Description

  The present invention relates to an imaging apparatus having an electronic viewfinder function for sequentially displaying captured images and a control method thereof.

  Along with the optical viewfinder, many image pickup apparatuses having an electronic viewfinder (hereinafter also referred to as EVF or live view) function that captures image information of a shooting range using an image pickup device and displays the image information on a liquid crystal monitor or the like have been proposed. The characteristics of EVF are that it is not easily affected by the darkness of the outside world, that is, it is suitable for use when the brightness is reduced, the depth of field is easy to check, and display by processing such as image enlargement is possible. Easy things are mentioned.

By the way, during the display on the live view screen by the EVF function, the movable mirror moves to the mirror-up position and the shutter is open, so that the light incident on the lens cannot be guided to the focus state detection sensor. Therefore, autofocus (hereinafter abbreviated as AF) processing using the sensor cannot be performed. Therefore, if there is an AF start instruction during display by the EVF function, AF processing using the focus state detection sensor can be performed once image display by the EVF function is stopped. A proposal has been made to restart the display operation by the EVF function at the time of focusing or at the timing desired by the user (see Patent Document 1).
On the other hand, an imaging device capable of smoothly transitioning to a screen other than the live view (for example, a menu display screen or a captured image playback screen) while the movable mirror remains in the mirror-up state during image display by the EVF function Exists.

JP 2009-42366 A

  During live view shooting, an AF start operation may be used as a trigger in order to return to a live view screen from a screen other than the live view described above. At this time, if an AF method that does not require a mirror-down operation, for example, a contrast method AF (hereinafter referred to as contrast AF), a transition to the live view screen can be made smoothly. This is because the AF control is performed while the live view screen is displayed after the transition to the live view screen, so that the mirror down operation is not required.

On the other hand, in the case of an AF method that requires a mirror down operation, for example, a phase difference detection AF (hereinafter referred to as phase difference detection AF), the mirror down operation is performed before the transition to the live view screen. After that, AF control is performed, and after the AF control is finished, a transition is made to a live view screen. For this reason, when the user performs an AF start operation with the intention of transition to the live view screen, the time required for transition to the display screen may become longer depending on the AF method. For example, a mirror operation occurs every time the user performs an AF start operation while the live view screen is displayed, which hinders smooth screen transition.
Therefore, an object of the present invention is to smoothly transition from a display screen other than the live view to the live view screen regardless of the difference in the AF method.

  In order to solve the above-described problem, an apparatus according to the present invention includes a first display for live view display of an image captured by an image sensor and a second display for displaying at least one of image playback display and menu display. A movable mirror movable to a first position on the subject optical axis and a second position retracted from the subject optical axis, and the movable mirror includes the first mirror and the movable mirror. Selection means capable of selecting at least one of a first type of automatic focus adjustment performed at the position and a second type of automatic focus adjustment performed when the movable mirror is at the second position; , An operation means capable of instructing the start of automatic focus adjustment and an instruction to transition from the second display to the first display by the same operation, and the automatic focus adjustment of the first method are selected. In the state Even when the operation is performed by the operation means when the moving mirror is in the second position and the second display is being performed, the second display can be started without operating the movable mirror. Control means for controlling to make a transition to the first display.

  According to the present invention, the transition from the second display to the first display can be smoothly performed even when the automatic focus adjustment method is a method involving movement of a movable mirror.

This is a movable mirror that can move between the second position and the second position for performing imaging. That is, both mirrors are in the mirror-down state at the first position, and the mirror is in the mirror-up state at the second position, and two states can be selectively taken. In the mirror-down state, light is guided to the optical viewfinder 104 and the focus state detection unit 42, and observation of the subject via the optical viewfinder 104 and detection by the focus state detection unit 42 are possible. In the mirror-up state, the mirror 130 and the sub mirror (not shown) are retracted from the subject optical axis, and the light from the photographing lens 310 directly reaches the image sensor 14. Therefore, in this state, a live view function for continuously displaying captured images on the image display unit 28 based on the output of the image sensor 14 or shooting is possible.

  The power switch 72 is a switch for instructing the power supply to the apparatus main body 100 to be turned on or off, and can set the mode switching when the power is turned off. By operating the power switch 72, it is possible to set the power on / off of the lens unit 300, the external strobe, the recording medium 200, 210, etc. connected to the apparatus main body 100.

It also has a function as a memory.

The operation of the first embodiment of the present invention will be described below with reference to the flowchart of FIG. This process is realized according to a program executed by the system control unit 50.
In S1001, screen display processing by the live view function is performed, and the camera is in the live view state. In next step S1002, the photographer operates the menu button of the operation unit 70, the system control unit 50 receives this operation instruction, and the process proceeds to step S1003. Here, the image display unit 28 transitions to the display state of the menu screen. The display on the menu screen can be changed while the mirror 130 is retracted from the subject optical axis during the display of the live view screen.

When the shutter switch 62 is operated as an AF start unit in S1004, that is, when SW1 is turned on, the process proceeds to S1005. Here, the system control unit 50 determines whether or not the AF method (control method) at the time of the AF start operation is a method involving a mirror down operation related to the mirror 130. As a result, if it is determined that the AF method is not a method involving a mirror down operation, the process proceeds to S1006. If it is determined that the AF method is a method involving a mirror down operation, the process proceeds to S1007.
In step S1006, the image display unit 28 transitions to a live view state in accordance with a command from the system control unit 50. Thereafter, AF control is performed in S1008. As an AF method that does not involve a mirror down operation, for example, a contrast method can be cited.

On the other hand, if the AF method is a method involving a mirror down operation, the image display unit 28 transitions to the live view state in accordance with a command from the system control unit 50 in S1007, but AF control is not performed. As an AF method involving a mirror down operation, for example, a phase difference detection method can be cited.
After S1007 and S1008, the above series of processing ends. In this example, the menu screen is described as an example of the second display screen other than the live view, but the display screen is not limited. That is, any screen may be used as long as the display screen can be changed in a state where the mirror 130 is maintained in the mirror-up state by the live view operation command.

  According to the first embodiment, the transition to the live view state by the operation of the switch SW1 can be smoothly executed even when the AF method is a method involving mirror down. That is, when it is determined that the AF method is a method involving the movement of the movable mirror, it is possible to transition to the live view screen without operating the movable mirror. Also, if the user operates the switch SW1 in a state where a screen other than the live view screen is displayed and instructs the start of AF accompanied by mirror down, the user cannot confirm the shooting target until AF control ends. Therefore, according to the present embodiment, when the user gives an AF start instruction, it is possible to prompt the user to check the shooting target on the live view screen.

[Second Embodiment]
Next, a second embodiment of the present invention will be described. The configuration of the imaging apparatus according to the second embodiment is the same as the configuration shown in FIG.
The operation of the imaging apparatus according to the second embodiment will be described using the flowchart of FIG. Note that the processing in S1101 to 1106 and S1108 is the same as the processing in S1001 to 1006 and S1008 in FIG. 2, so description thereof will be omitted and the following description will focus on differences.

If it is determined in S1105 that the AF method is a method involving a mirror down operation, the process proceeds to S1107, where the system control unit 50 measures the operation time during which the switch SW1 is pressed, and the length of the operation time is determined in advance. It is determined whether or not it is equal to or greater than the reference value. As a result, if it is determined that the operation time length of SW1 is less than the reference value, the process proceeds to S1109. If it is determined that the operation time length is greater than or equal to the reference value, the process proceeds to S1110.
If the operation time of the switch SW1 is short, it is determined that the user does not intend to perform the AF control with the mirror down operation, and the image display unit 28 transitions to the live view state in S1109, and the process ends.

  On the other hand, if the operation time of the switch SW1 is longer than the predetermined time, it is determined that the user has an intention to perform the AF control with the mirror down operation, and the mirror down operation is performed in S1110. In step S1111, AF control is performed. In step S1112, the system control unit 50 determines whether the focusing operation is successful. If it is not yet in focus, the process returns to S1111 and AF control is continued. If the focusing is successful, the process proceeds to S1113, and the image display unit 28 transitions to the live view state, and then the process ends.

In the second embodiment, in addition to the effect of the first embodiment, whether to switch from the menu screen to the live view state by the operation of the switch SW1, or to perform the AF control with the mirror down operation, Since it can be changed by the user's intention, operability is improved. In the case of a method involving a mirror down operation, since the mirror down operation and AF control are performed when the SW1 operation time is long, the user can reliably instruct the apparatus to start AF. Further, when the operation time of SW1 is short, the mirror down operation and the AF control are not performed, so that it is possible to prevent the mirror from operating every time the operation is performed.
The present invention can also be realized by executing the following processing. That is, software (program) that realizes the functions of the above-described embodiments is supplied to a system or apparatus via a network or various storage media, and a computer (or CPU, MPU, or the like) of the system or apparatus reads the program. It is a process to be executed.
