Abstract

PROBLEM TO BE SOLVED: To provide a photographing device that can allow a user to notice an insufficiency even when there is the insufficiency in a photographing preparation work to be conducted before housing a photographing device in a sealed container.SOLUTION: In a video camcorder 100, whether it is shifted to an underwater mode or an on-the-water mode is determined. If it is determined to be shifted either of the modes, it is checked whether the photographing preparation work to be conducted before housing the video camcorder in a waterproof case is conducted or not.

Description

  The present invention relates to an imaging apparatus that captures a moving image or a still image, and more particularly to an imaging apparatus that can be used in a waterproof case, a control method therefor, a program, and a recording medium.

  Conventional digital cameras and video camcorders have a function called a scene mode that stores exposure programs and settings that are optimal for shooting specific scenes such as night views and sports, and calls them according to the shooting scene. is there. One of the variations of this scene mode is a setting suitable for underwater shooting (hereinafter referred to as “underwater mode”).

  In underwater photography, water mediates between the lens and the subject, and the white balance and exposure characteristics differ greatly from the air depending on the optical characteristics of the water. Therefore, in the underwater mode, settings for correcting optical characteristics peculiar to underwater are made.

  When performing underwater photography, it is necessary to store the photographing apparatus in an airtight container other than the photographing apparatus itself having a waterproof structure. Such a sealed container is generally called a “waterproof case” or “underwater pack”.

  When shooting underwater using a waterproof case, in order to improve waterproof performance, grease is applied to the gap between the contact points of the lid with an open / close structure, or condensation occurs in the waterproof case due to a sudden change in ambient temperature It is also necessary to store the hygroscopic material so that it does not. Since it takes time for any work to be in a state where a sufficient effect is obtained, it is a situation to avoid opening and closing the lid of the waterproof case again.

  However, if you have forgotten to change the scene mode of the photographic device to the underwater mode after storing the photographic device in the waterproof case and performing the waterproofing process described above, re-attach the cover of the waterproof case again. It must be opened and closed and waterproofed. This places an unnecessary burden on the user.

  In order to avoid the above situation, a technique has been proposed in which the scene mode is automatically changed to the underwater mode by detecting that the photographing apparatus is housed in a waterproof case (for example, patents). Reference 1). It is also possible to change the scene mode of the photographing apparatus by performing remote control by wired communication or wireless communication without opening / closing the waterproof case.

JP 2006-194984 A

  However, in the above conventional example, the range in which the setting can be changed by software control triggered by the result of detecting the storage in the waterproof case or the communication information from the remote control or the like is the target, so the following problems There is. That is, the shooting preparation work is not limited to setting change by software control including scene mode setting. For example, there is an operation that can be performed only by directly touching the photographing apparatus, such as attachment of a battery having a sufficient remaining charge amount or attachment of a recording medium. These operations cannot be changed after the waterproof case lid is closed unless the lid is opened again.

  As described above, there is a problem in the conventional photographing apparatus if there is no method for notifying the user of the deficiency when the photographing preparation work to be performed before the photographing apparatus is housed in the waterproof case.

  The present invention has been made in view of the above problems, and even if there is a deficiency in the shooting preparation work that should be performed before the imaging device is stored in the sealed container, the technology can make the user aware of the deficiency. The purpose is to provide.

  In order to achieve the above object, the present invention provides a communication device for communicating with an external operation device for operating the photographing device from outside by wired or wireless, and a special environment in which the photographing device is housed in a sealed container. In a photographing apparatus having a photographing mode for performing photographing with a determination unit for determining whether or not the mode has been shifted to the photographing mode, and when the determination unit determines that the mode has been shifted to the photographing mode, It is characterized by comprising confirmation means for confirming whether or not photographing preparation work to be performed before the photographing apparatus is stored in the sealed container, and notification means for notifying the user of the confirmation result by the confirmation means.

  According to the present invention, even if there is a deficiency in the shooting preparation work that should be done before the imaging device is stored in the sealed container, the user can be made aware of the deficiency.

It is a figure which shows schematic structure of the video camcorder which is an example of the imaging device which concerns on embodiment of this invention. It is a figure which shows an example of the screen displayed on the display of a video camcorder, (a) is at the time of normal imaging | photography, (b) is immediately after transfering to underwater mode. It is a flowchart showing the operation | movement process of the video camcorder after power supply ON.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a diagram showing a schematic configuration of a video camcorder that is an example of a photographing apparatus according to an embodiment of the present invention.

  In FIG. 1, the video camcorder 100 includes a CPU (Central Processing Unit) 101, a program ROM 102, a memory 103, a display 104, and an operation unit 105 connected to each other via an internal bus 111. The video camcorder 100 also includes a recording medium drive 106, a communication interface (I / F) 107, and a battery 108. Only the portions related to the present invention are described in the illustrated example, and other portions such as the photographing lens and the CCD are omitted.

  The CPU 101 is an arithmetic processing device that controls the operation of the video camcorder 100. The CPU 101 receives an instruction from the user via the operation unit 105 or the like, executes various programs to be described later, and controls display on the display 104. In the program ROM 102, data and operation processing procedures of the CPU 101 (for example, a program for starting up a video camcorder, basic input / output processing, and each processing of the present invention to be described later) are recorded. The memory 103 is used as a work area for the CPU 101.

  The display 104 is a display unit for providing a graphic user interface (GUI). The display 104 displays images and display items to be described later. The operation unit 105 is a user interface for receiving an instruction from the user, and a switch, a dial, and the like are arranged. The user can change various settings of the video camcorder 100 by operating the operation unit 105. For example, the operation unit 105 can perform operations such as start / stop, playback, pause, fast forward, rewind, slow, frame advance, and power on / off. The operation unit 105 can set a scene mode and a shooting mode for the video camcorder 100.

  The recording medium drive 106 is an apparatus configured such that a recording medium 109 composed of a card-shaped flash memory can be inserted and removed. The recording medium drive 106 reads data from the loaded recording medium 109 and writes data to the recording medium 109. Note that the data described below includes still image data and moving image data unless otherwise specified.

  The recording medium drive 106 includes a sensor for detecting whether or not the recording medium 109 is attached. Note that the type and structure of the sensor for detecting whether or not the recording medium 109 is attached may be any type. The detection result by this sensor is notified to the CPU 101 via the internal bus 111.

  Further, the recording medium drive 106 has a function of detecting the remaining capacity of the loaded recording medium 109 and notifying the CPU 101 of it.

  The I / F 107 performs wired communication or wireless communication with the external operation device 110 outside the video camcorder 100. In the illustrated example, it is assumed that wireless communication is performed between the I / F 107 and the external operation device. In the case of wired communication, the I / F 107 and the external operation device 110 are connected by a cable or the like.

  The external operation device 110 is provided with operation buttons such as start / stop, playback, pause, fast forward, rewind, slow, frame advance, and power ON / OFF. Note that the types of operation buttons are not limited to these. The operation buttons provided in the external operation device 110 are also arranged in the operation unit 105, but the types of operation buttons are limited. The external operation device 110 has a function of transmitting the content operated by the user as a command to the I / F 107 by wired communication or wireless communication. The I / F 107 notifies the CPU 101 of the received command via the internal bus 111.

  The battery 108 is a rechargeable battery such as a lithium ion battery, and supplies power to each part in the video camcorder 100. Further, the battery 108 has a function of detecting the remaining amount of the battery by a charge capacity detection circuit (not shown) incorporated in the battery 108 and program processing by the CPU and notifying the CPU 101 of the detection result.

  Next, the underwater mode in the video camcorder 100 of FIG. 1 will be described. As described above, the underwater mode is a shooting mode for shooting in a special environment in which the video camcorder 100 is housed in a waterproof case.

  Since the video camcorder 100 in FIG. 1 does not have a waterproof structure, the user needs to store the video camcorder 100 in a waterproof case (sealed container) when performing underwater shooting. If the video camcorder 100 is housed in a waterproof case and directly touched before closing the cover, the necessary preparation for shooting is not performed, and the cover needs to be closed again after the case is opened and the work is performed. The following is a list of shooting preparations required for storing video camcorders in a waterproof case and the reasons for them.

(1) Confirmation of setting of underwater mode If the waterproof case is closed without setting the “underwater mode”, it is not possible to shoot with settings suitable for underwater shooting.

(2) Validity / invalidity setting of wireless (or wired) communication with external operation device 110 When the lid of the waterproof case is closed in a state where the validity / invalidity setting of wireless (or wired) communication is set to “invalid” The video camcorder 100 cannot be operated by the external operation device 110.

(3) Whether or not the recording medium 109 is attached If the lid of the waterproof case is closed when the recording medium 109 is not attached, it is necessary to open and close the lid again. Note that there is no problem when the video camcorder 100 has a built-in recording medium. The lid of the waterproof case needs to be opened and closed again.

(4) Confirmation of the remaining capacity of the recording medium 109 If the cover of the waterproof case is closed in a state where the recording capacity of the recording medium 109 is small (remaining capacity), the planned shooting cannot be performed sufficiently. In some cases, data recorded on the recording medium 109 must be erased. Therefore, it is necessary to open and close the waterproof case lid again.

(5) Confirmation of the remaining amount of the battery 108 If the waterproof case is closed without noticing that the remaining amount of the battery 108 is low, the initially possible shooting time is reduced, and sufficient shooting cannot be performed. Moreover, the battery itself may be significantly reduced from the remaining amount expected by the user due to deterioration of the battery itself or natural discharge due to being left for a long period of time. Therefore, it is necessary to open and close the waterproof case lid again.

(6) Confirmation of shooting mode setting If the setting of the video shooting mode / still image shooting mode can be set only with the operation unit 105, the lid needs to be opened and closed again if the waterproof case is closed without performing the necessary settings. There is.

  Next, an operation process when shooting in the underwater mode in the video camcorder 100 will be described with reference to FIGS.

  FIG. 2A is a diagram illustrating an example of a display screen displayed on the display 104 during normal shooting. FIG. 2B is a diagram illustrating an example of a display screen displayed on the display 104 immediately after shifting from the normal shooting to the underwater mode. The normal shooting means a normal state in which no scene mode or the like is set.

  2A, a scene mode icon 201, a shooting mode icon 202, a battery remaining amount icon 203, and a recording medium remaining capacity icon 204 are displayed on the display 104 in the normal state.

  The scene mode icon 201 is an icon display for allowing the user to recognize the current scene mode setting. When the scene mode setting is changed on the operation unit 105, the icon display shape and state are changed. The shooting mode icon 202 is an icon display for allowing the user to recognize the current shooting mode setting. When the setting is changed to either the moving image shooting mode or the still image shooting mode, the display shape and state of the icon change. Is done.

  The battery remaining amount icon 203 is an icon display for allowing the user to recognize the remaining amount of the battery 108. The recording medium remaining capacity icon 204 is an icon display for allowing the user to recognize the remaining capacity of the recording medium 109 loaded in the recording medium drive 106.

  On the display 104 immediately after shifting to the underwater mode in FIG. 2B, an underwater mode icon 205, a remote control invalid icon 206, a recording medium unusable icon 207, and a recording medium shortage warning icon 208 are displayed. Yes. In addition, a battery remaining amount warning icon 209 and a shooting mode warning icon 210 are displayed on the display 104. These icon displays will be described later.

  FIG. 3 is a flowchart showing the operation process of the video camcorder 100 after the power is turned on. In this process, the CPU 101 reads the control program from the program ROM 102 and executes it.

  When a user performs underwater shooting, a procedure is often employed in which the scene mode of the video camcorder 100 is changed to “underwater mode” and then the apparatus is housed in a waterproof case and the lid is closed. At this time, the user is expected to see the display screen of the display 104 in order to confirm that the video camcorder 100 has shifted to the underwater mode. In view of this, in the video camcorder 100, whether or not the shooting preparation work is properly performed when the mode is shifted to the underwater mode so that the user can perform the shooting preparation work described above before the cover is closed in the waterproof case. Is displayed on the display 104 to that effect.

  In FIG. 3, first, the CPU 101 determines whether or not the scene mode is set to the underwater mode (step S311). When the CPU 101 detects an operation for changing the setting to the underwater mode on the operation unit 105, the CPU 101 changes the display of the scene mode icon 201 to the display of the underwater mode icon 205 (step S313). As another embodiment, when the use of a waterproof case is assumed as in the underwater mode, and there is a “water mode” setting that is slightly different from the underwater mode, the processing is as follows. An operation may be performed. That is, when an operation for changing the setting to the water mode is detected, the display of the scene mode icon 201 is changed to the display of the water mode icon (not shown) (steps S312 and S313). If the setting of the water mode is not provided, step S312 can be omitted.

  Next, the CPU 101 confirms whether the communication setting with the external operation device 110 is invalid (step S314). When the CPU 101 detects that the communication setting with the external operation device 110 is “invalid”, the CPU 101 determines to display the remote control invalid icon 206 shown in FIG. The actual icon display is performed in a warning icon display process in step S319 described later.

  Next, the CPU 101 confirms whether or not the recording medium 109 is loaded in the recording medium drive 106 and data can be written (step S315). When the CPU 101 detects a non-attached state of the recording medium 109 or determines that data writing is impossible even if the recording medium 109 is attached, the CPU 101 determines to display the unusable icon 207 of the recording medium.

  Note that an icon having the same meaning can be displayed even in a normal state other than the underwater mode. However, when a recording medium incorporated in the video camcorder 100 can be selected as a recording destination, it is a useful technique not to display the recording medium 109 in order to reduce redundancy due to displaying the non-selected medium. Conceivable. In this case, since information regarding the recording medium 109 is not displayed on the display 104, the importance of displaying an icon in step S319 increases according to the result of step S315.

  Further, even in the normal state, when the non-mounting state of the recording medium 109 is detected, or when it is determined that data writing is impossible even when the recording medium 109 is mounted, the recording medium unusable icon 207 is displayed. You may comprise so that it may display. Even in this case, if it is determined again in the non-attached state or the data write-in disabled state in step S315, a display for alerting the user is performed again in step S319 described later. As a display that alerts the user again, for example, the unusable icon 207 that has already been displayed may be blinked or the display color may be changed.

  Next, the CPU 101 confirms whether the remaining capacity of the recording medium 109 is appropriate (step S316). The following two conditions are conceivable as conditions for the remaining capacity of the recording medium 109 to be appropriate.

  The first condition is that the remaining amount of charge of the battery 108 attached to the video camcorder 100 is sufficient for the recording amount that can be recorded on the current recording medium 109. Specifically, in the highest moving image recording mode (generally expressed by a bit rate) that can be set by the video camcorder 100, the recording amount per unit time on the recording medium 109 is the maximum.

  Therefore, using the current remaining battery level, the first recordable time when recording on the recording medium in the highest quality recording mode that can be set by the camcorder, and the remaining capacity of the recording medium in the highest quality recording mode. Compared with the second recordable time when data is recorded until no longer exists. If the first recordable time is expected to be longer than the second recordable time, it is determined that the remaining capacity of the recording medium 109 is not appropriate. In this case, since there is a possibility that additional recording cannot be performed on the recording medium 109 unless the recorded data is erased before the remaining amount of the battery 108 is exhausted, the remaining capacity of the recording medium is used to alert the user. It is determined that the shortage warning icon 208 is displayed.

  Note that the power consumption increases as the moving image recording mode is increased, so that the time until the remaining amount of the battery 108 is exhausted is slightly shortened, but the increase in the use capacity of the recording medium is more remarkable. Therefore, even if the moving image recording mode set by the user at that time is different from the highest quality moving image recording mode, the recordable time for recording in the highest quality moving image recording mode that can be set by the photographing device is determined. It is desirable to use it.

  When displaying the remaining capacity shortage warning icon 208 of the recording medium on the screen, there is a concern that the influence will be larger than the second condition described later. Therefore, using red or the like as the icon display color can prompt the user to call attention.

  Next, the second condition is that the recording amount that can be recorded on the current recording medium 109 is sufficient with respect to the maximum charging amount of the battery 108 attached to the video camcorder 100. Specifically, similarly to the first condition described above, the recording amount per unit time on the recording medium 109 is maximum in the highest quality moving image recording mode that can be set by the video camcorder 100. The highest quality moving image recording mode is the recording mode that consumes the most battery power. Therefore, the third recordable time when recording on the recording medium 109 in the highest quality recording mode using the battery 108 in the maximum charge state, and until the remaining capacity of the recording medium 109 runs out in the highest quality recording mode. The second recordable time when recording is compared. If the third recordable time is expected to be longer than the second recordable time, it is determined that the remaining capacity of the recording medium 109 is not appropriate. When considering that the battery 108 is fully charged, as in the first condition, additional data recording is performed unless the data recorded on the recording medium 109 is erased before the remaining amount of the battery 108 is exhausted. If there is a risk of failure, do the following: That is, in order to alert the user in step S319, which will be described later, it is determined to display the recording medium shortage warning icon 208.

  When the storage medium shortage warning icon 208 is displayed on the screen, since the severity is considered to be lower than the first condition described above, the icon display color is differentiated by using yellow or the like. It can be performed.

  Further, when the remaining capacity shortage warning icon 208 of the recording medium is displayed, a capacity value that is insufficient when recording on the recording medium 109 in the highest quality moving image recording mode is calculated, and the capacity value is displayed as an icon. It may be configured. This helps the user determine whether or not to replace the recording medium 109 and is useful.

  It is simply determined that the recording medium shortage warning icon 208 is displayed when the recordable time that can be additionally recorded on the recording medium 109 is equal to or less than a predetermined threshold value with the current settings. May be. In this case, the threshold value is set lower than the threshold value when the remaining capacity shortage warning icon of the recording medium is displayed during normal shooting (during shooting other than underwater mode). This is because the recording medium cannot be easily replaced if it is housed in a waterproof case and the lid is closed, so that a warning must be issued at a stage with more margin than usual.

  Next, the CPU 101 confirms whether or not the remaining amount of the battery 108 is sufficient (step S317).

  As shown in FIG. 2A, the battery level icon 203 is displayed on the display 104 even during normal times. The remaining amount display of the battery remaining amount icon 203 is generally displayed in a classified manner according to the remaining amount ratio. For example, since the same icon is used for the icon display when the remaining amount is 80% and the icon display when the remaining amount is 100%, it is difficult for the user to determine the remaining amount of the battery 108. For example, even if there is a remaining amount of 80% or more, a display method is realized in which the remaining amount is noticed. Therefore, when the remaining amount is 80% and when the remaining amount is 100%, a second threshold value different from the first threshold value used when determining the display form of the battery remaining amount icon 203 in the normal state is used. A battery level warning icon 209 is displayed so that a different display is made. In this case, the battery level warning icon 209 is configured to be displayed faster in the underwater mode than in normal times (during normal shooting). For example, by setting the above-described threshold value to 95%, when the remaining amount is 90%, the battery remaining amount warning icon 209 can be displayed.

  In step S317, the CPU 101 calculates a fourth recordable time when recording until the remaining capacity of the recording medium runs out in the recording mode set in the camcorder. Further, a fifth recordable time when data is recorded until the remaining capacity of the recording medium runs out in the recording mode is calculated using the detected remaining battery level. Then, the fourth recordable time is compared with the fifth recordable time, and if the fourth recordable time is longer than the fifth recordable time, it is set as a warning target for insufficient battery power. This is because the user's usability is not good when the remaining battery level is used up faster than the remaining capacity of the current recording medium 109 is used up.

  Further, the CPU 101 calculates the sixth recordable time when recording on the recording medium 109 in the recording mode using the battery 108 in the maximum charge state, and calculates the fourth recordable time and the sixth recordable time. Compare As a result, when the fourth recordable time is shorter than the sixth recordable time, it is not set as a warning target for insufficient battery power. The reason for adding these conditions is as follows. That is, in recent years, the capacity of recording media has increased, and the maximum possible recording time with a fully charged battery is about 1 to 3 hours, but a recording medium of several tens GB can take several tens of hours. Is possible. When the remaining capacity of the recording medium has a sufficient margin, it is always a warning target in order to satisfy the above-mentioned “fifth recordable time <fourth recordable time”. The user can only be bothered because the above charging is not possible. Therefore, in the present embodiment, the above-described exception condition to be warned is set.

  Also, if the remaining battery capacity is likely to make it impossible to drive the video camcorder 100 sooner than the remaining capacity of the current recording medium 109 is used up, the remaining battery power warning icon 209 is displayed in a different manner from the previous example. It is also useful to display. The different modes mean those that can be identified by a difference in color scheme or shape. When the user notices this display, an opportunity to perform additional charging can be given.

  Note that since the capacity of the recording medium used in the photographing apparatus is very large, there is a high possibility that the icon will be displayed even if the remaining battery level is 100%. Therefore, when it is recognized that the remaining battery level is near 100%, the troublesome display can be reduced by providing a restriction that the remaining battery level warning icon 209 is not displayed.

  Next, the CPU 101 confirms whether the currently selected shooting mode is the moving image shooting mode (step S318).

  Some video camcorders in recent years have a function of generating a still image from one frame of a recorded moving image, so that a still image can be obtained even in the moving image shooting mode. However, a still image obtained in the moving image shooting mode and a still image obtained in the still image shooting mode differ in various settings such as the exposure program characteristics, and thus the obtained still images are different. On the other hand, it is very difficult to generate a moving image having a smooth connection from a plurality of still images taken at irregular intervals. There is no problem if the user has consciously selected the still image shooting mode, but it becomes a problem if the still image shooting mode is mistakenly stored in the waterproof case when shooting a moving image. Further, the external operation device 110 may not be able to switch between the moving image shooting mode / still image shooting mode. Therefore, when it is detected that the moving image cannot be recorded when the mode is changed to the underwater mode, the shooting mode warning icon 210 is determined to be displayed. Note that the shooting mode warning icon 210 shown in FIG. 2B means the still image shooting mode.

  The confirmation results in steps S314 to S318 described above are items that are determined to require attention to the user, and the CPU 101 displays an icon display suitable for the determination results in step S319. To do. Note that the icon display method in step S319 includes a method of displaying only those that meet the conditions when confirmed in steps S314 to S318, and a method of changing the color scheme and shape depending on whether the conditions match. Conceivable. For example, the icon display shown in FIG. 2B is the case where all the conditions in steps S314 to S318 are met in the former method. On the other hand, in the latter method, for example, those that match each condition are displayed in red, and those that do not match are displayed in green.

  Next, the CPU 101 performs icon display for a predetermined time set in advance, and after this has elapsed (YES in step S320), the CPU 101 ends the icon display (step S322). The predetermined time set in advance is a time sufficient for the user to grasp the display contents, or the display function is one of the purposes of the display 104 by continuing to display more than necessary. It is preferable that the time is such that it does not hinder. Specifically, about 5 seconds to 10 seconds is preferable.

  If the video camcorder 100 has a scene mode storage function, the process shown in FIG. 3 is performed each time the power is turned on / off repeatedly while the underwater mode is set. As a result, an icon as shown in FIG. 2B is displayed on the display 104 every time, which is annoying to the user. In some cases, the user already dives underwater and wants to perform a recording operation immediately. Thus, the icon display may be terminated when it is detected that some operation has been performed on the operation unit 105 (steps S321 and S322).

  When the series of processes described above is completed, the video camcorder 100 returns to the normal main routine process.

  According to the above-described embodiment, it is determined whether or not the mode has been changed to the underwater mode or the water mode, and when it is determined that the mode has been changed, the shooting preparation work to be performed before the video camcorder is stored in the waterproof case is performed. Confirm that it has been received and notify the user of the result. Thereby, even if there is a deficiency in the shooting preparation work to be done before the video camcorder 100 is stored in the waterproof case, the deficiency can be noticed by the user.

  In the above embodiment, the recording medium that can be inserted into and removed from the video camcorder has been described. However, the recording medium may be a recording medium fixed inside the video camcorder, or the video camcorder may be configured to include both of these. .

  Further, the video camcorder has been described as an example of the photographing apparatus according to the present embodiment. However, the video camcorder is not limited thereto, and may be a digital camera or an electronic device such as a mobile TV, a mobile phone, or a smartphone.

  Further, although a card-shaped flash memory has been described as an example of the recording medium 109, a magnetic tape, an optical disk, or the like may be used as long as the recording medium can write and read data.

  Although the present invention has been described in detail based on preferred embodiments thereof, the present invention is not limited to these specific embodiments, and various forms within the scope of the present invention are also included in the present invention. included.

  The present invention can also be realized by executing the following processing. That is, software (program) that realizes the functions of the above-described embodiments is supplied to a system or apparatus via a network or various storage media, and a computer (or CPU, MPU, or the like) of the system or apparatus reads the program. It is a process to be executed.
