The shooting information includes a display area for visually recognizing the zoom magnification, the number of pixels, a focus method, an exposure correction value, and the like.

The system control circuit 50 controls the overall operation of the digital camera 100, and specifically comprises a microcomputer. The mode dial switch 60, the shutter switch 62, the zoom switch 66, and the operation unit 70 serve as operation means for inputting various operation instructions to the system control circuit 50. Each of these units is configured by a combination of a single member or a plurality of members such as a switch, a dial, and a touch panel. Specifically, the mode dial switch 60 can switch and set each function mode such as power on / off, still image shooting mode, moving image shooting mode, playback mode, rehearsal mode, and reproduction shooting mode.

The acceleration sensor 300 that is a motion detection unit that detects the motion of the imaging apparatus detects the acceleration of the digital camera 100 and transmits the detected acceleration information to the system control circuit 50. The system control circuit 50 calculates movement information (speed, acceleration) of the digital camera 100 based on the acceleration information, and records it in the nonvolatile memory 56 that is a storage unit as necessary. The movement information of the digital camera 100 is used in a reproduction shooting mode described in detail later.

Next, the rehearsal mode and the reproduction shooting mode, which are the features of the present invention, will be described in detail. The digital camera 100 according to the present invention has two operation modes of a rehearsal mode and a reproduction shooting mode in addition to a normal shooting mode. The rehearsal mode is a mode for setting optical parameters such as how to move the digital camera 100 and the lens 10 in advance by a method described later prior to actual shooting. On the other hand, in the reproducible shooting mode, a symbol for guiding how to move the camera 100 set in the rehearsal mode is displayed on the display unit 28, or optical parameters such as the lens 10 set in the rehearsal mode are automatically set by the method described later. Or to reproduce. This is a mode that reproduces the manner of shooting in the rehearsal mode.

3A and 3B are flowcharts illustrating a rehearsal mode routine of the digital camera 100 according to the present embodiment. The operation of the digital camera 100 in the rehearsal mode of this embodiment will be described with reference to FIG. The rehearsal mode process is started by selecting the rehearsal mode with the mode dial 60. First, the digital camera 100 accepts changes in optical parameters such as the optical zoom position, aperture value, and focus position of the lens 10 (step 101). In step 102, it is determined whether or not the initial state of the optical parameters is a state desired by the user. If it is determined that the setting of the initial state of the optical parameters has been completed (Y in step 102), the optical parameters at that time are stored in the nonvolatile memory 56 as the initial state of the photographing lens 10 (step 103). If it is determined that the initial setting of the optical parameters has not been completed (N in Step 102), the process returns to Step 101.

When step 103 ends, in step 104, the digital camera 100 determines whether there is an instruction to start storing movements of the digital camera 100 such as panning and tilting. If it is determined that there is a motion storage start instruction for the digital camera 100 (Y in step 104), the motion of the digital camera 100 is stored in time series in step 105. Subsequently, at step 106, it is determined whether or not there is an instruction to end the movement of the digital camera 100. If it is determined by a predetermined operation on the operation unit 70 by the user that there is an instruction to end the motion memory of the digital camera 100 (Y in step 106), the process proceeds to step 107. If it is determined in step 106 that the user's predetermined operation on the operation unit 70 is not confirmed and there is no instruction to end the motion storage of the digital camera 100 (N in step 106), the process returns to step 105. In step 107, it is determined whether there is an instruction to redo the movement of the digital camera 100. If it is determined by a predetermined operation on the operation unit 70 by the user that there is an instruction to re-store the movement (Y in step 107), the stored movement of the digital camera 100 stored in step 108 is deleted. Then, the process proceeds to Step 105. If it is determined in step 107 that there is no instruction to redo the movement of the digital camera 100 by a predetermined operation on the operation unit 70 by the user (N in step 107), the process proceeds to step 109. In step 109, a motion setting file is created from the motion memory of the digital camera 100 and stored in the nonvolatile memory 56, and the motion memory of the original digital camera 100 is deleted. If it is determined in step 104 that there is no motion memory start instruction of the digital camera 100 by a predetermined operation on the operation unit 70 by the user (N in step 104), the process proceeds to step 110.

In step 110, it is determined whether there is an instruction to start setting optical parameters of the lens 10 of the digital camera 100, the aperture value, and the focus position. If it is determined by a predetermined operation on the operation unit 70 by the user that there is an instruction to start setting optical parameters (Y in step 110), the process proceeds to step 111. If it is determined in step 110 that there is no instruction to start setting optical parameters by a predetermined operation on the operation unit 70 by the user (N in step 110), the process proceeds to step 129. In step 111, it is determined whether or not there is an instruction to start setting the optical zoom position of the lens 10 of the digital camera 100. If it is determined by a predetermined operation on the operation unit 70 by the user that there is an instruction to start setting the optical zoom position (Y in step 111), the process proceeds to step 112. In step 112, the optical zoom position is stored in time series while changing the optical zoom position by the user's operation of the zoom switch 66, and the process proceeds to step 113.

In step 113, it is determined whether there is an instruction to end the storage of the optical zoom position. If it is determined by a predetermined operation on the operation unit 70 by the user that there is an instruction to end storage of the optical zoom position (Y in step 113), the process proceeds to step 114. If the predetermined operation on the operation unit 70 by the user is not confirmed in step 113 and it is determined that there is no instruction to end storing the optical zoom position (N in step 113), the process returns to step 112. In step 114, it is determined whether there is an instruction to re-store the optical zoom position. If it is determined by a predetermined operation on the operation unit 70 by the user that there is an instruction to re-store the optical magnification position (Y in step 114), in step 115, the most recent optical magnification position is determined. The memory is erased, and then the process proceeds to step 112. If it is determined in step 114 that there is no instruction to re-store the optical zoom position by a predetermined operation on the operation unit 70 by the user (N in step 114), the process proceeds to step 116. If it is determined in step 111 that there is no instruction to start setting the optical zoom position by a predetermined operation on the operation unit 70 by the user (N in step 111), the process proceeds to step 116.

In step 116, it is determined whether there is an instruction to start setting the aperture amount of the taking lens 10 by the shutter 12 having the aperture function of the digital camera 100. If it is determined by a predetermined operation by the user on the operation unit 70 that there is an instruction to start setting the aperture amount (Y in step 116), the process proceeds to step 117. In step 117, the state of the optical parameters of the photographing lens is changed so as to be the same as the initial state of the optical parameters of the photographing lens stored in step 103. When step 117 ends, the process proceeds to step 118.

In step 118, if there is stored data of the optical zoom position, the change of the optical zoom position is automatically reproduced along the time series. At the same time, while changing the aperture amount by the user's operation on the operation unit 70, the change in the aperture amount is stored in association with the stored time series of changes in the optical zoom position. When there is no storage data of the optical zoom position, the optical zoom position remains in the initial state of the optical parameters of the photographing lens stored in step 103, and the user operates the operation unit 70. While changing the aperture amount, changes in the aperture amount are stored in time series. When step 118 ends, the process proceeds to step 119. In step 119, it is determined whether there is an instruction to end the storage of the aperture amount. If it is determined by a predetermined operation on the operation unit 70 by the user that there is an instruction to end the aperture amount storage (Y in step 119), the process proceeds to step 120. If it is determined in step 119 that the user's predetermined operation on the operation unit 70 has not been confirmed and there is no instruction to end the storage of the aperture amount (N in step 119), the process returns to step 118.

In step 120, it is determined whether there is an instruction to redo the storage of the aperture amount. If it is determined by a predetermined operation on the operation unit 70 by the user that there is an instruction to re-store the aperture value (Y in step 120), the memory of the most recent aperture value is erased in step 121, and then Proceed to step 118. If it is determined in step 120 that there is no instruction to redo the storage of the aperture amount by a predetermined operation on the operation unit 70 by the user (N in step 120), the process proceeds to step 122. When it is determined in step 116 that there is no instruction to start setting the aperture amount by a predetermined operation on the operation unit 70 by the user (N in step 116), the process proceeds to step 122.

In step 122, it is determined whether or not there is an instruction to start setting the focus distance of the taking lens 10 of the digital camera 100. If it is determined by a predetermined operation on the operation unit 70 by the user that there is an instruction to start setting the focus distance (Y in step 122), the process proceeds to step 123. In step 123, the state of the optical parameters of the photographing lens is changed so as to be the same as the initial state of the optical parameters of the photographing lens stored in step 103. When step 123 ends, the process proceeds to step 124. In step 124, if both the optical zoom position storage data and the aperture amount storage data exist, the optical zoom position and aperture change are automatically reproduced in time series. At the same time, the change in the focus position while changing the focus distance by the user's operation on the operation unit 70 is associated with the stored time series of the change in the optical zoom position and the change in the aperture amount. Remember. In addition, if there is either storage data for the optical scaling position or storage data for the aperture amount, the change in which the storage data for the optical scaling position or aperture amount is stored is automatically performed along the time series. And at the same time reproduce: That is, while changing the focus distance by the user's operation on the operation unit 70, the change in the focus position is expressed as a time series of changes in which the stored optical scaling position and the stored amount of the diaphragm amount are present. Store it in association. If there is no storage data for the optical zoom position and storage data for the aperture amount, the optical zoom position and the aperture amount are left in the initial state of the optical parameters of the photographing lens stored in step 103. And the focus position is memorize | stored along a time series, changing a focus distance by operation to the operation part 70 of a user. That is, the lens optical system is automatically driven according to the contents of the optical parameters that have already been set, and the next change in the optical parameters is stored. When step 124 ends, the process proceeds to step 125.

In step 125, it is determined whether there is an instruction to end the storage of the focus distance. If it is determined by a predetermined operation on the operation unit 70 by the user that there is an instruction to end the storage of the focus distance (Y in step 125), the process proceeds to step 126. If the predetermined operation on the operation unit 70 by the user is not confirmed in step 125 and it is determined that there is no instruction to end the storage of the focus distance (N in step 125), the process returns to step 124. In S126, it is determined whether there is an instruction to redo the storage of the focus distance. When it is determined that the instruction for re-recording the focus distance is given by a predetermined operation on the operation unit 70 by the user (Y in step 126), the memory of the latest focus distance is erased in step 127, and then Proceed to step 124. If it is determined in step 126 that there is no instruction to redo the storage of the focus distance by a predetermined operation on the operation unit 70 by the user (N in step 126), the process proceeds to step 128. If it is determined in step 122 that there is no instruction to start setting the focus distance by a predetermined operation on the operation unit 70 by the user (N in step 122), the process proceeds to step 128.

In step 128, if any of the optical zoom position, aperture value, and focus position of the lens 10 is stored, the following is performed. That is, an optical parameter setting file for reproducing them simultaneously in the reproduction photographing mode is created based on the storage of the optical zoom position, aperture value, and focus position, and then stored in the nonvolatile memory 56. Thereafter, the memory of the optical zoom position, aperture value, and focus position is erased. When step 128 ends, the process proceeds to step 129. In step 129, it is determined whether there is an instruction to end the rehearsal mode. If it is determined by a predetermined operation on the operation unit 70 by the user that there is an instruction to end the rehearsal mode (Y in step 129), the process proceeds to step 130. When it is determined in step 129 that there is no instruction to end the rehearsal mode by a predetermined operation on the operation unit 70 by the user (N in step 129), the process proceeds to step 103.

In step 130, the created motion setting file and the optical parameter setting file are combined in the order of creation to create a rehearsal file. This rehearsal file is used to reproduce the rehearsal in the reproduction shooting mode described later. When step 130 ends, the rehearsal mode process ends.

The order of setting the optical parameters in the rehearsal mode is the order of the optical zoom position, the aperture value, and the focus position for the following reason. That is. This is because the aperture F value of the lens 10 is changed by changing the optical zoom position, so that it is more convenient to set the aperture value after setting the optical zoom position. In addition, when the aperture value is changed, the depth of field of the lens 10 changes, so it is more convenient to set the focus position after setting the aperture value.

Next, the operation in the reproduction shooting mode will be described. By applying a predetermined operation to the mode dial 60, the reproduction shooting mode process is started. In the reproduction shooting mode, the user can select a rehearsal file to be reproduced by performing a predetermined operation on the operation unit 70. After the rehearsal file to be reproduced is selected by the user, when an instruction to start rehearsal reproduction is started by a predetermined operation on the operation unit 70 of the user, the video camera is started and the digital camera 100 is started at the same time. Starts the action to reproduce the rehearsal.

In this embodiment, as an example of rehearsal reproduction, a rehearsal in which the optical parameter is changed after panning in the right direction and tilted upward will be reproduced at the time of actual shooting. FIG. 1 is a diagram illustrating display contents of the image display unit 28 of the digital camera 100 in the reproduction shooting mode. When an instruction to start rehearsal reproduction is issued in the reproduction shooting mode, the image display unit 28 of the digital camera 100 has display contents as shown in FIG. Reference numeral 301 denotes a symbol for guiding the direction in which the user moves the digital camera 100. In this embodiment, the symbol is used to instruct to pan rightward. The user can reproduce the movement of the digital camera 100 during the rehearsal by panning the digital camera 100 in the right direction according to this symbol. The gauge 302 and the bar 303 are symbols indicating the speed at which the user moves the digital camera 100. The speed at which the gauge 302 and the bar 303 are moved is indicated by the position of the gauge 302 on the bar 303. The movement of the digital camera 100 is detected by the acceleration sensor 300, and the bar 303 moves along the gauge 302 according to the difference between the detected content and the rehearsal.

Specifically, if the bar 303 is at an appropriate position in the gauge 302, it indicates that the speed at which the user moves the digital camera 100 is the same as that during rehearsal. In addition, when the bar 303 is on the left side of the gauge 302 from the appropriate position, it indicates that the speed at which the user moves the digital camera 100 is slower than during rehearsal. When the bar 303 is on the right side of the gauge 302 in the right side, it indicates that the user moves the digital camera 100 faster than during rehearsal. The larger the amount of deviation of the bar 303 from the appropriate position in the gauge 302, the greater the deviation of the moving speed of the digital camera 100 from the rehearsal. Therefore, when the user moves the digital camera 100 so that the bar 303 is at an appropriate position in the gauge 302, the speed of the movement of the digital camera 100 during rehearsal (in this example, panning in the right direction) is also reproduced. be able to. In the example shown in FIG. 1A, it is indicated that the speed at which the user moves the digital camera 100 is slower than that during rehearsal. In this case, the digital camera 100 may be moved faster. An area 304 is a symbol indicating the amount of movement that the user moves the digital camera 100. According to the movement of the digital camera 100 detected by the acceleration sensor 300, the band 305 extends to the right from the left end in the area 304, and it is necessary to move until the band 305 reaches the right end of the area 304. Therefore, the user can know the remaining amount of movement of the digital camera 100 by looking at the area 304 and the band 305.

Reference numeral 306 denotes a display for notifying the next operation after the end of the current operation. The symbol for the notice is changed to a white symbol so that it can be easily distinguished from the symbol indicating the current operation. In this example, the circle is a symbol indicating that the optical parameter is automatically changed. Accordingly, in FIG. 1A, after the digital camera 100 is panned to the right until the band 305 reaches the right end of the region 304, it is forewarned that the optical parameters are automatically changed.

FIG. 1B shows the display contents of the image display unit 28 of the digital camera 100 after panning the digital camera 100 to the right by a predetermined amount. In the present embodiment, after the digital camera 100 is panned to the right by a predetermined amount, the optical zoom position, aperture value, and focus position, which are optical parameters, are automatically changed simultaneously as set in the rehearsal mode. . Reference numeral 307 denotes a symbol indicating that the optical parameter is currently automatically changed. An area 308 is a symbol indicating the time required to complete the change of the optical parameters of the digital camera 100. As the optical parameter change proceeds, the band 309 extends upward from the lower end in the region 308, and the optical parameter change is automatically performed until the band 309 reaches the upper end of the region 308. Therefore, the user can know how much time remains for changing the optical parameters. Reference numeral 310 denotes a display for notifying the next operation after the end of the current operation. In this example, the digital camera 100 is tilted upward after the band 309 reaches the upper end of the region 308 and the change of the optical parameters is completed.

FIG. 1C shows the display content of the image display unit 28 of the digital camera 100 after a predetermined time has elapsed and the change of the optical parameters is completed. After the change of the optical parameters is completed, the digital camera 100 is tilted upward to reproduce the rehearsal mode. Reference numeral 311 denotes a symbol indicating the direction in which the digital camera 100 is moved. In this embodiment, 311 is a symbol for instructing to tilt upward. By tilting the digital camera 100 upward in accordance with this symbol, the movement of the digital camera 100 during rehearsal can be reproduced. As described in FIG. 1C, the upward movement speed is indicated by the gauge 302 and the bar 303, and the upward movement amount is indicated by the region 304 and the band 305. Reference numeral 312 denotes a symbol for notifying that the rehearsal reproduction is finished when the upward tilt is finished by a predetermined amount. When the digital camera 100 is tilted upward by a predetermined amount, shooting of the moving image is terminated, and the shot moving image is recorded on the recording medium 200.

In the present embodiment, in order to reproduce the setting contents in the rehearsal mode, the display unit 28 is instructed how to move the digital camera 100 and the optical parameters are automatically changed as described above in the reproduction shooting mode. Or This makes it possible to easily reproduce the shooting method during rehearsal during actual shooting.

(Example 2)
In the first embodiment, in the reproduction shooting mode, the optical parameters are automatically set simultaneously with the movement of the digital camera 100, for example, the zoom is automatically performed with the lens 10 simultaneously with the panning of the digital camera 100. The operation is not changed. On the other hand, the second embodiment is characterized in that in the reproduction shooting mode, the digital camera 100 is moved and the optical parameter is automatically changed at the same time.

Hereinafter, the rehearsal mode and the reproduction shooting mode in the second embodiment will be described in detail. FIG. 4 is a flowchart illustrating a rehearsal mode routine of the digital camera 100 according to the present embodiment. The operation of the digital camera 100 in the rehearsal mode of this embodiment will be described with reference to FIG. The rehearsal mode process is started by selecting the rehearsal mode with the mode dial 60.

First, the digital camera 100 accepts changes in optical parameters such as the optical zoom position, aperture value, and focus position of the lens 10 (step 201). In step 202, it is determined whether or not the initial state of the optical parameters is the state desired by the user. If it is determined that the initial setting of the optical parameters has been completed (Y in step 202), the process proceeds to step 203. If it is determined that the initial setting of the optical parameters has not been completed (N in Step 202), the process returns to Step 201.

In step 203, the movement of the digital camera 100 is stored in time series, and the optical magnification position is changed by the user's operation of the zoom switch 66 while the optical magnification position is changed. Store in association with memory. Subsequently, in step 204, it is determined whether or not there is an instruction to end the storage of the movement of the digital camera 100 and the optical zoom position.

The symbol for the notice is changed to a white symbol so that it can be easily distinguished from the symbol indicating the current operation. In this example, the square is a symbol indicating that the holding state is maintained. Accordingly, FIG. 5A shows that after the digital camera 100 is panned to the right until the band 405 reaches the right end of the region 404, the user holds the digital camera 100 without moving it.

FIG. 5B shows display contents of the image display unit 28 of the digital camera 100 after panning the digital camera 100 to the right by a predetermined amount. In this embodiment, after panning the digital camera 100 to the right by a predetermined amount, the user holds the digital camera 100 without moving it. Reference numeral 408 denotes a symbol indicating holding without moving. An area 409 is a symbol indicating the time required to complete the holding of the digital camera 100. As time passes, the band 410 extends rightward from the left end in the area 409 until the band 410 reaches the right end of the area 409. It is necessary to continue holding. Therefore, the user can know how much time remains in the holding state. A rectangle 411 is a symbol indicating that optical scaling is automatically performed, and in this example, indicates that optical scaling is performed in the wide direction. When the band 410 extends rightward from the left end in the region 409 and reaches the same position as the left side of the rectangle 411 in the left-right direction in the drawing, optical scaling is automatically performed. When the right side is reached, the optical scaling is terminated.

In the example of FIG. 5B, since the right end in the region 409 and the right side of the rectangle 411 coincide with each other, it indicates that optical scaling in the wide direction continues until the holding state ends. The state of FIG. 5B is a state in which optical scaling in the wide direction is automatically performed while the user holds the digital camera 100 without moving it. Reference numeral 412 denotes a display for notifying the next operation after the end of the current operation. In this example, the digital camera 100 is tilted upward after the band 410 reaches the right end of the region 409 and the holding state ends.

FIG. 5C shows the display contents of the image display unit 28 of the digital camera 100 after a predetermined time has elapsed and the holding state of the digital camera 100 is finished. After the holding state is completed, the digital camera 100 is tilted upward to reproduce the rehearsal mode. Reference numeral 413 denotes a symbol indicating the direction in which the digital camera 100 is moved. In this embodiment, the symbol 413 is a symbol for instructing to tilt upward. By tilting the digital camera 100 upward in accordance with this symbol, the movement of the digital camera 100 during rehearsal can be reproduced. As described with reference to FIG. 5A, the upward movement speed is indicated by the gauge 402 and the bar 403, and the upward movement amount is indicated by the region 404 and the band 405. A rectangle 414 and a rectangle 415 are symbols indicating that optical scaling is automatically performed. The optical scaling is performed in the same manner as in FIG. 5A. When the band 405 extends to the right and reaches the same position as the left side of the rectangle 414 in the horizontal direction in the figure, the optical scaling is automatically performed. After that, when the band 405 reaches the right side of the rectangle 414, it indicates that the optical scaling is finished. The same applies to the rectangle 415.

The state shown in FIG. 5C is a state after optical scaling in the wide direction is automatically performed while the user tilts the digital camera 100 upward. Currently, optical scaling is performed. Is not done. Thereafter, when the digital camera 100 is tilted upward by a predetermined amount, automatic optical scaling in the tele direction is started. Reference numeral 416 denotes a symbol for notifying that the rehearsal reproduction is finished when the upward tilt is completed by a predetermined amount. When the digital camera 100 is tilted upward by a predetermined amount, shooting of the moving image is terminated, and the shot moving image is recorded on the recording medium 200.
