  By the way, the image management apparatus having such a configuration stores, for example, a still image formed in a rectangular shape, and the still image is a part or all of a subject to be seen such as a human face, a building, or a landscape. (Hereafter, this is also called an object).

  Still images may be generated such that the lower direction of the image is parallel to the short direction of the still image (hereinafter also referred to as the image short direction), or the long direction of the still image (hereinafter referred to as this). Is also generated in parallel with the image longitudinal direction).

  Incidentally, the downward direction of a still image is a reference for displaying the still image in the correct display direction so that the shape of the object drawn in the still image is aligned with the top and bottom of the line of sight. It is.

  The image management apparatus, for example, sets a plurality of still images on the display screen of the display unit regardless of the orientation of the still images in the lower direction, the image longitudinal direction is parallel to the screen horizontal direction, and the image lateral direction is The list is displayed parallel to the vertical direction of the screen.

  Incidentally, in the following description, the horizontal direction of the display screen of the display unit is also referred to as a screen horizontal direction, and the vertical direction of the display screen is also referred to as a screen vertical direction.

  For this reason, for example, if there is a still image generated so that the lower direction of the image is parallel to the longitudinal direction of the image in a plurality of still images, the image management apparatus converts the still image to the vertical direction of another still image. It will be shown in a different landscape.

  Further, the image management apparatus, for example, even if there is a still image requested to be viewed sideways even though it is displayed vertically in a plurality of still images, the still image is requested Contrary to this, it will be shown in portrait orientation.

  Therefore, conventionally, as such an image management apparatus, when the operation unit is operated with a list of a plurality of still images displayed on the display unit, a desired still image is centered on the image center point accordingly. There is something that can be rotated.

  According to the image management apparatus configured as described above, when a plurality of still images are displayed in a list on the display unit, the still image is rotated in accordance with the operation of the operation unit, so that the still image can be displayed in a desired vertical orientation. It can be changed to landscape and displayed.

  However, in the image management apparatus having such a configuration, when there are a plurality of still images to be rotated among the still images displayed as a list on the display unit, the operation unit is configured to select and rotate such still images one by one. There was a problem that it was necessary to operate, and operability was poor.

  The present invention has been made in consideration of the above points, and intends to propose a display state setting device, a display state setting method, and a display state setting program capable of improving operability.

  In order to solve such a problem, in the present invention, a plurality of still images are recognized, a correction rotation angle for correcting the display orientation for each still image is detected based on the recognition result for each still image, and a plurality of still images are detected. When a still image is displayed, when one still image is selected from the plurality of still images and a designated rotation angle for rotating the selected still image is designated, the selected still image is displayed. Set to rotate the image to the specified rotation angle and select multiple still images other than the selected still image based on the specified rotation angle and the corrected rotation angle of each of the multiple still images. The displayed still image is set to be rotated and displayed so as to have the same display orientation as when rotated to the specified rotation angle.

  Therefore, in the present invention, by selecting only one still image from a plurality of still images and specifying a designated rotation angle, the plurality of still images are set to be rotated and displayed so that their display directions are aligned with each other. can do.

  According to the present invention, a plurality of still images are recognized, a correction rotation angle for correcting the display direction for each still image is detected based on the recognition result for each still image, and the plurality of still images are displayed. In the state, when one still image is selected from the plurality of still images and a designated rotation angle for rotating the selected still image is designated, the selected still image is rotated to the designated rotation angle. A plurality of still images other than the selected still image and the selected still image based on the designated rotation angle and the corrected rotation angle of each of the plurality of still images. By setting to rotate and display in the same display orientation as when rotating to the specified rotation angle, one still image is selected from a plurality of still images and the specified rotation angle is set. The display state setting device, the display state setting method, and the display can be set so that the plurality of still images can be rotated and displayed so as to align their display directions. A state setting program can be realized.

For example, the image display device 1 can communicate with a digital still camera (not shown) that holds an image file of a still image generated by taking a picture of a subject by wireless connection or wired connection.

  In addition, the image display device 1 includes a recording medium (not shown) on which a still image image file generated by taking a photograph of a subject such as a memory card mounted with a semiconductor memory or an optical disk is recorded. It can be loaded.

  The image display device 1 includes a control unit 2 made up of, for example, a CPU (Central Processing Unit). The control unit 2 stores various programs such as basic programs and application programs stored in a storage unit 3 such as a hard disk drive or a ROM (Read Only Memory) 4 in a RAM (Random Access Memory) 6 via a bus 5. read out.

  The control unit 2 controls the entire apparatus according to various programs developed on the RAM 6, and executes predetermined arithmetic processing and various processings according to various operations on the operation input unit 7 such as a remote controller by the user.

  As a result, when the digital still camera is connected to the image display device 1 via the external device interface 8 by wireless or wired connection, the control unit 2 communicates with the digital still camera via the external device interface 8.

  In this state, when an image file take-in command is input from the operation input unit 7 according to the operation of the operation input unit 7 by the user, the control unit 2 receives 1 or 0 from the digital still camera via the external device interface 8. Import multiple image files.

  The control unit 2 stores the image file in the storage unit 3 by sending the image file to the storage unit 3.

  In addition, when a recording medium is loaded in the image display device 1 and the image file take-in command is input from the operation input unit 7 according to the operation of the operation input unit 7 by the user, the control unit 2 One or more image files are read from the recording medium by the drive 9.

  The control unit 2 stores the image file in the storage unit 3 by sending the image file to the storage unit 3.

  In this way, the control unit 2 can capture a plurality of image files from the outside and store them in the storage unit 3.

  Incidentally, the control unit 2 manages a plurality of image files stored in the storage unit 3 in a management unit called a folder for each of one or a plurality of image files captured and stored by a single capture process.

  When storing a plurality of image files in the storage unit 3, the control unit 2 can display a list of a plurality of still images on the display unit 10 based on the plurality of image files. The control unit 2 can also display a single still image on the display unit 10 alone.

  Here, as shown in FIG. 2, the display unit 10 of the image display apparatus 1 has, for example, a rectangular display screen 10 </ b> A.

  In the image display device 1, in the display screen 10A of the display unit 10, one of the pair of long sides 10AT and 10AU facing each other is defined as the upper end of the screen, and the other is defined as the lower end of the screen.

  In the image display device 1, in the display screen 10A of the display unit 10, one of the pair of short sides 10AR and 10AL facing each other is defined as the right end of the screen and the other is defined as the left end of the screen.

  Incidentally, in the following description, the screen horizontal direction parallel to the pair of long sides in the display screen 10A of the display unit 10 (that is, both the direction from the screen right end toward the screen left end and the direction from the screen left end toward the screen right end) Also called screen horizontal direction.

  Further, in the following description, the screen vertical direction parallel to the pair of short sides in the display screen 10A of the display unit 10 (that is, both the direction from the screen upper end to the screen lower end and the direction from the screen lower end to the screen upper end) Also called the screen vertical direction.

  On the other hand, an image file (that is, an image file including still image data of a still image) stored in the storage unit 3 of the image display device 1 is generated by a digital still camera.

  As shown in FIG. 3, the digital still camera DSC has, for example, a cubic housing 15, a camera lens CL is disposed on the front surface 15A of the housing 15, and a display screen DP is disposed on the back surface 15B. Yes.

  In the digital still camera DSC, a shutter button SB is disposed on one of a pair of end faces 15C and 15D facing each other between the front face 15A and the back face 15B in the housing 15.

  Incidentally, in the following description, one end surface 15C on which the shutter button SB is disposed among a pair of end surfaces 15C and 15D facing each other between the front surface 15A and the back surface 15B in the housing 15 is also referred to as an upper end surface 15C. .

  In the following description, the other end surface 15D facing the upper end surface 15C in the housing 15 is also referred to as a lower end surface 15D.

  Further, in the following description, one end surface 15E of the pair of end surfaces 15E and 15F facing each other between the front surface 15A and the back surface 15B in the casing 15 of the digital still camera DSC is also referred to as a right side surface 15E. .

  Furthermore, in the following description, the other end surface 15F facing the right end surface 15E in the housing 15 is also referred to as a left side surface 15F.

  The digital still camera DSC having such a configuration captures a field-of-view image of a subject facing the front surface 15A through a camera lens CL during photographing.

  The digital still camera DSC generates a visual field image from a pair of long sides on the upper end surface 15C side and the lower end surface 15D side and a pair of short sides on the right side surface 15E side and the left side surface 15F side regardless of the housing holding posture. Still images SG <b> 1 and SG <b> 2 that are cut out into a formed rectangular shape are generated.

  As a result, the digital still camera DSC can be seen as a part of a rectangular shape or an object to be seen such as a human face, a building, a landscape, etc. (that is, a subject in this case, hereinafter referred to as an object). Still images SG1 and SG2 depicting shapes are generated.

  By the way, when the digital still camera DSC generates such rectangular still images SG1 and SG2, the still image SG1 and SG2 uniformly define the top, bottom, left and right for indicating the display direction at the time of display.

  That is, the digital still camera DSC defines one long side on the upper end surface 15C side in the still images SG1 and SG2 as the upper end of the image positioned on the upper end side of the screen, and the other long side on the lower end surface 15D side. The lower end of the image is defined as the lower end of the screen.

  The digital still camera DSC defines one short side on the right side 15E side in the still images SG1 and SG2 as the right end of the image positioned on the right end side of the screen, and the other short side on the left side 15F side. This is defined as the left end of the image located on the left end side of the screen.

  Incidentally, the digital still camera DSC is configured to display the data of each pixel in the still images SG1 and SG2 (hereinafter referred to as pixel data) in the still image data forming the still images SG1 and SG2 in the vertical and horizontal directions of the still images SG1 and SG2. Stipulated) and the like.

  In the following description, in the still images SG1 and SG2, directions parallel to the long sides of the still images SG1 and SG2 (that is, both directions from the right end of the image to the left end of the image and from the left end of the image to the right end of the image). Is also called the image longitudinal direction.

  In the following description, in the still images SG1 and SG2, directions parallel to the short sides of the still images SG1 and SG2 (that is, both directions from the upper end of the image toward the lower end of the image and from the lower end of the image toward the upper end of the image). Is also referred to as the image lateral direction.

  However, although the digital still camera DSC regulates the top, bottom, left, and right of the still images SG1 and SG2, as described above, when a photograph is taken with the housing holding posture with the shutter button SB facing upward, the lower direction of the image is from the upper end of the image to the lower end of the image. A still image SG1 oriented in the direction is generated.

  Also, when a digital still camera DSC takes a picture with a housing holding posture in which the shutter button SB is directed to the right or left, the still image with the lower direction of the image facing from the left end of the image to the right end of the image or from the right end of the image to the left end of the image. An image SG2 is generated.

  As described above, the digital still camera DSC generates still images SG1 and SG2 having different image downward directions according to the housing holding posture at the time of taking a picture.

  Incidentally, the downward direction of the image is a reference for displaying the still images SG1 and SG2 in the correct display direction so that the top and bottom of the shape of the object drawn on the still images SG1 and SG2 are aligned with the top and bottom of the line of sight. It will be.

  In addition, when still images SG1 and SG2 are generated by taking a picture of a subject with the digital still camera DSC in this way, the downward direction of the image is a vertical downward direction with respect to the visual field image at the time of taking the picture.

  The digital still camera DSC includes the still image data of the still images SG1 and SG2 that define the top, bottom, left and right (that is, the upper end of the image, the lower end of the image, the left end of the image, and the right end of the image) as well as the still image data. Generate an image file.

  The image file generated by the digital still camera DSC is provided to the image display device 1 directly by the digital still camera DSC or by a personal computer or the like that has captured the image file from the digital still camera DSC.

  The image file generated by the digital still camera DSC is recorded on the above-described recording medium by the digital still camera DSC or by a personal computer or the like that takes in the image file from the digital still camera DSC.

  Incidentally, even in a general display device such as a conventional image management device, the display screen of the display unit is similar to the display screen 10A of the display unit 10 of the image display device 1 according to the present embodiment. The right edge of the screen and the left edge of the screen are specified.

  In general display devices, a still image is displayed on the display screen according to the upper, lower, left, and right rules, the upper end of the image is positioned on the upper end of the screen, the lower end of the image is positioned on the lower end of the screen, and the right end of the image is positioned on the right end of the screen. The image is displayed in a display orientation in which the left end of the image is positioned on the left end side of the screen.

  That is, a general display device has a still image on a display screen, a longitudinal direction of the image is parallel to the horizontal direction of the screen, and a short side of the image is a vertical direction of the screen, regardless of the orientation of the still image in the downward direction. Display in a parallel display state.

  Therefore, when a display screen is viewed with the top of the line of sight on the top edge of the screen and the bottom of the line of sight on the bottom edge of the screen, a general display device displays a still image with the bottom of the image facing the bottom edge of the screen. It can be shown in the correct display orientation with the top and bottom of the object aligned vertically.

  However, when a display screen is viewed with the top of the line of sight on the top edge of the screen and the bottom of the line of sight on the bottom edge of the screen, however, a general display device displays a still image with the bottom of the image directed from the left edge of the screen to the right edge of the screen. The top and bottom and the top and bottom of the object are shown in different display orientations.

  In addition, when a display screen is viewed with a general display device with the upper side of the line of sight being the upper edge of the screen and the lower side of the line of sight being the lower side of the screen, still images with the lower direction from the right edge of the screen toward the left edge of the screen are also displayed. The top and bottom and the top and bottom of the object are shown in different display orientations.

  For this reason, the image display apparatus 1 positions the upper end of the image on the upper end side of the screen when displaying a still image on the display screen 10A, positions the lower end of the image on the lower end side of the screen, and positions the right end of the image on the right end side of the screen. A display direction in which the left end of the image is positioned on the left end side is set as a reference display direction.

  Then, when the image display device 1 displays a list of a plurality of still images on the display screen 10A, the desired still image is displayed, for example, rotated rightward from the display state in the reference display direction around the center point of the image. The orientation can be changed.

  In practice, as shown in FIG. 4, the image file GF is generated by adding header data HD to the header portion of the still image data SD of the still image, for example, according to Exif (Exchangeable image file format). .

  Such still image data SD is generated, for example, by taking a picture of a subject and performing uncompressed or compression-coding in JPEG (Joint Photographic Experts Group) format.

  The header data HD stores a file name unique to the image file GF including the header data HD.

  Furthermore, the header data HD stores shooting date / time information indicating the shooting date / time of the photo shooting, which is also the generation date / time of the still image data SD, as related information regarding the still image data SD to which the header data HD is added.

  Further, the header data HD stores various information such as mode information indicating a shooting mode at the time of taking a picture, which is the time when the still image data SD is generated, as related information regarding the still image data SD.

  Incidentally, the shooting mode is a shooting mode for shooting a person selected by the user at the time of taking a picture, a shooting mode for shooting a landscape, etc., and shooting conditions (shooting distance and exposure) according to the subject to be shot. Etc.).

  By the way, some digital still cameras detect the downward direction of a still image when the subject is photographed to generate a still image.

  In the header data HD, when the image file GF is generated by the digital still camera having such a configuration, downward information indicating the downward direction of the image detected for the still image is stored as related information of the still image.

  Incidentally, in a digital still camera having such a configuration, for example, when a still image is generated by taking a picture of a subject, a surface facing the vertically downward direction among the upper end surface, the lower end surface, the right side surface, and the left side surface of the housing is provided. A gravity sensor for detection is provided.

  When the digital still camera having such a configuration captures a photograph of a subject and generates a still image, the gravitational sensor detects a surface that faces downward in the vertical direction among the upper end surface, the lower end surface, the right side surface, and the left side surface of the housing. And detecting the downward direction of the still image based on the detection result.

  Actually, when a digital still camera having such a configuration detects that the lower end surface of the housing is oriented vertically downward during photography, the lower image direction of the still image is directed from the upper end of the image to the lower end of the image accordingly. Detect that the direction was

  In addition, when the digital still camera detects that the upper end surface of the housing is directed vertically downward when taking a picture, the image lower direction of the still image is accordingly directed from the lower end of the image to the upper end of the image. To detect.

  Furthermore, when the digital still camera detects that the right side surface of the housing is oriented vertically downward during photography, the image downward direction of the still image is accordingly directed from the left edge of the image to the right edge of the image. To detect.

  Furthermore, when the digital still camera detects that the left side surface of the housing is directed vertically downward when taking a picture, the image downward direction of the still image is directed from the right edge of the image to the left edge of the image accordingly. Is detected.

  Some digital still cameras detect the photographing position (as latitude and longitude) of a subject by the digital still camera using GPS (Global Positioning System) when photographing the subject.

  In the header data HD, when the image file GF is generated by the digital still camera having such a configuration, position information indicating a photographing position is stored as related information of a still image.

  When the control unit 2 stores the image file GF in the storage unit 3 and the user requests setting of a display state for a still image via the operation input unit 7, the control unit 2 stores the image file GF in the storage unit 3 from the storage unit 3. All the image files GF are read and temporarily recorded in the RAM 6.

  Then, the control unit 2 detects whether or not downward information is stored in the header data HD in all the image files GF.

  As a result, if no downward information is stored in the header data HD, the control unit 2 rotates a still image around the image center point in an image file GF including the header data HD in a process described later. No rotation information is associated with each other.

  Further, when the downward information is stored in the header data HD, the control unit 2 determines whether or not the downward direction of the image indicated by the downward direction information is a direction from the upper end of the still image toward the lower end of the image. .

  As a result, the control unit 2 rotates the still image with respect to the corresponding image file GF in the same way as described above when the image downward direction indicated by the downward direction information is the direction from the upper end of the still image toward the lower end of the image. No rotation information is associated with each other.

  In addition, when the image downward direction indicated by the downward direction information is different from the direction from the upper end of the still image toward the lower end of the image, the control unit 2 selects the still image based on the downward direction information as its image center point. For example, rotation information indicating a rotation angle for rotating in the right direction is generated.

  Incidentally, when the image lower direction indicated by the lower direction information is a direction from the lower end of the still image toward the upper end of the image, the control unit 2 generates rotation information with the rotation angle in the right direction being 180 degrees.

  Further, when the downward direction of the image indicated by the downward direction information is a direction from the left end of the still image toward the right end of the image, the control unit 2 generates rotation information with the rotation angle in the right direction being 270 degrees.

  Further, when the downward direction of the image indicated by the downward direction information is a direction from the right end of the still image to the left end of the still image, the control unit 2 generates rotation information with a rightward rotation angle of 90 degrees.

  When the control unit 2 generates the rotation information in this way, the control unit 2 temporarily records the rotation information in the RAM 6 in association with the image file GF for later-described processing.

  Next, the control unit 2 sequentially reads a plurality of still image data SD from the RAM 6 and removes still image distortion and noise from the read plurality of still image data in order to improve the recognition accuracy of the image recognition processing. Then, a correction process for correcting the image quality is performed.

  In addition, the control unit 2 executes an image recognition process for recognizing the type of the still image based on the still image data, that is, what kind of object shape is the still image drawn.

  Here, the control unit 2 stores a database (hereinafter referred to as an image) in the storage unit 3 for managing a reference image (hereinafter also referred to as a recognition reference image) on which an object shape is drawn for image recognition. (Also called management database).

  Then, the control unit 2 registers the recognition reference image data of a plurality of types of recognition reference images in which the shapes of different objects are drawn in the image management database, and the recognition reference image data of the plurality of types of recognition reference images. Is stored in the storage unit 3.

  Actually, the control unit 2 has a plurality of objects such as humans, beasts, birds, fishes, insects, etc., and creatures such as plants such as flowers, trees, etc., as objects for image recognition. The recognition reference image data of the recognition reference image is stored in association with the name of the object.

  The control unit 2 also stores the recognition reference image data of a plurality of recognition reference images in which symbols such as characters and figures are drawn as image recognition objects in the storage unit 3 in association with the names of the objects. is doing.

  Furthermore, the control unit 2 also includes recognition reference image data of a plurality of recognition reference images in which the shape of a specific building such as a tourist attraction building or bridge is drawn as an object for image recognition with respect to the storage unit 3. It is stored in association with the name of the object. In the following explanation. Certain buildings such as tourist attractions and bridges are also called landmarks.

  Furthermore, the control unit 2 also recognizes the recognition reference image data of a plurality of recognition reference images in which the shape of an artifact such as a vehicle or a decoration is drawn as an object for image recognition with respect to the storage unit 3. It is stored in association.

  Furthermore, the control unit 2 also associates the recognition reference image data of a plurality of recognition reference images in which a figure of a landscape such as a countryside or a mountain range is drawn as an object for image recognition with respect to the storage unit 3 with the object name. I remember.

  These recognition reference image data are processed, for example, by processing original image data generated by taking a photograph of a real creature or a landmark as a subject, or original image data generated using computer graphics. Has been generated.

  By the way, the original image based on the original image data is generated by drawing the shape of the object so that the top, bottom, left and right are defined and the lower direction of the image is the direction from the upper end of the image to the lower end of the image.

  Further, the processing to be performed on the original image data for generating the recognition reference image data is for improving the recognition accuracy of the object, and includes dark place noise removal processing, contour extraction processing by Fourier transform, and the like.

  The processing is selected according to the type of the object, and the dark noise removal processing as the processing is performed, for example, in order to improve the recognition accuracy of the night view as the object. It is applied to the original image data of the image.

  In addition, the contour extraction process as the processing process is, for example, original image data of an original image on which a creature, a symbol, a landmark, or the like is drawn in order to improve recognition accuracy of a creature, a symbol, a landmark, or the like as an object. It is given to.

  By the way, the control unit 2 provides the storage unit 3 with, for example, a position indicating the location of the landmark in latitude and longitude in the recognition reference image data of the recognition reference image in which the shape of the landmark as an object is drawn. Information is stored in association with each other.

  Further, the control unit 2 stores the recognition reference image data of the recognition reference image in which a type of object that can be specified in the shooting mode at the time of taking a picture is drawn, such as a person or a landscape, with respect to the storage unit 3. Mode information indicating the shooting mode is stored in association with each other.

  The control unit 2 sequentially reads the still image data SD in the individual image files GF from the RAM 6 and reads image data by using the one still image data SD each time the still image data SD is read. Execute.

  Actually, every time one piece of still image data SD is read from the RAM 6, the control unit 2 determines whether or not the above-described rotation information is associated with the image file GF including the read still image data SD.

  As a result, if the rotation information is not associated with the image file GF including the still image data SD, the control unit 2 directly uses the still image based on the still image data SD as a recognition target.

  That is, the control unit 2 sets the still image as a recognition target in a state corresponding to the reference display direction when the still image is displayed on the display screen 10A according to the upper, lower, left, and right regulations as described above.

  Incidentally, in the following description, a state corresponding to a reference display direction in which a still image is displayed on the display screen 10A according to the upper, lower, left, and right regulations of the still image is also referred to as a reference display direction state.

  The reference display orientation state means, for example, that for convenience of explanation, when the horizontal direction and the vertical direction are set as invariable standards, in the still image, the image longitudinal direction is parallel to the horizontal direction and the image short direction is parallel to the vertical direction. Thus, the upper end of the image is positioned on the upper side in the vertical direction, and the lower end of the image is positioned on the lower side in the vertical direction.

  In contrast, when the rotation information is associated with the image file GF including the still image data SD, the control unit 2 performs rotation processing on the still image data SD according to the rotation information.

  Accordingly, the control unit 2 rotates the still image in the right direction indicated by the rotation information from the reference display orientation state around the image center point with respect to the still image data SD in the image file GF associated with the rotation information. Rotate by an angle and make it a recognition target.

  When the control unit 2 recognizes one still image as described above, for example, first, the still image data SD of the still image is subjected to binarization processing, and a still image (hereinafter, referred to as two colors) is expressed. This is also called a two-color image).

  Then, the control unit 2 determines whether or not the two-color image has only one color portion and the other color portion adjacent to each other with one straight boundary line as a boundary.

  As a result, if the two-color image has only one color part and the other color part adjacent to each other with one boundary line as a boundary, the recognition target still image is converted into an object. It is recognized that this is an image in which the horizon (or horizontal line) is drawn.

  However, for a still image in which the horizon (or horizontal line) as an object is drawn, for example, the portion of the ground (or sea surface) on the lower side of the image has a darker color than the sky portion.

  For this reason, for a two-color image obtained by binarizing a still image in which the horizon (or horizontal line) as an object is drawn, the color of the portion corresponding to the ground (or the sea surface) on the lower side of the image is The color is darker than the part corresponding to the sky.

  Therefore, when recognizing a still image, the control unit 2 detects whether or not the boundary line between one color portion and the other color portion is parallel to the horizontal direction in the two-color image.

  As a result, if the boundary line is parallel to the horizontal direction in the two-color image, the control unit 2 determines that the dark portion is located on the lower side in the vertical direction (that is, the lower image direction of the still image is the vertical direction). Or not).

  When the dark portion of the two-color image is positioned on the lower side in the vertical direction, the control unit 2 determines the rotation angle of the two-color image in the right direction from the reference display orientation state of the original still image. At the time of display, it is detected as a rotation angle capable of correcting the display direction so that the lower direction of the image is directed to the lower end of the screen.

  Incidentally, in the following description, when a still image is displayed, a rotation angle capable of correcting the display direction so that the lower direction of the image is directed to the lower end of the screen is also referred to as a corrected rotation angle.

  Then, the control unit 2 uses the corrected rotation angle (that is, the rotation angle in the right direction from the reference display orientation state) as rotation angle information used for displaying the still image to be recognized that is the source of the two-color image. .

  However, if the two-color image is not rotated from the reference display orientation state at this time, the control unit 2 generates rotation angle information indicating a correction rotation angle of 0 degrees.

  On the other hand, when the boundary line is parallel to the vertical direction in the two-color image, the control unit 2 makes the boundary line parallel to the horizontal direction and two colors in order to position the dark portion below the vertical direction. A correction rotation angle in the right direction for rotating the image from the reference display orientation state is detected.

  And the control part 2 makes the correction | amendment rotation angle to the detected right direction the rotation angle information utilized for the display of the still image of recognition object.

  When the control unit 2 recognizes the object drawn in the still image to be recognized in this way, the recognition is performed by associating the rotation angle information with the name of the recognized object (that is, the horizon (or horizontal line)). Generate result information.

  Then, the control unit 2 temporarily records the recognition result information in the RAM 6 so as to be associated with the still image data SD of the still image to be recognized.

  By the way, if the control unit 2 is different from an image in which the two-color image has only one color part and the other color part adjacent to each other with one boundary line as a boundary, A plurality of recognition reference image data is sequentially read out as a comparison target in a reading order selected in advance.

  Every time one piece of recognition reference image data is read from the storage unit 3, the control unit 2 applies the same processing process to the still image data SD of the recognition target still image as the processing used to generate the recognition reference image data. Apply.

  As a result, the control unit 2 changes the still image to be recognized to an image having the same property as the recognition reference image (that is, an image from which a contour has been extracted).

  In addition, the control unit 2 uses a pattern matching method according to the type of the object that can be recognized by the recognition reference image, and the still image (hereinafter also referred to as a processed still image) that has undergone the processing and the recognition reference image. The degree of similarity is obtained by comparison using a comparison method such as a cross-correlation function calculation method.

  Here, for example, the similarity indicates a value of “0” or more and “1” or less, and the similarity is lower as the value is closer to “0”, and the similarity is higher as the value is closer to “1”. It shows that.

  That is, for example, when a similarity of a value of “1” is obtained by comparing the still image with the recognition reference image, the still image includes the object drawn on the recognition reference image and the type and orientation (that is, the image downward direction). ) And the figure that matches the figure.

  For this reason, when the control unit 2 obtains the similarity between the processed still image and the recognition reference image in this way, the obtained similarity is, for example, as close as possible to a relatively large value (that is, a value of “1”). The value is compared with a first threshold value selected in advance.

  Therefore, when the control unit 2 obtains a similarity level equal to or higher than the first threshold, the still image to be recognized is a recognition reference image to be compared at this time (that is, a recognition standard that has obtained a similarity level equal to or higher than the first threshold). It is possible to accurately recognize that the image of the object indicated by (image) is drawn.

  When the control unit 2 recognizes the still image to be recognized in this manner, the control unit 2 detects the rotation angle in the right direction from the reference display orientation state with respect to the processed still image, and determines the recognition target that is the basis of the processed still image. The rotation angle information is used for displaying a still image.

  However, if the processed still image is not rotated from the reference display orientation state at this time, the control unit 2 generates rotation angle information indicating a rotation angle of 0 degrees.

  Further, when the similarity between the processed still image and the recognition reference image is smaller than the first threshold, the control unit 2 sets the processed still image to the center of the image center point, for example, 90 degrees sequentially in the right direction up to 270 degrees. While rotating, the similarity is obtained by comparing with the same recognition reference image by the same comparison method.

  The control unit 2 compares the obtained similarity with the first threshold value every time the similarity is obtained by comparing with the recognition reference image while sequentially rotating the processed still image in this way.

  In this way, when the control unit 2 obtains a similarity degree equal to or higher than the first threshold value in any state where the processed still image is rotated by 90 degrees, 180 degrees, and 270 degrees, the recognition target stationary image is obtained as described above. The image is recognized as an image in which the shape of the object indicated by the recognition reference image is drawn.

  When the control unit 2 recognizes the recognition target still image, the control unit 2 sets the rotation angle in the right direction from the reference display orientation state with respect to the processed still image when the recognition target still image is recognized, to the recognition target still image. Rotation angle information used for display.

  In this way, the control unit 2 can obtain the similarity by matching the lower direction of each image by comparing with the recognition reference image while appropriately rotating the still image to be recognized, thus recognizing the still image. The rate can be increased.

  When the control unit 2 recognizes the still image to be recognized and generates the rotation angle information, the control unit 2 generates the rotation angle information and the name of the object corresponding to the recognition reference image data to be compared at this time (that is, a creature or a landmark). And the like) are generated in association with each other.

  Then, the control unit 2 temporarily records the recognition result information in the RAM 6 so as to be associated with the still image data SD of the recognition target still image, and ends the image recognition processing for the recognition target still image.

  In this way, when the image recognition process for one recognition target still image is completed, the control unit 2 reads the next one still image data SD from the RAM 6 and executes the image recognition process in the same manner as described above.

  Further, the control unit 2 does not change the still image to be recognized and does not change the stored still image if the similarity is not less than the first threshold even if the processed still image is rotated to 270 degrees and compared with the recognition reference image. The next one recognition reference image data is read from the unit 3 and the comparison process is executed in the same manner as described above.

  By the way, even if the control unit 2 compares the still image to be recognized with all the recognition reference images, the control unit 2 cannot obtain a similarity equal to or higher than the first threshold (that is, the still image cannot be recognized). The image recognition process for the still image to be recognized is suspended.

  Also at this time, the control unit 2 reads the next one still image data SD from the RAM 6 and executes the image recognition processing in the same manner as described above.

  By the way, for example, when the contour extraction process is performed as the processing process on the still image to be recognized, the control unit 2 has a plurality of contour portions surrounded by different contours in the processed still image. Are compared to detect the largest contour portion.

  And the control part 2 calculates | requires a similarity so that the largest outline part detected in the process still image may be compared with a recognition reference image.

  As a result, the control unit 2 avoids an increase in processing load due to complicated comparison processing with the recognition reference image when there are a plurality of contour portions in the processed still image.

  Further, when the control unit 2 sequentially reads out a plurality of recognition reference image data from the storage unit 3 as a comparison target as described above, first, position information is included in the header data HD corresponding to the still image data SD of the still image to be recognized. Detect whether it is stored.

  When the position information is stored in the header data HD, the control unit 2 matches the photo shooting position indicated by the position information in the storage unit 3 or indicates a position within a predetermined range centered on the photo shooting position. It is detected whether or not recognition reference image data associated with the information is stored.

  As a result, the control unit 2 stores, in the storage unit 3, one piece of recognition reference image data that is associated with position information indicating a position that coincides with the photo shooting position or that is located within a predetermined range centered on the photo shooting position. If so, the recognition reference image data is first read from the storage unit 3.

  And the control part 2 performs a comparison process similarly to the above using the recognition reference | standard image data read from the memory | storage part 3 in this way.

  As a result, when the control unit 2 can recognize the still image to be recognized using the recognition reference image data, the control unit 2 generates the recognition result information in the same manner as described above, temporarily stores it in the RAM 6, and then The image recognition process for the still image ends.

  Then, the control unit 2 reads the next one still image data SD from the RAM 6 and executes an image recognition process in the same manner as described above.

  On the other hand, if the control unit 2 cannot recognize the recognition target still image using the recognition reference image data, the control unit 2 does not change the recognition target still image and changes the recognition reference image data from the storage unit 3. Other recognition reference image data other than the above are sequentially read in the above-described reading order.

  And the control part 2 performs a comparison process similarly to the above using the recognition reference | standard image data read sequentially from the memory | storage part 3. FIG.

  Further, the control unit 2 detects whether or not the mode information is stored in the header data HD when the position information is not stored in the header data HD corresponding to the still image data SD of the still image to be recognized. To do.

  As a result, if the mode information is not stored in the header data HD, the control unit 2 sequentially reads the plurality of recognition reference image data from the storage unit 3 in the above-described reading order, and performs the comparison process in the same manner as described above. Execute.

  On the other hand, when the mode information is stored in the header data HD, the control unit 2 recognizes reference reference image data in which the storage unit 3 is associated with mode information indicating a shooting mode that matches the shooting mode indicated by the mode information. Is detected.

  As a result, when the control unit 2 stores, for example, one piece of recognition reference image data in which the mode information indicating the shooting mode that matches the shooting mode at the time of shooting is stored in the storage unit 3, the storage unit 3, the recognition reference image data is read out.

  And the control part 2 performs a comparison process similarly to the above using the recognition reference | standard image data read from the memory | storage part 3 in this way.

  As a result, when the control unit 2 can recognize the still image to be recognized using the recognition reference image data, the control unit 2 generates the recognition result information in the same manner as described above, temporarily stores it in the RAM 6, and then The image recognition process for the still image ends.

  Then, the control unit 2 reads the next one still image data SD from the RAM 6 and executes an image recognition process in the same manner as described above.

  On the other hand, if the control unit 2 cannot recognize the recognition target still image using the recognition reference image data, the control unit 2 does not change the recognition target still image and changes the recognition reference image data from the storage unit 3. Other recognition reference image data other than the above are sequentially read in the above-described reading order.

  And the control part 2 performs a comparison process similarly to the above using the recognition reference | standard image data read sequentially from the memory | storage part 3. FIG.

  Incidentally, even if the position information is stored in the header data HD as described above, the control unit 2 continues to store the recognition reference image data associated with the corresponding position information in the storage unit 3. It is detected whether or not mode information is stored in the header data HD.

  Then, the control unit 2 continues to perform the same processing as when the mode information is stored in the header data HD as described above or when the mode information is not stored.

  In this way, when the control unit 2 sequentially compares the still image to be recognized with one recognition reference image, the control unit 2 preferentially uses the recognition reference image that has a high possibility of recognizing the still image. The number of executions is reduced as much as possible.

  By the way, when comparing the still image with the recognition reference image, the control unit 2 fixes the top, bottom, left and right of the recognition reference image. In addition, the control unit 2 is configured so that the top, bottom, left, and right of the still image are aligned with the top, bottom, left, and right of the recognition reference image only when the still image is compared with the recognition reference image as a recognition target without rotating.

  Further, the control unit 2 compares the still image with the recognition reference image by appropriately rotating only the still image without rotating the recognition reference image.

  Therefore, the control unit 2 compares the still image in which the same object is drawn with the recognition reference image, and when the image lower direction of the still image coincides with the image lower direction of the recognition reference image, the control unit 2 has the largest similarity. The still image can be recognized with a certain degree.

  For this reason, the control unit 2 also sets the rotation angle in the right direction from the reference display orientation state at the time of recognition with respect to the still image so that the lower direction of the image is directed to the lower end of the screen when the still image is displayed as described above. Can be detected as a correction rotation angle that can be corrected.

  The control unit 2 stores the corrected rotation angle detected when the still image is recognized (that is, the rotation angle in the right direction from the reference display orientation state) as rotation angle information.

  When there is a still image in which the object is drawn (that is, the image recognition process is suspended) when the image recognition process is completed, the control unit 2 does not recognize the still image. A similar image search process for searching for another still image similar to the image is executed.

  At this time, the control unit 2 sequentially reads still image data SD of still images that could not be recognized from the RAM 6 in the previous image recognition process.

  Then, every time one piece of still image data SD is read from the RAM 6, the control unit 2 executes a similar image search process using the one piece of still image data SD.

  Actually, every time one piece of still image data SD is read from the RAM 6, the control unit 2 determines whether or not the rotation information described above is associated with the image file GF including the read still image data SD.

  As a result, if the rotation information is not associated with the image file GF including the still image data SD, the control unit 2 uses the still image based on the still image data SD as a search source in the reference display orientation state.

  In contrast, when the rotation information is associated with the image file GF including the still image data SD, the control unit 2 performs rotation processing on the still image data SD according to the rotation information.

  Accordingly, the control unit 2 rotates the still image in the right direction indicated by the rotation information from the reference display orientation state around the image center point with respect to the still image data SD in the image file GF associated with the rotation information. Rotate only the angle and use it as a search source.

  Further, the control unit 2 extracts a contour extraction process or a texture (part of a specific pattern or color) from still image data (hereinafter also referred to as search source still image data) SD of a still image as a search source. An extraction process such as a process is performed.

  In this state, the control unit 2 reads the shooting date / time information in the header data HD corresponding to the still image data SD of the still image to be retrieved from the RAM 6 and the header data HD in the still image data SD of the recognized still image. The shooting date / time information is read out.

  In the following description, still image data SD of a recognized still image is also referred to as recognized still image data SD.

  Then, the control unit 2 sets the plurality of recognized still image data SD from the RAM 6 based on the respective shooting date / time information farthest from the one generated at the shooting date / time closest to the shooting date / time when the search source still image data SD was generated. Read out in the order up to the one generated on the shooting date.

  In this way, every time one piece of recognized still image data SD is read from the RAM 6, the control unit 2 also reads rotation angle information associated with the read recognized still image data SD.

  Then, the control unit 2 performs a rotation process on the recognized still image data SD according to the rotation angle information, so that the recognized still image based on the recognized still image data SD is centered on the image center point. Rotate as appropriate.

  In addition, the control unit 2 performs the same extraction process on the recognized still image data SD as described above, thereby converting the recognized still image into an image having the same property as the still image that is the search source (that is, contour or texture). Extracted images, etc.).

  In this state, the control unit 2 performs a retrieval source still image (hereinafter also referred to as a retrieval source extracted image) subjected to extraction processing, and a recognized still image (hereinafter referred to as recognized extraction) subjected to extraction processing. Are also compared by a comparison method such as a pattern matching method.

  When the control unit 2 determines the similarity between the search source extracted image and the recognized extracted image in this manner, the control unit 2 compares the calculated similarity with a second threshold value selected in advance.

  As a result, when the control unit 2 obtains a similarity level equal to or higher than the second threshold value, the recognized still image obtained with the similarity level equal to or higher than the second threshold value is similar in design to the still image of the search source. Judged to be an image.

  When the control unit 2 searches for a recognized still image similar in design to the still image of the search source in this way, the still image of the search source has the same object appearance as the recognized still image. Recognize that the image is a shape.

  When the control unit 2 recognizes the still image as the search source in this way, the rotation angle in the right direction from the reference display orientation state with respect to the search source extracted image is set to the still image of the search source that is the source of the search source extracted image. Rotation angle information used for image display.

  However, if the search source extraction image is not rotated from the reference display orientation state at this time, the control unit 2 generates rotation angle information indicating a rotation angle of 0 degrees.

  In addition, when the similarity between the search source extracted image and the recognized extracted image is smaller than the second threshold, the control unit 2 sequentially sets the search source extracted image to 270 degrees by 90 degrees in the right direction around the image center point. The degree of similarity is obtained by comparing with the same recognized extracted image by the same comparison method.

  The control unit 2 compares the obtained similarity with the second threshold every time the similarity is obtained by comparing with the recognized extracted image while sequentially rotating the search source extracted image in this way.

  As a result, when the control unit 2 obtains a similarity degree equal to or higher than the second threshold value in any state where the search source extracted image is rotated by 90 degrees, 180 degrees, and 270 degrees, the second threshold value is obtained as described above. It is determined that the recognized still image obtained with the above similarity is an image similar in design to the still image of the search source.

  In this way, when the control unit 2 searches for a recognized still image whose pattern is similar to that of the search source still image, the search source still image has the same object shape as the recognized still image. Is recognized as an image drawn.

  When the control unit 2 recognizes the still image of the search source, the control unit 2 sets the rotation angle in the right direction from the reference display orientation state with respect to the search source extracted image when the still image of the search source is recognized as the still image of the search source. Rotation angle information used for image display.

  In this way, the control unit 2 can obtain the similarity by aligning the lower direction of each image by comparing with the recognized extracted image while appropriately rotating the search source extracted image, and thus the patterns are similar. The search rate for still images can be increased.

  When the control unit 2 recognizes the still image of the search source and generates the rotation angle information, the control unit 2 generates the rotation angle information and the name of the object corresponding to the recognized still image searched at this time (that is, a creature, a landmark, or the like). The search result information is generated in association with each other.

  Then, the control unit 2 temporarily stores the search result information in the RAM 6 so as to be associated with the search source still image data SD of the search source still image, and performs similar image search processing using the search source still image. finish.

  In this way, when the similar image search processing using one search source still image is completed, the control unit 2 reads the next one search source still image data SD from the RAM 6 and performs similar image search in the same manner as described above. Execute the process.

  Further, the control unit 2 rotates the search source extracted image to 270 degrees and compares it with the recognized extracted image, and if the similarity equal to or higher than the second threshold is not obtained, the search source still image is not changed. Then, the next recognized still image data is read from the storage unit 3, and the comparison process is executed in the same manner as described above.

  By the way, the 2nd threshold value mentioned above is chosen as a value smaller than the 1st threshold value mentioned above, for example. Thus, even if there is a still image that cannot be recognized by the image recognition process, the control unit 2 can almost certainly recognize what the still image is in the similar image search process. Yes.

  Furthermore, for example, when taking a photograph of a subject using a digital still camera, the user is likely to take a picture of the same subject a plurality of times continuously while changing the composition.

  For this reason, the control unit 2 sequentially compares the still image of the search source in the similar image search process from the recognized still image generated at the shooting date and time that is closest to the shooting date and time when the still image of the search source was generated. I made it.

  Therefore, even if there is a still image that cannot be recognized by the image recognition process, the control unit 2 recognizes more accurately what kind of object the still image is drawn in the similar image search process. can do.

  In addition, when comparing the still image of the search source with the recognized still image, the control unit 2 appropriately rotates the recognized still image according to the rotation angle information.

  As a result, the control unit 2 fixes the recognized still image in the same direction as the image downward direction when the above-described recognition reference image is fixed for comparison.

  When the control unit 2 compares the still image of the search source with the recognized still image, the control unit 2 does not rotate the recognized still image in addition to the rotation using the rotation angle information. Rotate only the image as appropriate.

  Therefore, when the control unit 2 compares the still image of the search source in which the same object is drawn with the recognized still image, the control unit 2 obtains the highest degree of similarity when the lower direction of each image matches, A still image as a search source can be recognized.

  For this reason, the control unit 2 also sets the rotation angle in the right direction from the reference display orientation state at the time of recognition with respect to the still image as the search source so that the lower direction of the image is directed to the lower end of the screen when the still image is displayed as described above. It can be detected as a corrected rotation angle that can correct the display orientation.

  The control unit 2 also stores the corrected rotation angle detected when the still image as the search source is recognized (that is, the rotation angle in the right direction from the reference display orientation state) as the rotation angle information.

  In this way, when the similar image search process is completed for all still images that could not be recognized by the image recognition process, the control unit 2 then executes a classification process for classifying the still images into a plurality of groups.

  In this case, the control unit 2 reads all the recognition result information and search result information temporarily recorded in association with the still image data SD from the RAM 6.

  Further, the control unit 2 classifies all the still image data SD based on the type of object recognized for the still image based on the recognition result information and the search result information.

  Thereby, the control unit 2 converts the still image data SD between still images in which objects of the same type are drawn, such as still images in which human faces are drawn or still images in which a bridge is drawn, That is, the still images having similar patterns are grouped together.

  Then, the control unit 2 generates a data table (hereinafter also referred to as a display state setting table) used for setting the display state of still images based on the plurality of still image data SD stored as the image file GF in the storage unit 3. To do.

  As shown in FIG. 5, the display state setting table DT stores the file names FN of all the image files GF stored in the storage unit 3.

  In the display state setting table DT, group identification information GID capable of individually identifying the group into which the still image data SD in the image file GF is classified is stored in association with the file name FN of the image file GF. ing.

  In the display state setting table DT, the name ON of the object recognized for the still image based on the still image data SD in the image file GF is also stored in association with the file name FN of the image file GF.

  Further, in the display state setting table DT, the rotation angle information RT obtained when the object is recognized for the still image based on the still image data SD in the image file GF is also associated with the file name FN of the image file GF. Stored.

  Furthermore, the display state setting table DT also stores display presence / absence setting information SOF indicating whether still images are displayed based on the still image data SD in the image file GF, in association with the file name FN of the image file GF. Has been.

  When the control unit 2 generates the display state setting table DT having such a configuration, the control unit 2 is initially set to indicate that a corresponding still image is displayed for any of the display presence / absence setting information SOF stored in the display state setting table DT. It is set. Then, the control unit 2 sends the display state setting table DT to the storage unit 3 for storage.

  In this state, the control unit 2 reads a plurality of still image data SD from the RAM 6. Further, based on the plurality of still image data SD, the control unit 2 generates display image data for collectively displaying a plurality of still images based on the plurality of still image data SD in a reference display direction.

  Then, the control unit 2 sends the display image data to the display unit 10, whereby a plurality of still images based on the plurality of still image data SD are respectively displayed on the display screen 10 </ b> A of the display unit 10 based on the display image data. Place them in the standard display direction and display them all together.

  However, the control unit 2 arranges a plurality of still images on the display screen 10A based on the display image data in any one of three types of display forms, for example, one line display, list display, and group display. It can be displayed.

  Then, the control unit 2 allows the user to arbitrarily select the display screen 10A of the display unit 10 via the operation input unit 7 as to which of the three types of display forms is to be displayed. ing.

  As shown in FIG. 6, when the user selects the single-line display, the control unit 2 displays display image data for single-line display (hereinafter also referred to as single-line display image data) based on the plurality of still image data SD. Generate.

  Then, the control unit 2 sends the single-row display image data to the display unit 10 to display the single-row display image 20 based on the single-row display image data on the display screen 10A.

  In this case, in the one-line display image 20, for example, a plurality of still images SG are displayed in a line parallel to the vertical direction of the screen near the left end of the screen.

  Further, in the one-line display image 20, a character string indicating the file name of the corresponding image file GF and the photographing date and time of the photographing is displayed on the right side of each still image SG.

  Incidentally, when the user inputs a scroll command via the operation input unit 7 in a state where the one-line display image 20 is displayed on the display screen 10A, the control unit 2 displays the one-line display image 20 on the display screen 10A. Scroll (ie move) in the direction.

  Thereby, the control unit 2 appropriately changes the still images SG displayed on the display screen 10A even when a plurality of still images SG cannot be displayed at once as the one-line display image 20 on the display screen 10A. A plurality of still images SG can be shown.

  As shown in FIG. 7, when the list display is selected by the user, the control unit 2 displays display image data for list display based on a plurality of still image data SD (hereinafter also referred to as list display image data). Is generated.

  Then, the control unit 2 displays the list display image 21 based on the list display image data on the display screen 10A by sending the list display image data to the display unit 10.

  In this case, the list display image 21 displays a plurality of still images SG arranged in a matrix of a plurality of rows and a plurality of columns.

  Incidentally, even when the list display image 21 is displayed on the display screen 10A, the control unit 2 displays the list display image 21 on the display screen 10A when a scroll command is input via the operation input unit 7. Scroll vertically.

  As a result, even when the plurality of still images SG cannot be displayed as the list display image 21 on the display screen 10A at one time, the control unit 2 appropriately changes the still images SG displayed on the display screen 10A. A plurality of still images SG can be shown.

  Further, as shown in FIG. 8, when the display by group is selected by the user, the control unit 2 divides the plurality of still images SG into groups based on the display state setting table DT, for example.

  The control unit 2 generates display image data for group display (hereinafter also referred to as group display image data) based on the plurality of still image data SD divided into the groups.

  And the control part 2 displays the display image 22 classified by group based on the display image data classified by group on the display screen 10A by sending the display image data classified by group to the display part 10. FIG.

  In this case, in the group-specific display image 22, for example, one or more still images SG for each group are arranged in parallel to the horizontal direction of the screen from the vicinity of the left end of the screen toward the right end of the screen, and as a whole, in a plurality of rows. Arranged and displayed.

  The control unit 2 displays the group-specific display image 22 on the display screen 10A when a scroll command is input via the operation input unit 7 while the group-specific display image 22 is displayed on the display screen 10A. Scroll vertically or horizontally across the screen.

  Thereby, the control unit 2 appropriately changes the still image SG displayed on the display screen 10A even when a plurality of still images SG cannot be displayed as the group-specific display images 22 on the display screen 10A at one time. These multiple still images SG can be shown.

  The control unit 2 performs processing that can be executed for setting the display state together with the plurality of still images SG on the display screen 10A, regardless of the display form in which the plurality of still images SG are displayed on the display screen 10A. Displays a menu showing the items.

  Thus, the control unit 2 causes the display screen 10A to select various processes for setting the display state while viewing the plurality of still screens SG, and executes the selected processes to display a plurality of still images as desired. It can be set to the state.

  Here, a menu showing items of processing that can be executed for display state setting will be described with reference to FIG. The menu includes an option menu indicating items of processing that can be executed for all still images SG.

  In addition, as such a menu, there is also a group menu indicating items of processing that can be executed on the still image SG for each group. Furthermore, as such a menu, there is also an individual menu showing items of processing that can be executed for each still image SG.

  That is, the control unit 2 is configured to execute the management mode changing process for changing the management mode of the plurality of still images SG only when the group-specific display image 22 is displayed on the display screen 10A.

  In the group menu, in the arbitrarily selected group, settings other than one arbitrarily selected still image SG are set to non-display, that is, one arbitrarily selected still image SG is set to be displayed alone. There is a single display setting item.

  The group menu also has a group unit rotation setting item for setting all still images SG belonging to an arbitrarily selected group to be rotated and displayed around the image center point.

  Further, the group menu also has a comparison display item for simultaneously displaying one still image SG arbitrarily selected and another still image SG in the arbitrarily selected group for comparison.

  Further, the group menu also includes a batch deletion item for collectively deleting one or a plurality of still images SG that are arbitrarily selected in a group that is arbitrarily selected.

  Further, the group menu includes a group movement for moving (that is, reclassifying) one or a plurality of still images SG that are arbitrarily selected in the arbitrarily selected group to another group that is arbitrarily selected. There is also an item.

  Further, in the group menu, in the arbitrarily selected group, one or more still images SG that are arbitrarily selected are removed from the group, and a new group to which the selected one or more still images SG belong. There is also a group creation item for creating.

  The individual menu includes a non-display setting item for individually setting one still image SG selected arbitrarily to non-display.

  The individual menu also includes an individual rotation setting item for setting the arbitrarily selected still image SG to be rotated and displayed around the center point of the image.

  Further, the individual menu includes individual display items for individually displaying one still image SG selected arbitrarily on the display screen 10A.

  Further, the individual menu includes an individual deletion item for individually deleting one still image SG that is arbitrarily selected.

  Actually, the control unit 2 generates, for example, first-line display image data according to the storage of the display state setting table DT in the storage unit 3 and sends it to the display unit 10 to display the display screen 10A on FIG. The displayed one-line display image 20 is displayed.

  In this state, when the display unit is requested by the user via the operation input unit 7, the control unit 2 reads the menu data stored in advance from the storage unit 3 and stores the menu data in a plurality of still image data SD. Menu synthesized image data is generated by synthesizing the menu data.

  Then, the control unit 2 sends the menu composite image data to the display unit 10 to display the menu composite image 25 as shown in FIG. 10 on the display screen 10A of the display unit 10 based on the menu composite image data.

  Furthermore, in the following description, the icon 36 corresponding to the group creation item in the group menu is also referred to as a group creation icon 36.

  In the menu image 26, the display form switching icon 28 displays a character string indicating the currently selected display form (in this case, a character string called single line display).

  In the menu image 26, the all image rotation icon 29 is a character string (in this case, for example, all of the still images SG or some of the still images SG that can be selected as a rotation target). A character string (image or partial image) is displayed.

  Further, in the menu image 26, the sort icon 30 displays a character string indicating the currently selected sort order (in this case, for example, a character string in the order of file names).

  Further, in the menu image 26, the single display icon 31 displays a character string (in this case, a character string called single display) indicating that the process selectable by the single display icon 31 is the single display setting process. .

  In the menu image 26, the group unit rotation icon 32 has a character string (in this case, a character string called group unit rotation) indicating that the process selectable by the group unit rotation icon 32 is a group unit rotation setting process. It is displayed.

  Furthermore, in the menu image 26, the comparison display icon 33 displays a character string (in this case, a character string called comparison display) indicating that the process selectable by the comparison display icon 33 is a comparison display process.

  Further, in the menu image 26, the batch deletion icon 34 displays a character string (in this case, a character string called batch deletion) indicating that the process selectable by the batch deletion icon 34 is a batch deletion process.

  Further, in the menu image 26, the group movement icon 35 displays a character string (in this case, a character string called group movement) indicating that the process selectable by the group movement icon 35 is a group movement process.

  Further, in the menu image 26, the group creation icon 36 displays a character string (in this case, a character string called group creation) indicating that the process selectable by the group creation icon 36 is a group creation process.

  On the other hand, the selection image 27 is provided with a group menu selection button 37 for selecting a group menu and an individual menu selection button 38 for selecting an individual menu.

  When the menu composite image 25 is displayed on the display screen 10A, the control unit 2 displays a plurality of still images SG arranged in order of file names, for example, in a row as an initial state.

  Therefore, when the menu composite image 25 is displayed on the display screen 10 </ b> A, the control unit 2 displays a character string in the order of file names as an initial state in the sort icon 30.

  In this state, when the sort icon 30 is selected on the menu composite image 25 by the user via the operation input unit 7, the control unit 2 sets the order of the plurality of still images SG in the order of file name, shooting date / time, group A pull-down menu (not shown) in which the order can be arbitrarily selected is displayed.

  When the user selects the shooting date / time order or group order on the pull-down menu via the operation input unit 7, the control unit 2 selects a plurality of still images SG in the menu composite image 25 as the selected shooting date / time. Sort by order or group order.

  Incidentally, when the control unit 2 sorts the plurality of still images SG in this way, the control unit 2 changes the display in the sort icon 30 to indicate the order used for the sorting.

  When the menu composite image 25 is displayed on the display screen 10A, the control unit 2 rotates and displays a part of the still images SG as individual or group units arbitrarily selected as a rotation target as an initial state. This is a partial image rotation display setting mode for setting as follows.

  Then, the control unit 2 displays, for example, a character string “partial image” indicating the partial image rotation display setting mode as an initial state in the full image rotation icon 29 in the menu composite image 25 displayed on the display screen 10A. is doing.

  In this state, when the user selects the all-image rotation icon 29 on the menu composite image 25 via the operation input unit 7, the control unit 2 sets all the still images SG to be rotated and displayed. Shift to the all image rotation display setting mode.

  At this time, the control unit 2 displays, for example, a character string of “all images” in the all-image rotation icon 29 in the menu composite image 25 indicating that the mode has shifted to the all-image rotation display setting mode.

  In this state, when the user instructs to set the rotation display of the still image SG via the operation input unit 7, the control unit 2 selects all the still images SG as rotation targets at once.

  Then, the control unit 2 generates rotation setting information indicating that the still image SG is rotated and displayed according to the rotation angle information, and associates the rotation setting information with all file names in the display state setting table DT. And add.

  As a result, the control unit 2 sets all these still images SG so as to be rotated and displayed according to the corresponding rotation angle information so that the lower direction of the image is in the display direction facing the lower end of the screen.

  Note that the correction rotation angle is “0” degrees for the still image SG that originally has the reference display direction and the image lower direction faces the screen lower direction. Therefore, for the still image SG, the display state according to the setting for rotating and displaying the still image SG as it is so that the lower direction of the image faces the lower end of the screen according to the rotation angle information is maintained as it is. become.

  Incidentally, at this time, the control unit 2 performs a rotation process on all the still image data SD according to the rotation angle information actually corresponding thereto. Thereby, the control unit 2 displays all the still images SG on the menu composite image 25 by rotating them so that the lower direction of the image is in the display direction facing the lower end of the screen, and the display state of all these still images SG is displayed. It can be confirmed.

  By the way, when the all image rotation icon 29 is selected on the menu composite image 25 by the user via the operation input unit 7 in the all image rotation display setting mode, the control unit 2 again shifts to the partial image rotation display setting mode. To do.

  At this time, the control unit 2 displays the character string “partial image” again in the all-image rotation icon 29 in the menu composite image 25 instead of the character string “all image”.

  When the group unit rotation icon 32 is selected on the menu composite image 25 by the user via the operation input unit 7 in the partial image rotation display setting mode, the control unit 2 rotates the still image SG in units of groups. Moves to the group unit rotation display setting mode to be set.

  In this state, when one still image SG is arbitrarily selected on the menu composite image 25 by the user via the operation input unit 7, the control unit 2 belongs to the still image SG based on the display state setting table DT. A group and other still images SG belonging to the group are searched.

  Further, the control unit 2 surrounds all the still images SG belonging to the searched group in the menu composite image 25 with a frame of a predetermined first color.

  Thereby, the control unit 2 confirms all still images SG belonging to the searched group in the menu composite image 25 by easily distinguishing them from the still images SG belonging to other groups by the first color frame. Can be made.

  Incidentally, the group searched according to the selection of one still image SG by the user is also a group selected by the user using the still image SG. Therefore, in the following description, a group searched according to selection of one still image SG is also referred to as a selection group.

  Further, at this time, the control unit 2 automatically sets all the still images SG belonging to the selected group as rotation targets. Then, the control unit 2 displays a check box, for example, in the upper right corner of all the still images SG belonging to the selected group in the menu composite image 25, and all these still images SG are rotation targets in the check box. A check mark is displayed to indicate this.

  In this state, when one still image SG is arbitrarily selected from the selected group on the menu composite image 25 by the user via the operation input unit 7, the control unit 2 displays the selected one still image SG. The frame is surrounded by a frame of a predetermined second color different from the first color.

  Incidentally, in the following description, one still image SG further arbitrarily selected within one arbitrarily selected group (that is, a selection group) is also particularly referred to as a selected image.

  Thereby, the control part 2 can make a selection image distinguish easily from other still images SG within a selection group in the menu synthetic | combination image 25, and can confirm it.

  By the way, when the selected image is arbitrarily selected on the menu composite image 25, the control unit 2 makes a desired rotation angle (for example, 0 degrees, 90 degrees, 180 degrees) in the right direction from the reference display direction with respect to the selected image. Degrees, 270 degrees) can be arbitrarily designated.

  Incidentally, in the following description, the rotation angle in the right direction from the reference display direction designated for the selected image by the user is also referred to as a designated rotation angle.

  When the designated rotation angle for the selected image is arbitrarily designated by the user via the operation input unit 7, the control unit 2 subtracts the designated rotation angle from the correction rotation angle in the right direction indicated by the corresponding rotation angle information. To find the angle difference.

  Further, the control unit 2 subtracts the obtained angle difference from the corrected rotation angle in the right direction indicated by the rotation angle information corresponding to each of the other still images SG belonging to the selected group.

  As a result, the control unit 2 makes the other image such that the lower direction of the other still images SG belonging to the selected group matches the lower direction of the selected image when the selected image is rotated to the specified rotation angle. The rotation angle of the still image SG in the right direction from the reference display direction is obtained.

  Incidentally, in the following description, the rotation angle in the right direction from the reference display direction obtained for another still image SG is also referred to as a detected rotation angle.

  In this state, the control unit 2 generates rotation setting information indicating that the still image SG is rotated and displayed when the user inputs an instruction to rotate the still image SG via the operation input unit 7. .

  Then, the control unit 2 adds the rotation setting information to the display state setting table DT so as to be associated with the file name.

  However, if the designated rotation angle or the detected rotation angle of the still image SG is different from the correction rotation angle in the right direction indicated by the corresponding rotation angle information, the control unit 2 makes the specified rotation angle or New rotation angle information indicating the detected rotation angle is added in association with the file name.

  In this case, the control unit 2 adds rotation setting information indicating rotation angle information used for rotation of the still image SG to the display state setting table DT so as to be associated with the file name.

  As a result, the control unit 2 sets the selected images belonging to the selected group to be rotated and displayed at the designated rotation angle. In addition, the control unit 2 sets the other still images SG belonging to the selected group to be rotated and displayed at the corresponding detection rotation angles.

  In this way, the control unit 2 causes all the still images SG belonging to the selected group to have a display orientation in which the lower direction of the still images SG is directed in the same direction only by designating the designated rotation angle of the selected image. Rotate to set to display.

  However, even if the selected group is selected by the user, the control unit 2 displays all the still images SG belonging to the selected group in the downward direction when rotation setting is commanded without selecting the selected image within the selected group. Is set to rotate and display so that the screen is oriented toward the bottom of the screen.

  In other words, the control unit 2 selects the user only when setting all the still images SG belonging to the selected group to be rotated and displayed so that the lower image direction is the lower screen direction. Even if an image is not selected and a rotation display setting is instructed, it can be realized.

  Incidentally, when setting the rotation display in units of groups, the control unit 2 performs the rotation process according to the designated rotation angle, the detected rotation angle, or the rotation angle information that actually corresponds to all the still image data SD belonging to the selected group. Apply.

  In the following description, the icon 40 corresponding to the non-display setting item of the individual menu is also referred to as the non-display setting icon 40, and the icon 41 corresponding to the individual rotation setting item of the individual menu is also referred to as the individual rotation setting icon 41. Call.

  In the following description, the icon 42 corresponding to the individual display item of the individual menu is also referred to as an individual display icon 42, and the icon 43 corresponding to the individual deletion item of the individual menu is also referred to as an individual deletion icon 43.

  In the non-display setting icon 40, the individual rotation setting icon 41, the individual display icon 42, and the individual deletion icon 43, character strings indicating processes that can be selected by the icons 40 to 43 are displayed.

  When the non-display setting icon 40 is selected on the menu composite image 25 by the user via the operation input unit 7, the control unit 2 shifts to a non-display setting mode in which the still image SG is individually set to non-display.

  In this state, when one still image SG is arbitrarily selected as a non-display target on the menu composite image 25 by the user via the operation input unit 7, the control unit 2 selects the selected still image SG as the second display target. Surround with a color frame.

  Further, the control unit 2 displays a check box in the upper right corner of the selected still image SG, and puts a check mark in the check box to indicate that the still image SG is selected as a non-display target. indicate.

  In this state, the control unit 2 updates the content of the corresponding display presence / absence setting information in the display state setting table DT when the user commands the non-display setting to the still image SG via the operation input unit 7. Thereby, the control part 2 sets the still image SG selected arbitrarily arbitrarily to non-display.

  Incidentally, when the same still image SG is selected again after the desired still image SG is set to non-display, the control unit 2 reproduces the non-display setting content in the check box of the still image SG. A check mark is displayed on.

  Then, even after setting the still image SG to be non-displayed, the control unit 2 deletes the check mark and cancels the non-display setting when the check box is operated while the still image SG is selected again. be able to.

  Therefore, the control unit 2 can not display the still image SG requested not to be displayed, and can easily cope with the request even if it is requested to be displayed later. Can be displayed.

  In addition, when the individual rotation setting icon 41 is selected on the menu composite image 25 by the user via the operation input unit 7 in the partial image rotation display setting mode, the control unit 2 individually rotates and displays the still image SG. It shifts to the individual rotation display setting mode that is set so as to do.

  In this state, when one still image SG is arbitrarily selected as a rotation target on the menu composite image 25 by the user via the operation input unit 7, the control unit 2 selects the selected still image SG as a second object. Surround with a color frame.

  Further, the control unit 2 displays a check box in the upper right corner of the selected still image SG, and displays a check mark in the check box to indicate that the still image SG is selected as a rotation target. To do.

  In this state, when the control unit 2 arbitrarily designates a specified rotation angle with respect to the still image SG via the operation input unit 7 and the user is instructed to set the rotation display of the still image SG in this state, the display state The rotation setting information is added to the setting table DT in association with the file name.

  However, when the designated rotation angle of the still image SG is different from the correction rotation angle in the right direction indicated by the corresponding rotation angle information, the control unit 2 performs a new rotation indicating the designated rotation angle with respect to the display state setting table DT. Add angle information in association with the file name.

  In this case, the control unit 2 adds rotation setting information indicating rotation angle information used for rotation of the still image SG in association with the file name to the display state setting table DT. Accordingly, the control unit 2 sets the still image SG that is arbitrarily selected to be rotated and displayed at the designated rotation angle.

  However, even if one still image SG is arbitrarily selected by the user, the control unit 2 displays the still image SG in the screen downward direction when the setting of the rotation display is instructed without designating the designated rotation angle. It is set so that it is rotated and displayed so that the display orientation faces the lower end.

  In other words, the control unit 2 designates the user only when one arbitrarily selected still image SG is set so as to be rotated and displayed so that the downward direction of the image is the downward direction of the screen. Even if the rotation display is instructed without specifying the rotation angle, it can be realized.

  Incidentally, when the rotation display of one still image SG is individually set, the control unit 2 performs rotation processing on the still image data SD of the still image SG according to the actually specified designated rotation angle or rotation angle information. .

  Thereby, the control part 2 can rotate and display one still image SG arbitrarily selected on the menu composite image 25, and can confirm the display state of the still image SG.

  Further, when the individual display icon 42 is selected on the menu composite image 25 by the user via the operation input unit 7, the control unit 2 shifts to an individual display mode in which the still images SG are individually displayed.

  In this state, when one still image SG is arbitrarily selected as an individual display target on the menu composite image 25 by the user via the operation input unit 7, the control unit 2 selects the selected still image SG as the second display target. Surround with a color frame.

  Further, the control unit 2 displays a check box at the upper right corner in the selected still image SG, and puts a check mark in the check box to indicate that the still image SG is selected as an individual display target. indicate.

  When the start of display is instructed by the user via the operation input unit 7, the control unit 2 enlarges, for example, one still image SG arbitrarily selected as the individual display target on the menu composite image 25. indicate.

  In this way, the control unit 2 can finely confirm the content of one still image SG that is arbitrarily selected on the menu composite image 25.

  Furthermore, when the individual deletion icon 43 is selected on the menu composite image 25 via the operation input unit 7 by the user, the control unit 2 shifts to an individual deletion mode in which the still images SG are individually deleted.

  In this state, when one still image SG is arbitrarily selected as a deletion target on the menu composite image 25 by the user via the operation input unit 7, the control unit 2 selects the selected still image SG as the second target. Surround with a color frame.

  Further, the control unit 2 displays a check box in the upper right corner of the selected still image SG, and displays a check mark in the check box to indicate that the still image SG is selected as a deletion target. To do.

  In this state, when the user instructs to delete the still image SG via the operation input unit 7, the control unit 2 deletes the still image SG on the menu composite image 25.

  Further, the control unit 2 deletes all information corresponding to the still image SG to be deleted from the display state setting table DT.

  Further, the control unit 2 also deletes the image file GF corresponding to the still image SG to be deleted from the storage unit 3. Thereby, the control part 2 can delete one still image SG selected arbitrarily.

  Incidentally, when the group menu selection button 37 is selected on the menu composite image 25 by the user via the operation input unit 7, the control unit 2 changes various icons for group menus in place of various icons for individual menus in the menu image 26. Display icon.

  By the way, when the display mode switching icon 28 is selected on the menu composite image 25 by the user via the operation input unit 7, the control unit 2 can arbitrarily select a single column display, a list display, or a group display as the display mode. A pull-down menu (not shown) is displayed.

  When the user selects, for example, a list display on the pull-down menu via the operation input unit 7 by the user, the control unit 2 displays the menu shown in FIG. A composite image 45 is displayed.

  In this case, the menu composite image 45 is displayed with the menu image 26 superimposed on the right end of the list display image 21 and the selection image 27 superimposed on the left side of the lower end of the list display image 21.

  When the menu composite image 45 is displayed on the display screen 10 </ b> A, the control unit 2 causes the user to perform the same operation as described above, and executes the same process as described above according to the operation.

  Further, the control unit 2 can arbitrarily select a single line display, a list display, or a group display as a display form even if the display form switching icon 28 is selected on the menu composite images 25 and 45 via the operation input unit 7 by the user. Display a possible pull-down menu (not shown).

  When the user selects, for example, display by group on the pull-down menu via the operation input unit 7 by the user, the control unit 2 is shown in FIG. 13 in which the same reference numerals are given to the corresponding portions of FIG. 10 on the display screen 10A. A menu composite image 46 is displayed.

  In this case, the menu composite image 46 has a menu image 47 superimposed on the right end of the group-specific display image 22 and a selection image 27 superimposed on the left side of the lower end of the group-specific display image 22. Yes.

  Further, the menu image 47 is provided with an icon (hereinafter also referred to as a management form change icon) 48 corresponding to the management form change item of the option menu, instead of the sort icon 30 described above.

  When the menu composite image 46 is displayed on the display screen 10A, the control unit 2 causes the user to operate in the same manner as described above except for the sort processing, and executes the same processing as the processing described above according to the operation. .

  However, when the management mode change icon 48 is selected on the menu composite image 46 by the user via the operation input unit 7, the control unit 2 shifts to a management mode change mode for changing the management mode of the image file GF.

  At this time, the control unit 2 associates the plurality of image files GF with different folders for each group so that the image files GF can be managed for each group using these folders.

  In this way, the control unit 2 can manage a plurality of image files GF in units of groups in which still images with similar patterns are grouped.

  Incidentally, when the user instructs to delete the menu via the operation input unit 7 in a state where the menu composite image 25 is displayed on the display screen 10A, the control unit 2 displays the original line on the display screen 10A accordingly. A display image 20 is displayed.

  However, when the controller 2 is instructed to delete the menu while the group or still image SG is selected on the menu composite image 25, the group 2 or still image SG is displayed on the display screen 10A as shown in FIG. A one-line display image 20A is displayed with the selection status clearly indicated.

  Similarly, the control unit 2 can change the display on the display screen 10 </ b> A from the menu composite images 45 and 46 to the original list display image 21 and the group-specific display image 22.

  Also at this time, the control unit 2 appropriately displays the list display image 21A and the group-specific display image 22A as shown in FIGS. 15 and 16 on the display screen 10A.

  In this way, the control unit 2 sets the display state desired for the plurality of still images SG such as rotation, display, non-display, and deletion to be reflected in the contents of the display state setting table DT.

  When the user requests the list display of the still images SG via the operation input unit 7 after the display state setting processing for the plurality of still images SG is completed, the control unit 2 stores all of the images from the storage unit 3. The still image data SD in the image file GF is read out. At this time, the control unit 2 also reads the display state setting table DT from the storage unit 3.

  Then, the control unit 2 generates list display image data using a plurality of still image data SD based on the display state setting table DT, and sends the generated list display image data to the display unit 10.

  Thus, the control unit 2 displays a plurality of still images SG based on the plurality of still image data SD in a matrix of a plurality of rows and a plurality of columns on the display screen 10A based on the list display image data.

  Actually, if the control unit 2 has not set any display state for the plurality of still images SG, the plurality of still images SG are displayed as a list display image 50 on the display screen 10A as shown in FIG. Each is displayed in the reference display direction regardless of the downward direction of the image.

  On the other hand, when the control unit 2 is set to display the still image SG as a display state by rotating all or in units of groups, the control unit 2 displays a list display image 51 as shown in FIG. 18 on the display screen 10A.

  In this case, the control unit 2 displays all or group-unit still images SG10 and SG11 as the list display image 51 on the display screen 10A in a display direction in which the image lower direction coincides with the direction from the screen upper end 10AT toward the screen lower end 10AU. Rotate and display.

  Further, when the control unit 2 is set to display the still image SG so as to be rotated in group units or individually as the display state, the control unit 2 displays a list display image 52 as shown in FIG. 19 on the display screen 10A.

  That is, the control unit 2 displays, as the list display image 52 on the display screen 10A, for example, one still image SG12 in the group in a display orientation in which the image lower direction coincides with the direction from the screen left end 10AL toward the screen right end 10AR. Rotate and display.

  Still image 2 is displayed in such a list display image 52, for example, with respect to the other still images SG13 to SG15 in the group, in a display orientation in which the image lower direction coincides with the direction from the screen upper end 10AT to the screen lower end 10AU. To do.

  Further, when the control unit 2 is set to display one still image SG in the group so as to be rotated and displayed at a specified rotation angle, and to display a plurality of other still images SG to be rotated and displayed at a detected rotation angle as the display state. A list display image 53 as shown in FIG. 20 is displayed on the display screen 10A.

  In this case, the control unit 2 displays the list display image 53 on the display screen 10A as, for example, a plurality of still images SG12 to SG15 in the group in the direction in which the image lower direction is from the desired screen left end 10AL toward the screen right end 10AR. Rotate the display to the display orientation you want.

  Furthermore, the control unit 2 sets the display state so that one still image SG in the group is displayed alone, and sets the other plurality of still images SG to non-display. A list display image 54 as shown is displayed.

  In this case, the control unit 2 displays, for example, only one of the plurality of still images SG12 to SG15 in the group as the list display image 54 on the display screen 10A.

  In the case of this embodiment, when new recognition reference image data is generated for the image recognition processing, the control unit 2 stores the new recognition reference image data in the storage unit 3 and the subsequent image. Can be used for recognition processing.

  Further, when a new processing method is developed for the image recognition process or the similar image search process, the control unit 2 installs a program for executing the image recognition process or the similar image search process by the new processing method. Thus, it can be used for subsequent image recognition processing and similar image search processing.

  When the control unit 2 requests the setting of the display state for the still image SG for the first time by the user via the operation input unit 7, all the still image data stored as the image file GF in the storage unit 3 at that time. An image recognition process (or similar image search process) is executed for SD.

  In addition, when the user requests the display state setting again through the operation input unit 7 (that is, after the second time, such as the second time, the third time,...), The control unit 2 responds to the user setting. Image recognition processing (or similar image search processing) is executed.

  That is, when the user requests the setting of the display state again via the operation input unit 7, the control unit 2 performs image processing for all the still image data SD stored as the image file GF in the storage unit 3 at that time. The recognition process (or similar image search process) can be executed again.

  In this case, the control unit 2 can recognize a plurality of still images SG by reflecting new recognition reference image data and a new processing method in the image recognition process and the similar image search process, and classify them into groups.

  Further, when the setting of the display state is requested again by the user via the operation input unit 7, the control unit 2 performs image recognition processing (or similar image search) only for still image data SD newly stored after the previous setting. Processing) can also be executed. In this case, the control unit 2 can greatly reduce the processing load of the image recognition process and the similar image search process.

(1-2) Display State Setting Process Next, the display state setting process procedure RT1 executed by the control unit 2 of the image display device 1 will be described using the flowchart shown in FIG.

  When the user is requested to set the display state for the still image SG via the operation input unit 7, the control unit 2 performs the display state setting process shown in FIG. 22 according to the display state setting program recorded in advance in the storage unit 3. Procedure RT1 is started.

  When the display state setting processing procedure RT1 is started, the control unit 2 reads a plurality of image files GF from the storage unit 3 in step SP1, temporarily records them in the RAM 6, and moves to the next step SP2.

  In step SP2, the control unit 2 checks the contents of the header data HD included in the image file GF, appropriately generates rotation information, and temporarily records the rotation information in the RAM 6 in association with the image file GF. Next step SP3 is entered.

  In step SP3, the control unit 2 reads a plurality of still image data SD included in the plurality of image files GF from the RAM 6, and proceeds to the next step SP4.

  In step SP4, the control unit 2 sequentially performs a correction process on the plurality of still image data SD, and proceeds to the next step SP5.

  In step SP5, the control unit 2 executes image recognition processing by sequentially using a plurality of still image data, recognizes what kind of object each of the plurality of still images SG is drawn, and all the images. When the recognition process ends, the process proceeds to the next step SP6.

  In step SP6, the control unit 2 determines whether there is still image data SD of the still image SG that could not be recognized by the image recognition process.

  As a result, when there is still image data SD of the still image SG that could not be recognized by the image recognition process, the control unit 2 proceeds to the next step SP7.

  Further, if there is no still image data SD of the still image SG that could not be recognized by the image recognition process, the control unit 2 does not execute the process of the next step SP7 and proceeds to the next step SP8.

  In step SP7, the control unit 2 performs similar image search processing using the still image data SD of the still image SG that could not be recognized by the image recognition processing and the still image data SD of the still image SG that has already been recognized. Execute.

  Thereby, the control unit 2 searches for a recognized still image SG similar to the still image SG that could not be recognized by the image recognition process. And the control part 2 makes the said recognition result of the recognized still image SG searched as the recognition result of the still image SG which could not be recognized by the image recognition process, and when all the similar image search processes are complete | finished. The process proceeds to the next step SP8.

  In step SP8, the control unit 2 classifies the plurality of still image data SD into a plurality of groups based on the recognition result of the still image SG, and proceeds to the next step SP9.

  In step SP9, the control unit 2 performs the correction rotation detected to rotate the still image SG so that the lower direction of the image is directed to the lower end of the screen in the classification result of the plurality of still image data SD and the image recognition process and the similar image search process. A display state setting table DT is generated using an angle or the like. And the control part 2 memorize | stores the display state setting table DT in the memory | storage part 3, and moves to following step SP10.

  In step SP10, the control unit 2 displays a plurality of still images SG based on the plurality of still image data SD on the display screen 10A of the display unit 10. In this state, the control unit 2 sets a display state such as rotational display, single display, non-display, and deletion of one or a plurality of still images SG according to a user operation, and then moves to the next step SP11 to display The state setting process procedure RT1 is terminated.

(1-3) Operation and Effect of Embodiment In the above configuration, the image display device 1 captures a plurality of still image data SD from the outside and stores them in the storage unit 3.

  When the image display device 1 is requested to set the display state of the plurality of still images SG based on the plurality of still image data SD, the image display device 1 sequentially recognizes what the plurality of still images SG are. To do.

  Further, the image display device 1 can correct the display orientation of the plurality of still images SG at this time so that the downward direction of the image is directed to the lower end of the screen from the reference display orientation according to the vertically and horizontally defined images. Detect the rotation angle.

  Further, the image display device 1 classifies the plurality of still image data SD into a plurality of groups based on the recognition result of the still image SG.

  Then, the image display device 1 displays each of the plurality of still images SG based on the plurality of still image data SD in the reference display direction on the display screen 10A of the display unit 10.

  In this state, when the designated rotation angle from the reference display direction is designated for one still image SG selected from a plurality of still images SG of an arbitrary group, the image display device 1 is selected. It is set so that the still image SG is rotated to the designated rotation angle and displayed.

  Further, the image display device 1 selects the still image SG other than the selected still image SG of the group based on the designated rotation angle and the corrected rotation angle of the plurality of still images SG of the group. It is set to rotate and display the still image SG so that the lower direction of each image is in the same direction as when the still image SG is rotated to the specified rotation angle.

  Accordingly, the image display device 1 can select one still image SG and designate a designated rotation angle without selecting and rotating a plurality of still images SG in the group one by one. A plurality of still images SG can be set to be rotated and displayed so that their display directions are aligned.

  According to the above configuration, when the image display device 1 recognizes a plurality of still images SG, the plurality of still images SG can be corrected in a display direction in which the image lower direction is directed to the lower end of the screen from the reference display direction. While detecting the rotation angle, the plurality of still images SG are classified into a plurality of groups based on the recognition result, and the plurality of still images SG for each group are displayed in the reference display direction on the display screen 10A. When a designated rotation angle is designated for one still image SG of the group, the selected still image SG is set to be rotated and displayed up to the designated rotation angle, and the designated rotation angle and a plurality of groups Based on the corrected rotation angle of the still image SG, the other still images SG of the group are rotated when the selected still image SG is rotated to the designated rotation angle and below each other image. There were so set as to display the rotated such that the display direction facing the same direction. As a result, the image display apparatus 1 rotates the plurality of still images SG so as to align the display directions only by selecting one still image SG from among the plurality of still images SG in the group and designating the designated rotation angle. Can be set to be displayed. Therefore, the image display device 1 can significantly improve operability.

  Further, the image display apparatus 1 classifies the plurality of still images SG into groups so that the still images SG on which the same objects are drawn are grouped based on the recognition results of the objects drawn on these images. A plurality of still images SG are collectively displayed for each group.

  Accordingly, the image display apparatus 1 is set to rotate and display a plurality of other still images SG together with the one still image SG by designating a designated rotation angle with respect to one still image SG. It is possible to easily confirm what still image SG is to be displayed together with one still image SG.

  Further, the image display device 1 does not allow a single still image SG to be selected or a designated rotation angle to be designated when a plurality of still images SG in an arbitrary group are displayed in a display orientation in which the lower direction of the image faces the lower end of the screen. However, the plurality of still images SG of these groups are set to be rotated and displayed.

  Therefore, the image display device 1 simplifies the operation for setting the rotation display of the plurality of still images SG when the plurality of still images SG are displayed in the display orientation in which the lower direction of the images is directed to the lower end of the screen. The operability can be further improved.

  Further, the image display apparatus 1 individually selects a still image SG to be set to non-display from a plurality of still images SG of the group, and sets the selected still image SG to non-display.

  As a result, the image display apparatus 1 can easily prevent the still image SG from being displayed even when there is a still image SG that is desired not to be displayed in the group. Display can be avoided in advance.
