Description

  The present invention relates to a photographing apparatus, a photographing control method, and a program.

  2. Description of the Related Art Conventionally, there is known a moving image shooting apparatus that can manually set a shutter speed according to a user's purpose and application. In moving image shooting, since it is necessary to open and close the shutter during shooting of one frame, the exposure period must be set shorter than the frame interval. That is, the shutter speed needs to be higher than the reciprocal of the frame rate. However, when the shutter speed and the frame rate are set individually, it may be possible to set the shutter speed to be lower than the reciprocal of the frame rate. There was a problem that would happen. Therefore, as disclosed in Patent Document 1, a technique for controlling the setting of the frame rate according to the set shutter speed is disclosed.

Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS.
This embodiment exemplifies a case where the present invention is applied to a digital camera as a photographing apparatus, and FIG. 1 is a block diagram showing basic components of the digital camera.
This digital camera has various functions and can shoot moving images and still images. That is, an imaging function that can capture a subject with high definition, a shooting function that records and saves a captured image as a moving image or a still image, and a recorded image that has been recorded (saved image) is arbitrarily read and played back In addition to basic functions such as an image playback function, in this embodiment, in particular, a function for shooting at a high frame rate of 240 fps (frame per second) is provided in moving image shooting.

  The control unit 1 operates by supplying power from the power source unit (secondary battery) 2 and controls the overall operation of the digital camera according to various programs stored in the storage unit 3. The unit 1 is provided with a CPU (Central Processing Unit) and a memory (not shown).

  The storage unit 3 includes, for example, a ROM, a flash memory, and the like, and includes a program for realizing the present embodiment, various applications, and a later-described FIG. 5 according to an operation procedure illustrated in FIGS. The program memory 3A in which the program diagram shown in FIG. 4 is stored, the work memory 3B in which flags are temporarily stored, the image memory 3C in which moving images, still images, and the like are stored. The storage unit 3 may include a removable portable memory (recording medium) such as an SD card or an IC card, and is connected to a network via a communication function (not shown). The state may include a storage area on a predetermined server device side.

  The operation unit 4 includes various push button type keys. For example, a mode change button for switching between a shooting mode and a playback mode for playing back a captured image (stored image), a recording button for instructing start and end of moving image shooting, and a shutter button for instructing execution of still image shooting In addition, there are provided setting buttons for setting shooting conditions, such as a frame rate setting button 4A for changing the setting of a frame rate (included in moving image quality) for moving image shooting and a shutter speed setting button 4B for changing the setting of shutter speed. Yes. The control unit 1 executes, for example, a mode change process or a shooting condition (frame rate, shutter speed, etc.) setting process as a process according to the input operation signal from the operation unit 4. In this embodiment, the frame rate setting change and the shutter speed setting change are selected from a setting menu for changing various shooting condition settings, and the frame rate setting button 4A and the shutter speed setting button 4B are: It is realized as an operation to select frame rate setting change and shutter speed setting change from this setting menu, but each can be an independent button, each can be selected from a different menu, and the implementation method is arbitrary It is. Also, by selecting the moving image quality as the moving image shooting condition, the frame rate setting and the image size setting can be changed together, but the frame rate setting may be changed independently. .

  The display unit 5 is a display screen composed of high-definition liquid crystal or organic EL (Electro-Luminescence), and can be a monitor screen (live view screen) that displays captured images (live view images) in real time or has been photographed It may be a playback screen for playing back images.

  The imaging unit 6 constitutes a camera unit capable of photographing a subject with high definition, and has zoom adjustment, focus adjustment, automatic exposure adjustment (AE), automatic focus adjustment (AF) functions, and the like. In response to the control signal, zoom adjustment, focus adjustment, automatic exposure adjustment (AE), and shooting start / end are controlled by driving a zoom lens, a focus lens, and a diaphragm / shutter (not shown). When a subject image from an optical lens system such as a zoom lens and a focus lens is formed on the image sensor in the imaging unit 6, an image signal (analog value signal) read out by photoelectric conversion is digital value data. And sequentially output as a frame image. The display unit 6 converts the sequentially output frame image into a screen size and displays it in real time as a live view image. Then, in accordance with a moving image shooting start instruction operation by the recording button by the operation unit 4 or a still image shooting execution instruction operation by the shutter button, the frame image output at the operation timing is acquired, and processing such as white balance and sharpness is performed. After the compression encoding process is performed, the data is recorded and saved in the image memory 3C of the storage unit 3 (for example, an SD card). In the present embodiment, moving image shooting at a high frame rate is possible, but since it can be realized by a well-known technique, detailed description is omitted here.

  FIG. 2 is a schematic diagram illustrating an operation screen that enables a shutter speed setting change by a user operation in moving image shooting, and an input operation from the shutter speed setting button 4B changes the setting of the shutter speed for moving image shooting. It is an operation screen that is displayed when selected. On this operation screen, the currently set shutter speed and the range of settable shutter speeds are displayed. The shutter speed that can be set in the present embodiment can be set by numerical values that are normally used, such as 1/60 sec, 1/125 sec, and 1/250 sec. The currently set shutter speed is displayed as a numerical value (1/250), and the range of shutter speeds that can be set is displayed with 12 indices arranged at the peripheral edge of the right circle. Each of the twelve indices indicates the shutter speed, and the shutter speed is higher in the clockwise direction. And the range which can be set is shown by changing the color of these indicators. Here, “Black” indicates the currently set shutter speed (1/250 sec), “White” indicates a high-speed shutter speed within a settable range other than the currently set shutter speed, and “Gray” The shutter speed is lower than 1/250 sec, which cannot be set by.

  3 and 4 are schematic diagrams illustrating a live view screen in moving image shooting. In FIG. 3, 240 fps is set as the frame rate currently set at the upper right of the screen, and the shutter speed currently set at the lower left is shown. 1/250 sec is displayed. FIG. 4 shows a case where the frame rate setting is changed to 480 fps by the user operation from the state of FIG. 3. In this case, the shutter speed setting is automatically changed to 1/500 sec, which is faster than the inverse of 480. Is displayed.

FIG. 5 is a schematic diagram illustrating a program diagram used for performing appropriate exposure adjustment in moving image shooting, and shows an example in which the frame rate is set to 240 fps. The program diagram is prepared for each frame rate and stored in the program memory 3A. The oblique axis indicates the ISO100 converted light value (LV value), the horizontal axis indicates the shutter speed (sec), and the vertical axis indicates the aperture (F value) and the sensitivity (ISO).
Since the frame rate is set to 240 fps, the shutter speed is set or automatically adjusted at 1/250 sec or less, which is faster than the inverse of 240. The aperture is set or automatically adjusted between the minimum aperture F8 and the maximum aperture F2.8. The sensitivity is indicated by a gain coefficient with ISO 100 as a reference (+0). The upper limit ISO 3200 is +32, and is automatically adjusted within this range.
The “L” -shaped line located on the upper side indicates how the shutter speed and sensitivity are changed according to the light value in the shutter speed priority mode (S mode) that prioritizes the set shutter speed. In the aperture priority mode (A mode) that prioritizes the set aperture, how the shutter speed and aperture change in accordance with the light value This indicates whether or not
In the S mode, for example, when the user sets the shutter speed to 1/250 sec, the sensitivity is automatically set according to the change of the light value in a state where the shutter speed is fixed to 1/250 sec. Is set. However, since the lower limit of the sensitivity that can be set is +0, in the range where the light value exceeds 11, the shutter speed is changed with the sensitivity fixed at +0.
That is, as indicated by an arrow “variable in S mode”, the position of the vertical portion of the “L” -shaped line changes to the left and right according to the setting of the shutter speed by the user.
In the A mode, for example, when the user sets the aperture to F5.0, the shutter speed is set according to the change of the light value in the state where the aperture is fixed at F5.0 in the range where the light value is 13 or more. Set automatically. However, since the lower limit of the shutter speed that can be set according to the frame rate of 240 fps is 1/250 sec, the sensitivity is changed with the shutter speed and the aperture fixed when the light value is less than 13. .
That is, as indicated by an arrow “variable in A mode”, the position of the horizontal portion of the “one” shape changes up and down according to the diaphragm setting by the user.
When the frame rate is set to 240 fps, the range of the light value up to 6 that the shutter speed is the lower limit (1/250 sec), the aperture is open (F2.8), and the sensitivity is the upper limit (ISO3200) is appropriate. Exposure adjustment is possible. In the present embodiment, even if a proper exposure cannot be obtained because the value is lower than the light value, the moving image shooting is not prohibited and the shooting is executed.
In S mode, the range of shutter speed that can be manually set by the user according to the frame rate setting (the range indicated by the arrow “variable in S mode”) changes automatically, and in A mode, it is automatically set according to the frame rate setting. The range of shutter speeds set in (the range indicated by the arrow “variable in S mode”) changes.
In addition to the above example, for example, when the frame rate is 120 fps, the shutter speed range is 1/125 or less, and when the frame rate is 1000 fps, the shutter speed speed range is 1/2000 or less. Become.

  Next, the operation concept of the digital camera in the present embodiment will be described with reference to the flowcharts shown in FIGS. Each function described in these flowcharts is stored in the form of a readable program code, and an operation according to the program code is sequentially executed under the control of the control unit 1. In addition, the operation according to the above-described program code transmitted via a transmission medium such as a network can be similarly executed under the control of the sequential control unit 1. FIG. 6 is a flowchart showing an overview of the moving image shooting control process, which is a characteristic part of the present embodiment, of the entire operation of the digital camera. When the flowchart of FIG. Returning to the main flowchart (not shown). In FIG. 6, it is assumed that the S mode that prioritizes the setting of the shutter speed is set.

  FIG. 7 is a flowchart that is started when the user gives an instruction to change the setting of the shooting conditions, and is executed under the control of the control unit 1.

  First, in a state where a live view image at the time of moving image shooting is being displayed, whether or not an operation for instructing a change in setting of shooting conditions has been performed as a user operation (step A1 in FIG. 6), and a start instruction for moving image shooting It is determined whether or not it has been performed (step A2). If neither (NO in step A1, NO in step A2), processing corresponding to other operations such as a zoom operation is performed (step A3). Return to A1 and repeat the process.

  If it is determined that an operation for instructing to change the shooting condition setting has been performed (YES in step A1), a shooting condition setting change process is performed (step A4).

  The photographing condition setting change process will be described with reference to the flowchart shown in FIG. If it is determined that an operation for instructing to change the shooting condition setting has been performed (YES in step A1), it is determined whether or not the frame rate setting has been changed (whether or not the frame rate setting change button 4A has been operated) (step B1). Then, it is determined whether or not the shutter speed setting is changed (whether the shutter speed setting change button 4A is operated) (step B2). If neither is determined (NO in step B1, NO in step B2). Then, processing according to other operations such as changing the aperture setting is performed (step B3), the process exits the flowchart of FIG. 7, returns to the flowchart of FIG. 6, and repeats the process of step A1.

  If it is determined that the frame rate setting is changed (YES in step B1), an operation screen is displayed that allows the frame rate setting to be changed by a user operation (not shown) (step B4). On this operation screen, by selecting the moving image quality, frame rates such as 120 fps, 240 fps, and 480 fps can be selected together with the image size.

  When it is determined on the operation screen displayed in step B4 that an operation for changing the frame rate from the current setting has been performed (YES in step B5), the setting is changed to a frame rate corresponding to the operation (step B6). A range of shutter speeds that can be set is specified in accordance with the changed frame rate (step B7). For example, when the frame rate setting is changed to 480 fps, the shutter speed range that can be set is specified to be 1/500 sec or less, which is higher than the inverse of 480. On the other hand, when it is determined that the operation for changing the frame rate from the current setting has not been performed (NO in step B5), the process exits the flowchart of FIG. 7 and returns to the flowchart of FIG. 6 to repeat the process of step A1. .

  Next, the currently set shutter speed is acquired (step B8), and it is determined whether or not the acquired shutter speed is outside the range of the shutter speed specified in step B7 (step B9). If it is determined that the acquired shutter speed is outside the specified shutter speed range (YES in step B9), the shutter speed setting is automatically changed to be within the specified range (step B10). 7) Exit the flowchart of FIG. 7, return to the flowchart of FIG. 6, and repeat the process of step A1. For example, as shown in FIG. 3, when the frame rate is changed to 480 fps as shown in FIG. 4 from the state where the frame rate is 240 fps and the shutter speed is set to 1/250 sec, the shutter speed is changed. Is automatically changed to 1/500 sec so as to fall within the specified range. On the other hand, if it is determined that the acquired shutter speed is not outside the specified shutter speed range (NO in step B9), the process exits the flowchart of FIG. 7 and returns to the flowchart of FIG. 6 to repeat the process of step A1. .

  If it is determined that the setting is not a change in the frame rate but a change in the shutter speed (NO in step B1, YES in step B2), the currently set frame rate is acquired (step B11). A shutter speed that can be set according to the frame rate is specified (step B12), and a shutter speed setting change operation screen showing the specified range is displayed as shown in FIG. Here, the settable shutter speed is limited. FIG. 2 shows that the acquired frame rate is 240 fps, and a shutter speed of 1/250 sec or less can be set.

  If it is determined that the operation for changing the shutter speed from the current setting has been performed (YES in step B14), the setting is changed to the shutter speed corresponding to the operation (step B15), and the flowchart of FIG. Returning to the flowchart, the process of step A1 is repeated. On the other hand, if it is determined that the operation for changing the shutter speed from the current setting has not been performed (NO in step B14), the process exits the flowchart of FIG. 7 and returns to the flowchart of FIG. 6 to repeat the process of step A1. .

  Returning to the description of FIG. 6, when it is determined that the operation for instructing to change the setting of the shooting condition is performed as a user operation in Step A <b> 1 (NO in Step A <b> 1), and it is determined that the operation for instructing the start of moving image shooting is performed ( In step A2, YES, a program diagram corresponding to the set frame rate as shown in FIG. 5 is acquired from the program memory 3A.

  Next, it is determined whether or not the light value received by the imaging device of the imaging unit 6 is a value that allows appropriate exposure adjustment in the acquired program diagram (step A6). In the case of FIG. 5, since the frame rate is set to 240 fps, it is determined whether or not the lower limit of the shutter speed is 1/250 sec.

  If it is determined that appropriate exposure adjustment is possible with the acquired program diagram (YES in step A6), other imaging parameters (aperture, sensitivity) are adjusted based on the acquired program diagram (step A7). ), Moving image shooting is started (step A9). On the other hand, when it is determined from the acquired program diagram that appropriate exposure adjustment is not possible (NO in step A6), as described above, the shutter speed is set to the lower limit (1/250 sec) and the aperture is opened (F2.8). ), The sensitivity is set to the upper limit (+32) (step A8), and moving image shooting is started (step A9).

  When the moving image shooting is started, the moving image shooting is continued until it is determined that the moving image shooting end instruction operation is performed (NO in step A10), and it is determined that the moving image shooting end instruction operation is performed (YES in step A10). Then, the shooting moving image is filed (step A11), and the moving image shooting control process is terminated. The operation and process for forcibly ending the movie shooting control process are omitted, but the movie shooting control process can be forcibly terminated as appropriate by changing to the playback mode or turning off the power. It has become.

  As described above, in the first embodiment, the control unit 1 is set even when the shutter speed is arbitrarily set by the user operation by the shutter speed setting change button 4B based on the set frame rate. You can shoot movies with priority on the frame rate. In particular, it is effective for high frame rate moving image shooting in which the importance of frame rate is high.

  Further, since the control unit 1 controls the range of shutter speeds that can be set by the shutter speed setting change button 4B based on the set frame rate, moving image shooting can be performed with priority on the set frame rate.

  Further, since the control unit 1 limits the shutter speed range that can be set by the shutter speed setting change button 4B to the shutter speed range that can ensure moving image shooting at the set frame rate, the shutter speed can be changed by a user operation. It is possible to reliably ensure the set frame rate.

  Further, since the control unit 1 can set the frame rate and the shutter speed by the shutter speed setting change button 4B in any order, the user is restricted in the timing for changing the shutter speed setting. The shutter speed setting can be changed without receiving.

  Further, when the shutter speed is set by the shutter speed setting change button 4B in the state where the frame rate is set, the control unit 1 sets the range of shutter speeds that can be set at the time of the setting so that the user can recognize. Therefore, the user can recognize a settable shutter speed range.

  Further, since the shutter speed range that can be set by the shutter speed setting change button 4B controlled by the control unit 1 is displayed on the display unit 5, the user can visually recognize the settable shutter speed range. .

  In addition, since an arbitrary frame rate can be set by a user operation using the frame rate setting change button 4A, it is possible to set a frame rate according to the user's purpose and preference.

  In addition, when the frame rate is set while the shutter speed is set by the shutter speed setting change button 4B, the control unit 1 changes the set shutter speed based on the set frame rate. Since the control is performed regardless of the user operation, the shutter speed is automatically changed regardless of the user operation so that the frame rate set later is prioritized regardless of the shutter speed previously set. Can do.

  In addition, the control unit 1 performs control to change the shutter speed set by the shutter speed setting change button 4B to the shutter speed at which moving image shooting at the set frame rate can be ensured regardless of the user operation. Even if the set shutter speed does not ensure movie shooting at the frame rate set later, the shutter speed is changed to a shutter speed that can ensure movie shooting at the automatically set frame rate, regardless of user operation. can do.

  Further, since the control unit 1 performs appropriate exposure adjustment by controlling the setting of other shooting parameters based on the shutter speed set by its own control, even when the shutter speed is automatically controlled. You can shoot movies with appropriate exposure.

  Further, since the control unit 1 performs moving image shooting even when appropriate exposure adjustment cannot be performed, it is possible to reliably perform moving image shooting without missing a valuable shooting opportunity.

  In the above-described embodiment, the frame rate and shutter speed set before starting moving image shooting cannot be changed during moving image shooting. However, the frame rate or shutter speed can be changed by user operation during moving image shooting. The setting may be changed.

  In the embodiment described above, the S mode is set. However, when the A mode is set and the aperture setting is changed, the following processing is performed. When the program diagram of FIG. 5 is used, the position of the horizontal portion of the “-” shape is changed up and down to the changed aperture according to the aperture setting change, and based on the program diagram, Exposure adjustment is performed based on the shutter speed and sensitivity with a lower limit of 1/250 sec.

  Further, in each of the above-described embodiments, the case where the present invention is applied to a digital camera has been shown. However, the present invention is not limited to this, and a personal computer with a camera function, a PDA (personal portable information communication device), a tablet terminal device, a smartphone, etc. It may be a mobile phone, electronic game, music player, or the like.

  Further, the “apparatus” and “unit” shown in each of the above-described embodiments may be separated into a plurality of cases by function, and are not limited to a single case. In addition, each step described in the above-described flowchart is not limited to time-series processing, and a plurality of steps may be processed in parallel or separately.

The embodiment of the present invention has been described above. However, the present invention is not limited to this, and includes the invention described in the claims and the equivalent scope thereof.
