Japanese Patent No. 4449973

  By the way, examples of evaluation items for evaluating a photograph include various items such as the position of the main subject and the facial expression of the main subject (person). Therefore, when taking a picture, the user must aim for a photo opportunity while observing a plurality of evaluation items in parallel. However, in the above prior art, even if a plurality of images are displayed in a slow manner, if there are a plurality of evaluation items, it is difficult to take a picture satisfying all the evaluation items. For this reason, there has been a problem that images with high user satisfaction cannot always be taken.

  According to the present invention, it is possible to increase the probability of recording an image with high user satisfaction.

It is a block diagram explaining the example of a structure of the imaging device by one embodiment of this invention. It is a figure explaining slow view mode. It is a flowchart explaining the flow of the process in slow view mode.

  Embodiments according to the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view illustrating a configuration of an imaging apparatus to which the present invention is applied. It should be noted that illustrations and descriptions of general devices and apparatuses of cameras other than the devices and apparatuses according to the present invention are omitted. In the imaging apparatus of the present embodiment, the lens barrel 2 is attached to the camera body 1.

  The lens barrel 2 is replaceable and includes an imaging lens 20. The imaging lens 20 includes a plurality of lens groups including a zoom lens and a focusing lens, and forms a subject image on the light receiving surface of the imaging element 10 of the camera body 1. In order to simplify FIG. 1, the imaging lens 20 is illustrated as a single lens.

  The camera body 1 includes an image sensor 10, a control unit 11, a buffer memory 12, a shutter button 13, and a liquid crystal monitor 14. In addition, a recording medium 15 such as a memory card can be attached to and detached from the camera body 1.

  The image pickup device 10 is an image sensor such as a CMOS, for example, picks up a subject image formed by the image pickup lens 20, and outputs the obtained image signal to the control unit 11.

  The control unit 11 includes a CPU and other peripheral circuits, and controls the entire camera body 1. The control unit 11 generates image data from the image signal acquired from the image sensor 10. The buffer memory 12 is used for temporarily storing image data acquired based on the image signal from the image sensor 10.

  The shutter button 13 outputs a half-press operation signal to the control unit 11 when a half-press operation is performed, and outputs a full-press operation signal to the control unit 11 when a full-press operation is performed.

  The liquid crystal monitor 14 is provided on the back surface of the imaging device 1 and displays an image captured by the image sensor 10 and various setting menus. The camera body 1 may be provided with an unillustrated EVF (electronic viewfinder).

  In the shooting mode, the control unit 11 generates frame image data for display from the image signal acquired in time series from the image sensor 10 and outputs the frame image data to the liquid crystal monitor 14. As a result, a through image is displayed on the liquid crystal monitor 14. In addition, when the shutter button 13 is fully pressed, the control unit 11 performs predetermined image processing on the image signal acquired from the image sensor 10 to generate still image data, and compresses the image signal using a predetermined method such as JPEG. Processing is performed and recording is performed on the recording medium 15. In the playback mode, the control unit 11 reads and plays back still image data recorded on the recording medium 15 and displays it on the liquid crystal monitor 14. In the present embodiment, storing means saving an image in a volatile recording medium such as a buffer memory, and recording means saving an image in a non-volatile recording medium such as a memory card.

  The camera body 1 of this embodiment has a slow view mode. The slow view mode is a mode in which a through image is displayed at a display frame rate lower than the imaging frame rate when the shutter button is pressed halfway. In other words, this is a shooting mode in which the subject is displayed on the liquid crystal monitor 14 in a slow manner. In the slow view mode, still image data can be recorded on the recording medium 15 when the shutter button is fully pressed. Hereinafter, in order to distinguish between the through image display and the slow display, displaying the frame image for display on the liquid crystal monitor 14 at the same display frame rate as the imaging frame rate is a through image display, and the display frame in the slow view mode. The slow display of an image is simply called a slow display. Further, in order to perform a through image display, a process for displaying the subject on the liquid crystal monitor 14 at a normal display frame rate (the same display frame rate as the imaging frame rate) is a through image display process, and a display frame lower than the normal display frame rate. The process of displaying the subject on the liquid crystal monitor 14 at the rate is called a slow display process.

  Here, the slow view mode will be described with reference to FIG. When the slow view mode is set by the user's operation, the control unit 11 starts an imaging process in which the imaging element 10 repeatedly captures a subject image at a predetermined imaging frame rate as illustrated in FIG. The control unit 11 sequentially stores a plurality of image data obtained by the imaging process in the buffer memory 12. The control unit 11 reproduces frame images of a plurality of image data sequentially stored in the buffer memory 12 and displays a through image on the liquid crystal monitor 14. The user waits for the shooting timing while confirming the through image.

  Here, it is assumed that the user determines that the shooting timing is approaching and presses the shutter button halfway. Then, the control unit 14 performs an AF (automatic focus adjustment) process, an AE (automatic exposure calculation) process, and an AWB (automatic white balance adjustment) process based on the image data acquired at the time of the half-press operation. After these processes, the control unit 14 performs AF lock for fixing the focus adjustment state, AE lock for fixing exposure, and AWB lock for fixing white balance.

  When the shutter button 13 is half-pressed, the control unit 11 displays the frame images of the image data sequentially stored in the buffer memory 12 on the liquid crystal monitor 14 at a display frame rate lower than the imaging frame rate (that is, Slow display).

  When the storage of image data for a predetermined time from the time when the shutter button is half-pressed is completed, the control unit 11 stops writing to the buffer memory 12 and holds the image data for the predetermined time in the buffer memory 12. . Note that the predetermined time is, for example, the time required to reach the maximum data amount that can be stored in the buffer memory 12 when image data is acquired at a predetermined imaging frame rate.

  In addition, when the slow display of the frame image of the image data for the predetermined time stored in the buffer memory 12 is completed, the control unit 11 sequentially reads the frame image of the image data for the predetermined time from the buffer memory 12 and displays it slowly. . That is, the control unit 11 repeatedly performs slow display of frame images for a predetermined time held in the buffer memory 12 (that is, repeat display).

  In this way, in the slow view mode, the subject image is displayed slowly, so that the user can appropriately aim for a photo opportunity even for a fast moving subject.

  By the way, the evaluation items for evaluating a photograph (image) include various items such as the position of the main subject and the facial expression of the main subject (person). For example, in a track and field competition, it is assumed that a photograph that a user wants to take is a moment when a runner that is a main subject finishes. When the runner tries to shoot a moment when he finishes the goal, the photographer captures the runner's facial expression at the position where the runner cuts the goal tape and the runner's facial expression is accurate. Here, the fact that the runner's facial expression is accurate includes no blinking. In addition, evaluation items with high importance include the absence of out-of-focus, blurring, overexposure and underexposure. Furthermore, the importance of these evaluation items is considered to vary depending on the user.

  In this way, if there are multiple evaluation items, even if the subject image is displayed slowly, you must aim for a photo opportunity while observing multiple evaluation items in parallel, and take a photo that satisfies all the evaluation items. Difficult to do. Accordingly, when only one still image data corresponding to the frame image displayed on the liquid crystal monitor 14 when the shutter button 13 is fully pressed is operated, for example, the moment when the runner cuts the goal tape is captured. There is a possibility that photos that do not satisfy some evaluation items, such as runners closing their eyes, will be recorded.

  Therefore, when the shutter button 13 is fully pressed, the control unit 11 according to the present embodiment reads out from the buffer memory 12 image data corresponding to a predetermined number of frame images that are displayed slowly before and after the full press operation. Specifically, image data corresponding to five frame images before and after the full-pressing operation of the shutter button 13, that is, a total of ten frame images, is read from the buffer memory 12. The five images before and after the full-press operation of the shutter button 13 are the image data corresponding to the frame image displayed at the time of the full-press operation, the four image data taken before that, and the full-press It is five image data imaged after the image data corresponding to the frame image currently displayed at the time of operation. That is, 10 pieces of image data acquired by the image sensor 10 within a predetermined period near the timing at which the image data corresponding to the frame image displayed when the shutter button 13 is fully pressed is acquired by the image sensor 10. is there. And the control part 11 performs the selection process which selects several image data based on the predetermined | prescribed selection reference | standard from ten read image data. Note that the image data read from the buffer memory 12 may be image data corresponding to a frame image that is slowly displayed within a predetermined time before and after the full-press operation. For example, the image data corresponding to the frame image slow-displayed for 1 second before the full-press operation and the image data corresponding to the frame image slow-displayed for 1 second after the full-press operation are read from the buffer memory 12. In other words, the image data corresponding to the frame image that is slow-displayed for 1 second before and after the full press operation time point, that is, for a total of 2 seconds, is read from the buffer memory 12.

  In the selection process, for example, three pieces of image data are selected from ten pieces of image data read from the buffer memory 12 based on a predetermined selection criterion. The predetermined selection criteria include, for example, no blinking, no blurring, blurring of the image, no overexposure or underexposure, and the control unit 11 detects a known blinking detection process, shake detection process, and the like. Three pieces of image data are selected based on the result.

  The control unit 11 records the three pieces of image data selected by the selection process on the recording medium 15 and displays them on the liquid crystal monitor 14. Note that the control unit 11 may display one image determined to be the best image among the three image data on the liquid crystal monitor 14 as a representative image. The control unit 11 may add the information that one image determined to be the best image is a representative image to the image data and record it on the recording medium 15.

  As described above, in the slow view mode, by performing the selection process in response to the full pressing operation of the shutter button 13, for example, an image without blinking or image blur can be recorded. Therefore, for example, when shooting a track and field event, the user can easily grasp the moment when the runner cuts the goal tape while watching the slow display of the live view image, and the camera body 1 can perform the selection process before and after the moment. It is possible to select and record an optimal runner's facial expression from the limited time, and to take a picture satisfying more evaluation items. In addition, since the user can focus on one point that he / she wants to focus on most, shooting can be simplified. It should be noted that the image data that the user considers best may be selected from the three selected image data. Further, only the image data selected by the user may be recorded.

  Here, the flow of processing executed by the control unit 11 in the above-described slow view mode will be described with reference to the flowchart shown in FIG. When the slow view mode is set by operating an operation button (not shown), the control unit 11 starts the process shown in FIG. In step S <b> 1, the control unit 11 starts an imaging process in which the imaging element 10 captures a subject image at a predetermined imaging frame rate (for example, 30 fps). Then, the control unit 11 starts a through image display process in which the frame images sequentially obtained by the imaging process are reproduced at the same display frame rate as the imaging frame rate and displayed on the liquid crystal monitor 14, and the process proceeds to step S2.

  In step S2, the control unit 11 determines whether or not the shutter button 13 has been pressed halfway. If a half-press operation signal is not input from the shutter button 13, a negative determination is made in step S2, the process returns to step S1, and the through image display process is continued. On the other hand, if a half-press operation signal is input from the shutter button 13, the control unit 11 makes a positive determination in step S2, ends the through image display process, and proceeds to step S3.

  In step S3, the control unit 11 performs AF (automatic focus adjustment) processing of the imaging lens 20, and proceeds to step S4.

  In step S4, the control unit 11 starts a process of storing image data for a predetermined time in the buffer memory 12 from the time when the shutter button 13 is half-pressed, and proceeds to step S5.

  In step S5, the control unit 11 starts a slow display process for displaying the frame image of the image data stored in the buffer memory 12 at a display frame rate lower than the imaging frame rate, and proceeds to step S6.

  In step S6, the control unit 11 determines whether or not the shutter button 13 has been fully pressed. When the full-press operation signal is not input from the shutter button 13, the control unit 11 makes a negative determination in step S6 and proceeds to step S9. On the other hand, when a full-press operation signal is input from the shutter button 13, the control unit 11 makes a positive determination in step S6 and proceeds to step S7.

  In step S <b> 7, the control unit 11 reads from the buffer memory 12 the image data corresponding to the frame image displayed on the liquid crystal monitor 14 when the shutter button 13 is fully pressed and the predetermined number of image data before and after the frame image. Then, the control unit 11 performs the above-described selection process on the read image data, and proceeds to step S8.

  In step S8, the control unit 11 records the three pieces of image data selected by the selection process in step S7 on the recording medium 15, and displays them on the liquid crystal monitor 14. And the control part 11 complete | finishes a slow display process, returns to step S1, and restarts a through image display process.

  Note that, in step S9 that proceeds with a negative determination in step S6 because the shutter button 13 is not fully pressed, the control unit 11 determines whether or not the half-press operation of the shutter button 13 is released. When the half-press operation of the shutter button 13 is released, the control unit 11 makes an affirmative determination in step S9, ends the slow display process, returns to step S1, and restarts the through image display process. On the other hand, when the half-press operation of the shutter button 13 is not released, the control unit 11 makes a negative determination in step S9, returns to step S5, and continues the slow display process.

  Further, the camera body 1 of the present embodiment is configured to execute the selection process even in the through image display mode. The through image display mode is a shooting mode in which a through image display process is always performed on the liquid crystal monitor 14. Here, a flow of processing executed by the control unit 11 in the through image display mode will be described. When the through image display mode is set by operating an operation button (not shown), the control unit 11 starts an imaging process for causing the image sensor 10 to capture a subject image at a predetermined imaging frame rate (for example, 30 fps). Then, the control unit 11 starts a through image display process in which the frame images of the image data sequentially obtained by the imaging process are reproduced at the same display frame rate as the imaging frame rate and displayed on the liquid crystal monitor 14.

  Thereafter, when a half-press operation signal is input from the shutter button 13, the control unit 11 performs AF processing of the imaging lens 20. Then, the control unit 11 temporarily stores the image data captured by the image sensor 10 in the buffer memory 12 sequentially. Unlike the slow view mode described above, in the through image display mode, the latest predetermined time of image data is temporarily stored, and overwritten and erased in order from the old frame image data.

  When a full-press operation signal is input from the shutter button 13, the control unit 11 stores image data for 10 sheets in the buffer memory 12 thereafter. Then, the control unit 11 reads out 10 pieces of image data before and after the full press operation of the shutter button 13 from the buffer memory 12, that is, a total of 20 pieces of image data, and executes the above-described selection process from the frame image data. The control unit 11 records the five images selected by the selection process on the recording medium 15 and displays them on the liquid crystal monitor 14.

  Thus, by performing the selection process even in the through image display mode, it is possible to record an image free from, for example, blinking, blurring, and image blurring. However, in the through image display mode, the 20 images to be selected in the selection process are images captured in about 0.7 seconds when the imaging frame rate is 30 fps, which is not always sufficient. Therefore, it is conceivable to increase the number of images to be selected in the selection process, but in this case, there is a high probability that the user will miss the moment that he / she really wants to shoot. Further, as the number of images to be selected increases, the load on the control unit 11 increases and the processing time for the selection process increases.

  On the other hand, in the slow view mode described above, since the subject image is displayed slowly, the user can easily grasp the shooting timing, so even if the number of images to be selected in the selection process is small, the user You can get a picture of the moment you really want to shoot. Therefore, the number of images to be selected in the selection process is set to 10 in the slow view mode, and is smaller than 20 in the through image display mode. Thereby, in the slow view mode, the load on the control unit 11 can be reduced and the processing time of the selection process can be shortened compared to the through image display mode.

  In the slow view mode, it is easy for the user to capture the shooting timing. Therefore, even when the number of images to be selected in the selection process is small, it is possible to acquire an image of the moment that the user really wants to shoot. Therefore, the number of selected sheets in the selection process is set to 3 in the slow view mode, and is smaller than 5 in the through image display mode. Thereby, in the slow view mode, the capacity of the recording medium 15 can be saved as compared with the through image display mode. Further, in the slow view mode, it is possible to make it easier for the user to select the image that the user thinks is the best from the images selected by the camera compared to the through image display mode.

According to the embodiment described above, the following operational effects can be obtained.
(1) The imaging device includes an imaging device 10 that acquires image data at a predetermined imaging frame rate, a control unit 11 that sequentially stores a plurality of image data acquired by the imaging device 10 in the buffer memory 12, and a buffer memory 12. The controller 11 displays the frame image of the image data stored on the LCD monitor 14 at a display frame rate lower than the imaging frame rate, the shutter button 13 that instructs image recording, and the shutter button 13 during the slow display. When the image sensor 10 is fully pressed, the image data corresponding to the frame image displayed on the liquid crystal monitor 14 at the operation timing is acquired by the image sensor 10 within a predetermined period near the timing when the image sensor 10 acquires the image data. Three pieces of image data based on a predetermined standard out of ten pieces of image data And a control unit 11 that selects a control section for recording the selected image data on the recording medium 15, a. Thereby, the probability of recording an image with high user satisfaction can be increased.

(2) In the imaging device of (1), the control unit 11 corresponds to the frame image displayed on the liquid crystal monitor 14 at the timing of fully pressing the shutter button 13 when operating in the slow view mode. The image data is selected from the first number (10) of image data acquired by the image sensor 10 within a predetermined period in the vicinity of the timing when the image data is acquired by the image sensor 10, and operates in the through image display mode. In this case, image data is selected from the second number (20) of image data acquired by the image sensor 10 within a predetermined period in the vicinity of the timing when the shutter button 13 is fully pressed, and the first The number of sheets (10) was configured to be smaller than the second number (20). Thereby, compared with the through image display mode, the slow view mode can reduce the load on the control unit 11 and can shorten the time required for the image data selection process.

(3) In the imaging device of (1) or (2), when the control unit 11 is operating in the slow view mode, the frame displayed on the liquid crystal monitor 14 at the timing of fully pressing the shutter button 13 Selecting a third number (three) of image data from a plurality of image data acquired by the image sensor 10 within a predetermined period in the vicinity of the timing when the image data corresponding to the image is acquired by the image sensor 10; When operating in the through image display mode, a fourth number (5) of images from among a plurality of image data acquired by the image sensor 10 within a predetermined period in the vicinity of the timing when the shutter button 13 is fully pressed. Data was selected and the third number (3) was configured to be smaller than the fourth number (5). Thereby, in the slow view mode, the capacity of the recording medium 15 can be saved as compared with the through image display mode. Further, it is possible to simplify the operation of selecting the image that the user considers best from the images selected by the camera.

(Modification 1)
In the above-described embodiment, the example in which the images displayed before and after the full pressing operation of the shutter button 13 are the images to be selected in the selection process has been described. However, only the image displayed immediately before the time when the shutter button 13 is fully pressed may be selected as an image to be selected in the selection process.

(Modification 2)
In the above-described embodiment, the example in which the number of images to be selected in the selection process is 10 in the slow view mode and 20 in the through image display mode has been described. However, the number of images to be selected in the selection process in the slow view mode and the through image display mode may be at least two. The number of images to be selected in the slow view mode and the through image display mode may be the same.

(Modification 3)
In the embodiment described above, an example has been described in which the number of selected sheets in the selection process is three in the slow view mode and five in the through image display mode. However, the selection number in the selection process in the slow view mode and the through image display mode may be at least one. The selected number of images in the slow view mode and the through image display mode may be the same.

(Modification 4)
In the embodiment described above, the image data selected in the selection process is recorded. However, the user may select the image data to be recorded. For example, the control unit 11 selects three images by the selection process and displays them on the liquid crystal monitor 14. The user selects an image to be recorded from the three images displayed on the liquid crystal monitor 14. The user may select one image or a plurality of images.

(Modification 5)
In the above-described embodiment, the example in which the image data obtained by the imaging process is sequentially stored in the buffer memory 12 when the slow view mode is set by the user's operation has been described. However, the present invention is not limited to this, and a plurality of pieces of image data obtained sequentially by the imaging process may be sequentially stored in the buffer memory 12 when the shutter button is half-pressed.

(Modification 6)
In the embodiment described above, when the shutter button is fully pressed, the recording image is recorded and the slow display process is terminated. The present invention is not limited to this, and the slow display process may be continued so that the shutter button can be fully pressed a plurality of times. Then, every time the shutter button is fully pressed, the image data to be recorded may be selected by the selection process. Alternatively, image data corresponding to the frame image displayed on the display unit 18 when the shutter button is fully pressed may be recorded on the recording medium 15 as a recording image. In this case, the slow display process may be terminated when all the image data stored in the buffer memory 12 is displayed in a slow display. In the case of repeat reproduction, an operation for terminating the slow display may be provided separately.

(Modification 7)
In the above-described embodiment, an example in which a predetermined number of images that are displayed slowly before and after the time when the shutter button 13 is fully pressed in the slow view mode is set as an image to be selected in the selection process has been described. However, the image to be selected in the selection process is not limited to the image that is displayed in a slow manner. For example, when performing slow display by thinning out the image data acquired by the image sensor 10 and stored in the buffer memory 12, the thinned (that is, not slow-displayed) image data is selected in the selection process. It may be included in the image. That is, a plurality of images captured within a predetermined period in the vicinity of the imaging timing of the image displayed when the shutter button 13 is fully pressed (both a slow-displayed image and an image that is thinned and not displayed slowly) The image to be selected in the selection process.

  The above description is merely an example, and is not limited to the configuration of the above embodiment. Moreover, you may combine the structure of each modification suitably with the said embodiment.
