<1. Embodiment>
<Outline of configuration>
FIG. 1 is an external perspective view showing an example of a rear configuration of an imaging apparatus 1 according to an embodiment of the present invention.

  As shown in FIG. 1, the imaging apparatus 1 includes a finder 101, an operation button group 103, and a display unit 104 on the back surface thereof, and a shutter button (release SW) 102 on the top surface thereof.

  The display unit 104 is configured by, for example, a liquid crystal display member (LCD), has a predetermined number (here, 320 × 240) of display pixels, and can display a color image. In the display unit 104, live view image display, recorded image reproduction display, setting menu display, and the like are performed.

  In the live view image display, a plurality of relatively low resolution (here, 320 × 240) images that are continuously acquired by the image sensor 201 described later are sequentially displayed in a moving image manner. Thus, the user can perceive the position and size of the subject in the captured image and perform the framing operation by using the live view image display on the display unit 104. The time interval (update interval) at which the live view image is updated is equal to the time interval (acquisition interval) at which images are continuously acquired from the image sensor 201.

  The operation button group 103 includes a button 103a for setting the operating environment of the image pickup apparatus 1, a cross key 103b used for a zooming operation, a button 103c for turning on / off a camera shake display warning function according to the present invention, and the like.

  The shutter button 102 is a two-stage push-in switch that can be detected by distinguishing between a half-pressed state (hereinafter also referred to as S1 state) and a fully-pressed state (hereinafter also referred to as S2 state) by a user operation.

  Next, the internal configuration of the imaging apparatus 1 will be described with reference to FIG. FIG. 2 is a block diagram illustrating the internal functions of the imaging apparatus 1.

  The subject image is acquired by the image sensor 201 through a lens optical system (not shown). The image sensor 201 has a function of converting light into an electrical signal using a photoelectric effect, and is configured by, for example, a CCD or a CMOS.

  An image signal (analog signal) obtained by the image sensor 201 is subjected to analog signal processing such as level adjustment and noise removal in an analog signal processing circuit 202.

  The image signal that has passed through the analog signal processing circuit is converted into a digital signal by the A / D converter, and is temporarily stored in the image memory 215 in the RAM 214 as image data. Here, the RAM 214 is a semiconductor memory (for example, DRAM) that can be accessed at high speed. Further, the image processing unit 211 performs white balance processing, γ correction processing, color correction processing, and the like on the image data stored in the image memory 215. Thereafter, the processed image data is written to the external recording medium 207 at a predetermined timing.

  The overall control unit 210 includes an arithmetic processing unit (CPU) 212, a ROM 213, and a RAM 214. The CPU executes a predetermined control program stored in the ROM 213 to control the entire imaging apparatus 1 as a whole. In addition to various image processing functions, the overall control unit 210 has a function for extracting the contour of the main subject, a display control function for adding camera shake display, and the like.

  The operation unit 204 includes buttons, switches, and the like that can be operated by the user. The operation unit 204 is used to change the operation mode of the shutter button (release SW) 102 for the user to instruct shooting timing and the imaging apparatus 1. Mode switch and so on.

  Furthermore, the imaging apparatus 1 is provided with an external interface (external I / F) 206 for connecting an external device such as a so-called personal computer (PC) or a printer, and for example, an image obtained by photographing is transmitted to the external device. Direct output is possible.

<Operation>
Next, a photographing operation using the imaging device 1 according to this embodiment will be described.

  FIG. 3 is a flowchart showing camera shake display processing.

  When the subject is displayed in live view (step S301), when the shutter button 102 is half-pressed (S1) (step S302), automatic exposure control, auto white balance control (AWB), and hill climbing method (video) Automatic focusing control) (also referred to as a method or a contrast method) is executed (steps S303 and S304).

  Further, in this state, when a camera shake display function (step S305) described later is turned on, camera shake display control (step S306) is performed.

  When the shutter button 102 is fully pressed (step S307), the actual photographing operation is executed (step S308), and the image data is saved (step S309).

  Further, the process from step S301 to step S307 is repeated until it is fully pressed.

  As a result, the user can select an optimal framing time without camera shake while viewing the live view display.

  Next, camera shake display control (step S306) will be described in detail with reference to FIGS.

  FIG. 4 shows a detailed flowchart of camera shake display control. FIG. 5 shows images continuously acquired from the image sensor 201 at every acquisition interval (time interval Δt) from when the shutter button 102 is half-pressed to when the shutter button 102 is fully pressed. Time-series display. FIG. 5 shows images acquired at each acquisition time point T (i−3) to T (i + 2). Further, the processes from step S301 to step S307 are sequentially performed on images acquired at each time point at the time of acquisition of each image.

  Hereinafter, as an example of the camera shake display control, the camera shake display control when the image PT1 acquired at the time T (i) in FIG. 5 is displayed on the display unit 104 as the display target image will be described in detail. As will be described later, in this camera shake display control, the image PT2 acquired at time T (i-1) is adopted as a reference image, and a part of the contour in the image PT2 is added to the image PT1 as a camera shake display. .

  Specifically, first, contour extraction of an image acquired by the image sensor 201 is performed (step S401). For example, as shown in FIG. 5, it is assumed that an image PT1 in which the subject is a person is acquired from the image sensor 201 at time T (i) (FIG. 6). In this case, when the contour of the subject of the image PT1 in FIG. 6 is extracted, the result is as shown in FIG. The contour extraction can be performed by, for example, an edge detection circuit using a known digital arithmetic circuit.

  Next, the main subject in the live view image is recognized by searching for the contour adjacent to the skin color region FP and the contour connected to the skin color region FP from among the plurality of extracted contours (step) S402).

  Specifically, first, a skin color region FP adjacent to the extracted contour is detected (FIG. 8). This skin color area FP is detected as an area composed of skin color pixels adjacent to the extracted contour and skin color pixels that are successively present with respect to the skin color pixels. FIG. 8 shows a state in which a human face portion is detected as a skin color region FP adjacent to the contour RF.

  Then, a contour connected to the skin color region FP is detected, and a composite region of the region surrounded by the contour connected to the skin color region FP and the skin color region FP is defined as a main subject region (also simply referred to as a main subject). Recognize (FIG. 9). In FIG. 9, a region HP (region corresponding to a person's head) surrounded by a contour RH connected to the skin color region FP and a region BP (region corresponding to the skin color region FP) surrounded by a contour RB ( A state is shown in which a composite region PS1 of a region corresponding to a human torso) and a skin color region FP of a face portion is recognized as a main subject region.

  When a plurality of skin color regions are detected, for example, the skin color region (maximum skin color region) having the largest area among the detected plurality of skin color regions and the outline connected to the maximum skin color region are enclosed. A composite area with the area may be recognized as the main subject.

  Further, a centroid point PG1 of the extracted skin color area FP is calculated, and the centroid point PG1 is set as the representative point PG1 of the main subject (step S403).

  Here, as described above, since the process from step S301 to step S307 is executed at each time point for the image acquired at each time point, the process of the image PT2 acquired at the time point T (i−1) is performed. The representative point PG2 (specifically, the centroid point PG2 of the skin color region FP of the main subject in the image PT2) is already calculated and held at the time point T (i).

  Therefore, when camera shake display control is performed on the image acquired at time T (i), the representative point PG1 of the image PT1 at time T (i) and the representative point PG2 of the image PT2 at time T (i-1). Can be compared, and the amount of displacement of the representative points PG1, PG2 (in other words, the movement distance of the main subject) can be detected as the amount of camera shake (step S404). Note that the representative point PG1 and the representative point PG2 correspond to the same point in the actual subject, and when there is no camera shake, the positions of the representative points PG1 and PG2 are the same. Further, here, when the amount of deviation (ie, the amount of camera shake) between the representative points PG1 and PG2 is equal to or less than the set value, it is determined that there is no camera shake. The set value (threshold value) that serves as a reference for the presence or absence of camera shake may always be a constant value (fixed value), or may be changed by the user.

  Next, when it is determined that there is camera shake (step S405), the process proceeds to the camera shake display adding step (step S406), and when it is determined that there is no camera shake, the process proceeds to step S307.

  Hereinafter, the camera shake display adding step (step S406) executed when it is detected that there is camera shake (step S405) will be described with reference to FIG.

  FIG. 10 is a diagram showing simultaneously the main subject outline PR1 of the image PT1 and the main subject outline PR2 of the image PT2. FIG. 10 also shows the representative point PG1 of the main subject of the image PT1 and the representative point PG2 of the main subject of the image PT2. The positions of the representative points PG1 and PG2 are essentially the same, but are shifted due to camera shake. Here, a portion B1 (see FIG. 11) that does not overlap the main subject of the image PT1 is selected from the contour PR2 of the image PT2, and a composite image in which the selected portion is added to the image PT1 as a camera shake display in the image PT1 is displayed. This will be described in detail.

  First, the moving direction AR from the representative point PG2 to the representative point PG1 is obtained. Next, a half line LN starting from the representative point PG2 is extended in the direction opposite to the obtained movement direction AR, and an intersection point Q1 between the extended half line LN and the contour PR2 of the main subject in the image PT2 is obtained. Then, a part of the contour including the intersection point Q1 is selected from the contour PR2 in the image PT2, and the selected portion B1 is added to the newly acquired image, that is, the image PT1, and is displayed on the display unit as a live view image. It is displayed (FIG. 11). Here, as a part of the contour including the intersection point Q1, for example, a portion having a certain length centered on the intersection point Q1 may be selected.

  As described above, when a camera shake is detected, a part of the outline of the image acquired immediately before is selected from the live view image, and the selected part is additionally displayed. Overlap with the contour to be additionally displayed can be suppressed. Here, in order to suppress the overlap between the contour and the main subject, only a part of the contour is additionally displayed. However, the present invention is not limited to this, and the entire contour may be additionally displayed. .

  Further, the series of camera shake display control described above is executed at every acquisition interval (Δt) of a plurality of images. That is, in the above example, the case where the image acquired at the time T (i) is set as the display target image has been described in detail, but the same camera shake display control is executed also when another image is set as the display target image. Is done. In other words, the camera shake display control is sequentially executed while the display target image and the reference image are updated as time passes. For example, after camera shake display control using the image at time T (i) as the display target image is performed, the image acquired at time T (i + 1) (see FIG. 5) is used as the display target image and Camera shake display control using the image acquired at T (i) as a reference image is executed. Similarly, camera shake display control is performed after that, with the image acquired at time T (i + 2) as the display target image and the image acquired at time T (i + 1) as the reference image.

<2. Modification>
Although the embodiments of the present invention have been described above, the present invention is not limited to the contents described above.

  For example, in the above embodiment, the main subject in the image (reference image) acquired immediately before the display target image is displayed at each time interval (hereinafter also referred to as update interval) at which the live view image is updated. Since the camera shake display control for extracting the contour and adding the contour to the display target image is executed, the display time (afterimage display time) of each camera shake display is equal to the update interval. However, the present invention is not limited to this. Specifically, the time interval for maintaining the display of the once added contour (hereinafter also referred to as the maintenance interval) is set to a value larger than the update interval, and the additional display portion is updated at each maintenance interval. May be. According to this, it is possible to maintain the contour once added and displayed for a relatively long time (that is, to increase the afterimage display time).

  Here, it is assumed that the maintenance interval is set to 10 times the update interval. In this case, assuming that the live view image is updated at 30 frames per second, the additionally displayed contour is maintained in the live view image for 1/30 × 10 = 1/3 s, that is, 333 ms. .

  Specifically, in the case where an image acquired at a certain time T (i) is to be displayed, an outline of the image (reference image) acquired at the immediately previous time T (i-1) is additionally displayed. A composite image B1 (see FIG. 11) is generated and displayed. Thereafter, when each image acquired at each time point from the time point T (i + 1) to the time point T (i + 9) is used as a display target image, the time point T (i−1) is updated without updating the outline of the addition target. Then, the contour in the image (reference image) acquired in step (3) is continuously adopted as the contour to be added, and a composite image of the contour and the display target image acquired at each time point is generated and displayed. Therefore, since the same additional display portion B1 is continuously displayed over a time of 333 ms, an afterimage effect can be obtained.

  Thereafter, when the image acquired at time T (i + 10) is to be displayed, the outline of the addition target is updated again, and the contour in the image (reference image) acquired at time T (i + 9) immediately before that is updated. A composite image with the added is generated and displayed. Thereafter, in the case where each image acquired at each time point from time T (i + 11) to time point T (i + 19) is a display target image, the image (reference image) acquired at time point T (i + 9) The contour is continuously adopted as the contour of the addition target, and a composite image of the contour and the display target image acquired at each time point is generated and displayed. Thereafter, the same operation is repeated. According to this, an afterimage effect can be obtained.

  In the above embodiment, the case where only one image immediately before the display target image is used as the reference image is illustrated. However, the present invention is not limited to this, and a plurality of ( For example, three images may be used as reference images. For example, in the case where an image acquired at a certain time T (i) is to be displayed, the contour of the image (reference image) acquired at the immediately previous time T (i-1) and the preceding image A composite image is generated and displayed with the contours in the images (reference images) acquired at time points T (i-2) and T (i-3) as additional display portions. Thereafter, when an image acquired at time T (i + 1) is to be displayed, the contour in the image (reference image) acquired at time T (i) immediately before that and the previous time T A composite image is generated and displayed with the outline in the image (reference image) acquired in (i-1) and T (i-2) as an additional display portion. Thereafter, the same operation is repeated.

  According to this, since a plurality of contours are additionally displayed on the live view image and each contour is displayed over a period longer than the update period, a display effect can be obtained in which the subject moves with a tail. Can do.

  In this case, the maximum number of contours to be additionally displayed is three. However, the maximum number of contours to be additionally displayed in the live view image can be set by the user to limit the number of display. You can also. Considering the above example, when the maximum number is set to 2, the oldest contour may be deleted when the third contour is additionally displayed.

  In addition, when a plurality of contours are displayed based on a plurality of reference images in this way, the density of each contour that has already been additionally displayed is updated from the first additional display time of each contour at each update interval. It is also possible to change the display according to the time. Considering the above example, as shown in FIG. 12, at the time of the first additional display, the density of the contour is set to the maximum gradation value Pmax, and after the update interval (Δt) is changed to 2/3 · Pmax. Further, after the next update interval has elapsed (2 · Δt), it is changed to 1/3 · Pmax, and after the maintenance interval has elapsed, the contour is deleted. More specifically, the maximum gradation value is determined in advance for each color component (red (R) component, green (G) component, and blue (B) component), and the gray level is shaded at the above ratio with respect to the maximum gradation value. What is necessary is just to determine a value. For example, when a purple outline is added, the maximum gradation value of the R component and the B component is set to 255 and the maximum gradation value of the G component is set to 0 (zero), and each color component is set according to the elapsed time. The gray value may be changed by changing the ratio with respect to each maximum gradation value.

  FIG. 14 is a diagram illustrating the trajectory of the main subject due to camera shake. FIG. 14 shows a situation in which the main subject changes from position (initial position) PS 141 to position PS 142 and then further to position PS 143 as time passes.

  FIG. 15 shows the contours added to the live view image when the main subject changes as shown in FIG. In FIG. 15, when an image acquired at a certain time T (i) is to be displayed, a contour B152 in an image (reference image) acquired at the immediately previous time T (i−1), and A state is shown in which the outline B151 in the image (reference image) acquired at the previous time T (i-2) is displayed as the additional display portion. The outline B151 indicating the initial position PS141 indicates that the gradation value is displayed lower than the outline B152 indicating the next position PS142. According to this, it is possible to recognize the moving direction or the like of the main subject from the difference in the contour density.

  Alternatively, it is also possible to display the color of each contour that has been additionally displayed at each update interval by changing the color according to the elapsed time from the first additional display time of each contour. Considering the above example, as shown in FIG. 13, the outline color is set to red at the time of initial additional display, and the outline color is changed to green after the update interval (Δt) has elapsed. Further, after the next update interval has elapsed (2 · Δt has elapsed since the first addition), the color of the contour is changed to blue, and after the maintenance interval has elapsed, the contour is deleted. According to this, the moving direction and the like of the main subject can be recognized from the difference in the color of the contour.

  Further, in the above-described embodiment and each modification, the starting point of the change in the appearance of each contour that is additionally displayed is the first additional display time for each contour. However, the image display update interval and the image acquisition interval Since (Δt) is equal, the point in time when the image obtained by extracting the additionally displayed contour (that is, the point in time when the extraction source image corresponding to each contour is acquired) can be considered as the starting point. For example, it is expressed that the density of each contour additionally displayed on a certain display target image is changed according to the elapsed time from the acquisition time of the extraction source image corresponding to each contour to the acquisition time of the display target image. be able to. The same applies to the change of the color of each contour.

  Further, the contour determining operation in the above-described camera shake display adding step (step S406) is not limited to this.

  For example, it can be modified into the following modes (see FIG. 16).

  First, the moving direction AR from the representative point PG2 to the representative point PG1 is obtained. Next, a half line LN starting from the representative point PG2 is extended in the opposite direction of the moving direction AR. Further, as shown in FIG. 16, a half line OR obtained by rotating the extended half line LN by an angle α counterclockwise is obtained. Similarly, a half line OS obtained by rotating the half line LN clockwise by an angle α is obtained. Then, a portion B2 existing in a region between the two half lines OR and OS in the contour PR2 of the main subject may be an additional display contour (FIG. 17).

  Alternatively, it can be modified to the following mode (see FIG. 18).

  As shown in FIG. 18, the image PT2 is radially divided into eight equal parts with the representative point PG2 as the center. An area including the moved representative point PG1 is specified, and an area that is point-symmetric about the specified area and the representative point PG2 is obtained. Of the outline PR2 of the main subject, a portion B3 existing in the obtained point-symmetric area (shaded area in FIG. 18) may be used as an additional display outline (FIG. 19).

  In the above embodiment, when the movement distance of the representative point is equal to or less than the set value, it is determined that there is no camera shake and the camera shake display adding process is not performed. However, the present invention is not limited to this. For example, when it is determined that there is no camera shake, the entire outline of the main subject may be additionally displayed.
