  FIG. 19 is a third diagram for explaining extraction of a person from an image in this embodiment. Referring to FIG. 19, the person area is recognized in image A.

  Returning to FIG. 3, in step S123, the CPU 110 extracts an image of the person recognized in step S121 from the image A.

  In step S <b> 124, the CPU 110 stores the extracted person image in the memory 120. Thereafter, the CPU 110 returns the process to be executed to step S120 of the composite photograph process of FIG. 2 that is the caller of this person extraction process.

  Referring again to FIG. 2, after step S <b> 120, in step S <b> 131, the CPU 110 controls the liquid crystal finder 142 to display the person image extracted and stored in the memory 120. This person image is developed in the composition subject image development area 123 in the photographic image editing work area of the memory 120.

  FIG. 7 is a diagram showing a screen for confirming an image of a person extracted in this embodiment. Referring to FIG. 7, the user sees this screen and confirms the extracted person.

  FIG. 8 is a diagram showing an example of adjustment of an image of a person extracted in this embodiment. Referring to FIG. 8, at this stage, the person image can be enlarged or reduced, or the position of the person in the image can be moved.

  Returning to FIG. 2, in step S <b> 132, CPU 110 determines whether or not a person's foot is included in the extracted person image. Specifically, the CPU 110 determines whether or not the contour of the extracted person image is interrupted in the middle, in other words, whether the contour line of the extracted person image intersects the edge of the image before extraction. Judge whether or not.

  FIG. 9 is a diagram showing a case in which feet are included in the image of a person extracted in this embodiment. Referring to FIG. 9, in the case of such a person image, the outline of the person image is not interrupted, and the outline of the person image intersects with the edge of the image before extraction. It is judged that the foot is included.

  Returning to FIG. 2, if it is determined that the foot is included (YES in step S132), in step S133, the CPU 110 displays on the liquid crystal finder 142 that the image of the person includes the foot of the person. Control. For example, the liquid crystal finder 142 displays a message such as “Because the foot is included, please be careful when compositing with the background”. In addition, you may alert | report by audio | voice with or instead of a display.

  When it is determined that the foot is not included (when NO is determined in step S132), and after step S133, in step S134, the CPU 110 accepts the image of the person from the user or performs the composite photo process. It is determined which instruction to cancel is input from the user. If it is determined that an instruction to cancel is input, the CPU 110 returns the process to be executed to the process of the caller of the composite photo process.

  On the other hand, if CPU 110 determines that an instruction to approve a person image has been input, CPU 110 determines in step S135 whether an instruction to add a person has been input by the user. If it is determined that an instruction to add a person has been input (YES in step S135), CPU 110 returns the process to be executed to step S112 to obtain the above-described person image of the person to be added. Execute the process.

  On the other hand, when it is determined that an instruction not to add a person has been input (NO in step S135), in step S141, the CPU 110 performs control to display on the liquid crystal finder 142 a prompt to shoot a background. To do. For example, a message such as “Please take a background image” is displayed on the liquid crystal finder 142. In addition, you may alert | report by audio | voice with or instead of a display.

  Next, in step S142, the CPU 110 controls the liquid crystal finder 142 to display the photographed background when the user points the digital camera 100 toward the background to be photographed. This background image is developed in the composition background image development area 124 of the photographic image editing work area 121 of the memory 120 shown in FIG.

  Next, in step S143, the CPU 110 calculates the difference between the pitch angle and roll angle of the current digital camera 100 that is capturing the background image with respect to the pitch angle and roll angle of the digital camera 100 when the person image is captured. Then, the liquid crystal finder 142 is controlled to display.

  Although not shown, the pitch angle and the roll angle are detected by a gyro sensor provided in the digital camera 100. In addition, the pitch angle and roll angle of the digital camera 100 when a person image is captured are stored in the memory 120 in association with the person image.

  If the difference between the pitch angle and roll angle is greater than or equal to a predetermined value (or greater than a predetermined value), the person image and the background image may be unnaturally combined, so a warning is displayed on the liquid crystal finder 142. Control may be performed.

  In step S150, the CPU 110 executes a human background superimposing process that is a process of superimposing the human image and the background image.

  Referring again to FIG. 3, in the person background superimposing process, first, in step S <b> 151, CPU 110 reads a person image from memory 120 and develops it in the composition subject image development area of photographic image editing work area 121 of memory 120. To do.
