  FIG. 2 is a block diagram illustrating a configuration example of the digital camera 100 according to the present embodiment.

  In FIG. 2, an image pickup unit 22 is an image pickup element constituted by a CCD, a CMOS element, or the like that converts an optical image into an electric signal. The A / D converter 23 converts an analog signal into a digital signal. The A / D converter 23 is used to convert an analog signal output from the imaging unit 22 into a digital signal.

  The image processing unit 24 performs resizing processing such as predetermined pixel interpolation and reduction and color conversion processing 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 (auto focus mode) processing, AE (automatic exposure) processing, and EF (flash pre-flash) 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 (imaging range) 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 as an electronic viewfinder. It functions and can display through images (live view images).

  The nonvolatile memory 56 is a memory as an electrically erasable / recordable recording medium, 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 is a computer program for executing various flowcharts described later in the present embodiment.

  The system control unit 50 controls the entire digital camera 100. By executing the program recorded in the non-volatile memory 56 described above, each process of the present embodiment to be described later is realized. A RAM is used as the system memory 52. In the system memory 52, constants and variables for operation of the system control unit 50, programs read from the nonvolatile memory 56, and the like are expanded.

  The system timer 53 is a time measuring unit that measures the time used for various controls and the time of a built-in clock.

  The mode switch 60, the shutter button 61, and the operation unit 70 are operation means 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 shooting mode, a reproduction mode, and the like. The mode changeover switch 60 can directly switch to one of these modes included in the menu screen. Alternatively, after switching to the menu screen once by the mode switch 60, it may be switched to any of these modes included in the menu screen using another operation member. The first shutter switch 62 is turned on when the 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. The first shutter switch signal SW1 can be set to start operations such as AF (auto focus) processing, AE (auto exposure) processing, AWB (auto white balance) processing, and EF (flash pre-flash) processing. .

  The second shutter switch 64 is turned ON when the operation of the shutter button 61 is completed, that is, when it is fully pressed (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.

  A magnification change button 67 (enlarge button 67a, reduce button 67b) is also included in the operation unit 70, and changes the size of the image displayed on the display unit 28. In response to pressing of the magnification change button 67, the system control unit 50 changes the area to be read out of the imaging unit 22 so that the size of the image displayed on the display unit 28 is changed.

  When the controller wheel 73 is rotated, an electrical pulse signal is generated according to the operation amount, and the system control unit 50 controls each unit of the digital camera 100 based on the pulse signal. 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 number of times of switching of the enlargement area may be determined according to the angle or the number of rotations according to the rotation operation to the controller wheel 73 (switching once by a predetermined amount of rotation operation), or one continuous rotation operation may be performed. You may make it switch an expansion area | region once every time it performs (it accepts switching). 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 switch 72 switches between power on and power off.

  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 non-volatile recording medium such as a memory card for recording captured images, and includes a semiconductor memory, an optical disk, a magnetic disk, and the like.

  The communication unit 54 is connected to an external device or a network via a wireless or wired cable, and transmits and receives video signals, audio signals, and the like. The communication unit 54 can also be connected to a wireless LAN (Local Area Network) or the Internet. The communication unit 54 can transmit an image captured by the imaging unit 22 (including a through image) and an image recorded on the recording medium 200, and can receive image data and other various types of information from an external device. it can.

  As one of the operation units 70, a touch panel 70a capable of detecting contact with the display unit 28 is provided. The touch panel and the display unit 28 can be configured integrally. For example, the touch panel is configured such that the light transmittance does not hinder the display of the display unit 28, and is attached to the upper layer of the display surface of the display unit 28. Then, the input coordinates on the touch panel are associated with the display coordinates on the display unit 28. Thereby, it is possible to configure a GUI (graphical user interface) as if the user can directly operate the screen displayed on the display unit 28.

  In the digital camera 100 described above, it is possible to perform photographing using central one-point AF or face AF. Central one-point AF is to perform AF on one central position in the shooting screen. Face AF is to perform AF on the face in the shooting screen detected by the face detection function.

  The face detection function will be described. The system control unit 50 sends the face detection target image data to the image processing unit 24. Under the control of the system control unit 50, the image processing unit 24 applies a horizontal bandpass filter to the image data. In addition, under the control of the system control unit 50, the image processing unit 24 applies a vertical bandpass filter to the processed image data. By these horizontal and vertical band pass filters, edge components are detected from the image data.

  Thereafter, the system control unit 50 performs pattern matching on the detected edge components, and extracts a candidate group of eyes, nose, mouth, and ears. Then, the system control unit 50 determines an eye pair that satisfies a preset condition (for example, distance between two eyes, inclination, etc.) from the extracted eye candidate group. Narrow down the candidate group of only those with. Then, the system control unit 50 associates the narrowed-down eye candidate group with other parts (nose, mouth, ears) that form the corresponding face, and passes a preset non-face condition filter. , Detect the face. The system control unit 50 outputs the face information according to the face detection result, and ends the process. At this time, feature quantities such as the number of faces are stored in the system memory 52.

  As described above, it is possible to analyze the image data displayed or reproduced and display the live view, extract the feature amount of the image data, and detect the subject information. In the present embodiment, face information is taken as an example of subject information. However, subject information includes various information such as red-eye determination, eye detection, eye-brow detection, and smile detection. Also, by changing the detection method according to the subject information to be detected, it is possible to detect a specific subject other than the face. For example, an animal face, a child's face, a hand, a moving object, or the like can be detected.

  Note that the face AE, the face FE, and the face WB can be performed simultaneously with the face AF. The face AE is to optimize the exposure of the entire screen according to the brightness of the detected face. The face FE is to perform flash dimming around the detected face. The face WB is to optimize the WB of the entire screen according to the detected face color.

  The display process in the shooting mode will be described with reference to the flowchart of FIG. This flowchart starts when the digital camera 100 is turned on and can be displayed on the display unit 28. This process is realized by developing a program recorded in the nonvolatile memory 56 in the system memory 52 and executing it by the system control unit 50.

  In step S301, the system control unit 50 determines whether shooting is on standby. If it is determined that shooting is on standby, the process proceeds to S303. If not, the process proceeds to S302. Waiting for shooting means that one of the shooting modes for shooting movies is set, and shooting of a movie (with recording in a non-volatile memory) starts when shooting is instructed. Is done. In addition to waiting for shooting, there are playback during image playback and menu settings for setting items.

  In S302, the system control unit 50 performs other processing. The other processing is processing such as reproduction and menu setting as described above in S301. Even during playback or menu setting, if a shooting instruction is given, a moving image or still image is shot, and then the process proceeds to shooting standby (S303), and a live view image is displayed on the display unit.

  In S <b> 303, the system control unit 50 displays the live view image obtained from the imaging unit 22 on the display unit 28. Assume that the size of the image displayed at this time is the reference size. If it is larger than the size of the image displayed in S303, it is enlarged, and if it is smaller, it is reduced. In the present embodiment, the live view image is displayed with the same size as the display unit 28 and the same aspect ratio.

  In S304, the system control unit 50 determines whether the grid display setting is ON. Whether the grid display setting is ON or OFF is stored in the nonvolatile memory 56. If the grid display setting is set to ON, the process proceeds to S305, and if not, the process proceeds to S306.

  In S <b> 305, the system control unit 50 displays a grid (grid line) on the display unit 28. As shown in FIG. 4B, the grid 402 is displayed so as to be superimposed on the live view image 401 displayed on the display unit 28 in S303. The grid 402 is a line that divides the vertical and horizontal lengths of the live view image 401 or the display unit 28 into three, and is a 3 × 3 (divides the live view image 401 into nine regions). In addition to 3 × 3, the grid includes 6 × 4 (the image is divided into a predetermined number), a golden ratio, and the like, and the user sets a suitable grid according to the composition of the image to be taken and the arrangement of the subject. Can do.

  In S <b> 306, the system control unit 50 displays a live view image without displaying a grid on the display unit 28. A live view image 401 displayed on the display unit 28 in S303 as shown in FIG. 4A is displayed. However, when an aspect marker indicating an aspect ratio other than the grid or a safety line indicating a range displayed during playback is set, the aspect marker and the safety line are superimposed on the live view image 401. indicate. When the grid display setting is OFF, or when the grid display setting is OFF and the aspect marker and safety line display settings are ON, the user is going to shoot with a composition centered on the main subject. Probability is high.

  In S307, the system control unit 50 determines whether or not a face has been detected as a result of performing face detection to determine whether or not the displayed live view image has a face. If it is determined that a face has been detected, the process proceeds to S308, and if not, the process proceeds to S309. The face detection may be performed not only in S307 but also every predetermined time such as 1 second or 2 seconds. The specific subject to be detected is not limited to the face, and the user may change the subject to be detected according to the subject to be photographed.

  In S <b> 308, the system control unit 50 generates the coordinates of the position where the face is detected as the coordinate information of the face position, and stores it in the system memory 52. The coordinates are assumed to have the X axis in the right direction and the Y axis in the downward direction with the upper left of the display unit 28 as the origin (0, 0).

  In step S309, the system control unit 50 determines whether or not the grid display setting has been switched. The grid display setting (grid setting) can also be performed on the menu screen. It is also possible to set a grid display (not shown) displayed in response to pressing of the setting item display button 77. If it is determined that the grid display setting has been switched, the process proceeds to S310, and if not, the process proceeds to S310.

  In S310, the system control unit 50 determines whether or not the grid display setting before the grid display setting is switched in S309 is ON. If it is determined that the grid display setting is ON, the process proceeds to S312; otherwise, the process proceeds to S311.

  In S <b> 311, the system control unit 50 sets the grid display setting to ON, and records that the nonvolatile memory 56 is set to ON. Also, from the state in which the live view image 401 in FIG. 4A is displayed, the grid 402 is displayed so as to be superimposed on the display unit 28 on the live view image 401 as shown in FIG. 4B.

  In S <b> 312, the system control unit 50 sets the grid display setting to OFF and records that it is set to OFF in the nonvolatile memory 56. In addition, the grid displayed on the display unit 28 is hidden.

  In S313, the system control unit 50 determines whether or not an operation for ending the shooting mode has been performed. The ending operation is an operation that is switched to the playback mode, menu setting, or the like when the power of the digital camera 100 is turned off, and is an operation that is not in the moving image shooting mode. However, the end operation is not performed even if the operation for switching to the still image shooting mode is performed. If it is determined that there has been an end operation, the shooting mode processing ends, and if not, the process proceeds to S314.

  In step S314, the system control unit 50 determines whether an enlargement display instruction has been given. The enlargement display instruction can be performed by pressing the enlargement button 67a (accepting an instruction for enlargement display) (accepted when the enlargement button 67a is pressed). From the size of the image before the enlargement instruction operation is performed, the enlargement magnification is determined according to the number of times the enlargement button 67a is pressed. The magnification may be determined according to the number of operations, such as 5 times when the enlargement instruction operation is performed once, 10 times when it is performed twice. Note that the shooting range is optically enlarged or reduced according to the rotation operation of the zoom lever 63.

  In S <b> 315, the system control unit 50 determines whether the grid display setting recorded in the nonvolatile memory 56 is ON. If it is determined that the grid display setting is ON, the process proceeds to S316; otherwise, the process proceeds to S318.

  In S <b> 316, the system control unit 50 enlarges the area centered on the grid intersection that was the center of the enlarged area when the enlarged display was performed with the grid intersection just before the grid intersection displayed on the display unit 28. And displayed on the display unit 28. As will be described later, the grid intersection that was the center of the enlarged area in the enlarged display immediately before the grid intersection when the grid is displayed is stored in the memory 32 (enlarged display in the immediately following grid display). Used in). Here, the enlarged display of the area centered on the grid intersection point 403 will be described on the assumption that the enlarged display centered on the grid intersection point 403 was performed immediately before the grid intersection point 403. In addition, when the grid intersection that is the center of the enlarged display is not recorded in the memory 32 (the first enlargement in a state where the grid is displayed after the power is turned on), the area centered on the grid intersection 403 is enlarged and displayed. Shall be. The grid intersection 403 is at the upper left of the plurality of grid intersections, and in the case of the first enlargement with the grid displayed, the grid intersection at the upper left of the plurality of grid intersections is thus enlarged. . However, it is not necessarily the grid intersection at the upper left, but may be at the upper right or the lower left. In continuous shooting with the grid displayed, it is likely that the user will often shoot with the same composition, so there is a high possibility that the main subject is placed at the grid intersection displayed as the center in the previous enlarged display . Therefore, if the enlargement display is performed around the center grid intersection that has been enlarged and displayed immediately before the enlargement display is instructed, there is a high possibility that the main subject can be enlarged without switching the enlargement area. An enlarged area 503 in FIG. 5A is a display example of the live view image 401 in which the area centered on the grid intersection 403 is enlarged. The enlarged area 503 is enlarged and displayed so that the pixels in the area corresponding to the enlarged area 503 in the imaging unit 22 are read and displayed according to the size of the display unit 28. In the normal display and the enlarged display, the reading range of the imaging unit 22 is different, and the range in the enlarged display is smaller. Since the displayed size is displayed in accordance with the size of the same display unit 28 in the normal display and the enlarged display, the enlargement magnification becomes larger when the enlarged display is performed. The user can make settings such as focus and exposure for the main subject located in the enlarged display area. As described above, when the user takes a suitable composition (a composition in which the main subject is located at the grid intersection), the main subject is enlarged simply by giving an enlargement display instruction without performing an operation of moving the enlargement area. Since it is displayed, you can quickly adjust the focus and exposure. An enlarged area frame 413 shown in FIG. 4C is a frame for explaining the area displayed in FIG. 5A in the live view image 401 and the area enlarged in S316, and is actually displayed. It is not displayed on the part 28. In the live view image 401, an area within the enlarged area frame 413 is enlarged and displayed. Similarly, the enlarged area frame 414 in FIG. 4D and the enlarged area 504 in FIG. 5B, the enlarged area frame 415 in FIG. 4E, the enlarged area 505 in FIG. 5C, and FIG. ) Enlarged region frame 416 and enlarged region 506 in FIG. 5D also show enlarged images corresponding to the enlarged display region. Note that the enlargement ratio of the enlargement area displayed for the live view image 401 in FIGS. 4 and 5 is an example, and is not limited to this.

  In step S <b> 317, the system control unit 50 displays a guide such as an icon 501 and a frame 502 relating to the enlarged display area on the display unit 28. An icon 501 in FIG. 5A is an icon for simply indicating information related to an enlarged image, and the face in the live view image 401 is based on the acquired coordinate information of the face position in S308. Indicates the position. The position of the mark indicating the face position in the icon 501 is displayed so as to correspond to the coordinates of the face position generated in S308. The icon 501 allows the user to grasp where the face is in the live view image 401. A frame 502 is a frame icon for indicating which region of the live view image 401 is displayed in an enlarged manner. In FIG. 5A, the region around the upper left of the live view image 401 is displayed in an enlarged manner. I understand. The size of the frame 502 occupied by the icon 501 corresponds to the size of the region occupied by the live view image 401 of the enlarged region 503, and the user can grasp the size of the enlargement rate. In addition, in the icon 501 and the frame 502 in FIG. 5A, a person that is not included in the currently displayed enlarged area so that two persons are present on the right side of the currently displayed enlarged area 503. It is possible to grasp where (the detected face) is located. Further, the current enlargement area may be switched to another enlargement area with reference to the position of the person.

  In S318, the system control unit 50 enlarges and displays an area centered on the center of the image (imaging surface). An enlarged area 507 in FIG. 5E is a display example when the area of the center (center coordinate 407) of the live view image 401 is enlarged and displayed. An enlarged area frame 417 in FIG. 4G is a frame indicating an enlarged area when the area at the center of the live view image 401 is displayed in an enlarged manner, not at the intersection of the grids. FIG. An enlarged region 507 when the center of the image is enlarged is shown. The enlarged area frame 417 is a frame for explaining the area displayed in an enlarged manner, and is not actually displayed on the display unit 28. The enlargement ratio when the grid is not displayed is smaller than the enlargement ratio when the grid is displayed. When the grid is not displayed, there is a high possibility that there are multiple main subjects in the center of the image or a wide range in the center of the image, and it is a partial area such as an area centered at the grid intersection. It is better to magnify the entire center than to magnify it. Note that the magnification may be the same as that when the grid is displayed.

  In S319, the system control unit 50 displays a guide such as an icon 501 and a frame 502 on the enlarged display area on the display unit 28 as in S317. The area enlarged and displayed in S317 is an area centered on the grid intersection point 403. However, in S318, the area is centered on the center coordinate 407 of the live view image 401. Therefore, the position of the frame 502 indicating the enlarged area is shown in FIG. It is different from the position of 5 (a).

  In S320, the system control unit 50 determines whether or not the rotation operation to the controller wheel 73 has been performed for a predetermined amount or more and the enlargement area is switched (switching instruction). If it is determined that the enlargement area has been switched, the process proceeds to S321; otherwise, the process proceeds to S322.

  In S321, the system control unit 50 enlarges and displays a region centered on a grid intersection that is different from the grid intersection that becomes the center of the enlarged region enlarged and displayed in S316 or immediately preceding S320. In the present embodiment, when the area centered on S316 or the immediately preceding grid intersection point 403 is enlarged and displayed, the area centered on the position of the grid intersection point 404 is enlarged and displayed. Further, when the area centered on the grid intersection 404 is displayed in an enlarged manner, the area centered on the grid intersection 405 is enlarged, and when the area centered on the grid intersection 405 is displayed enlarged, the grid intersection point is displayed. It is assumed that an area centered at 406 is enlarged. In the present embodiment, the enlarged region is repeatedly switched in the order of upper left, upper right, lower left, and lower right of the grid intersection. Each time the enlargement area is switched, the grid intersection stored in the memory 32 and serving as the center of the enlargement area displayed immediately before is updated.

  In S322, the system control unit 50 determines whether there is an instruction to stop the enlarged display. The instruction to stop the enlargement display is an instruction to perform the normal display, and when the enlargement button 67a is pressed once, the instruction can be performed by pressing the reduction button 67b once. When the enlargement button 67a has been pressed N times, when the reduction button 67b is pressed up to the (N-1) th time, the image is enlarged as compared with the normal display image, and the Nth reduction operation is enlarged. It will be an operation to quit. Note that, regardless of how many times the enlargement button 67a has been pressed (regardless of the enlargement magnification), it is possible to return to the reference size (cancel enlargement) by pressing the reduction button 67b once.

  In S323, the system control unit 50 determines whether or not an enlargement area movement operation has been performed by pressing the cross key 74 to each key. If it is determined that there has been an operation for moving the enlarged area, the process proceeds to S324; otherwise, the process proceeds to S325.

  In S324, the system control unit 50 moves the enlarged region according to the moving direction and the moving amount according to the moving operation. The moving direction and moving amount of the enlargement area (the direction and amount of shifting the display area while keeping the enlargement magnification constant) are determined according to the direction corresponding to each key to the cross key 74 and the number of times of pressing. It is assumed that the robot moves by a predetermined distance in response to a single press on each key (reception of movement once). If the right key 74c, the area moved in the right direction by the distance corresponding to the number of presses is displayed, and if the left key 74, the area moved in the left direction by the distance corresponding to the number of presses is displayed. Even if the displayed enlarged area moves, the size of the enlarged area and the enlargement rate do not change. The enlarged area 601 in FIG. 6A is displayed on the display unit 28 when the right key 74c of the cross key 74 is pressed and the enlarged area is moved from the state in which the enlarged area 503 in FIG. 5A is displayed. The enlarged image displayed on is shown. Since the position of the frame 502 in the icon 501 in FIG. 6A is on the right side of the position of the frame 502 in the icon 501 in FIG. 5A, the displayed enlarged area has moved to the right. I understand. As shown in FIG. 6A, a grid 402 may be superimposed on the enlarged image, and the user can determine the position of the center of the composition or the main subject from the position of the grid intersection. Can be confirmed. In addition, when the moving operation is performed, the distance moved is known. FIG. 6B shows an enlargement area 602 displayed when the enlargement area is moved in the right direction by pressing the right key 74c from the enlargement area 601 in FIG. 6A. If the rotation operation to the controller wheel 73 in S320 is performed in a state where the enlarged area 602 in FIG. 6B is displayed on the display unit 28, the enlarged area is switched to the enlarged area 504 shown in FIG. Even if the enlargement area is moved, if the enlargement area switching operation is performed, the area centered on the next grid intersection is enlarged, so the user can move the main subject at the grid intersection to the fine enlargement area. It is possible to switch and confirm immediately without moving.

  In S325, the system control unit 50 determines whether or not the shutter button 61 is half-pressed and the first shutter switch signal SW1 is on. If it is determined that the first shutter switch signal SW1 has been turned on, the process proceeds to S326, and if not, the process proceeds to S320.

  In S326, the system control unit 50 stops the enlarged display and hides the enlarged position guide of the icon 501 and the frame 502. That is, the live view image 401 that is not enlarged and displayed in the reference size displayed in S303 is displayed. In this way, when the user presses the shutter button 61 halfway to take a picture, when the enlarged display is stopped and the reference size is displayed, the user can confirm again that the whole picture to be photographed.

  In S327, the system control unit 50 determines whether or not the second shutter switch signal SW2 is turned on by fully pressing the shutter button 61. If it is determined that the second shutter switch signal SW2 is turned on, the process proceeds to S331, and if not, the process proceeds to S325.

  The processing of S328 to S330 described below is processing in the case where the enlargement display instruction is not issued in S314 and the shooting instruction is given without the enlarged display of the live view image 401 displayed in S303.

  In S328, the system control unit 50 determines whether or not the first shutter switch signal SW1 is turned on because the shutter button 61 is half-pressed similarly to S325. If it is determined that the first shutter switch signal SW1 is turned on, the process proceeds to S329, and if not, the process proceeds to S304.

  In step S329, the system control unit 50 focuses on the center position of the live view image 401. If the image is not enlarged, AF (autofocus) is performed at the center of the image. On the other hand, when the in-focus display confirms the in-focus state, the mode is switched to MF (manual focus mode), and the image is taken as it is at the adjusted in-focus position.

  In S330, the system control unit 50 determines whether or not the second shutter switch signal SW2 is turned on by full pressing of the shutter button 61 as in S327. If it is determined that the second shutter switch signal SW2 is turned on, the process proceeds to S331, and if not, the process proceeds to S328.

  In S331, the system control unit 50 starts moving image shooting. Here, moving image shooting is shooting of a moving image accompanied by recording on the non-volatile recording medium 200.

  In step S332, the system control unit 50 determines whether an instruction to end shooting has been issued. If it is determined that an instruction to end shooting has been issued, the process proceeds to S333, and if not, the process returns to S331.

  In S333, the system control unit 50 performs a moving image file end process. Processing is performed such that the created moving image file can be reproduced by performing attribute information, interframe information, thumbnail creation, compression processing, and the like of the moving image file. These pieces of information are stored in the recording medium 200 together with the moving image file.

  Note that the position to be focused in S329 is not limited to the center of the live view image 401, and may be a position detected as a human face, a position with a grid intersection, or the like.

  In the present embodiment, the shooting of moving images has been described. However, still images may be shot instead of moving images.

  Next, an enlarged display example in the case where the grid is 6 × 4 will be described with reference to FIGS. FIG. 6C shows a live view image 401 or a grid 603 that divides the vertical and horizontal lengths of the display unit 28 into 6 divisions and 4 divisions. The grid 603 is a (form) grid that divides the live view image 401 or the display unit 28 more finely than the grid 402. On the menu screen, the user can not only switch between displaying and hiding the grid, but can also select the type of grid. The grid intersection 604 is one of the grid intersections of the grid 603 and the center of the enlarged area 605 displayed in FIG. FIG. 6D shows a case where an area centered on the grid intersection 604 is enlarged and displayed immediately before. The larger the number of grids that the set grid divides the image, the larger the enlargement ratio (the area of the enlarged live view image becomes smaller). This is for enlarging the area centered on each grid intersection so that it can be easily confirmed, so that other grid intersections are not included in the enlarged area. Thus, by enlarging the area centered on each grid intersection, it becomes easier to confirm the focus and exposure of the main subject located at the grid intersection. However, when there are many grid intersections and the enlargement ratio becomes too large, grid intersections other than the center grid intersection need not necessarily be included in the enlarged region.

  As described above, according to the embodiment described above, the user can more easily enlarge and display the subject as the main subject. When the grid is displayed, the user is likely to place the main subject at the grid intersection, and when the grid is not displayed, the user is likely to place the main subject at the center of the image. Therefore, when the grid is displayed, the area centered on the grid intersection is displayed enlarged, and when the grid is not displayed, the center of the image is centered in response to the enlargement operation. Enlarge the area. In this manner, the area to be enlarged is changed depending on whether the grid is displayed or not, so that the area that the user wants to enlarge and the position of the subject change. In addition, when the grid is displayed, an area centered on another grid intersection is enlarged according to the switching of the enlarged area (the area or grid intersection that was enlarged immediately before is displayed). Zoom in on the area based on the information). Therefore, the subject that has been framed at the intersection of the grids can be easily displayed by the switching operation without performing the operation of moving the enlarged region after the enlarged display.

  In addition, since the area to be enlarged and the enlargement ratio are changed according to the grid type, the main subject located at the grid intersection can be easily confirmed even if the grid type is changed.

  When the grid is not displayed, the area centered on the center of the live view image is enlarged as shown in S318. However, the AF position, the focus adjustment position, and the face detected area are not necessarily the center. May be enlarged and displayed. In a specific AF mode including a face priority AF mode in which AF is performed with priority given to a face when a face is detected, the AF position or the face detected area may be enlarged and displayed. When the grid is displayed, it is considered that the user intends to take a picture taking into consideration the composition and the main subject is positioned at the intersection of the grid. On the other hand, when AF or face detection is performed without displaying the grid, it is considered that the main subject is positioned at the AF position or the face detected position. When the AF position is enlarged, it becomes easier for the user to confirm and adjust the focus, and when the face is detected, it becomes easier to take a picture without missing a photo opportunity if the facial expression of the person becomes easier to see.

  In this embodiment, the enlargement ratio is constant regardless of the position of the grid intersection in the live view image (the enlargement area remains constant while the enlargement area is switched), and the grid intersection is the center. is not. For example, if the enlargement ratio is small, for example, the area that is enlarged when it is centered on the grid intersection near the edge of the image, or the area to be enlarged exceeds the edge of the live view image, the enlargement ratio is set. You may enlarge it. Alternatively, the grid intersection may not be the center of the enlarged area but may be included in the enlarged area.

  Further, even when the grid is displayed, the touched portion and the in-focus position may be enlarged. When the grid is displayed, the touched part may be enlarged according to the touch operation performed, and the grid intersection may be enlarged when the enlargement button 67a is pressed. As described above, when the area to be enlarged and displayed is determined, the important part of the composition and the part that the user wants to check without being based on the composition can be easily enlarged and displayed. When the grid is displayed, the user can set whether to enlarge the area around the grid intersection or to enlarge the area based on the user's touch position or focus position according to the enlargement instruction. May be.

  In the present embodiment, when the enlargement instruction is given while the grid is displayed, the area centered on the intersection of the grid is enlarged, but this is not restrictive. These areas may be enlarged and displayed. That is, for example, when a nine-divided grid is displayed as shown in FIG. 4B, the upper left, lower right, and center areas partitioned by the grid in the live view image 401 may be displayed in an enlarged manner.

  It has been described that the enlargement display instruction is performed by the zoom lever 63, the enlargement area is switched by the controller wheel 73, and the movement of the enlargement area is performed by the cross key 74. However, the operation member corresponding to each instruction is not limited to this, and touch You may make it carry out by operation. If it is a touch operation, the enlargement area is switched according to the flick that moves the screen to play, and the touch moves to move on the touch panel while touching the screen. The area may be moved. Alternatively, the distance between two touched points may be enlarged by pinching out, and the distance between the two touched points may be reduced by pinching in. In addition, the number of times of switching the enlargement area may be determined according to the rotation angle and the number of rotations of the controller wheel 73, or the enlargement area may be switched once when a continuous rotation operation is performed once. It may be a thing.

  Note that it is not necessary to enlarge the image so as to match the size of the display unit 28, and the display area only needs to be a displayable range. Further, when the image is reduced, the image may be displayed in an area smaller than the size of the display unit 28.

  In addition, the enlargement display is canceled in S326 in response to the SW1 being turned on during the enlargement display. However, the enlargement display may not be necessarily canceled, but the enlargement display may be kept. If the enlarged display is kept after the SW1 is turned on, the main subject can be obtained by turning on the SW2 at a suitable timing while watching the state of the subject as the main subject (pressing the shutter button 61 halfway to fully). It is easy to shoot with a good expression and good timing.

  In the present embodiment, it has been described that the enlarged display is performed when the grid 402 is displayed, and the center of the enlarged display area is switched in order when the enlarged area is switched. It does not have to be. Also, the order of switching may not always be the same for each grid. The grid intersection of the area where the face is detected is displayed with priority, or the grid intersection of the area where the face is detected is prioritized. Then, it may be enlarged and displayed. In this embodiment, the operation member that switches the enlargement area is the controller wheel 73. However, when assigning an operation member that can instruct a direction such as a direction key, the operation member is in the corresponding direction. You may make it switch to an area | region.

[Modification of Embodiment]
In the above-described embodiment, the enlargement centered on the grid intersection has been described. In the modified example, a case where the user displays an auxiliary shooting line such as an aspect marker or a safety line, not limited to the grid intersection, will be described. In the above-described embodiment, when the grid display is not performed and the aspect marker and the safety line are displayed, the center of the image is enlarged. In this modification, when an enlargement instruction is given while an aspect marker or safety line is displayed, the area corresponding to the position where the aspect marker or safety line is displayed is enlarged instead of the center area of the image. explain.

  For the purpose of superimposing aspect markers and safety lines on the Live View image, the range of the image area recorded after shooting, or the range of the image area recorded when editing to the shooting auxiliary line To the user. Therefore, the subject on the inside of the aspect marker or safety line as viewed from the center of the live view image 401 is also displayed on a display device having a field of view of less than 100%, and it is highly possible that the subject will not be lost after editing. Some subjects may not be recorded. FIG. 6E shows a display example when the safety line 606 is displayed on the display unit 28 so as to be superimposed on the live view image 401. It is assumed that the inside of the safety line 606 is an image range that is displayed even on a display device having a field of view of less than 100% and is not likely to be lost after editing. The outside of the safety line 606 may be lost during display or after editing. However, by displaying the safety line 606, the photographer can visually recognize whether the subject is within the range, and thus it is easy to shoot.

  FIG. 6F shows a display example when an enlargement instruction is given when the safety line 606 is displayed superimposed on the live view image 401, and is displayed superimposed on the safety line 606. The object is displayed so as to be enlarged. When receiving the enlargement instruction, if the center of the image is enlarged and displayed, the user must perform an operation of moving the display area to the vicinity of the safety line 606. On the other hand, in this modified example, a predetermined position including the inner and outer regions of the safety line 606 is enlarged and displayed according to the enlargement instruction. As a result, it is possible to more easily check whether the subject is within the safety line 606 (or whether an undesired subject is not included).

  As described above, in the modified example described above, the user can more easily enlarge and display subjects included or not included in the shooting range. Whether the subject is included in the shooting range more easily by enlarging and displaying whether the subject is included or not included in the shooting range so that the area inside and outside the safety line is included You can check whether or not.

  In addition, although demonstrated that the user can select the kind of grid to display, the aspect marker and safety line which were shown in the modification may also be included as an option. That is, a desired auxiliary line may be selected (auxiliary line setting) from a plurality of types of auxiliary lines for shooting including a grid, a safety line, and an aspect marker. In this case as well, the enlarged display area of the live view image differs between when the auxiliary line is displayed and when it is not displayed.

  The imaging control apparatus may be controlled by a single piece of hardware, or the entire apparatus may be controlled by a plurality of pieces of hardware sharing the processing.
