(First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram illustrating a configuration example of an imaging apparatus according to the present embodiment. Hereinafter, a video camera 100 that records or reproduces a captured moving image on a memory card will be described as an example of the imaging apparatus according to the present embodiment.
In FIG. 1, a microcomputer 101 is connected to a nonvolatile memory 104, a camera signal processing unit 112, a CODEC 141, and a recording control unit 143 via an internal bus 103. The built-in CPU of the microcomputer 101 operates based on the control program stored in the nonvolatile memory 104, and controls each block using the built-in RAM of the microcomputer 101 as a temporary data storage location during operation. When the microcomputer 101 controls each unit, photographing control, recording control, communication control, display control, and the like are realized.

  An operation unit 102 connected to the microcomputer 101 includes a power on / off button, a mode dial for switching between a photographing operation and a reproduction operation, a recording image recording start / stop button, and the like. Tell the microcomputer 101. Note that the power on / off button does not actually turn on / off the power, but functions as a switch for switching the standby state off / on, which requires the minimum power consumption. The GPS 105 connected to the microcomputer 101 functions as an example of position information acquisition means, and measures and notifies the latitude and longitude of the current position of the video camera 100 main body and the current time in response to a request from the microcomputer 101. The GPS 105 may be built in the video camera 100 or a unit that can be attached to and detached from the video camera 100. That is, the video camera 100 only needs to have a means for communicating with the GPS 105 and acquiring the current position. The timer 106 connected to the microcomputer 101 causes the microcomputer 101 to generate an interrupt process when a specified time has elapsed according to the setting of the microcomputer 101. That is, the GPS 105 regularly acquires position information.

  The imaging sensor 111 forms an image of light from a subject that has passed through a lens unit (not shown) on the imaging surface, converts an optical image on the imaging surface into an electrical signal, and outputs the image signal to the camera signal processing unit 112. The camera signal processing unit 112 performs image processing such as color conversion, gamma correction, white balance adjustment, resizing, and the like on the image signal output from the image sensor 111 using parameters based on instructions from the microcomputer 101. The later image signal is output. Based on an instruction from the microcomputer 101, the transition image generation unit 122 accesses the map database 121 stored in a flash memory or the like to acquire map information (map image), and generates transition image data indicating the transition of the position of the main body. Then, an image signal is output to the first switch 131. The generation of the transition image data will be described in detail later. The map database 121 may be built in the video camera 100, or may be an external hard disk that is detachable from the video camera 100, for example. Further, the video camera 100 may be provided with a means for communicating with an external device so as to access the map database 121 in the external device.

  The first switch 131 outputs an image signal output from the camera signal processing unit 112 to the CODEC 141 when recording captured image data based on an instruction from the microcomputer 101. When an image signal is output from the transition image generation unit 122, the image signal is output to the CODEC 141. The second switch 132 outputs an image signal output from the camera signal processing unit 112 to an LCD (Liquid Crystal Display) 151 when performing a shooting operation based on an instruction from the microcomputer 101. Further, when performing a reproduction operation, the image signal output from the CODEC 141 is output to the LCD 151.

  The CODEC 141 encodes the image signal output from the first switch 131 and stores the code data in the buffer memory 142 when recording captured image data or generating transition image data based on an instruction from the microcomputer 101 ( Hold. Further, when performing a reproduction operation, the encoded data stored in the buffer memory 142 is decoded and an image signal is output to the second switch 132. When recording the captured image data or the transition image data based on an instruction from the microcomputer 101, the recording control unit 143 stores the code data temporarily stored in the buffer memory 142 in a predetermined file format as a memory card 144 that is a recording medium. To record. Further, when performing a reproduction operation, the code data recorded on the memory card 144 is read and stored in the buffer memory 142. Note that the imaging apparatus may be controlled by a single piece of hardware, or the entire apparatus may be controlled by a plurality of pieces of hardware sharing the processing.

Next, state transition of the microcomputer 101 will be described with reference to FIG.
FIG. 2 is a diagram illustrating an example of state transition of the microcomputer 101 in the present embodiment.
When the microcomputer 101 is energized to the main body of the video camera 100, the microcomputer 101 enters a standby state 203, which is the minimum necessary power consumption as an initial state. In the normal state 201 including the standby state 203, the microcomputer 101 makes a transition to the timer interrupt state 202 every predetermined time by the timer 106, acquires and records the current position information according to the flowchart of FIG. Return to the state.

  In the standby state 203, when the user turns on the power on / off button of the operation unit 102, the state transitions to the activation state 204. In the activated state 204, transition image data is generated according to the flowchart of FIG. Alternatively, transition is made to either the shooting state 205 or the playback state 206 depending on the state of the mode dial without generating transition image data.

  In the shooting state 205, the recording start / stop button of the operation unit 102 is pressed by the user according to the flowchart of FIG. Here, when the mode dial is changed to the reproduction operation, the shooting state 205 is exited and the state is changed to the reproduction state 206. Also, when the power on / off button of the operation unit 102 is pressed to enter the off state, the shooting state 205 is exited and the standby state 203 is entered. On the other hand, in the reproduction state 206, the image data recorded on the memory card 144 is reproduced in accordance with a user operation. Here, when the mode dial is changed to the shooting operation, the playback state 206 is exited and the shooting state 205 is entered. Further, when the power on / off button of the operation unit 102 is pressed to enter the off state, the playback state 206 is exited and the standby state 203 is entered.

Next, the update processing of the body position history performed by the microcomputer 101 in the timer interrupt state 202 will be described with reference to the flowchart of FIG.
FIG. 3 is a flowchart illustrating an example of a processing procedure for acquiring information on the main body position in the present embodiment.
First, when processing is started in step S301 of FIG. 3, in step S302, the GPS 105 measures the current date and time, and the latitude and longitude at the position of the video camera 100 main body under the control of the microcomputer 101. Then, the microcomputer 101 acquires information on the measurement result.

  Subsequently, in step S303, the microcomputer 101 updates the position history table stored in the nonvolatile memory 104 with the measurement result. FIG. 4 is a diagram illustrating a recording example of the position history table, in which the date and time when the position of the main body of the video camera 100 is acquired, the latitude and longitude, and information indicating whether it is a base point are recorded as a history. . Here, the base point is the position of the main body of the video camera 100 when the transition image data previously recorded on the memory card 144 is generated. However, even when the transition image data is not generated, when the position of the main body of the video camera 100 coincides with a position registered in advance by a user operation such as at home, the position is used as a base point. For example, even if shooting is not performed at home between shooting at the first travel destination and shooting at the second travel destination, the base point of the second trip is the home.

  In the example illustrated in FIG. 4, the row described as <house> indicates that the position of the video camera 100 main body is the user's home. On the other hand, a row described as <α> indicates that transition image data from <home> (user's home) to position α is generated when the user activates the video camera 100 at a travel destination, and the transition image data. Is recorded on the memory card 144.

  Returning to the description of FIG. 3, in step S <b> 304, the microcomputer 101 sets a timer for the next timer interrupt, and the process is terminated. Here, in this embodiment, the longer the elapsed time from when the main body position is detected at the base point, the longer the timer interrupt interval is set, and the longer the history interval recorded in the nonvolatile memory 104 is. For example, if the elapsed time is 0 to 2 hours, record every 1 minute, 2 to 6 hours every 3 minutes, 6 to 24 hours every 12 minutes, and 24 hours or more every 1 hour. Update. This is because the transition image in the present embodiment is a moving image that is fixed for 3 seconds, and when the movement time is long, the history of relatively fine time intervals is not necessary. Therefore, the power consumption and the number of writes to the nonvolatile memory 104 This is because the amount of use of the nonvolatile memory 104 is suppressed.

  When there is no space in the position history table, based on the current update interval, elements acquired at shorter intervals are thinned out and reused. If there is no vacancy even when all the elements are at the longest one-hour interval, the entire process of movement is recorded as a history by thinning out in order from the part with the smaller movement amount.

Next, transition image generation processing performed when the microcomputer 101 is in the activated state 204 will be described with reference to the flowchart of FIG. This process is periodically executed when the microcomputer 101 is in the activated state 204, for example.
FIG. 5 is a flowchart illustrating an example of a processing procedure for generating transition image data.
First, when processing is started in step S501 of FIG. 5, the last base point is referred to from the position history table recorded in the nonvolatile memory 104 by the microcomputer 101 in step S502. Subsequently, in step S503, the microcomputer 101 compares the current position, which is the position when generating the transition image data, with the referenced base point, and determines whether or not it has moved by a predetermined distance (for example, 1 km).

  If the result of this determination is that the distance is equal to or greater than the predetermined distance, in step S504, the transition of the body position from the base point to the current location is detected by the transition image generation unit 122 using the history recorded in the position history table. The transition image data shown is generated. Then, the generated transition image data is encoded by the CODEC 141, stored in the buffer memory 142, which is an example of a holding unit, and the recordable state is ended. On the other hand, if the result of determination in step S503 is that the distance is less than the predetermined distance, the process ends without generating transition image data.

  FIG. 6 is a diagram illustrating an example of a transition image generated by the transition image generation unit 122 when moving from the user's home to the position α illustrated in FIG. 4. In this embodiment, the transition image is a moving image that is fixed for 3 seconds. In the first frame shown in FIG. 6A, a mark 610 indicating the user's home is displayed at the center of the map image 601. A clock display 630 is also displayed, and FIG. 6A shows the time immediately before leaving the user's home.

  6B, the map image 601 scrolls around the main body position 611, and the history of the main body position from the mark 610 to the main body position 611 is represented as a locus 620. The clock display 630 shows the time at the time of the main body position 611. Note that in the process of displaying the map image 601 shown in FIGS. 6A to 6C, the motion of drawing the locus 620 is displayed as a moving image. That is, the state where the locus 620 extends from the mark 610 to the main body position 611 is displayed as a moving image. Similarly, in the clock display 630, the clock hand moves as a moving image, and the passage of time from the mark 610 to the main body position 611 is displayed as a moving image.

  In the last frame shown in FIG. 6C, a mark 612 indicating the position α is displayed at the center of the map image 601, and a history of the main body position 611 from the user's home to the position α is represented by a locus 620. In addition, the clock display 630 indicates the time when the transition image data at the position α is generated.

Next, processing contents in the shooting state 205 of the microcomputer 101 will be described with reference to the flowchart shown in FIG. FIG. 7 is a flowchart illustrating an example of a shooting processing procedure by the video camera 100 according to the present embodiment.
First, when processing is started in step S701 in FIG. 7, in step S702, the imaging sensor 111 and the camera signal processing unit 112 are activated under the control of the microcomputer 101 to start capturing a moving image. Note that the initial state of the microcomputer 101 in the shooting state 205 is a recording stop state 207.

  In step S703, the microcomputer 101 checks the state of the mode dial of the operation unit 102, and determines whether the mode dial is a photographing operation. If the result of this determination is that the mode dial is a shooting operation, processing proceeds to step S704. On the other hand, as a result of the determination in step S703, in other cases, that is, in the case where the mode dial is a reproduction operation, the process proceeds to step S711, and the imaging sensor 111 and the camera signal processing unit 112 are stopped under the control of the microcomputer 101. Exit. After the end, the microcomputer 101 transitions to the reproduction state 206 or the standby state 203.

  On the other hand, in step S704, the state of the recording start / stop button of the operation unit 102 is confirmed to determine whether the recording start / stop button has been pressed. If the result of this determination is that the recording start / stop button has not been pressed, processing returns to step S703. On the other hand, as a result of the determination in step S704, if the recording start / stop button is pressed, it is determined in step S705 whether or not transition image data that can be recorded by the recording control unit 143 is stored in the buffer memory 142. . This is a process for determining whether or not there is transition image data generated in step S504 of FIG. 5 and stored in the buffer memory 142. If transition image data is stored as a result of this determination, the transition image data is recorded on the memory card 144 by the recording control unit 143 in step S706. Further, the microcomputer 101 updates the base point for the position history table of the nonvolatile memory 104. On the other hand, if the result of determination in step S705 is that transition image data is not stored, the process proceeds to step S707.

  Next, in step S707, the microcomputer 101 transitions to the recording state 208 and starts recording captured image data. Specifically, the image signal output from the camera signal processing unit 112 is encoded by the CODEC 141, stored once in the buffer memory 142, and recorded as photographed image data in the memory card 144 by the recording control unit 143. Thereafter, the recording of the photographed image data is continued until the recording of the photographed image data is stopped in step S710.

  Next, in step S708, the microcomputer 101 confirms the state of the mode dial and determines whether or not the mode dial is a photographing operation. If the result of this determination is that the mode dial is an imaging operation, processing proceeds to step S709. On the other hand, as a result of the determination in step S703, in other cases, that is, when the mode dial is in a reproducing operation, the process proceeds to step S710. In step S709, the state of the recording start / stop button is checked to determine whether the recording start / stop button has been pressed. If the result of this determination is that the recording start / stop button has not been pressed, processing returns to step S708.

  On the other hand, if the result of determination in step S709 is that the recording start / stop button has been pressed, or if the result of determination in step S708 is that the mode dial is a playback operation, the process proceeds to step S710. In step S710, the microcomputer 101 transitions to the recording stop state 207, stops recording the captured image data, and returns to step S703.

FIG. 8 is a schematic diagram illustrating a recording example of transition image data and captured image data.
In the example shown in FIG. 8, after moving from the user's home (home) to the position α, the user further moves to the position β and the position γ, and after shooting at each location, returns to the home. Further, the user moves from the home to the position δ and performs shooting. In this case, transition image data and captured image data are recorded in the memory card 144.

  First, the transition image data 801 and the captured image data 802 are recorded by the first shooting after moving from the house to the position α, and subsequently, the different captured image data 803 is recorded at the position α. Next, it moves from position α to position β, and similarly, transition image data 804 and captured image data 805, 806, and 807 are recorded. Furthermore, it moves from the position β to the position γ, and similarly, transition image data 808 and captured image data 809 and 810 are recorded. Thereafter, by returning to the pre-registered home, the base point becomes the home, and the transition image data 811 and the captured image data 812 are recorded by moving from the home to the position δ and performing shooting.

  As described above, according to the present embodiment, the transition to the timer interrupt state 202 is performed, the current position information is acquired at predetermined time intervals, the transition image data is generated in the normal state 201, and the captured image data is recorded. At the time, transition image data was recorded. Thereby, when the recorded transition image data and captured image data are reproduced by the video camera 100 or another device, it is possible to intuitively grasp the transition of the shooting location.

  In this embodiment, an example in which a transition image is a moving image has been described. However, a still image in which a locus is drawn on a map including a movement source and a movement destination may be used. Similarly, even when the transition image is a moving image, the locus may be drawn on the map including the movement source and the movement destination without scrolling around the main body position. In the present embodiment, the locus reflecting the position of the imaging apparatus main body on the way to the destination is drawn, but the transition of the main body position may be expressed by simply connecting the source and destination. . In this embodiment, the transition image is recorded so as to be reproduced before the captured image. However, the transition image may be displayed in the captured image in picture-in-picture.

(Second Embodiment)
Next, an imaging apparatus according to the second embodiment will be described. The video camera according to the present embodiment has substantially the same configuration as the video camera 100 according to the first embodiment shown in FIG. Therefore, description of the block diagram is omitted. The difference is that the microcomputer 101 transitions from the activation state 204 to the shooting state 205 or the reproduction state 206 in parallel with the generation of the transition image data. Specifically, in the state where the microcomputer 101 is transitioning to the activation state 204, the process of generating the transition image data is not performed by the main task, but the process of generating the transition image data shown in FIG. Generate the subtask to be performed. In parallel with the subtask, the mode is switched to either the shooting state 205 or the reproduction state 206 depending on the state of the mode dial.

  In addition, the transition image generation unit 122 of the present embodiment, based on an instruction from the microcomputer 101, first reduces the time for generating transition image data by thinning out the number of frames, resolution, and the like. S is generated. Then, it is possible to selectively generate two types of transition image data H with high quality image quality without thinning out the number of frames and resolution, and the transition image data S described above.

FIG. 9 is a timing chart showing an example of main task and subtask processing when the microcomputer 101 transitions from the activation state 204 to the shooting state 205.
As shown in FIG. 9, in the subtask generated by the microcomputer 101 in the activated state 204, first, the transition image data S is generated by the transition image generation unit 122 and stored in the buffer memory 142 in step S911. Thereafter, in step S912, transition image data H is generated and stored in the buffer memory 142, and the previously stored transition image data S is deleted from the buffer memory 142.

  Further, the microcomputer 101 transitions to the shooting state 205, and activates the image sensor 111 and the camera signal processing unit 112 in step S701 shown in the flowchart of FIG. 7 in the main task. Here, in the stage where the process of step S705 shown in the flowchart of FIG. 7 in the main task is performed, if the step S911 of the subtask is not completed, the transition image data is not stored in the buffer memory 142. Therefore, in this case, the transition image data is not recorded, and the process proceeds to step S707 to start recording the photographed image data. At this time, steps S911 to S912 of the subtask are interrupted.

  On the other hand, in the stage where the process of step S705 is performed, when step S911 of the subtask is completed and step S912 is not completed, the transition image data S stored in the buffer memory 142 is recorded in step S706. To do. At this time, step S912 of the subtask is interrupted. If the subtask step S912 is completed at the stage of performing the process of step S705, the transition image data H stored in the buffer memory 142 is recorded in step S706.

  As described above, according to the present embodiment, the shooting operation can be started before the generation of the transition image data is completed. In addition, when there is a time until the shooting operation is started after activation, transition image data can be generated and recorded according to the time.

(Third embodiment)
Next, an imaging apparatus according to a third embodiment will be described. The video camera according to the present embodiment has substantially the same configuration as the video camera 100 of the first embodiment shown in FIG. Therefore, description of the block diagram is omitted. The difference from the first and second embodiments is that the transition image data is generated and recorded after the photographed image data is recorded. Specifically, the transition image data generation process is not performed in a state where the microcomputer 101 has transitioned to the activation state 204. In the main task, the transition image data recording process in step S706 of the flowchart in the shooting state 205 shown in FIG. 7 is not performed. Instead, during the recording stop process in step S710, a subtask is generated and the transition image data generation process shown in FIG. 5 is performed, and the transition image data is recorded by the subtask.

FIG. 10 is a timing chart illustrating an example of main task and subtask processing when the microcomputer 101 starts recording of captured image data and stops recording in the imaging state 205.
As shown in FIG. 10, first, in the main task, in the recording stop state 207 of the microcomputer 101, an instruction to start recording is waited in step S704 of the flowchart shown in FIG. Upon receiving an instruction to start recording, recording of the captured image data is started through step S707, the microcomputer 101 enters the recording state 208, and waits for an instruction to stop recording in step S708 or S709. When an instruction to stop recording is received, the recording of the captured image data is stopped through step S710, the microcomputer 101 enters the recording stop state 207, and again waits for an instruction to start recording in step S704.

  On the other hand, a subtask is generated in step S710, and the transition image data generation process shown in FIG. 5 is performed in step S1001 in the subtask. In step S1002, the transition image data recording process in step S706 of FIG. 7 performed by the main task in the first and second embodiments is performed.

  Here, before the process of step S1001 of the subtask is completed, when the start of recording of the next photographed image data is instructed and the recording state 208 is changed, the process of step S1001 of the subtask is interrupted. In that case, after the recording stop is instructed again and the transition to the recording stop state 207 is made, the subtask is generated again, and the transition image data is generated and recorded. In addition, before the processing of step S1002 of the subtask is completed, when the start of recording of the next photographed image data is instructed and the recording state 208 is changed, the transition image data is already stored in the buffer memory 142. Therefore, the transition image data stored in the buffer memory 142 can be recorded on the memory card 144 before the next photographed image data is recorded.

  In the case of this embodiment, for example, transition image data when moving from a house (home) to a position α is recorded after the captured image data generated at the position α. On the other hand, since it is desirable that the transition image data is reproduced before the photographed image data during reproduction, the date and time immediately before recording the photographed image data is used as additional information of the image data or a time stamp of the file. For example, when creating and recording the transition image data when moving from the house to the position α, refer to the shooting time information of the captured image data instead of the date and time when the transition image data was actually recorded, and at the position α. The time immediately before the first recorded image data is recorded is used.

  As described above, according to the present embodiment, the transition image data is generated after the captured image data is recorded, so that the process of generating the transition image data can be minimized.

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.
