Description

  The present invention relates to an imaging apparatus having a shooting mode for automatically starting a live view and having a function for ending a live view and a moving image recording function for protecting an imaging device, and a control method thereof.

  In recent years, an interchangeable-lens digital camera that captures a still image with a live view shooting function added is known. In a single-lens reflex camera, for example, as disclosed in Patent Document 1, if live view is performed at the time of lens replacement, an image sensor is exposed, so it is proposed to end live view for the purpose of protecting this. ing.

  Even if the power supply is cut off during the live view in the Olympus E-300, E-420 (registered trademark), etc., the camera automatically enters the live view state when the power is turned on next time. There is something to return. In addition, in this camera, in order to end the live view when the lens is replaced, when the user operates the lens mount lock release button, live view end control is performed.

JP 2006-313250 A

By the way, when the live view is terminated at the time of lens replacement as described above, the following problem occurs in a system in which communication between the lens and the camera body is performed by an electronic contact via the lens mount.
For example, if an accessory that cannot communicate with the lens is attached to the lens mount, this state cannot be distinguished from the state without the lens. For example, when an old lens without an electronic contact is attached with a lens mount adapter, a live view is displayed. Can not start.

  In addition, in an SLR camera, an optical viewfinder is usually used, and in order to start a live view, the photographer needs to be familiar with the operation for that purpose. Conventionally, there is a camera that starts live view in response to a button operation. However, with a camera that enables video recording by extending live view, video recording cannot be performed unless live view start operation is performed. In other words, in order to record a moving image, it is complicated because an operation for starting a moving image must be performed after an operation for starting a live view is performed.

  In view of this, there has been proposed a camera that automatically displays a live view when an image of a movie camera is displayed in pictograms in the shooting mode of the camera and the shooting mode is set to the moving image mode. However, when exchanging lenses during live view, if live view is terminated to protect the image sensor, inconvenience arises. That is, with this type of camera, it is assumed that the user does not need to operate by starting the live view automatically. Therefore, even if the user wants to restart the live view after completing the lens exchange, it is difficult to know how to start the live view.

The conventional apparatus does not propose any means for solving the processing in the case where the live view is intentionally restarted without a lens.
In addition, in an apparatus that terminates live view triggered by the lens mount lock release button being pressed during lens replacement, live view is possible when the user presses the live view start button without a lens. If you turn off the power while the live view is started, the live view will start automatically the next time you turn on the power. However, if the lens is not attached when the power is turned on, the live view is not started and the normal optical viewfinder is merely used. Therefore, in a camera having a moving image mode, it is desirable to prompt the user to start the live view. In addition, when the live view is terminated in order to protect the image sensor at the time of lens replacement, it is preferable to present an operation for starting the live view to the user after the lens replacement.

  An object of the present invention is to provide an easy-to-understand operation when a live view is to be performed by mounting an optical component other than a lens on a main body in an interchangeable lens imaging device.

  In order to solve the above-described problems, the present invention is an interchangeable lens imaging device having a live view function for displaying an image on a display device, and an operation member for manually starting the live view and a mode are selected. A mode selection member for performing the control, and a live view is automatically started according to the mode selected by the mode selection member, and the live view is automatically ended according to detection of the state of the main body. The control means to perform is provided. When the live view is terminated in response to detection of a state where the lens is not attached to the main body, the display means that the live view can be started by the operation member without starting the live view. To display.

  According to the present invention, when a user attaches or detaches a lens during live view, if the live view is automatically terminated to protect the image sensor, a method for starting the live view is presented to the user in an easy-to-understand manner. can do.

The lens 101 is an interchangeable lens that can be attached to and detached from the main body of the camera 100. A release button 102 provided on the upper surface of the main body can be turned on in a first switch (denoted as SW1) 213 and a second switch (denoted as SW2) 214 described later by being pushed in two stages by a push button. It is an operation member. The electronic dial 103 located near the release button 102 is an operation member that can detect the rotation direction and the rotation amount. The ISO button 104 is an operation member used when changing the ISO setting value.

  The mode dial 105 is an operation member for switching a desired mode, for example, a shooting mode such as Tv priority, Av priority, fully automatic, and moving image mode by rotation. By switching the mode dial 105 to the moving image mode position, the camera 100 automatically starts live view. The power lever 106 is a power operation member for turning on / off the power to the camera 100. When the photographer turns on the power when the mode dial 105 is set to the moving image mode position, the camera 100 automatically starts live view.

  The FPSEL button 107 located at the upper right on the back of the main body is an operation member used when selecting a distance measuring point. The AEL button 108 on the left side is an operation member used when performing AE lock. The DISP button 109 located on the upper left side of the back of the main body is an operation member used when switching the contents to be displayed on the rear display 119 described later. The MENU button 110 on the left side is an operation member used when displaying a menu screen by GUI (Graphical User Interface) display on the rear display 119.

A lens attaching / detaching button 111 provided on the front surface of the main body is an operation member for releasing the lock pin of the lens mount when the lens is exchanged. In this embodiment, it is detected that the user has pressed the lens attaching / detaching button 111, and this is not immediately determined as attaching / detaching the lens.
The AvComp button 112 provided on the back of the main body is an operation member for changing the operation target by pressing the electronic dial 103 together when the electronic dial 103 is turned. The ED button 113 is an operation member for the user to instruct the start and end of moving image recording in the moving image mode. The ED button 113 also serves as an operation member that can start the live view when the live view ends when the user attaches or detaches the lens in the moving image mode. When the lens is attached or detached, a message such as “Starting live view when the ED button is pressed” is displayed on the rear display 119.

  The SET button 114 is an operation member used when operating a GUI such as a menu together with the cross key 116. The card cover 115 is a cover that protects a slot for storing a recording medium such as a flash memory card. The trash can button 117 is an operation member used when deleting the data of the photographed image. The PLAY button 118 is an operation member used for displaying a photographed image. A display panel made of TFT, organic EL, or the like is used for the rear display 119.

FIG. 2 is a diagram illustrating a circuit configuration example of the interchangeable lens camera 100. A portion 205 (see LENS) surrounded by a rectangular frame at the upper left indicates a component on the interchangeable lens side, and the other portion indicates a component on the camera side.
The interchangeable lens is provided with an aperture driving device 200 (see EMD), an encoder 201 (see ENCF), a motor 202 (see LMTR), and a lens control microprocessor (hereinafter referred to as LPU) 203. The encoder 201 reads the lens driving position by the motor 202 and sends the detection result to the LPU 203. A motor 202 is a drive source for performing focus driving of the lens, and is controlled by a signal from the LPU 203.

  The control microprocessor (hereinafter referred to as MPU) 207 of the camera 100 includes a nonvolatile memory such as a ROM, a flash memory, and an EEPROM, and a volatile memory such as a RAM. As the MPU 207, a one-chip microcomputer in which various I / O circuits are incorporated can be used. Therefore, details of the interface between the MPU 207 and other circuits are omitted in the figure. For example, the connection between the AF sensor 217 (refer to AF-SNS) used for focus adjustment and the MPU 207 is connected by a solid line in the figure, but both are actually connected by a serial communication interface.

The AF sensor 217 is disposed on a surface where the light flux from the lens optical system is divided and optically equivalent to the imaging surface, and operates according to a control command from the MPU 207 by serial communication. The AF sensor 217 transmits focus detection data for use in phase difference AF to the MPU 207 by serial communication.
An interchangeable lens driver (hereinafter referred to as LCM) 204 has a function of supplying power to a connection terminal with the interchangeable lens in accordance with a control instruction from the MPU 207 and relaying serial communication. The driver 204 informs the MPU 207 whether or not the lens is mounted based on the energization state of the electronic contacts of the lens mount.
A contact 223 indicated by MNT in the drawing is an electronic contact, and electrically connects the LPU 203 and the LCM 204.

A display driver (hereinafter referred to as DDR) 215 for driving the liquid crystal display device is connected to the MPU 207 for displaying an image during live view or moving image shooting, and displaying a message or the like on the liquid crystal display unit 216 when an error occurs. It is a circuit part. The DDR 215 operates according to a control instruction from the MPU 207. The DDR 215 includes a switch input port, and can notify the MPU 207 of the switch detection state.
The first switch SW1 indicated by reference numeral 213 and the second switch SW2 indicated by reference numeral 214 are the switches already described in the release button 102 of FIG. These are connected to the interrupt ports of the MPU 207, and their ON / OFF state is detected.

  A motor 212 (see MTR1) used for the operation of the camera 100 is driven and controlled by the MPU 207 via a driver, and a photographing operation is performed by the normal rotation of the motor 212, and a strobe pop-up operation is performed by the reverse rotation. A port denoted by reference numeral 208 (see SMG1) and a port denoted by reference numeral 209 (see SMG2) are signal output ports for controlling the shutter travel of the camera 100. These are connected to respective electromagnets 210 (see MG1) and 211 (see MG2) through amplifiers.

  The ED switch 221 corresponds to the ED button 113 in FIG. 1 and is a switch for instructing start and end of live view and start and end of moving image recording. A switch 219 is a power switch for turning on and off the power of the camera 100. The CVR switch 220 is a switch for detecting an open / closed state of a lid provided in a slot for attaching a flash memory card or the like to the camera 100.

The switches 222 collectively shown as SWS in the figure are various switches provided in the camera 100, and include, for example, switches corresponding to the cross key 116 in FIG. 1 (not shown individually). Operation instructions by the above switches are input to the MPU 207.
A plurality of switches 218 (see MODE) attached to the DDR 215 are mode selection switches for switching the shooting mode of the camera 100, and are switches corresponding to the mode dial 105 in FIG. Where the position of the mode dial 105 is, a gray pattern is formed by four contacts, and the mode position is identified by the combination of the on / off state of each switch.
An imaging element (hereinafter referred to as CMOS) 206 images a subject through a lens, processes a signal related to a captured image, and sends the processed signal to the MPU 207. The CMOS 206 is provided with a temperature sensor 224 (see TMPM) for measuring the ambient temperature, and temperature detection information is notified to the MPU 207.

  Hereinafter, operations related to the present invention in the camera 100 configured as described above will be described. First, when the mode dial 105 is set to the moving image mode position, live view starts, and an image formed on the CMOS 206 is displayed on the rear display 119. Thereafter, the user presses the ED button 113 once to start moving image recording, and the display content on the rear display 119 changes from the display during live view to the display during moving image recording. Then, when the user presses the ED button 113 during moving image recording, the moving image recording ends, and the state returns to the live view state.

  When the lens 101 is removed from the camera body during live view, the live view is terminated. FIG. 7 shows an example of a message displayed on the rear display 119 at this time, and the user is notified about confirmation of lens mounting and start of the live view function by pressing the ED button 113. The same applies when the user turns off the power while the mode dial 105 is in the moving image mode position and turns the power on again with the lens removed.

  In the state where the message display of FIG. 7 is performed, only the operation of starting the live view with the ED button 113, the operation of turning off the power with the power lever 106, and the operation of switching to another mode with the mode dial 105 are possible. The device does not accept the operation instruction. The user can open the card cover 115 and replace the flash memory card, or open the battery cover (not shown) and replace the battery. However, when the cover is opened, the power is shut off. This is the same as the operation of turning off the power with the lever 106. When power is turned on with the lid closed, the message in FIG. 7 is displayed. A similar notification may be given by voice together with the message.

  When the ED button 113 is pressed while the message of FIG. 7 is displayed in the moving image mode with the lens removed from the main body of the camera 100, the live view starts. When an optical system component that cannot perform lens communication via the electronic contact 223 is attached to the mount of the camera 100, the live view is started by this operation. For example, there is a case where the user wants to record a moving image or the like using an optical system component that cannot perform lens communication, and lens communication is possible in that a desired operation starts when the user presses the ED button 113 during live view. This is the same as when using a lens.

  When the ED button 113 is pressed during moving image recording, the moving image recording ends and the state returns to the live view state. At this time, an event of transitioning to the live view occurs as a state change, but it is determined that the transition to the live view is made upon return from moving image recording. By doing so, consideration is given so that the process of displaying FIG. 7 is not started instead of starting the live view when the lens is not attached to the main body of the camera. The live view is also stopped when the live view cannot be continued because the internal temperature of the camera rises and exceeds the reference temperature due to continuing the live view for a long time. Also at this time, in order to resume the live view, the user needs to press the ED button. However, since the live view cannot be resumed until the internal temperature of the camera has dropped below the reference temperature, a message such as “Live view has been interrupted due to a temperature rise.” Is displayed so that the user can stop the operation. It is preferable to make it.

  Details of the program for realizing the above operations will be described with reference to the flowcharts of FIGS. Note that these processes are realized by processing various hardware connected to the I / O port of the MPU 207 in accordance with a program stored in the ROM. In order to understand the processing shown in each flowchart, an outline of the configuration of the program stored in the ROM will be described. The program is described so as not to directly execute a process for starting or ending the live view based on a determination result such as a button operation instruction or the presence / absence of a lens. When starting and ending the live view, there are some programs that generate the request, and the start and end of the live view is actually controlled by executing the program that accepts the request. As a result, even if the live view start condition occurs repeatedly while the live view is already being performed, the redundant start operation is not performed. In the following description, the “live view start request” at step 400 in FIG. 4 and the “live view end request” at step 600 in FIG. 6 indicate the start of processing for accepting such a request. On the other hand, FIG. 3 and FIG. 5 show processing that starts with the operation of the camera 100 as a trigger.

First, the flow of processing will be described with reference to FIG. A “live view start operation” denoted by reference numeral 300 indicates the beginning of processing when the camera 100 receives an instruction for a live view start operation. Here, the start operation of the live view may be applicable in the following situation.
-When the user sets the mode dial 105 to the position of the moving image mode.
When the user presses the ED button 113.
When the user moves the power lever 106 to the power ON position from the power-off state.
・ When starting from auto power off.
This process is called when the above operations are performed.

  In step 301, the MPU 207 determines whether or not the mode dial 105 is in the moving image mode position. As a result, if the selected mode is not the moving image mode, the process proceeds to “Return” in Step 309. If the selected mode is the moving image mode, the process proceeds to step 302. Here, the MPU 207 determines whether or not the GUI is a normal display. Here, the normal display means a state in which a special display such as a screen for reporting the occurrence of an error is not performed on the rear display 119. For example, the rear display 119 displays the setting value of the camera 100 or displays nothing at all. If it is determined that the current display state is not normal display, the process proceeds to step 309. If it is determined that the current display state is normal display, the process proceeds to the next step 303.

  Based on the detection information of the temperature sensor 224, the MPU 207 determines whether or not the temperature of the CMOS 206 is a temperature at which live view can be performed. The CMOS 206 continuously performs an image pickup operation for live view. For this reason, if power is continuously supplied, the temperature rises. Since this temperature depends on the environment in which the camera 100 is placed, it is determined based on the detection result of the temperature sensor 224. As a result, if it is determined that the temperature is low and is not more than the prohibition temperature of live view, the process proceeds to step 305. If it is determined that the temperature is higher than the prohibited temperature, the process proceeds to step 304. Here, a warning is displayed when the temperature reaches the prohibited temperature. That is, processing for displaying on the rear display 119 that the live view has been terminated due to the temperature rise as a message to the user is performed. Then, the process proceeds to Step 308.

Since the processing in steps 303 and 304 is performed from the processing in steps 300 to 307, the live view start operation is manually performed even if the user presses the ED button 113 until the temperature falls below the prohibited temperature. become unable.
In step 305, the MPU 207 determines whether live view has already been performed. As a result, when it is determined that the live view is being performed, the process proceeds to step 309. Otherwise, the process proceeds to next step 306. Here, the MPU 207 determines whether or not the power is on. As a result, if the power is off, the process proceeds to step 308; otherwise, the process proceeds to step 307, and the MPU 207 issues a live view start request. That is, a control instruction is issued for a process that receives a live view start request described later.

In step 308, the MPU 207 issues a live view end request. That is, a control instruction is issued for a process that receives a live view end request to be described later.
When the return step 309 is reached from steps 302, 305, 307, and 308, the processing in this figure ends.

Next, processing when a live view start request is generated will be described with reference to FIG.
A “live view start request” indicated by reference numeral 400 is the head of processing when the program receives a live view start request.
In step 401, the MPU 207 determines whether or not a moving image is currently being recorded. As a result, if it is determined that the moving image recording is in progress, the process proceeds to “moving image recording end” in step 405 to end the moving image recording and return to the live view state. If it is determined that moving image recording is not in progress, the process proceeds to step 402 “moving image mode AND lens mounted?” (AND represents a logical product operation that satisfies all of a plurality of conditions). Here, the MPU 207 determines whether or not the current mode is the moving image mode and a lens is attached to the main body. The determination of the moving image mode has already been performed in step 301 in FIG. 3, but the mode selection information is information that depends on the position of the operation member, and is therefore treated redundantly. If no lens is attached to the main body of the camera 100 or if the current mode is not the moving image mode, the process proceeds to step 407 “moving image mode AND no lens AND no lens warning?”. If both conditions in step 402 are satisfied, the process proceeds to “start live view operation” in step 403. The live view operation is started, and in this state, the light flux from the lens reaches the CMOS 206 by the mirror up operation and the shutter opening.

In the next step 404, processing for returning a notification that the live view is in progress to the program that issued the live view start request is performed. Thereafter, the process proceeds to step 412.
On the other hand, when the moving image recording end process is performed in step 405, the process proceeds to step 406. After the process associated with the state transition from the moving image recording to the live view is performed, the process proceeds to step 404.

  When the process reaches step 407 from step 402, the MPU 207 determines whether or not the current mode is the moving image mode, no lens is mounted on the main body, and no lens warning is being displayed. . If these three conditions are satisfied, the process proceeds to step 403, and the live view start process is performed even when there is no lens. Further, if even one of the three conditions is not satisfied, “Power OFF OR Error state OR Lens is in the middle of power OFF?” In step 408 (OR represents an OR operation in which any one of a plurality of conditions is satisfied. ) Here, the MPU 207 determines whether or not the power is off, whether or not it is in an error state, and whether or not it is in the process of shifting to the power off state even when the lens is attached. If any one of the conditions is met, the process proceeds to step 412. If neither condition is met, the process proceeds to “live view impossible lens no warning” in step 409. Since it is not recognized that the lens is attached to the main body of the camera 100, a message indicating that live view cannot be performed is displayed on the rear display 119 as a warning.

  Then, the process proceeds to step 410, and a warning display indicating that the lens is not attached to the main body is performed. Since the switches that can be operated thereafter differ depending on the operating state, a state transition process is performed. For example, even if the user continues to press the first switch 213 in this state, the metering process is stopped, and operations other than the power lever, ED button, mode dial, card cover, and battery cover are not accepted. Processing is performed.

In the next step 411, a process for returning a notification that the normal shooting has been performed as a result is performed to the program that has issued the live view start request, and the process proceeds to step 412. When the return step 412 is reached, the processing in this figure ends.
Next, a process for determining whether or not to start the live view operation when the user performs the live view start operation by pressing the ED button 113 will be described with reference to FIG.

  “ED button ON” indicated by reference numeral 500 is the head of processing when the ED button 113 is pressed. In step 501, the MPU 207 determines whether live view is currently being performed. If the ED button 113 is pressed during live view, the process proceeds to “start moving image recording” in step 502. Then, after the moving image recording is started, the process proceeds to step 503.

  If it is determined in step 501 that it is not in the live view state, the process proceeds to “moving image recording state?” In step 504. Here, the MPU 207 determines whether or not a moving image is currently being recorded. If the ED button 113 is pressed during moving image recording, the process proceeds to step 505, and moving image recording ends according to an instruction from the MPU 207. In order to finish the moving image recording and return to the live view, in step 506, a live view start request is issued. On the other hand, if it is determined in step 504 that the moving image is not being recorded, the process proceeds to “normal shooting state?” In step 507. Here, the MPU 207 determines whether or not it is in a normal shooting state at the present time. As a result, if the camera is in the normal shooting state, the process proceeds to step 506. If the camera is not in the normal shooting state, the process proceeds to “Warning display state?” In step 508. Here, the MPU 207 determines whether or not a warning is currently displayed on the rear display 119. If it is determined that the state is the warning display state, the process proceeds to step 506 in order to start the live view by operating the ED button 113, but if not, the process proceeds to step 503. When the return step 503 is reached from steps 502, 506, and 508, the processing in this figure ends.

Next, processing when a live view end request is generated will be described with reference to FIG.
A “live view end request” indicated by reference numeral 600 is the head of processing when the program receives a live view end request. In step 601, the MPU 207 determines live view. As a result, if the live view is not currently being performed, the process proceeds to “normal shooting notification” in step 607. If the live view is currently being performed, the process proceeds to “moving image mode?” In step 602. The MPU 207 determines whether or not the mode dial 105 is in the moving image mode position. As a result, if the video mode is not set, the process proceeds to “live view operation end” in step 606.

  On the other hand, in the case of the moving image mode in step 602, the process proceeds to step 603, “Power OFF OR Error State OR Power OFF with lens? Here, the MPU 207 determines whether the power is off, whether it is in an error state, and whether the power is being turned off when the lens is attached. If either condition is met, the process proceeds to step 606. If each condition is not satisfied, the process proceeds to “live view impossible lens no warning” in step 604. Here, since the lens is not attached to the main body, a notification process for issuing a warning that live view cannot be performed is performed. In the next step 605, a state transition process is performed during the warning of no lens, and the process proceeds to step 606.

  When step 606 is reached from step 602, 603, or 605, mechanical components are controlled in accordance with an instruction from the MPU 207 in order to end the live view operation. Then, the process proceeds to step 607, where the live view operation is completed, the mirror down is performed, and the normal shooting state is obtained, and a reply to the live view end request is notified. In the next return step 608, the processing in this figure is completed.

  As described above, in a single-lens reflex camera having a moving image mode, a user can simply use a live view by simply using a mode selection member such as a mode dial to match the position to the position of the moving image mode. In this case, it is preferable to end the live view in order to protect the image sensor when the lens is attached or detached. According to the present embodiment, when a lens adapter or the like is used, it is possible to easily display to the user how the live view can be resumed by manual operation.
