  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram illustrating a main functional configuration of a digital camera as an example of an imaging apparatus according to an embodiment of the present invention.

  The taking lens 10 includes a zoom lens for continuously changing the focal length and a focus lens for adjusting the focus. These lenses are driven by the zoom control unit 44 and the distance measurement control unit 42. The taking lens 10 forms an image of a subject on the image pickup surface of the image pickup device 14. The image pickup device 14 is a photoelectric conversion image pickup device that outputs an electrical signal corresponding to the light intensity of the subject image formed on the image pickup surface, and a CCD type or MOS type individual image pickup device is used.

  The aperture 12 is operated by the exposure control unit 40. An analog video signal from the image sensor 14 is input to the A / D converter 16 and converted from an analog signal to a digital signal. The A / D converted digital signal is subjected to various image processing such as gamma correction and white balance correction by the image processing unit 20. The image display memory 24 is a memory that can store data for a plurality of frames captured by the image sensor 14. The image processed image data is temporarily stored in the image display memory 24.

  The system control unit 112 is connected to the exposure control unit 40, the camera posture detection unit 106, and the like, and performs sequence control when the camera operates. The system control unit 112 displays a power switch 72 for turning on / off the camera, a shutter switch 62 for opening and closing the shutter at a set shutter speed value in conjunction with the release, a full-press switch 64, and a display on the display unit 54. An operation unit 70 is provided for selecting various menu contents when shooting a camera. When the subject brightness is low, the flash 48 is emitted. The image display unit 28 and the display unit 54 may have the same configuration. In addition, the image display unit 28 (display unit 54) in the present embodiment has a touch panel function, and can specify the position touched by the user. The touch detection mechanism necessary for this touch panel function will be described as being provided in the image display unit 28 (display unit 54). Note that the touch panel function itself is a known technique, and detailed description thereof is omitted.

  In addition to the image data converted by the image processing unit 20, the image data stored in the image display memory 24 matches the focus information for determining the feature position of the subject's face or the focus confirmation position arranged at a fixed position. Shadow information such as information on the location and information of the camera posture detection unit 106 is also stored together. Data stored in the image display memory 24 is recorded in storage media 200 and 210 (recording units 200 and 210) such as a memory card. When recording image data in the storage media 200 and 210, data compression is generally performed in a predetermined compression format, for example, the JPEG method. The compression / decompression unit 32 performs data compression when recording image data and photographing information in the storage media 200 and 210, and decompression processing of the image data compressed from the storage media 200 and 210. The storage medium 200 is, for example, a compact flash (registered trademark), a memory card, or an SD memory card.

  The nonvolatile memory 56 is a nonvolatile memory capable of electrically erasing and recording stored data and the like, and for example, an EEPROM or the like is used. The memory 52 is a memory for storing constants, variables, programs and the like for operating the system control circuit 50. The communication unit has a communication function.

An antenna (connector in the case of wired communication) 112 connects the digital camera to other devices via a packet network, a network, and the Internet by a communication unit. The connectors 82 and 84 are connection parts that connect the power supply control unit 80 and the power supply 86. The power source 86 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 display image data written in the image display memory 24 is displayed by the image display unit 28 via the D / A conversion circuit 26. By sequentially displaying the image data on the image display unit 28, the electronic finder function can be realized. The optical viewfinder 104 can take an image using only the optical viewfinder without using the electronic viewfinder function of the image display unit 28.

  The timing generation circuit 18 is controlled by the memory control unit 22 and the system control unit 112. The memory 30 is a memory for storing captured still images and moving images. The barrier control unit 46 controls the operation of the protection unit 102. The mode dial switch 60 can switch and set various function modes such as power-off, automatic shooting mode, shooting mode, panoramic shooting mode, moving image shooting mode, playback mode, multi-screen playback / erase mode, and PC connection mode. The playback mode switch 66 is a mode switch for executing the image playback processing described in the present embodiment. The attitude mode switch 68 is a switch that automatically determines whether the camera is shooting in the vertical position or in the horizontal position.

  The storage medium 200 includes a recording unit 202 composed of a semiconductor memory, a magnetic disk, and the like, an I / F 204 that is an interface with the digital camera 100, and a connector 206 that connects to the digital camera. The storage medium 210 includes a recording unit 212 composed of a semiconductor memory, a magnetic disk, or the like, an I / F 214 that is an interface with the digital camera, and a connector 216 that connects to the digital camera. The I / Fs 90 and 94 are interfaces for connecting the storage media 200 and 210 such as a memory card and a hard disk and the system bus. The connectors 92 and 96 are connection portions that connect the storage media 200 and 210 such as a memory card and a hard disk and the I / Fs 90 and 94. The storage medium attachment / detachment detection means 98 is a sensor that detects whether or not the storage media 200 and 210 are attached to the connectors 92 and 96.

  An original image is stored in the image data area. The image data is compressed in a predetermined compression format, for example, the JPEG method, but is not limited to this. The storage device 56 stores software for compression / decompression, and performs compression of image data including shooting information captured in the RAM 52 and decompression of the compressed image data.

  Next, the processing flow of the present invention will be described with reference to FIGS.

  FIG. 3 is a flowchart for explaining focal length change processing executed by the system control unit 112 of the imaging apparatus 100 or the CPU of the imaging apparatus 100 (not shown) to represent the embodiment of the present invention.

  The flowchart in FIG. 3 is a flowchart that is started when the user tries to shoot a moving image.

  First, in step S300, the imaging apparatus 100 determines whether the lens attached to the imaging apparatus is a zoom lens. If the attached lens is not a zoom lens, the process proceeds to step S302, and if it is a zoom lens, the process proceeds to step S301. Note that in the case of an imaging apparatus in which a zoom lens is integrated, such as a compact digital camera, the process of step S300 is not performed, and the process automatically proceeds to step S301.

  When the process proceeds to step S301, the imaging apparatus 100 displays a menu screen and waits for user input. The menu screen to be displayed will be described with reference to FIG.

  FIG. 5 is a schematic diagram illustrating a menu screen image displayed on the display unit 54 of the imaging apparatus 100 according to the embodiment of the present invention.

  5 indicates various menu items displayed before shooting a moving image, and 501 indicates a selection item for selecting whether or not to perform a zoom simulation during moving image recording.

  When the column 501 in FIG. 5 is selected by the touch panel function or the operation of the operation unit 70, the screen transitions to the screen in FIG.

  FIG. 6 is a schematic diagram illustrating a menu screen image displayed on the display unit 54 of the imaging apparatus 100 according to the embodiment of the present invention.

  6 is a screen image displayed after the column 501 in FIG. 5 is selected by the touch panel function or the operation of the operation unit 70.

  In the item 601, as in 602 and 603, “Yes” or “No” can be selected for “zoom simulation during moving image recording”. When the user selects the active part by operating the touch panel function or the operation unit 70 in the state where “Yes” of “Zoom simulation during moving image recording” is activated as in 602, the zoom simulation during moving image recording is executed. When the mode is switched to and the “No” column 603 is selected, the mode shifts to a mode in which zoom simulation in moving image recording is not executed. Returning to the flowchart of FIG.

  In step S301, when the imaging apparatus 100 displays the menu screen, the imaging apparatus 100 accepts user input on the screens as shown in FIGS. 5 and 6, and proceeds to step S303.

  On the other hand, if it is determined in step S300 that the mounted lens is not a zoom lens, the process proceeds to step S302, and the menu screen for the user as shown in FIG. Displayed so that the user cannot select. Thereafter, the processing of the present invention is finished, and normal moving image shooting is started.

  When the process proceeds to step S303, the imaging apparatus 100 divides the process depending on whether the item input from the user in step S301 is “Yes” or “No” for “zoom simulation during moving image recording”. If “zoom simulation during moving image recording” is “Yes”, the process proceeds to step S304, and the moving image recording process of the present invention is started. On the other hand, when “zoom simulation during moving image recording” is “not performed”, the processing of the present invention is finished and normal moving image shooting is started.

  When the process proceeds to step S304, the imaging apparatus 100 starts the moving image recording process performed in the present invention. A screen image displayed on the display unit 54 during the moving image recording process according to the present invention will be described with reference to FIG.

  FIG. 7 is a schematic diagram illustrating a screen image displayed when recording a moving image on the display unit 54 of the imaging apparatus 100 according to the embodiment of the present invention.

  Reference numeral 700 in FIG. 7 denotes a screen image and an operation panel displayed at the time of moving image recording, and reference numeral 701 denotes a software button for instructing the start of zoom simulation during moving image recording. Note that this button may be a software button on the touch panel or a hardware button attached to the imaging apparatus main body. Returning to the flowchart of FIG.

  In the following step S305 and subsequent steps, processing when the 701 button in FIG. 7 is pressed during moving image recording will be described. In step S305, when the button 701 for instructing the start of zoom simulation is pressed, the imaging apparatus 100 proceeds to the next step S306.

  In step S306, the imaging apparatus 100 displays a setting screen for zoom simulation during moving image recording, and accepts user input. A screen image to be displayed will be described with reference to FIG.

  FIG. 8 is a schematic diagram illustrating a setting screen image of zoom simulation during moving image recording displayed on the display unit 54 of the imaging apparatus 100 according to the embodiment of the present invention.

  800 in FIG. 8 displays a setting screen for zoom simulation during moving image recording, and 804 is an image of a captured image taken at the current focal length. Thereafter, the zoom simulation setting is changed by a user operation such as the focal length adjustment bar 801 and the zoom speed adjustment bar 802. Returning to the flowchart of FIG.

  In step S306, after the zoom simulation setting screen during moving image recording is displayed, if an operation instruction is accepted by the user's touch panel operation or the operation unit 70, the process proceeds to step S307 and subsequent steps.

  In step S307, the imaging apparatus 100 determines whether the focal length after zooming has been changed from the zoom simulation setting screen of FIG. An example in which the focal length is changed will be described with reference to FIG.

  In 800 of FIG. 8, for example, when an image with a focal length of 18 mm is initially captured (moving image recording), the REC view screen 804 displays an 18 mm image. At that time, the slide position of the focal length adjustment bar 801 is the position 809.

  In the situation of 800 in FIG. 8 described above, when zooming is desired during moving image recording, the user gives an instruction to change the slide position of the focal length adjustment bar by operating the touch panel function or the operation unit 70 (not shown). Returning to the flowchart of FIG.

  In step S307, if the user operation is a focal length change instruction, the process proceeds to step S308, and if the user operation is not a focal length change instruction, the process proceeds to step S400.

  A process flow when the process is shifted to step S308 will be described.

  In step S308, the imaging apparatus 100 acquires the value of the focal length adjustment bar (in the example of FIG. 8, a value of 801, for example, a position of 808) input by the user in step S307.

  Next, in step S309, the imaging apparatus 100 displays a review screen (pseudo zoom) such as 805 in FIG. 8 on the display unit 54, and displays it as a digital zoom image with the focal length change value acquired in step S308. With this display, the entire captured image (pseudo zoom image) after zooming in can be reproduced without changing the optical zoom, and the zoom in size (focal length) can be set without adjusting it while shooting a movie. You can change the zoomed-in size without error.

  The change value of the focal length may be adjusted with a focal length adjustment bar as shown in FIG. 8, or may be designated with another digital zoom function.

  The example of FIG. 8 describes an image of zooming in with digital zoom (increasing the focal length). Conversely, an image of zooming out with digital zoom (decreasing the focal length) is described with reference to FIG. To do.

  FIG. 9 is a schematic diagram illustrating a setting screen image of zoom simulation during moving image recording displayed on the display unit 54 of the imaging apparatus 100 according to the embodiment of the present invention.

  900 in FIG. 9 displays a setting screen for zoom simulation during moving image recording, and 904 is an image of a captured image taken at the current focal length. In the case of 900, the zoomed-in state is 120 mm as in 908 of the focal length adjustment bar 901, and the image is 904. 900 is an example when the user wants to zoom out the focal length to 18 mm. When the user changes the focal length to 18 mm as in 909 using the focal length adjustment bar 901, the range corresponding to the review screen 805 in FIG. 8 is a range that cannot be captured by the optical zoom as in the review screen 905 in FIG. The image is displayed in a black frame (virtual region), and an image of the currently captured range is displayed in the whole image displayed when zoomed out. With this display, the entire captured image when zoomed out can be imaged without changing the optical zoom, and it can be set even when zooming out without adjusting the zoom out size during movie recording. The zoom out size can be changed without mistake. Returning to the flowchart of FIG.

  The description of the flowchart of FIG. 3 is completed as described above, and the process proceeds to the flowchart of FIG.

  FIG. 4 is a flowchart illustrating a focal length change process executed by the system control unit 112 of the imaging apparatus 100 or the CPU of the imaging apparatus 100 (not shown) to represent the embodiment of the present invention.

  The flowchart of FIG. 4 is a flowchart executed following the flowchart of FIG.

  First, in step S400, the imaging apparatus 100 determines whether the zoom speed has been changed from the zoom simulation setting screen of FIG. An example in which the zoom speed is changed will be described with reference to FIG.

  The user adjusts (changes) the zoom speed adjustment bar 802 in the zoom simulation setting screen 800 during moving image recording in FIG. 8 to adjust (change) the focal speed change speed (zoom speed) for zooming in. Returning to the flowchart of FIG.

  In step S400 in FIG. 4, it is determined whether the zoom speed adjustment bar 810 in FIG. 8 has been changed. If the zoom speed adjustment bar has been changed, the process proceeds to step S401, where the zoom speed adjustment bar is displayed. If not changed, the process proceeds to step S402.

  When the process transitions to step S401, the imaging apparatus 100 acquires the value of the zoom speed adjustment bar 810 on 800 in FIG.

  On the other hand, when the process transitions to step S402, the imaging device 100 proceeds to the next process. In step S <b> 402, the imaging apparatus 100 determines whether to start a simulation from a user operation on the zoom simulation setting screen of FIG. 8. With reference to FIG. 8, an example of determining whether to start the simulation will be described.

  When the user presses the play button 803 on the zoom simulation setting screen 800 during video recording in FIG. 8, the imaging apparatus 100 determines that there is an instruction to start the simulation, and shifts the processing to step S <b> 403. . On the other hand, if it is determined that the play button 803 has not been pressed, the process proceeds to step S404.

  When the process transitions to step S403, the imaging apparatus 100 reproduces an image when the optical zoom is actually performed on the display unit 54 with a digital zoom with reference to the focal length and the zoom speed acquired in step S308 and step S401. . An example of reproduction will be described with reference to FIG.

  FIG. 10 is a schematic diagram illustrating an example of zoom simulation and moving image recording displayed on the display unit 54 of the imaging apparatus 100 according to the embodiment of the present invention.

  10 in FIG. 10 is a screen image displayed on the display unit 54 after executing a simulation for zooming in to 120 mm in the situation of 800 in FIG. The zoom simulation initially zooms in by digital zooming from the focal length of 18 mm in 700 in FIG. 7 to 120 mm in 1000 in FIG. However, this zoom simulation zooms in in a pseudo manner, and moving image recording records the entire optical zoom range. Thereafter, in step S405, zoom-in is performed by actual optical zoom, and a clear and smooth zoom-in moving image is shot. Returning to the flowchart of FIG.

  Next, when the process proceeds to step S404, the imaging apparatus 100 determines whether or not the pressing of the “Yes” button 806 for executing the focal length change is accepted from the zoom simulation setting screen of FIG. With reference to FIG. 8, an example of whether or not to execute the focal length changing process will be described.

  In the setting screen for zoom simulation during moving image recording 800 in FIG. 8, the user operates the focal length adjustment bar to display an image of the current optical zoom focal length 804 and a digital zoom to change the optical zoom from now on. If 805 is different, 800 “Yes” button 806 and “No” button 807 are displayed actively. If the “Yes” button 806 for changing the focal length is pressed here, the process proceeds to step S405. Returning to the flowchart of FIG.

  When the process proceeds to step S405, the imaging apparatus 100 performs a process of changing the optical zoom to the focal length acquired in step S308 at the zoom speed set in step S401. An example in which the focal length set in step S308 is changed by optical zoom will be described with reference to FIG.

  8 in FIG. 8 is displayed on the display unit 54 after the focal length is changed by the optical zoom from the initial focal length of 700 mm in FIG. 7 to 120 mm in FIG. This is a screen image. At this time, unlike step S403, the moving image recording records the image to be optically zoomed as it is.

  This optical zoom recording has an effect that the zoom speed can be kept constant and can smoothly shift to a focal length set in advance by simulation, and the zooming process while shooting a moving image can be recorded smoothly.

  On the other hand, if the “Yes” button 806 for changing the focal length displayed in 800 of FIG. 8 is not pressed in step S404, the process proceeds to step S406. In step S406, the imaging apparatus 100 is 800. It is determined whether or not a “No” button 807 for changing the displayed focal length is pressed. If the “No” button 807 is pressed, the process returns to step S305 to return to the display screen 700 in FIG. If neither the “Yes” button 806 nor the “No” button 807 for changing the focal length is pressed, the process returns to Step S306 to return to the display of the zoom simulation setting screen during moving image recording in FIG. .
