(First embodiment)
A first embodiment of the present invention will be described using an interchangeable lens type digital camera as an example.

FIG. 1 is a block diagram showing the configuration of the camera system of the first embodiment. FIG. 2 is a block diagram showing the configuration of various types of interchangeable lenses. FIG. 3 is an external view of the digital camera 100 and interchangeable lens 200 of the first embodiment.

A system configuration of the camera 100 will be described with reference to FIG.

An optical image is formed on the imaging unit 103 through the interchangeable lens 200 and the shutter 102 . An imaging unit 103 is an imaging element configured by a CCD, a CMOS element, or the like that converts an optical image into an electric signal. The A/D converter 104 converts the analog signal output from the imaging unit 103 into a digital signal. The image processing unit 105 performs resizing processing such as predetermined pixel interpolation and reduction, and color conversion processing on the data from the A/D converter 104 or the data from the memory control unit 106 .

Also, the image processing unit 105 performs predetermined arithmetic processing using image data obtained by imaging, and the system control unit 101 performs exposure control and ranging control based on the obtained arithmetic results. As a result, TTL (through-the-lens) AF processing, AE (auto exposure) processing, and EF (flash pre-emission) processing are performed. The image processing unit 105 further performs predetermined arithmetic processing using image data obtained by imaging, and also performs TTL AWB (Auto White Balance) processing based on the obtained arithmetic results.

Data output from the A/D converter 104 is directly written into the memory 107 via the image processing unit 105 and the memory control unit 106 or via the memory control unit 106 . The memory 107 stores image data obtained by the imaging unit 103 and converted into digital data by the A/D converter 104 and image data to be displayed on the display unit 109 . The memory 107 has a storage capacity sufficient to store a predetermined number of still images, moving images for a predetermined period of time, and audio.

The memory 107 also serves as an image display memory (video memory). The D/A converter 108 converts image display data stored in the memory 107 into an analog signal and supplies the analog signal to the display unit 109 . Thus, the image data for display written in the memory 107 is displayed by the display unit 109 via the D/A converter 108 .

The display unit 109 displays on a display such as an LCD in accordance with the analog signal from the D/A converter 108 . A digital signal that has been A/D converted once by the A/D converter 108 and stored in the memory 107 is converted to analog by the D/A converter 108, and is sequentially transferred to the display unit 109 for display. It functions and enables through image display (hereinafter referred to as live view image).

The nonvolatile memory 110 is an electrically erasable/recordable memory, and for example, an EEPROM or the like is used. The nonvolatile memory 110 stores constants for operation of the system control unit 101, programs, and the like. The program here is a program for executing various flowcharts described later.

A system control unit 101 controls the entire camera 100 . By executing the program recorded in the non-volatile memory 110 described above, each process described later is realized. A system memory 111 uses a RAM. In the system memory 111, constants and variables for operation of the camera system control unit 101, programs read from the nonvolatile memory 110, and the like are expanded. The camera system control unit 101 also performs display control by controlling the memory 107, the D/A converter 108, the display unit 109, and the like. A system timer 112 is a timer that measures the time used for various controls and the time of a built-in clock.

A shutter button 113 , a mode switching dial 116 , a power button 117 , a focus mode switching switch 118 , and an operating section 119 are operating means for inputting various operation instructions to the camera system control section 101 .

A mode switching dial 116 switches the operation mode of the camera system control unit 101 to a still image recording mode, a moving image recording mode, a reproduction mode, and a detailed mode included in each operation mode.

The first shutter switch 114 (SW1 (114)) is turned on when the shutter button 113 is being operated, that is, when the shutter button 113 is half-pressed (imaging preparation instruction), and the first shutter switch signal SW1 is generated. Operations such as AF processing, AE processing, AWB processing, and EF processing are started by the first shutter switch signal SW1.

The second shutter switch 115 (SW2 (115)) is turned ON when the operation of the shutter button 113 is completed, that is, when the shutter button 113 is fully pressed (imaging instruction), and generates a second shutter switch signal SW2. The camera system control unit 101 starts a series of shooting processing operations from signal reading from the imaging unit 103 to writing image data to the recording medium 125 in response to the second shutter switch signal SW2.

The power control unit 120 is composed of a battery detection circuit, a DC-DC converter, a switch circuit for switching blocks to be energized, and the like, and detects the state of the power button 117, whether or not a battery is installed, the type of battery, and the remaining amount of the battery. . Also, the power supply control unit 120 controls the DC-DC converter based on the detection results and instructions from the camera system control unit 101, and supplies necessary voltage to each unit including the recording medium 125 for a necessary period.

The power supply unit 121 includes a primary battery such as an alkaline battery or a lithium battery, a secondary battery such as a NiCd battery, a NiMH battery, or a Li battery, an AC adapter, or the like. In the present embodiment, a case where a secondary battery is used for a power source (hereinafter referred to as a battery) will be described.

The camera 100 can issue a notification such as a warning by voice, and can make the speaker 123 emit the voice generated by the voice control unit 122 .

A recording medium I/F 124 is an interface with a recording medium 125 such as a memory card or hard disk. A recording medium 125 is a recording medium such as a memory card for recording captured images, and is composed of a semiconductor memory, a magnetic disk, or the like.

Each operation member of the operation unit 119 is appropriately assigned a function for each scene by selecting and operating various function icons displayed on the display unit 109, and acts as various function buttons. The function buttons include, for example, an end button, a return button, an image forward button, a jump button, a refinement button, an attribute change button, and the like.

For example, as shown in FIG. 3A, when the menu button 301 on the back of the imaging device body of the camera 100 is pressed, a menu screen for various settings is displayed on the display unit 109 . The user can intuitively perform various settings by using the menu screen displayed on the display unit 109 and the cross button 302 and the SET button 303 having buttons in four directions of up, down, left, and right. A controller wheel 304 and an electronic dial 305 are rotatable operation members included in the operation unit 119, and are used together with direction buttons to indicate selection items.

When the controller wheel 304 or the electronic dial 305 is rotated, an electrical pulse signal is generated according to the amount of operation, and the camera system control section 101 controls each section of the camera 100 based on this pulse signal. From this pulse signal, it is possible to determine the angle by which the controller wheel 304 or the electronic dial 305 is rotated, how many times it has been rotated, and the like. Note that the controller wheel 304 and the electronic dial 305 may be any operating member that can detect a rotating operation. For example, it may be a dial operation member that generates a pulse signal by rotating the controller wheel 304 or the electronic dial 305 itself according to a user's rotation operation. Alternatively, the operation member may be a touch sensor that does not rotate the controller wheel 304 itself and that detects the rotation of the user's finger on the controller wheel 304 (so-called touch wheel).

The focus mode switching switch 118 (first switching means) is a lever-shaped mechanical switch (lever switch) provided on the outer surface of the main body of the camera 100 . By switching the index position at the tip of the focus mode switching switch 118, AF and MF can be switched. Since the index position of the focus mode switching switch 118 can be visually recognized from the outside of the camera 100, the user can easily confirm which mode of focus control is currently set on the camera 100 side. can. That is, the focus mode switching switch 118 has good visibility and operability for the user.

A battery 121 and a recording medium 125 can be inserted from the bottom surface of the camera 100, and the cover 306 can be opened and closed.

The wireless communication I/F 126 can perform wireless communication with an external device. Via the wireless communication I/F 126, image data obtained by photography can be transmitted to terminals such as other cameras, mobile terminals, and PCs. Moreover, it is also possible to remotely control the camera 100 from the portable terminal to take an image through communication via the wireless communication I/F 126 .

The lens communication I/F 127 is an interface for electrically communicating (lens communication) with the interchangeable lens 200 attached to the camera 100 . Through lens communication, it is possible to issue a lens driving instruction and state notification regarding a focus control mode set on the interchangeable lens 200 side. In addition, although not shown, the camera 100 has a mount as a mounting member that allows the interchangeable lens 200 to be detachable.

The system configuration of various types of interchangeable lenses 200 will be described with reference to FIG. There are two types of focus systems for interchangeable lenses: electronic focus and mechanical focus.

FIG. 2A is a system diagram of an electronic focus lens (with a focus mode switch 205). Lens control is performed by a lens system control unit 201 . A lens 202 is a lens group for focusing. A lens drive unit 203 including a motor and gears is mechanically connected to the focus lens 202 and moves the focus lens 202 by operating the lens drive unit 203 .

The focus operation unit 204 is, for example, a ring-shaped operation member, and the user can perform focus adjustment (focus control) by manually operating the focus operation unit 204 (MF). A focus mode switching switch 205 (second switching means) is an operation member for switching the focus control mode between AF and MF on the interchangeable lens 200 side. Control signals are communicated between the interchangeable lens 200 and the main body of the camera 100 via the camera communication I/F 206, and information such as whether or not there is a focus mode switch on the interchangeable lens side and focus drive method (electronic/mechanical). , focus control mode (AF/MF) setting information and the like are transmitted from the interchangeable lens 200 to the camera body 100 .

When an electronic focus lens is attached to the camera 100 and AF is set, the interchangeable lens 200 receives an AF operation instruction from the camera 100, and the lens system control unit 201 controls the lens driving unit 203 to focus. Move the lens 202 . Further, when MF is set, when the focus operation unit 204 is rotated, a pulse signal corresponding to the rotation angle is generated. It controls the drive unit 203 . Since the movement control of the lens is electronically performed, even if the focus mode switch 205 is set to AF setting, it is possible to execute control similar to MF setting by an instruction from the camera body 100 . Conversely, AF operation can be performed even if the focus mode changeover switch 205 is set to MF (control to ignore the setting of the focus mode changeover switch 205 is possible).

FIG. 2B is a system diagram of the mechanical focus lens. Each block is the same as the electronic focus lens in FIG. 2A, but in the mechanical focus lens, the lens driving unit 203 and the focus lens 202 can be mechanically switched between connection and non-connection. This switching is interlocked with the AF position and the MF position of the focus mode switching switch 205. When the switch is in the AF position, it is connected, and when it is in the MF position, it is not connected. When AF is set, an AF operation instruction is received from the camera body 100 , and the lens system control unit 201 controls the lens driving unit 203 to move the focus lens 202 .

On the other hand, when the MF is set, the lens drive unit 203 is mechanically separated from the focus lens 202 , so the focus lens 202 can be moved by rotating the focus operation unit 204 . Since the movement control of the lens is mechanically performed, when the focus mode switching switch 205 is set to AF, the lens drive unit 203 mechanically connected to the focus lens acts as a load, and the focus operation unit 204 must be manually rotated. can't Conversely, when the focus mode changeover switch 205 is set to MF, the lens driving unit 203 is mechanically separated from the focus lens 202, so the AF operation cannot be performed (the setting of the focus mode changeover switch 205 cannot be ignored). .

FIG. 2C is a system diagram of an electronic focus lens (without the focus mode switch 205). FIG. 2-3 has the same configuration as FIG. 2-1 except that the focus mode switch 205 is not provided. Since this interchangeable lens cannot switch the focus mode on the lens side, the setting state of the focus mode is acquired from the camera body 100 and the lens is electronically controlled.

FIG. 3B is an external view showing a state in which the interchangeable lens 200 is attached to the camera 100. FIG. A focus mode switch 204 is located on the side of the lens. Note that the lens having the structure shown in FIG. 2C does not have a focus mode switch.

Further, in the present embodiment, when the interchangeable lens 200 having the focus mode switching switch 205 (hereinafter referred to as the lens side switch 205) is attached to the camera 100, the setting of the lens side switch 205 on the lens side is prioritized. will be described with reference to the flowchart of FIG.

When the power of the camera 100 is turned on, a flag (hereinafter referred to as a camera side switch flag) indicating whether the camera side focus mode switch 118 (hereinafter referred to as a camera side switch 118) is enabled/disabled is set to an initial value of disabled. (S401). After that, the camera 100 enters a photographing standby state and monitors each processing event.

When an event in which the interchangeable lens 200 is attached to the camera 100 is detected (S402), focus mode setting processing when the lens is attached is executed. First, it is determined whether or not the interchangeable lens 200 has the lens side switch 205 (S403). If it is determined that there is a lens side switch, the camera side switch flag is invalidated (S404).

Next, the setting state of the lens side switch 205 is confirmed (S405), and if the AF setting is selected, the current focus mode is set to AF (S406). If MF is set, the current focus mode is set to MF (S407).

On the other hand, if the mounted lens does not have a lens side switch , the camera side switch flag is validated (S408). Further, the setting state of the camera side switch 118 is confirmed (S409), and if the setting is AF, the current focus mode is set to AF (S410). Also, if the setting is MF, the focus mode is set to MF (S411).

After setting the focus mode, the current focus mode is displayed as guidance on the display unit 109 (S412). An example of guidance display is shown in FIG. FIG. 7A shows the case when AF is set, and FIG. 7B shows the case when MF is set.

When an event in which the camera side switch 118 is operated is detected in the shooting standby state, the camera side switch flag is checked (S414). If the flag is valid, the camera side switch setting state 118 is checked (S415). If the camera side switch setting is AF, the current focus mode is set to AF (S416). If it is MF, the current focus mode is set to MF (S417).

After setting the focus mode, the current focus mode is displayed as guidance on the display unit 109 (S418). An example of the guidance display is shown in FIGS. 7(A) and 7(B).

Further, if the camera side switch flag is invalid in S414, the user's focus mode operation using the camera side switch 118 is invalid, so guidance is displayed on the display unit 109 for effective switching operation methods (S419). An example of the guidance display is shown in FIG. 7(C).

When an event in which the lens side switch 205 is operated is detected in the shooting standby state, the setting state of the lens side switch is checked (S421), and if AF is set, the current focus mode is set to AF (S422). If it is MF, the focus mode is set to MF (S423).

After setting the focus mode, the current focus mode is displayed as guidance on the display unit 109 (S418). An example of the guidance display is shown in FIGS. 7(A) and 7(B). Note that the lens-side switch operation event is transmitted only when the interchangeable lens 200 attached to the camera 100 has a lens-side switch.

When an event in which the interchangeable lens 200 is removed from the camera 100 is detected in the shooting standby state, the current focus mode is set to MF (S426), and the camera side switch flag is disabled (S427). Then, the current focus mode is displayed as guidance on the display unit 109 (S428). An example of the guidance display is shown in FIG. 7(D).

Finally, when the power of the camera is turned off in the shooting standby state, the process ends.

According to the present embodiment, when the interchangeable lens 200 capable of switching between AF and MF is attached to the lens-interchangeable camera 100, focus control can be properly performed even if the settings on the camera body side and the lens side conflict. Another feature is that priority is given to the setting on the lens side regardless of whether the lens is an electronic focus lens or a mechanical focus lens. As described above, when the interchangeable lens 200 is an electronic focus, unlike mechanical focus, focus control is possible regardless of which setting is prioritized on the camera body side or the lens side. However, in the present embodiment, the user's confusion can be prevented by uniformly giving priority to the setting on the lens side regardless of the method.

(Second embodiment)
In the first embodiment, when the interchangeable lens 200 with the lens side switch 205 is attached to the camera 100, regardless of the type of the interchangeable lens 200, the setting of the camera side switch 218 is invalidated, and the lens side switch 205 is turned off. In this form, focus control is performed according to the setting. The second embodiment is characterized in that when the interchangeable lens 200 is an electronic focus, the user can set which of the camera-side switch 218 and the lens-side switch 205 should be prioritized.

The present embodiment will be described mainly with reference to FIGS. 5 and 6. FIG.

When the power of the camera 100 is turned on, the setting state of the menu setting is checked to determine which of the camera-side switch 118 and the lens-side switch 204 should be prioritized (S501). If the camera side switch 218 is prioritized, the camera side switch flag is enabled (S502), and the lens side switch flag is disabled (S503). If the lens side switch 205 is set to be prioritized, the camera side switch flag is disabled (S504), and the lens side switch is enabled (S505). After the initial setting at power-on is completed, the camera 100 enters a photographing standby state and monitors each processing event.

When an event that the interchangeable lens 200 is attached to the camera 100 is detected (S506), focus mode setting processing when the lens is attached is executed. First, it is determined whether or not the interchangeable lens 200 is a lens compatible with electronic focusing (S507). If it is not compatible with electronic focusing, that is, if it is a mechanical focusing lens, the focus mode setting of the interchangeable lens cannot be ignored, so the lens side setting takes precedence, and the camera side switch flag is set invalid (S508).

Furthermore, the lens side switch flag is set to valid (S509). Next, the setting state of the lens side switch 204 is checked (S510), and if the setting is AF, the current focus mode is set to AF (S511), and if it is MF, the focus mode is set to MF (S512). After the setting of the focus mode is completed, the current focus mode is displayed as guidance (S526). An example of the guidance display is shown in FIGS. 7(A) and 7(B).

If the attached interchangeable lens 200 is compatible with electronic focus (S507), it is determined whether or not the lens side switch is attached (S513). If the lens side switch 204 is not attached, it is necessary to change the focus mode on the camera body side, so the camera side switch flag is set to valid (S514) and the lens side switch flag is set to invalid (S515).

Next, the setting state of the camera side switch 118 is checked (S516), and if the setting is AF, the current focus mode is set to AF (S517), and if it is MF, the focus mode is set to MF (S518). . After the setting of the focus mode is completed, the current focus mode is displayed as guidance (S526). An example of the guidance display is shown in FIGS. 7(A) and 7(B).

If the lens side switch 204 is attached (S513), the setting state of the menu setting for which to give priority to the camera side switch 118 or the lens side switch 204 is checked (S519), and the camera side switch is set to give priority. If so, the setting state of the camera-side switch is checked (S520). If the setting is AF, the current focus mode is set to AF (S521), and if it is MF, the focus mode is set to MF (S522). Also, if the lens side switch 204 is set to have priority (S519), the setting state of the lens side switch is checked (S523). If the setting is AF, the current focus mode is set to AF (S524), and if it is MF, the focus mode is set to MF (S525). In either case, when the setting of the focus mode is completed, the current focus mode is displayed as guidance (S526). An example of the guidance display is shown in FIGS. 7(A) and 7(B).

When an event in which the camera side switch is operated is detected in the shooting standby state (S527), the camera side switch flag is checked (S528). If it is valid, the setting state of the camera side switch 118 is confirmed (S529). If the setting is AF, the current focus mode is set to AF (S530), and if it is MF, the focus mode is set to MF (S531). After setting the focus mode, the current focus mode is displayed as guidance on the display unit 109 (S532). An example of the guidance display is shown in FIGS. 7(A) and 7(B).

If the camera side switch flag is invalid in S528, the user's camera main body side focus mode change operation is invalid, so guidance is displayed on the display unit 109 for effective switching operation methods (S533). An example of the guidance display is shown in FIG. 7(C).

When an event in which the lens side switch is operated is detected in the shooting standby state (S534), the lens side switch flag is checked (S535). If it is valid, the setting state 204 of the lens side switch is confirmed (S536). If the setting is AF, the current focus mode is set to AF (S537), and if it is MF, the focus mode is set to MF (S538). After setting the focus mode, the current focus mode is displayed as guidance on the display unit 109 (S539).

If the lens side switch flag is invalid in S535, the lens side focus mode change operation by the user is invalid. 7(D). Note that the lens-side switch operation event is transmitted only when the attached interchangeable lens 200 has the lens-side switch 204 attached.

When an event that the interchangeable lens 200 is removed is detected in the shooting standby state (S541), the current focus mode is set to MF (S542), and the camera side switch flag is disabled (S543). Further, the lens side switch flag is disabled (S544), and the current focus mode is displayed as guidance on the display unit 109 (S545).

When the focus mode priority setting menu execution event is detected in the shooting standby state (S546), the setting menu screen is displayed (S547). An example of the setting menu screen is shown in FIGS. 7(E) and 7(F).

When the setting item is confirmed on the setting menu screen (S548), the current cursor selection state is checked (S549). If the camera side operation priority setting is set (FIG. 7(E)), the camera side switch flag is set to valid (S550), and the lens side switch flag is set to invalid (S551). If the lens side operation priority setting is set (FIG. 7F), the camera side switch flag is set to be disabled (S552), and the lens side switch flag is set to be enabled (S553). When the flag setting process is completed, the setting menu screen is terminated (S555), and the shooting standby screen is displayed. Also, if cancellation is executed on the setting menu screen (S554), the setting menu screen is terminated (S555) and the shooting standby state is restored.

When the power is turned off in the shooting standby state (S556), the focus mode switching process ends.

According to the present embodiment, when the wearable lens 200 is an electronic focus, the user can select the priority setting, thereby further improving the user's operability.

(Other embodiments)
The second embodiment is characterized in that the user can set which of the camera side switch 218 and the lens side switch 205 should be prioritized when the mounted interchangeable lens 200 is of electronic focus. However, as described above, when the interchangeable lens 200 is an electronic focus, focus control is possible regardless of which setting on the camera body side or on the lens side is prioritized, unlike mechanical focus. .

Therefore, as another embodiment, in the case of electronic focus, priority can be given to the settings on the camera side. As shown in FIG. 3A, the settings of the camera-side switch 118 are provided at positions that are easy to see. Therefore, in the event of conflicting settings, priority is given to the camera-side settings with better visibility, thereby improving the operability of the user. can be improved.

As another embodiment, in the case of electronic focus, if MF is set on either the camera body side or the lens side, the side on which MF is set can be prioritized. When the user wants to shoot in MF, he or she can set the camera to MF on either side.
