  ADVANTAGE OF THE INVENTION According to this invention, the imaging device which a user can identify easily how many series of images image | photographed at the same diving spot was image | photographed by the time of the diving can be provided.

  Hereinafter, the present invention will be described through embodiments of the invention. However, the following embodiments do not limit the invention according to the scope of claims, and all combinations of features described in the embodiments are included. It is not necessarily essential for the solution of the invention.

  FIG. 1 shows an example of a usage environment of an imaging apparatus 100 according to an embodiment of the present invention. The imaging apparatus 100 captures an object and acquires an image according to an instruction from the user 190. The imaging device 100 determines whether the imaging device 100 is in water based on a signal from the underwater sensor unit 110 provided in the imaging device 100. When the imaging apparatus 100 detects that the camera has entered the water from the water, the imaging apparatus 100 stores an image captured in the water until it next rises on the water in a different directory from the image that has already been captured. Similarly, when the imaging apparatus 100 detects that the camera has entered the water from underwater, similarly, a directory different from an image obtained by imaging an image captured on the water before entering the water next time. Save to.

  For example, the imaging apparatus 100 stores an image obtained by imaging a subject on the ground in a directory named “20060214 Ground No. 001”. Thereafter, when the user 190 dives underwater and captures an image of the subject, the imaging apparatus 100 stores the obtained image in a directory named “20060214 underwater No001”. When the user 190 goes up on the water and picks up an image of the subject, the imaging apparatus 100 stores the obtained image in a directory named “20060214 water No. 001”. The imaging apparatus 100 stores the obtained image in a directory named “20060214 underwater No002”.

  Note that the imaging apparatus 100 obtains position information and map information from the outside, thereby determining whether the image is on the ground or on the water, and a directory having a name including a term for identifying whether the image is on the ground or on the water The obtained image is stored. In this way, the imaging apparatus 100 differs between an image obtained by taking an image on the ground and an image obtained by taking an image on the water, such as “20060214 Ground No001”, “2006060214 Water No001”, and the like. It is possible to save it in the directory of the name.

  FIG. 2 shows an example of a block configuration of the imaging apparatus 100. The imaging apparatus 100 includes an underwater sensor unit 110, an instruction input unit 200, an imaging unit 210, an imaging interval measurement unit 220, an identical state period measurement unit 230, a recording destination determination unit 240, a recording unit 250, a state determination unit 260, and a state detection unit. 270, an underwater sensor unit 110, and a position acquisition unit 284. The underwater sensor unit 110 includes a pressure sensor 280 and a conductive sensor 282.

  The imaging unit 210 captures an image. The conductivity sensor 282 detects the degree of conductivity around the imaging device 100. The pressure sensor 280 detects the pressure applied to the imaging device 100.

  The state detection unit 270 detects whether the imaging apparatus 100 is in a state where it is in water or not. Specifically, the state detection unit 270 determines that the imaging device 100 is in water when the degree of conductivity detected by the conductivity sensor 282 is greater than a predetermined degree of conductivity. In addition, the state detection unit 270 determines that the degree of conductivity detected by the conductive sensor 282 is greater than the predetermined degree of conductivity, and the pressure detected by the pressure sensor 280 is greater than the predetermined pressure. You may detect that the imaging device 100 is underwater. Note that the pressure sensor 280 may start the pressure detection operation on condition that the degree of conductivity detected by the conductivity sensor 282 is larger than a predetermined degree of conductivity.

  Based on the detection result of the state detection unit 270, the state determination unit 260 determines that the state of the imaging device 100 is not underwater in a period from when the imaging unit 210 previously captured an image to when it newly captured an image. It is determined whether or not a transition is made between a state in water. Then, when the state determination unit 260 determines that the state of the imaging device 100 has changed, the recording destination determination unit 240 selects a recording destination that is different from the recording destination where the image captured by the imaging unit 210 was recorded last time. 210 is determined as a recording destination of a newly captured image. Then, the recording unit 250 records the image newly captured by the imaging unit 210 in the recording destination determined by the recording destination determination unit 240.

  Specifically, the recording unit 250 records an image captured by the imaging unit 210 in a directory. In this case, when the state determination unit 260 determines that the state of the imaging apparatus 100 has transitioned, the recording destination determination unit 240 sets a directory that is different from the directory in which the image captured by the imaging unit 210 last time is recorded. Is determined as a directory for recording newly captured images. Note that the recording destination determined by the recording destination determination unit 240 is not limited to the directory. For example, the recording destination determination unit 240 may determine a physically different storage medium as the different recording destination. In addition, when the recording unit 250 records an image on the same storage medium, the recording destination determination unit 240 selects one of a plurality of logical areas associated with the plurality of logical areas on the storage medium. A logical area associated with a different logical area may be determined as the different recording destination.

  The imaging interval measurement unit 220 is configured such that the imaging unit 210 performs an image in the same state of the imaging device 100 as the state of the imaging device 100 at the time of the first imaging from the first imaging when the imaging unit 210 captures an image. The imaging interval until the second imaging when the image is newly captured is measured. The recording destination determination unit 240 is a case where the state determination unit 260 determines that the state of the imaging apparatus 100 has transitioned when the imaging interval measured by the imaging interval measurement unit 220 is shorter than a predetermined time width. Also, the same recording destination as the recording destination where the image captured by the imaging unit 210 during the first imaging is recorded is determined as the recording destination of the image newly captured by the imaging unit 210 during the second imaging.

  Specifically, the imaging interval measurement unit 220 captures images in a state where the imaging device 100 is underwater from the first imaging time when the imaging unit 210 captures an image while the imaging device 100 is in water. The imaging interval until the second imaging when the unit 210 newly captures an image is measured. The recording destination determination unit 240 is a case where the state determination unit 260 determines that the state of the imaging apparatus 100 has transitioned when the imaging interval measured by the imaging interval measurement unit 220 is shorter than a predetermined time width. In addition, the same recording destination as the recording destination where the image captured by the imaging apparatus 100 during the first imaging is recorded is determined as the recording destination of the image newly captured by the imaging unit 210 during the second imaging. According to such control, for example, even if the user 190 once rises from underwater to the water, the imaging apparatus 100 is the same as the previous image taken underwater if the imaging interval from when the last image was taken underwater is short. Images newly taken underwater can be stored in the directory. Accordingly, for example, when the user 190 repeats imaging while snorkeling, it is possible to prevent the recording destination directory from being frequently changed.

  In addition, the same state period measurement unit 230 starts the imaging unit in the state of the imaging device 100 that is the same as the state of the imaging device 100 at the time of the first imaging from the first imaging when the imaging unit 210 captures an image. The period during which the state in which the state of the image capturing apparatus 100 is different from the state of the image capturing apparatus 100 at the time of the second image capturing continues until the second image capturing time when the image 210 is newly captured is measured. When the state determination unit 260 determines that the state of the imaging apparatus 100 has transitioned when the length of the period measured by the same state period measurement unit 230 is shorter than a predetermined time width, the recording destination determination unit 240 Even so, the same recording destination as the recording destination where the image captured by the imaging unit 210 during the first imaging is recorded is determined as the recording destination of the image newly captured by the imaging unit 210 during the second imaging.

  Specifically, based on the detection result of the state detection unit 270, the same state period measurement unit 230 starts from the first imaging when the imaging unit 210 captures an image while the imaging device 100 is in water. The period during which the state in which the imaging device 100 is on the water continues until the second imaging time when the imaging unit 210 newly takes an image while the imaging device 100 is in the water is measured. When the state determination unit 260 determines that the state of the imaging apparatus 100 has transitioned when the length of the period measured by the same state period measurement unit 230 is shorter than a predetermined time width, the recording destination determination unit 240 Even so, the same recording destination as the recording destination where the image captured by the imaging device 100 during the first imaging is recorded is determined as the recording destination of the image newly captured by the imaging unit 210 during the second imaging.

  According to such control, for example, even if the user 190 rises from the water to the water once, the imaging device 100 is in the same directory as the image captured in the previous water if the time of being on the water is short. Stores newly captured images taken underwater. Accordingly, for example, when the user 190 repeats imaging while snorkeling, it is possible to prevent the recording destination directory from being frequently changed.

  The position acquisition unit 284 acquires the position of the imaging device 100. For example, the position acquisition unit 284 acquires the position information of the imaging apparatus 100, for example, the latitude and longitude of the imaging apparatus 100, by acquiring GPS information from GPS satellites. The position acquisition unit 284 may receive map information indicating whether or not the position indicated by the position information is on the ground in association with the position information. In addition, the position acquisition unit 284 may receive position information indicating whether or not the imaging apparatus 100 is on the ground. Then, based on the position information of the imaging device 100 acquired by the position acquisition unit 284 and the signal from the underwater sensor unit 110, the state detection unit 270 determines that the imaging device 100 is not in a state of being underwater. You can judge whether you are on the water or on the ground.

  FIG. 3 shows an example of an imaging flow by the imaging apparatus 100. When the power is turned on (S300), the imaging apparatus 100 performs a date check operation (S310). The imaging apparatus 100 initializes date setting and control parameters as necessary in the date confirmation operation in S310. Details of this date confirmation operation will be described with reference to FIG.

  Then, based on the detection result of the underwater sensor unit 110, it is determined whether or not the imaging device 100 is in water (S320). If it is determined in S320 that the imaging device 100 is underwater, the imaging device 100 automatically sets the imaging mode of the imaging device 100 to the underwater mode (S322). In S322, when the imaging mode of the imaging device 100 is set to an imaging mode other than the underwater mode, the imaging device 100 may notify the user 190 of a warning that the underwater mode should be set. Good. If it is determined in S320 that the imaging device 100 is not underwater, the imaging device 100 automatically sets the imaging mode of the imaging device 100 to the auto mode (S324). In S324, when the imaging mode of the imaging device 100 is set to the underwater mode, the imaging device 100 issues a warning to the user 190 that the imaging mode other than the underwater mode should be set (for example, the auto mode). May be notified.

  Then, the imaging apparatus 100 determines whether or not the release button has been pressed by the user 190 (S330). If the release button is pressed, the subject is imaged and recorded (S332), and the process returns to S330. Details of the operation at the time of imaging in S332 will be described with reference to FIG. If the release button has not been pressed, the state determination unit 260 determines whether the state of the imaging device 100 has changed (S340). When the state determination unit 260 determines in S340 that the state of the imaging device 100 has changed, the imaging device 100 returns the process to S320.

  When the state determination unit 260 determines in S340 that the state of the imaging device 100 has not changed, the imaging device 100 determines whether or not the power is turned off (S350). If the power is not turned off, the imaging apparatus 100 returns the process to S330. When the power is turned off, the imaging apparatus 100 ends the process. In the above description, the operation of the image pickup apparatus 100 is described using a sequential operation flow for the purpose of easy understanding. However, in addition to such an operation flow, the image pickup apparatus 100 may include, for example, S340, Interrupt processing may be performed for the determination processing in S340 and S350, or the series of operations during imaging in S332 and the determination processing in S340 may be performed in parallel.

  FIG. 4 shows an example of the processing flow of the imaging operation in S332. The imaging apparatus 100 performs a date check operation (S410). Then, the state determination unit 260 determines whether or not the state has transitioned from the previous imaging of the subject to the present (S420). If the state determination unit 260 determines that the state has changed in S420, the recording destination determination unit 240 determines from the measurement result of the same state period measurement unit 230 that the predetermined time has elapsed since the last imaging in the same state. It is determined whether or not (for example, 20 minutes) has elapsed (S430).

  In S430, when it is determined that a predetermined time (for example, 20 minutes) or more has elapsed since the last imaging in the same state, A non-underwater counter that counts the number of times the water has risen on the same day is incremented (S440). In S440, when the state determination unit 260 determines that the imaging device 100 is underwater, the underwater counter is incremented, and when the state determination unit 260 determines that the imaging device 100 is not underwater. Increments the non-underwater counter. The imaging device 100 manages the non-underwater counter separately as a water counter and a ground counter. When the imaging device 100 is on the ground, the ground counter is incremented. When the imaging device 100 is on the water, the water counter is incremented. May be.

  Then, the recording destination determining unit 240 sets a different directory as a recording destination (S450). At this time, the recording destination determination unit 240 determines the recording destination directory of the newly captured image using the date, the term indicating whether the subject is underwater or on the water, and the underwater counter or the non-underwater counter. Then, the recording unit 250 records the image in the directory determined by the recording destination determining unit 240 (S460).

  When it is determined by the state determination unit 260 that the state has not changed in S420, or when it is determined that a predetermined time or more has elapsed since the last imaging in the same state in S430. In step S460, the recording destination determination unit 240 does not determine a new directory and records a newly captured image in a directory in which an image obtained by the previous recording by the recording unit 250 is recorded. In the example of this figure, whether or not to record in a new directory is determined based on at least the imaging interval by the imaging interval measuring unit 220 in S430. As another form, in S430, the recording destination determining unit 240 is determined. Needless to say, based on the measurement result of the same state period measurement unit 230, it may be determined whether or not the state before the transition immediately before the current state continues for a predetermined time or more.

  FIG. 5 shows an example of a processing flow in the date change operation. The imaging apparatus 100 determines whether or not the date has been changed between the previous imaging time and the current time (S510). The imaging apparatus 100 may acquire the current date and time by using the clock function of the imaging apparatus 100 itself, or by detecting a standard radio wave indicating the standard time when the imaging apparatus 100 is not in water. In S510, when the imaging apparatus 100 determines that the date has been changed between the previous imaging time and the present time, the current date data is set (S520). This date data is used for determining the directory name of the recording destination in S450. Then, both the underwater counter and the non-underwater counter are initialized to 0 (S530). When the imaging apparatus 100 manages the non-underwater counter separately for the water counter and the ground counter, the underwater counter, the water counter, and the ground counter are initialized to 0 in S530.

  FIG. 6 illustrates an example of a recording destination directory that is changed according to the state of the imaging apparatus 100. The state detection unit 270 determines that the imaging device 100 is not underwater from the time t0 to the time t1, and the recording unit 250 determines the image captured during that period by the recording destination determination unit 240. Record in a directory named “20060214 Ground No. 001”. Then, during the period from time t1 to time t2, the state detection unit 270 determines that the imaging device 100 is continuously underwater, and the recording unit 250 records an image captured during that period. The file is recorded in the directory named “20060214 underwater No001” determined by the destination determination unit 240.

  Then, the state detection unit 270 determines that the imaging device 100 is not underwater from the time t2 to the time t3, and the recording unit 250 uses the recording destination determination unit 240 to select an image captured during that period. Record in the determined directory named “20060214 Water No. 001”. Then, during the period from time t3 to time t8, the state detection unit 270 determines that the imaging device 100 is continuously underwater, and the recording unit 250 records an image captured during that period. The file is recorded in the directory named “20060214 underwater No 002” determined by the destination determination unit 240. Then, the state detection unit 270 determines that the imaging device 100 is not underwater from time t8 to time t9, and the recording unit 250 uses the recording destination determination unit 240 to capture images captured during that period. It records in the determined directory named “20060214 Water No. 002”. The recording destination determination unit 240 determines the first eight characters of the directory name (for example, “20060214”) using the date data. Then, the recording destination determining unit 240 determines the next two characters (for example, “underwater”, “terrestrial”, “waterborne”) based on the detection result of the state detection unit 270. The recording destination determination unit 240 determines the last three characters (for example, “001”, “002”, etc.) based on the values of the underwater counter, the water counter, and the ground counter.

  It should be noted that the state detection unit 270 determines that the imaging device 100 is underwater during the period from time t1 to t2 and from time t3 to t8. The recording unit 250 may record the water depth information in association with the image captured by the imaging unit 210 during the period when the state detection unit 270 determines that the imaging device 100 is underwater. The water depth information may be pressure information detected by the pressure sensor 280, or may be water depth associated with the pressure detected by the pressure sensor 280.

  Note that the imaging device 100 is located in substantially the same water depth zone during the time t4 to t5 and the time t6 to t7, but the imaging device 100 is in the water depth zone between the time t5 and the time t6. Images are taken in deep water, which is very different from In such a case, the recording destination determining unit 240 captures an image captured during the period from time t4 to t5 and a period from time t6 to t7, and an image captured during the period from time t5 to time t6. May be recorded in different subdirectories. In this case, the underwater sensor unit 110 detects the water pressure applied to the imaging device 100 detected by the pressure sensor 280. And the state detection part 270 detects the water depth in which the imaging device 100 is located based on the pressure which the underwater sensor part 110 detected. Then, based on the water depth detected by the state detection unit 270, the state determination unit 260 determines whether or not the change amount of the water depth at the position of the imaging device 100 is larger than a predetermined change amount of the water depth. Then, when the state determination unit 260 determines that the change amount of the water depth is larger than the predetermined change amount of the water depth, the recording destination determination unit 240 determines the recording destination where the image already captured by the imaging unit 210 is recorded. A different recording destination is determined as a recording destination of an image that is newly captured by the imaging unit 210.

  FIG. 7 shows an example of a recording destination directory that is changed according to the state of the imaging apparatus 100 and the imaging timing. The imaging interval measurement unit 220 manages the previous imaging time, which is the time when the previous imaging was performed in water, and the imaging unit until the state determination unit 260 determines that the state of the imaging device 100 has transitioned to the water. Each time 210 performs imaging in water, the previous imaging time is updated with the imaging time. When the state determination unit 260 determines that the imaging device 100 has transitioned from underwater to water, the difference between the time when the imaging unit 210 first images in water and the previous imaging time is calculated as the imaging interval. To do. For example, the imaging interval measurement unit 220 calculates 8 minutes that is the difference between the times t2 and t1 as the imaging interval. In the example of this figure, since the calculated imaging interval (8 minutes) is shorter than the predetermined interval (20 minutes), the recording destination determining unit 240 refers to the images obtained at times t1 and t2 as “20060214 underwater No001”. Decide to record in the named directory. Since the imaging interval (22 minutes) calculated by the same method is longer than the predetermined interval (20 minutes) in the period from time t2 to t3, the recording destination determination unit 240 newly creates “20060214 underwater No 002”. To output to a different directory.

  Next, for the period from time t4 to t7, the imaging interval (19 minutes) calculated in the same manner is shorter than the predetermined interval (20 minutes). On the other hand, in the period from time t4 to t7, the same state period measurement unit 230 measures the water period (16 minutes), which is a period (time t5 to t6) continuously present on the water. In such a case, the recording destination determination unit 240 has an image captured at time t7 because the water period (16 minutes) measured by the same state period measurement unit 230 is longer than the predetermined interval (15 minutes) that should be regarded as the same state. Is recorded in a newly created directory “20060214 underwater No003”, which is different from the image captured at time t4. Further, since the period from time t8 to t9 is shorter than any of the predetermined intervals (15 minutes and 20 minutes), the recording destination determination unit 240 uses the same directory “20060214 underwater No003 for images taken in water after time t9. To record.

  As described above, when the user 190 takes an image of the subject while repeatedly going out on the water or diving in the water as in snorkeling, the user 190 frequently takes an image while diving in the water. It is possible to prevent the directory from being updated.

  FIG. 8 shows an exemplary hardware configuration of a computer 1500 related to the imaging apparatus 100. The computer 1500 includes a CPU peripheral unit including a CPU 1505, a RAM 1520, a graphic controller 1575, and a display device 1580 connected to each other by a host controller 1582, and a communication interface 1530 connected to the host controller 1582 by an input / output controller 1584.

The hard disk drive 1540 stores programs and data used by the CPU 1505 in the computer 1500. The communication interface 1530 communicates with the image capturing apparatus 100 via a network, and provides programs and data to the image capturing apparatus 100. The CD-ROM drive 1560 reads a program or data from the CD-ROM 1595 and provides it to the hard disk drive 1540 and the communication interface 1530 via the RAM 1520.

  The input / output controller 1584 is connected to the ROM 1510, the flexible disk drive 1550, and the relatively low-speed input / output device of the input / output chip 1570. The ROM 1510 stores a boot program executed when the computer 1500 is started up, a program depending on the hardware of the computer 1500, and the like. The flexible disk drive 1550 reads a program or data from the flexible disk 1590 and provides it to the hard disk drive 1540 and the communication interface 1530 via the RAM 1520. The input / output chip 1570 connects various input / output devices via a flexible disk drive 1550 and, for example, a parallel port, a serial port, a keyboard port, a mouse port, and the like.

  A program provided to the communication interface 1530 via the RAM 1520 is stored in a recording medium such as the flexible disk 1590, the CD-ROM 1595, or an IC card and provided by the user. The program is read from the recording medium, provided to the communication interface 1530 via the RAM 1520, and transmitted to the imaging apparatus 100 via the network. The program transmitted to the imaging apparatus 100 is installed and executed in the imaging apparatus 100.
