Description

Imaging device

The present invention relates to an imaging apparatus having a mount to which an accessory can be attached and detached, and in particular, when the accessory is a mount adapter, the imaging apparatus requests input of information regarding an interchangeable lens and controls the imaging apparatus based on the input information. About.

Generally, in an interchangeable lens camera, the interchangeable lens and the camera body have a mount that fits together. As shown in Japanese Patent Application Laid-Open No. 2004-12741, the interchangeable lens stores focal length information, pupil exit position information, information on changes in peripheral light quantity, unique information of the lens such as F number and aberration. The camera body communicates with the mounted interchangeable lens to acquire unique information regarding the interchangeable lens, and controls various operations and image processing of the interchangeable lens and the camera body based on the acquired unique information.

∙ The lens mount standard of the interchangeable lens may not match the body mount standard of the camera body. In this case, a mount adapter is used in order to allow the both to be mounted and used. The mount adapter is a ring-shaped member, and one end face is provided with a mount that conforms to the lens mount standard of the interchangeable lens, and the other end face is provided with a mount that conforms to the body mount standard of the camera body.

Generally, the mount adapter does not incorporate a mechanism for realizing communication between the interchangeable lens and the camera body. Since the electrical specifications for communication between the interchangeable lens and camera mount standards are different, making the mount adapter compatible with the electrical specifications complicates the configuration of the mount adapter and increases costs. To do. Therefore, in general, when using a mount adapter, the camera body cannot acquire information regarding the interchangeable lens via the mount adapter.

 One of the camera body operation controls is anti-vibration control that suppresses image blur caused by camera shake during imaging. In this anti-vibration control, camera shake is detected by a vibration gyro mechanism incorporated in the camera body, and the imaging optical axis is corrected by moving the imaging device in a phase opposite to the phase of vibration due to camera shake. Since the amount of camera shake correction depends on the focal length of the interchangeable lens, the image stabilization control is generally performed based on the focal length of the interchangeable lens.

However, as described above, when the interchangeable lens and the camera body are connected using the mount adapter, the camera body cannot acquire focal length information, which is one of the unique information of the interchangeable lens. For this reason, there is a possibility that the camera body cannot perform appropriate image stabilization control and cannot generate a suitable captured image.

Furthermore, since the camera body cannot acquire various kinds of unique information of the interchangeable lens, the camera body can appropriately control the operation according to the setting contents of the interchangeable lens being used at the time of imaging and the unique information on the captured image. Cannot add.

The present invention has been made in view of the above circumstances, and provides an imaging apparatus capable of performing operation control in accordance with the setting contents of an interchangeable lens when an interchangeable lens is used using a mount adapter. For the purpose.

According to an embodiment of the present invention, an imaging device having a mount that can be attached to and detached from an accessory, a communication unit that communicates with the accessory, a control unit that controls the imaging device, an input unit that receives user input, and a user A display unit that displays information related to input, and when the communication unit is able to communicate with the accessory and the accessory is identified as a mount adapter, the control unit is configured to store information regarding the interchangeable lens attached to the mount adapter. There is provided an imaging apparatus that displays a screen for requesting user input on a display unit and controls the imaging apparatus based on the user input when the user input is received.

According to the above configuration, information regarding the interchangeable lens attached to the mount adapter can be acquired by user input, and the operation control of the imaging apparatus can be accurately performed based on the acquired information.

If the communication unit cannot communicate with the accessory, the control unit may display a screen for requesting user input of information regarding the interchangeable lens on the display unit. As a result, even when a mount adapter that cannot communicate with the camera body is attached, information regarding the interchangeable lens attached to the mount adapter is acquired by user input, and the operation control of the imaging device is accurately performed based on the acquired information. Can do.

In addition, when the operation unit detects a user operation and the communication unit can communicate with the accessory and the accessory is identified as a mount adapter, the control unit includes a mount adapter. A screen requesting user input of information regarding the interchangeable lens mounted on the display unit may be displayed on the display unit, and when there is a user input, the imaging apparatus may be controlled based on the user input. Further, the operation means may be a button for releasing the lock between the accessory and the imaging device.

According to the above configuration, after turning on the power of the imaging apparatus, it is possible to execute user input of information regarding the interchangeable lens by pressing a button at an arbitrary timing. Reflecting can be performed.

In addition, the imaging apparatus includes an imaging element that converts a light image of a subject into an electrical signal, and an anti-vibration unit that performs anti-vibration control of the imaging element. The control unit may control the image stabilization unit based on information regarding the focal length of the interchangeable lens input by user input.

According to the above configuration, it is possible to accurately perform image stabilization control of the image sensor using the focal length of the interchangeable lens at the time of imaging, and to correct camera shake well.

Further, the display unit displays information regarding the interchangeable lens currently input by the user input and history information regarding the interchangeable lens previously input by the user input, and based on the user input, the currently input interchangeable lens The history information may be selected as the information regarding. Further, the control unit may change the selected history information based on the user input and set it as information regarding the currently input interchangeable lens.

According to the above configuration, for example, even when an interchangeable lens equipped with a zoom lens is attached to the mount adapter and the interchangeable lens is manually operated to frequently change the interchangeable lens setting such as the focal length, the history information is referred to. However, since information regarding the interchangeable lens can be input, user input can be performed more smoothly.

The control unit may add information about the interchangeable lens input by the user input to the image information generated by the imaging device, or add information about the accessory acquired by the communication unit to the image information generated by the imaging device. May be. As a result, even when imaging is performed using the mount adapter, information regarding the interchangeable lens used for imaging can be added to the image data in the same manner as when the interchangeable lens is directly attached to the imaging apparatus. It is done.

As described above, when an interchangeable lens is used using a mount adapter, an imaging device capable of performing operation control according to the setting content of the interchangeable lens is realized.

Hereinafter, a camera 100 according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is an external perspective view of the camera 100 according to the present embodiment. In the camera 100, a mount adapter 2 is attached to a camera body 1 as an imaging device, and an interchangeable lens 3 is attached to the mount adapter 2. As will be described later, the camera body 1 and the mount adapter 2 are connected via mounts of the same standard provided on both. Similarly, the mount adapter 2 and the interchangeable lens 3 are connected via mounts of the same standard provided on both.

FIG. 2 is a block diagram of the camera 100 according to the present embodiment. As shown in FIG. 2, the camera body 1 includes a CPU (Central Processing Unit) 10, a camera shake correction unit 11, an image sensor 12, an AFE (Analog Front Front End) 13, a TG (Timing Generator) 14, and a DSP (Digital Signal Processing Processor). ) 15, SDRAM (Synchronous Dynamic Random Access Memory) 16, EEPROM (Electrically Erasable Programmable Read-Only Memory) 17, SD card 18, display unit 19, input unit 20, push button switch 21, and body mount 22.

The CPU 10 is a control unit that integrally controls the operation of the camera body 1 based on various programs and setting data recorded in the EEPROM 17. The CPU 10 is also a communication unit that communicates with an accessory attached to the camera body 1. The setting data recorded in the EEPROM 17 includes not only focal length information and data set in advance, but also data that can be arbitrarily set by the user operating the input unit 20.

The image sensor 12 is a solid-state image sensor having photoelectric conversion elements arranged two-dimensionally on a substrate, and an optical image formed on the array surface (imaging surface) of the photoelectric conversion elements is converted into an electrical signal (analog image signal). Convert. In this embodiment, a CMOS (Complementary Metal Oxide Semiconductor) image sensor is used as the image sensor 12, but the configuration of the image sensor is not limited to this, and an image sensor having another configuration such as a CCD (Charge-Coupled Device) image sensor. May be used. The analog image signal generated by the image sensor 12 is converted into a digital image signal by the AFE 13.

The TG 14 generates various timing signals for driving the image sensor 12. The image sensor 12 performs vertical charge transfer and horizontal charge transfer according to the timing signal from the TG 14 and outputs an image signal to the AFE 13.

The DSP 15 is an image signal processing circuit, which performs various image processing on the digital image signal output from the AFE 13 according to the signal from the CPU 10 according to the processing conditions (image processing parameters) set by the user, and then the user. Is output as an image file in the file format (such as JPEG format).

The SDRAM 16 is a buffer memory that temporarily records image data processed by the DSP 15. The SD card 18 is a storage device that stores the image file output from the DSP 15. The SD card 18 is inserted into a memory card slot (not shown) of the camera body 1.

The display unit 19 is a display system that displays various information related to the setting contents and operation state of the camera body 1, a subject image or a reproduced image of image data, and the like.

The input unit 20 is an input device that accepts an input operation by a user. As shown in FIG. 3, the input unit 20 includes a power button 20 a for turning on and off the camera body 1, a cross key 20 b for changing and selecting setting contents of the camera body 1, and the camera body 1. An OK button 20c, a release button 20d, and an electronic dial 20i for enabling the change of the setting contents are provided. The function of each button of the input unit 20 will be described later.

As shown in FIG. 2, the interchangeable lens 3 includes a lens mount 40, a zoom sensor 41 that detects the position of the zoom lens 48, a lens position sensor 42 that detects the position of the focus lens 49, a lens CPU 43, a flash ROM 44, an aperture 45, A diaphragm motor 46 that adjusts the opening area of the diaphragm 45 and a motor driver 47 that drives and controls the diaphragm motor 46 are provided. The motor driver 47 is controlled by the lens CPU 43.

The lens mount 40 is a connection mechanism with the body mount of the camera body. In the present embodiment, there is no compatibility between the standard of the lens mount 40 and the standard of the body mount 22 of the camera body 1. Therefore, the interchangeable lens 3 cannot be directly attached to the camera body 1. Examples of such an interchangeable lens 3 include a case where an interchangeable lens manufactured by another company is used for the camera body, or a case where the camera body and the interchangeable lens are manufactured by the same company but the mounts are manufactured according to different standards. Is mentioned.

When the body mount 22 and the lens mount 40 have different standards, the mount adapter 2 is used when the camera body 1 and the interchangeable lens 3 are connected. The mount adapter 2 includes a camera side mount 30, a lens side mount 31, a flash ROM 32, a shutter 33, a shutter motor 34 that controls the operation of the shutter 33, and a motor driver 35 that controls the driving of the shutter motor 34.

The camera side mount 30 is composed of a lens mount of the same standard as the body mount 22 of the camera body 1. The lens side mount 31 is configured by a body mount of the same standard as the lens mount 40 of the interchangeable lens 3. Although not shown, the mechanical structure and dimensions of the fitting portion of the mount adapter 2 with respect to the camera body 1 and the interchangeable lens 3 are the so-called screw-in type, bayonet type, spigot type, etc. 3 is configured corresponding to each of the three mounting forms. In the present embodiment, the camera-side mount 30 of the mount adapter 2 is also electrically compatible with the body mount 22 of the camera body 1 so that it can communicate with the CPU 10 of the camera body 1. The lens side mount 31 of the mount adapter 2 is not electrically compatible with the lens mount 40 of the interchangeable lens 3 and does not have a configuration for transmitting a signal from the CPU 10 to the interchangeable lens 3. Therefore, the CPU 10 cannot acquire the unique information of the interchangeable lens 3 stored in the flash ROM 44 of the interchangeable lens 3 via the mount adapter 2 and cannot control the lens CPU 43.

The flash ROM 32 stores unique information related to the mount adapter 2. When the mount adapter 2 is attached to the camera body 1, the CPU 10 communicates with the flash ROM 32 and acquires unique information stored in the flash ROM 32. This unique information includes information for identifying the mount adapter 2.

When shooting with the camera 100, the camera body 1, the mount adapter 2, and the interchangeable lens 3 are connected as shown in FIG. When the user operates the power button 20a and fully presses the release button 20d with the power of the camera body 1 turned on, the image pickup device 12 causes the image pickup device 12 on the image pickup surface via the interchangeable lens 3 and the mount adapter 2. A subject image formed on the image is captured. The captured still image is converted from an analog signal to a digital signal by the AFE 13, subjected to various image processing by the DSP 15, and then displayed on the display unit 19. The captured still image data is converted into a file format set by the user and recorded on the SD card 18. Further, undeveloped image data (RAW image) generated by the image sensor 12 is temporarily recorded in the SDRAM 16. The RAW image recorded in the SDRAM 16 is used not only for preview display but also as a confirmation image when setting image processing parameters. The RAW image can also be recorded on the SD card 18.

The release button 20d turns on a metering switch and a release switch (not shown) according to the amount of pressing. For example, when the release button 20d is half-pressed, the photometry switch is turned on, and photometry is performed by exposure control. When the release button 20d is fully pressed, the release switch is turned on and imaging is performed. The image captured in response to the full press of the release button 20d may be a still image or a moving image.

The cross key 20b and the OK button 20c are operation buttons used for inputting various settings of the camera body 1. Using these operation buttons, for example, image processing parameters that determine conditions for image processing performed by the DSP 15 are set.

The cross key 20b has a left direction key 20e, an up direction key 20f, a right direction key 20g, and a down direction key 20h, and is arranged on the right side of the back side of the camera body 1 so as to surround the OK button 20c from four sides. By operating the cross key 20b in a state where various setting screens are displayed on the display unit 19, the setting contents of various processes in the camera body 1 are changed. When the OK button 20c is operated on the various setting screens, the changed setting content is confirmed. The changed contents are overwritten and saved in the EEPROM 17.

The electronic dial 20i is a disk-shaped input unit. The user rotates the electronic dial 20i clockwise or counterclockwise along the arrow direction shown in FIG. 3 to change various setting values such as a change in the depth of field at the time of imaging, or to input a focal length described later. The focal length on the screen can be changed.

The image stabilization unit 11 is an image stabilization unit that performs image stabilization control on the image sensor 12 based on the focal length of the interchangeable lens that is used when image stabilization occurs during image capture. In the present embodiment, the camera body 1 cannot acquire information related to the focal length of the interchangeable lens 3. Therefore, in this state, the image stabilization control of the image sensor 12 by the camera shake correction unit 11 cannot be performed accurately. Therefore, in the present embodiment, the image stabilization of the image sensor 12 by the camera shake correction unit 11 is performed using the focal length set by the user input.

Next, the setting of the focal length in this embodiment will be described in detail. For convenience of explanation, the processing step is abbreviated as “S” in the explanation and drawings in this specification.

FIG. 4 is a flowchart of the focal length input process according to the present embodiment. The focal length input process is performed prior to the normal shooting process (shooting mode) when the power of the camera body 1 is turned on. As shown in FIG. 4, when the user operates the power button 20a to turn on the power of the camera body 1, it is determined whether or not the interchangeable lens or the mount adapter 2 is attached to the camera body 1 (S201). Specifically, the CPU 10 tries to communicate with an accessory attached via the body mount 22. When the accessory is an interchangeable lens (not shown) or a mount adapter 2 having a mount of the same standard as the body mount 22, the CPU 10 acquires specific information from the flash ROM of the interchangeable lens or the flash ROM 32 of the mount adapter 2, and the accessory Identify. For convenience of explanation, it is assumed that the unique information stored in the flash ROM of the interchangeable lens having the same lens mount as the body mount 22 includes identification information and focal length information of the interchangeable lens. If it is determined that the interchangeable lens or the mount adapter 2 is attached to the camera body 1 (S201: YES), the process proceeds to S202. When the mount adapter does not include a flash ROM, when the identification information of the mount adapter is not included in the unique information acquired by the CPU 10, or when no accessory is attached to the body mount 22, the body mount 22 is used. If communication with the attached accessory is not possible, it is determined that the interchangeable lens or the mount adapter 2 is not attached to the camera body 1 (S201: NO), and the process proceeds to S203.

In S202, it is determined whether the focal length of the interchangeable lens has been detected based on the unique information acquired by the CPU 10 from the accessory. In the present embodiment, as described above, even if the mount adapter 2 and the interchangeable lens 3 are connected, the CPU 10 cannot acquire the focal length information of the interchangeable lens 3. Therefore, when the mount adapter 2 is attached to the camera body 1, it is determined that the focal length of the interchangeable lens 3 cannot be detected (S202: NO), and the process proceeds to S203. When the interchangeable lens is directly attached to the camera body 1, the CPU 10 can detect the focal length based on the unique information of the interchangeable lens (S 202: YES), and thus shifts to the normal shooting mode. When the camera 10 shifts to the normal photographing mode, the CPU 10 uses the detected focal length value or the focal length value determined by the focal length setting process described later to perform the image stabilization operation of the image sensor 12 by the camera shake correction unit 11. Can be accurately controlled. Also, the focal length value can be added as image information to the captured image data.

FIG. 5 is a flowchart of the focal length setting subroutine according to the present embodiment. When the process proceeds to S203, the focal length input screen is displayed on the display unit 19, and this subroutine is started. FIGS. 7A and 7B show focal length input screens in this subroutine. In S301, the focal length can be manually input. FIG. 7A shows a focal length input screen in S301. For convenience of explanation, in the present embodiment, it is assumed that the user has previously determined the focal length in this subroutine. A manual input value V is displayed near the center of the focal length input screen, and a history value H set in the past by the user is displayed as history information on the left side of the focal length input screen. If the user has not set a focal length in the past, a value set in advance is displayed as the history value H. The manual input value V displayed in S301 is a previously determined focal length value. When the focal length input screen is displayed on the display unit 19, the process proceeds to S302.

As shown in FIG. 7A, in this embodiment, the initial position of the cursor C is the most significant digit of the manual input value V. When the user operates the left key 20e or the right key 20g, the cursor C moves between the digits. The cursor C can be moved cyclically between the most significant digit and the least significant digit. When the user operates the up key 20f or the down key 20h, the value of the digit on which the cursor C is displayed increases or decreases. The user operates the cross key 20b to change the manual input value V to a desired value.

In S302, it is determined whether or not the manual input value V has been changed by the user operating the cross key 20b. If it is determined that the manual input value V has been changed by appropriately moving the cursor C by operating the cross key 20b (S302: YES), the changed manual input value V is displayed (S303), and the process proceeds to S304. move on.

In S304, it is determined whether or not the focal length input is completed by the user operating the OK button 20c. When the user operates the OK button 20c (S304: YES), the process proceeds to S305, where the manual input value V is determined as the focal length setting value, and this subroutine is terminated. When the user does not operate the OK button 20c (S304: NO), the process proceeds to S302.

Here, the function of the electronic dial 20i will be described. When the user rotates the electronic dial 20i, the cursor C moves from the manual input value V to any one of the history values H displayed on the focus input screen. FIG. 7B shows a state (history selection state) in which the cursor C is moved to the history value H using the electronic dial 20i. In the present embodiment, when the electronic dial 20i is rotated to the right, the cursor C sequentially moves the history value H from top to bottom, and when the electronic dial 20i is rotated to the left, the cursor C causes the history value H to move from the bottom. Move sequentially up. As the manual input value V, the history value H selected by the cursor C is displayed. When the electronic dial 20 i is used, the cursor C is positioned between the uppermost value (“15.0” in the figure) of the history value H and the manually input value V, or at the lowermost portion of the history value H. It can move cyclically between the value (“135.0” in the figure) and the manual input value V. In the present embodiment, when the user operates the right direction key 20g in the history selection state, the cursor C moves to the manual input value V and is manually input with the history value H selected by the cursor C immediately before the movement. The value V is updated. Then, the user can change the manual input value V by operating the cross key 20b as described above.

If the user has not operated the cross key 20b in S302 (S302: NO), the process proceeds to S306. In S306, it is determined whether or not the history value H has been selected by moving the cursor C by the user operating the electronic dial 20i. When the user operates the electronic dial 20i (S306: YES), the cursor C moves to the history value H and enters a history selection state (S307), and the process proceeds to S308. When the user has not operated the cross key 20b and the electronic dial 20i (S306: NO), the process proceeds to S304.

In S308, it is determined whether or not the manual input value V is updated with the history value H when the user operates the right key 20g in the history selection state. When the user operates the right key 20g in the history selection state (S308: YES), the cursor C moves to the manual input value V, and the history value H displayed in the manual input value V is changed. (S309), and the process proceeds to S304. When the user does not operate the right key 20g in the history selection state (S308: NO), the process proceeds to S310.

In S310, it is determined whether or not the selection by the cursor C has returned from the history value H to the manual input value V again by continuing to operate the electronic dial 20i in the history selection state. Therefore, when the user returns the cursor C to the manual input value V without operating the right direction key 20g (S310: YES), the manual input value V is displayed as the manual input value V immediately before the history selection state. The displayed value is displayed again, and the manual input value V can be changed (S311), and the process proceeds to S304. If the user has not operated the right key 20g and the electronic dial 20i in the history selection state (S310: NO), the process returns to S308. When the history selection state is canceled and the cursor C returns from the history value H to the manual input value V, it is arbitrarily set in advance to which digit of the manual input value V the cursor C is displayed. Just keep it.

In the present embodiment, since the previously determined focal length value is displayed as the manual input value V in S301, if the user wants to use the same focal length value as the previous time, the user simply operates the OK button 20c. Good. That is, when the user presses the OK button 20c in the state where the previously determined focal length is displayed as the manual input value V, the process proceeds in the order of S302, S306, S304, and S305, and the previously determined value is determined again as the focal length. This subroutine ends. As shown in FIG. 4, when this subroutine is completed, the process proceeds from S203 to the shooting mode.

In the above description, since the focal length input process is executed only when the power of the camera body 1 is turned on, the interchangeable lens is zoomed when the interchangeable lens is replaced while the power of the camera body 1 is turned on. If the focal length of the zoom lens is changed by manual operation when the lens is a lens, the CPU 10 cannot acquire information regarding the focal length after lens replacement or after manual lens operation. For this reason, precise operation control based on appropriate focal length information cannot be performed on the camera body 1 side. In view of this, the present embodiment is further configured such that the setting content of the focal length can be changed at an arbitrary timing after the camera body 1 is turned on. Specifically, as will be described later, an interrupt routine is started by the push button switch 21.

FIG. 6 is a flowchart of an interrupt routine for making this change in the present embodiment. As shown in FIGS. 1 and 2, a push button switch 21 is provided on the front surface of the camera body 1. When the user fits the accessory on the body mount 22 and performs a turning operation, the accessory is locked to the camera body 1 by a component such as a latch (not shown). When the user presses the push button switch 21, the lock by a component such as a latch is released, and the accessory can be detached from the camera body 1 by rotating the accessory while pressing the push button switch 21. As shown in FIG. 2, the CPU 10 is electrically connected to the push button switch 21 and can detect the operation of the push button switch 21 by the user.

If the push button switch 21 is pressed at an arbitrary timing after the camera body 1 is turned on, the process proceeds to S401. In S <b> 401, the CPU 10 tries to acquire the unique information of the accessory attached via the body mount 22, and determines whether or not the mount adapter is attached to the camera body 1. If it is determined that the mount adapter is attached (S401: YES), the process proceeds to S402, and the subroutine shown in FIG. 5 is executed. Since the processing contents of the subroutine are as described above, description thereof is omitted. The accessory attached to the camera body 1 is not a mount adapter, for example, when the accessory is removed and no accessory is attached to the camera body 1 or when an accessory that does not have the mount adapter identification information is attached to the camera body 1. Is determined (S401: NO), this interrupt routine is terminated and the process shifts to the photographing mode.

As described above, in the present embodiment, the user can change the set focal length only by pressing the push button switch 21 after the focal length is determined by the routine shown in FIGS. Can do. Even when the zoom of the interchangeable lens 3 is changed manually, the focal length can be changed in the same manner. By providing the push button switch 21 with a trigger function for changing the focal length, the focal length can be easily changed at any timing without affecting the functions already assigned to the various buttons of the input unit 20. can do. Thus, accurate image stabilization control of the image sensor 12 and creation of captured image information can be performed using an appropriate focal length value.

This completes the description of the exemplary embodiment of the present invention. Embodiments of the present invention are not limited to those described above, and various modifications are possible within the scope of the technical idea of the present invention. For example, in the above description, the case where the user is requested to input the focal length information has been described. However, the user may be requested to input various lens information necessary for operation control of the camera body 1. This makes it possible to perform control processing suitable for the lens characteristics of the interchangeable lens attached to the mount adapter on the camera body 1 side. Further, various buttons used by the user in the above routine can be changed as appropriate. The camera body 1 may be newly provided with buttons and assigned with the various functions described above. Furthermore, each value displayed on the focal length input screen can be displayed on the display unit 19 with an arbitrary configuration.
