Description

  The present invention relates to an optical apparatus provided with a touch panel.

  Conventional interchangeable lenses cannot change the display position of switches such as a switch for auto focus (AF) and manual focus (MF), an ON / OFF switch for a camera shake correction mechanism, and a distance display. For this reason, the position of the handle may overlap with the switches and the display unit during vertical position shooting, and the operability may be impaired. Therefore, a lens having an operation unit that is easy to operate regardless of the holding state of the camera has been proposed.

  Patent Document 1 discloses that there is a sensor that detects contact along the circumferential direction of a lens, and a cover member that covers the outer surface of the sensor so as to be slidable and partially exposed is disclosed. When the posture is changed, the cover member is slid to change the exposure position of the sensor to a place where it can be easily operated, so that it can be operated easily regardless of the holding state of the camera.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a perspective view of an optical apparatus according to an embodiment of the present invention.

  FIG. 2 shows a lens 100 that is an optical apparatus of the present embodiment. Reference numeral 1 denotes a lens barrel, and a cylindrical touch panel 2 is disposed on the outer peripheral portion along the circumferential direction. FIG. 3 shows a configuration of the camera system of the lens 100 and the camera body 6 which is the optical apparatus of the present embodiment.

  Reference numeral 61 denotes a camera CPU constituted by a microcomputer. The camera CPU 61 controls the operation of each unit in the camera body 6. The camera CPU 61 communicates with the lens CPU 101 provided in the lens 100 via the electrical contacts 102 and 62 when the lens 100 is mounted. The information (signal) transmitted from the camera CPU 61 to the lens CPU 101 includes focus lens drive amount information, parallel shake information, and focus shake information.

  The information (signal) transmitted from the lens CPU 101 to the camera CPU 61 includes imaging magnification information. The electrical contacts 102 and 62 include contacts for supplying power from the camera body 6 to the lens 100.

  Reference numeral 64 denotes a release switch that can be operated by a photographer, and includes a first stroke switch SW1 and a second stroke switch SW2. A signal from the release switch 64 is input to the camera CPU 61. The camera CPU 61 enters a shooting preparation state in response to an ON signal input from the first stroke switch SW1. In the shooting preparation state, measurement of subject brightness by the photometry unit 65 and focus detection by the focus detection unit 66 are performed. The camera CPU 61 calculates the aperture value of the aperture unit 106, the exposure amount of the image sensor (shutter time), and the like based on the photometric result.

  The camera CPU 61 also obtains a focus state with respect to the subject based on focus information (defocus amount and defocus direction) that is a detection result of the focus state of the photographing optical system by the focus detection unit 66. Drive amount (including the drive direction) is determined. The information on the driving amount (focus lens driving amount information) is transmitted to the lens CPU 101.

  The lens CPU 101 controls the operation of each component of the lens 100. When an ON signal is input from the second stroke switch (SW2), the camera CPU 61 transmits an aperture drive command to the lens CPU 101, and causes the aperture unit 106 to set the previously calculated aperture value. In addition, the camera CPU 61 transmits an exposure start command to the exposure unit 67 to perform a retracting operation of a mirror (not shown) or an opening operation of a shutter (not shown), and the image of the subject image is detected by the imaging unit 68 including the imaging element. Conversion, that is, an exposure operation is performed. An imaging signal from the imaging unit 68 is converted into a digital signal by a signal processing unit in the camera CPU 61, and further subjected to various correction processes to be output as an image signal. The image signal (data) is recorded and stored in a recording medium such as a semiconductor memory such as a flash memory, a magnetic disk, or an optical disk in an image recording unit 69.

  Reference numeral 2 denotes a touch panel, which displays a lens information display unit 4 such as a focal length, switches such as an AF / MF switching switch, and a lens operation display unit 3 such as a zoom and a focus. The movement (slide) of the contact portion is detected.

  A zoom lens group 105 includes a plurality of lens groups, and the focal length is changed by moving in the optical axis direction. Reference numeral 109 denotes a zoom drive unit. The zoom drive unit 109 has a zoom motor, and receives a drive command from the lens CPU 101 that has received an operation on the touch panel 2 of the photographer to drive the zoom lens barrel. 100 focal lengths are changed.

  Reference numeral 106 denotes an aperture unit that drives aperture blades to adjust the amount of light. Reference numeral 110 denotes an aperture drive unit, which has an aperture motor, and is controlled by the lens CPU 101 that has received an aperture drive command from the camera CPU 61 and an operation of the photographer on the touch panel 2, thereby specifying the aperture unit 106. Operate in the open state corresponding to the value.

  Reference numeral 107 denotes a camera shake correction unit that performs an optical image stabilization function for correcting a so-called camera shake by moving the correction lens on a plane perpendicular to the optical axis. Reference numeral 111 denotes a camera shake correction unit drive unit, which includes a drive actuator of the camera shake correction unit 107 and its drive circuit. When the camera shake correction function is turned on, control of the correction lens shift drive of the camera shake correction unit 107, that is, the camera shake correction operation is started by a drive command from the camera CPU 61.

  A focus lens group 108 includes at least one lens, and performs focusing by moving in the optical axis direction. A focus driving unit 112 has a focus motor. Under the control of the focus lens drive amount information transmitted from the camera CPU 61 or the lens CPU 101 that has received an operation on the touch panel 2 of the photographer, the focus motor is driven to perform the focusing operation of the focus lens group 108.

  Reference numeral 113 denotes an angular velocity sensor mounted on the lens 100 and connected to a printed circuit board. The angular velocity sensor 113 outputs to the lens CPU 101 angular velocity signals indicating respective angular velocities of vertical (pitch direction) shake and lateral (yaw direction) shake, which are angular shakes of the camera system. The lens CPU 101 electrically or mechanically integrates the angular velocity signals in the pitch direction and the yaw direction from the angular velocity sensor 113, and the pitch direction shake amount and the yaw direction shake amount, which are displacement amounts in the respective directions (summarizing them). (Also referred to as angular deflection). Then, the lens CPU 101 controls the camera shake correction unit driving unit 111 based on the above-described combined displacement amount of the angle shake amount and the parallel shake amount to shift-drive the camera shake correction unit, thereby performing the angle shake correction and the parallel shake correction.

  The zoom operation unit 3a, the focus operation unit 3b, and the aperture operation unit 3c are displayed extending in the circumferential direction, and each operation unit is driven by sliding a finger in the circumferential direction. As shown in FIG. 3, “W” and “T” indicating WIDE and TELE are displayed on the zoom operation unit 3a. When the finger is slid in the “W” direction, the “T” is displayed on the wide angle side. When the finger is slid in the direction, the zoom lens barrel is driven to the telephoto side.

  “∞” and “0.7 m” representing the subject distance are displayed on the focus operation section. When you slide your finger in the direction of “∞”, your finger slides in the direction of “0.7 m” to the ∞ side. Then, the focus group is driven to the close side. (The display “0.7 m” indicating the closeness varies depending on the lens).

  The aperture operation part has an open Fno. And small aperture Fno. When the finger is slid in the direction of F4, the aperture is driven to the open side, and when the finger is slid in the direction of F32, the aperture is driven to the small aperture side (the displayed number varies depending on the lens).

  In this embodiment, a method of operating the lens by sliding the lens operation display unit 3 with a finger is shown. However, the lens operation may be performed by touching the lens operation display unit 3. For example, the zoom lens group 105 may be driven to the wide-angle side when “W” is touched and to the telephoto side when “T” is touched. In the present embodiment, the three types of operation units have been described. However, the operation unit may be a shutter speed or ISO sensitivity operation unit, and not limited to three types, there may be four types or five types of operation units. .

  In the present embodiment, the operation portion has an arc shape extending in the circumferential direction, but may be a ring shape or a shape extending in the optical axis direction, and is not particularly limited.

  The lens operation display unit 3 also has a switch unit such as an ON / OFF switch for an image stabilization function and an AF / MF switch, and the state of the image stabilization function and the focus state are displayed (in FIG. 4, the image stabilization function is ON, focus is MF). The state can be switched by touching the display unit. For example, when the camera shake correction function ON / OFF switch is touched from the state of FIG. 4, the camera shake correction function is turned off, and the display on the display unit is also changed to “IS OFF”. In addition to the switch section, there may be a photographing mode changeover switch such as an aperture priority mode “AV” and a shutter speed priority mode “TV”.

Reference numeral 4 denotes a lens information display unit that displays information on the lens state that is changed by operating the zoom operation unit 3 such as a focal length, a subject distance, and an aperture value. The display position of the display unit can be changed by operating the lens information display unit 4. Next, a method for changing the display position of the display unit will be described with reference to FIGS.

  When the power switch 63 of the camera 6 is pressed to activate the camera, the lens information display unit 3 and the lens operation display unit 4 are displayed on the touch panel 2 at preset default positions (step S1).

  Next, it is detected whether or not the lens information display unit 4 is touched (step S2). When the touch of the lens information display unit 4 is not detected (No in step S2), the display position of the display unit is not changed.

  When the touch of the lens information display unit 4 is detected (when Step S2 is Yes), the display position change mode of the display unit is set, and it is detected whether the lens information display unit 4 has been slid (Step S3). When it is detected that the lens information display unit 4 has been slid (Yes in step S3), the lens information display unit 4 and the lens operation display unit 3 change the display position according to the slide amount and the slide direction (step S4). . As shown in FIG. 1A, when the lens information display unit is slid in the circumferential direction, the display position changing unit 114 is a slide in which the entire display unit including the lens information display unit 4 and the lens operation display unit 3 is detected. Control to move in quantity and direction.

  When the slide of the lens information display unit 4 cannot be detected (No in step S3), it is detected whether the touch state of the lens information display unit 4 is maintained (step S11). When the touch state of the lens information display unit 4 is maintained (Yes in step S11), it is detected whether the lens operation display unit is slid (step S12). When the slide of the lens operation display unit 3 is not detected (No in step S12), the display position of the display unit is not changed. When the slide of the lens operation display unit 3 is detected (Yes in step S12), the display position of the slid lens operation display unit 3 is changed according to the slide amount and direction (step S13). As shown in FIG. 1B, when the lens operation display unit 3 is slid while pressing the lens information display unit 4, the lens operation display unit change mode is entered, and the display position change unit 114 detects only the lens operation display unit 3. Control is made to move in the slide amount and direction.

  When the touch state of the lens information display unit 4 is not maintained (when the finger is away) (No in step S11), the lens information display unit 4 is in a moving mode (step S21). It is detected whether or not the lens information display unit 4 is slid in the movement mode state of the lens information display unit 4 (S22). When the slide of the lens information display unit 4 is not detected (No in step S22), the display position of the display unit is not changed. When the slide of the lens information display unit 4 is detected (Yes in step S22), the display position changing unit 114 performs control to move only the lens information display unit 4 in the detected slide amount and direction (step S23). . As shown in FIG. 1C, once the lens information display unit 4 is touched, the lens information display unit moving mode is switched. At this time, the display of the lens information display unit 4 is changed to the lens information display unit movement mode, blinking, etc., to notify that the mode has been switched. When the lens information display unit 4 is again touched and slid in this state, the display position changing unit 114 performs control to move only the lens information display unit 4 in the detected slide amount and direction.

  If the power is turned off (Yes in step S5), the process ends. If power OFF is not detected (Yes in step S5), the process returns to the step (step S2) of detecting whether or not the lens information display unit 4 has been touched.

  As described above, the touch panel is arranged along the circumferential direction on the outer periphery of the lens barrel, and the display position of the display unit can be changed to a predetermined position by operating the lens information display unit. By doing so, the display unit can be changed to a position that is easy for the photographer to operate even if the photographer's holding state changes when the posture is changed, so that comfortable operability can always be maintained. .

  Although an example of the display position changing method by operating the lens information display unit 4 has been described above, the operation method of the lens information display unit 4 at the time of changing the display position is not particularly limited.

  Next, Example 2 will be described. In the second embodiment, the posture of the camera is determined, and the display position of the display unit is changed when the posture change is detected. FIG. 6 shows an electrical configuration of the camera system of the lens 200 and the camera body 260 which are the optical devices of the second embodiment. Only the parts different from the first embodiment will be described.

  Reference numeral 214 denotes an acceleration sensor mounted on the lens 200 and connected to a printed circuit board. The acceleration sensor 214 detects gravitational acceleration and outputs a gravitational acceleration signal to the posture determination unit 216. The posture determination unit 216 determines whether the camera is in a normal posture or a vertical posture from the gravitational acceleration signal. When the posture change is detected, the display positions of the lens operation display unit 23 and the lens information display unit 24 are automatically changed.

  The change of the display position of the display unit will be described with reference to FIGS.

  When the power switch 263 of the camera 260 is pressed to activate the camera, the posture determination unit 216 determines the posture of the camera. For example, when it is determined that the camera is in the normal posture, as shown in FIG. 8, the display position changing unit 215 performs control to move the lens information display unit 24 to the upper side opposite to the gravity direction (step S101).

  Next, it is detected whether or not the lens information display unit 24 is touched (step S102). When the touch of the lens information display unit 24 is not detected (No in step S102), the process proceeds to a step of detecting whether the posture of the camera is changed (step S105). When the posture change is not detected (No in Step S105), the display position of the display unit is not changed, and the process proceeds to a step of detecting whether the power is OFF (Step S107). If it is detected that the power has been turned off, the process ends. If power OFF is not detected, the process returns to step S102. When a change in the posture of the camera is detected (Yes in step S105), the display position of the lens information display unit is changed (step S106). For example, when the posture of the camera is changed to the vertical posture, the display position changing unit 215 performs control to move the lens information display unit 24 to the upper side opposite to the gravity direction as shown in FIG. The same 90 degree display position as the angle change from time to vertical posture is changed). After the change of the display position, the process after step S107 which moves to the step (step S107) for detecting whether or not the power is OFF is as described above.

  When the touch of the lens information display unit 24 is detected (when Step S102 is Yes), the display unit position change mode is set, and it is detected whether the lens information display unit 24 is slid (Step S103). When it is detected that the lens information display unit has been slid (Yes in step S103), the display position changing unit 215 detects the slide amount detected on the entire display unit including the lens information display unit 24 and the lens operation display unit 23. Control to move in the direction is performed (step S104). Thereafter, the process proceeds to step S105. Step S105 and subsequent steps are as described above.

  When the slide of the lens information display unit 24 cannot be detected (No in step S103), it is detected whether the touch state of the lens information display unit 24 is maintained (step S111). When the touch state of the lens information display unit 24 is maintained (Yes in step S111), it is detected whether the lens operation display unit 23 has been slid (step S112). When the slide of the lens operation display unit 23 is not detected (No in step S112), the process proceeds to step S105. Step S105 and subsequent steps are as described above. When the slide of the lens operation display unit 23 is detected (Yes in step S112), the display position changing unit 215 performs control to move the lens operation display unit 23 in the detected slide amount and direction (step S113).

  When the touch state of the lens information display unit 24 is not maintained (when the finger is separated) (No in step S111), the movement mode of the lens information display unit 24 is set (step S121). It is detected whether or not the lens information display unit 24 is slid in the movement mode state of the lens information display unit 24 (S122). When the slide of the lens information display unit 24 is not detected (No in step S122), the process proceeds to step S105. Step S105 and subsequent steps are as described above. When the slide of the lens information display unit 24 is detected (Yes in step S122), the display position changing unit 215 performs control to move the lens information display unit 24 in the detected slide amount and direction (step S123).

  If the power is turned off (Yes in step S131), the process ends. If power OFF is not detected (Yes in step S5), the process returns to the step (step S2) of detecting whether or not the lens information display unit 4 has been touched.

  As described above, the touch panel is arranged along the circumferential direction on the outer periphery of the lens barrel, and the display position of the display unit can be changed to a predetermined position by operating the lens information display unit. In addition, a posture determination unit is provided to automatically change the display position of the display unit when the posture is changed. Therefore, without changing the number of parts, when the photographer's holding state changes when the posture is changed, the display can be automatically changed to a position where the photographer can easily operate. be able to.
