  However, the above-described conventional digital camera has to provide a plurality of types of arithmetic circuits for each application as described above in order to enable various multiplex photography. For this reason, the conventional digital camera cannot perform multiple shooting with a simple circuit configuration.

The present invention has been made to solve such problems,
A mask pattern storage means for storing a plurality of types of mask patterns for concealing a predetermined range of the imaging region;
A selection means for selecting an arbitrary mask pattern from a plurality of types of mask patterns stored in the mask pattern storage means;

  According to this configuration, using the plurality of types of mask patterns stored in the mask pattern storage unit, each shooting area is shot by the shooting unit, and each shot image is combined by the combining unit. For this reason, various photographed images can be combined according to the type of mask pattern stored in the mask pattern storage means. Therefore, a camera capable of synthesizing various captured images with a simple circuit configuration including only a mask pattern storage means without including a plurality of arithmetic circuits as in the prior art is provided.

Further, the present invention provides a boundary changing means for changing a boundary position between a photographing area of a predetermined range hidden by the mask pattern selected by the selecting means and a non-hidden photographing area adjacent thereto,
Boundary position storage means for storing the boundary position changed by the boundary change means,
The photographing means photographs a photographing area that is not hidden by the mask pattern having the boundary position changed by the boundary changing means, and a photographing area that is divided by the boundary position stored by the boundary position storage means and hidden by the mask pattern. And
The synthesizing unit synthesizes the captured images of the imaging region that is not hidden by the mask pattern captured by the imaging unit and the imaging region that is hidden by the mask pattern.

  According to this configuration, the boundary position between the imaging area in a predetermined range hidden by the mask pattern selected by the selection means and the imaging area adjacent to the predetermined area is changed by the boundary changing means. For this reason, it is possible to photograph with various mask patterns without being limited to the mask patterns previously stored in the mask pattern storage means.

  According to this configuration, when the transmittance of the imaging region hidden by the mask pattern is changed by the transmittance changing unit, the captured image of the imaging region hidden by the mask pattern remains according to the transmittance. For this reason, when the synthesized image is combined with the captured image of the same imaging area that is captured without being hidden by the mask pattern, the remaining captured image is combined with the captured image that is not hidden by the mask pattern according to the transmittance. A highly interesting multiplex image is generated.

  In addition, the present invention is characterized by comprising registration means for allowing the photographer to record an arbitrary mask pattern in the mask pattern storage means.

An enter button 6 is provided inside the cross button 5. The determination button 6 is operated when determining a desired setting item selected by operating the cross button 5.

  FIG. 2 is a block diagram showing an outline of an electric circuit configuration of the digital camera 1 shown in FIG. In the figure, the same parts as those in FIG.

  The digital camera 1 includes a CPU (Central Processing Unit) 11, a nonvolatile memory 12 composed of an EEPROM (Electrically Erasable Programmable Read Only Memory), and a buffer memory 13 composed of a RAM (Random Access Memory). Yes. The nonvolatile memory 12 stores a control program that is referred to when the CPU 11 performs various controls. In accordance with a control program stored in the nonvolatile memory 12, the CPU 11 controls each part of the circuit using the buffer memory 13 as a temporary storage work area and operates various device functions of the digital camera 1.

  Light from the subject is taken into the digital camera 1 through the lens 14 constituting the optical system. The subject light captured in the digital camera 1 projects a subject image on the imaging surface 15 a of the imaging unit 15. The imaging unit 15 includes a charge coupled device (CCD), a complementary metal oxide semiconductor (CMOS), and the like, and a subject image formed on the imaging surface 15a of the imaging unit 15 is converted into an analog imaging signal. The converted image signal is converted into a digital signal by the A / D converter 16. The image processing unit 17 acquires the imaging signal converted into a digital signal by the A / D conversion unit 16 via the bus 18 and performs image processing such as white balance processing and gamma correction on the acquired imaging signal. The image data of the photographed image is generated. The image data generated by the image processing unit 17 is compressed by the CPU 11 and stored in the buffer memory 13, and is also stored in a memory card 20 that is attached to and detached from a slot (not shown) via the I / F unit 19. To be recorded.

  The CPU 11 is connected to the release button 2, zoom button 4, cross button 5, and enter button 6 described above as an operation unit 7. When the release button 2 constituting the operation unit 7 is operated by the photographer, the subject light is exposed to the imaging unit 15 and an imaging signal of the subject image is generated. On the monitor 3 described above, a subject image captured by the imaging surface 15a of the imaging unit 15 is displayed as a through image, and the photographer confirms the composition using the through image.

  In the present embodiment, the non-volatile memory 12 constitutes a mask pattern storage unit, and stores a plurality of types of mask patterns that hide a predetermined range of an imaging region in which the imaging unit 15 captures an object. As the types of mask patterns, for example, there are mask patterns shown in FIGS. These mask patterns are displayed on the monitor 3 by the CPU 11 when the shooting mode of the digital camera 1 is set to the multiple shooting mode. The mask pattern used for photographing is determined by the photographer operating the cross button 5 to select one arbitrary mask pattern from the mask patterns displayed on the monitor 3 and operating the decision button 6. . The monitor 3, the cross button 5, the enter button 6, and the CPU 11 constitute selection means for selecting an arbitrary mask pattern from among a plurality of types of mask patterns stored in the nonvolatile memory 12.

  4A shows a left and right mask, FIG. 2B shows a left and right mask whose boundary is set to gradation, FIG. 3C shows an upper and lower mask, and FIG. 4D shows a center mask. An area A represented in white in each mask pattern indicates an area that is imaged for the first time without the imaging area being masked. On the other hand, a region B represented in black indicates a region where the photographing region is masked and hidden by the first photographing and is photographed the second time. Further, in the area C represented by the white and black gradation in FIG. 5B, the transmittance of the mask increases as the color changes from black to white, and the ratio of the captured image hidden by the mask decreases. The border area to be blurred is shown. The mask transmittance in the area C may be configured to be arbitrarily settable by the photographer on the menu screen.

  When the multiple shooting mode is set, the image processing unit 17 is captured for the first time without being hidden by the mask pattern selected by the photographer when generating the image data of the image captured by the imaging unit 15. The captured image of the area A is combined with the captured image of the area B captured for the second time. The CPU 11, the imaging unit 15, and the image processing unit 17 have imaging means for imaging each imaging area of the area A that is not hidden by the first imaging and the area B that is not hidden by the second imaging by the mask pattern selected by the selection means. It is composed. The image processing unit 17 constitutes a synthesizing unit, and synthesizes the captured images of the imaging regions A and B that are not hidden by the mask pattern captured by the imaging unit. The synthesized captured image is recorded on the memory card 20 by the CPU 11 via the I / F unit 19. The CPU 11 constitutes a recording unit that records the synthesized captured image.

  FIG. 4 is a flowchart showing an outline of the multiple moving image creation process performed by the CPU 11 of the digital camera 1.

  In S <b> 1, the CPU 11 determines whether or not the masked multiple shooting mode is set on the menu screen or the like as the shooting mode of the digital camera 1. If this determination is “No”, the multiple moving image creation process ends. On the other hand, when the multiple shooting mode with mask is set and the determination in S1 is “Yes”, the CPU 11 displays a plurality of mask patterns shown in FIG. Select the mask pattern. Subsequently, when a mask pattern is selected, the CPU 11 performs a mask pattern display 1 process for displaying a mask area corresponding to the selected mask pattern on the through image of the monitor 3 in S3. For example, when the mask pattern shown in FIG. 3A is selected, the CPU 11 displays an unmasked area A in the left half on the monitor 3 as shown in FIG. The area B to be masked on the right half is displayed. Subsequently, in S4, the CPU 11 determines whether or not the release button 2 is fully pressed and the first moving image shooting is started. When this determination is “No”, the CPU 11 repeats the determination process of S4 until the release button 2 is fully pressed. On the other hand, when the CPU 11 detects in S4 that the release button 2 has been fully pressed, in S5, the first moving image shooting is started. In this moving image shooting, a moving image in the unmasked area A in the left half is shot. Subsequently, in S6, the CPU 11 determines whether or not the release button 2 is fully pressed again and the first moving image shooting is completed. When this determination is “No”, the CPU 11 returns the process to S5 and continues the moving image shooting. On the other hand, when it is detected that the release button 2 is fully pressed and the determination in S6 is “Yes”, and the first moving image shooting is completed, the CPU 11 stores the first shooting data in the memory card 20 in S7. To do.

  Next, in step S8, the CPU 11 inverts the area B masked in the first moving image shooting and the area A not masked, and the left half on which the diagonal lines are drawn as shown in FIG. The mask pattern display 2 process for displaying the masked area A and the unmasked area B in the right half on the through image of the monitor 3 is performed. Subsequently, in S9, the CPU 11 determines whether or not the release button 2 has been fully pressed, and determines whether or not the second moving image shooting has been started. When this determination is “No”, the CPU 11 repeats the determination process of S9 until the release button 2 is fully pressed. On the other hand, when the CPU 11 detects in S9 that the release button 2 has been fully pressed, in S10, the second moving image shooting is started. In this moving image shooting, a moving image in the unmasked region B in the right half is shot. Subsequently, in S <b> 11, the CPU 11 determines whether or not the release button 2 is fully pressed again and the second moving image shooting is completed. If this determination is “No”, the CPU 11 returns the process to S10 and continues moving image shooting. On the other hand, when it is detected that the release button 2 is fully pressed and the determination in S11 is “Yes”, and the second moving image shooting is completed, the CPU 11 reads the first shooting data from the memory card 20 in S12. Then, the image processing unit 17 performs a multiple moving image creation process for synthesizing the read shooting data of the first area A and the shooting data of the second area B. When the multiple moving image creating process is completed in S12, a composite shot image of a moving image as shown in FIG. 5C is completed. The CPU 11 stores the completed composite captured image in the memory card 20 and ends the multiple moving image creation process.

  According to the digital camera 1 according to the present embodiment, as described above, each of the imaging regions A and B is illustrated using the plurality of types of mask patterns illustrated in FIG. 3 stored in the nonvolatile memory 12. 4, S5 and S10 are photographed by the photographing means, and each photographed image is synthesized by the image processing unit 17 in the processing of FIGS. For this reason, it is possible to synthesize various captured images according to the types of mask patterns stored in the nonvolatile memory 12. Therefore, a digital camera 1 that can synthesize a variety of captured images with a simple circuit configuration that includes only a non-volatile memory 12 that stores a plurality of types of mask patterns without providing a plurality of arithmetic circuits as in the prior art. Is done. In addition, it is possible to synthesize a captured image using only the digital camera 1 without using a device other than the digital camera 1, for example, a PC (personal computer). Therefore, it is possible to easily synthesize the captured image.

  In the present embodiment, the case where the multiple moving image creation process is performed in S12 after the second moving image is shot in FIG. 4 and S11 has been described. However, in S10, the multiple moving images are simultaneously recorded when the second moving image is shot. A creation process may be performed.

  Further, at the time of the second moving image shooting of S10, the shooting may be performed while the first shooting result is displayed slightly in the masked area A on the left half.

  Further, the area indicated by the oblique lines masked by the mask pattern may not be completely visible in the black image but may be seen through to some extent. In addition, only the boundary line may be displayed without displaying the masked area indicated by the oblique lines.

  Further, the first shooting data stored in S7 may be stored in the buffer memory 13 instead of the memory card 20 if the buffer memory 13 built in the camera has a sufficient storage capacity. Further, the first shooting data storage in S7 stores the shooting data in the masked area B as a black image or the entire shooting area. When all the shooting areas are stored, the second shooting data obtained in S10 is superimposed with a predetermined mask pattern in the multiple moving image creation processing in S12, and a composite image is generated.

  Next, a second embodiment in which the camera according to the present invention is applied to a digital camera will be described.

  The digital camera according to the present embodiment is different from the digital camera 1 according to the first embodiment described above in that the multiple moving image creation processing is performed by post-processing using two captured moving image data. The configuration is the same as that of the first embodiment. Therefore, the electric circuit configuration is the same as the configuration shown in FIG. 2 and will be described using the reference numerals attached to the same drawing.

  FIG. 6 is a flowchart showing an outline of the multiple moving image creation process performed by the CPU 11 of the digital camera 1 according to the second embodiment.

  In this multiple moving image creation process, the CPU 11 determines whether or not the multiple edit mode with mask is set on the menu screen of the digital camera 1 or the like in S21. If this determination is “No”, the multiple moving image creation process ends. When the multiple editing mode with mask is set and the determination in S21 is “Yes”, the CPU 11 causes the photographer to select the mask pattern by displaying the mask pattern shown in FIG. 3 on the monitor 3 in S22. Subsequently, the CPU 11 refers to the memory card 20 to display a list of a plurality of moving image data recorded on the memory card 20 on the monitor 3, and in S23, displays the first moving image data to be combined with the cross button. 5 and a decision button 6 are used to perform shooting data 1 selection processing for the editor to select. Subsequently, also in S24, as in S23, photographing data 2 selection processing for causing the editor to select the second moving image data to be combined is performed.

  Next, in S <b> 25, the CPU 11 causes the monitor 3 to display a screen for confirming whether or not to execute a multiple moving image creation process for combining the shooting data selected by the editor. If the editor does not select execution of the multiple video creation process and the determination in S25 is “No”, the multiple video creation process ends. On the other hand, when the editor selects execution of the multiple moving image creation process and the determination in S25 is “Yes”, the CPU 11 selects the first moving image data selected in S23 and S24 in S26. The image processing unit 17 is caused to execute a multiple moving image creation process for combining the second moving image data. In this process, among the first moving image data selected in S23, the data of the area A that is not hidden by the mask pattern selected in S22, and the second moving image data selected in S24, The data of the area B hidden by the mask pattern selected in S22 is synthesized. When the multiple moving image creating process is completed in S26, the CPU 11 stores the completed composite shot image in the memory card 20, and ends the multiple moving image creating process.

  Also with the digital camera 1 according to the present embodiment, the photographed images recorded on the memory card 20 can be combined using a plurality of types of mask patterns illustrated in FIG. 3 stored in the nonvolatile memory 12. This can be done in the desired manner. Therefore, the digital camera 1 according to the present embodiment can achieve the same effects as those of the first embodiment described above, and can synthesize various captured images with a simple circuit configuration including only the nonvolatile memory 12. A digital camera 1 is provided.

  In the second embodiment described above, if the length of the shooting time differs between the selected first moving image data and the second moving image data, the moving image with the shorter shooting time is used. A composite image is generated in accordance with the image data. In this case, it is possible to configure the editor to arbitrarily determine the time for starting the synthesis and the time for ending the synthesis in accordance with the short moving image data.

  Further, in each of the above embodiments, the case has been described in which the composite image is generated according to the region divided by the mask pattern illustrated in FIG. 3 stored in the nonvolatile memory 12, but the present invention is limited to this. There is no.

  For example, the cross button 5, the decision button 6, and the change button 6 for changing the boundary position between a predetermined range of the imaging region B hidden by the mask pattern selected by the selection unit and the non-hidden imaging region A adjacent to the digital camera 1. You may make it provide the boundary change means comprised by the buffer memory 13 etc. which memorize | store the boundary position changed by the boundary change means comprised by CPU11, and the boundary position. In this case, the photographing unit including the CPU 11, the imaging unit 15, and the image processing unit 17 stores the photographing region A that is not hidden by the mask pattern having the boundary position changed by the boundary changing unit, and the boundary position storage unit. The imaging region B that is divided by the boundary position and hidden by the mask pattern is imaged. The synthesizing unit configured by the image processing unit 17 synthesizes the captured images of the imaging area A that is not hidden by the mask pattern captured by the imaging unit and the imaging area B that is hidden by the mask pattern.

  In such a configuration, for example, when the selected mask pattern is displayed on the through image of the monitor 3 in S3 of FIG. 4, the photographer operates the cross button 5 to change the boundary position. The determined boundary position 6 can be determined, and the changed boundary position is stored in the buffer memory 13. The CPU 11 performs the first shooting for the area A whose boundary position has been changed in S5 in the figure, and then inverts the area to be masked based on the boundary position stored in the buffer memory 13, and in S10 in the figure, The second shooting is performed for the region B whose boundary position has been changed, and in S12 of FIG.

  According to the digital camera 1 having such a configuration, as described above, the boundary position between the imaging area B in a predetermined range hidden by the mask pattern selected by the selection unit and the imaging area A adjacent to the imaging area A is not hidden. It is changed by the boundary changing means. For this reason, photography is possible with various mask patterns without being limited to the mask patterns stored in the nonvolatile memory 12 in advance.

  Further, the digital camera 1 having the above-described configuration including the boundary changing unit may include a change timing storage unit configured by a buffer memory 13 or the like that stores the timing at which the boundary position is changed by the boundary changing unit. . In this case, the photographing means stores the boundary position of the photographing region B that was hidden by the mask pattern in the first photographing at the timing stored by the change timing storing means at the second photographing. By changing to the boundary position, the imaging region B that has been hidden by the mask pattern in the first imaging is captured.

  In such a configuration, for example, the timing when the photographer operates the cross button 5 to change the boundary position in S5 of FIG. Thereafter, in S10 of the figure, the boundary position is changed at the timing stored in the buffer memory 13, and the second photographing is performed.

  According to the digital camera 1 of this configuration, the boundary position of the imaging region B that was hidden by the mask pattern in the first imaging is the timing stored by the boundary position storage means when the second imaging is performed. The boundary position is stored in the boundary position storage means. For this reason, even when the boundary position of the shooting area is changed in moving image shooting, the change timing is read from the change timing storage means by the shooting means, so that the synthesis range is switched at an appropriate timing, and according to the photographer's request. Can create a variety of videos.

  In addition, the digital camera 1 according to each of the embodiments described above includes a transmittance changing unit configured by the cross button 5, the determination button 6, and the CPU 11 that changes the transmittance of the photographed image in the photographing region hidden by the mask pattern. It may be.

  In such a configuration, for example, when the selected mask pattern is displayed on the live view of the monitor 3 in S3 of FIG. 4, the photographer changes the transmittance by operating the cross button 5. It can be determined with the determination button 6.

  According to the digital camera 1 of this configuration, when the transmittance of the shooting area B hidden by the mask pattern is changed by the transmittance changing unit, the shot image of the shooting area B hidden by the mask pattern is changed to the changed transmittance. Remains accordingly. For this reason, when combined with the captured image of the same imaging region B that was captured a second time without being hidden by the mask pattern, the combined image causes the captured image that remains in the captured image that is not hidden by the mask pattern according to the transmittance. Since they are combined, a highly interesting multiple photographed image is generated. Note that the change timing of the transmittance is not limited to that set before photographing such as S3 in FIG. 4, and the transmittance may be changed during photographing such as S5 and S10 in FIG. .

  In addition, the digital camera 1 according to each of the above embodiments may include a registration unit configured by the CPU 11 that allows the photographer to record an arbitrary mask pattern in the mask pattern storage unit.

  In such a configuration, for example, an arbitrary mask pattern drawn by the photographer touching the monitor 3 whose screen is formed by a touch panel and recorded in the buffer memory 13 or digitally drawn by the photographer on paper or the like. An arbitrary mask pattern taken by the camera 1 and stored in the memory card 20 can be stored in the nonvolatile memory 12 by the CPU 11. In addition, a mask pattern in which the boundary position varies during photographing can be created in advance and stored in the nonvolatile memory 12.

  According to the digital camera 1 having this configuration, the mask pattern created by the photographer can be recorded in the mask pattern storage unit by the registration unit. Therefore, it is possible to provide a camera that can synthesize a photographed image that matches the photographer's intention.

  In each of the above embodiments, the case where the captured image is a moving image has been described. However, the captured image is not limited to a moving image, and may be a still image. Even in this configuration, the same effects as those of the above-described embodiments can be obtained.

  In each of the above-described embodiments, the case where the captured image captured first and the captured image captured later are combined, that is, the case where the multiple imaging is performed twice, has been described, but the present invention is limited to this. There is no. For example, a configuration may be adopted in which two or more boundary positions are provided in the mask pattern, and the multiple masking is performed three or more times by changing the masking region three or more times. Even in this configuration, the same effects as the above-described embodiments can be obtained.

  In each of the above embodiments, the case where the camera according to the present invention is applied to a digital camera has been described. However, the present invention can also be applied to a video camera, a camera mounted on a mobile phone, and the like. Even when the present invention is applied to such a camera, the same effects as those of the above-described embodiments can be obtained.
