JP 2006-148273 A Japanese Patent No. 3944926

  Image effect processing that adds a visual effect to a partial region of an image (Patent Document 1) with an imaging device (Patent Document 1) that can independently set an aspect ratio of a still image and an aspect ratio of a moving image. Is considered based on the position (area) designated by the user. Here, if the position (area) for performing image effect processing is specified in common for still images and moving images, the still images and the moving images will differ if the aspect ratios set for the still images and moving images are different. There is a possibility that the impression of the result of processing is different. That is, an image having an image processing result different from the user's intention when the position for performing the image effect processing is designated is recorded. This is because the position specified for the image effect processing differs between the still image and the moving image because the aspect ratios of the still image and the moving image are different.

  The present invention has been made in view of the above-described problems, and performs shooting that performs image effect processing based on a position designated by a user in different types of recording operations (for example, still images and moving images) as intended by the user. An object is to provide an imaging apparatus that can be executed.

Designation means for allowing the user to designate a range in the image displayed on the display unit by the image display;
Image processing means for performing image processing on the image photographed by the first or second recording operation using a range designated by the designation means;
When shooting in the second recording operation is performed while performing the image processing, shooting is performed by changing the aspect ratio in the second recording operation to the first aspect ratio, and otherwise, the shooting is performed. Execution means for executing photographing by the second recording operation at a second aspect ratio.

  According to the present invention, it is possible to perform photographing that performs image effect processing based on a position designated by the user as intended by the user in different types of recording operations (for example, still images and moving images).

  Hereinafter, an example of a preferred embodiment of the present invention will be described with reference to the accompanying drawings. In the embodiments described below, a case where the apparatus and method according to the present invention are applied to an imaging apparatus that is a digital camera capable of shooting by a plurality of types of recording operations such as still images and moving images will be described as an example.

《Digital camera configuration》
FIG. 1A shows an external view of a digital camera as an imaging apparatus according to the present embodiment. The display unit 28 includes a liquid crystal panel (LCD), for example, and is used to display images and various information. The shutter button 61 is an operation button for giving a shooting instruction. The moving image button 63 is an operation button for instructing start / end of moving image shooting. The mode switch 60 is an operation unit for switching various modes. The connector 112 is a connector for connecting the connection cable 111 and the digital camera 100. The operation unit 70 includes operation members such as various switches, buttons, and a touch panel that receive various operations from the user. The controller wheel 73 is a rotatable operation member included in the operation unit 70. The power switch 72 switches on / off the power supply in the digital camera 100. The recording medium 200 is a recording medium such as a memory card or a hard disk. The recording medium slot 201 is a slot for storing the recording medium 200. The recording medium 200 stored in the recording medium slot 201 can communicate with the digital camera 100. A lid 202 is a lid for opening and closing the recording medium slot 201.

  FIG. 1B is a block diagram illustrating a configuration example of the digital camera 100 according to the present embodiment. In FIG. 1B, the photographing lens 103 is a lens group including a zoom lens and a focus lens. The shutter 101 is a mechanical shutter having an aperture function. The imaging unit 22 has an imaging device composed of a CCD, a CMOS device, or the like that converts an optical image into an electrical signal. The A / D converter 23 converts the analog signal output from the imaging unit 22 into a digital signal. The lens barrier 102 covers the imaging system including the imaging lens 103 of the digital camera 100, thereby preventing the imaging system including the imaging lens 103, the shutter 101, and the imaging unit 22 from becoming dirty or damaged.

  The image processing unit 24 performs a resizing process and color conversion process such as predetermined pixel interpolation and reduction on the data from the A / D converter 23 or the data from the memory control unit 15. The image processing unit 24 performs predetermined calculation processing using the captured image data, and the system control unit 50 performs exposure control and distance measurement control based on the obtained calculation result. Thereby, AF (autofocus) processing, AE (automatic exposure) processing, and EF (flash pre-emission) processing of the TTL (through-the-lens) method are performed. The image processing unit 24 further performs predetermined calculation processing using the captured image data, and also performs TTL AWB (auto white balance) processing based on the obtained calculation result.

  Output data from the A / D converter 23 is directly written into the memory 32 via the image processing unit 24 and the memory control unit 15 or via the memory control unit 15. The memory 32 stores image data obtained by the imaging unit 22 and converted into digital data by the A / D converter 23 and image data to be displayed on the display unit 28. The memory 32 has a storage capacity sufficient to store a predetermined number of still images, a moving image and sound for a predetermined time.

  The memory 32 also serves as an image display memory (video memory). The D / A converter 13 converts the image display data stored in the memory 32 into an analog signal and supplies the analog signal to the display unit 28. Thus, the display image data written in the memory 32 is displayed on the display unit 28 via the D / A converter 13. The display unit 28 performs display according to the analog signal from the D / A converter 13 on a display such as an LCD. A digital signal once A / D converted by the A / D converter 23 and stored in the memory 32 is converted into an analog signal by the D / A converter 13 and sequentially transferred to the display unit 28 for display. Can be done. In this way, the display unit 28 provides a function as an electronic viewfinder by performing real-time moving image display.

  The nonvolatile memory 56 is an electrically erasable / recordable memory, and for example, an EEPROM or the like is used. The nonvolatile memory 56 stores constants, programs, and the like for operating the system control unit 50. Here, the program includes a program for executing various flowcharts described later in the present embodiment.

  The system control unit 50 controls the entire digital camera 100. The system control unit 50 includes a computer, and the computer executes the program recorded in the nonvolatile memory 56 described above, thereby realizing each process of the present embodiment described later. The system memory 52 is composed of, for example, a RAM, and is used to develop constants and variables for operation of the system control unit 50, a program read from the nonvolatile memory 56, and the like. The system control unit 50 also performs display control by controlling the memory 32, the D / A converter 13, the display unit 28, and the like. The system timer 53 measures the time used for various controls and the time of a built-in clock.

  The mode switch 60, the first shutter switch 61, the second shutter switch 62, the moving image button 63, and the operation unit 70 are user interfaces for inputting various operation instructions to the system control unit 50.

  The mode switch 60 switches the operation mode of the system control unit 50 to any one of a still image recording mode, a moving image recording mode, a reproduction mode, and the like. Modes included in the still image recording mode include an auto shooting mode, an auto scene discrimination mode, a manual mode, various scene modes for shooting settings for each shooting scene, a program AE mode, a custom mode, and the like. The mode changeover switch 60 can directly switch to one of these modes included in the still image recording mode. Alternatively, after switching to the still image recording mode once with the mode switch 60, the mode may be switched to any one of these modes included in the still image recording mode using another operation member. Similarly, the moving image recording mode may include a plurality of modes.

  The shutter button 61 includes a first shutter switch 62a and a second shutter switch 62b. The first shutter switch 62a is turned on when a shutter button 61 provided in the digital camera 100 is being operated, so-called half-press (shooting preparation instruction), and generates a first shutter switch signal SW1. In response to the first shutter switch signal SW1, operations such as AF (autofocus) processing, AE (automatic exposure) processing, AWB (auto white balance) processing, and EF (flash pre-emission) processing are started. The second shutter switch 62b is turned on when the operation of the shutter button 61 is completed, so-called full depression (shooting instruction), and generates a second shutter switch signal SW2. In response to the second shutter switch signal SW2, the system control unit 50 starts a series of shooting processing operations from reading a signal from the imaging unit 22 to writing image data on the recording medium 200.

  The moving image button 63 gives instructions for starting and ending moving image shooting. At the start of the moving image, the system control unit 50 performs operations such as AF (autofocus) processing, AE (automatic exposure) processing, and AWB (auto white balance) processing. Then, the system control unit 50 reads out the signal from the imaging unit 22, and writes the moving image data (moving image recording) by writing to the recording medium 200 at the same time as writing to the memory 32 via the memory control unit 15. To do. When the moving image ends, the remaining moving image data stored in the memory 32 is written to the recording medium 200, and the moving image recording ends.

  Each operation member of the operation unit 70 is appropriately assigned a function by selecting and operating various function icons displayed on the display unit 28, and functions as various function buttons. Examples of the function buttons include an end button, a return button, an image advance button, a jump button, a narrowing button, and an attribute change button. For example, when a menu button is pressed, various setting menu screens are displayed on the display unit 28. The user can make various settings intuitively using the menu screen displayed on the display unit 28, and the four-way button and the SET button.

  The controller wheel 73 is a rotatable operation member included in the operation unit 70, and is used when a selection item is instructed together with a direction button. When the controller wheel 73 is rotated, an electrical pulse signal is generated according to the operation amount. From this pulse signal, it is possible to determine the angle at which the controller wheel 73 is rotated, how many rotations, and the like. The system control unit 50 controls each unit of the digital camera 100 based on the pulse signal. The controller wheel 73 may be any operation member that can detect a rotation operation. For example, it may be a dial operation member that generates a pulse signal by rotating the controller wheel 73 itself according to the rotation operation of the user. Further, an operation member made of a touch sensor may detect the rotation operation of the user's finger on the controller wheel 73 without rotating the controller wheel 73 itself (so-called touch wheel).

  The power control unit 80 includes a battery detection circuit, a DC-DC converter, a switch circuit that switches a block to be energized, and the like, and detects whether or not a battery is installed, the type of battery, and the remaining battery level. Further, the power control unit 80 controls the DC-DC converter based on the detection result and an instruction from the system control unit 50, and supplies a necessary voltage to each unit including the recording medium 200 for a necessary period.

  The power supply unit 30 includes a primary battery such as an alkaline battery or a lithium battery, a secondary battery such as a NiCd battery, a NiMH battery, or a Li battery, an AC adapter, or the like. The recording medium I / F 18 is an interface with the recording medium 200 such as a memory card or a hard disk. The recording medium 200 is a recording medium such as a memory card for recording a captured image, and includes a semiconductor memory, a magnetic disk, or the like.

<< Overall Operation of Digital Camera 100 >>
FIG. 2 is a flowchart for explaining the overall operation of the digital camera 100 of the present embodiment. Each process in the flowchart is realized by the system control unit 50 expanding and executing a program stored in the nonvolatile memory 56 or the like in the system memory 52.

  When the power switch 72 is operated to turn on the power, the system control unit 50 initializes flags, control variables, and the like in S201. Subsequently, in S <b> 202, the system control unit 50 starts management processing related to the file recorded on the recording medium 200. In S203 and after, it is determined to which mode the mode changeover switch 60 has been switched, and an operation corresponding to that is executed. If it is determined in S203 that the mode switch 60 has been switched to the still image recording mode process, the process proceeds to S204, and the system control unit 50 executes the still image recording mode process. The still image recording mode process will be described later with reference to FIGS. 3A and 3B. If it is determined in S205 that the mode switch 60 has been switched to the moving image recording mode, the process proceeds to SS206, and the system control unit 50 executes the moving image recording mode process. The moving image recording mode process will be described later with reference to FIG. If it is determined in S207 that the mode switch 60 has been switched to the playback mode, the process proceeds to S208, and the system control unit 50 executes the playback mode process.

  If another mode has been set, the process proceeds to S209, and the system control unit 50 executes a process according to the selected mode. Other modes include, for example, a transmission mode process for transmitting a file stored in the recording medium 200, a reception mode process for receiving a file from an external device and storing it in the recording medium 200, and the like. After executing the process corresponding to the mode set by the mode switch 60 among S204, S206, S208, and S209, the process proceeds to S210. In S210, the system control unit 50 determines the set position of the power switch 72. If the power switch 72 is set to power-on, the process returns to S203 and the above-described process is repeated. On the other hand, if the power switch 72 is set to power off, the process proceeds from S210 to S211 and the system control unit 50 performs an end process. The termination process includes, for example, the following process. That is, the display on the display unit 28 is changed to the end state, and the lens barrier 102 is closed to protect the imaging unit. In addition, parameters, setting values, and setting modes including flags and control variables are recorded in the nonvolatile memory 56, and the power to parts where power supply is unnecessary is cut off. When the end process of S211 is completed, this process ends, and the digital camera 100 shifts to a power-off state.

《Still image recording mode processing》
3A and 3B are flowcharts showing still image recording mode processing, and are details of the processing in S204 of FIG. 2 described above. Each process in the still image recording mode process is realized by the system control unit 50 expanding and executing a program stored in the nonvolatile memory 56 or the like in the system memory 52. Note that the still image recording mode processing shown in FIGS. 3A and 3B is performed by interrupt processing when the mode switch 60 is switched to another mode or when the power switch 72 is set to OFF. It shall end.

  When starting the still image recording mode, the system control unit 50 determines the shooting mode in S301. The shooting mode is determined by acquiring the shooting mode at the end of the previous still image recording mode from the nonvolatile memory 56 and storing it in the system memory 52. The digital camera 100 according to the present embodiment has, for example, the following shooting modes as shooting modes included in the still image recording mode.

Auto mode: A mode in which various parameters of the camera are automatically determined by a program incorporated in the digital camera 100 based on the measured exposure value.
Manual mode: A mode in which the user can freely change various camera parameters.
Scene mode: A combination of shutter speed, aperture value, strobe lighting, sensitivity setting, etc. suitable for the shooting scene is automatically set.

The scene mode further includes the following modes, for example.
Portrait mode: A mode that specializes in portrait photography by blurring the background and making people stand out.
Night scene mode: A mode specialized for night scenes in which a person is flashed and the background is recorded at a slow shutter speed.
Landscape mode: A mode specialized for wide landscape scenes.
Night & Snap Mode: A mode suitable for taking beautiful night views and people without a tripod.
Kids & Pet Mode: A mode that allows you to take pictures of kids and pets that move around without missing a photo opportunity.
Fresh green & autumn leaves mode: Mode suitable for shooting trees and leaves of fresh greens in vivid colors.
Party mode: A mode that shoots in a color faithful to the subject while suppressing camera shake under a fluorescent light bulb.
Snow mode: A mode in which a person does not darken even when the snow scene is in the background, and leaves no blue.
Beach mode: A mode in which people can shoot without darkness even on the surface of the sea or sand where the sunlight is strongly reflected.
Fireworks mode: A mode for shooting fireworks vividly with optimal exposure.
Aquarium mode: A mode to set sensitivity, white balance, and color suitable for shooting fish in an indoor aquarium.
Underwater mode: A mode in which the white balance is set to be optimal for underwater, and the image is shot with a hue that reduces bluishness.
Diorama-like mode: A mode with image effect processing that blurs the top and bottom of the specified range to make it look like a long distance. For example, this is a mode described in Japanese Patent Application No. 2010-024602.

  When the shooting mode is determined, in subsequent S302, the system control unit 50 performs through display for displaying the image data from the imaging unit 22. The through display is a display (electronic viewfinder) that displays an image captured by the image capturing unit 22 on the display unit 28 as a substantially real-time moving image without being recorded on the recording medium 200. You can check the corners and measure the shooting timing. In the through display (electronic viewfinder) in S302, the image is displayed with the aspect ratio set for still image recording. At this time, in a manner similar to S405 described later, for example, a display showing the aspect ratio is performed using a pillar box or side black.

  In step S <b> 303, the system control unit 50 determines whether the remaining capacity of the power supply unit 30 configured by a battery, the presence / absence of the recording medium 200, and the remaining capacity has a problem in the operation of the digital camera 100. Determine using. If there is a problem, the process proceeds to S304, and the system control unit 50 performs a predetermined warning display with an image or sound using the display unit 28 or the like, and returns the process to S301. If there is no problem in the state of the power supply unit 30 and the recording medium 200, the process proceeds to S305.

  In step S305, the system control unit 50 determines whether a shooting mode switching operation has been performed. The shooting mode switching operation is an operation for switching the currently set shooting mode to another shooting mode from among the auto mode, manual mode, and various scene modes in the still image recording mode. This is performed by operating the operation unit 70, opening a shooting mode change menu screen or the like, and selecting an arbitrary shooting mode. If it is determined that the shooting mode switching operation has been performed, the process proceeds to S306, and if not, the process proceeds to S307. In step S306, the system control unit 50 changes the shooting mode according to the shooting mode switching operation.

  In step S <b> 307, the system control unit 50 determines whether the current shooting mode is a mode that requires position-added image effect processing. The mode that requires image effect processing with position designation is a mode in which image effect processing is performed on a partial area of a captured image based on an area designated by the user. For example, the above-described diorama-like mode, which is one of the scene modes, corresponds to such an image effect process with position designation. If it is determined that the image effect processing with position specification is necessary (for example, if it is determined that the current shooting mode is a diorama-like mode), the processing proceeds to S308. If not, the processing proceeds to S311.

  In step S308, the system control unit 50 performs image effect processing based on a specified partial area (hereinafter, also referred to as an image effect position) of a captured image (here, a through image). For example, in the diorama style mode, a process of blurring the outside of a specified part of the region (range) is performed. In step S <b> 309, the system control unit 50 determines whether an operation for changing the image effect position designated for image effect processing has been performed via the operation unit 70. If it is determined that an operation for changing the image effect position has been performed, the process proceeds to S310, and if it is determined that the operation has not been performed, the process proceeds to S311. In S310, the system control unit 50 changes the image effect position in accordance with an operation for changing the image effect position, and records the changed position in the nonvolatile memory. Then, based on the changed image effect position, image effect processing is performed on the captured image (here, a through image).

  In step S311, the system control unit 50 determines whether or not there has been a change operation for changing the basic moving image quality setting. If there is an operation for changing the basic moving image quality setting, the process proceeds to S312; otherwise, the process proceeds to S315. The change operation of the basic moving image quality setting is an operation of selecting an arbitrary image quality by operating the operation unit 70 to open a moving image quality change menu or the like (displayed on the display unit 28). In the image quality change menu, for example, HD image quality (1280 × 720 pixels, aspect ratio 16: 9) / SD image quality (640 × 480 pixels, aspect ratio 4: 3) / mini image quality (320 × 240, aspect ratio 4: 3) Any image quality can be selected from the list. As described above, the moving image quality is associated with the aspect ratio.

  In step S312, the system control unit 50 determines whether or not the current shooting mode is a mode that requires position-specified image effect processing. This determination processing is the same as the processing in S307 described above. If it is determined that the current shooting mode is not a mode that requires image effect processing, the process proceeds to S313, and if it is determined that the image effect processing is necessary, the process proceeds to S314.

  In step S <b> 313, the system control unit 50 changes the basic moving image quality setting according to the change operation of the basic moving image quality setting, and records the changed basic moving image quality setting in the nonvolatile memory 56. In S314, the system control unit 50 invalidates (ignores) the change operation of the basic moving image quality setting. At this time, an indication that the operation is invalid may be displayed on the display unit 28. This is because in the still image recording mode in which the image effect processing with position designation is necessary, when moving image shooting is performed by operating the moving image button 63, the image quality of the moving image is based on the aspect ratio set for the still image. This is because the image quality is automatically set. In this case, even if the basic video image quality setting is changed, it is not reflected at that time. Therefore, in order to prevent the user from being confused, the digital camera 100 according to the present embodiment performs such an operation for changing the basic video image quality setting. I am trying not to do it.

  Next, in S315, the system control unit 50 performs face detection for detecting whether or not a human face is present in the through-displayed image signal. When a human face is detected in the face detection process, the system control unit 50 uses the position coordinates, size (width, height), number of detections, reliability coefficient, etc. detected in the image signal as face information. Store in the memory 52. When a face is not detected in the face detection process, 0 is set in areas such as position coordinates, size (width, height), detected number, reliability coefficient, etc. in the system memory 52.

  Subsequently, in S316, the system control unit 50 determines whether or not the user has performed an aspect ratio switching operation. If it is determined that an aspect ratio switching operation has been performed, the process proceeds to S317, and the system control unit 50 performs an aspect ratio switching process. The aspect ratio switching operation is, for example, an operation for opening an aspect ratio switching menu and selecting an arbitrary aspect ratio when the user operates the operation unit 70. Selectable aspect ratios include 4: 3, 3: 2, 16: 9, 1: 1, and the like. In addition, when the current shooting mode is a mode that requires image effect processing with position designation (for example, a diorama-like mode), an aspect ratio (4: 3 and 16: It is recommended to limit the options to 9). Details of the aspect ratio switching process will be described later with reference to FIG. When S317 ends, the process proceeds to S318.

  Subsequently, in S318, the system control unit 50 determines whether or not the first shutter switch signal SW1 is ON (photographing preparation instruction reception). If the first shutter switch signal SW1 is OFF, the process proceeds to S319. On the other hand, if the first shutter switch signal SW1 is ON, the process proceeds to S321.

  In S <b> 319, the system control unit 50 determines whether or not there is a moving image shooting instruction by operating the moving image button 63. If there is a moving image shooting instruction from the moving image button 63, the process proceeds to S320. If there is no shooting instruction, the process returns to S305 and the above-described process is repeated. In S320, the system control unit 50 performs moving image button shooting processing (moving image shooting processing performed by operating the moving image button 63). The moving image button shooting process will be described later with reference to FIG.

  In S321, the system control unit 50 performs a shooting preparation operation. The system control unit 50 performs a distance measurement process to focus the photographing lens 103 on the subject (autofocus process), and performs a photometry process to determine an aperture value and a shutter speed (exposure determination process). In the photometric process, a flash is set if necessary. At this time, if a face is detected in S315, it is possible to perform face AF for performing distance measurement within the detected face range.

  Next, in S322 and S323, the system control unit 50 determines ON / OFF states of the first shutter switch signal SW1 and the second shutter switch signal SW2. If the second shutter switch signal SW2 is turned on while the first shutter switch signal SW1 is turned on, the process proceeds from S322 to S324. When the first shutter switch signal SW1 is turned off (when the second shutter switch signal SW2 is not turned on and the first shutter switch signal SW1 is also released), the process returns from S323 to S305. Further, while the first shutter switch signal SW1 is ON and the second shutter switch signal SW2 is OFF, the processes of S322 and S323 are repeated.

  When the second shutter switch signal SW2 is turned on, in S324, the system control unit 50 sets the display state of the display unit 28 from the through display to the fixed color display state (for example, black display). In step S325, the system control unit 50 executes shooting processing with a set aspect ratio including exposure processing and development processing. In the exposure process, the image data obtained through the image pickup unit 22 and the A / D converter 23 is sent from the image processing unit 24 and the memory control unit 15 or directly from the A / D converter 23 to the memory control unit. 15 to the memory 32. In the development process, the system control unit 50 uses the memory control unit 15 and, if necessary, the image processing unit 24 to read the image data written in the memory 32 and perform various processes. At this time, if the mode requires image effect processing (including image effect processing with position designation), the image effect processing is performed on the image data. In addition, clipping with the set aspect ratio is also performed.

  Next, in S326, the system control unit 50 performs a quick review display of the image data obtained by the photographing process on the display unit 28. The quick review display is a process for displaying the image data on the display unit 28 for a predetermined time (review time) before recording on the recording medium after photographing the subject for confirmation of the photographed image. In step S327, the system control unit 50 executes a recording process in which the image data obtained by the imaging process is written as an image file on the recording medium 200.

  In S328, the system control unit 50 determines the ON / OFF state of the second shutter switch signal SW2. When the second shutter switch signal SW2 is ON, the determination of S328 is repeated to wait for the second shutter switch signal SW2 to be OFF. During this time, the quick review display is continued. That is, when the recording process of S327 is completed, the quick review display on the display unit 28 is continued until the second shutter switch signal SW2 is released. With this configuration, the user can carefully check the captured image data using the quick review display by continuing to fully press the shutter button 61. In S328, when it is determined that the second shutter switch signal SW2 is OFF, that is, when the fully pressed state is released by releasing the hand from the shutter button 61 or the like, the process proceeds to S329.

  In step S329, the system control unit 50 determines whether a predetermined review time for quick review display has elapsed. If the review time has not elapsed, the process waits for the review time to elapse. If the review time has elapsed, the process proceeds to S330.

  In S330, the system control unit 50 returns the display state of the display unit 28 from the quick review display to the through display state. With this processing, after the captured image data is confirmed by the quick review display, the display state of the display unit 28 is automatically switched to a through display state in which the image data from the imaging unit 22 is sequentially displayed for the next shooting. Become.

  In S331, the system control unit 50 determines whether the first shutter switch signal SW1 is ON / OFF. If the first shutter switch signal SW1 is ON, the process returns to S322, and if it is OFF, the process returns to S305. That is, when the shutter button 61 is half-pressed (the first shutter switch signal SW1 is ON), the system control unit 50 prepares for the next shooting (S322). On the other hand, if the shutter button 61 has been released (the first shutter switch signal SW1 is OFF), the system control unit 50 ends the series of shooting operations and returns to the shooting standby state (S305).

<< Aspect ratio switching process (S317) >>
FIG. 4 is a flowchart of the aspect ratio switching process, showing details of the process in S317 of FIG. 3A described above. Each process in the aspect ratio switching process is realized by the system control unit 50 expanding and executing a program stored in the nonvolatile memory 56 or the like in the system memory 52.

  In step S401, the system control unit 50 determines whether or not the aspect ratio selected by the aspect ratio switching operation is the same as the aspect ratio before switching. If the selected aspect ratio is different from the aspect ratio before switching, that is, if the aspect ratio is changed, the process proceeds to S402. On the other hand, when the aspect ratio selected by the aspect ratio switching operation is the same as the aspect ratio before switching, the aspect ratio is not changed and the process is terminated.

  In S <b> 402, the system control unit 50 changes the aspect ratio of the still image to the aspect ratio selected by the aspect ratio switching operation, and records the changed aspect ratio in the nonvolatile memory 56. Next, in S404, the system control unit 50 displays the aspect ratio recorded in S403 by displaying, for example, a pillar box or side black on the through image displayed on the display unit 28. The pillar box and side black may be made semi-transparent or display only with a frame so that the aspect ratio can be identified.

  In step S <b> 404, the system control unit 50 determines whether the current shooting mode is a mode that requires image effect processing with position designation. This is the same as the process of S307 described above. If it is determined that the current shooting mode is not a mode that requires position-designated image effect processing, the aspect ratio change processing ends, and if it is determined that the mode requires position-designated image effect processing, processing is performed. Advances to S405.

In step S <b> 405, the system control unit 50 calculates a position y <b> 2 corresponding to the image effect position set with the aspect ratio before change in the aspect ratio after change. For example, when the position of the image effect position in the vertical direction (y direction) is designated, the position y2 is calculated by the following (Equation 1).
y2 = Y2 * y1 / Y1 (Formula 1)
However,
-Vertical size of the entire image at the aspect ratio before change: Y1
The position in the Y direction with respect to the entire image at the aspect ratio before change at the center of the image effect position set at the aspect ratio before change: y1
-The vertical size of the entire image at the changed aspect ratio: Y2
The position of the center of the image effect position set with the changed aspect ratio in the Y direction with respect to the entire image with the changed aspect ratio: y2
In this way, the image effect position is automatically corrected in accordance with the change in aspect ratio. When the position in the horizontal direction (X direction) of the image effect position is designated, the image effect position is corrected by performing the same calculation as in (Expression 1) above with respect to the X direction.

  In S <b> 406, the system control unit 50 starts the display on the display unit 28 by applying an image effect on the image (here, a through image) displayed on the display unit 28 based on the image effect position information calculated in S <b> 405. . In S407, the system control unit 50 records the moving image quality corresponding to the changed still image aspect ratio set in S402 in the nonvolatile memory 56 as the modified moving image quality. These modified movie image quality settings are recorded separately from the basic movie image quality settings described above, and are temporarily used when a movie is shot in a mode that requires position-added image effect processing. Is done. Note that the moving image quality corresponding to the still image aspect ratio is the above-mentioned SD image quality for still image aspect ratio 4: 3, and the aforementioned HD image quality for still image aspect ratio 16: 9. Correspond. In this way, among the still image recording modes, in the mode that requires image effect processing, the aspect ratio of the still image and the aspect ratio of the moving image are the same.

[Movie button shooting process]
FIG. 5 shows a flowchart of the moving image button shooting process. The moving image button shooting process is the details of the process of S320 in FIG. 3B described above. Each processing in this processing is realized by the system control unit 50 expanding and executing a program stored in the nonvolatile memory 56 or the like in the system memory 52.

  In step S501, the system control unit 50 determines whether or not the current shooting mode is a mode that requires an image effect process with position designation. This is the same as the process of S307 in FIG. 3A. If it is determined that the current shooting mode is a mode that requires image effect processing with position designation, the process proceeds to S502, and if it is not, the process proceeds to S503.

  In step S <b> 502, the system control unit 50 starts recording a moving image (moving image shooting) with a modified moving image quality setting that is recorded in the nonvolatile memory 56 and has a moving image quality corresponding to the still image aspect ratio. The captured moving image is recorded on the recording medium 200. On the other hand, in step S <b> 503, the system control unit 50 starts recording a moving image with the basic moving image quality setting recorded in the nonvolatile memory 56.

  In step S504, the system control unit 50 determines whether there is an instruction to end moving image shooting. If there is an end instruction, the process proceeds to S505, and if not, moving image shooting is continued. Note that the moving image shooting end instruction is an operation of pressing the moving image button 63 again or shifting to another mode such as a playback mode. In step S505, the system control unit 50 ends moving image recording, performs moving image recording end processing such as processing to close a moving image file generated on the recording medium 200 by recording the moving image, and ends the moving image button shooting processing. .

  Thus, in moving image shooting by operating the moving image button 63, it is determined whether or not the current still image recording mode is a mode that requires image effect processing. If the current still image recording mode is a mode that requires image effect processing, the still image aspect ratio that matches the aspect ratio of the still image recording is used instead of the basic movie image quality set by the user for the movie. The movie is recorded with the corresponding modified movie image quality. This prevents the position where the image effect is applied from becoming unnatural because the aspect ratio of the recorded video is different from the through image with respect to the image effect position set while viewing the user through image. Can do.

[Movie recording mode processing]
FIG. 6 shows a flowchart of the moving image recording mode process. The moving image recording mode process described below is the details of the process of S206 in FIG. Each processing in this processing is realized by the system control unit 50 expanding and executing a program stored in the nonvolatile memory 56 or the like in the system memory 52.

  First, in step S <b> 601, the system control unit 50 performs through display on the display unit 28. In step S602, the system control unit 50 determines whether or not the user has changed the basic moving image quality setting operation. This process is the same process as S311 of FIG. 3A described above. If there is an operation for changing the basic moving image quality setting, the process proceeds to S603, and if not, the process proceeds to S604. In step S <b> 603, the system control unit 50 changes the basic moving image quality setting according to the change operation of the basic moving image quality setting, and records the changed basic moving image quality setting in the nonvolatile memory 56.

  In step S604, the system control unit 50 determines whether there is a moving image recording instruction. If there is an instruction to record a moving image, the process proceeds to S605, and if not, the process proceeds to S608. The moving image recording instruction is performed by operating the shutter button 61 or the moving image button 63. In S608, it is determined whether or not there is an operation for ending the moving image recording mode (an operation for changing to another mode, an operation for turning off the power, etc.). If there is no end operation, the process returns to S601. If there is an end operation, the moving image recording mode process ends.

  In step S <b> 605, the system control unit 50 starts recording a moving image with the basic moving image quality setting recorded in the nonvolatile memory. In step S606, the system control unit 50 determines whether there is an instruction to end the recording of the moving image. If there is no end instruction, recording (shooting) of the moving image is continued, and if there is an end instruction, the process proceeds to S607. In step S <b> 607, the system control unit 50 ends moving image recording, and performs moving image recording end processing such as processing for closing a moving image file generated on the recording medium 200 by recording the moving image. Thereafter, the process returns to S601.
