(First embodiment)
FIG. 1 is a block diagram showing the configuration of a digital camera to which the present invention is applied. The digital camera 1 according to the present embodiment is a lens-integrated digital camera, and an image of a subject image formed by a lens (imaging optical system) (not shown) is captured by the image sensor 103, whereby image data of the subject image is obtained. It has a function to create.

  The digital camera 1 includes a CPU 101 including a microprocessor and its peripheral circuits. The CPU 101 controls each unit of the digital camera 1 by reading and executing a predetermined control program from a storage medium (not shown). The CPU 101 is connected to a lens driving circuit 102, an image sensor 103, a power controller 104, a card controller 105, a USB controller 106, a WiFi driver 107, an I / F driver 108, a memory 109, and an LCD driver 110. Hereinafter, each of these units will be described in order.

  The lens driving circuit 102 drives a focusing lens included in the imaging optical system in the optical axis direction by an actuator such as a stepping motor. The CPU 101 adjusts the imaging position of the subject image by causing the lens driving circuit 102 to drive a focusing lens.

  The image sensor 103 is an image sensor such as a CCD or a CMOS. The image sensor 103 captures a subject image formed on the imaging surface and outputs a photoelectric conversion signal (imaging signal) corresponding to the brightness of the subject image. Since R (red), G (green), and B (blue) color filters are provided on the imaging surface of the imaging element 103 so as to correspond to the pixel positions, imaging signals output from the imaging element 103 are provided. Has color information defined by the RGB color system.

  An image pickup signal output from the image pickup element 103 is converted into digital data (image data) by an A / D converter (not shown) and then input to an image processing circuit (not shown), and various kinds of operations such as contour compensation and gamma correction are performed. Image processing is performed. The CPU 101 receives image data that has been subjected to these image processes.

  The image sensor 103 and its peripheral circuits (image processing circuit and the like) can output a so-called through image in addition to normal still image data (captured image). This is image data that is repeatedly imaged by the image sensor 103 and is output at a frame rate of 60 frames per second, for example. In order to maintain this frame rate, each frame constituting the through image has fewer pixels than normal still image data, or some image processing is omitted.

  The power controller 104 controls the operating power supplied to each part of the digital camera 1. The operating power of each unit is supplied from a battery 111 connected to the power supply controller 104. The card controller 105 controls reading / writing of the memory card 2 inserted in the card slot 112. The memory card 2 is a portable storage medium and is configured to be detachable from the card slot 112.

  The USB controller 106 performs data communication based on a well-known USB standard with an external device 3 (for example, a digital camera or a mobile phone) connected to the USB connector 113. For example, the CPU 101 can exchange image data between the memory card 2 and the external device 3 by data communication via the USB controller 106.

  The WiFi driver 107 performs wireless data communication with an external device by driving a WiFi transmission / reception unit 114 including a wireless antenna and the like. The CPU 101 can exchange image data with, for example, an external device by data communication via the WiFi driver 107, similarly to data communication via the USB controller 106.

  The I / F driver 108 detects an operation on the operation switch 115 such as a keypad or a push button, and outputs an operation signal corresponding to the operation to the CPU 101. The memory 109 is a non-volatile storage medium such as a flash memory. The digital camera 1 stores various information necessary for realizing an object function described later in the memory 109.

  The LCD driver 110 drives a display 116 having a display screen such as a liquid crystal panel, and displays characters, images, and the like on the display screen. For example, when the CPU 101 outputs an image signal to the LCD driver 110, an image corresponding to the image signal is displayed on the display screen of the display 116.

  In the digital camera 1 of the present embodiment, a photographed image is associated with a predetermined object recognized by analyzing the through image (for example, various objects recognizable from the through image, such as dolls, figurines, flowers, and paintings) and managed. Functions (hereinafter referred to as object functions) are mounted. When a certain captured image is associated with a specific object, the captured image can be browsed only when the similar object is recognized again. According to this object function, it becomes possible to manage a photographed image as if it was stored in a specific article.

  The object function includes two functions: a function for storing information specifying an object and a captured image in association with each other (hereinafter referred to as a storage function), and a function for reading a captured image associated with the object (hereinafter referred to as a read function). It consists of two functions.

  FIG. 2A is a schematic diagram showing an outline of the storage function. When the user 4 puts an arbitrary object 5 (the stuffed animal is an object in FIG. 2A as an example) within the angle of view of the digital camera 1 and instructs the object to store (associate) the image data 6, the digital camera The image data stored in the first memory 109 is associated with the object 5.

  FIG. 2B is a schematic diagram showing an outline of the reading function. After the image data 6 is stored in (associated with) the object 5, when the digital camera 1 is set to a predetermined mode and the object 5 is held within the angle of view, the image 116 of the object 5 is displayed on the display 116 of the digital camera 1. 7, a marker 8 indicating that the image data 6 is stored in the object is displayed. Here, when the user performs a predetermined operation, the image data 6 can be reproduced and viewed.

  As described above, when the storage function and the reading function are used, the digital camera 1 behaves as if image data is stored in the object 5. Through these functions, the user can manage each image data as if storing the image data in an actual article.

  FIG. 3 is a diagram schematically showing an area on the memory 109 used for the object function. The CPU 101 provides two types of areas, an image data area 11 and a management area 12, in the memory 109, and uses these areas for object functions. In the image data area 11, image data 21 of a captured subject image and an image ID 22 that is a unique identifier for each image data 21 (for example, an integer different for each image data 21) are stored in association with each other. The management area 12 is an area for storing information (information accompanying each image data 21) for managing each image data 21 stored in the image data area 11, and includes an image index 23 and an object described later. An index 24 is stored.

  The procedure for taking a still image by the digital camera 1 is the same as that of a general digital camera. When shooting a still image, the user sets a still image shooting mode in the digital camera 1 using the operation switch 115 or the like. Thereafter, the image forming optical system is directed toward the subject, and the release switch included in the operation switch 115 is pressed, so that the digital camera 1 captures the subject image. The CPU 101 controls the image sensor 103 in response to pressing of the release switch, and causes the image sensor 103 to capture the subject image formed by the imaging optical system. Thereby, the image data 21 based on the imaging signal output from the imaging element 103 is input to the CPU 101. The CPU 101 assigns an image ID 22 to the image data 21 and stores it in the image data area 11 shown in FIG. The CPU 101 further stores information related to the image data 21 in an image index 23 described below.

  FIG. 4 is a diagram showing the configuration of the image index 23. In the image index 23, for each image data 21 stored in the image data area 11, an image ID 22, registration presence / absence information 25, and an object ID 26 of the image data 21 are stored in association with each other.

  The registration presence / absence information 25 is information indicating whether or not the image data 21 is associated with a specific object. When the image data 21 is associated with a specific object, the registration presence / absence information 25 is “1”. Conversely, when the image data 21 is not associated with a specific object, the registration presence / absence information 25 is “0”.

  The object ID 26 is information representing an object associated with the image data 21. The object ID 26 is stored in the image index 23 only when the registration presence / absence information 25 is “1”. That is, when the registration presence / absence information 25 is “0”, the object ID 26 is not stored in the image data 21.

  When new image data 21 is stored in the image data area 11 by shooting, the CPU 101 stores the image ID 22 of the image data 21 and the registration presence / absence information 25 of “0” in the image index 23. . At this time, the object ID 26 is not stored.

  The user can reproduce / view the image data 21 whose registration presence / absence information 25 is “0” without any limitation. For example, when the digital camera 1 is set to the reproduction mode by the operation switch 115 or the like, the CPU 101 reads the image ID 22 of each image data 21 whose registration presence / absence information 25 is “0” from the image index 23. Then, each image data 21 assigned with the image ID 22 is read from the image data area 11 and a list of thumbnail images of the image data 21 is displayed on the display screen of the display 116. The thumbnail image may be stored in advance in the memory 109 by reducing the image data 21 or may be created by reducing the image data 21 at the time of display. When the user selects any thumbnail image with the operation switch 115, the CPU 101 displays the image data 21 corresponding to the thumbnail image on the display screen of the display 116.

  Next, a specific operation of the storage function will be described. FIG. 5 is a flowchart of the image data storage process. When the user sets the digital camera 1 to the image storage mode using the operation switch 115 or the like, the control program executed by the CPU 101 starts executing the processing shown in FIG.

  First, in step S100, the CPU 101 displays a list of thumbnail images as in the playback mode. That is, a list of thumbnail images of the image data 21 whose registration presence / absence information 25 is “0” is displayed on the display screen of the display 116. In step S110, the user refers to the display screen and selects at least one image data 21 to be associated with a specific object by operating the operation switch 115 (performs a selection operation). As a result, the selection operation of the image data 21 is input from the operation switch 115 to the CPU 101. Hereinafter, the image data 21 selected here is referred to as a “storage target image”.

  In step S <b> 120, the CPU 101 starts displaying a through image on the display screen of the display 116. In step S <b> 130, the user captures an object that the user wants to store the storage target image (to associate with the storage target image) within the angle of view, and presses the release switch. As a result, a release switch pressing operation is input from the operation switch 115 to the CPU 101. In step S140, the CPU 101 analyzes the through image at the time of pressing with a known algorithm (for example, template matching or the like) in accordance with the input of the release switch pressing operation, and recognizes an object included in the through image.

  Thereafter, in step S150, the CPU 101 displays the through image at the time of pressing on the display screen, and highlights the recognized object by a method such as surrounding a section corresponding to the object with a highlight color such as red. Then, the user is asked to confirm that the storage target image is stored (associated) with the object. For example, a confirmation message such as "Do you want to store image data in this object?"

  When the CPU 101 recognizes a plurality of objects, the CPU 101 causes the user to select which of these objects is to be stored as image data before executing step S150. The user selects any one object from a plurality of objects using the operation switch 115 or the like. The CPU 101 executes the process of step S150 for the object selected here.

  In step S160, it is determined whether the input from the operation switch 115 by the user is an input for determining storage or an input for canceling storage. If the user cancels the storage of the image data, the process returns to step S130, and the CPU 101 resumes the display of the through image again. On the other hand, if the user has selected to store image data, the process proceeds to step S170. In step S170, the CPU 101 updates the object index 24 and registers the object recognized in step S140.

  FIG. 6 is a diagram showing the configuration of the object index 24. In the object index 24, an object ID 26 that is an identifier unique to each object (for example, an integer unique to each object) and object specifying information 27 that is information for specifying the object are stored in association with each other. .

  The object specifying information 27 is data in a format corresponding to an algorithm for recognizing an object from a through image. For example, when an object is recognized by a technique such as feature point extraction, the object specifying information 27 is information representing the feature point of the object. Further, when an object is recognized by a technique such as pattern matching, the image data of the object cut out from the through image, its feature amount, and the like.

  In step S170, the CPU 101 assigns a unique object ID 26 to the recognized object, and stores it in the object index 24 together with the object specifying information 27 of the object. In step S180, the CPU 101 updates the image index 23 and stores (associates) the storage target image with the recognized object. Here, the CPU 101 updates the registration presence / absence information 25 of the image to be stored in the image index 23 to “1” and the object ID 26 to the object ID 26 of the recognized object. That is, in step S180, the CPU 101 rewrites the registration presence / absence information 25 and the object ID 26 of the image index 23 corresponding to the image ID 22 of the image to be stored.

  It should be noted that an animation in which the storage target image flows into the object on the through image may be displayed in order to visually express that the storage target image is stored in the recognized object.

  Next, a specific operation of the reading function will be described. FIG. 7 is a flowchart of the image data reading process. When the user sets the digital camera 1 to the image reading mode with the operation switch 115 or the like, the control program executed by the CPU 101 starts executing the processing shown in FIG.

  First, in step S <b> 200, the CPU 101 starts displaying a through image on the display screen of the display 116. Hereinafter, until the digital camera 1 is set to a mode other than the image reading mode, the CPU 101 repeatedly executes the processes of steps S210 to S260 while capturing and displaying a through image.

  In step S210, the CPU 101 analyzes the latest through image using a known algorithm, and recognizes an object included in the through image. In step S220, the CPU 101 checks the object index 24 and the image index 23 for each object recognized in step S210, and determines whether the image data 21 is stored (associated) with the object. For example, the object ID 26 corresponding to the object specifying information 27 of the recognized object is searched from the object index 24, and the object ID 26 is searched from the image index 23 to find the image ID 22 whose registration presence / absence information 25 is “1”.

  If the object identification information 27 of the recognized object is not stored in the object index 24, or if the object ID 26 is not stored in the image index 23, no image data 21 is stored in the object. (Not associated). In this case, the process proceeds to step S240. On the other hand, if at least one image data 21 is stored (associated) with the recognized object, the process proceeds to step S230.

  In step S230, the CPU 101 highlights an object in which at least one image data 21 is stored (associated). For example, on the display screen of the display 116, an icon, a marker, or the like indicating that the image data 21 is stored is displayed superimposed on the object. If a plurality of objects are recognized, the CPU 101 displays icons, markers, etc. for each of them.

  The user can select one of the objects highlighted in step S230 by operating the operation switch 115 or the like. In step S240, the CPU 101 determines whether or not this selection operation has been input from the operation switch 115. If an object selection operation has not been input, the process proceeds to step S260. On the other hand, if any object has been selected, the process advances to step S250, and the CPU 101 displays a list of thumbnail images of the image data 21 stored (associated) with the selected object.

  When there is only one image data 21 stored (associated) with the object, the image data 21 itself may be displayed on the display screen of the display 116 instead of the thumbnail image.

  The user can perform, for example, an operation of taking out the image from the object (releasing the association with the object) and other normal image operations (for example, displaying or deleting the image data 21) on the displayed thumbnail image. it can. In the flowchart of FIG. 7, processing related to these operations is omitted.

  In step S260, the CPU 101 determines whether or not the image reading mode has ended. When a mode other than the image reading mode is set by the user in the digital camera 1, the image reading mode ends, and the process shown in FIG. 7 ends. On the other hand, if the image reading mode is set, the process returns to step S210, and the processing from step S210 is repeatedly executed.

  As in the case of storing (associating) image data with an object, when image data is read from the object, a state in which the image data is extracted from the object may be displayed by animation or the like. By performing such display, it becomes easy to visually understand that image data is stored in the object.

According to the digital camera according to the first embodiment described above, the following operational effects can be obtained.
(1) The memory 109 stores image data created from the image signal output from the image sensor 103. The CPU 101 analyzes the imaging signal output from the imaging element 103 to recognize a predetermined object, associates the object and image data, and stores them in the memory 109. Since it did in this way, image data can be classified as desired and managed intuitively.

(2) The memory 109 stores a plurality of image data, and the CPU 101 stores the plurality of image data in association with the recognized object in the memory 109. Since it did in this way, many image data can be managed efficiently.

(3) The CPU 101 can store the image data stored in the memory 109 in the memory 109 in association with any of a plurality of recognized objects. As described above, when there are a large number of recognizable objects, the user can freely select an object to be associated with the image data, and the image data can be managed flexibly.

(4) The CPU 101 displays a through image on the display screen based on the imaging signal output from the imaging element 103 and recognizes the object by analyzing the imaging signal. When the object is recognized, the image data associated with the object is read from the memory 109 so that the user can perform various operations. Since it did in this way, image data can be classified as desired and managed intuitively.

(5) The memory 109 stores different image data in association with each of the plurality of objects. In other words, certain image data is associated with only one of the plurality of objects. Since it did in this way, intuitive management can be performed as if image data was stored in a specific object.

(6) The display 116 displays the emphasized contour line of the object recognized by the CPU 101 and the image data associated with the object read by the CPU 101 on the display screen so as to be superimposed on the subject image. . Since this is done, it is possible to easily grasp which image data is stored (associated) in which object.

(Second Embodiment)
In the first embodiment described above, image data once stored (associated) in some object cannot be reproduced / viewed unless an object selection operation is performed in the image reading mode. Therefore, for example, if the user forgets an object that stores (associates) image data or loses the object, the image data cannot be reproduced.

  Therefore, in the digital camera of this embodiment, in addition to the functions described in the first embodiment, an object management function for managing image data stored (associated) in a specific object is provided. The object management function will be described in detail below. In the following description, the same components as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and description thereof is omitted.

  FIG. 8 is a flowchart of the object management process. When the user sets the digital camera 1 to the object management mode using the operation switch 115 or the like, the CPU 101 starts executing the processing shown in FIG.

  First, in step S <b> 300, the CPU 101 specifies the image ID 22 whose registration presence / absence information 25 is “1” from the image index 23 and displays a list of thumbnail images of the corresponding image data 21. That is, thumbnail images of the image data 21 stored (associated) in some object are displayed as a list. From the displayed thumbnail image, the user selects a thumbnail image of the image data 21 whose storage state in the object is to be canceled (association is to be canceled). Hereinafter, the image data 21 selected here is referred to as a “storage release target image”.

  In step S <b> 310, the CPU 101 receives an operation for selecting a storage release target image input by the user from the operation switch 115. In step S320, the CPU 101 updates the image index 23, sets the registration release information 25 of the storage release target image to “0”, and deletes the object ID 26. Through the above processing, the storage release target image is released from the storage state in the object, and can be reproduced and viewed as usual.

According to the digital camera according to the second embodiment described above, the following operational effects can be obtained.
(1) Image data associated with a specific object can be returned to an unassociated state by object management processing. Thereby, even when the object is lost or forgotten, the image data associated with the object can be restored.

  The following modifications are also within the scope of the present invention, and one or a plurality of modifications can be combined with the above-described embodiment.

(Modification 1)
Image data stored (associated) in a specific object by a certain digital camera may be handled by another digital camera. That is, the image data stored (associated) in a specific object may be shared with other devices.

  In this case, if the image data 21, the image index 23, the object index 24, etc. are stored in the memory card 2 which is a portable storage medium instead of the memory 109 built in the digital camera 1, the memory card 2 is stored in another memory card 2. The image data can be moved by attaching it to the device. In addition, the image data can be shared by transmitting / receiving these data by wireless communication by the WiFi transmitting / receiving unit 114 or by transmitting / receiving these data to / from the external device 3 connected to the USB connector 113. it can.

(Modification 2)
An object may be recognized in real time for a through image. In this case, the presence or absence of image data associated with each recognized object is checked, and if such image data exists, the image data is stored (associated) with that object. An icon, a marker, or the like to be displayed may be superimposed on the object. Alternatively, thumbnail images of image data stored in the object may be displayed in a superimposed manner. Also, when an object in which image data is stored (associated) is recognized, thumbnail images of the image data stored in (associated with) the object are displayed in a list immediately. It is also possible to configure the digital camera 1.

(Modification 3)
The object recognition method is not limited to that described in the above-described embodiment. For example, when recognizing an object, instead of analyzing a through image, the still image may be analyzed after normal still image shooting is performed. In this case, since the number of pixels of the image to be analyzed increases, more precise analysis can be performed. Instead, the time required for analysis increases. Further, the digital camera 1 may be configured to detect the depth of the object, and the object may be recognized in consideration of the depth. With this configuration, for example, by preparing a picture of an object, it is possible to prevent image data stored in (associated with) the object from being read out.

  Further, recognition may be performed in consideration of the movement of the object. For example, the digital camera 1 can be configured such that information on objects over a plurality of frames is stored, and image data can be read when the same movement of the same object is recognized. In this case, if the movements of the objects do not match at the time of reading, a stored movement hint may be presented to the user.

  In addition, the user may arbitrarily specify the object recognition accuracy. For example, when reading certain image data, the object is recognized so that the difference in color tone is ignored if the shape is the same. When storing another image data, the shape and the color tone are exactly the same. Otherwise, recognition may be performed so as not to regard the same object. Such designation of recognition accuracy is performed when the image data is stored, and is stored in the image index 23 and the object index 24. By making it possible to specify the recognition accuracy in this way, it becomes possible to manage image data more flexibly.

(Modification 4)
Data other than image data may be stored (associated) in the object. For example, data such as document data, audio data, and video data can be stored (associated) in an object. In this case, in the image readout mode, when an object in which audio data is stored (associated) is recognized, the audio data is reproduced while the through image is displayed, or in the case of video data. The video data can be reproduced by being superimposed on the live view.

  Further, instead of allowing the image data itself to be stored (associated) in the object, metadata of the image data (for example, a shooting location and a shooting date / time) may be stored (associated) in the object. In this case, the image data itself can always be reproduced and viewed, but it is necessary to recognize the object in order to browse the metadata of the image data.

(Modification 5)
In each of the above-described embodiments, an example in which the present invention is applied to a digital camera has been described. However, the present invention can also be applied to other than a digital camera. For example, the present invention can be applied to a small communication terminal such as a mobile phone. Further, storage (association) to an object and reading of image data stored (associated) in the object may be performed by different devices. For example, a digital camera that stores image data in an object and a stationary personal computer that reads out stored image data may operate in conjunction with each other.

(Modification 6)
In each embodiment described above, several pieces of image data are stored (associated) with respect to one object. A certain object in which some image data is stored may be stored in another object. In other words, the nesting relationship between objects may be realized.

(Modification 7)
In the image storage mode, the position information of the recognized object may be stored in the object index 24. In the image reading mode, the CPU 101 can display a hint of the position of the object using this position information. For example, when the position of the object (the position represented by the stored position information) approaches the current position of the digital camera 1 by a certain amount or more, there is an object in which image data is stored (associated) nearby. Can be displayed on the display 116. Also, the position of the object can be indicated by the direction (for example, indicating that the object exists in the right direction).

  As long as the characteristics of the present invention are not impaired, the present invention is not limited to the above-described embodiments, and other forms conceivable within the scope of the technical idea of the present invention are also included in the scope of the present invention. .
