That is, a frame image with a lacquer pattern is associated with the use environment A, a Western-style frame image is associated with the use environments B and D, and a Japanese-style frame image is associated with the use environment C. ing.

  The display control unit 14 causes the display unit 30 to display an ornamental image. In addition, the display control unit 14 causes the display unit 30 to display the frame image of the type set by the frame setting unit 13 together with the ornamental image in a state of being arranged on the outer periphery of the ornamental image. The display control unit 14 is realized by the CPU 101 shown in FIG.

  The storage unit 15 is a captured image acquired by the imaging unit 40 or a display image when the display control unit 14 causes the display unit 30 to display a framed image in which a frame image is arranged on the outer periphery of the ornamental image. Store data temporarily. The storage unit 15 is realized by the RAM 103 illustrated in FIG.

  In the DPF 1 configured as described above, a specific display mode for displaying a frame image around the ornamental image when the ornamental image is displayed is provided as a display mode. A specific display mode is set by the user operating the operation switch 5 in a predetermined procedure.

  Hereinafter, an operation when any image (photograph) recorded on the recording medium 50 is displayed as an ornamental image in a state where a specific display mode is set will be described. Note that the image to be displayed is, for example, selected by the user by a predetermined key operation.

  FIG. 5 is a flowchart showing the contents of processing executed by the control unit 10 (CPU 101) in accordance with the display control program 102a stored in the ROM 102 in a specific display mode.

  In the specific display mode, the control unit 10 first reads image data representing an ornamental image from the recording medium 50 and temporarily stores it in the storage unit 15 (RAM 103) (step S1).

  Next, the environment determination unit 11 (CPU 101) causes the photographing unit 40 (built-in camera 401) to photograph the situation on the front side of the DPF 1, and uses photographed image data representing the photographed image supplied from the photographing unit 40 to use the DPF 1. Obtained as environment information indicating the environment (step S2). The environment determination unit 11 stores the acquired captured image data in the storage unit 15 (103).

  Subsequently, the subject recognition unit 12 (CPU 101) recognizes the infant's face using the captured image data stored in the storage unit 15 as a processing target (step S3). In the process of step S3, the subject recognition unit 12 detects a face area, which is an area where a human face exists, in the captured image represented by the captured image data, and then determines the age from the detected face area, It is determined whether or not the face in the face area is an infant's face.

  The method of detecting the face area by the subject recognition unit 12 is a method in which an eye, nose, or mouth in a certain range of positional relationship exists by image recognition techniques such as binarization, contour extraction, and pattern matching, for example. This is a method to which a known technique for detecting an area as a face area is applied. In addition, the method for determining the age by the subject recognizing unit 12 is to determine race, age, gender, and the like by arithmetic processing using feature points constituting the facial organ described in Japanese Patent Application Laid-Open No. 2007-280291. This is a method to which a known technique is applied.

  When the subject recognition unit 12 succeeds in recognizing the infant's face in the process of step S3 (step S4: YES), the environment determination unit 11 indicates that the current usage environment is “the viewer is an infant”. It is determined that the usage environment A (see FIG. 4) is used as the prescribed condition (step S5). Further, the frame setting unit 13 (CPU 101) sets a frame image with a character pattern corresponding to the use environment A as a display target (step S6).

  Thereafter, the display control unit 14 (CPU 101) generates display image data representing a display image in which a frame image with a character pattern is arranged on the outer periphery of the appreciation image in the storage unit 15, and displays the generated image data. The image is sent to the unit 30 (display 301), and an image with a frame is displayed on the display unit 30 (step S17).

  FIG. 6A illustrates a frame displayed by the display unit 30 when the environment determination unit 11 determines that the current use environment is the use environment A with “the viewer is an infant” as a specified condition. It is the figure which showed the example of the attached image for convenience. That is, it is a diagram showing a framed image GA in which a frame image Ga with a character pattern is arranged on the outer periphery of the appreciation image G.

  If the subject recognition unit 12 cannot recognize the infant's face in the process of step S3 (step S4: NO), the subject recognition unit 12 continues to process the captured image data stored in the storage unit 15 as a processing target. A face is recognized (step S7). In the process of step S7, the subject recognition unit 12 determines the race from the face area face that has already been detected in the process of step S3, and determines whether the face area face is a Western face. The race recognition method by the subject recognizing unit 12 also discriminates race, age, gender, and the like by arithmetic processing using feature points constituting the facial organ described in Japanese Patent Application Laid-Open No. 2007-280291. This is a method using a known technique or the like.

  When the subject recognition unit 12 succeeds in recognizing the Western face in the process of step S7 (step S8: YES), the environment determination unit 11 indicates that the current usage environment is “the observer is a westerner”. "Is used environment B (see FIG. 4) with the prescribed condition (step S9). Further, the frame setting unit 13 sets a Western-style frame image corresponding to the use environment B as a display target (step S10).

  Thereafter, the display control unit 14 generates display image data representing a display image in which a Western-style frame image is arranged on the outer periphery of the viewing image in the storage unit 15, and sends the generated image data to the display unit 30. An image with a frame is displayed on the display unit 30 (step S17).

  6B, when the environment determination unit 11 determines that the current use environment is the use environment B with “the observer is a Westerner” as a specified condition, the display unit 30 displays the display. It is the figure which showed the example of the image with a frame for convenience. That is, it is a diagram showing a frame-added image GB in which a Western-style frame image Gb is arranged on the outer periphery of the appreciation image G.

  If the face of the infant cannot be recognized in the process of step S7 (step S8: NO), the subject recognition unit 12 continues to use the photographed image data stored in the storage unit 15 as a processing target. Recognize the shoji and tatami (step S11).

  A method for recognizing a Japanese-style room specific object by the subject recognition unit 12 is a method in which a known technique such as binarization, contour extraction, pattern matching, or the like is applied to an image to be detected. More specifically, the subject recognition unit 12 performs binarization and contour extraction processing on the captured image data. Next, the subject recognizing unit 12 uses template data representing a feature such as a pattern that is a reference for a Japanese-style room thing stored in the ROM 102, and in the captured image data, the image in the image having the feature represented by the template data is used. A process of detecting one or a plurality of area portions is performed. Then, the subject recognizing unit 12 determines that the detected region portion is a Japanese-style room-specific object if the degree of coincidence with the feature represented by the template data in the detected one or more region portions is a certain degree or more. To do.

  When the subject recognizing unit 12 succeeds in recognizing the Japanese-style room specific item in the process of step S11 (step S12: YES), the environment determining unit 11 defines that the current use environment is “Japanese-style room specific item exists”. It is determined that the usage environment C is a condition (see FIG. 4) (step S13). Further, the frame setting unit 13 sets a Japanese-style frame image corresponding to the use environment C as a display target (step S14).

  Thereafter, the display control unit 14 generates display image data representing a display image in which a Japanese-style frame image is arranged on the outer periphery of the viewing image, and sends the generated image data to the display unit 30. An image with a frame is displayed on the display unit 30 (step S17).

  FIG. 6C shows a frame with a frame displayed by the display unit 30 when the environment determination unit 11 determines that the current use environment is the use environment C with “there is a unique Japanese-style room” as a specified condition. It is the figure which showed the example of the image for convenience. That is, it is a diagram showing a framed image GC in which a Japanese-style frame image Gc is arranged on the outer periphery of the viewing image G.

  In addition, when the subject recognition unit 12 cannot recognize the unique Japanese-style room in the process of step S11 (step S12: NO), the environment determination unit 11 defines that the current use environment is “no special Japanese-style room”. It is determined that the usage environment D is a condition (see FIG. 4) (step S15). Further, the frame setting unit 13 sets a Western-style frame image corresponding to the use environment D as a display target (step S116).

  Thereafter, the display control unit 14 generates display image data representing a display image in which a Western-style frame image is arranged on the outer periphery of the viewing image in the storage unit 15, and sends the generated image data to the display unit 30. An image with a frame is displayed on the display unit 30 (step S17).

  When the environment determination unit 11 determines that the current use environment is the use environment D having a prescribed condition that “there is no Japanese-style room special item”, the display unit 30 displays the information in FIG. The framed image GC shown in FIG.

  As described above, in the DPF 1 of the present embodiment, when displaying an appreciation image, the current usage environment is determined by recognizing a specific subject from the captured image acquired by the imaging unit 40, and is associated with the current usage environment. The displayed frame image is automatically displayed on the outer periphery of the viewing image. That is, the DPF 1 automatically changes the frame image on the basis of the content related to the subject in the captured image. Therefore, different types of frames can be selectively displayed on the outer periphery of the viewing image without forcing the user to perform troublesome work.

  Moreover, the type of frame image displayed on the outer periphery of the viewing image by the DPF 1 is a type corresponding to the usage environment corresponding to the current usage environment among the predetermined usage environments (A to D). Therefore, the DPF 1 can automatically display a frame image of a type suitable for the usage environment on the outer periphery of the viewing image when displaying the viewing image. For example, when the observer is an infant, the DPF 1 can automatically display a frame image of a character pattern in which a pattern by a character that the infant is likely to like is arranged together with an appreciation image.

  In addition, the DPF 1 recognizes a plurality of specific subjects included in the predetermined conditions for defining each use environment in the order determined, and appreciates when one of the subjects is successfully recognized. Sets the type of frame image to be displayed on the outer periphery of the image. That is, the recognition operation is finished when one of the subjects is successfully recognized. Therefore, the recognition operation of the specific subject with respect to the captured image is minimal, and the current use environment can be determined efficiently.

(Deformation etc.)
In the present embodiment, a case has been described in which a plurality of predetermined use environments are the use environments A and B related to the type of viewer and the use environments C and D related to the type of room in the use place. However, the DPF 1 may be assumed to have only a plurality of usage environments related to the type of viewer, or may only be assumed to be related to the type of room at the usage location.

  In addition, specific contents of a plurality of usage environments and the number of usage environments can be changed as appropriate. In the DPF 1, use environments other than those related to the type of viewer and the type of room at the use place may be determined in advance as a plurality of use environments. In addition, specific types of frame images corresponding to a plurality of predetermined use environments can be changed as appropriate. In addition, a specific subject under conditions that define a plurality of use environments can be changed as appropriate.

  In the present embodiment, the case where the present invention is applied to a DPF that displays an image recorded as image data has been described. However, the present invention can be applied to any device as long as it has a function of displaying a frame image on the outer periphery of the ornamental image. Optional devices include digital cameras, mobile phone terminals with cameras, and the like.
