DETAILED DESCRIPTION OF THE INVENTION
(First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a block diagram showing the basic components of a digital still camera device according to this embodiment.
This digital still camera device is a handy-type camera (personal camera), and has a function of reading a captured image taken in color through a solid-state image pickup device in a recording medium, and a function of reading out and reproducing the stored image. is doing.
In particular, the still camera device in this embodiment registers the target image (person image) for each target (person) scheduled to be photographed, and the result of analyzing the photographed image based on the registered target image, Based on whether or not a registered target (expected photographer) is included in the captured image, the shooting status is recognized for each registered target, and guidance information corresponding to the shooting status for each registered target is created and displayed. It is designed to output.
[0020]
Here, the shooting status of the registered target indicates the “shooting actual number” of the registered target that has actually been shot up to the present time with respect to the “scheduled number of shots” registered in advance for each registered target. “Remaining number of images” obtained by subtracting “actual number of images” from “scheduled number of images”. When guiding and outputting the shooting status for each registered target, a “current status list” indicating “scheduled number of shots”, “actual number of shots”, and “remaining number of shots” is created for each registered target.
Prior to detailed description of the features of this embodiment, the hardware configuration of this embodiment will be described below.
[0021]
The CPU 1 is a central processing unit that controls the overall operation of the still camera device in accordance with the operating system and various application software in the storage unit 2. The storage unit 2 includes a program storage area and a data storage area, and is configured by a magnetic, optical, semiconductor memory, or a drive system thereof. The recording unit 2 may have a configuration in which a removable storage medium such as a CD-ROM or DVD can be mounted in addition to a fixed memory such as a hard disk.
The recording medium 3 for recording and storing a photographed image is a detachable one constituted by a CD-ROM, a DVD or the like, and the photographed image photographed every time the photographing button is operated is recorded and preserved.
[0022]
On the other hand, a key input unit 4, a display unit 5, and a camera photographing unit 6, which are input / output peripheral devices, are connected to the CPU 1 through a bus line, and the CPU 1 controls their operations according to an input / output program.
The key input unit 4 is an operation unit constituting a keyboard or a touch panel (touch screen), and has various buttons such as a shooting button and a playback button, and inputs various commands and character string information. The display unit 5 is a liquid crystal display unit that performs full-color display, and is used as a finder screen, an image reproduction screen, and a touch screen.
The camera photographing unit 6 has a normal configuration including various electronic components such as an area sensor (solid-state imaging device) that receives a subject image captured through an optical system, an analog / digital conversion unit, and an autofocus unit. Although not shown, the camera body is provided with an external connection terminal that is connected to an image processing apparatus or the like, so that externally supplied image information can be taken in.
[0023]
FIG. 2A shows the contents of the registration table 21 provided in the storage unit 2.
The registration table 21 stores and manages information about registered targets for each target (person) scheduled to shoot. The “registration ID” and “person name” for each target who is a shooter. Each item of “scheduled number of shots” and “actual number of shots” is stored.
“Registration ID” is a serial number that is automatically generated at the time of person registration in order to identify a person as a person who is scheduled to shoot. “Person name” and “Scheduled number of shots” are key operations as information about attendees for each attendee that the photographer plans to shoot, for example, when shooting at a wedding venue or party venue. When the “person name” and “expected number of shots” are registered, the “person image” obtained by shooting the person in advance is also registered.
[0024]
This “person image” is, for example, a face image of the person (an image taken around the face), and is stored in the registered image file 22 in the storage unit 2. FIG. 2B shows a registered image file 22, and this registered image file 22 stores a person image in a one person one file format. This registered image file 22 includes a “registration ID” corresponding to the person. "Is added. Here, when registering a “person image”, the CPU 1 registers, for example, an image arbitrarily input and supplied from the outside as a “person image”, or from among captured images stored in the recording medium 3. An image arbitrarily selected and designated is registered as a “person image”.
[0025]
“Actual number of shots” indicates the number of shots in which a registered person (registered target) is actually shot so far. Here, every time the shooting button is operated, the CPU 1 records and saves the shot image as a shot image file 31 in the recording medium 3 (see FIG. 2C), and also registers the shot image file 31 and each registration. When image analysis is performed to check whether or not any registered person is included in the captured image by comparing the image with the image file 22, and when it is recognized that the registered person is included, The “actual shooting number” corresponding to the person is updated.
This “actual shooting number” update process is performed under the condition that it is set to a predetermined operation mode (check mode). This “check mode” is automatically performed after target registration. The operation mode is set, and an operation mode for checking whether any registered person is included in the photographed image is designated.
[0026]
Next, the operation concept of the still camera device in the first embodiment will be described with reference to the flowchart shown in FIG. Here, each function described in the flowchart is stored in the form of a readable program code, and operations according to the program code are sequentially executed. It is also possible to sequentially execute operations according to the program code transmitted via the transmission medium. The same applies to other embodiments to be described later. In addition to a recording medium, an operation peculiar to this embodiment can be executed using a program / data supplied externally via a transmission medium.
[0027]
FIG. 3 is a flowchart showing the overall operation of the still camera apparatus that is started when the power is turned on.
First, the CPU 1 monitors the presence or absence of an operation as the power is turned on (step A1). If any operation is performed, the CPU 1 checks whether target registration is instructed (step A2). Now, before you start shooting at a wedding venue or party venue, if the registration button is operated to register the person concerned as a shooting target, you will be asked to enter information about the person to be registered The registration process is performed (steps A3 to A7).
[0028]
Here, the CPU 1 inputs and supplies an arbitrary image as a “person image” from the outside, or designates an image arbitrarily selected from photographed images stored in the recording medium 3 as a “person image”. If it is (step A 3), the input “person image” is captured, a “registration ID” is generated, and the “person image” with this “registration ID” is stored in the registered image file 22. (Step A4).
Here, when the “person name” and “scheduled number of shots” are input (step A5), the “person name” and “scheduled number of shots” are written in the registration table 21 together with the “registration ID”. Perform (Step A6). As a result, the registered image file 22 and the contents of the registration table 21 are associated with each other via the “registration ID”.
After registration for one target is completed in this way, it is checked whether registration of another target has been instructed (step A7). If another registration instruction has been received, the process returns to step A3. The registration process is repeated (steps A3 to A7), but when the end of registration is instructed (step A7), the check mode is set as a condition (step A8).
[0029]
After the target registration as described above, when the shooting button is operated to start shooting (step A9), the shot image at that time is captured and recorded as the shot image file 31 in the recording medium 3. Save (step A10). Then, it is checked whether the “check mode” is set (step A11). If the “check mode” is cancelled, that is, if the target is not registered, the operation returns to the first step A1 Although it will be in a waiting state, if it is after target registration, since it is set to "check mode", execution of the following check processing is started.
[0030]
That is, a person image is extracted from the current captured image (photographed image file 31) (step A12), and the registered image file 22 is accessed based on the “registration ID” for one person read from the top of the registration table 21. Then, the person image included in the photographed image file 31 is compared with the registered image file 22 (step A14), and it is checked whether the person image in the photographed image is a registered person (step A13). Step A15). In this case, the characteristics of the human image are compared. At that time, after correcting the face orientation, size, etc., the shape, position, size, etc. of the face outline, eyes, mouth, nose, forehead, etc. are compared. . In addition, person recognition may be performed by comprehensively comparing gender, face, presence / absence of glasses, height, body shape, hairstyle, and color.
[0031]
If it is recognized that the person image in the photographed image corresponds to the registered person (YES in step A15), the “photographing actuality” in the registration table 21 associated with the “registration ID” of the person is identified. An update process of adding “1” to “number of sheets” is performed, and the value is counted up (step A16). When the process per registered person is completed in this way, it is checked whether another person is registered in the registration table 21 (step A17). If there is an unprocessed registered person, step A13 is checked. Returning to step S4, after specifying the next unprocessed registered person, the above operation is repeated (steps A13 to A17).
Thus, every time the photograph button is operated and the photographed image is saved, a registered person shown in the photograph is specified, and a process of updating the “actual photograph number” corresponding to this person is performed. When a plurality of registered persons are photographed at the same time, the “actual number of photographs” of each person is updated. When the processing for all registered persons is completed (step A17), the process returns to the initial operation waiting state (step A1).
[0032]
Now, during shooting at a wedding hall, party hall, etc., for example, when the guide button is operated in order to confirm whether all of the related persons have been shot (step A18), the CPU 1 registers the registration table 21. For each registered person, read the “person name”, “scheduled number of shots”, and “actual number of shots” and subtract “actual number of shots” from “scheduled number of shots”. Number ”(step A19). Then, for each registered person, a list in which the “person name”, “scheduled number of shots”, “actual number of shots”, and “remaining number of shots” are arranged is created, and this list shows the shooting status of each registered person. Guidance is displayed as “current status list” (step A20).
Such a guidance display is generated and guided and output any number of times each time the guide button is operated, so that the photographer can freely check the current shooting situation at any time.
[0033]
As described above, in the still camera device according to the first embodiment, the CPU 1 registers the person image as the registered image file 22 for each target scheduled to be photographed, and information on the person in the registration table 21. As a result of analyzing the photographed image based on this registered person image, the photographing situation is recognized for each registered person based on whether or not the registered person is included in the photographed image, and this registered person Since the guidance information corresponding to each shooting situation is created and output, in order to shoot all the people who are scheduled to shoot (for example, all related persons), who and how much, and who It is possible to provide information on whether or not the image has been taken, and it is possible to realize appropriate shooting assistance without bias and without forgetting to take a picture, which is highly practical.
[0034]
In this case, for each registered person, calculate by subtracting the “number of actual shots” from the “planned number of shots” set in advance, the “number of shots actually taken” up to the present time, and the “number of planned shots”. The current status list including the “remaining number of shots” is created and displayed as a guide, so that each registered person can know the shooting status in detail and accurately perform shooting for the scheduled amount. can do.
In addition, it is possible to select whether an image input / supplied from outside is registered as a person image or registered as a person image using an image captured in the past, and the registration work can be easily performed. It becomes possible.
[0035]
In the first embodiment described above, the current status list is guided and displayed in response to the operation of the guide button. However, for example, the current status list is automatically created and guided at a preset time arbitrarily set. You may make it display.
In the first embodiment described above, a current status list including “scheduled number of shots”, “actual number of shots”, and “remaining number of shots” is created and displayed for each registered person. Only the “number of sheets” may be guided and output, or a registered person whose “number of remaining sheets” is “1” or more may be detected, and “the number of remaining sheets” may be guided and output together with the “person name”. Good.
[0036]
In the first embodiment, a person is exemplified as a target to be photographed. However, a car, a building, an animal, or the like other than a person may be registered as a photographing target. Moreover, although the above-described first embodiment exemplifies the case where a digital still camera is applied, the present invention is not limited to a still image and can be applied basically to a video camera as well. In this case, “Scheduled number of shots”, “Actual number of shots”, and “Remaining number of shots” are “Scheduled number of shots” and “Actual number of shots” that indicate the shooting time (seconds / minutes) and the amount of recorded images (in bytes) , “Remaining sheet quantity”. Furthermore, the present invention is not limited to a handy type camera, and can be applied to an installation type surveillance camera or the like.
[0037]
On the other hand, a recording medium (for example, a CD-ROM, a floppy disk, a RAM card, etc.) on which a program code for executing each of the above-described units is recorded may be provided to the computer.
That is, a recording medium having a computer-readable program code, a function for registering a target image for each target scheduled to be shot, and a function for analyzing a shot image based on the registered target image As a result of image analysis, a function for recognizing the shooting status for each registered target based on whether or not the registered target is included in the shot image, and guidance according to the shooting status for each recognized registered target You may make it provide the computer-readable recording medium which recorded the program for implement | achieving the function which produces and outputs information.
[0038]
(Second Embodiment)
Hereinafter, a second embodiment of the present invention will be described with reference to FIGS.
In the above-described first embodiment, for each person who is scheduled to shoot, only the person image is registered, and guidance information corresponding to the shooting situation of each registered person is created and output. In the second embodiment, the person image to be photographed is registered, and the photographing schedule information is registered, and the registered person should be photographed according to the schedule in sightseeing trips and events. Guide information is created and output. That is, in the second embodiment, the person image to be photographed is registered and the photographed image is analyzed based on the person image. However, in the second embodiment, the registered person is assigned to the schedule. The camera assists the camera to output information indicating what should be photographed on the street.
Here, components that are basically the same in both embodiments are denoted by the same reference numerals, description thereof will be omitted, and the following description will focus on the features of the second embodiment.
[0039]
FIG. 4 is a block diagram showing basic components of the digital still camera device according to the second embodiment.
As basic components of the still camera device, there are the CPU 11, the storage unit 12, the recording medium 13, the key input unit 14, the display unit 15, and the camera photographing unit 16 described in the first embodiment (FIG. 1). However, the second embodiment further includes a clock unit 17 and a position detection unit 18, and the other configuration is the same as that of the first embodiment. The clock unit 17 and the position detection unit 18 are provided especially for photographing schedule monitoring, the clock unit 17 measures the current date and time, and the position detection unit 18 moves the ground system / satellite system. The current position (camera position) is acquired using the body communication service, and is connected to the mobile communication service network.
[0040]
FIG. 5A shows the contents of the registration table 21 in the second embodiment.
The registration table 21 includes a “registration ID” and a “photographed flag” for specifying a plurality of persons scheduled to shoot for each “location” and “time zone” indicating a shooting schedule that is a shooting schedule. It has a configuration to memorize. In the figure, “ID1” to “ID4” indicate “registration IDs” for specifying four persons who are scheduled to shoot, and each “f” associated with this “registration ID” is “shooting”. "Finished flag". It should be noted that the number of persons scheduled to shoot is not limited to four and of course is arbitrary. Here, for example, in the case of sightseeing trips and events, when the photographer knows who and when to shoot is even more effective, the photographer preliminarily “place”, “time zone” In this embodiment, at least one of “location” and “time zone” is registered, and the shooting schedule of who and where to shoot is to be registered. Is registered in association with the “location”, and in the case of registering the shooting schedule of who is to be photographed at what time, the shooting person is registered in association with the “time zone”. In the case of registering and registering the shooting schedule of who should take a picture at what time and where, the scheduled shooting person is registered in association with “location” and “time zone”.
[0041]
“Location” and “Time zone” as the shooting schedule are information input by the photographer in advance by key operation, and “Location” specifically indicates “place name”, “facility name”, etc. Yes, the CPU 1 compares the current position information (location information) acquired from the position detection unit 18 with the location information as the shooting schedule, and determines whether the current location is the planned shooting location. The “registration ID” is a serial number that is automatically generated every time a person image is registered in order to identify a person as a person who is scheduled to shoot. The “person image” is also registered. The “photographed flag” is a flag that is set when a registered person is photographed according to the schedule.
[0042]
The “person image” is a face image of the person (image taken around the face), and is stored in the registered image file 22 in the storage unit 2. FIG. 5B shows a registered image file 22, which stores a person image in a one person one file format. This registered image file 22 includes a “registration ID” corresponding to the person. "Person name" is added. Here, when registering a “person image”, the CPU 1 registers, for example, an image arbitrarily input and supplied from the outside as a “person image”, or from among captured images stored in the recording medium 3. An image arbitrarily selected and designated is registered as a “person image”.
[0043]
In a state where a desired shooting schedule is registered in the registration table 21, the CPU 1 acquires the “location” and “time zone” registered in the registration table 21 from the clock unit 17 and the position detection unit 18. By comparing the current time information and position information, the current location is constantly monitored as to whether it is a registered location (scheduled shooting location) and whether it is currently a registered time zone (scheduled shooting time). If it is a “location” or “time zone” scheduled to be shot, the person who is scheduled to shoot in that location and time zone is identified, and a list of the scheduled shooting people is created and displayed as guidance. I am doing so.
[0044]
Each time the photographing button is operated, the CPU 1 records and saves the photographed image at that time as a photographed image file 31 in the recording medium 3 (see FIG. 5C), and extracts from the photographed image file 31. The person image is compared with each registered image file 22 to perform image analysis to check which registered person corresponds to the person captured in the photographed image. When it is recognized that it is included, that is, when it is recognized that a registered person has been photographed, a “photographed flag” corresponding to the registered person is set in addition to setting a “photographed flag” corresponding to the registered person. The non-photographer list is created by identifying the non-photographers with reference to the above, and this non-photographer list is displayed as a guide.
[0045]
Next, the operation concept of the still camera device in the second embodiment will be described with reference to the flowcharts shown in FIGS.
6 to 9 are flowcharts showing the overall operation of the still camera device that is started to be executed when the power is turned on.
First, in the operation waiting state (step B1 in FIG. 6), if any operation is performed and if it is a registration button (step B2), the CPU 1 proceeds to a registration process for registering a person image or the like. (Steps B3 to B15). Here, a check mode selection list screen is displayed with the start of the registration process (step B3).
[0046]
The check mode selection list screen is a screen that displays a list of selection candidates in order to execute schedule monitoring according to the type of schedule arbitrarily selected in advance in the “check mode”. The items “1: location priority”, “2: time zone priority”, and “3: location / time zone” are displayed as selection candidates. The item “1: location priority” is “3: location / time zone” when only location information is registered as a shooting schedule, and the item “2: time zone priority” is only registered for time zone information. The item is an item selected when both location information and time zone information are registered.
When an arbitrary item is selected as the schedule monitoring mode from the selection list screen (step B4), the corresponding schedule monitoring mode is set based on the selected item (step B5). That is, when “1: location priority” is selected, “location monitoring mode” is set, and when “2: time zone priority” is selected, “time zone monitoring mode” is set, When “3: location / time zone” is selected, “location / time zone monitoring mode” is set.
[0047]
After setting the desired schedule monitoring mode by selecting an arbitrary item from the selection list screen in this way, the CPU 1 determines the selection mode (step B6), performs the corresponding input process, The input of location information and time zone information is accepted (steps B7 to B9). That is, if the selection mode is “location monitoring mode”, input of location information is accepted (step B7), and if it is “time zone monitoring mode”, input of time zone information is accepted (step B8). If it is “time zone monitoring mode”, input of location information and time zone information is accepted (step B9). In addition, when inputting location information and time zone information, in addition to direct input by key operation, a list of selection candidates prepared in advance is displayed, and an input format for selecting and specifying a desired candidate is also included. It has been adopted.
[0048]
Next, the CPU 1 accepts input of information related to the person to be registered and performs the registration process. That is, when an arbitrary image is input and supplied as a “person image” from the outside, or an image arbitrarily selected from photographed images stored in the recording medium 3 is input and designated as a “person image” (Step B10) After receiving the input of the “person name” (step B11), the input “person image” and “person name” are taken in, and a “registration ID” is generated. "," Person image "with" person name "is stored as the registered image file 22 (step B12). Then, the location information / time zone information or location information / time zone information input according to the selection mode (schedule monitoring mode) and the automatically generated “registration ID” are written in the registration table 21 and registered (step) B13).
[0049]
After the registration for one target is completed in this way, it is checked whether registration of another target has been instructed (step B14). If another registration instruction has been received, the process returns to step B10. By repeating the registration process described above, registration for a plurality of persons becomes possible, and information for one record is written in the registration table 21 (steps B10 to B15). If the end of registration is not instructed (NO in step B15), the process returns to step B6 to perform registration for other records, and the above-described operation is repeated thereafter (steps B6 to B15). As a result, when all registrations for the scheduled shooting are completed, the process proceeds to step B16 in response to the end instruction, and after setting to "check mode", a "guidance completed flag" to be described later is reset (step B17). ). When such target registration is completed, the process returns to the initial operation waiting state (step B1).
[0050]
On the other hand, in the operation waiting state, the process proceeds to step B18 in FIG. 7 to check whether or not the “check mode” is set. If the “check mode” is canceled, that is, the target is not registered. If so, the process returns to the first step B1 and waits for an operation, but if it is after target registration, since it is set to “check mode”, the process proceeds to step B19, and further the “guidance completed flag” is set. Check if it is set. This “Guided flag” is a flag that is set when a guidance display that guides the planned shooting person list or the non-photographer list is performed according to the shooting schedule. Then, the process returns to step B1 to be in an operation waiting state. However, since the “guidance completed flag” is reset at the time of initial target registration, the guidance process for the prospective photographer is performed thereafter.
[0051]
First, the currently selected selection mode (schedule monitoring mode) is determined (step B20). If this selection mode is “location monitoring mode”, the current position information is acquired from the position detector 18 (step B20). B22) The registration table 21 is accessed, each registered “location” is read out, and the location is compared, and it is checked whether the current location matches any registered location (step B23).
If the current location does not match any registered location (NO in step B23), the process proceeds to the first step B1 and enters an operation waiting state. Similarly, when the “time zone monitoring mode” is selected (step B21), the current date and time information is acquired from the clock unit 17, and then each “time zone” registered in the registration table 21 is obtained. It is checked whether the read date and current date and time belong to any registration time zone (match) (step B24). Here, when it does not correspond to any registration time zone, it will be in the operation waiting state (step B1).
[0052]
If the “location / time zone monitoring mode” is selected (step B25), in addition to acquiring the date / time information from the clock unit 17, the current position information is acquired from the position detection unit 18 (step B25). B25), reading each “location” registered in the registration table 21 and checking which registered location the current location matches. If the current location matches any registered location, The “time zone” associated with the registration location is read from the registration table 21, and it is checked whether the current date matches the registration time zone (step B26). If the current location does not match any registered location or the location matches, but the current date does not match the registered time zone (NO in step B26), the process moves to step B1 to enter an operation waiting state. Become.
[0053]
When a match with the schedule content is detected by schedule monitoring according to such a selection mode, that is, when YES is determined in any of steps B23, B24, and B26, the condition of this selection mode ( All the “registration IDs” associated with the “schedule contents” are read from the registration table 21 (step B27), and the registered image file 22 is accessed based on the respective “registration IDs”. "Person name" is read out (step B28). Then, a scheduled photographer list is created based on the “person image” and “person name” corresponding to each “registration ID” (step B29).
This scheduled photographer list provides guidance on the current location and time zone to be photographed, as well as the “person image” and “person name” for each person scheduled to shoot in that location and time zone. It is a table. Then, the created list is displayed as a guidance (step B30), and after the “guidance completed flag” is set (step B31), the operation waiting state is returned (step B1).
[0054]
The photographer who has confirmed this list of scheduled photographers starts photographing according to the contents of the list. Now, in an operation waiting state (step B1), if any operation is performed and it is a shooting button (step B32 in FIG. 8), the captured image at that time is captured and recorded as a captured image file 31 in the recording medium 3. Save (step B33). In this case, it is checked whether or not the “check mode” is set (step B34). If it is not set to the “check mode”, the process returns to the operation waiting state (step B1) but is set to the “check mode”. In this case, the guidance process for the non-photographer is performed thereafter.
[0055]
Also in this case, the currently selected selection mode (schedule monitoring mode) is determined (step B35), and basically the same schedule monitoring as that of steps B21 to B26 of FIG. 7 described above is performed according to the selection mode. (Steps B36 to B42). That is, if the selection mode is “location monitoring mode”, after the current position is acquired (step B38), it is checked whether the current location matches the registered location (step B39), and the “time zone monitoring mode” is selected. If there is, it is checked whether the current date and time matches the registered time zone (step B40). If it is “location / time zone monitoring mode”, the current location is acquired (step B41), and the current location is any one. It is checked whether the current date / time also matches the registration time zone associated with the registration location (step B42).
[0056]
If a match with the schedule content is detected by schedule monitoring according to such a selection mode, the process proceeds to step B43, where the image (photographed image file 31) photographed this time is analyzed, and the photographed image is included in the photographed image. If a person is shown, the person image is extracted. In this case, when a plurality of persons are shown in the photographed image, all the person images are extracted.
Then, all the “registration IDs” associated with the selection mode conditions (schedule contents) are read from the registration table 21, and the registered image file 22 is accessed based on the respective “registration IDs”. The “registered person image” is read out and compared with the “photographed extracted image” extracted from the current photographed image (step B44).
[0057]
Here, when comparing images between a “registered person image” and a “photographed extracted image”, if there are multiple persons in the captured image, pay attention to that person's “photographing”. An image comparison between the “extracted image” and the “registered person image” is performed, and it is checked whether or not the “photographed extracted image” corresponds to any “registered person image” (step B45 in FIG. 9). That is, it is checked whether or not a person who is scheduled to photograph is included in the image photographed this time.
Now, when it is recognized that the person to be photographed is not captured (NO in step B45) without corresponding to any of the “registered person images”, there is another extracted person, that is, the photographed image. It is checked whether or not another person is captured (step B48). If another person is captured, the "photographed extracted image" and "registered person image" Image comparison is performed, and it is checked whether or not this “photographed extracted image” corresponds to any “registered person image” (step B45).
[0058]
As a result of the image comparison between the “photographed extracted image” and the “registered person image” as described above, when this “photographed extracted image” corresponds to any of the “registered person images”, that is, this time, When a person who is scheduled to shoot is shown in the image (YES in step B45), the "shooting flag" in the registration table 21 associated with the person (registration ID) is referred to. It is discriminated whether or not it has been set (step B46), and if the person has not been photographed, the "photographed flag" corresponding to this registration ID is set (step B47). Hereinafter, when a plurality of persons are shown in the photographed image, the above-described operation is repeated while paying attention to the persons one by one (steps B45 to B48).
[0059]
Thereafter, the registration table 21 is accessed to search for “registration IDs” in which the “photographed flag” has been reset among the “registration IDs” associated with the selection mode conditions (schedule contents). As a result, a search is made for unphotographed persons who have not been photographed at the present time among the prospective photographers corresponding to the conditions of the selection mode (step B49). Here, if there is no unphotographed person (NO in step B50), it is a case where all the prospective photographers have been photographed normally, and thereafter, since the guidance display becomes unnecessary, the “ All “guidance completed flags” corresponding to “registration ID” are set (step B54).
[0060]
On the other hand, if there is one person not photographed, the registered image file 22 is accessed based on the “registration ID” of this person, and the corresponding “person image” and its “person name” are read (step B51). A non-photographer list is created based on “person image” and “person name” (step B52), and this non-photographer list is displayed as a guidance (step B53). In addition to guiding the current location and time zone to be photographed, this list of non-photographers lists the “person image” and “person name” for each non-photographer who has not taken photos in that location or time zone. It is a list to guide. Thereafter, the process returns to step B1 in FIG.
[0061]
As described above, in the still camera device according to the second embodiment, the CPU 1 registers the person image as the registered image file 22 for each target scheduled to be photographed, and registers the photographing schedule information in the registration table 21. As a result of analyzing the photographed image based on the registered person image, it is recognized whether or not the registered person is included in the photographed image, and the registered person is photographed according to the photographing schedule. Since the registered person is guided and output that the registered person should be photographed according to the schedule, it is possible to provide specific photographing assistance guidance as to who and how to photograph at the time of photographing. It is possible to shoot more effectively without missing a chance and to prevent forgetting to take a picture. It becomes high results.
[0062]
In this case, the person image to be photographed and the location where the person is to be photographed are registered, and the registered person is guided to be photographed at the photographing location. It becomes possible to guide to.
In addition, the person image to be shot and the time zone for shooting the person are registered, and the registered person is guided to shoot in the shooting time zone. It becomes possible to guide to.
Furthermore, if the shooting location is registered together with the time zone for shooting the person scheduled to shoot, it is possible to guide who and where to shoot.
[0063]
In addition, as a result of comparing the shooting location, shooting time zone with the current position, date and time, if the current time is a registered location, registered time zone, the shooting schedule in that location, time zone will be guided Without any special operation, timely guidance is always possible and the current shooting schedule can be known on the spot.
In addition, when the registered person is not photographed according to the photographing schedule, the list of unphotographed persons is created and displayed as guidance. It is possible to know whether the camera has been photographed and to prevent forgetting to photograph.
In addition, the target images are registered in correspondence with a plurality of targets, and the shooting schedule is registered for each target, so that it is possible to guide that each target should be shot according to the schedule. This is effective when performing complex shooting.
[0064]
In the second embodiment described above, the “scheduled photographer list” and the “non-photographer list” are displayed as guidance. However, in addition to this guidance display, when the registration location and the registration time zone are reached, The contents may be guided by a voice message.
Also, as the shooting schedule, register the scheduled number of shots for each scheduled shooting person, count the actual number of shots actually taken, and obtain the remaining number by subtracting the actual number of shots from the planned number of shots If the output is made, it is possible to provide shooting assistance guidance for who, when, where and how many shots.
[0065]
Further, in the second embodiment, a person is exemplified as a target to be photographed. However, a car, a building, an animal, etc. other than the person may be registered as a target. Although the case where the camera is applied has been illustrated, the present invention is not limited to still images, and can of course be similarly applied to a video camera. Furthermore, the present invention is not limited to a handy type camera, and can be applied to an installation type surveillance camera or the like.
[0066]
On the other hand, a recording medium (for example, a CD-ROM, a floppy disk, a RAM card, etc.) on which a program code for executing each of the above-described units is recorded may be provided to the computer.
That is, a recording medium having a computer-readable program code, which registers a target image to be shot, and registers the shooting schedule information, and analyzes the shot image based on the registered target image The function and the result of image analysis, it recognizes whether the registered target is included in the captured image, recognizes whether the registered target was captured according to the shooting schedule, and registered based on the recognition result You may make it provide the computer-readable recording medium which recorded the program for implement | achieving the function which produces and outputs the guidance information for guiding that the target should be image | photographed according to the schedule.
[0067]
