Best Mode for Carrying Out the Invention

[0010] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In each figure, the same members are denoted by the same reference numerals, and duplicate explanations are omitted.

[0011] FIG. 1 is a configuration diagram of a camera system according to an embodiment of the present invention. The camera system includes an interchangeable lens (lens device) 100 and a camera (imaging device) 10 to which the interchangeable lens 100 can be attached. The interchangeable lens 100 is mechanically and electrically connected to the camera 10 via a lens mount 103 and a camera mount 24. The interchangeable lens 100 receives power supply from the camera 10 via electrical terminals (not shown) provided on the aforementioned mount. The camera 10 communicates with the interchangeable lens 100 via communication terminals (not shown) provided on the aforementioned mount.

[0012] The camera 10 has an imaging element 11 that photoelectrically converts a subject image formed by a right-eye lens unit 101R and a left-eye lens unit 101L in the interchangeable lens 100 and outputs an electrical signal. The camera 10 also has an A / D conversion unit 12 that converts an analog electrical signal output from the imaging element 11 into a digital signal, and an image processing unit 13 that performs various image processes on the digital signal to generate an image. The image generated by the image processing unit 13 is displayed on the display unit 14 and recorded on the recording medium 18.

[0013] Furthermore, the camera 10 has an operation unit 15 including a power switch for turning the power on / off, a shooting switch for starting recording of an image or video, and a selection / setting switch for setting the camera 10 and the interchangeable lens 100. The camera control unit 17 includes a microcomputer and controls the image processing unit 13 and communication control with the interchangeable lens 100 according to signals from the operation unit 15.

[0014] The interchangeable lens 100 has prisms 106R, 107R, 106L, and 107L that change the direction of the optical axis by 90 degrees through reflection. The interchangeable lens 100 also has a lens control unit 104 that includes a microcomputer that controls the aperture and focus in response to a control signal received by communication from the camera control unit 17 and the operation of a lens operation unit 115. The lens operation unit 115 is an operation member that includes a setting switch that can change the operation of the lens and a ring operation unit that performs focus and aperture operations. The lens control unit 104 performs control in response to the operation on the lens operation unit 115.

[0015] 2 is a configuration diagram of the camera control unit 17 and the lens control unit 104. The LCLK terminal (1-1) is a terminal for a communication control signal output from the camera 10 to the interchangeable lens 100. The DCL terminal (1-2) is a terminal for communication data output from the camera 10 to the interchangeable lens 100. The DLC terminal (1-3) is a terminal for communication data output from the interchangeable lens 100 to the camera 10. The MIF terminal (1-4) is a terminal for detecting that the interchangeable lens 100 is attached to the camera 10. A microcomputer (hereinafter, referred to as a camera microcomputer) 20 in the camera control unit 17 detects that the interchangeable lens 100 is attached to the camera 10 based on the voltage of the MIF terminal (1-4). The TYPE terminal (1-5) is a terminal for detecting the type of the interchangeable lens 100 attached to the camera 10. The camera microcomputer 20 detects the type of the interchangeable lens 100 attached to the camera 10 based on the voltage of the TYPE terminal (1-5). The VBAT terminal (1-6) is a terminal for supplying a driving power source (VM) used for various operations except communication control from the camera 10 to the interchangeable lens 100. The VDD terminal (1-7) is a terminal for supplying a communication control power source (VDD) used for communication control from the camera 10 to the interchangeable lens 100. The DGND terminal (1-8) is a terminal for connecting the communication control systems of the camera 10 and the interchangeable lens 100 to ground. The PGND terminal (1-9) is a terminal for connecting a mechanical driving system including a motor etc. provided in the camera 10 and the interchangeable lens 100 to ground.

[0016] A plurality of types of interchangeable lenses 100, each of which has a different communication voltage with the camera 10, are selectively attached to the camera 10. Below, a case will be described in which the types of interchangeable lenses 100 identified by the camera 10 based on the voltage of the TYPE terminal (1-5) include a first interchangeable lens and a second interchangeable lens having a different communication voltage from the first interchangeable lens.

[0017] The camera power supply unit 21 provided in the camera control unit 17 converts the battery voltage supplied from a battery (not shown) mounted on the camera 10 into a voltage required for the operation of each circuit. At this time, the camera power supply unit 21 generates a first voltage V1, a second voltage V2, a third voltage V3, and a voltage VM. The first voltage V1 is a power supply voltage serving as a communication control power supply (VDD) for the first and second interchangeable lenses, and is also a communication voltage for the first interchangeable lens. The second voltage V2 is a communication voltage for the second interchangeable lens. The third voltage V3 is a power supply voltage serving as an operating power supply for the camera microcomputer 20. The voltage VM is a power supply voltage serving as a driving power supply for the first and second interchangeable lenses.

[0018] When the power switch 22 is turned on, the camera microcomputer 20 starts supplying the communication control power supply (VDD) and the voltage VM from the camera 10 to the interchangeable lens 100. When the power switch 22 is turned off, the camera microcomputer 20 stops supplying the communication control power supply (VDD) and the voltage VM from the camera 10 to the interchangeable lens 100.

[0019] The camera microcomputer 20 communicates with the interchangeable lens 100 via the voltage conversion unit 23. The camera microcomputer 20 has an LCLK_OUT terminal that outputs a communication control signal, a DCL_OUT terminal that outputs communication data to the interchangeable lens 100, and a DLC_IN terminal that receives input of communication data from the interchangeable lens 100. The communication control signal and communication data correspond to communication signals. The camera microcomputer 20 also has a MIF_IN terminal for detecting attachment of the interchangeable lens 100, a TYPE_IN terminal for identifying the type of the interchangeable lens 100, and a CNT_V_OUT terminal that outputs a communication voltage switching signal to the voltage conversion unit 23. The camera microcomputer 20 also has a CNT_VDD_OUT terminal that outputs a power supply signal for the power switch 22, a connection terminal with the image processing unit 13, and a connection terminal with the operation unit 15.

[0020] A microcomputer (hereinafter referred to as lens microcomputer) 111 in the lens control unit 104 communicates with the camera microcomputer 20 via the voltage conversion unit 23. The lens microcomputer 111 has an LCLK_IN terminal that receives an input of a communication control signal, a DLC_OUT terminal that outputs communication data to the camera 10, and a DCL_IN terminal that receives an input of communication data from the camera 10. The lens microcomputer 111 also has connection terminals with the right aperture driving unit 105R, the left aperture driving unit 105L, the binocular focus driving unit 110, and the left-right relative focus difference adjustment driving unit 112. The lens control unit 104 also has a lens power supply unit 114.

[0021] The MIF_IN terminal of the camera microcomputer 20 is pulled up to the power supply by resistor R2 (100 KΩ), so the voltage value is H (High) when no lens is attached. However, when an interchangeable lens (first and second interchangeable lenses) 100 is attached, the MIF_IN terminal is connected to GND at the interchangeable lens 100, so the voltage value becomes L (Low) when the interchangeable lens 100 is attached regardless of the type of interchangeable lens 100.

[0022] The interchangeable lens 100 has a right aperture drive unit 105R and a left aperture drive unit 105L that drive actuators that operate the right aperture unit 102R and the left aperture unit 102L. The interchangeable lens 100 also has a binocular focus drive unit 110 that operates the binocular focus unit 108. The interchangeable lens 100 also has a left-right relative focus difference adjustment drive unit 112 that operates the left-right relative focus difference adjustment unit 109.

[0023] 1, the left-right relative focus difference adjustment unit 109 is disposed on the right eye side, but it may be disposed on the left eye side. In this embodiment, two aperture drive units are provided, but one aperture drive unit may be configured to drive two aperture units simultaneously. The binocular focus drive unit 110 may be an integrated left-right drive mechanism, or separate left-right drive mechanisms may be operated simultaneously by separate motors.

[0024] FIG. 3 is a schematic diagram of the focus difference adjustment between the right-eye optical system and the left-eye optical system. The right-eye optical system and the left-eye optical system are arranged in parallel, one of which functions as the first optical system and the other as the second optical system. In the compound lens unit, a focus difference may occur between the right-eye optical system and the left-eye optical system due to variations in the imaging surface tilt due to individual differences in cameras and changes in reliability (temperature, humidity, impact, etc.). FIG. 3(a) shows a state when the imaging surface of the imaging element 11 is not tilted. Ideally, the imaging surface should not be tilted as shown in FIG. 3(a), but the imaging surface may be tilted as shown in FIG. 3(b) due to individual differences in cameras. In the configurations of FIG. 1 and FIG. 2, the focus positions of the left and right eyes can be changed using the left and right relative focus difference adjustment unit 109. As shown in FIG. 3(b), after adjusting the focus positions of the left and right eyes, the left and right optical systems are moved synchronously using the binocular focus unit 108, making it possible to take pictures in a state that matches the tilt of the imaging surface.

[0025] In this embodiment, the interchangeable lens 100 operates the binocular focus drive unit 110 in the first drive mode (first mode) and operates the left / right relative focus difference adjustment drive unit 112 in the second drive mode (second mode). That is, in the first drive mode, the left and right optical systems can be driven simultaneously, and in the second drive mode, the left and right optical systems can be driven independently. EXAMPLES

[0026] In this embodiment, a flow will be described in which the interchangeable lens 100 operates in response to the operation of the lens operation unit 115. Fig. 4 is a flowchart explaining the operation of the interchangeable lens 100 in this embodiment. When the operation unit 15 is operated or the interchangeable lens 100 is attached to the camera 10, power is supplied from the camera 10 to the interchangeable lens 100, and the flow starts.

[0027] In step S101, the lens control unit 104 performs an initial process after power-on. FIG. 4B is a flowchart showing the initial process. In step S111, the lens power supply unit 114 receives power from the camera 10 and starts supplying power to each unit in the interchangeable lens 100. In step S112, the lens control unit 104 sets the focus drive mode to the first drive mode. In step S113, the lens control unit 104 moves the right aperture unit 102R and the left aperture unit 102L to their initial positions via the right aperture drive unit 105R and the left aperture drive unit 105L. Here, the initial positions are usually positions where the aperture is open (open position), but may not be the open position depending on the settings of the camera 10, etc. In step S114, the lens control unit 104 moves the binocular focus unit 108 to its initial position via the binocular focus drive unit 110. Here, the initial position is usually a position where the aperture is optically infinity, but may be a position where the power was turned off last time depending on the settings of the camera 10, etc.

[0028] In step S102, the lens control unit 104 determines whether or not there has been a change in the state of the switching means for the focus driving mode included in the lens operation unit 115. If the lens control unit 104 determines that the state of the switching means has changed, it executes the process of step S103, and if it determines that the state of the switching means has not changed, it repeats the process of this step.

[0029] In step S103, the lens control unit 104 determines whether the state of the switching means is a state that indicates the first drive mode. If the lens control unit 104 determines that the state of the switching means is a state that indicates the first drive mode, it executes the process of step S104. If the lens control unit 104 determines that the state of the switching means is not a state that indicates the first drive mode, that is, a state that indicates the second drive mode, it executes the process of step S105.

[0030] In step S104, the lens control unit 104 transmits information requesting a display indicating the normal state to the camera 10. That is, the lens control unit 104 functions as a transmission unit.

[0031] In step S105, the lens control unit 104 transmits to the camera 10 information requesting a display indicating a state different from the normal state.

[0032] After executing the process of step S104 or step S105, the lens control unit 104 executes the process of step S102.

[0033] The camera microcomputer 20 receives information transmitted from the interchangeable lens 100 (information transmitted in step S104 or step S105). The information transmitted in step S104 or step S105 corresponds to the state of the switching means. That is, the camera microcomputer 20 functions as an acquisition unit capable of acquiring the state of the switching means. The camera microcomputer 20 also causes the display unit 14 to display a display corresponding to the received information. That is, the camera microcomputer 20 functions as a display control unit that controls the display (content) to be displayed on the display unit 14 according to the state of the switching means. For example, when the camera microcomputer 20 receives information requesting a display showing a normal state from the interchangeable lens 100, it causes the display unit 14 to display the display shown in FIG. 5(a) (first display). The display shown in FIG. 5(a) is a normal display (a display indicating a state indicating that there is no effect on taking pictures, i.e., a display indicating that taking pictures is possible). Furthermore, when the camera microcomputer 20 receives information from the interchangeable lens 100 requesting a display indicating a state different from the normal state, it causes the display unit 14 to display the display shown in Fig. 5(b) (second display). The display shown in Fig. 5(b) is a display different from the normal display in Fig. 5(a) (a display that can make the user aware that the state is different from a state in which photography is possible).

[0034] As described above, according to the configuration of this embodiment, when adjusting the focus difference between the left and right optical systems (the focus drive mode is the second drive mode), a display different from the normal display is displayed, thereby preventing the user from mistakenly performing a shooting operation. EXAMPLES

[0035] In this embodiment, a case will be described where additional information is displayed on the display shown in embodiment 1. Fig. 6 is a flowchart explaining an example of the operation of the interchangeable lens 100 of this embodiment. When the operation unit 15 is operated or the interchangeable lens 100 is attached to the camera 10, power is supplied from the camera 10 to the interchangeable lens 100, and the flow starts.

[0036] Step S201 is similar to the process of step S101 in FIG. 4, and therefore a description thereof will be omitted.

[0037] In step S202, the lens control unit 104 determines whether or not there has been a change in the state of the focus driving mode switching means included in the lens operation unit 115. If the lens control unit 104 determines that the state of the switching means has changed, it executes the process of step S203, and if it determines that the state of the switching means has not changed, it executes the process of step S206.

[0038] The processes in steps S203 to S205 are similar to those in steps S103 to S105 in FIG. 4, respectively, and therefore will not be described.

[0039] In step S206, the lens control unit 104 determines whether the state of the switching means is a state that indicates the first drive mode. If the lens control unit 104 determines that the state of the switching means is a state that indicates the first drive mode, it executes the process of step S207. If the lens control unit 104 determines that the state of the switching means is not a state that indicates the first drive mode, that is, a state that indicates the second drive mode, it executes the process of step S208.

[0040] In step S207, lens control unit 104 transmits information for displaying distance information (information related to shooting distance) to camera 10. Camera 10 performs display according to the information for displaying distance information. In this embodiment, camera 10 performs display as shown in FIG. 7(a). Specifically, a display is performed in which a bar-shaped display shown at the bottom, a distance number shown at the top of the bar, and a mark showing the current focus position shown on the bar are added to the display of FIG. 5(a). A combination of these displays indicates the distance of the current focus position, and the display makes it easy to intuitively grasp where in the focus range the current focus position is located.

[0041] The information transmitted in step S207 includes information about the position of the bar displaying the distance number, information about the number displaying the distance, and information about the position of the bar showing the current focus position. By performing display based on this information, the camera 10 can display the focus position information in an easy-to-understand manner for the user.

[0042] In step S208, the lens control unit 104 transmits information for displaying the difference between the focus positions of the right eye focus unit and the left eye focus unit to the camera microcomputer 20. The camera microcomputer 20 performs display according to the information for displaying the difference between the focus positions of the right eye focus unit and the left eye focus unit. In this embodiment, the display shown in FIG. 7(b) is performed. Specifically, a display showing the difference between the focus positions of the right eye and the left eye is added to the display of FIG. 5(b) where the distance information is displayed in the display of FIG. 7(a). In the display of FIG. 7(b), the center of the bar is "0", and a state where there is a mark at the "0" position indicates a state where there is no difference between the focus positions of the right eye and the left eye. The plus side to the right of "0" indicates the amount of adjustment when adjusted toward infinity, and the minus side to the left of "0" indicates the amount of adjustment when adjusted toward the close distance. The numbers on the scale indicate the range that can be adjusted, and since a stepping motor is assumed to drive the focus in this embodiment, the numbers indicate the number of drive pulses that can be used for adjustment. The numbers may be the amount of movement converted into focus or the difference in distance of the focus lens. By checking the display in Fig. 7(b), the user can understand the amount of adjustment of the focus positions of the right eye and the left eye.

[0043] The information transmitted in step S208 includes information on the position of a bar displaying numbers used in a scale for indicating the difference between the focus positions of the right eye and the left eye, information on the numbers used in the scale, and information on the position of a bar indicating the difference between the focus positions of the right eye and the left eye. The camera 10 can display the difference in focus positions between the right eye focus unit and the left eye focus unit by performing display based on this information. In other words, the camera 10 can display the distance display and the focus difference display without any distinction, and can control which display to perform based on information from the interchangeable lens 100.

[0044] FIG. 8 is a flowchart illustrating another example of the operation of the interchangeable lens 100 of this embodiment.

[0045] The processes in steps S301 to S305 are similar to those in steps S201 to S205 in FIG. 6, respectively, and therefore will not be described.

[0046] In step S306, the lens control unit 104 resets a timer for measuring time, and then starts counting.

[0047] In step S307, the lens control unit 104 determines whether the state of the switching means is a state that indicates the first drive mode. If the lens control unit 104 determines that the state of the switching means is a state that indicates the first drive mode, it executes the process of step S312. If the lens control unit 104 determines that the state of the switching means is not a state that indicates the first drive mode, that is, a state that indicates the second drive mode, it executes the process of step S308.

[0048] In step S308, the lens control unit 104 determines whether a predetermined time has elapsed. If the lens control unit 104 determines that the predetermined time has elapsed, it executes the process of step S309, and if it determines that the predetermined time has not elapsed, it executes the process of step S302.

[0049] In step S309, the lens control unit 104 resets a timer for measuring time, and then starts counting.

[0050] In step S310, the lens control unit 104 determines whether the information previously transmitted to the camera 10 is distance information. If the lens control unit 104 determines that the information previously transmitted to the camera 10 is distance information, it executes the process of step S311, and if it determines that the information previously transmitted to the camera 10 is not distance information, that is, if it determines that the information is focus difference information, it executes the process of step S312.

[0051] The processes in steps S311 and S312 are similar to those in steps S208 and S207 in FIG. 6, respectively, and therefore will not be described.

[0052] By performing the above-described processing, the camera 10 alternately displays Figures 9(a) and 9(b) at predetermined time intervals. The camera 10 may alternately display the distance information of the right eye optical system and the distance information of the left eye optical system at predetermined time intervals.
