(Example 1)
A first embodiment of the present invention will be described below with reference to FIGS.
FIG. 1 is a block diagram showing basic components of the image photographing apparatus in this embodiment.
This image photographing apparatus uses a CCD image sensor or the like as an image pickup device, records and saves a photographed image (color image) obtained by photographing a subject, or transmits it to the outside via a mobile communication network. However, it may be a mobile phone or the like incorporating this kind of digital still camera. This image capturing apparatus simply registers a shooting point (point, time point) scheduled to be shot, and displays guidance for prompting shooting at that point when the shooting point is reached.
Before detailed description of the features of this embodiment, the hardware configuration of this embodiment will be described below.

  The image photographing apparatus includes a CPU 1, a camera optical system drive unit 2, an operation unit 3, a display unit 4, a memory 5, an internal recording unit 6, an external recording medium 7, a communication unit 8, a GPS communication unit 9, a clock unit 10, and a buzzer. 11 is a basic component. The CPU 1 is a central processing unit that controls the overall operation of the image photographing apparatus in accordance with an operating system and various application software. The camera optical system drive unit 2 includes a photographing lens, a lens / mirror block such as a mirror, an image pickup device such as a CCD image sensor, and a drive system thereof. The CPU 1 performs drive control and shutter drive control during autofocus. The captured image is taken in.

  The operation unit 3 has various buttons such as a shutter button and gives an operation signal to the CPU 1. The display unit 4 is, for example, a liquid crystal display unit, and is used as a monitor screen, a finder screen, and an image playback screen. The memory 5 is a ROM in which an operating system, various application software, and the like are stored, a work RAM, and the like. The program storage area in the memory 5 stores an application program for realizing the present embodiment according to the operation procedure shown in FIGS. 3 and 4 to be described later, and the data storage area in the memory 5 has Data (photographing schedule table etc.) shown in FIG. 2 to be described later is stored. The internal recording unit 6 is an internal memory for storing a stored image, and the external recording medium 7 is a removable image recording storage medium such as a DVD. The communication unit 8 wirelessly transmits a captured image via a wide area communication network (mobile communication network, Internet). The GPS communication unit 9 receives and obtains information from a position measurement system that measures the current position using a terrestrial / satellite control station, and the clock unit 10 performs a time measurement process that measures the current date and time. The buzzer 11 generates and outputs a warning sound that prompts photographing.

FIG. 2 is a diagram showing the contents of the shooting schedule table 12.
This shooting schedule table 12 stores and manages the shooting schedule for each shooting point scheduled to be shot. For each shooting point, “shooting point number”, “shooting time”, “shooting position”, “shooting target number” ”,“ Number of shots ”, and“ Shooting time ”,“ Shooting position ”, and“ Target number of shots ”other than“ Shooting point number ”and“ Number of shots ” Are arbitrarily registered.

 The “shooting point number” is a serial number that is automatically generated. “Shooting time” is information indicating the shooting time point, and the shooting date and time is registered as a shooting point. For example, when “shooting time” is registered as a shooting schedule according to a travel plan, each date and time may be registered in advance as shooting points. “Shooting position” is information indicating a shooting point, and longitude and latitude information and location information are registered as shooting points. For example, when “shooting position” is registered as a shooting schedule in accordance with a travel plan, a point indicating the location for each facility may be registered as a shooting point.

It should be noted that it is arbitrary whether one of “shooting time” and “shooting position” or both are registered as shooting points. For example, when shooting while moving within the same tourist facility, register the tourist facility as a “shooting position” and register multiple “shooting times” according to the action schedule in this facility. That's fine.
The “shooting target number” is a target value of the number of shots scheduled at the shooting point. The “number of shots” is the actual number of shots that is updated each time shooting is actually performed at the shooting point.

 In the state where “shooting time”, “shooting position”, and “shooting target number” are registered in association with each shooting point in the shooting schedule table 12, the CPU 1 displays the current position obtained by the GPS communication unit 9. The current date and time obtained by the clock unit 10 is acquired as the current point, and the current point is compared with “shooting time” and “shooting position” as shooting points registered in the shooting schedule table 12. Thus, it is determined whether or not the shooting point has been reached. When the shooting point is reached, guidance for prompting shooting at that point is displayed and output.

  Next, the operation concept of the image photographing apparatus in the first embodiment will be described with reference to the flowcharts shown in FIGS. Here, each function described in these flowcharts 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. This also applies to other embodiments described later, and in addition to the recording medium, operations specific to this embodiment can be executed using programs / data supplied externally via a transmission medium.

3 and 4 are flowcharts showing the overall operation of the image photographing apparatus.
First, the CPU 1 checks whether or not a button is operated (step A1), and when any button is operated, checks the type of the operation button (steps A2 to A4). Here, when the schedule button is operated (YES in step A2), the registration process to the imaging schedule table 12 is started. That is, an input designation of “shooting time” is accepted (step A5), and an input designation of “shooting position” is accepted (step A6). In this case, at the time of input designation of “shooting position”, the map information acquired from the network via the GPS communication unit 9 is displayed and output, and when an arbitrary place on the map is touch designated, Position information (longitude / latitude information) is acquired, and this position information is captured as a “shooting position”. Further, an input designation of “shooting target number” is accepted (step A6).

 When “shooting time”, “shooting position”, and “target number of shots” are input and specified in this way, a new record is generated and the entered “shooting time”, “shooting position”, “shooting” The “target number” and the automatically generated “shooting point number” are set in the corresponding items in the record and additionally registered in the shooting schedule table 12 (step A8). Then, it is checked whether or not the registration end is instructed (step A9). If there is no end instruction, the photographing point No is updated and then the process returns to step A5, and the above registration process is repeated thereafter (steps A5 to A9). .

 On the other hand, when the shutter button is operated (YES in step A3), the currently captured image is acquired, recorded and stored as an image file (step A10), and then the current position obtained by the GPS communication unit 9, The current date and time obtained by the clock unit 10 is acquired (step A11), and the shooting point in the shooting schedule table 12 is searched using the current date and time and current position as the current point (step A12). Thus, it is checked whether or not a shooting point that matches or approximates the current point is registered in the shooting schedule table 12 (step A13). In other words, in addition to checking whether "shooting time" matching the current date and time is registered or "shooting position" matching the current position, whether the current date falls before and after "shooting time" It is checked whether or not the current position corresponds to the vicinity of the “shooting position”.

If the corresponding shooting point is not registered (NO in step A13), the process returns to the first step A1, but if the corresponding shooting point is registered, the shooting schedule table 12 is stored based on this shooting point. Search and add “1” to the corresponding “number of shots” to update the value (step A14), and subtract “number of shots” from the “number of shots” corresponding to the point. After obtaining (difference), guidance display of the “shooting target number”, “number of shots”, and “remaining number” is performed (step A15).
FIG. 5 is a diagram showing an example of guidance display for guiding the current shooting situation. This display screen includes the current “shooting point No“ 3 ”” and its contents “shooting time” and “shooting”. “Position” is displayed as a guide, and “Target shooting number“ 10 ””, “Number of shots“ 7 ””, “Remaining number (difference)“ Minus 3 ”” is also displayed. Button "is displayed. When the “return button” is operated, the process returns to the first step A1.

 If the guidance button is operated (YES in step A4), the process proceeds to step 17 and subsequent steps in FIG. On the other hand, when any button is not operated (NO in step A1), it is checked whether or not a predetermined time (for example, 1 minute or 10 minutes) has passed since the previous photographing (step A16). That is, the measurement time is acquired from a timer (not shown) that is cleared and started every time shooting is performed, and it is checked whether or not a predetermined time has elapsed since the previous shooting. When the elapse of the predetermined time is detected, the process proceeds to step A17 and subsequent steps in FIG.

 First, the current position is acquired from the GPS communication unit 9 and the current date and time are acquired from the clock unit 10 (step A17), and a shooting point in the shooting schedule table 12 is searched based on the current date and time and current position (step A18). Check if there is a "shooting time" that matches the date and time or a "shooting position" that matches the current position, and check if the current date and time is before or after the "shooting time" or the current position is close to the "shooting position" (Step A19). If there is no corresponding shooting point (NO in step A19), the process returns to the first step A1, but if there is a corresponding shooting point, the “shooting target number”, “number of shots” corresponding to this shooting point. "Is read (step A20), and it is checked whether" number of shots "is less than" number of shots "(step A21). Initially, since the “number of shots” is equal to or less than the “shooting target number” (YES in step A21), a warning sound of the shooting guide is generated and output to prompt shooting at the shooting point (step A22). Then, the process proceeds to step A15 in FIG. 3, and the “number of shots” is subtracted from the “number of shots” at the shooting point, and the remaining number is displayed as guidance.

 As described above, in the first embodiment, the CPU 1 acquires the current position from the GPS communication unit 9 and the current date and time from the clock unit 10 in the state where the shooting schedule table 12 is registered, and the current position, current date and time are acquired. And the shooting point “shooting time” and “shooting position” in the shooting schedule table 12 to determine whether or not the shooting point has been reached, and when it is determined that the shooting point has been reached, Since guidance for prompting shooting at points is displayed, you can always provide timely shooting assistance guidance simply by registering shooting points that are scheduled to be shot, so you can forget to shoot at shooting points Can be prevented.

In this case, the “shooting target number” to be shot at the shooting point is registered in the shooting schedule table 12 in association with the shooting point, and when the shooting point is reached, the shooting target to be shot at that point. Since the guidance for the number of sheets is displayed, it is possible to prevent forgetting to take a predetermined number of shots when shooting for a plurality of shots is planned at the shooting point.
In addition, the guidance display shows the number of shots taken at the shooting point and the target number of shots at that point. You can easily know if it's not enough.

In addition, when displaying the guidance, the remaining number of shots is calculated from the “shooting target number” and “number of shots”, and the guidance is displayed. You can immediately check if you need to shoot.
Further, since the “number of shots” at the shooting point is guided, it is possible to check the actual number of shots actually shot at each shooting point.

  In the first embodiment described above, the map information acquired from the network via the GPS communication unit 9 is displayed and output when the “shooting position” is designated, and an arbitrary place on the map is touched. When specified, this position information (latitude and longitude information) was received and acquired, and this position information was taken in as the “shooting position”. However, by inputting the location name, telephone number, etc., the position information (background) Degree information) may be received and acquired. Further, the position information may be acquired by connecting a camera to a mobile phone.

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, the function of arbitrarily registering a shooting point scheduled to be shot, the function of acquiring the current point, and the acquired current point and the registered A function that determines whether the shooting point has been reached by comparing the shooting point with the current shooting point, and a function that outputs guidance that prompts shooting at that point when it is determined that the shooting point has been reached. It is also possible to provide a computer-readable recording medium in which a program for causing the program to be recorded is recorded.
(Example 2)

A second embodiment of the present invention will be described below with reference to FIGS.
In the second embodiment, only the shooting point and shooting target (shooting target) scheduled to be shot are registered, and when the shooting point is reached, the shooting target to be shot at that point is displayed as guidance. It is a thing. That is, in the state where the shooting point scheduled to be shot and the shooting target to be shot at that point are registered arbitrarily, the current point is acquired and the current point and the registered shooting point are By comparing, it is determined whether or not the shooting point has been reached, and when the shooting point is reached, the shooting target to be shot at that point is guided.
Here, the same or the same names in both embodiments are denoted by the same reference numerals, the description thereof will be omitted, and the following description will focus on the features of the second embodiment. .

FIG. 6 is a diagram showing the contents of the shooting target list 13.
This shooting target list 13 can store a plurality of subjects scheduled to be shot as shooting targets, and is configured to store “name”, “image”, and “ID” for each shooting target. Note that the subject to be photographed may be a person, a car, an animal, a building, a landscape, or the like. An “image” is an image obtained by photographing an object to be photographed in advance, and when the object to be photographed is a person, it is a face image photographed around the face. “ID” is identification information that is automatically generated to identify a subject to be imaged.

FIG. 7 is a diagram showing the contents of the shooting schedule table 12 in the second embodiment.
The shooting schedule table 12 stores “shooting point No”, “shooting time”, and “shooting position” for each shooting point as well as the first embodiment described above, and information on a plurality of shooting targets for each shooting point. The “photographing object ID” and the “number of photographed sheets” are stored. Here, “shooting time”, “shooting position”, and “shooting target ID” other than “shooting point number” and “number of shots” are arbitrarily registered by the user prior to shooting. A plurality of shooting targets can be registered for each.

8 and 9 are flowcharts showing the overall operation of the image photographing apparatus in the second embodiment.
First, the CPU 1 checks whether or not a button is operated (step B1), and if any button is operated, checks the type of the operation button (steps B2 and B10). If the schedule button is operated (YES in step B2), the registration process to the shooting schedule table 12 is started. First, as in the first embodiment described above, input designation of “shooting time” and “shooting position” is accepted (step B3).

 Next, the contents of the shooting target list 13 are read and a list of shooting targets is displayed (step B4). When a desired shooting target is arbitrarily selected from the list display (step B5), the shooting target ID is read from the shooting target list 13 (step B6). Here, in the case of selecting a plurality of shooting targets, after repeating the above-described operation until all the selections are completed (steps B4 to B7), a new record is generated and the input “shooting time”, The “shooting position” and “shooting target ID” are set together with the automatically generated “shooting point No” in the corresponding item in the record and additionally registered in the shooting schedule table 12 (step B8). Then, it is checked whether or not the registration end is instructed (step B9). If there is no end instruction, the photographing point No is updated, and then the process returns to step B3. .

 On the other hand, when the shutter button is operated (YES in step B10), the captured image is acquired and recorded (step B11), and the current position is acquired from the GPS communication unit 9 and the current date and time is acquired from the clock unit 10. (Step B12) Based on the current date and time and the current position, a shooting point in the shooting schedule table 12 is searched (Step B13), and the “shooting time” that matches the current date and time or the “shooting position” that matches the current position. It is checked whether there is a current date and time before or after the “shooting time” or whether the current position is in the vicinity of the “shooting position” (step B14).

 If there is no corresponding shooting point (NO in step B14), the process returns to the first step B1, but if there is a corresponding shooting point, the shot image is analyzed to extract all portions where the shooting target is shown. (Step B15). For example, when a person is shown in the photographed image, all the person portions centered on the face are extracted. Then, the shooting schedule table 12 is searched based on the shooting point to read out one “shooting target ID” corresponding to the point, and the shooting target list 13 is searched based on the “shooting target ID”. After the “photographing target image” is read, a feature comparison between all the partial images (photographing target images) extracted from the photographed image as described above and the “photographing target image” read from the photographing target list 13 is performed. (Step B16).

 In this case, if the subject to be imaged is a person, the face orientation, size, etc. are corrected, and then the shape, position, size, etc. of the face outline, eyes, mouth, nose, forehead, etc. are compared. In addition, person recognition is performed by comprehensively comparing presence / absence of glasses, hairstyle, and color. Now, as a result of comparing each extracted image extracted from the photographic image with the “photographing target image” read from the photographic target list 13, an image characteristically matching the “photographing target image” is included in each extracted image. In other words, if the registered shooting target is shown (YES in step B17), the shooting schedule table 12 is searched based on the “shooting point” and “shooting target ID”, and the corresponding “ A process of adding "1" to "number of shots" and updating the value is performed (step B18). If the registered shooting target is not shown (NO in step B17), "" Is skipped. If a plurality of “shooting object IDs” corresponding to the “shooting point” are registered in the shooting schedule table 12, the image comparison for all of the shooting targets is completed (step B19). Returning to the above-described step B16, the above-described operation is repeated thereafter.

 On the other hand, when neither the schedule button nor the shirt button is operated (NO in step B10), it is checked whether or not a predetermined time (for example, 1 minute or 10 minutes) has passed since the previous shooting (step in FIG. 9). B20). That is, as in the first embodiment described above, the measurement time is acquired from the timer, and it is checked whether or not a predetermined time has elapsed since the previous shooting. If the predetermined time has not elapsed, the process returns to the first step B1, but the predetermined time has elapsed. Is detected, the current position is acquired from the GPS communication unit 9 and the current date and time are acquired from the clock unit 10 (step B21), and a shooting point in the shooting schedule table 12 is searched based on the current date and time and the current position. (Step B23) It is checked whether there is a “shooting time” that matches the current date and time or a “shooting position” that matches the current position, and the current date is before and after the “shooting time” or the current position is in the vicinity of the “shooting position”. (Step B23).

If there is no corresponding shooting point (NO in step B23), the process returns to the first step B1, but if there is a corresponding shooting point, each “number of shots” corresponding to this shooting point is read, and “ It is checked whether or not there is an imaging target whose “number of shots” is “0”, that is, an imaging target that has not been shot yet (step B24). Here, if there is no unphotographed object (NO in step B25), it is checked whether the photographing status button has been operated (step B28). If the button is not operated, the process returns to the first step B1. If there is an unphotographed target (YES in step B25), a shooting warning alarm sound to that effect is generated and output (step B26), and the “name” and “image” of the unphotographed target are displayed in the photographing target list 13. Is read out and the guidance is displayed (step B27).
FIG. 10 is a diagram illustrating a guidance display example of an unphotographed target. On this guidance screen, the “name” and “image” of the shooting target that has not been shot at the current shooting point are displayed in guidance, and “shooting status buttons” are arranged and displayed.

Here, when the above-described shooting state button is operated, this is detected in step B28, and the process proceeds to step B29. The shooting schedule table 12 is searched based on the current shooting point, and each shooting corresponding to the point is performed. The “photographed number” is read for each object, and the “photographed number” is displayed in a list (step B30).
FIG. 11 is a diagram showing a list screen for providing guidance on the shooting status at the current shooting point. On this screen, “shooting time” and “shooting position” that are the contents of the current shooting point are guided and displayed. At the same time, the number of shots for each shooting target is guided and displayed, and a “return button” is arranged and displayed. In the example shown in the figure, the number of shots of “Mr. XX” is “0”, indicating that no shot has been taken. When the “return button” is operated, the process returns to the first step B1.

  As described above, in the second embodiment, the CPU 1 acquires the current position from the GPS communication unit 9 and the current date and time from the clock unit 10 in a state where the shooting schedule table 12 is registered. And the shooting point “shooting time” and “shooting position” in the shooting schedule table 12 to determine whether or not the shooting point has been reached, and when it is determined that the shooting point has been reached, Since the shooting target to be shot at the point is displayed as a guidance, the shooting target to be shot at that point when the shooting point is reached simply by registering the shooting point and shooting target to be shot. It is possible to guide, and it is possible to prevent forgetting to shoot at the shooting point by always timely shooting assistance guidance Become.

In this case, when the shooting target is displayed as a guidance, the current shooting status of the shooting target is displayed as a guidance. For example, whether or not the shooting target is shot as planned at the current time, the number of shots taken, etc. Can be known specifically.
In addition, since the guidance of the photographing object photographed at the photographing point is displayed, it is possible to easily confirm whether the photographing was performed as scheduled immediately after photographing.

 The CPU 1 recognizes whether the registered photographing target is included by recognizing whether or not the registered photographing target is included in the captured image by analyzing the captured image captured at the photographing point. In such a case, the guidance output is made so that it is possible to automatically recognize and guide the photographing object by image analysis. In this case, in the state where the shooting target is registered and managed as an image, the CPU 1 recognizes whether or not the shooting target image is included in the shot image by analyzing the shot image. A subject to be photographed can be reliably recognized by comparison with an image registered as a subject to be photographed.

Since the CPU 1 displays a guidance indicating which shooting target was shot among a plurality of shooting targets registered in association with shooting points, even if a plurality of shooting targets are registered as shooting points, It is possible to specifically know whether or not shooting is performed for each shooting target.
In addition, since guidance output is performed on an unphotographed shooting target among a plurality of shooting targets associated with the shooting point, it is possible to immediately check an unshot shooting target among the plurality of shooting targets. .

 In the second embodiment, the number of shots is displayed as a guidance as the current shooting state of the shooting target. However, as in the first embodiment, the remaining number is displayed as a guidance. Good.

  On the other hand, you may make it provide the recording medium which each recorded the program code for making a computer perform each means mentioned above. That is, a recording medium having a computer-readable program code, a function of arbitrarily registering a shooting point scheduled to be shot and a shooting target to be shot at that point, and a function of acquiring the current point A function for determining whether the shooting point has been reached by comparing the acquired current point with the registered shooting point, and if it is determined that the shooting point has been reached, shooting is performed at that point. It is also possible to provide a computer-readable recording medium that records a program for realizing a function of outputting guidance for a shooting target to be recorded.

In the first and second embodiments described above, the case where a digital still camera is applied has been exemplified. However, the present invention is not limited to still images and can be applied basically to video cameras as well.
Furthermore, the present invention can be applied not only to a handy type camera but also to an installation type surveillance camera and the like, and also to an electronic device with a built-in camera.
