  FIG. 1 is a block diagram illustrating a configuration of a digital camera 100 that is an imaging apparatus according to an embodiment. The digital camera 100 includes a lens 1, a diaphragm 2, an image sensor 3, an analog amplification unit 4 (hereinafter referred to as A-AMP 4), an A / D conversion unit 5 (hereinafter referred to as ADC 5), and a CPU 6. , An image processing unit 7, a video encoder 8, a liquid crystal display unit 9 (hereinafter referred to as an LCD 9), an operation unit 10, a DRAM 11, a FLASH memory 12, and a bus 13.

  The lens 1 focuses the optical image of the subject on the image sensor 3. The lens 1 may be a single focus lens or a zoom lens.

  The diaphragm 2 defines the passage range of the light beam reaching the image sensor 3 based on a command from the CPU 6.

  The image pickup device 3 is an image pickup device in which a Bayer array color filter is arranged in front of a photodiode constituting each pixel. The image pickup device 3 receives the light collected by the lens 1 by a photodiode constituting a pixel and performs photoelectric conversion, and outputs the amount of light to the A-AMP 4 as a charge amount. The image pickup device 3 may be a CMOS type or a CCD type. A color image sensor other than the Bayer array may be used.

  The A-AMP 4 performs waveform shaping on the electrical signal (analog image signal) output from the image sensor 3 while reducing reset noise and the like, and further increases the gain so that the target brightness is obtained.

  The ADC 5 converts the analog image signal output from the A-AMP 4 into a digital image signal (hereinafter referred to as image data).

  The bus 13 is a transfer path for transferring various data generated in the digital camera to each unit in the digital camera. The bus 13 is connected to the ADC 5, the CPU 6, the image processing unit 7, the video encoder 8, the DRAM 11, and the FLASH memory 12.

  The image data output from the ADC 5 is temporarily stored in the DRAM 11 via the bus 13. The DRAM 11 is a storage unit that temporarily stores various data such as image data obtained by the ADC 5 and image data processed by the image processing unit 7 or the like.

  An image processing unit (also referred to as a dummy image generation unit) 7 performs various operations such as optical black subtraction processing, white balance correction processing, synchronization processing, gamma correction processing, and color reproduction processing on the image data read from the DRAM 11. Appropriate image processing. The image processing unit 7 also generates a dummy image described later.

  A CPU (also referred to as an imaging mode setting unit) 6 integrally controls each unit in the imaging apparatus 100. In particular, the CPU 6 alternately sets a still mode for acquiring a still image and a through image mode for acquiring a through image (live view image) during continuous shooting.

  The video encoder 8 reads out image data stored in the DRAM 11 or the FLASH memory 12, converts it into a video signal or the like, and outputs it to an LCD (display unit) 9. The converted video signal can also be output to an external display device such as a television.

  The operation unit 10 is an operation member such as a power button, a release button, and various input keys. When any one of the operation members of the operation unit 10 is operated by the user, the CPU 6 executes various sequences according to the user's operation. The power button is an operation member for instructing power on / off of the digital camera. When the power button is pressed, the CPU 6 turns on or off the power of the digital camera. The release button has a two-stage switch of a first release switch and a second release switch. When the release button is pressed halfway and the first release switch is turned on, the CPU 6 performs a shooting preparation sequence such as AE processing and AF processing. When the release button is fully pressed and the second release switch is turned on, the CPU 6 performs shooting by executing a shooting sequence.

  The FLASH memory 12 stores various parameters necessary for the operation of the digital camera, such as a white balance gain and a low-pass filter coefficient corresponding to the white balance mode, and a manufacturing number for specifying the digital still camera. The FLASH memory 12 also stores various programs executed by the CPU 6. The CPU 6 reads parameters necessary for various sequences from the FLASH memory 12 according to a program stored in the FLASH memory 12, and executes each process. Further, the FLASH memory 12 records still images and moving images obtained by photographing.

  The FLASH memory 12 is a memory built in the main body of the digital camera 100, but may be replaced by a memory card that can be attached to and detached from the main body of the digital camera 100.

  The digital camera 100 can set a normal shooting mode in which a single photo is taken by a single shooting operation and a continuous shooting mode in which a plurality of continuous photos are taken by a single shooting operation. The user can set the digital camera 100 to the normal shooting mode or the continuous shooting mode by operating the operation unit 10.

  FIG. 2 is a flowchart showing the processing contents when the continuous shooting mode is set, which is performed by the digital camera 100 which is the imaging apparatus according to the embodiment. The process starting from step S10 is mainly performed by the CPU 6.

  In step S10, it is determined whether or not the power button has been pressed from the power-off state. When the user presses the power button, the digital camera 100 is activated. If it is determined that the power button has been pressed, the process proceeds to step S20.

  In step S20, the digital camera 100 is set to the through image mode.

  In step S30, a through image is captured.

  In step S40, the through image captured in step S30 is displayed on the LCD 9.

  In step S50, it is determined whether or not the power button is pressed again by the user. If it is determined that the power button has been pressed again, the power of the digital camera 100 is turned off and all the processes are terminated. On the other hand, if it is determined that the power button is not pressed, the process proceeds to step S60.

  In step S60, it is determined whether or not the release button has been pressed. If it is determined that the release button has not been pressed, the process returns to step S20 to continue capturing and displaying a through image. If it is determined that the release button has been pressed, the process proceeds to step S70.

  In step S70, the digital camera 100 is set to the still mode.

  In step S80, imaging of a still image is started for continuous shooting.

  In step S90, the image processing unit 7 generates a dummy image different from the through image captured in step S30 and the still image captured in step S80.

  In the imaging device according to the embodiment, during continuous shooting, the still mode and the through image mode are alternately switched, and when the through image mode is set, the through image is displayed on the LCD 9, and when the still mode is set, the through image is acquired. Since this is not possible, a dummy image is displayed on the LCD 9.

  The dummy image is, for example, a black image in which the luminance values of all the pixels are 0. A dummy image may be generated based on at least one image captured in at least one of the still mode and the through image mode. For example, an average luminance of at least one image captured in at least one of the immediately preceding still mode and the immediately preceding through image mode is obtained, and an image based on the obtained average luminance (for example, a gray single color image) Can be a dummy image. When a dummy image is generated using a through image captured in the immediately preceding through image mode, it is preferable to use the latest image with the latest imaging time.

  Further, based on a plurality of images captured in at least one of the still mode and the through image mode, an image when it is assumed that the image was captured when the still mode was set is generated, and the generated image may be used as a dummy image. Good. For example, based on a plurality of images captured in time series with the moving body as a subject, an image in which the position of the moving body is predicted when it is assumed that the image is captured when the still mode is set is generated. A known method can be used to generate such an image.

  Furthermore, based on the average level of color signals (R signal, G signal, B signal, Cb signal, Cr signal, etc.) of an image captured in at least one of the still mode and the through image mode, a dummy An image may be generated.

  In step S100, the dummy image generated in step S90 is displayed on the LCD 9.

  In step S110, it is determined whether or not the still image has been captured. If it is determined that the still image has not been captured, the process returns to step S90, and the generation and display of the dummy image is continued. On the other hand, if it is determined that the still image has been captured, the process proceeds to step S120.

  In step S120, the still image obtained by imaging is recorded in the FLASH memory 12.

  In step S130, the digital camera 100 is set to the through image mode.

  In step S140, a through image is captured.

  In step S150, the through image captured in step S140 is displayed on the LCD 9.

  In step S160, it is determined whether or not the number of through images to be captured during the through image mode setting has reached the predetermined number. The number of through images to be captured when the through image mode is set is preset. If it is determined that the number of captured through images in the through image mode setting has not reached the planned number, the process returns to step S130, and the through image is captured and displayed again. On the other hand, if it is determined that the number of through images has reached the planned number, the process returns to step S60.

  FIG. 3 is a diagram illustrating a time chart when the continuous shooting mode is set. As described above, when the continuous shooting mode is set, the still mode and the through image mode are alternately switched. When the still mode is set, the still image is picked up and the still image obtained by the picking up is processed.

  When the through image mode is set, the through image is captured at the same rate as the moving image shooting, and the through image obtained by the imaging is processed. In the example illustrated in FIG. 3, the number of through images taken when the through image mode is set is six. The image processing of the through image may be performed in parallel with the image acquisition or may be performed after the image acquisition. In the example shown in FIG. 3, through-image processing is performed in parallel with image acquisition.

  In the example illustrated in FIG. 3, the image processing unit 7 generates a dummy image using the through image that was captured last when the through image mode was set. For example, when six through images T0 to T5 illustrated in FIG. 3 are captured when the through image mode is set, the image processing unit 7 generates a dummy image D0 using the last captured through image T5. For example, the average brightness of the through image T5 is obtained, and a gray image having the obtained average brightness is generated as a dummy image.

  When the still mode is set, dummy images generated by the image processing unit 7 are sequentially displayed on the LCD 9.

  In the example shown in FIG. 3, dummy images D0 to D7 are generated when the still mode is set after the through images T0 to T5 are captured. These dummy images D0 to D7 may all be the same image or different images. In the case where all the dummy images D0 to D7 are the same image, when the dummy image D0 is generated, the dummy image D0 is generated eight times without displaying the dummy images D1 to D7. .

  When generating all the different dummy images D0 to D7, for example, the image processing unit 7 converts a plurality of images gradually changing from a through image T5 to a gray one-color image having an average luminance of the through image T5 as a dummy image. It can be generated as D0 to D7. In this case, the dummy image D7 is a gray one-color image having the average luminance of the through image T5.

  Note that when the first still mode is set, since there is no previous through image, a dummy image using the previous through image cannot be generated. Therefore, an image prepared in advance (for example, a black-painted image in which the luminance values of all the pixels are 0) is displayed on the LCD 9 until the first through image is displayed.

  FIG. 4 is a diagram for explaining the display effect when the dummy image displayed during the still mode setting period is a filled image in which the luminance values of all the pixels are the same. Here, it is assumed that a moving body moving at a constant speed is taken continuously. 4A is a diagram showing a time change in the position of a moving body that moves at a constant speed, and FIG. 4B shows a time change in the position of the moving body when a dummy image is displayed when the still mode is set. FIG. 4 (c) is a diagram showing a change over time of the position of the moving body in the conventional technique in which the previous through image is continuously displayed when the still mode is set.

  In FIG. 4B, the solid line is a trajectory of the moving body displayed as a through image, and the dotted line is a diagram showing an example of the trajectory of the moving body predicted by the user in the brain when the still mode is set. When the moving body moves in a specific direction, even if the moving body disappears on the LCD 9, the user generally predicts the movement of the moving body in the brain based on the trajectory of the moving body so far. I do. Therefore, when the moving body is not displayed on the LCD 9 when the still mode is set, and a solid image with the same luminance value of all the pixels is displayed, the moving body is based on the locus of the moving body in the through images displayed so far. In the user's brain, the motion of the moving body is predicted. Thereby, when the still mode is switched to the through image mode, the position of the moving body in the through image does not change greatly from the position of the moving body predicted in the brain. For this reason, the user can easily capture the movement of the moving body on the LCD 9 during continuous shooting.

  On the other hand, in the conventional technique, as shown in FIG. 4C, the through image displayed immediately before is displayed as it is during the still image capturing period. Accordingly, during the still mode period, the position of the moving body on the LCD 9 does not change, and therefore, the position of the moving body displayed on the LCD 9 changes abruptly when switching to the through image mode. This makes it difficult for the user to capture the movement of the subject on the LCD 9 when switching from the still mode to the through image mode during continuous shooting.

  FIG. 5 is a diagram for explaining the display effect when the dummy image displayed in the still mode setting period is an image based on the average luminance of one image captured in the immediately preceding through image mode. FIG. 5A is a diagram illustrating a temporal change in the average luminance of the through image when the through image obtained by capturing the moving object is continuously displayed on the LCD 9, and FIG. 5B is a diagram illustrating the previous through when the still mode is set. FIG. 5C is a diagram showing a temporal change in the average luminance of the image displayed on the LCD 9 when a dummy image based on the average luminance of one image captured in the image mode is displayed. It is a figure which shows the time change of the average luminance of the image displayed on LCD9 at the time of displaying the black-colored dummy image which made the luminance value of all the pixels 0. The periods Ta, Tb, Tc in FIG. 5B and the periods Td, Te, Tf in FIG. 5C are still mode setting periods, respectively.

  When a black-painted image in which the luminance values of all the pixels are 0 is used as a dummy image, the average luminance of the image displayed on the LCD 9 is 0 when the still mode is set. Therefore, when the through image mode is switched to the still mode and when the still mode is switched to the through image mode, the luminance change of the image displayed on the LCD 9 becomes large as shown in FIG.

  On the other hand, when the image based on the average luminance of one image captured in the immediately preceding through image mode is used as a dummy image, as shown in FIG. 5B, when the through image mode is switched to the still mode. The average brightness of the image displayed on the LCD 9 does not change. Even when the still mode is switched to the through image mode, the average luminance of the image displayed on the LCD 9 does not change so much. Therefore, an image with little change in luminance can be displayed during continuous shooting, and the burden on the user's eyes can be reduced.

  FIG. 6A shows an example of transition of the display image on the LCD 9 when a black dummy image with the luminance values of all pixels being 0 is displayed on the LCD 9 during the still mode setting period during continuous shooting. FIG. FIG. 6B is a diagram illustrating an example of transition of the display image on the LCD 9 when the immediately preceding through image is frozen and displayed during the still mode setting period during continuous shooting. FIGS. 6A and 6B respectively show seven images when the moving car is continuously photographed. However, images 61 to 63 and images 66 to 67 in FIG. 6A and images 71 to 73 and images 76 to 77 in FIG. 6B are display images when the through image mode is set. Images 64 to 65 in (a) and images 74 to 75 in FIG. 6B are display images when the still mode is set.

  In the still mode setting period, when displaying a black dummy image in which the luminance values of all the pixels are 0, the user can move in the brain based on the movement trajectory of the car in the through image displayed so far. Predict the movement of a moving car. In FIG. 6 (a), in order to facilitate understanding, the trajectory of the moving vehicle is indicated by a dotted line in the images 61 to 67, and is predicted on the dummy images 64 and 65 in the user's brain. The position of the car is shown in white. However, in the actual dummy image, since the luminance value of all the pixels is 0, the car is not displayed.

  As shown in FIG. 6A, during the still mode setting period, a black dummy image with the luminance values of all the pixels being displayed is displayed to switch from the still mode to the through image mode, that is, the LCD 9 When the display image is switched from the image 65 to the image 66, the position of the car in the through image 66 is close to the position of the car predicted by the user in the brain, so the user is a moving object. Easy to catch the car.

  On the other hand, in the case of the prior art in which the previous through image is continuously displayed during the still mode setting period, the position of the vehicle in the image 74 and the image 75 displayed during the still mode setting period is as shown in FIG. The position is the same as the position of the car in the immediately preceding through image 73. In this case, when the still mode is switched to the live view mode, that is, when the display image of the LCD 9 is switched from the image 75 to the image 76, the user can predict the motion in the previous images 73, 74, and 75 by moving object prediction. From the position of the car, the position 76a in the image 76 is set as the predicted position of the car. However, since the car is moving, the position 76a predicted by the user is greatly separated from the actual position 76b. For this reason, it becomes difficult for the user to catch a vehicle that is a moving body when switching from the still mode to the through image mode.

  FIG. 7 shows a case where an image based on the average brightness of a through image taken immediately before (for example, a gray color image) is displayed on the LCD 9 as a dummy image during the still mode setting period during continuous shooting. It is a figure which shows an example of the transition of a display image. In FIG. 7, as in FIG. 6, seven images 81 to 87 are shown when the moving car is continuously photographed. However, in FIG. 7, images 81 to 83 and images 86 to 87 are display images when the through image mode is set, and images 84 to 85 are display images when the still mode is set.

  When the image based on the average brightness of the through image captured immediately before is displayed as a dummy image during the still mode setting period, the user is based on the movement trajectory of the car in the through image displayed so far, Predict the movement of a car moving in the brain. In FIG. 7, in order to facilitate understanding, the trajectory of the moving vehicle is indicated by a dotted line in the images 81 to 87, and the vehicle predicted in the user's brain is displayed on the dummy images 84 and 85. Indicates the position. However, the car is not displayed in the actual dummy image. Accordingly, when the still mode is switched to the through image mode, that is, when the display image of the LCD 9 is switched from the image 85 to the image 86, the position of the car of the through image 86 is predicted by the user in the brain. Since it is close to the position of the car, the user can easily catch the car that is a moving body.

  FIG. 8 shows a dummy created by creating an image in which the position of a vehicle, which is a moving object, is predicted based on a plurality of through images taken during the through image mode setting during the still mode setting period during continuous shooting. FIG. 6 is a diagram illustrating an example of transition of a display image on the LCD 9 when an image is displayed on the LCD 9. FIG. 8 shows seven images 91 to 97 when the moving car is continuously photographed as in FIGS. 6 and 7. However, in FIG. 8, images 91 to 93 and images 96 to 97 are display images when the through image mode is set, and images 94 to 95 are display images when the still mode is set. In addition, in order to facilitate understanding, in the images 91 to 97, the trajectory of a car that is a moving body is indicated by a dotted line.

  The image processing unit 7 generates dummy images 94 and 95 in which the position of the vehicle that is the moving body is predicted based on a plurality of through images (for example, through images 91 to 93) captured when the through image mode is set. According to the method of generating and displaying the dummy images 94 and 95 in which the position of the vehicle that is the moving body is predicted during the still mode setting period, it is displayed on the LCD 9 when the still mode is switched to the through image mode. The brightness of the image and the position of the car that is a moving body do not change significantly. That is, the user can visually recognize the image displayed on the LCD 9 without feeling uncomfortable.

  As described above, according to the imaging apparatus in one embodiment, the still mode for acquiring a still image and the through image mode for acquiring a through image at the time of continuous shooting in which a plurality of continuous photos are shot by a single shooting operation. Are alternately displayed, and when the through image mode is set, the through image is displayed on the LCD 9, and when the still mode is set, the still image and the still image based on the image captured in at least one of the still mode and the through image mode are displayed. A dummy image different from the through image is generated and displayed on the LCD 9. Thereby, even when switching from the still mode to the through image mode, at least in the user's brain, the continuity of the moving body displayed on the display unit is not lost, and the moving body can be easily captured.

  In addition, by generating a dummy image based on the average luminance of the image captured in at least one of the still mode and the through image mode, the luminance change can be achieved even when switching from the through image mode to the still mode. Fewer image displays can be realized.

  In the imaging device according to the embodiment, an image captured in at least one of the still mode and the through image mode is gradually changed to an image based on the average luminance of the image captured in one mode. A plurality of images can be generated as dummy images. According to this method, since the image displayed on the LCD 9 changes smoothly, it is possible to reduce a sense of discomfort when viewing the display image.

  In the imaging device according to the embodiment, a dummy image can be generated based on an average level of color signals of images captured in at least one of the still mode and the through image mode. According to this method, an image display with little color change can be realized.

  In the imaging device according to the embodiment, a dummy image can be generated based on the latest image among images captured in at least one of the still mode and the through image mode. According to this method, it is possible to reduce the change in the display image when switching from the through image mode to the still mode.

  In the imaging device according to the embodiment, a dummy image can be generated based on a plurality of images captured in at least one of the still mode and the through image mode. According to this method, for example, based on a plurality of through images, it is possible to generate an image when it is assumed that the image was captured during the still mode period as a dummy image. Can be displayed.

In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, you may delete some components of all the components shown by embodiment.

  As described above, the dummy image can be generated based on at least one image captured in at least one of the still mode and the through image mode. Therefore, a dummy image can be generated based on a still image captured in the still mode, or a dummy image can be generated based on both a still image captured in the still mode and a through image captured in the through image mode. You can also
