Description

  The present invention relates to an imaging apparatus having a panoramic shooting function, a display method thereof, and a program thereof.

In a digital camera which is an example of an imaging apparatus, there is a camera equipped with a panorama shooting function in addition to a normal shooting function as a shooting function.
FIG. 10 is a diagram conceptually showing normal shooting by the normal shooting function and panoramic shooting by the panorama shooting function in such a digital camera. As shown in the figure, in normal shooting, when the user presses the shutter button (release button) once, shooting is performed once, and one image 101 is obtained. On the other hand, in panoramic shooting, when the user presses the shutter button once, the first shooting is performed, and when the panning operation is performed, the second and subsequent shootings are automatically performed a plurality of times. Then, the images (images 102 to 105 in the example in the figure) obtained by the respective photographings are connected to create one panoramic image 106. According to such a panorama shooting function, the user does not need to be aware of the shutter timing of the second and subsequent shooting, and can easily perform panorama shooting. In addition, some panoramic shooting functions can manually perform shutter timings for the second and subsequent shootings with the shutter button, and manually perform shutter timings for the second and subsequent shootings. Alternatively, some can be set automatically.

By the way, Patent Document 1 relates to overlap technology for joining images, based on movement information at the time of shooting by a digital camera measured by various sensors such as a three-dimensional gyro, A method has been proposed in which a moving distance is calculated and a panoramic image is created by extracting adjacent subject frames.

FIG. 1 is a diagram showing a system configuration of a digital camera which is an imaging apparatus according to an embodiment of the present invention.
In FIG. 1, a photographing lens 1 forms a subject image on an image sensor 2. The image pickup device 2 is an image sensor such as a CCD (Charge Coupled Device) or a CMOS (Complementary Metal Oxide Semiconductor). The image pickup device 2 photoelectrically converts an object image formed by the action of the photographing lens 1 to generate an analog electric signal. Output. The imaging unit 3 includes a CDS (Correlated Double Sampling) unit that reduces noise components, an AGC (Automatic Gain Control) unit that stabilizes signal levels, and the like. Reduces and stabilizes the signal level for output. The A / D unit 4 converts the analog electrical signal output from the imaging unit 3 into a digital electrical signal, and outputs the digital electrical signal as image data.

  The image buffer memory 5 is a memory such as a DRAM (Dynamic Random Access Memory), for example, for temporarily storing image data output from the A / D unit 4 or image data being processed by the image processing unit 13. used. For example, image data for still images, image data for through images (live images), and the like are temporarily stored. The through image refers to an image when the subject image formed on the image sensor 2 is displayed on the display unit 15 in real time.

  The display processing unit 6 performs processing for generating an image signal that can be displayed by the display unit 15 based on the image data and outputting the image signal to the display unit 15. The display unit 15 is, for example, an LCD (Liquid Crystal Display) or the like, and displays an image corresponding to the image signal output from the display processing unit 6 on the display screen.

  The built-in memory 7 is a memory built in the digital camera in advance, and records image data and the like.

  The compression / decompression unit 11 performs compression processing and decompression processing of image data by, for example, the JPEG (Joint Photographic Experts Group) method when recording image data or displaying recorded image data.

  The image processing unit 12 synthesizes (connects) image data for a plurality of still images with different shooting times to generate image data for one panoramic image, or for two through images with different shooting times. A process of detecting a motion vector from the image data is performed. In addition, various image processing is performed on the image data, such as correction processing such as gamma correction and white balance correction, and image enlargement / reduction processing (resizing processing) for increasing or decreasing the number of pixels constituting the image.

  The CPU 13 controls the operation of the entire digital camera by reading and executing the camera program stored in the Flash ROM 16. The display control unit 13a controls the display of the display unit 15 during panorama shooting, which will be described in detail later, and is realized by the CPU 13 performing display control by executing a camera program. The flash ROM 16 is a non-volatile memory that can be electrically rewritten, and stores various data used during the execution of the camera program in addition to the camera program executed by the CPU 17.

  The operation unit 17 includes various buttons for receiving various instructions from the user and notifying the CPU 13 of them. For example, a shutter button (release button), a menu button, up / down / left / right buttons, an OK button, and the like described later are included. The shutter button is a button for instructing shooting. The microphone (recording unit) 18 converts sound into sound data that is digital data, and is used for sound recording.

  Next, the panorama shooting operation will be described in detail as one of the operations of the digital camera having such a configuration. However, in this embodiment, the panorama shooting operation will be described as an example in which panorama shooting is performed by panning the digital camera from the left side to the right side after the user presses the shutter button.

First, an overview of the panorama shooting operation will be described.
In the digital camera according to the present embodiment, when the panorama shooting operation is started, the panning operation by the user is guided to the display screen of the display unit 15 so that the panning operation by the user is performed at an appropriate speed and in an appropriate direction. By displaying the zone as an index and the movement trajectory representing the status of the panning operation actually performed by the user, the user performs the panning operation so that the movement trajectory follows the guidance by the zone on the display screen, It is possible to obtain a panoramic image without subject blur.

FIG. 2 is a diagram illustrating an example of a screen displayed on the display unit 15 during the panoramic shooting operation. FIG. 3 is a diagram schematically showing an example of a series of screens displayed on the display unit 15 during the panorama shooting operation.
As shown in FIG. 2, during the panoramic shooting operation, the zone 21 and the movement locus 22 are displayed on the display screen together with the through image.

  The zone 21 includes three types of partial zones: a recommended speed zone 21a, a trajectory correction encouragement zone 21b, and a warning comment display zone 21c. The recommended speed zone 21a is a partial zone indicating that the panning operation by the user is appropriately performed when the current movement locus (black circle in the figure) 22a is included in the recommended speed zone 21a. . The trajectory correction encouragement zone 21b is a partial zone indicating that the trajectory correction is encouraged for the panning operation by the user when the current movement trajectory 22a is included in the trajectory correction encouragement zone 21b. The warning comment display zone 21c is a partial zone indicating that the panning operation by the user is too fast when the current movement locus 22a is included in the warning comment display zone 21c. In this case, FIG. As shown in one of the screen examples, a warning is displayed on the display screen.

  These three types of partial zones are changed and displayed as time passes when the panorama shooting operation is started. In the case of this example, since it is assumed that the panning operation is performed from the left side to the right side, the recommended speed zone 21a is constant according to the movement allowable speed v as time passes, as shown in FIG. The trajectory correction encouragement zone 21b and the warning comment display zone 21c are changed and displayed accordingly. In FIG. 3, the trajectory correction encouragement zone 21b and the warning comment display zone 21c are not shown.

Here, the movement allowable speed v is given by the following equation.
Allowable movement speed v = β / (1 / α) [pixel / sec]
β is an allowable value [pixel] of subject blur on the CCD, assuming that the image sensor 2 is a CCD. 1 / α is a predetermined shutter speed [sec]. As will be described in detail later, in the digital camera according to the present embodiment, when shooting a still image during panoramic shooting operation, shooting is always performed at a shutter speed faster than 1 / α. Yes. Therefore, when the panning operation by the user is equal to or less than the movement allowable speed v, it is possible to capture a still image without subject blur.

  Further, as shown in FIG. 3, the recommended speed zone 21a is displayed at the left end on the zone 21 each time the still image shooting during the panorama shooting operation is completed, and is displayed so as to move to the right again. Is done.

  Still image shooting during the panoramic shooting operation (however, the second and subsequent still image shootings) is performed when the current movement locus 22a is positioned at the right end of the display screen. That is, when the amount of movement of the movement locus 22 after the still image is captured reaches one display screen that is the length of the zone 21 in the horizontal direction (left-right direction), the next still image is captured. Therefore, when the recommended speed zone 21a is positioned at the right end on the zone 21, the movement locus 22a is positioned at the right end on the zone 21 at the same time as a suitable shooting timing for still images during the panorama shooting operation. Therefore, at least when the recommended speed zone 21a is positioned at the right end on the zone 21 and the user performs a panning operation so that the movement locus 22a is positioned at the right end on the zone 21, a still image free from subject blurring is taken. Can do.

The width in the vertical direction (vertical direction) of the zone 21 indicates a vertical movement allowable width that is allowed when a plurality of captured still images are connected (combined) to create a panoramic image.
With the display as described above, during the panning operation, the user can recognize that the current panning operation is appropriately performed when the current movement locus 22a is included in the recommended speed zone 21a. it can. In addition, when the current movement locus 22a is included in the locus correction encouragement zone 21b, it is recognized that it is preferable to correct the panning operation locus so that the movement locus 22a is included in the recommended speed zone 21a. it can. Further, when the current movement locus 33a is included in the warning comment display zone 21c or outside the sone 21, the current movement locus 22a is recommended by recognizing that the current panning operation is improperly performed. The panning operation can be modified so as to be included in the speed zone 21a. Therefore, the user can perform a panning operation during panoramic shooting at an appropriate speed and in an appropriate direction.

  In addition, when the recommended speed zone 21a is located at the right end on the zone 21, the movement locus 22a is located at the right end on the zone 21 at the same time, which is a suitable shooting timing for still images during the panorama shooting operation. The user can obtain a panoramic image without subject blur by performing a panning operation so that at least the recommended speed zone 21a is positioned at the right end on the zone 21 so that the movement locus 22a is positioned at the right end on the zone 21. it can. Therefore, it is not necessary for the user to perform the panning operation so that the current movement locus 22a is always included in the recommended speed zone 21a, which improves usability.

FIG. 4 is a diagram showing a flowchart of the panorama shooting operation including the above operation.
In the figure, when the normal shooting mode is set as the shooting mode, when the shooting mode is changed from the normal shooting mode to the panoramic shooting mode by the user operating the menu button, the up / down / left / right buttons, and the OK button, The panorama shooting mode setting is detected (S1), and the ISO sensitivity is set to the maximum value (MAX) (S2). Here, the ISO sensitivity set to the maximum value remains set to the maximum value until the shooting mode is changed from the panorama shooting mode to another shooting mode.

  When a shooting mode such as a normal shooting mode or a panoramic shooting mode is set, basically, a through image state in which a through image is continuously displayed on the display unit 15 is set.

Subsequently, it is determined whether or not the user has pressed the shutter button (S3). Here, when the determination result is NO, this determination is repeated.
On the other hand, if the determination result in S3 is YES, a still image is taken under the ISO sensitivity set to the maximum value (S4), and the display screen of the display unit 15 is initialized (S5). In the initialization of the display screen, the zone and the movement locus described with reference to FIGS. 2 and 3 are initialized and displayed together with the through image. That is, the recommended speed zone is displayed at the leftmost position on the zone, and accordingly, the orbit correction recommended zone and the warning comment display zone are displayed on the zone. In addition, as a current movement locus, a black circle is plotted and displayed at the center position of the width in the vertical direction of the zone at the left end of the zone. However, in the second and subsequent processing of S5 after the determination of S3 is YES, the black circle plotted and displayed as the movement trajectory is moved to the left end side of the zone without changing the vertical position. Are displayed, and other movement trajectories are deleted.

Further, in the process of S5, the cumulative value S of the movement amount of the horizontal component extracted from the motion vector, which is a determination target in the process of S14 described later, is cleared to 0 (S = 0).
Subsequently, the image data for the through image is captured (S6), and the captured image data for the through image is stored in the image buffer memory 5 (S7). However, when the image data set as the image data for the first through image is not stored in the image buffer memory 5, the captured image data for the through image is used as the image data for the first through image. Set as and save. Alternatively, the image data set as the image data for the first through image is stored in the image buffer memory 5, and the image data set as the image data for the second through image is stored in the image buffer memory 5. If the image data is not stored in the image data, the captured image data for the through image is set and stored as image data for the second through image.

  Subsequently, the two image data set as the image data for the first and second through images are represented in the through image related to the image data set as the image data for the first through image. A motion vector representing the amount of movement of the subject position represented in the through image related to the image data set in the image data for the second through image with respect to the subject position is detected (S8). However, if the image data set as the image data for the second through image has not been saved, the process returns to S6 without performing this process (S8) and subsequent S9. Accordingly, in this case, the image data for the through image captured in the next S6 is set and stored as the image data for the second through image.

FIG. 5 is a diagram conceptually showing the process of S8, and FIG. 6 is a diagram schematically showing the process of S8.
As shown in FIGS. 5 and 6, for example, the image data i (1) for the through image is set as the image data for the first through image, stored in the image buffer memory 5, and the image for the through image is stored. When the data i (4) is set as the image data for the second through image and stored in the image buffer memory 5, the motion vector is the image data i set as the image data for the first through image. This is obtained by detecting a difference between (1) and image data i (4) set as image data for the second through image. As a result, the image data set as the second through-image image data with respect to the subject position represented in the through-image related to the image data set as the first through-image image data. The amount of movement of the subject position shown in the through image can be obtained. In addition, although mentioned later in detail, based on the movement amount calculated | required in this way, a movement locus | trajectory is displayed on the display screen of the display part 10. FIG.

  When the process of S8 in FIG. 4 is completed, it is subsequently determined from the motion vector detected in S8 whether or not it has been detected that the digital camera has been moved in the horizontal direction (S9). In this detection, the amount of movement in the horizontal direction is extracted from the motion vector, and when the amount of movement is a predetermined amount or more, it is detected that the digital camera has been moved in the horizontal direction.

  If the determination result is NO in S9, the setting is canceled in the image data set as the image data for the second through image, and the process returns to S6. Accordingly, in this case, the image data for the through image captured in the next S6 is set and stored as the image data for the second through image.

  On the other hand, if the determination result in S9 is YES, the amount of movement in the horizontal and vertical directions is extracted from the motion vector detected in S8, and the equivalent amount of the amount of movement is displayed on the display unit 15 as the current movement locus. Display (S10) In S10, the image data set as the image data for the first through image is canceled and set as the image data for the second through image. The image data is set as the image data for the first through image, and the setting is canceled in the image data set as the image data for the second through image.

FIGS. 7A, 7B and 7C are diagrams conceptually showing a partial process of S10.
As shown in FIG. 6A, for example, the through image related to the image data set as the image data for the first through image is set as the Z th through image, and the image for the second through image is used. The through image related to the image data set as data is the Z + α th through image, and the horizontal and vertical movements extracted from the motion vectors obtained between the two through image data The amounts are defined as Δx and Δy shown in FIG. In this case, as shown in FIG. 6C, the equivalent amount of the horizontal movement amount Δx and the equivalent amount of the vertical movement amount Δy are displayed on the display unit 15 with a black circle 31 as the current movement locus. Display a plot. However, when the black circle 31 is plotted and displayed as the current movement trajectory, the equivalent of the horizontal movement amount Δx and the vertical movement amount Δy from the black circle 32 plotted as the previous movement locus. The plot is displayed at the moved position.

  In FIG. 6C, the black circles other than the black circle 31 plotted and displayed as the movement locus are black circles that have been similarly plotted and displayed as the movement locus in the past in the process of S10, and the black circle 33 is the same as that of S3. It is a black circle plotted as a movement locus when the process of S5 is performed for the first time after the determination is YES.

  In addition, in FIG. 8C, for the convenience of explanation, the interval between the black circles and the black circles plotted as the movement trajectory is shown to be large. As described with reference to FIG. 2 and FIG. 3, the black circles plotted as the movement trajectory are displayed as lines as a whole.

In FIG. 5C, in the zone 21, the recommended speed zone, the recommended trajectory correction zone, and the warning comment display zone are not shown.
When the process of S10 in FIG. 4 is completed, it is subsequently determined whether or not the movement trajectory displayed in S10 (the black circle plotted and displayed as the current movement trajectory) is present in the zone (S11). Note that this determination also determines whether or not the panning operation by the user is at a level allowed for image synthesis when creating a panoramic image. If the determination result in S11 is NO, a warning is displayed (S12), and the process proceeds to S14.

  On the other hand, if the determination result in S11 is YES, it is determined whether or not the movement trajectory displayed in S10 (black circle plotted and displayed as the current movement trajectory) exists in the warning comment display zone (S13). This determination also determines whether or not the panning operation by the user is at a level that causes subject blurring. If the determination result in S13 is YES, a warning is displayed (S12), and the process proceeds to S14. In the warning display in this case, as shown in one of the above-described screen examples in FIG. 3, a message such as “Please move a little slowly” is displayed on the display screen of the display unit 15.

  On the other hand, when the determination result in S13 is NO, or after the processing in S12, the movement amount Δx of the horizontal component extracted from the motion vector detected in S8 is added to the accumulated value S (S ← S + Δx), it is determined whether or not the accumulated value S is a predetermined amount X or more (S ≧ X) (S14). The predetermined amount X is an amount corresponding to one display screen which is the horizontal length of the zone, and this determination also determines whether or not it is the next still image capturing timing.

FIG. 8 is a diagram for conceptually explaining the processing of S14.
As shown in the figure, by repeating this process (S14), the horizontal component movement amount Δx extracted from the motion vector detected in S8 is accumulated in the accumulated value S each time. When the accumulated value S is equal to or greater than a predetermined amount X (S = Δx ₁ + Δx ₂ + Δx ₃ +... Δx _n ≧ X), the next still image shooting timing is reached, and the determination in S14 is YES.

  In this way, when the determination at S14 is made and the determination result is YES, as the shutter speed for shooting the next still image, the determination is first made at S4 after the determination at S3 becomes YES. A shutter speed (shutter speed) that matches the exposure of the captured still image is determined (S15), and the process returns to S4. In the determination of the shutter speed in S15, since the ISO sensitivity is set to the maximum value in S2, a higher shutter speed can be determined. Accordingly, in the still image capturing performed in the next S4, the still image is captured under the high shutter speed determined in S15, so that it is possible to capture a still image free from subject blurring. However, in the processing of S15, a shutter speed faster than the above 1 / α is always determined, and a shutter speed slower than that is not determined.

  On the other hand, if the determination result in S14 is No, it is subsequently determined whether or not a panorama shooting end instruction has been detected (S16). The panorama shooting end instruction can be given by, for example, pressing a shutter button. In this case, it is possible to give instructions for starting and ending panoramic photography only with the shutter button.

  When the determination result in S16 is YES, the panoramic image is obtained by joining (combining) the still image data captured in S4 so far (from the determination of S3 to YES until the current time). (S17), the image data of the panoramic image is recorded in the external memory 8 (or the internal memory 7) (S18), and the process returns to S3.

  On the other hand, if the determination result in S16 is NO, it is subsequently determined whether or not a fixed time has elapsed since the determination in S3 was YES (S19). If the determination result in S19 is YES, the process proceeds to S17, performs the processes in S17 and S18 described above, and returns to S3. On the other hand, if the determination result in S19 is NO, the process returns to S6. In this case, the image data for the through image captured in the next S6 is set and stored as the image data for the second through image.

  As described above, according to the digital camera of the present embodiment, the user can perform a panning operation during panoramic shooting at an appropriate speed and in an appropriate direction, so that a panoramic image without subject blur can be obtained.

  In the panning operation, the user does not necessarily have to perform the panning operation so that the current movement locus is always included in the recommended speed zone. At least when the recommended speed zone is positioned at the right end on the zone, Since the panning operation may be performed so that the movement locus is positioned at the right end on the zone, the usability can be improved.

  In the digital camera according to the present embodiment, the example in which the user pans the digital camera from the left side to the right side has been described, but the same processing is performed when the panning operation is performed from the right side to the left side. Needless to say, you can.

  Further, in the digital camera according to the present embodiment, when the recommended speed zone is located at the right end on the zone, the current movement locus is also located at the right end on the zone. When the recommended speed zone is located at the right end on the zone, it should be configured so that the recommended speed zone is located at the right end on the zone by voice, vibration, display, etc. Is also possible.

  Further, in the digital camera according to the present embodiment, when shooting a still image after the second time during the panorama shooting operation, the fact that the shot image of the still image has been performed is notified by voice, vibration, display, or the like. It is also possible to configure.

  In the digital camera according to the present embodiment, the second and subsequent still images are automatically shot during the panorama shooting operation. However, the digital camera according to the present embodiment may be configured to be manually performed by the user.

  Further, in the digital camera according to the present embodiment, during the panorama shooting operation, the movement trajectory for one still image from the previous still image shooting to the next still image shooting can be displayed. For example, it is possible to continuously display the movement trajectory for a plurality of still images.

FIG. 9 is a diagram schematically showing an example of a display screen when configured in such a manner.
The example shown in the figure is an example in which a moving trajectory for five still images can be continuously displayed. In this example, lines 42 (42a, 42b, 42c, 42d, and 42e) indicating the positions of the shutter timings of five captured images are displayed on the zone 41. Therefore, when the current movement locus 43 reaches the position of the line 42 (including the extension of the line 42) on the zone 41, the still image is captured at the timing for capturing the still image. When the current movement locus 43 reaches the position of the right end of the display screen (the line 42e on the zone 41 (including the extension of the line 42e)) and the still image is shot, the same as in the above-described embodiment. In addition, the zone 41 and the movement track 43 are initialized.
