The camera according to a preferred embodiment of the present invention is a digital camera, has an imaging unit, converts an object image into an electrical signal by the imaging unit, and uses the image data based on the converted electrical signal to generate an object. The image is displayed in live view on a display unit arranged on the back of the main body or on the eyepiece viewfinder. The photographer determines the composition and the photo opportunity by observing the live view display. During the release operation, image data is recorded on the recording medium. The image data recorded on the recording medium can be reproduced and displayed on the display unit when the reproduction mode is selected.

  The lens barrel is provided with a display unit having a touch panel. This display unit can display functions such as zoom, manual focus, exposure compensation, and mode change, and operation images. By operating the touch panel, you can operate the lens barrel and camera body with the associated functions. And settings can be made.

  FIG. 1 is a side view of the camera according to the first embodiment. A main body side display unit 6 is provided on the back of the camera main body 10. The main body side display unit 6 includes a liquid crystal display (LCD), an organic EL display, and the like. Further, an eyepiece finder 30 is provided. The user can observe the live view display by the main body side display unit 6 and the eyepiece finder 30, and can perform various settings.

  In this embodiment, the lens barrel 20 is an interchangeable lens and is detachable from the camera body 10. A lens side display unit 28 is provided on the side surface of the lens barrel 20, and a touch panel 29 is disposed on the lens side display unit 28. When the user touches the lens side display unit 28, the touch panel 29 detects and outputs the touched position. Note that the touch panel 29 is not limited to a type that detects the position when the lens side display unit 28 is directly touched, but may be a type that detects a position when approaching the vicinity of the surface of the lens side display unit 28.

  FIG. 2 is a block diagram mainly showing an electrical configuration of the camera according to the present embodiment. In the lens barrel 20, a control unit 21, a communication unit 22, a drive unit 24, a memory 27, a lens side display unit 28, and a touch panel 29 are provided.

  The photographing lens 26 is composed of a single focal point or a variable focal length optical system, and forms a subject image. The photographing lens 26 is driven along the optical axis direction by the drive unit 24. When the photographic lens 26 is a single focus lens, the drive unit 24 can perform manual focus adjustment (manual focus) or automatic focus adjustment (auto focus), and the photographic lens 26 is a variable focal length lens (zoom lens). In some cases, manual and automatic focus adjustment and focal length adjustment (zooming) are performed.

  The control unit 21 has a controller such as a CPU (Central Processing Unit) and controls the lens barrel 20 in accordance with a program stored in the memory 27. That is, the control unit 21 communicates with the signal processing and control unit 1 in the camera body 10 via the communication unit 22, and receives various information in response to a request from the signal processing and control unit 1 in the camera body 10. Send.

  Further, the control unit 21 outputs parameter change information to the camera side based on a display pattern to be described later and a detection result by the touch panel 29. For example, when the user performs a touch operation according to a display pattern as shown in FIGS. 3B and 3C described later, this state is detected by the touch panel 29, and the parameter is changed to the camera body 10 side based on the detection result. Information is output (see S23 in FIG. 4).

  The memory 27 is composed of a nonvolatile memory such as a flash memory, and stores a control program as described above. Further, the memory 27 displays an operation image (see FIGS. 3C, 3E, and 3F) displayed on the main body side display unit 6 when performing lens association described later, and an operation displayed on the lens side display unit 28. An image for use (see FIGS. 3B and 3D) is stored. The memory 27 stores various data such as the lens type, the long focal length, the short focal length, the open aperture, and the optical characteristics of the photographing lens 26. These data are transmitted when the lens barrel 20 is attached to the camera body 10 or in response to a request signal from the camera body 10.

  As shown in FIG. 1, the lens-side display unit 28 is disposed on the side surface of the lens barrel 20 at a position where a finger can easily touch when the user holds the lens barrel 20. An operation image output from the control unit 21 is displayed on the lens side display unit 28.

  The touch panel 29 functioning as a touch detection unit is provided on the surface of the lens side display unit 28 or integrally with the lens side display unit 28, detects a position touched by the user, and outputs the detected position to the control unit 21. The touch panel 29 detects a touch state with respect to a display pattern displayed on the main body side display unit 6 described later. The control unit 21 transmits the detection result of the touch panel 29 to the signal processing and control unit 1 on the camera body 10 side via the communication unit 22 and the communication unit 11.

  In the camera main body 10, a signal processing and control unit 1, an image sensor 2, a recording unit 4, a main body side display unit 6, and a communication unit 11 are provided. The image sensor 2 is disposed at a position where a subject image is formed by the photographing lens 26, converts the subject image into an image signal, and outputs the image signal to the signal processing and control unit 1.

  The signal processing and control unit 1 performs signal processing of the image signal output from the image sensor 2 and controls the camera body 10 and the entire photographing system according to a program stored in a memory (not shown). The image data signal-processed by the signal processing and control unit 1 is output to the main body side display unit 6 to display a live view image and a reproduced image. The image data compressed by the signal processing and control unit 1 is recorded in the recording unit 4.

  In addition, the signal processing and control unit 1 selects and associates the operation on the touch panel 29 with the operation on the touch panel 29 while communicating with the control unit 21 on the lens barrel 20 side. That is, the touch panel and the function are associated with each other so that any one or a plurality of functions such as zoom, manual focus, exposure correction, and mode change are executed by operating the touch panel 29 on the lens barrel 20 side. In other words, the signal processing and control unit 1 includes a function icon (refer to 6f in FIG. 3C described later) and an operation unit icon (refer to 6e in FIG. 3C described later). When the touch detection unit (touch panel 29) detects that the function icon and the operation unit icon are associated with each other by the touch operation, the touch detection unit (touch panel 29) functions as an association unit that associates the touch detection unit with the function icon.

  As will be described later, the main body side display unit 6 displays a plurality of selectable display patterns for lens association. In association with the lens, a function icon indicating a plurality of functions (see 6f in FIG. 3C described later) and an operation unit icon indicating the touch detection unit (touch panel 29) (refer to 6e in FIG. 3C described later). ) Is displayed.

  The communication unit 11 is connected to the communication unit 22 of the lens barrel 20 when the lens barrel 20 is attached to the camera body 10. The signal processing and control unit 1 communicates with the control unit 21 on the lens barrel 20 side via the communication unit 11 and the communication unit 22 on the lens barrel 20 side.

  Next, a lens association operation method according to the present embodiment will be described with reference to FIG. FIG. 3A is a side view of the camera according to the present embodiment shown in FIG. In the present embodiment, as described above, the main body side display unit 6 is provided on the back surface of the camera main body 10, and the lens side display unit 28 and the touch panel 29 are disposed on the side surface of the lens barrel 20. ing.

  When the lens barrel 20 is attached to the camera body 10 or when an association operation is performed on the camera body 10, an operation function is associated with the touch panel 29 provided on the lens barrel 20. In order to associate the operation functions, an operation image as shown in FIG. 3B is transmitted from the lens barrel 20 to the camera body 10 when the lens barrel 20 is attached to the camera body 10 or the like. The signal processing and control unit 1 displays the received operation image on the main body side display unit 6, and the user selects one of the operation images on the menu screen or the like.

  In the present embodiment, as shown in FIG. 3B, the operation image is provided with four types of patterns: a first pattern 6a, a second pattern 6b, a third pattern 6c, and a fourth pattern 6d. Here, the first pattern 6a displays two buttons on the left and right, and the second pattern 6b displays two buttons on the top and bottom. The third pattern 6c displays one horizontal bar, and the fourth pattern 6d displays two vertical bars.

  As described above, in the present embodiment, the first to fourth patterns 6a to 6d are displayed on the main body side display unit 6. Which pattern is displayed is set on the menu screen or the like on the camera main body side. deep. Of course, this setting can be changed as appropriate. In the present embodiment, the first to fourth patterns 6a to 6d are displayed. However, the present invention is not limited to this, and some of the patterns are omitted, and different patterns such as a rotation instruction pattern and three or more buttons are displayed. Alternatively, three or more bar displays may be added.

  FIG. 3C shows a display on the main body side display unit 6 when the third pattern 6c is set. On the main body side display unit 6, a selection pattern 6e, a function icon 6f, and an end icon 6g are displayed. The selection pattern 6e displays the currently set pattern among the first to fourth patterns. In the example of FIG. 3C, the third pattern 6c is displayed. The function icon 6f displays functions that can be associated. In the example of FIG. 3C, five types of functions are displayed: zoom, manual focus (MF), exposure correction, shutter speed priority (SS) mode, and multi-recording mode. Of course, the present invention is not limited to this, and some of the functions may be omitted and different functions may be added. The end icon 6g is used to end the association operation between the selection pattern 6e and the function icon 6f.

  When the operation image as shown in FIG. 3C is displayed, when the user associates the function desired by the user with the touch panel 29 while viewing the operation image, the lens barrel is used. The association operation may be performed on the touch panel 29 on the 20 side. For example, when the user wants to perform zooming by operating the touch panel 29, the position on the touch panel 29 corresponding to the “zoom” of the function icon 6f (upper right) is directed to the position corresponding to the selection pattern 6e (middle left). When the sliding operation (sliding operation) is performed, the signal processing and control unit 1 performs association. When this association is completed, the camera body 10 can perform zooming by transmitting the selected pattern to the lens barrel 20 and performing a sliding operation on the touch panel 29. That is, when the association is made, the associated function is controlled based on the detection output of the touch panel 29.

  FIG. 3D shows the display on the lens side display unit 28 when the third pattern 6c and zoom are associated with each other. In this state, as shown in the figure, a bar display 28c corresponding to the third pattern 6c is made in the approximate center of the screen. The focal length is changed when the user slides left and right on the lens side display unit 28, and the control unit 21 adjusts the focal length of the photographing lens 26 according to the detection output from the touch panel 29. The shaded portion of the bar display 28c indicates the currently set focal length. When zoomed to the tele side or wide side, the position of the shaded portion moves.

  A selection function 28b is displayed on the upper right side of the lens side display unit 28, and a mode change icon 28a is displayed on the upper left side. As the selection function 28b, a function currently associated with the touch panel 29 is displayed. This is because the user can easily confirm the associated functions. The mode change icon 28a indicates a position where the user touches when the association with the touch panel 29 is changed. That is, when the upper left of the touch panel 29 is touched, in the illustrated example, the mode is changed, and a pattern change screen as shown in FIG. 3B is displayed.

  FIG. 3E shows a display on the main body side display unit 6 after the association between the third pattern 6c and the zoom is completed. In this state, the selection function 6h and the bar display 6i are displayed together with the live view display. By observing the live view display, the user can determine the composition of the subject image and the photo opportunity. At this time, the function (zoom in the illustrated example) associated with the touch panel 29 can be confirmed from the selection function 6h. The type of the pattern selected from the bar display 6i can be confirmed, and the focal length can be known from the position of the shaded portion of the bar display 6i in the illustrated example.

  Next, the operation of the first embodiment of the present invention will be described using the flowcharts shown in FIGS. FIG. 4 is a flowchart showing the lens communication operation on the camera body 10 side. This operation is executed by the signal processing and control unit 1 according to a program stored in a memory (not shown).

  When the body side lens communication flow shown in FIG. 4 is entered, it is first determined whether or not the body side lens communication is possible (S1). Here, it is determined whether or not the lens barrel 20 is attached to the camera body by a lens attachment detection unit (not shown). If the lens barrel 20 is attached to the camera body as a result of this determination, it is determined whether or not communication with the control unit 21 in the lens barrel 20 is possible via the communication units 11 and 22. In addition, without providing a lens mounting detection unit, communication with the lens barrel 20 is always attempted, and when communication is impossible, it may be determined that the lens is not mounted, and when communication is possible, it is determined that the lens is mounted. Absent.

  If the result of determination in step S1 is that the lens barrel 20 is attached to the body and communication is possible, then the other party is confirmed (S3). Here, the type of the lens barrel attached is determined based on the communication result. The other party is specified based on the lens type information stored in the memory 27 of the lens barrel 20.

  Once the other party is confirmed, it is next determined whether setting is necessary (S5). Here, it is determined whether or not the touch panel 29 of the lens barrel 20 is associated with a function such as zoom. If the association has already been established, it is determined that the setting is not necessary. If the association has not been established, it is determined that the setting is necessary. In addition, after the association between the touch panel and the function is set, the lens barrel 20 may be removed and attached to another camera body. In this case, it is determined that setting is necessary in step S5.

  As a result of the determination in step S5, if it is determined that setting is necessary, then a lens specification request is made (S7). In the present embodiment, the lens barrel 20 is an interchangeable lens, and various lens barrels can be attached. Therefore, in this step, transmission of information related to the specifications of the attached lens barrel 20 is performed. 20 to request.

  When the lens specification is requested, the lens specification is received from the lens barrel 20 (S9). In step S37 of FIG. 5 described later, the lens barrel 20 transmits the lens specifications stored in the memory 27 to the camera body 10, and in this step, the transmitted lens specifications are received. In addition, since the operation images such as the first to fourth patterns as shown in FIG. 3B are received, the user selects one on the menu screen or the like.

  When the lens specification is received, the specification of the camera body is transmitted to the lens barrel 20 (S11). In the present embodiment, functions related to the camera body 10 such as exposure correction and mode change are associated on the touch panel on the lens barrel 20 side. Send.

  If the result of determination in step S5 is that setting is not necessary, then parameter designation is performed with the set content (S13). Since the function is already associated with the touch panel 29 when the lens barrel is mounted, there is no need for setting. When exposure correction or the like is set, parameters such as an exposure correction value are also set. In this case, the set parameters are transmitted to the lens barrel 20. If the camera is removed after being set in another camera body, as described above, it is determined that the setting is necessary in step S5. In this case, in step S13, it may be displayed on the main body side display unit 6 (or the lens side display unit 28) that the setting has been completed to warn the user. That is, in a camera that performs setting of the lens operation unit through communication between the lens and the camera, when the combination of the lens and the camera is changed, a warning display may be displayed on the camera that the setting has been completed.

  In step S13, if parameter setting is performed with the set contents, or body specification is transmitted in step S11, or if the result of determination in step S1 is that there is no lens mounting or communication, then whether or not the association mode is set. Is determined (S15). The association mode is executed when the lens barrel 20 is attached or by operating a menu screen or an operation member.

  If the result of determination in step S15 is that it is in association mode, association is next carried out (S17). Here, the operation image is displayed on the main body side display unit 6 in any of the first to fourth patterns 6a to 6d set in advance. For example, FIG. 6C is displayed when the third pattern 6c is set. When the operation image is displayed, the user performs association by performing a slide operation from the function icon 6f toward the selection pattern 6e on the lens side display unit 28 on the lens barrel 20 side.

  Subsequently, an operation parameter is instructed to the lens (S19). A range of parameters is required depending on the associated mode. For example, when the associated mode is the exposure correction mode, the exposure correction parameter range (for example, −3 to +3) is set. When the associated mode is the shutter speed priority mode, the shutter speed range (for example, 1 to 1/1 /) is set. 2000 sec) is transmitted to the lens barrel 20. The lens barrel 20 performs the received parameter instruction processing in steps S41 and S43 (see FIG. 5) described later.

  If an operation parameter is instructed to the lens in step S19 or if the result of determination in step S15 is not the association mode, it is next determined whether or not a parameter value change signal has been received (S21). When the user touches and changes the touch panel 29 of the lens barrel 20, the parameter value is transmitted to the camera body 10 side in step S55 (see FIG. 5) described later. Therefore, in step S21, it is determined whether or not a parameter value change signal has been received.

  If the result of determination in step S21 is that a parameter value change signal has been received, then parameters and their numerical values are set (S23). Here, the parameter transmitted from the lens barrel 20 and its numerical value are received, and the exposure correction value, the shutter speed in the shutter speed priority mode, and the like are set according to the received parameter.

  If the parameter and its value are set in step S23, or if the parameter value change signal is not received as a result of the determination in step S21, the body-side lens communication flow is terminated, and the body-side main flow (not shown) Return to.

  Next, the body communication operation on the lens barrel 20 side will be described using the flowchart shown in FIG. The operations of FIG. 5 and FIGS. 6 and 7 to be described later are executed by the control unit 21 in accordance with a program stored in the memory 27.

  When the flow of lens side body communication shown in FIG. 5 is entered, it is first determined whether the body is mounted and communication is possible (S31). Here, whether or not the lens barrel 20 is attached to the camera body 10 is determined by a body attachment detection unit (not shown). If the lens barrel 20 is attached to the camera body 10 as a result of this determination, it is determined whether communication with the signal processing and control unit 1 of the camera body 10 is possible via the communication units 11 and 22. . In addition, without providing the body attachment detection unit, communication with the camera body 10 is always attempted, and when communication is impossible, it may be determined that the body is not attached, and when communication is possible, it is determined that the body is attached. .

  If the result of determination in step S1 is that it is attached to the body and communication is possible, then the other party is confirmed (S3). Here, the type of the camera body 10 attached is determined based on the communication result. The other party is identified based on body type information stored in a memory (not shown) in the camera body 10.

  If the other party is confirmed in step S33 or if the result of determination in step S31 is not body mounting or communication, it is next determined whether or not there is a specification request (S35). In step S7 (see FIG. 4) described above, it is determined whether or not transmission of the specification of the lens barrel 20 is requested from the camera body 10 side to the lens barrel 20 side.

  If there is a specification request as a result of the determination in step S35, the lens specification is then transmitted to the camera body 10 (S37). Here, various data such as lens specifications stored in the memory 27, for example, a long focal length, a short focal length, an open aperture, optical characteristics, and the like are transmitted to the camera body 10 via the communication units 11 and 22. Send. In addition, operation images such as the first to fourth patterns as shown in FIG. 3B are transmitted. When the lens specification is transmitted, the camera body 10 receives the lens specification in step S9 (see FIG. 4) described above.

  Once the lens specification is transmitted, the body specification is received (S39). As described above, when the camera body 10 receives the lens specification, the body specification is transmitted to the lens barrel 20 in step S11. In this step, the body specification transmitted from the lens barrel 20 is received.

  If the body specification is received in step S39, it is next determined whether or not a parameter instruction is received (S41). In step S <b> 19 described above, operation parameters may be transmitted from the camera body 10. Therefore, in this step, it is determined whether or not an operation parameter has been received from the camera body 10.

  If the result of determination in step S41 is that a parameter instruction has been received, the result of associating operation coordinates with specifications and parameters is recorded (S43). Here, the association of parameters is determined from the operation coordinates (touch position on the touch panel 29) and specifications (for example, exposure correction, set shutter speed in the shutter speed priority mode, etc.) and recorded in the memory 27. For example, when the touch panel 29 is associated with being used for setting the exposure correction value, the relationship of the numerical value of the exposure correction according to the touch position is determined, and the result is recorded.

  In step S43, if the parameter association result is recorded from the operation coordinates and the specification, or if the result of determination in step S35 is that there is no specification request, or the result of determination in step S41 is that there is no parameter instruction, Next, it is determined whether or not a touch operation has been performed (S45). Here, based on the detection output of the touch panel 29, it is determined whether or not the user has performed a touch operation.

  If the result of determination in step S45 is that a touch operation has been made, it is next determined whether or not there is an enable signal from the body side (S47). Since the user may inadvertently touch the touch panel 29, an enable signal is output on the camera body 10 side when the user is in an operating state. Therefore, when the enable signal is not output from the camera body 10, the touch operation on the touch panel 29 is prohibited.

  If the result of determination in step S47 is that an enable signal has been output from the body side, it is next determined whether or not the processing related to the touch operation is on the body side (S49). In the case of zoom or manual focus (MF), processing is performed on the lens barrel 20 side. However, exposure correction and mode change require processing in the camera body 10.

  If the result of determination in step S49 is that the process is on the body side, then numerical calculation is performed (S53). Here, the numerical values of the parameters are calculated from the body specifications and the operation coordinates (S53). Here, according to the set mode (for example, exposure correction mode or shutter speed priority mode), the numerical value of the parameter corresponding to the setting mode is determined from the specification of the camera body 10 and the touch position (operation coordinates) on the touch panel 29. Is calculated. Detailed operation of this numerical calculation will be described later with reference to FIGS.

  Once the numerical value of the parameter has been calculated, the parameter and its value are then transmitted (S55). Here, the parameters calculated in step S53 and their numerical values are transmitted to the camera body 10. For example, the parameter is exposure correction, and -2 steps are transmitted to the camera body 10 as the numerical value. When receiving the parameters and numerical values, the camera body 10 sets the parameters and their values in step S23 (see FIG. 4).

  If the result of determination in step S49 is that the process is on the lens barrel side, the drive amount is calculated from the operation coordinates and specifications (S51). When processing is performed on the side of the lens barrel 20 such as zoom or manual focus, the driving amount is calculated from the touch position (operation coordinates) of the touch panel 29 and the specifications of the lens barrel 20. For example, when the zoom mode is set, the driving amount of the photographing lens 26 corresponding to the touch position and the slide direction is calculated for zooming.

  If the parameter is calculated from the operation coordinates and specifications in step S51, or if the parameter and its value are transmitted in step S55, or if the result of determination in step S47 is that the enable signal has not been output from the body side, or If the result of determination in step S <b> 45 is that there has been no touch operation, lens side body communication is terminated and processing returns to the main flow (not shown).

  Next, detailed operation of the numerical calculation in step S53 will be described with reference to FIGS. In the numerical value calculation flow, it is first determined whether or not the exposure correction mode is associated with the operation of the touch panel 29 (S61).

  If the result of determination in step S61 is that exposure correction has been associated, then the correction is changed according to change in operation position and time (S61). Here, the exposure correction value is changed based on the touch start position of the touch panel 29, the slide direction, the touch end position, the touch time, and the like. For example, when the third pattern 6c is selected, when the user's touch direction slides to the right, the exposure correction value is increased, while when the touch direction slides to the left Decrease the exposure compensation value. When the first or second pattern 6a, 6b is selected, the exposure correction value is increased or decreased according to the touch position and the touch time.

  Once the correction value has been changed in step S63, it is next determined whether or not the limit has been exceeded (S65). Here, it is determined whether or not the correction value changed in step S63 exceeds the limit of the exposure correction value range. This is because the exposure correction value that can be changed is limited to a predetermined value range.

  If the result of determination in step S65 is that the limit has not been exceeded, a setting correction value is set (S67). Here, the exposure correction changed in step S63 is set. On the other hand, if the result of determination is that the limit has been exceeded, a limit correction value is set (S69). Here, the limit value of the exposure correction value is set.

  If the result of determination in step S61 is not exposure correction, it is next determined whether or not the shutter speed priority (SS) mode is in effect (S71). In the shutter speed priority mode, a shutter speed in a shutter (not shown) in the camera body 10 is set in advance, and an aperture (not shown) in the lens barrel 20 is set so as to achieve appropriate exposure with respect to the set shutter speed. This is an exposure control mode for controlling. Since the shutter speed priority mode is set in the camera body 10, if the shutter speed priority mode is set, it is received as one of the specifications of the camera body 10 in step S39 (see FIG. 5). To do.

  If the result of determination in step S71 is that shutter speed priority mode has been set, next, the shutter speed (SS) is changed according to the operation position and time (S73). Here, the shutter speed value is changed based on the touch position of the touch panel 29, the slide direction, the touch time, and the like. For example, when the third pattern 6c is selected, when the user's touch direction slides to the right, the shutter speed is changed to the high speed side, while the touch direction slides to the left Change to the low speed side.

  Once the shutter speed value has been changed in step S73, it is next determined whether or not the limit has been exceeded (S65). Here, it is determined whether or not the shutter speed value changed in step S73 exceeds the limit of the control range. This is because the shutter speed that can be changed is limited to a predetermined shutter speed range.

  If the result of determination in step S75 is that the limit has not been exceeded, the set shutter speed (SS) is set (S77). Here, the shutter speed (setting SS) changed in step S73 is set. On the other hand, if the result of determination is that the limit has been exceeded, the limit shutter speed (limit SS) is set (S79). Here, the limit value of the shutter speed value is set.

  When the correction value is set in steps S67 and S69, or when the shutter speed value is set in steps S77 and S79, the process returns to the original flow.

  If it is determined in step S71 that the mode is not the shutter speed priority mode, it is next determined whether or not the mode is 1 (S81). Steps S81 to S91 are processes when the multi-recording mode is selected as the mode. Multi-recording in the present embodiment refers to a recording method in which an image on the entire screen and an image in a specified range are recorded simultaneously. This is a case where multi-recording, which is one of the function icons 6f in FIG. Note that “mode” may be provided as one of the modes in the function icon 6f in FIG.

  If the result of determination in step S81 is mode 1, then selection mode 1 information is displayed (S83). Here, an operation image for switching the multi-recording as shown in FIG. 8A is transmitted to the camera body 10 and displayed on the body-side display unit 6. In the illustrated example, “range”, “horizontal”, “vertical”, and “optical zoom” are displayed on the ring. “Range” is a mode for changing the size of the specified range, “Horizontal” is a mode for moving the position of the specified range to the left and right, and “Vertical” is the size. This is a mode for moving the position of the specified range up and down.

  If the selection mode 1 information is displayed, next, rotation amount information corresponding to the mode is detected (S85). Here, as shown in FIGS. 8A, 8 </ b> C, and 8 </ b> E, the “range”, “horizontal”, and “vertical” are sequentially moved on the touch panel 29 according to the rotation direction of the user's touch.

  If the result of determination in step S81 is not mode 1, it is determined whether or not it is mode 2 (S87). Here, as shown in FIGS. 8A, 8 </ b> C, and 8 </ b> E, determination is made based on whether “range”, “horizontal”, or “vertical” is determined. In mode 2, the designated range is determined according to the operation method in mode 1.

  If the result of determination in step S87 is mode 2, next, selection mode N information is displayed (S89). Here, as shown in FIGS. 8B, 8 </ b> D, and 8 </ b> F, a selection range (displayed with a broken line) centered on the detected face is displayed on the main body side display unit 6 on the camera main body 10 side.

  Once the selection mode N information is displayed, rotation amount information corresponding to the mode is detected (S91). Here, the rotation direction and the rotation amount of the user's touch are detected on the touch panel 29, and the “range” is sequentially changed as shown in FIGS. 8A, 8C, and 8E according to the direction and the amount. In addition, it is moved to “horizontal” and “vertical”.

  That is, when “range” is selected, as shown in FIG. 8B, the size of the selection range (broken line) is changed according to the rotation amount. If “horizontal” is selected, as shown in FIG. 8D, the position of the selection range (broken line) is moved to the left and right according to the amount of rotation. When “vertical” is selected, as shown in FIG. 8F, the position of the selection range (broken line) is moved up and down according to the amount of rotation.

  If the rotation amount information corresponding to the mode is detected in steps S85 and S91, or if the result of determination in step S87 is not mode 2, the parameter calculation is terminated and the original flow is returned to.

  As described above, in the first embodiment of the present invention, the display pattern (first pattern 6a to fourth pattern) is displayed on the main body side display unit 6, and the touch panel 29 provided on the lens barrel 20 is displayed. By touching, the display pattern is associated with the camera body function or the lens barrel function. Therefore, while looking at the display pattern displayed on the main body display unit 6, for example, the button display pattern (first pattern 6a, second pattern 6b) or the bar display pattern (third pattern 6c, fourth pattern 6d). By performing a touch operation on the touch panel 29 according to this pattern, the zooming of the lens barrel function and the manual focusing function are associated, the camera body function exposure correction, the shutter speed priority mode, and the multi-recording function are associated. It becomes possible to do.

  The lens barrel 20 also has a lens-side display unit 28 that displays a selected display pattern among a plurality of display patterns, and a touch panel 29 that is provided on the lens-side display unit 28 and detects a touch state on the display pattern. have. For this reason, also on the lens barrel 20 side, when touching, the state of the lens can be easily confirmed.

  Further, the body specification is transmitted from the camera body 10 to the lens barrel 20 (S11 in FIG. 4), and the operation parameter is transmitted (S19 in FIG. 4). The lens barrel 20 controls the camera body 10. When such a function is associated (S49 in FIG. 5), the control unit 21 calculates numerical values of parameters such as an exposure correction value and a shutter speed that are changed according to the touch state (S53 in FIG. 5). Are transmitted to the camera body 10 (S55 in FIG. 5). For this reason, even in the case of a function controlled on the camera body side such as exposure correction, the user can change the exposure correction value by operating on the touch panel 29 provided in the lens barrel 20. The exposure compensation value can be changed while observing the live view display. In addition, the control part 21 functions as a calculation part which calculates the numerical value of a parameter according to the set function, when the function linked | related with the touch detection part is a function by the side of a camera main body. Further, the communication unit 22 functions as a communication unit that transmits the numerical values of the parameters calculated by the calculation unit to the camera body.

For example, zooming operation, manual focus, exposure correction, or the like is performed according to a touch operation on the touch panel 29, or a function is assigned according to the user's intention.

  The lens operation determination unit 1 b determines the touch operation state of the touch panel 29 on the lens barrel 20 via the communication unit 22 and the communication unit 14. When a button icon is touched on the touch panel 29 or a slide operation is performed between two icons, these states are determined.

  The touch position determination unit 1c inputs a detection signal from the touch panel 7 on the camera body 10 side, and determines which position on the screen of the body side display unit 6 the user has touched. Further, based on the detection signal of the touch panel 29 transmitted from the lens barrel 20, it is determined which position on the lens side display unit 28 the user touches (including slide). The lens barrel 20 may transmit coordinate information of the touch position on the touch panel 29.

  The display control unit 1 d controls display on the main body side display unit 6. The display control unit 1d performs various display controls such as live view display. As one of the display controls, the display control unit 1d performs display control during the lens operation association operation. That is, when the operation image is transmitted from the lens barrel 20, it is displayed on the main body side display unit 6.

  The lens operation association unit 1a, the lens operation determination unit 1b, the touch position determination unit 1c, the display control unit 1d, and the like in the signal processing and control unit 1 function as a lens association unit.

Located in the vicinity. The image sensor 2 converts the subject image into an image signal. This image signal is AD converted into digital image data, and then output to the signal processing and control unit 1. The photographing lens 26 and the image sensor 2 described above function as an imaging unit that converts a subject image formed by the photographing optical system into an electrical signal.

  The face detection unit 3 receives image data of a subject image and detects a face such as a person. The face detected by the face detection unit 3 may be focused. In FIG. 1, although the focus detection circuit is omitted, a contrast signal is obtained from the image data, and a known contrast AF for controlling the photographing lens 26 so that the contrast signal reaches a peak, or a phase difference is used. What is necessary is just to employ | adopt suitably, such as well-known phase difference AF which calculates | requires a focus amount, and controls the photographic lens 26. FIG.

  The recording unit 4 is a recording medium such as a flash memory, and records still image data or moving image data for recording based on image data from the image sensor 2. When the reproduction mode is selected, the recorded image data is read and displayed on the main body side display unit 6.

  The communication unit 12 performs communication with an eyepiece finder 30 described later. In the present embodiment, as described above, the eyepiece finder 30 can be attached to the camera body 10, and when the request signal is output from the signal processing and control unit 1 at the time of attachment or the communication unit in the eyepiece finder 30. Communication with 32 is performed.

  The main body side display unit 6 includes a display such as an LCD (Liquid Crystal Display), an organic EL, and the like disposed on the back surface of the camera main body 10. The main body side display unit 6 performs live view based on the image data from the image sensor 2 and displays an image recorded in the recording unit 4 during reproduction. When the lens is associated with the function of the touch panel 29 and the lens barrel 20 or the camera body 10, the first pattern 6a to the fourth pattern 6d (see FIG. 10) and icons representing the functions are displayed.

  The touch panel 7 is configured integrally with the front surface of the main body side display unit 6 or the main body side display unit 6, and outputs a detection signal to the signal processing and control unit 1 according to the position where the user touches the main body side display unit 6. . The touch panel 7 can perform touch input of a screen in various camera settings. In addition, at the time of lens association operation between the touch panel 29 on the lens barrel 20 side and the function, touch detection is not performed, and the association operation is prohibited. However, it is of course possible to enable the association operation on the camera body 10 side.

  The operation determination unit 8 determines operation states of various operation members of the camera body 10 such as a power button, a release button, a playback button, a menu button, and the like. The signal processing and control unit 1 executes various controls based on the operation state of the operation member determined by the operation determination unit 8.

  The eyepiece finder 30 is provided with an eyepiece display unit 31 and a communication unit 32. The communication unit 32 communicates with the communication unit 5 on the camera body 10 side. The eyepiece display unit 31 has an electronic viewfinder and displays an image input via the communication unit 5 and the communication unit 32. For example, live view display is performed based on image data from the image sensor 2. The eyepiece display unit 31 may also function as a display unit that displays a subject image based on an electrical signal from the imaging unit.

  Next, setting of the operation method in the present embodiment will be described with reference to FIG. 10 (a), (b), (d), and (e) are the same as FIGS. 3 (a), (b), (d), and (e) in the first embodiment, and detailed description thereof is omitted.

  FIG. 10C shows the display on the main body side display unit 6 when the third pattern 6c is set, as in the case of the first embodiment. In the first embodiment, five functions of zoom, manual focus (MF), exposure correction, shutter speed priority mode (SS), and multi-recording mode are displayed as the function icon 6f. On the other hand, in the second embodiment, four types of functions of zoom, manual focus (MF), exposure correction, and mode change are displayed. Of course, as in the first embodiment, function icons may be omitted or added as appropriate.

  In the present embodiment, as in the first embodiment, when an operation image as shown in FIG. 10 (c) is displayed, the user looks at the operation image and adds the function desired by the user to this pattern. In the case of association, an association operation can be performed on the touch panel 29 on the lens barrel 20 side. For example, when the user wants to perform zooming by operating the touch panel 29, the position on the touch panel 29 corresponding to the “zoom” of the function icon 6f (upper right) is directed to the position corresponding to the selection pattern 6e (middle left). To perform a sliding operation. With this slide operation, zooming can be performed by performing a slide operation on the touch panel 29.

  FIG. 10F shows an example of display on the main body side display unit 6 when the fourth pattern 6d is selected. When the fourth pattern 6d is selected, zooming can be performed by the user sliding the left side of the touch panel 29 in the vertical direction, and focusing can be performed by sliding the right side in the vertical direction. Can do. Correspondingly, a zoom bar display 6j is displayed on the left side of the main body side display unit 6 and a focus bar display 6k is displayed on the right side together with the live view display.

  Next, the operation of the second embodiment of the present invention will be described with reference to the flowcharts shown in FIGS. 11 to 14 and FIG. FIG. 11 is a flowchart showing the camera control operation of the camera body 10. This operation is executed by the signal processing and control unit 1 according to a program stored in a memory (not shown).

  If the camera control flow shown in FIG. 11 is entered, it is first determined whether or not the lens has been replaced (S101). Here, as in the first embodiment, it is determined whether or not the lens barrel 20 has changed from the unmounted state to the mounted state on the camera body based on the detection output of a lens mounting detection unit (not shown). As in the case of the first embodiment, communication with the lens barrel 20 is always attempted without providing a lens mounting detection unit, and it is determined whether or not a lens has been replaced based on the communication result. It doesn't matter.

  If the result of determination in step S101 is that the lens has been replaced, it is next determined whether or not the lens can be changed by the operating member (S103). Here, communication is performed with the control unit 21 in the lens barrel 20 via the communication units 11 and 22 to acquire lens type information, and based on this, it is determined whether or not the lens can be changed by the operating member. Depending on the attached lens barrel, the touch panel 29 or the like may not have a member for lens association. In this step, it is determined whether or not the lens barrel 20 is capable of associating functions with the touch panel 29 as shown in FIG.

  If the result of determination in step S103 is that the operating member can be changed, next, displayable pattern communication is performed (S105). Here, the first pattern 6a to the fourth pattern 6d set on the camera body 10 side are transmitted to the control unit 21 on the lens barrel 20 side via the communication units 11 and 22.

  Once displayable pattern communication is performed, an associating operation is then performed (S107). Here, as shown in FIG. 10C, the selection pattern 6e of the touch panel 29 is associated with the function icon 6f of the lens barrel 20 or the camera body 10. Details of this association operation will be described later with reference to FIG.

  Once the association operation has been performed, it is next determined whether or not it is a shooting mode (S109). Here, it is determined whether or not a shooting mode for acquiring and recording image data from the image sensor 2 is set.

  If the result of determination in step S109 is that the shooting mode has not been set, it is next determined whether or not it is in playback mode (S111). Since the reproduction mode is set by operating an operation member such as a reproduction button, in this step, determination is made based on the detection result of the operation determination unit 8.

  If the result of determination in step S111 is that playback mode has been set, image playback mode is next executed (S113). Here, the image data recorded in the recording unit 4 is read out, subjected to expansion processing in the signal processing control unit 1, and then reproduced and displayed on the display unit 6. When image reproduction is performed in step S113, or if the result of determination in step S111 is that the reproduction mode has not been reached, processing returns to step S101.

  If the result of determination in step S109 is that it is shooting mode, then imaging and image display are started (S115). Here, an image signal is acquired by the imaging device 2, image processing is performed in the signal processing and control unit 1, and live view display is performed on the main body side display unit 6. In this live view display, as shown in FIGS. 10E and 10F, the pattern and the selection function 6h are superimposed on the live view display.

  Next, lens communication is performed (S117). Here, various information such as an operation state of the touch panel 29, unique information of the lens barrel 20, current focal length information, current focal position information, aperture state, and the like via the lens barrel 20 and the communication units 11 and 22 are used. And the information is received from the lens barrel 20. Also, various camera information such as camera specifications is transmitted.

  Once lens communication has been carried out, it is next determined whether or not there is a display update request through lens touch panel operation (S119). When the user touches the touch panel 29 of the lens barrel 20, a display update request is transmitted in step S217 (see FIG. 14) 117 described later. In this step, determination is made based on whether or not this display update request has been received.

  If the result of determination in step S119 is that there is a display update request, display update is next performed (S121). Here, the display of the main body side display unit 6 is updated in response to the operation of the touch panel 29 on the lens barrel 20 side. For example, when the third pattern 6c is selected and the user performs a left / right slide operation on the touch panel 29, the focal length is changed according to this movement, and the focal length position on the bar display is changed.

  If display update has been performed or if the result of determination in step S119 is that there has been no display update request, it is next determined whether or not shooting has been performed (S123). When the user determines the composition and operates the shutter button, shooting is performed. In this step, the determination is made based on whether or not the shutter button has been pressed based on the detection result of the operation determination unit 8.

  If the result of determination in step S123 is shooting, shooting and recording are next carried out (S125). Here, the signal processing and control unit 1 processes the image signal from the image sensor 2 and records the processed image data in the recording unit 4.

  If shooting and recording have been performed, or if the result of determination in step S123 is that shooting has not been performed, it is next determined whether or not a function change operation has been performed (S127). When the pattern is changed as shown in FIG. 10B, or when the association is changed as shown in FIG. 10C, a function change operation is performed. This function change operation is performed on the menu screen of the camera body 10 or the like.

  If the result of determination in step S127 is that there is no function change operation, processing returns to step S101. On the other hand, when a function change operation is performed, a lens function change request is transmitted to the lens barrel (S129). If a change request is transmitted, it will return to step S103 and will associate the selection pattern 6e and the function icon 6f as shown in FIG.10 (b).

  As described above, in the camera control according to the present embodiment, when a lens is exchanged (S101) or when a function change operation is performed (S127), an association between a pattern (selection pattern 6e) and a function (function icon 6f) is established. (S107). When the shooting mode is set, as shown in FIGS. 10E and 10F, an image for an association operation is superimposed on the live view display for display. Further, lens communication is performed between the camera body 10 and the lens barrel 20 (S117), and when there is a display update request, the display on the body side display unit 6 is changed according to the operation state of the touch panel 29. (S121).

  Next, detailed operation of the association operation in step S107 will be described with reference to FIG. In the flow of the association operation, first, it is determined whether or not there is lens association reception (S151). Since the lens association operation is performed by touching the touch panel 29 on the lens barrel 20 side when the lens is replaced, in this step, whether or not a lens association request has been received via the communication units 22 and 11 is determined. judge.

  If the result of determination in step S151 is that lens association has not been received, default association is carried out (179). When the lens related information cannot be received, the zoom function is associated with a predetermined default, for example, the selection pattern 6e.

  If the result of determination in step S151 is that lens association has been received, then lens association display is performed (S153). When performing the lens association operation, an operation unit image for association operation as shown in FIG. 10C is transmitted from the lens barrel 20, so that the received operation unit image is displayed on the main body side display unit 6. indicate. The generation and transmission of the operation unit image on the lens barrel 20 side will be described later with reference to FIG.

  Once the lens association display has been carried out, it is next determined whether or not a slide is detected (S155). Since the detection result of the touch state of the touch panel 29 is transmitted via the communication units 11 and 22, the touch position determination unit 1c determines whether or not the slide operation has been performed based on the detection result.

  If the result of determination in step S155 is that no slide has been detected, then a standby state is entered for a predetermined time (S157), and steps S155 and S157 are executed alternately until the predetermined time has elapsed. In the lens association operation, as shown in FIG. 10C, either the selection pattern 6e or the function icon 6f is associated by a slide operation. In steps S155 and S157, it is detected for a predetermined time whether or not this slide operation has been performed.

  If the result of determination in step S155 is that there has been slide detection, it is next determined whether or not the slide start point / end point is on the image operation section (S159). Here, the touch position determination unit 1c determines whether the start point or the end point of the slide operation on the touch panel 29 is the operation unit (selection pattern 6e) based on the position detection result of the touch panel 29.

  If the result of determination in step S159 is that the slide start point and end point are in the image operation section, it is next determined whether or not the slide start point end point is in the icon section (S161). Here, the touch position determination unit 1c determines whether the start point or the end point of the slide operation on the touch panel 29 is the icon part (function icon 6f) based on the position detection result of the touch panel 29.

  If the result of determination in step S161 is that the slide start point / end point is an icon part, it is next determined whether or not multiple associations are possible (S163). The fourth pattern 6d can associate two functions, and the first pattern 6a, the second pattern 6b, and the third pattern 6c can associate only one function. In this step, it is determined whether or not a plurality of patterns can be associated according to the pattern type.

  If the result of determination in step S163 is that multiple associations are possible, it is next determined whether or not there is a free space for association (S165). Even in a pattern in which two functions can be associated, there are cases where two functions are already associated. Therefore, in this step, it is determined whether or not there is an association space.

  As a result of the determination in step S157, if a predetermined time has elapsed, or if the result of determination in steps S159 to S165 is No, an already associated item (function) is displayed (S173). Here, when a plurality of functions are associated, a plurality of functions are displayed, and when one function is associated, the functions are displayed on the main body side display unit 6.

  Subsequently, it is determined whether or not to delete the association (S175). When the user deletes the association, a new association can be performed. Deletion is performed by displaying another screen for deletion on the display unit 6 on the main body and by operating a delete button or a deletion icon provided on the camera main body 10. In this step, the function icon is selected and deleted. The determination is made based on whether or not a button or a deletion icon is operated.

  As a result of the determination in step S175, if the association is to be deleted, the selected association is deleted (S177). When the deletion is executed, the process returns to step S155, and the selection pattern 6e and the function icon 6f can be associated again.

  If the result of determination in step S165 is that there is no association, the operation unit (selection pattern 6e) and the icon function (function icon 6f) are then associated (S167). Since there is a free space for association, the association is executed.

  Once the association is performed, the association information is then transmitted (S169). Here, the result of one or a plurality of associations is transmitted to the control unit 21 of the lens barrel 20 via the communication units 11 and 22.

  If the association information is transmitted in step S169, or if the association is not deleted as a result of the determination in step S175, or if the default association is made in step S179, it is next determined whether or not to end the association operation. (S171). When the user ends the association operation, the user clicks the end icon 6g on the association operation screen shown in FIG. Therefore, in this step, the determination is made based on whether or not the end icon 6g is clicked.

  If the result of determination in step S171 is that the association operation has not ended, processing returns to step S155. On the other hand, as a result of the determination, when the association operation is terminated, this flow is terminated and the original flow is returned.

  Next, the operation unit image communication executed in the lens barrel 20 will be described with reference to FIG. The operation unit image is an image that the camera body 10 receives from the lens barrel 20 in step S105 (see FIG. 11), and is an operation image for performing a lens association operation as shown in FIG. is there. 13, 14, and 16 are executed by the control unit 21 in the lens barrel 20 according to a program stored in the memory 27.

  When the operation unit image communication flow is entered, it is first determined whether or not lens replacement has been performed (S181). Here, as in the first embodiment, a body mounting detection unit (not shown) determines whether or not the lens barrel 20 is mounted on the camera body 10 from the unmounted state. Instead of providing the body mounting detection unit, communication with the camera body 10 is always attempted, and when the communication is changed from impossible to possible, it may be determined that the lens has been replaced.

  If the result of determination in step S181 is that the lens has been replaced, it is next determined whether or not communication is possible (S183). Here, it is determined whether communication with the signal processing and control unit 1 of the camera body 10 is possible via the communication units 11 and 22.

  If the result of determination in step S183 is that communication is possible, then operation unit image transmission is performed (S185). Here, the images of the first pattern 6 a to the fourth pattern 6 d as shown in FIG. 10B are transmitted to the signal processing and control unit 1 of the camera body 10 via the communication units 22 and 11. The camera body 10 can select a pattern based on the received operation unit image.

  Subsequently, the in-lens memory is transmitted in association (S187). The in-lens memory 27 stores a selection pattern 6e and a selected function icon 6f for association. The control unit 21 reads these association information from the memory 27 and transmits the information to the signal processing and control unit 1 of the camera body 10 via the communication units 22 and 11.

  If the association of the in-lens memory is transmitted, it is next determined whether there is a change request (S189). In steps S127 and S129 (see FIG. 11), if there is a change request on the camera body 10 side, a change request signal is transmitted to the lens barrel 20 side. In this step, determination is made based on whether a change request has been received.

  If the result of determination in step S189 is that there is a change request, it is next determined whether or not association information has been received (S191). Here, it is determined whether information relating to association, such as a pattern change or a mode change, has been received from the camera body 10 side.

  If the association information is received as a result of the determination in step S191, the touch panel function is changed from the association information (S193). Here, the function of the touch panel 29 is changed according to the received association information. For example, when the third pattern 6c is changed to the fourth pattern 6d, the touch detection area is changed according to the pattern. Further, since there is a possibility that the lens barrel 20 is held during the pattern change, the detection of the touch operation on the touch panel 29 is invalidated during the change period.

  Subsequently, the association is reflected in the in-lens memory (S195). The association information stored in the memory 27 is updated according to the function change performed in step S193. Next time, in step 187, when the association of the in-lens memory 27 is transmitted, this content is transmitted.

  If the association is reflected in the in-lens memory in step S195, or if the result of determination in steps S181, S183, S189, S191 is No, the flow of the operation unit image communication is terminated, and the lens barrel 20 Return to the main flow (not shown).

  Next, lens operation in the lens barrel 20 will be described with reference to FIG. When the lens operation flow is entered, first, an operation unit image is displayed (S201). Here, as shown in FIG. 10D, an operation unit image corresponding to the selected pattern is displayed on the lens side display unit 28.

  When the operation unit image is displayed, it is next determined whether or not there is a display mode change request (S203). In steps S127 and S129 (see FIG. 11), if there is a pattern change request on the camera body 10 side, a change request signal is transmitted to the lens barrel 20 side. In this step, determination is made based on whether a change request has been received.

  If the result of determination in step S203 is that there is a display mode change request, it is next determined whether or not there are multiple associations (S205). If the result of this determination is that there are a plurality of association patterns for which a change request has been made, the association function is changed (S207). For example, a display mode change request for changing any one of the first, second, and fourth patterns can be handled, but a change from the above pattern to the third pattern cannot be handled.

  If the result of determination in step S205 is that there are multiple associations, the association function is changed (S207). Here, when the pattern is changed to a plurality of associations, the function assignment is changed to bar display or button display.

  Once the association function is changed, association information is transmitted (S209). Here, the result of the association function change performed in step S207 is transmitted to the signal processing and control unit 1 on the camera body 10 side through the communication units 22 and 11.

  Once the association information has been transmitted, the lens display is updated (S211). Here, the display on the lens side display unit 28 is changed according to the association function change performed in step S207. Since the pattern has been changed, the display is made according to this change.

  If the lens display is updated or if the result of determination in step S205 is that there is no multiple association, processing returns to step S203.

  If the result of determination in step S203 is not a display mode change request, it is next determined whether or not there is an operation section operation (S213). Here, it is determined whether or not a touch operation has been performed on the touch panel 29.

  If the result of determination in step S213 is that there is an operation, then parameter conversion is performed (S215). Here, parameter conversion is performed in accordance with the position change of the touch operation. For example, when zoom is set as a function and a sliding operation is performed by touch, the zooming driving direction and driving amount are calculated from the start point and end point positions. If exposure correction is set, the exposure correction amount is calculated from the start and end positions of the slide operation. The method of parameter conversion will be described later with reference to FIG.

  Once parameter conversion has been performed, next, display update communication is performed (S217). Here, in order to display on the main body side display unit 6 on the camera main body 10 side, the association information is transmitted via the communication units 22 and 11.

  Once the display update communication is performed, the lens display is updated (S219). Here, the display on the lens side display unit 28 is updated in accordance with the parameter conversion in step S215.

  Once the lens display is updated, it is next determined whether or not the change target is the body side (S221). In this embodiment, zoom and manual focus (MF) are controlled on the lens barrel 20 side, but exposure correction and mode change are performed on the camera body 10 side. In this step, it is determined whether the object to be changed by the touch operation on the touch panel 29 is the camera body 10 side.

  If the result of determination in step S221 is that the target is on the body side, parameter numerical values are transmitted (S221). Here, the parameter value calculated in S215 is transmitted to the camera body 10. On the other hand, if the result of determination in step S221 is that the target is not on the body side, lens control is performed (S223). Here, the control unit 21 in the lens barrel 20 performs control according to the parameter value calculated in step S215.

  When the parameter numerical value is transmitted in step S221, or when the lens control is performed in S223, or if the result of determination in step S213 is that there is no operation unit operation, the lens operation flow is terminated, and the lens barrel 20 main Return to the flow (not shown).

  Next, parameter conversion in step S215 will be described with reference to FIG. In the vertical column of FIG. 15, the first pattern 6 a to the fourth pattern 4 are shown. In the case of the first pattern, as shown in FIG. 10A, the icons of the two buttons 1 and 2 are displayed on the left and right. In the case of the first pattern, the pasting mode is “**”, and “−10” is set as a numerical value when the time during which the button 1 is touched is “button 1 push time”. When the time during which the button 2 is touched is “the push time of the button 2”, “+10” is set as a numerical value. In the case of the third pattern, the pasting mode is “**”, “−10” is set when the coordinate 1 is touched, and “+10” is set when the coordinate 2 is touched. Is set.

  Next, lens communication in the lens barrel 20 will be described with reference to FIG. If the flow of continuous communication is entered, first the lens state is determined (S231). Here, the touch position detection unit 1 c detects the operation state of the touch panel 29. Further, various lens states such as the lens position in the lens barrel 20, the aperture diameter, and the rotation state of the ring operation unit 23a are determined by the position detection units 25a and 25b, the ring operation unit 23a, the lens operation unit 23b, and the like.

  Once the lens state is determined, it is next determined whether or not a lens control operation has been performed (S233). Here, it is determined whether the lens control is performed by a touch operation on the touch panel 29. For example, when the touch panel 29 is associated with zoom in the third pattern 6b, if a slide operation is performed on the touch panel 29, it is determined as a lens control operation. If the result of determination in step S233 is lens control operation, lens control is performed (S235). Here, control based on the touch state of the touch panel 29 is performed.

  If lens control is performed in step S235 or if the result of determination in step S233 is that the lens control operation has not been performed, it is next determined whether or not communication is being performed (S237). In steps S105 and S111 (see FIG. 11), since communication is performed on the camera body 10 side, communication is also performed on the lens barrel 20 side in response to the communication request at this time.

  If the result of determination in step S237 is communication, then lens state communication is performed (S239). Here, the state of the lens barrel 20 is transmitted in response to a request from the camera body 10. When the lens state communication is performed, lens control is performed (S241). Here, when an instruction regarding lens control is given from the camera body 10 side by lens communication, control corresponding to this is performed. For example, when an AF control instruction is issued from the camera body 10, control such as focusing is performed according to the AF control instruction.

  If lens control is performed in step S241 or if communication is not performed as a result of determination in step S237, the lens communication flow is terminated, and the original main flow is restored.

  Thus, in lens communication, control according to the lens state is performed, and when a control signal is received from the camera body 10, control according to the control signal is performed.

  Next, the exchange of signals between the camera body 10 and the lens barrel 20 will be described with reference to FIG. FIG. 17A shows signal exchange when a function is associated with the touch panel 29. First, at time T1, when the lens barrel 20 is mounted on the camera body 10 (S101 in FIG. 11, S181 in FIG. 13) or a function change request (see S129 in FIG. 11) is made at time T1, at time T2. The lens barrel 20 transmits an operation unit image (lens image) (see S185 in FIG. 13). Upon receiving the operation unit image, the camera body 10 displays the operation unit image at time T3 (see S105 in FIG. 11).

  When the user performs the association operation as described with reference to FIG. 10, first, the touch signal 1 corresponding to the touch start point is transmitted from the lens barrel 20 to the camera body 10 at time T4, and the touch end point at time T5. The touch signal 2 corresponding to this is transmitted from the lens barrel 20 to the camera body 10. Here, the reason why the touch signals 1 and 2 are transmitted to the camera body 10 is to notify the association operation from the lens barrel 20 side to the camera body 10 side. As a result, an in-operation signal is transmitted to the signal processing and control unit 1 on the camera body 10 side, and it is possible to prevent unexpected control and the like in the lens barrel 20 and the camera body 10. It is also an important signal to prevent malfunction during operation. At time T6, the function is associated with the touch panel 29, and the association information is transmitted to the lens barrel 20 (S107 in FIG. 11 and S169 in FIG. 12).

  In the present embodiment, the slide determination is performed on the camera body 10 side, but the slide determination may be performed on the lens barrel 20 side. In this case, since information on the start point and end point of the slide is required, it is possible to omit sending information on the position where the touch is started and the position where the touch is finished to the camera body 10 side. When slide determination is performed on the lens barrel 20 side, the result may be sent to the camera body 10.

FIG. 17B shows signal exchange during lens operation. At time T11, the camera body 10 makes a communication request to the lens barrel 20 (see S117 in FIG. 11). At time T12, in response to the communication request, the lens barrel 20 performs lens state communication including exchange of the mode and parameter numerical values (see S117 in FIG. 11). At time T13, the camera body 10 has a corresponding function. Is switched (see S121 in FIG. 11). Similar operations are repeated at times T14 to T16 and times T17 to T19. Note that FIG.
In (a) and (b), communication is started from the camera body 10 side (see T1 and T11). However, the present invention is not limited to this, and it is of course possible to start communication from the lens barrel 20 side. .

  Next, details of synchronous communication performed between the camera body 10 and the lens barrel 20 in step S117 (see FIG. 11) and the like will be described using the timing chart shown in FIG. In FIG. 18, the horizontal axis represents the flow of time, and the vertical axis represents each processing content and timing. In the camera body process, in process B1, a live view image is displayed and an AF evaluation value is calculated based on the image data acquired in the previous frame. In the process B2, AF calculation, various setting changes, and the like are performed based on the lens state data acquired by the lens state communication.

  The vertical synchronization signal is a signal output corresponding to each frame. In imaging / reading, a subject image is picked up by the image pickup device 2 and the picked-up image data is read out. In FIG. 18, the image pickup / readout has a rhombus shape. In this embodiment, a rolling shutter is used when a live view image is acquired, and image pickup and read out are sequentially performed for each pixel line. To do.

  In the communication BL in the lens communication, a lens state data request command is transmitted from the camera body 10 to the lens barrel 20, and this command requests transmission of data indicating the lens state of the lens barrel 20 to the camera body 10. In the communication LB, the lens barrel 20 transmits data indicating the lens state to the camera body 10 in response to the lens state data request command.

  The lens communication synchronization signal is generated in response to the vertical synchronization signal in the camera body 10, and this lens communication synchronization signal is output from the synchronization signal terminal of the communication unit 11 of the camera body 10 to the lens barrel 20. The state of the lens position acquisition signal changes at a predetermined timing, for example, in the example shown in FIG. 18, when a substantially central time point of the charge accumulation time in the image sensor 2 has elapsed.

  Further, the process L1 in the lens barrel 20 acquires the position information of the focus adjustment lens in the photographing lens 26 at the state change timing of the lens position acquisition signal, and the ring operation unit 23a at the reception timing of the lens communication synchronization signal. This is a process for detecting the operation state. The process L2 is a process of transmitting lens state data such as the position information of the focus adjustment lens and the operation state of the ring operation unit 23a in accordance with the lens state data request command received from the camera body 10.

  As shown in the timing chart of FIG. 18, in the synchronous communication in this embodiment, the process B1 is executed in the camera body 10 in synchronization with the vertical synchronization signal, and the lens communication synchronization signal is synchronized with the vertical synchronization signal. It transmits to the lens barrel 20.

  When processing B1 is processed in the camera body 10, a lens state data request command is transmitted to the lens barrel 20 by communication BL. When receiving the lens state data request command, the lens barrel 20 detects the lens state and transmits the lens state data by communication LB. When the camera body 10 receives the lens state data, the camera body 10 executes processing B2.

  In the lens barrel 20, the process L1 in which the position detection units 25a and 25b acquire the lens position is executed in synchronization with the lens position acquisition signal. This lens position acquisition signal is generated at a predetermined timing, in the example of FIG. 18, when a half of the charge accumulation time at the center of the screen of the image sensor 2 has elapsed. The lens barrel 20 acquires position information of the focus adjustment lens by position detection units 25a and 25b that detect the position of the photographing lens at the timing of the state change of the lens position acquisition signal. These synchronous communications are executed in synchronization with the lens communication synchronization signal as a whole.

  As described above, in each embodiment of the present invention, the main body side display unit 6 that displays a plurality of selectable display patterns on the main body side display unit 6 and the touch panel 29 that detects a touch state on the display pattern are provided. Based on the display pattern and the detection result by the touch panel 29, the parameter change information is output to the camera side. In addition, when the function icon 6f and the selection pattern 6e are displayed on the display unit, when it is detected that the function icon 6f and the selection pattern 6e are associated by a touch operation, the touch panel 29 and the function icon 6f are associated with each other. ing. For this reason, the function of the touch panel provided in the lens barrel can be arbitrarily selected and customized by the user from among arbitrary functions.

  Further, in each embodiment of the present invention, when the function associated with the touch panel 29 is a function on the camera body side, the numerical value of the parameter is calculated according to the set function (S53 in FIG. 5), The calculated parameter values are transmitted to the camera body. For this reason, the camera body can be controlled from the lens barrel.

  In the embodiment of the present invention, the touch panel 29 is effectively used to increase the degree of freedom of lens operation and the user can select an operation method that the user is good at. In addition, a display that can intuitively determine the operation method is displayed. be able to. This display pattern can be selected from a plurality of patterns according to the user's preference. In the embodiment of the present invention, the display pattern is simply selected from the display patterns. However, the present invention is not limited to this, and the present invention can be applied to change the position and size of buttons and bars. May be customized by the user.

  Further, in the embodiment of the present invention, although the camera control by the user operation has to be performed in cooperation with the camera body 10 and the lens barrel 20, one display unit (the lens side display unit 28 or the body) It is possible to concentrate on the side display 6). Also, control that can be performed by the lens alone can be switched from the camera side while concentrating on photographing. In particular, the lens side operation unit such as the focus ring and zoom ring is in a position where it can be easily held and operated by hand and is often invisible when the camera is held, while the camera side display unit is In many cases, it is in a position that is easy to visually recognize at the time of shooting, and it has been difficult to perform a setting operation while viewing both screens. However, in the embodiment of the present invention, such a problem can be avoided. By designating a display pattern (for example, see FIG. 3B) from the camera body (or lens barrel) side, it is possible to correspond to an operation that was not assumed when the lens barrel (or camera body) was released. .

  In each embodiment of the present invention, the touch panel 29 and the control unit 21 are arranged in the lens barrel 20, and the main body side display unit 6 and the signal processing and control unit 1 are arranged in the camera body 10, and the processing is performed by both. I was going. Most of the above-described processing distribution may be executed by the control unit 21 of the lens barrel 20, and conversely, most of the processing may be executed by the signal processing and control unit 1 of the camera body 10. The distribution of processing may be determined as appropriate in consideration of the capabilities of both control units, signal processing capability, system characteristics, and the like.

  In each embodiment of the present invention, the lens side display unit 28 is provided in the lens barrel 20. By providing the display unit in the lens barrel 20, it becomes easy to confirm the setting contents on the lens barrel side, but it can be confirmed on the camera body 10 side, and may be omitted.

  In each embodiment of the present invention, the selection of the first pattern 6a to the fourth pattern 6d is performed on the camera body 10 side. Of course, the setting is performed on the lens barrel side while viewing the lens side display unit 28. Of course, it does not matter.

  In each embodiment of the present invention, a digital camera has been described as an apparatus for photographing. However, the camera may be a digital single lens reflex camera or a compact digital camera, such as a video camera or a movie camera. It may be a camera for moving images, or may be a camera built in a mobile phone, a smart phone, a personal digital assistant (PDA), a game machine, or the like.

  Further, regarding the operation flow in the claims, the specification, and the drawings, even if it is described using words expressing the order such as “first” and “next” for the sake of convenience, it is essential to carry out in this order. It does not mean that.

  The present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, you may delete some components of all the components shown by embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
