Rear view of an imaging apparatus having a main body and a display and connected by an opening / closing part and a turning part Side view when the imaging device of FIG. 3 is viewed from the left side 3 is a rear view of the imaging apparatus having a displacement device that deforms a specific region of the surface on the display unit in the imaging apparatus of FIG. 3. 5 is a side view of the image pickup apparatus of FIG. 5 when viewed from the left side.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a rear view of the image pickup apparatus 100 according to the first embodiment of the present invention when viewed from the image pickup element side. FIG. 2 is a top view of the imaging apparatus 100 in FIG. 1 as viewed from above when the display unit is opened at a certain angle. FIG. 3 is a rear view of the image pickup apparatus 100 according to the second embodiment when viewed from the image pickup element side. FIG. 4 shows a side view of the imaging device 100 in FIG. 3 when viewed from the left side. FIG. 5 is a rear view of the imaging apparatus 100 according to the third embodiment when viewed from the imaging element side. FIG. 6 shows a side view of the imaging device 100 in FIG. 5 when viewed from the left side.

  The first embodiment will be described with reference to FIGS. The imaging apparatus 100 includes a main body (fixed part) 1, a display unit 2, and a lens unit 7. The imaging apparatus 100 described this time will be described by exemplifying a lens interchangeable digital single-lens reflex camera as an example of an electronic apparatus. Although not shown, the main body 1 has a user operation unit such as a command dial or a switch. The display unit 2 has a display surface 20 and has a display function for displaying various icons 5 on the display surface 20. Further, the display unit 2 has a touch panel function for realizing a user's touch operation via the display surface 20. The touch panel is, for example, a liquid crystal display (LCD), and includes a touch detection unit that detects a user's touch position and a sensitivity adjustment unit that adjusts (changes) the touch sensitivity (detection sensitivity) on the display surface 20. (Sensitivity change unit). The display unit 2 is connected to the main body unit 1 through the opening / closing unit 3. The opening / closing section (first connecting section) 3 connects (connects) the display section 2 to the main body section 1 so that the angle can be varied about the opening / closing axis (first rotating shaft) 30. The open / close unit 3 is provided with a state detection unit that detects the open / close state of the display unit 2.

  As shown in FIG. 2, when the user touches the display surface 20 in a state where the display unit 2 is opened at an angle (open state), T is the torque of the opening / closing unit 3 around the opening / closing shaft 30. It is represented by

ここで、Ｆは表示面２０に垂直な方向のユーザの力、ｘは開閉軸３０を基準としてユーザがタッチした位置（開閉軸からの距離）である。

Here, F is a user's force in a direction perpendicular to the display surface 20, and x is a position touched by the user with respect to the opening / closing axis 30 (distance from the opening / closing axis).

  Since the torque required for the opening / closing part 3 to start rotating around the opening / closing shaft 30 is constant, the smaller the distance from the opening / closing shaft 30 is touched (the more it goes to the arrow 32 in FIG. 1), the smaller the torque is. Due to the force, the display unit 2 rotates about the opening / closing shaft 30, which is difficult to operate. Therefore, in the first embodiment, when it is detected that the display unit 2 is opened by the state detection unit, the sensitivity adjustment unit displays the display surface according to the touch position on the display surface 20 detected by the touch detection unit. The touch sensitivity of 20 is changed. At this time, the touch sensitivity is increased as the distance from the opening / closing axis 30 on the display surface 20 is larger (as the arrow 32 is approached). As a result, when a location away from the opening / closing axis 30 on the display surface 20 is touched, the icon 5 on the display surface 20 reacts with a smaller force, making it difficult to rotate the display unit 2 around the opening / closing axis 30. Thus, the operability of the imaging device 100 can be improved. The state detection unit detects whether or not the display unit 2 is closed at the storage position of the main body unit 1. When the display unit 2 is in the open state, the sensitivity adjustment unit performs the touch sensitivity described above. Control to change according to the position of the screen. When the display unit 2 is in the closed state, even if the display surface 20 is pressed in this state, the display unit 2 does not rotate. Therefore, it is necessary to perform the above control for the purpose of suppressing the unexpected rotation. Absent. In addition, even when the display unit 2 is open, when the opening / closing unit 3 includes a mechanism that can be fixed at a predetermined opening degree, the touch according to the present invention can be used even in the fixed state. It is not necessary to control the change in sensitivity.

  A second embodiment of the present invention will be described with reference to FIGS. The imaging device 100 in FIG. 3 is rotated so that the display unit 2 can be rotated not only by the opening / closing unit 3 but also as indicated by an arrow 43 in FIG. 4 with respect to the imaging device 100 in FIG. Part (second connecting part) 4. Here, as shown in FIG. 3, the coordinates on the display surface 20 are the rotation axis (second rotation axis) 40 as the x axis and the opening / closing axis (first rotation axis) 30 as the y axis. Consider the relationship between torque and force when the user touches the display surface 20. In the display unit 2 of the present embodiment, the directions in which the rotation is allowed are limited to the rotation about the opening / closing shaft 30 and the rotation about the rotation shaft 40. Therefore, whether or not the rotation about the opening / closing axis 30 and the rotation axis 40 occurs when the user touches the display surface 20 can be evaluated independently. The distance from the rotation axis 40 on the display surface 20 touched by the user is X, the distance from the opening / closing axis 30 is Y, and the component perpendicular to the display surface 20 of the force touched by the user on the display surface 20 is F. And The torque Ty centered on the opening / closing axis (y-axis) 30 and the torque Tx centered on the rotation axis (x-axis) 40 by pressing (touching) the display surface 20 of the user are expressed as follows.

Ty = F × X
Tx = F × Y
When the torque Ty is larger than the torque Ty_min required for the opening / closing portion 3 to start rotating about the opening / closing shaft 30, the opening / closing portion 3 rotates about the opening / closing shaft 30. When the torque Tx is larger than the torque Tx_min necessary for the opening / closing unit 3 to start rotating around the rotation shaft 40, the opening / closing unit 3 rotates about the rotation shaft 40.

  When the user touches the display surface 20, the display unit 2 opens and closes with a smaller force as the distance from the opening / closing shaft 30 and the rotation shaft 40 at the pressing position increases (towards the arrow 32 and the arrow 42). It rotates around the axis 30 or the rotation axis 40. Therefore, in the second embodiment, when the open / close state of the display unit 2 is detected by the state detection unit and the display unit is not in the closed state, the sensitivity is determined according to the touch position on the display surface 20 detected by the touch detection unit. The touch sensitivity of the display surface 20 is changed by the adjustment unit 8. At that time, the touch sensitivity is increased as the distance from the opening / closing shaft 30 or the rotation shaft 40 on the display surface 20 is larger (as the arrow 32 or the arrow 42 is approached). That is, the touch sensor recognizes the input before a force that starts to rotate around the opening / closing axis or the rotation axis is applied to the display surface 20. In the present embodiment, the opening / closing part 3 can rotate around the opening / closing axis 30 and rotate around the rotation axis 40. The torque necessary for the opening / closing section 3 to start rotating is Ty_min for rotation about the opening / closing axis 30 and Tx_min for rotation about the rotation axis 40. That is, if the touch sensitivity that the display unit does not rotate due to the force at the time of touch input is calculated at each position with respect to the rotation in each direction, the greater sensitivity is set as the touch sensitivity for that position Any rotation can be avoided.

  Thereby, when the place away from the opening / closing axis 30 or the rotation axis 40 on the display surface 20 is touched, the icon 5 on the display surface 20 reacts with a smaller force, and the display unit 2 becomes difficult to drive. The operability of the imaging apparatus 100 is improved.

  In the first and second embodiments, application to a display unit that can rotate about one axis and two axes has been illustrated, but the present invention is not limited to this, and the display can be rotated about three axes. The same applies to the part.

  A third embodiment of the present invention will be described with reference to FIGS. In the third embodiment, a displacement device 6 in which a specific area on the surface is deformed is configured on the display surface 20 of the display unit 2. The displacement device 6 is disposed substantially in parallel so as to cover the display surface 20. Then, based on a command from a system control unit (not shown), the internal cavity is expanded, and the specific area of the display surface 20 is deformed into a convex shape as shown in FIG. By using such a displacement device, in the touch display, it is possible to improve visibility and to improve user operability by providing a click feeling. However, this technique forms a convex shape on the display surface 20 and gives a tactile click feeling to the user by pressing the convex shape, so compared with a normal touch display without a displacement device. A strong pressing force is required. Therefore, in the case of touch input, a display part becomes easier to rotate than the case of the normal touch display which is not provided with a displacement device. From this, by applying the sensitivity adjustment technique of the present invention, the display unit 2 is more driven by the pressing force when trying to press the portion where the separation distance of the opening / closing shaft 30 or the rotating shaft 40 is large. It can be effectively prevented.

  In this embodiment, the image pickup apparatus has been described as an example.
