Description

  The present invention relates to an imaging device, and more particularly to touch panel control technology.

  Among recent imaging devices, there is one in which a display device provided with a touch panel is connected to a main body of the imaging device by a hinge mechanism. By connecting the imaging device and the display device by a hinge mechanism, the photographer can change the position of the display device with respect to the imaging device, and imaging in various postures is possible.

  For example, when the photographer holds the imaging device by hand and captures the appearance of the photographer, the display screen is turned by turning the display device to a position facing the photographer. It is possible to shoot while displaying the photographer himself.

  Furthermore, the display device is equipped with a touch panel, which facilitates change of shooting conditions and the like by touch panel operation. When it is desired to focus on an intended position in the display screen, the photographer can focus on the subject simply by touching the intended position on the display screen with a fingertip. For example, when the photographer photographs the photographer himself, focusing can be performed on the photographer's face simply by touching the photographer's face displayed on the display screen with a finger.

  However, in a display device equipped with a touch panel, when the photographer performs a touch operation in a state where the display device is rotated to a position facing the photographer, the display device moves from the position, and the operability is not good. It was difficult to focus on the desired subject.

  As a solution to the above problem, Patent Document 1 discloses a configuration in which the operation sensitivity of the touch panel is increased to such an extent that the imaging device does not move, and blurring of a captured image due to touch panel operation at the time of moving image shooting is reduced.

JP 2014-75716 A

  However, in the case of an imaging device provided with a display device on the side as in Patent Document 1, shooting is performed while holding the display device with the left hand in order to prevent camera shake with the display device opened by rotating the display device 90 degrees. , There was a possibility of causing an incorrect operation. That is, if the sensitivity of the touch panel is increased, the touch is detected only when the hand approaches the touch panel, and an unintended touch operation is executed only by holding the display device, and the user's intended operation can not be performed. was there.

  As described above, when the vicinity of the touch panel is disposed at a position where the vicinity of the touch panel is held, the operability is better if the operation sensitivity of the touch panel is set low.

  On the other hand, when the display device is turned 180 degrees to take a self-shooting mode after the display device is open, the main body of the photographing device is gripped with one hand to take a distance from the face of the photographer Therefore, the vicinity of the display device is not gripped. Therefore, although the erroneous operation as described above does not occur, the display device is rotated by the touch operation, and the display device moves in the direction of escaping from the finger.

  That is, in the self-shooting state, it is important that the touch panel does not move due to the touch operation. For this purpose, the operability is improved by increasing the operation sensitivity so that the touch panel can be operated with a force not rotating.

  Therefore, an object of the present invention is to provide a comfortable imaging device that does not impair the operability of touch at any position regardless of the position of the touch panel in an imaging device provided with a rotatable touch panel.

In order to achieve the above object, an imaging device according to the present invention is
In an imaging apparatus provided with a rotatable touch panel, when the operation acceptance sensitivity of the touch panel is in the touch panel storage state and the rotation state, the rotational state has a higher operation acceptance sensitivity than the storage state, and the operation acceptance sensitivity in the touch panel is The operation acceptance sensitivity is higher as the distance from the motion axis is longer, and the operation acceptance sensitivity is set lower as the distance is shorter.

  Further, in the imaging apparatus including the rotatable touch panel, the rotation detection sensor for detecting the presence or absence of rotation, and the control unit for counting the number of rotations, changing the operation reception sensitivity according to the number of rotations It is characterized by

  According to the present invention, in an imaging device provided with a rotatable touch panel, it is possible to provide a comfortable imaging device that does not impair the touch operability at any position regardless of the position of the touch panel.

  Hereinafter, embodiments of the present invention will be described.

First Embodiment
Hereinafter, a camera according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 4. FIG. 1 is an external perspective view of a camera 100 according to the present embodiment.

  A display device 101 is provided on the back of the camera 100, and the main body of the camera 100 and the display device 101 are connected by a hinge mechanism (not shown). The display device 101 is rotatable with respect to the camera 100 about 0 to 180 degrees around the rotation axis of the hinge mechanism (not shown).

  FIG. 1A is a state diagram in which the display device 101 is accommodated, that is, a state in which the display device 101 is rotated by 0 degrees. FIG.1 (b) is the state figure which rotated the display apparatus 101 180 degree centering on the rotating shaft center of a hinge mechanism not shown.

  In photographing in the state of FIG. 1B, the photographer mainly captures the photographer himself. The photographer can set an intended composition while taking a look at the image displayed on the display device 101 and shoot.

  FIG. 2 is a three-sided view of the camera 100 in a state in which the display device 101 is accommodated.

  A display area (display unit) 201 is an area on the display device 101 for displaying image data, shooting conditions, and the like. The touch panel 202 is disposed on the display unit 201. In the present embodiment, the touch panel 202 is a capacitive touch panel, but may be a resistive touch panel or the like.

  The determination as to whether the touch panel 202 has been touch-operated is made by comparing the detection value output from the touch panel 202 with a predetermined threshold value in the control unit provided in the camera 100 main body. The control unit determines that the touch operation has been performed when the detected value exceeds the threshold. The sensitivity of the touch operation is determined by the threshold value, and setting the threshold value smaller increases the sensitivity, and setting the threshold value larger decreases the sensitivity.

  By raising the sensitivity of the touch operation, the touch operation can be performed simply by bringing the finger close to the touch panel 202 without directly touching the touch panel 202 with the finger. As described above, although the operability can be improved by increasing the sensitivity of the touch panel operation, there is a possibility of causing an erroneous operation. This content will be described with reference to FIG.

  It is assumed that the photographer grips the camera 100 with the right hand and shoots. At this time, the photographer holds the camera 100 by hand so as not to touch the touch panel 202 on the back.

  However, when the touch panel 202 occupies most of the area on the back surface of the camera 100 as in the present embodiment, there is a high possibility that the right hand may cover part of the touch panel 202. That is, the right hand is disposed at a position close to the touch panel 202.

  In the above state, if the sensitivity of the touch panel 202 is increased, there is a possibility that the camera 100 may determine that the touch operation has been performed, although the photographer has not performed the touch operation. The camera 100 executes an operation not intended by the photographer. That is, the photographer has made a mistake.

  From the above, it is convenient to not raise the sensitivity of the touch panel 202 when the display device 101 is in the storage state with respect to the camera 100.

  FIG. 3 is a three-sided view showing the relationship between the operability of the touch panel and the sensitivity when the display device 101 is rotated 180 degrees.

  The camera 100 is used in the state shown in FIG. 3 when the photographer photographs the photographer himself as described above, and at this time, the photographer holds the camera 100 with his left hand. The area that covers the camera 100 with the left hand is a grip area 301, and the touch panel 202 and the grip area 301 do not overlap as shown in FIG. That is, since the left hand of the photographer and the touch panel 202 do not approach each other, erroneous operation due to holding the camera 100 does not occur.

  However, when the photographer performs touch operation on the touch panel 202 in the state of FIG. 3, the display device 101 rotates from the state of the rotation angle 180 in the direction of the rotation angle 0 degree. That is, since the touch panel 202 moves in the direction away from the finger to perform the touch operation, there is a disadvantage that the photographer can not specify the intended location.

  Therefore, the details of the present embodiment will be described with reference to FIG. FIG. 4 is an external view of the camera 100 showing the contents of the present embodiment.

  In the touch panel 202, an area is divided into three in accordance with the distance from the rotation axis K of the hinge mechanism, and a threshold is set in each area. Regions L, M, and H are from the side closer to the rotation axis K, and the distances from the rotation axis K to the central portions of the respective regions are L1, L2, and L3, respectively. Assuming that the rotational moment generated on the assumption that the central portion of each region is stamped by the force of the load F is M1, M2, and M3, the following equation is given.

M1 = F · L1
M2 = F · L2
M3 = F · L3
From the relationship of L1 <L2 <L3, it is represented by the relational expression of M1 <M2 <M3.

  That is, since the display device 101 is rotated with a low load as the distance from the rotation axis K increases, it can be understood that the region H is the most difficult position to operate. Therefore, the present embodiment is characterized in that the threshold value of the touch operation in each area is changed in order to enable a good touch operation in the entire area without rotating the display device 101 by the touch operation. .

The threshold value of each region is set as the threshold value L, the threshold value M, and the threshold value H, and set in the following relational expressions.
Threshold L> Threshold M> Threshold H
As described above, since the sensitivity is higher as the threshold value is smaller, the sensitivity of the region H is set to the highest and the sensitivity of the region L is set to the lowest. From this, by changing the sensitivity according to the distance from the rotation axis K, a good touch operation can be made in all the regions without rotating the display device 101 by the touch operation.

  That is, as described above, in the imaging device provided with the rotatable touch panel, even in the structure in which the touch panel is pivoted by the touch operation, it is possible to provide the imaging device which can be touch-operated without impairing the operability.

Second Embodiment
Next, a camera according to a second embodiment of the present invention will be described. The first embodiment is the same as the first embodiment except that the sensitivity is changed according to the area of the touch panel 202. For this reason, duplicate explanations will be omitted, and differences will be described.

  Inside the camera 100 main body, a rotation detection sensor that determines whether the display device 101 is rotated 180 is provided. Moreover, the control part which counts the frequency | count N of rotation which the rotation sensor detected is provided.

  FIG. 5 is a graph showing the relationship between the rotational force F and the number of rotations N necessary to rotate the display device 101 connected by the main body of the camera 100 and the hinge mechanism (not shown).

  As shown in FIG. 5, the turning force F for turning the hinge mechanism normally decreases gradually by increasing the number of turns. That is, as the number N of times of rotation increases, the display device 101 can be rotated with a small rotational force F. In other words, the operation feeling of the touch operation is changed by the number of rotations N.

In the present embodiment, as shown in FIG. 5, when the number of rotations N is 0 to 2000, the threshold 1 is set, and for 2001 to 8000, the threshold 2 is set, and 8000 or more is set to the threshold 3. The relational expressions of thresholds 1, 2 and 3 are
Threshold 1> Threshold 2> Threshold 3 If replaced with the sensitivity, the sensitivity is increased according to the increase of the number of rotations N.

  In the present embodiment, as described above, the threshold value for determining the sensitivity is changed according to the number N of times of rotation. That is, as described above, it is possible to provide an imaging device which can perform touch operation without impairing operability, without changing the operation feeling according to the number of times of rotation of the display device 101.
