And a photographing auxiliary guide means for outputting.
Furthermore, a program for realizing the main functions shown in the invention described in claim 13 is provided to the computer (the invention described in claim 16).

The invention described in claim 13 may be as follows.
The discriminating means discriminates whether the shooting has been changed from indoor shooting to outdoor shooting or from outdoor shooting to indoor shooting by comparing the brightness of the shot image shot this time and the previously shot shot image ( (Invention of Claim 14)

  When insert information indicating an insert image is added to a photographed image taken after guiding the insert photographing, when a plurality of photographed images are designated and reproduced and displayed during image reproduction. It is checked whether or not insert information is added to the next image positioned next to the designated image designated as the reproduction target. If the insert information is added, the next image is reproduced in preference to the designated image. Displayed (Invention of Claim 15).

  According to the first aspect of the present invention (first invention), each time a shooting operation is performed, the current camera position is recorded and stored as the shooting position in association with the shot image. Is compared with the shooting position associated with the previous shooting image, and based on whether the change in position is greater than or equal to a predetermined value, it is determined whether or not the distance from the previous shooting position is far away. If it is far from the shooting position, the guidance for prompting the insert shooting is output, so that it is possible to guide the insert shooting that complements the distance gap. Therefore, for example, it is effective to be able to shoot every scene as it travels on a sightseeing trip, etc., or to remember to take a signboard of the sight-seeing area whenever you visit a new sight-seeing area. Shooting assistance guidance is possible.

  In this case, if the camera position at the time of switching to the shooting mode is compared with the previous shooting position (invention of claim 2), immediately after switching to the shooting mode to start shooting, the previous position is switched. It is possible to determine whether it is far from the shooting position. If the camera position at the time when the camera power is turned on in the state of switching to the shooting mode is compared with the previous shooting position (the invention according to claim 3), in order to temporarily stop shooting. Even if the camera power is turned off in the shooting mode, it is possible to determine whether the camera is turned off from the previous shooting position when the camera power is turned back on. Further, if the camera position at the time when the camera power is turned on is compared with the previous shooting position (the invention according to claim 4), the camera position is separated from the previous shooting position immediately after the camera power is turned on. Can be determined.

  According to the fifth aspect of the invention, in addition to having the same effect as that of the first aspect of the invention described above, in the state where the camera position at the time of guiding the insert shooting is temporarily stored and held as the guide position, the insert When the current camera position is not in the vicinity of the guide position as a result of comparing the current camera position and the guide position during the shooting operation after guiding the shooting, the guidance for prompting the insert shooting is output again. Therefore, it is possible to reliably prevent missed and missed guidance.

  According to the seventh aspect of the present invention (second invention), each time a shooting operation is performed, the current time and the previous time are recorded and stored as the shooting time in association with the shot image. Compare with the shooting time associated with the shot image, and determine whether the time change from the previous shooting based on whether the time change is more than a predetermined value, Since the guidance for prompting the insert shooting is output when the time is away from the camera, it is possible to guide the insert shooting that complements the time gap. Therefore, for example, it is possible to shoot every scene as time passes in a sightseeing trip, etc. Shooting assistance guidance is possible.

  In this case, if the current time at the time of switching to the shooting mode is compared with the previous shooting time (invention of claim 8), the previous time immediately after switching to the shooting mode to start shooting. It is possible to determine whether the time is away from the time of shooting. In addition, if the current time when the camera power is turned on and the previous shooting time are compared in the state of switching to the shooting mode (the invention according to claim 9), in order to temporarily stop shooting. Even if the camera power is turned off in the shooting mode, it is possible to determine whether the camera power is turned off from the previous shooting when the camera power is turned on. Further, if the current time when the camera power is turned on is compared with the previous shooting time (the invention according to claim 10), the time is separated from the previous shooting immediately after the camera power is turned on. Can be determined.

For example, if you take a picture of a park and then take an indoor shot, The indoor image can be played after playing the insert image that captures the signboard or the exterior of the hall, and editing work that changes the order of the stored shadow images must be done. , It is possible to image reproduction in a natural connection.

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 a digital camera in this embodiment.
This digital camera is a portable camera that can receive radio waves from a satellite / terrestrial positioning system (GPS) and acquire its current position (camera position). This is a still camera that can shoot movies. This digital camera is provided with a photographing assistance guide function for outputting guidance for prompting the photographer to photograph. This auxiliary shooting guidance function displays guidance for insert-cut shooting in order to compensate for the distance gap when distanced from the previous shooting position, or when timed away from the previous shooting time. In addition, it is a function for guiding and displaying the shooting of the insert cut in order to complement the time interval.
Before detailed description of the features of this embodiment, the hardware configuration of this embodiment will be described below.

  The CPU 1 is a central processing unit that controls the overall operation of the digital camera in accordance with the operating system and various application software in the storage unit 2. The storage unit 2 is a fixed memory such as a ROM or a hard disk, and has a program storage area and a data storage area. An application program for realizing the present embodiment is stored in the program storage area in the storage unit 2 in accordance with operation procedures shown in FIGS. 2 and 3 described later. The program and data in the storage unit 2 are loaded into the work memory 3 as needed, or the data in the work memory 3 is saved in the storage unit 2. The recording medium 4 is a detachable memory such as a DVD, and exchanges programs, image data, and the like with the storage unit 2 or the work memory 3.

On the other hand, an operation unit 5, a display unit 6, a camera photographing unit 7, and a GPS reception positioning unit 8 that are input / output peripheral devices are connected to the CPU 1 via a bus line. The operation control of these input / output devices is performed.
The operation unit 5 includes a shutter button ST, a mode button MD for switching to a shooting mode / reproduction mode, various function buttons, and the like, and operation signals thereof are given to the CPU 1. The display unit 6 is, for example, a liquid crystal display unit with a touch panel, and is used as a monitor screen / finder screen / image reproduction screen.

  The camera photographing unit 7 includes a photographing lens, a lens / mirror block such as a mirror, an image pickup device such as a CCD image sensor, a drive system thereof, and the like. The CPU 1 adjusts and controls the optical zoom function, or performs autofocusing. The CPU 1 controls the drive control, shutter drive control, exposure, and the like. The CPU 1 captures the captured image via the image memory 9 and records and saves it on the recording medium 4. The GPS reception positioning unit 8 receives a radio wave from GPS and acquires its current position (camera position). The CPU 1 acquires the current position from the GPS reception positioning unit 8 every time a shooting operation is performed. In addition, the current time is obtained from a clock unit (not shown), and the current position is added to the photographed image as information indicating the photographing position and the current time as information indicative of the photographing time, and is recorded and saved. That is, the shooting position and the shooting time are added to each shot image together with the file name.

  In a state in which the mode is switched to the shooting mode by operating the mode button MD, the CPU 1 acquires the current position from the GPS reception positioning unit 8 and adds it to the previous shot image (the last image shot last). By reading out the shooting position and comparing it with the current position, it is determined whether or not the position change is a distance from the previous shooting position based on whether or not the change in position is a predetermined value (for example, 1 km) or more. If it is far from the shooting position, guidance for prompting shooting of the insert cut is displayed and output. Similarly, in the shooting mode, the CPU 1 acquires the current time from the clock unit, reads out the shooting time added to the previous shot image, and compares it with the current time so that the time change is a predetermined value (for example, (1 hour) or more, it is determined whether or not it is time-separated from the previous shooting position, and if it is time-separated from the previous shooting position, guidance for prompting the insert cut is displayed. I am trying to output.

  Next, the operation concept of the digital camera 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. Moreover, the operation | movement according to the above-mentioned program code transmitted via the transmission medium can also be performed sequentially. 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.

2 and 3 are flowcharts showing the camera operation that is started when the camera power is turned on.
First, when the camera power supply is turned on, the CPU 1 determines the current operation mode and checks whether it is a shooting mode or a playback mode (step A1 in FIG. 2). If the playback mode is set, the process proceeds to step A12. If the shooting mode is set, the current position is acquired from the GPS reception positioning unit 8 (step A2), and the previous captured image is displayed. After reading the added “shooting position” and “shooting time” (step A3), by comparing the current position with the shooting position (step A4), whether the position change is more than 1 km away, that is, It is determined whether or not the position has been moved by 1 km or more from the previously photographed position (step A5). In this case, if it is 1 km or more away from the previous shooting position, the shooting guide for the insert cut relating to the place is displayed and output (step A6). Here, FIG. 4 is a diagram showing a shooting guidance screen for the insert cut regarding the place. On this guidance screen, a guidance sentence indicating that the place has moved considerably since the previous photographing and a guidance sentence prompting the insert photographing to complement this distance are displayed. In addition to such a guide display, an alarm sound that prompts insert shooting may be generated and output.

  On the other hand, if it is not 1 km or more away from the previous shooting position (NO in step A5), by comparing the current time with the previous shooting time (step A9), the time change is one hour or more, that is, the previous time It is determined whether or not one hour or more has elapsed since the time of shooting (step A10). In this case, if one hour or more has elapsed since the last shooting, an insert cut shooting guide related to the time is displayed and output (step A11). FIG. 5 is a diagram showing a shooting guidance screen for insert cuts relating to time. On this guidance screen, a guidance message indicating that a considerable amount of time has passed since the previous shooting and a guidance message prompting insert shooting in order to complement this time interval are displayed. In addition to such a guide display, an alarm sound that prompts insert shooting may be generated and output.

  After the insertion cut shooting guidance is displayed and output in this way, a guided flag (not shown) is set to indicate that it has been guided (step A7), and the current position and current time are displayed when the guide is displayed. Are temporarily stored as “guide position” and “guide time” (step A8). Then, the process proceeds to step A20 in FIG. 3 and waits until any operation is performed in a state where the monitor image is acquired and displayed (step A21). Here, when the shutter button ST is operated (YES in step A22), an image photographed in response to this is acquired (step A23), and the current position and current time are acquired (step A24). The current position and the current time are added to the photographed image as a “photographing position” and a “photographing time”, and are recorded and saved (step A25).

  Then, it is checked whether or not the above-described guided flag is set (step A26). If the guided flag is not set, the process returns to step A20 in FIG. 2, and the shooting conditions for the insert cut are checked as described above. When the guided flag is set (YES in step A26 in FIG. 3), the above-mentioned “guide position” is read, and the current position is compared with the guide position, so that the current position is 100 m or more from the guide position. It is checked whether they are separated (step A28). Here, if the current position is 100 m or more away from the guide position, the insert cut photographing guide relating to the place shown in FIG. 4 is output again (step A29), and the process returns to step A2. Therefore, when the guided flag is set and the distance from the guide position is 100 m or more, the shooting guide relating to the location is displayed again each time the shutter operation is performed.

  If the current position is less than 100 m in radius with respect to the guide position and is in the vicinity of the guide position (NO in step A28), the above “guide time” is read and the current time is compared with the guide time. (Step A30), it is checked whether 10 minutes or more have passed since the guide time (Step A31). If 10 minutes or more have passed, the shooting guide of the insert cut relating to the time shown in FIG. Step A), returning to step A20. Therefore, if the guided flag is set and if 10 minutes or more have elapsed from the guide time, the shooting guide relating to the time is displayed again each time the shutter operation is performed.

On the other hand, if the current position is in the vicinity of the guide position (NO in step A28) and 10 minutes before the guide time has elapsed (NO in step A31), the shooting according to the current shutter operation is performed by the insert cut. Assuming that shooting is performed, the process proceeds to step A33, the guided flag is reset, and then the process returns to step A20.
When an operation other than the shutter button ST is performed, that is, when the mode button MD is operated (YES in step A34), the shooting mode is canceled and the playback mode is switched (step A35). The process proceeds to step A12 in FIG. 2, but in the shooting mode, when any other button is operated (NO in step A34), the process corresponding to the operation button is executed (step A36), and then the process returns to step A20.

  Now, in the state switched to the reproduction mode, a captured image arbitrarily designated as a reproduction target is read out and displayed (step A12 in FIG. 2). Then, in any operation waiting state (step A13), when the mode button MD is operated (YES in step A14), after canceling the reproduction mode and switching to the photographing mode (step A15), the above-described step A2 Move on. In the playback mode, if any other button is operated (NO in step A14), the process corresponding to the operation button is executed (step A16), and then the process returns to step A13 to wait for the operation.

  As described above, in the first embodiment, the CPU 1 records and saves the current position acquired from the GPS reception positioning unit 8 as the shooting position in association with the shot image every time the shutter button ST is operated. , The current position acquired from the GPS reception positioning unit 8 is compared with the shooting position associated with the previous shooting image, and the distance from the previous shooting position is determined based on whether the change in position is 1 km or more. If it is far away from the previous shooting position, the guidance for prompting the insert shooting is displayed and output, so the insert shooting that compensates for the distance gap is guided. Can do. Therefore, for example, it is possible to provide effective shooting assistance guidance, such as being able to shoot every scene uniformly as it travels on a sightseeing trip or the like.

  In addition, the CPU 1 associates the current time with the previous photographed image in a state where the current time acquired from the clock unit every time the shutter button ST is operated is recorded and saved as the photographing time in association with the photographed image. Compared to the current shooting time, and based on whether the time change has passed for more than one hour, it is determined whether or not the time has departed from the previous shooting time, Since the guidance for prompting the insert shooting is displayed when the user leaves, the insert shooting can be guided to complement the time gap. Therefore, for example, effective shooting assistance guidance is possible, such as being able to shoot every scene uniformly over time in a sightseeing trip or the like.

  In this case, since the CPU 1 compares the current position / current time at the time of switching to the shooting mode with the previous shooting position / shooting time, the CPU 1 immediately before switching to the shooting mode to start shooting. It is possible to discriminate whether it is far from the shooting position / shooting time in terms of distance / time. In addition, the current position / current time when the camera power is turned on in the state of switching to the shooting mode is compared with the previous / shooting position / shooting time. Even if the camera power is turned off while in the mode, it can be determined whether the camera power is turned off and whether the distance from the previous shooting position / shooting time is away from the previous shooting position / time. Also, since the current position / current time at the time when the camera power is turned on is compared with the previous shooting position / shooting time, immediately after the camera power is turned on, the distance / It is possible to determine whether they are separated in time.

  Further, the CPU 1 temporarily stores the current position / current time and the guide position / guide time during the shooting operation after guiding the insert shooting in a state where the guide position / guide time when the insert shooting is guided is temporarily stored. As a result of the comparison, when the current position is not near the guide position or when the current time is not near the guide time, the guidance for prompting the insert shooting is displayed again, so that it is possible to reliably prevent missed guidance. it can.

  Although not particularly mentioned in the first embodiment described above, the movement distance varies greatly depending on whether it is walking movement or vehicle movement. Therefore, by calculating the movement speed based on the movement distance per unit time, Whether it is a walking movement or a vehicle movement is determined, and if it is a walking movement, an imaging assistance guide function for guiding insert imaging may be activated. In addition, when a new recording medium in which a photographed image is not recorded is loaded, the previous photographed image does not exist, but at such an initial point, the insert photographing may be guided unconditionally. Good.

In the first embodiment described above, “1 km or more” and “1 hour or more” are exemplified as the reference values for determining whether the distance / time is away from the previous shooting position / time. The photographer may set an arbitrary value.
Further, in the first embodiment described above, whether or not the distance from the previous shooting position / shooting time is separated in terms of distance / time is determined individually, but it is determined by combining them. Also good. For example, when the vehicle is moving, the insert shooting may be guided when it is 1 km or more away from the previous shooting position and one hour or more has passed since the previous shooting time. In addition, if one hour has passed since the previous shooting time and 100 m or more away from the previous shooting position, and if the insert shooting is guided, it is a case where it stays in one place. , It can be excluded from guidance.

  On the other hand, a recording medium (for example, a CD-ROM, a flexible disk, a RAM card, etc.) on which program codes for executing the above-described units are recorded may be provided to the computer. That is, a recording medium having a program code that can be read by a computer, the function of monitoring the current camera position while acquiring position information, and the acquired position information as the shooting position each time a shooting operation is performed In the state of recording and saving in association with the captured image, the acquired current camera position is compared with the imaging position associated with the previous captured image, and whether the position change is equal to or greater than a predetermined value. The function to determine whether or not the distance from the previous shooting position is based on the distance, and when it is determined that the distance from the previous shooting position is distance, insert to complement the distance You may make it provide the computer-readable recording medium which recorded the program for implement | achieving the function which outputs the guidance which accelerate | urge | promotes imaging | photography.

In addition, the present invention is a recording medium having a computer-readable program code, in which the current time and the previous time are recorded and stored in association with the photographed image as the photographing time every time a photographing operation is performed. A function that compares the shooting time associated with the captured image and determines whether the time change from the previous shooting is based on whether or not the time change is a predetermined value or more, Can be read by a computer that records a program for realizing a function to output guidance for prompting insert shooting to compensate for the time gap when it is determined that the time is away from the time of shooting A recording medium may be provided.
(Example 2)

A second embodiment of the present invention will be described below with reference to FIGS.
In the first embodiment described above, the insert shooting is guided when the distance / time is away from the previous shooting position / time, but in the second embodiment, the previous shooting is guided. When the current shooting environment changes from the shooting environment, insert shooting that guides the change in the shooting environment 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. .

6 and 7 are flowcharts showing the camera operation that is started when the camera power is turned on in the second embodiment.
First, when the camera power supply is turned on, the CPU 1 determines the current operation mode and checks whether it is a shooting mode or a playback mode (step B1). If the playback mode is set, the process proceeds to step B20 in FIG. 7. If the shooting mode is set, the process waits (step B2). Here, it is determined whether the shutter button ST has been operated (step B3) or the mode button MD has been operated (step B4). If the mode button MD has been operated, the shooting mode is canceled and the playback mode is set. After switching (step B6), the process proceeds to step B20 in FIG. 7, but when other buttons are operated in the shooting mode (NO in step B4), the process corresponding to the operation button is executed (step S4). B5), the process returns to step B2 and waits for an operation.

  If the shutter button ST is operated (YES in step B3), the photographed image is acquired and recorded and saved (step B7), and then the presence / absence of a photographed image photographed last time is checked (step B8). In this case, at the first time when a new recording medium in which no photographed image is recorded is loaded, the previous photographed image does not exist, so the process proceeds to step B12 to display and output a guide for prompting insert photography, which will be described later. If the previous captured image exists, the process proceeds to step B9, and the brightness level of the portion illuminated by light around the subject is detected by analyzing the captured image captured this time. In this case, it is detected whether it is brighter or darker than a predetermined reference level.

  Then, after detecting the brightness level by reading the previously captured image and performing image analysis, the brightness levels of the current captured image and the previous captured image are compared (step B10). It is stepped whether or not the brightness level has changed greatly (step B11). In this case, it is possible to determine whether the indoor photographing is changed to the outdoor photographing or the outdoor photographing is changed to the indoor photographing depending on the change in the brightness level. That is, if the current shot image is bright and the previous shot image is dark, it is determined that the camera has shifted from outdoor shooting to indoor shooting. Conversely, if the current shot image is dark and the previous shot image is bright, indoor shooting is performed. Judged to have shifted to outdoor photography. That is, it is determined that the shooting environment has changed significantly.

  If the change in the brightness level of the current and previous captured images is small and the shooting environment does not change significantly (NO in step B11), that is, if both images are bright or dark, the process proceeds to step B2 described above. If the brightness of the current and previous captured images has changed significantly (YES in step B11), a guide for prompting insert-cut imaging due to environmental changes is displayed and output (step B12). On this guidance screen, a guidance sentence indicating that the photographing environment has changed significantly and a guidance sentence prompting insert photographing to complement this environmental change are displayed. Here, the camera enters a state of waiting for an instruction from the photographer, and after receiving an OK instruction for insert photography from the photographer (YES in step B13), if a shutter operation is performed (YES in step B14), the camera responds to the shutter operation. Then, the captured image is acquired and recorded and saved (step B15), and an insert cut flag is added to the captured image to indicate that it is an insert image (step B16). And it returns to step B2 and will be in the operation waiting state. Hereinafter, in the shooting mode, the above-described operation is repeated every time a shutter operation is performed.

  FIG. 8 exemplifies a state in which each captured image captured in this way is recorded and stored in the order of capturing, and the second captured image is captured with respect to the first captured image. Since the environment has changed greatly, for example, when shooting from indoor shooting to outdoor shooting or from outdoor shooting to indoor shooting, the second image shot in response to the guide display prompting insert cut shooting is set to the insert cut flag. Is set. Similarly, the sixth image captured in response to the guide display for prompting the insert-cut shooting is also the case where the shooting environment of the sixth shot image is greatly changed with respect to the fifth shot image. Is set with an insert cut flag.

  On the other hand, when the shooting mode is switched to the playback mode, the process proceeds to step B20 in FIG. 7, and the image captured immediately before is read out and displayed, and then the operation is waited (step B21). Here, it is determined whether or not the button for instructing slide playback has been operated (step B22) or the mode button MD has been operated (step B23). If the mode button MD has been operated, the playback mode is canceled. After switching to the shooting mode (step B25), the process returns to step B2 in FIG. 6. However, when other buttons are operated in the playback mode (NO in step B23), processing corresponding to the operation button (for example, After executing the process of selecting and specifying the reproduction target (step B24), the process returns to step B21 and waits for an operation.

Now, when the button for instructing slide playback is operated (YES in step B22), after specifying the head image among a plurality of images selected as playback targets (step B26), Next, an image recorded and stored is accessed to check for the presence of an insert cut flag (step B27). Now, in the example of FIG. 8, in the state in which the first image is designated, the next second image has an insert cut flag added thereto. Therefore, the presence of the flag is detected in step B28, and step B29. Then, the next image (second image) is read out and displayed for priority over the designated image (first image).
FIG. 9 shows the reproduction order of each captured image shown in FIG. 8, and the second image is displayed before the first image. Here, in the waiting state for the operation of the image advance button (step B30), when the advance button is operated, the designated image (first image) is read and displayed instead of the next image (second image). (Step B31).

  Here, in the state where the designated image (first image) is displayed, when the feed button is further operated (step B32), next to the flag-added image (second image) preferentially displayed this time. (Third image) is designated (step B33), and whether the insert cut flag is added to the next image (fourth image) after this designated image is checked (step B27). Since no flag is added to the image (NO in step B28), the process proceeds to step B34, where the designated image (third image) is read out and displayed. Here, when the feed button is operated (step B35), after specifying the next image (fourth image) (step B36), the process returns to step B27 and the above operation is repeated. In this case, when the fifth image is designated, since the insert cut flag is added to the next sixth image, as shown in FIG. 9, the sixth image is higher than the fifth image. Is displayed first. Thereafter, the same operation is repeated until all the images selected as playback targets are displayed.

  As described above, in the second embodiment, the CPU 1 determines whether or not the shooting environment has changed by comparing the brightness level of the shot image shot this time with the previously shot shot image. If the environment has changed, the guidance prompting for insert shooting is displayed and output, so it is possible to guide insert shooting that complements changes in the shooting environment, and every scene is shot every time the shooting environment changes. This makes it possible to provide effective shooting assistance guidance. In this case, by comparing the brightness level of the captured image captured this time with the previously captured image, it is determined whether it has changed from indoor shooting to outdoor shooting or from outdoor shooting to indoor shooting. Therefore, for example, when entering a memorial hall, it is possible to take an image of the signboard or the exterior of the building.

  In addition, in a state where an insert cut flag indicating an insert image is added to a photographed image photographed after guiding the insert photographing, a plurality of photographed images are designated and reproduced and displayed at the time of image reproduction. At this time, it is checked whether or not the insert cut flag is added to the next image positioned next to the designated image designated as the reproduction target. If the insert cut flag is added, the next image is given priority over the designated image. For example, when shooting a park and then shooting indoors in a memorial hall, play an indoor image after playing an insert image that captures the signboard or exterior of the memorial hall. The image can be reproduced with natural connection without performing an editing operation for changing the order of the stored shadow images.

  In the second embodiment described above, it is determined whether the shooting mode changes from indoor shooting to outdoor shooting or from outdoor shooting to indoor shooting. If you decide to detect dawn from night, you can shoot sunset insert images and morning sun insert images, suddenly shift from daytime shooting images to nighttime shooting, or from nighttime shooting to daytime shooting. There is no such thing as moving, and it is possible to take pictures that naturally connect the changes of time.

  Further, a computer-readable recording medium having a program code, a function for determining whether or not the shooting environment has changed by comparing the captured image captured this time with the previously captured image, Provided a computer-readable recording medium storing a program for realizing a function for outputting guidance for prompting an insert shooting in order to complement the change in the shooting environment when it is determined that the shooting environment has changed. You may make it do.
