  The CPU 11 executes various processes according to a program recorded in the ROM 12 or a program loaded from the storage unit 20 to the RAM 13.

  The RAM 13 appropriately stores data necessary for the CPU 11 to execute various processes.

  The CPU 11, ROM 12, and RAM 13 are connected to each other via a bus 14. An input / output interface 15 is also connected to the bus 14. Connected to the input / output interface 15 are a sensor unit 16, an imaging unit 17, an input unit 18, an output unit 19, a storage unit 20, a communication unit 21, and a drive 22.

  The sensor unit 16 is configured to be able to detect the posture of the imaging device 1 based on an angle with the direction of gravity using an acceleration sensor. By detecting the posture of the imaging device 1 at the time of shooting, the shooting direction indicating the positional relationship between the subject and the imaging unit 17 at the time of shooting can be grasped.

  Although not shown, the imaging unit 17 includes an optical lens unit and an image sensor.

The optical lens unit is configured by a lens that collects light, for example, a focus lens or a zoom lens, in order to photograph a subject.
The focus lens is a lens that forms a subject image on the light receiving surface of the image sensor. The zoom lens is a lens that freely changes the focal length within a certain range.
The optical lens unit is also provided with a peripheral circuit for adjusting setting parameters such as focus, exposure, and white balance as necessary.

The image sensor includes a photoelectric conversion element, AFE (Analog Front End), and the like.
The photoelectric conversion element is composed of, for example, a CMOS (Complementary Metal Oxide Semiconductor) type photoelectric conversion element or the like. A subject image is incident on the photoelectric conversion element from the optical lens unit. Therefore, the photoelectric conversion element photoelectrically converts (captures) the subject image, accumulates the image signal for a predetermined time, and sequentially supplies the accumulated image signal as an analog signal to the AFE.
The AFE performs various signal processing such as A / D (Analog / Digital) conversion processing on the analog image signal. A digital signal is generated by various signal processing and output as an output signal of the imaging unit 17.
Such an output signal of the imaging unit 17 is hereinafter referred to as “captured image data”. Data of the captured image is appropriately supplied to the CPU 11 or an image processing unit (not shown).

  A removable medium 31 composed of a magnetic disk, an optical disk, a magneto-optical disk, a semiconductor memory, or the like is appropriately attached to the drive 22. The program read from the removable medium 31 by the drive 22 is installed in the storage unit 20 as necessary. The removable medium 31 can also store various data such as image data stored in the storage unit 20 in the same manner as the storage unit 20.

  In the imaging apparatus 1 configured as described above, the acquired captured image is corrected so as to make the face that is the shape of the subject look narrow according to the shooting direction of the human face (hereinafter referred to as “thin face correction”). It has a function to change the strength.

FIG. 2 is a schematic diagram for explaining the fine face correction in the present embodiment.
As shown in FIG. 2, when a human face is photographed from above, the distance between the head portion (hair portion or the like) and the imaging device 1 is close, and the distance between the imaging device 1 and the jaw is small. For reasons such as being far away, the head becomes larger and the chin becomes thinner.
On the other hand, when the face is photographed from below, the head portion becomes smaller because the distance between the head portion and the imaging device 1 becomes longer and the distance between the imaging device 1 and the jaw becomes shorter. , The jaws appear thick.
For this reason, in the case of fine face correction, if the image is taken from above and the chin appears to be thin, the balance of the face is lost when the image deformation process is performed. The image deformation process is performed with a weaker intensity.
On the other hand, when the image is taken from below and the chin appears thick, the image deformation process is performed with an intensity stronger than the standard.
As a result, it is possible to perform correction that looks like a narrow face without breaking the balance of the face.

Here, the method of fine face correction in the present embodiment will be described.
FIG. 3 is a schematic diagram for explaining a fine face correction method according to this embodiment.

  In the fine face correction of the present embodiment, first, in an image (hereinafter referred to as “original image”) P1 to be corrected, a surrounding area (hereinafter referred to as “trimming area”) R1 including the jaw is the original image. Trim from. In the present embodiment, the trimming region R1 is a region including the jaw centered on the lower part of the nose. Specifically, the trimming region R1 is, for example, a position that is 25% shifted from the center of the face frame R0 in the jaw direction (a portion under the nose) and is 1.65 times the size of the face frame R0.

  Next, in the fine face correction, fine face correction is performed on the image P2 generated as a result of the trimming (hereinafter referred to as “trimmed image”) with an intensity corresponding to the above-described shooting direction. In the present embodiment, the fine face correction performs an image deformation process that pulls radially toward the center (in the present embodiment, an ellipse from the center) toward the center (the lower part of the nose) of the trimmed image P2. Configure as follows. In this way, by performing image deformation processing that pulls radially toward the lower part of the nose (in this embodiment, from the center to an ellipse) in the center direction, the chin is narrowed without breaking the balance of the face. Corrections can be made. By performing fine face correction on the trimmed image P2, a processed image P3 is generated.

  Thereafter, in the fine face correction, the processed image P3, which is the trimmed image P2 subjected to the image processing, is pasted to the region R2 corresponding to the trimming region of the original image P1 and synthesized, and then the image subjected to the fine face correction (hereinafter, referred to as the face image correction) This is referred to as “fine face corrected image”.) P4 is generated.

FIG. 4 is a functional block diagram showing a functional configuration for executing the fine face photographing process among the functional configurations of the imaging apparatus 1 as described above.
The small face photographing process refers to a series of processes from the original image being subjected to the fine face correction with the intensity according to the photographing direction to generate the fine face corrected image.

  When executing the narrow face photographing process, as shown in FIG. 4, in the CPU 11, the angle information acquisition unit 51, the imaging control unit 52, the face detection unit 53, the image deformation processing unit 54, and the trimming processing unit. 55 and the fine face correction image generation unit 56 function.

  An angle information storage unit 71 and an image storage unit 72 are set in one area of the storage unit 20.

  The angle information storage unit 71 stores angle information from sensor values including the sensing time at the sensor unit 16 acquired from the sensor unit 16. “Angle information” is information indicating the attitude of the imaging apparatus 1, and information on the operating state of the imaging apparatus 1 at the attitude is added together with the attitude of the imaging apparatus 1. Therefore, from the “angle information”, the posture of the imaging device 1 at the time of shooting, that is, the shooting direction (vertical / front direction) of the imaging device 1 at the time of shooting is known.

  The image storage unit 72 stores the captured image acquired from the imaging unit 17 and the generated fine face correction image data.

The angle information acquisition unit 51 acquires angle information based on the sensor value from the sensor unit 16. The angle information acquisition unit 51 stores the acquired angle information in the angle information storage unit 71.
Further, the angle information acquisition unit 51 acquires angle information at the time of capturing the original image from the angle information storage unit 71. In the present embodiment, the angle information acquisition unit 51 acquires angle information of sensing time at the sensor unit 16 corresponding to the shooting time of the original image as angle information at the time of imaging.

  The imaging control unit 52 controls the imaging unit 17 to execute the imaging process. As a result of the imaging process, a captured image is output from the imaging unit 17.

  The face detection unit 53 acquires and analyzes an original image that is a captured image output from the imaging unit 17 to detect a face. The face detection uses existing face detection technology.

  The image deformation processing unit 54 determines the strength of the image deformation processing according to the angle of the imaging device 1 at the time of shooting acquired by the angle information acquisition unit 51. Specifically, as shown in FIG. 2, the trimming processing unit 55 shoots a face from above when the angle of the imaging device 1 at the time of shooting is downward, Since the fine face effect is easily exhibited, the strength of the image deformation processing is eliminated or reduced, and when the angle of the imaging device 1 at the time of shooting is from the front, the strength of the image deformation processing is set as a standard, and at the time of shooting When the angle of the image pickup apparatus 1 is upward, the face is photographed from below. Therefore, the face to be photographed has the effect of making the entire face appear thicker as opposed to photographing in the upward direction. Since it becomes easy, the intensity | strength of an image deformation process is made stronger than a standard.

In addition, the image deformation processing unit 54 performs image deformation processing with a set intensity on a region near the jaw of the face in the trimmed image. Specifically, as shown in FIG. 3, the image transformation processing unit 54 uses the set distortion correction strengths (upward direction [none / weak], front side [standard], downward direction [strong]), and the trimmed image. Image deformation processing is performed such that the image is pulled in the radial direction (in the present embodiment, elliptical from the center) toward the center of P2 (the part below the nose).
As a result of the image transformation process, an image in which the fine face correction is performed on the trimmed image is generated.

  The trimming processing unit 55 sets the vicinity of the face jaw in the original image as a trimming region. Specifically, as shown in FIG. 3, the trimming processing unit 55 sets a peripheral region including the jaw centering on the lower part of the nose as the trimming region R1 in the original image P1. Specifically, for example, the trimming region R1 is set to a size 1.65 times as large as the face frame R0 at a position 25% shifted from the center of the face frame R0 in the jaw direction (a portion below the nose).

In addition, the trimming processing unit 55 executes a trimming process for trimming a set trimming area in the original image. Specifically, as shown in FIG. 3, the trimming processing unit 55 trims the set trimming region R1 from the original image P1.
A trimmed image composed of the trimmed area of the original image is generated.

The fine face corrected image generation unit 56 pastes the processed image to an area corresponding to the trimming area of the original image to generate a fine face corrected image. Specifically, as shown in FIG. 3, the fine face correction image generation unit 56 pastes the processed image P3 on the area R2 corresponding to the trimming area of the original image P1, thereby synthesizing the fine face correction image P4. Generate.
Further, the fine face correction image generation unit 56 stores the fine face correction image in the image storage unit 72.

FIG. 5 is a flowchart for explaining the flow of the narrow face photographing process executed by the imaging apparatus 1 of FIG. 1 having the functional configuration of FIG.
The small face photographing process is started by an operation of starting the thin face photographing process on the input unit 18 by the user. As the small face photographing process starts, the angle information acquisition unit 51 sequentially acquires the sensor values from the sensor unit 16 as angle information and stores them in the angle information storage unit 71.

If there is a face, YES is determined in step S13, and the process proceeds to step S14.
If there is no face, it is determined as NO in step S13, and the narrow face photographing process ends. At the end of the fine face photographing process, the captured image is stored in the image storage unit 72.

  In step S <b> 14, the angle information acquisition unit 51 acquires, from the angle information storage unit 71, information on the angle of the imaging device 1 at the time of shooting acquired from the sensor unit 16.

  In step S <b> 15, the image deformation processing unit 54 determines the strength of the image deformation processing according to the angle (up / down / front direction) of the imaging device 1 at the time of shooting acquired by the angle information acquisition unit 51. Specifically, the trimming processing unit 55 shoots the face from above when the angle of the imaging device 1 at the time of shooting is downward, so that the fine face effect is already easily exhibited. When the deformation process is not performed or the strength is weakened, and the angle of the imaging device 1 at the time of shooting is from the front, the strength of the image deformation processing is normal, and the angle of the imaging device 1 at the time of shooting is upward Since the face is photographed from below, the effect opposite to that of the narrow face is exhibited, so that the strength of the image deformation processing is made stronger than usual.

In step S <b> 16, the image deformation processing unit 54 determines whether or not to execute the image deformation processing of the present embodiment based on, for example, whether or not the user has performed an image deformation processing execution operation on the input unit 18.
When executing the image transformation process, it is determined as YES in Step S16, and the process proceeds to Step S17.
If the image transformation process is not executed, NO is determined in step S16, and the narrow face photographing process ends. At the end of the fine face photographing process, the captured image is stored in the image storage unit 72.

  In step S17, the trimming processing unit 55 sets the vicinity of the face jaw in the original image as a trimming region. Specifically, as shown in FIG. 3, the trimming processing unit 55 sets a peripheral region including the jaw centering on the lower part of the nose as the trimming region R1 in the original image P1.

In step S <b> 18, the trimming processing unit 55 performs a trimming process for trimming a set trimming area in the original image. Specifically, as shown in FIG. 3, the trimming processing unit 55 trims the set trimming region R1 from the original image P1.
As a result of the trimming process, a trimmed image composed of the trimming area of the original image is generated.

In step S <b> 19, the image deformation processing unit 54 performs image processing with the set distortion correction strength on the region near the jaw of the face in the trimmed image. Specifically, as shown in FIG. 3, the image transformation processing unit 54 uses the set distortion correction strengths (upward direction [none / weak], front side [standard], downward direction [strong]), and the trimmed image. Image deformation processing is performed such that the image is pulled radially toward the center of P2 (the lower part of the nose).
As a result of the image transformation process, an image is generated in which image processing for fine face correction is performed on the trimmed image.

  In step S <b> 20, the small face correction image generation unit 56 pastes the processed image on an area corresponding to the trimming area of the original image to generate a small face correction image. Specifically, as shown in FIG. 3, the fine face correction image generation unit 56 pastes the processed image P3 on the area R2 corresponding to the trimming area of the original image P1, thereby synthesizing the fine face correction image P4. Generate.

In step S <b> 21, the small face correction image generation unit 56 stores the small face correction image in the image storage unit 72.
Thereafter, the narrow face photographing process ends.
