

If the state of both eyes is measured by an imaging device as shown in FIGS. 8 to 10, the convergence angle, which is the angle at which a straight line extending the optical axis (the line of sight) of both eyes intersects, is used. It is also possible to determine the distance to the object on which the eyeball is focused.

FIGS. 11 to 15 are diagrams for explaining a process for obtaining the convergence angle θ. The convergence angle θ is calculated based on the gaze directions of both eyes. The line of sight is, for example, disclosed in JP-A-61-172552 and Japanese Patent No. 289470.
No. 1 can be detected.

In order to detect the line of sight, calibration is required for each user. Therefore, it is desirable to store gaze data for each photographer before photographing. In this method, an image is projected on a display as described above, and the photographer is gazed at the image, thereby performing calibration input and setting.

FIG. 11 is a diagram showing the relationship between the left eyeball EL, the right eyeball ER, and the convergence angle θ when the photographer is looking at an object at a distance L in the front direction.

FIG. 12 shows a state in which the photographer is looking at an object at an infinite distance in the front direction, and FIG. 13 shows a state in which the photographer is looking at an object at an infinite distance in the left direction. It is a figure showing a state at the time. When the convergence angle θ is large, it is understood that the target is near, and when the angle is small, it is far.

As shown in FIG. 14, the left eyeball E
Assuming that the angle between the front direction FL of L and the line of sight of the left eyeball EL is θ1, and the angle between the front direction FR of the right eyeball ER and the line of sight of the right eyeball ER is θ2, the convergence angle θ is θ =
θ1 + θ2 (when the object is between the front direction FL of the left eyeball EL and the front direction FR of the right eyeball ER).

Further, as shown in FIG. 15, when the object is on the left side of the front direction FL of the left eyeball EL, the convergence angle θ can be represented by θ = | θ1−θ2 |.

The direction of the object can be known from the relationship (sign or absolute value) between θ1 and θ2 described above. In addition, in FIGS. 11 to 15, an example in which the object is in the plane direction is described. However, when the object is in the vertical direction and in the oblique direction, the direction of the target object is similarly known. Can be.

Assuming that the width between the left eyeball EL and the right eyeball ER is d, the distance L to the focused object is L = d / (tan (θ1) + tan (θ2)) (θ
When the signs of 1 and θ2 are opposite; FIG. 14) L = d / | tan (θ1) −tan (θ2) | (θ
When the signs of 1 and θ2 are the same;

That is, if θ1 ≒ θ2, the photographer is looking at the target object at infinity.

The control in the optical axis direction of the camera may be performed as follows. That is, the optical axis direction (shooting direction) of the camera is changed depending on the line of sight. For example, when the user looks rightward, if the state is continued for a predetermined time, the camera is panned rightward, It stops when it is moved in the line of sight.

Further, when the line of sight returns to the front, the camera may be stopped in the right direction without panning, or may be returned to the front. Switching control may be performed so that the user can select one of the modes.

That is, in order for the user to record an image on the right while facing the front, the user first gazes at the right, pans the camera to the right, and stops and fixes the camera. here,
It is also possible to perform a camera operation such as starting image recording triggered by stopping.

The distance to the object may be estimated and calculated by combining the information on the convergence angle and the information on the crystalline lens.

In the above-described embodiment, zooming and panning of the camera can be performed without the user manually operating the camera. For example, when photographing is started, the focal length of the lens is set to an initial position (for example, a side close to wide), detection of the line of sight is started, and the line of sight stops in a specific direction for a predetermined time (T1) It is determined that the user is gazing at an object in that direction, and the focal length can be changed to the telephoto side (zoom up).

At this time, the convergence angle θ is calculated, and the zoom-in may be performed only when θ is smaller than a predetermined value (when the object is at a long distance). Further, a mode may be provided for switching between the necessity / unnecessity of zooming depending on the magnitude of θ.

When the line of sight moves in a direction other than the photographing direction of the camera (horizontal direction or vertical direction), the focal length of the camera is moved to the wide side to capture the subject in the direction in which the user wants to photograph. The gaze direction also changes at this time,
If the gaze time in that direction has passed a predetermined time (T2), the focal length is zoomed out to the wide side. However, in order to reduce the time for the object to be taken to disappear from the angle of view of the camera, a predetermined time (T
It is desirable to make T2 shorter than 1) (that is, T2).
2 <T1).

The eyeball may move finely regardless of the photographer's intention. Therefore, it is desirable to give a certain allowance to the movement of the line of sight, ignore the movement of the fine eyeball, and judge that the user is gazing at the object in the line of sight even with the movement of the fine eyeball. . That is, when the movement of the eyeball does not exceed the predetermined range, it is determined to be the gaze state.

Immediately after the camera starts zooming up, the camera may continue to move the focal length toward the target position even if the line of sight moves, and may continue shooting until the movement of the focal length ends. In this way, it is possible to capture an image while the photographer is not looking while the focal length is moving, and to confirm the photographed image later. That is, the zoom-up is executed following one gaze, but after the execution, the function may be released. Further, such a function may be made selectable by the user.

Is desirably displayed as follows.

FIG. 16 is a diagram for explaining a display at the time of photographing an image.

In addition,
The display units D1 and D2 are light transmission type displays.

As shown in FIG. 16, when the photographer is looking at the object to be photographed through the display units D1 and D2, the visual axis detection sensor 401 and the crystalline lens detection sensor 403 adjust the camera unit 100 according to the movement of the visual axis. To change the direction. Further, focus adjustment and zoom control are also performed according to the state of the eyeball E.

As shown in FIG. 17, when it is detected that the photographer gazes at the display unit D3, the rotation of the camera unit 100 is stopped, and the photographer watches the display unit D3 before looking at the display unit D3. Control is performed so that images in the directions are recorded.

That is, when the display unit D3 is gazing, change of the focal length, change of the optical axis direction of the lens, and zoom control by detecting the state of the eyeball are prohibited. Accordingly, the photographer can view the photographed image on the display unit D3 while fixing the photographing direction and the like to the photographing target.

It is desirable to determine whether or not the user is gazing based on the results of detection of both the direction of the line of sight and the change in the thickness of the crystalline lens.
