For example, there is a photography preference that “the polarizing filter is exclusively used for still image photography and not used at all for moving image photography”. On the other hand, even when using a polarizing filter when shooting a movie, “I want to take a movie while rotating the polarizing filter to properly capture changes in the polarization effect”, “Polarized component that oscillates the rotation angle of the polarizing filter horizontally. I want to shoot a movie as if I was wearing polarized sunglasses by fixing it at a rotation angle that cuts the '' and `` Polarized when using and not using the polarizing filter by driving the polarizing filter inserted and removed There are various shooting preferences such as “I want to compare the effects”.

  However, none of the conventional digital cameras and video cameras with a built-in polarization filter have been developed with a focus on the user's shooting preferences, and it is not possible to execute highly satisfactory video shooting. It was.

  FIG. 1 is a block diagram of a digital camera (moving picture photographing apparatus) 100 according to the present invention. The digital camera 100 is positioned on the imaging optical axis Z inside the camera body 100B, and in order from the object side, a fixed lens (imaging optical system) 101, a movable focusing lens (imaging optical system) 102, and a CCD ( A moving image capturing unit) 103. The subject luminous flux that has entered through the fixed lens 101 and the focusing lens 102 forms an image on the imaging surface 103 a of the CCD 103 to capture the subject image. The focusing lens 102 is driven by a focusing lens driving unit 102a including a focusing motor, and moves in the photographing optical axis Z direction during focusing.

  The digital camera 100 includes a polarizing filter (rotating optical element) 110 between the fixed lens 101 and the focusing lens 102 in front of the CCD 103. The polarizing filter 110 is inserted between the insertion position located on the photographing optical axis Z (optical path of the photographing optical system) and the separation position separated from the photographing optical axis Z (optical path of the photographing optical system) by the insertion / removal driving mechanism 104. It is inserted / removed between. The insertion / removal drive mechanism 104 includes an insertion / removal drive motor (not shown) for driving the insertion / removal of the filter frame (not shown) holding the polarizing filter 110 between the insertion position and the removal position. And a Hall IC (not shown) provided in the drive motor. The output of the Hall IC varies depending on the rotation angle of the rotor of the insertion / removal drive motor. The specific mechanical configuration of the insertion / removal drive mechanism 104 is, for example, Japanese Patent Laid-Open No. 2006-337694, Japanese Patent Laid-Open No. 2006-337695, Japanese Patent Laid-Open No. 2007-3970, Japanese Patent Laid-Open No. 2007-3971, and Japanese Patent Laid-Open No. 2007-3971. Since it is well known as disclosed in Japanese Patent Application Laid-Open No. 2007-33481 and Japanese Patent Application Laid-Open No. 2007-225712, detailed description is omitted here.

  The polarizing filter 110 is driven by the rotation driving mechanism 111 at the insertion position, and is rotatable about the photographing optical axis Z. Although not shown, the rotation drive mechanism 111 includes a stepping motor that steps-drives the polarizing filter 110 by a predetermined angle and a motor driver that controls the rotation of the stepping motor.

  The polarization filter 110 is a linear polarization filter having a function of transmitting only light that vibrates in its own polarization direction (direction of the polarization grating). The linear polarizing filter has a polarization characteristic in which the polarization effect when the rotation angle is θ ° and the polarization effect when the rotation angle is θ + 180 ° are the same. That is, the rotation angle for one period in which the polarization effect of the linear polarization filter changes is 180 °. By rotating the polarizing filter 110 about the photographing optical axis Z and adjusting the polarization direction (direction of the polarization grating), the polarization state of the subject luminous flux incident on the CCD 103 is changed to reduce or eliminate the reflection of the subject. be able to.

  The digital camera 100 includes a control unit 120, an A / D converter 105, a signal processing circuit 106, an image recording unit 107, and an LCD monitor 108. The control unit 120 controls the overall functions of the digital camera 100. The A / D converter 105 converts the subject image formed on the imaging surface 103 a of the CCD 103 from an analog signal to a digital signal, and sends it to the signal processing circuit 106. The signal processing circuit 106 performs predetermined image processing on the digital signal sent from the A / D converter 105 to obtain an image signal. This image signal is recorded in the image recording unit 107 as a moving image via the control unit 120 and displayed on the LCD monitor 108.

  The digital camera 100 includes a filter insertion / removal switch (insertion / removal drive switch) 130 and a filter rotation switch (rotation drive switch) 140 as operation switches of the polarization filter 110. When the filter insertion / removal switch 130 is pressed, an insertion / removal drive instruction signal is input from the filter insertion / removal switch 130 to the control unit 120, and the control unit 120 sets the polarization filter 110 to the insertion position via the insertion / removal drive mechanism 104. It is inserted / removed between the disengagement positions. When the filter rotation switch 140 is pressed while the polarizing filter 110 is in the insertion position, a rotation drive instruction signal is input from the filter rotation switch 140 to the control unit 120, and the control unit 120 passes through the rotation drive mechanism 111. Then, the polarization filter 110 is rotationally driven.

  The digital camera 100 includes a moving image shooting mode setting unit (hereinafter abbreviated as “mode setting unit”) 150. The mode setting unit 150 can alternatively set the moving image shooting mode of the digital camera 100 from a plurality of modes set in advance to individually and flexibly correspond to the user's shooting preferences. The mode setting unit 150 is provided with a certain degree of freedom. For example, a mode in which the camera body 100B is provided as a physical operation switch or a mode in which the LCD monitor 108 is provided as a touch panel type operation switch is possible.

  FIG. 2 shows moving image shooting modes of the digital camera 100 that can be set by the mode setting unit 150. As shown in the figure, the moving image shooting mode of the digital camera 100 includes “polarization filter use permission mode (rotation optical element use permission mode, partial use prohibition mode)” and “polarization filter use prohibition mode (rotation optical element use prohibition). Mode, complete use prohibition mode) ”.

  The “polarization filter use prohibition mode” is a mode in which the polarization filter 110 is positioned at the separation position and the insertion drive is prohibited from the start to the end of moving image shooting.

  “Polarization filter use permission mode” allows the user to operate the filter insertion / removal switch 130 and the filter rotation switch 140 or automatically control the control unit 120 to shoot moving images with the polarization filter 110 positioned at the insertion position. It is a mode to do.

  “Polarization filter use permission mode” is further divided into “polarization filter non-removable rotation mode (partial use prohibition mode)”, “polarization filter insertion / removal non-rotatable mode (partial use prohibition mode)” and “polarization filter nonremovable mode” Branches to “rotatable mode (partially prohibited mode)”.

  In the “polarization filter non-removable rotation mode”, the polarization filter 110 is positioned at the insertion position from the start to the end of the moving image shooting, and the polarization filter 110 is driven by the insertion / removal drive mechanism 104 and driven by the rotation drive mechanism 104. In this mode, the rotation of the polarizing filter 110 is prohibited.

  In the “polarization filter insertion / removable non-rotatable mode”, the insertion / removal drive of the polarization filter 110 by the insertion / removal drive mechanism 104 is permitted from the start to the end of moving image shooting, and the rotation of the polarization filter 110 by the rotation drive mechanism 111 is rotated. This mode prohibits driving. The “polarization filter insertion / removable non-rotatable mode” further includes a “polarization filter manual insertion / removal mode” in which the polarization filter 110 is manually inserted / removed by operating the filter insertion / removal switch 130, and the polarization filter 110 is controlled by the control unit 120. It is divided into “polarization filter automatic insertion / removal mode” for automatic insertion / removal.

  In the “polarization filter detachable rotation possible mode”, the polarization filter 110 is positioned at the insertion position from the start to the end of the moving image shooting, and the rotation driving mechanism 111 at the insertion position is allowed to rotate. In addition, this is a mode in which the separation drive of the polarization filter 110 by the insertion / removal drive mechanism 104 is prohibited. The “polarization filter non-releasable rotation mode” further includes a “polarization filter manual rotation mode” in which the polarization filter 110 is manually rotated by the operation of the filter rotation switch 140, and the polarization filter 110 is automatically rotated by the control of the control unit 120. It is divided into “polarization filter automatic rotation mode”.

  The digital camera 100 includes a shutter button 160. The shutter button 160 is a button for performing an input operation for executing moving image capturing by the CCD 103. When the shutter button 160 is pressed while any moving image shooting mode is set by the mode setting unit 150, an instruction signal for starting moving image capturing by the CCD 103 is input from the shutter button 160 to the control unit 120. When the shutter button 160 is pressed during moving image shooting, an instruction signal for ending moving image shooting by the CCD 103 is input from the shutter button 160 to the control unit 120.

  The digital camera 100 includes photometric means (luminance signal acquisition unit) 170. The photometric unit 170 acquires the luminance signal of the subject image captured by the CCD 103 in real time and outputs it to the control unit 120.

  The digital camera 100 includes a microphone (voice recording unit) 180 that can perform voice recording simultaneously with moving image capturing by the CCD 103. Voice recording by the microphone 180 is controlled by the control unit 120. When the mode setting unit 150 is set to the “polarization filter use prohibition mode” or the “polarization filter use permission mode”, the control unit 120 performs voice recording with the microphone 180. To give permission. When the mode setting unit 150 is set to the “polarization filter use permission mode” of the “polarization filter insertion / removal non-rotatable mode” or the “polarization filter non-removable rotation mode”, the control unit 120 is configured to output the sound from the microphone 180. Prohibit recording. As described above, the sound recording by the microphone 180 is permitted in the moving image shooting mode in which the driving sound of the polarizing filter 110 cannot be generated, and the sound recording by the microphone 180 is prohibited in the moving image shooting mode in which the driving sound of the polarizing filter 110 can be generated. As a result, it is possible to prevent the driving sound of the polarizing filter 110 from being recorded even when voice recording is performed simultaneously with moving image shooting.

  The digital camera 100 includes an image processing unit 190 that performs image processing on a moving image of a subject captured by the CCD 103. When an operation error occurs in the insertion / removal drive of the polarization filter 110 by the insertion / removal drive mechanism 104 or the rotation drive of the polarization filter 110 by the rotation drive mechanism 111, the image processing unit 190 Extract only the part before the operation error occurred. Thereby, the image of the part disturbed by the operation error is not captured in the moving image, and a high-quality moving image can be obtained. When an operation error occurs in the insertion / removal drive of the polarization filter 110 by the insertion / removal drive mechanism 104 or the rotation drive of the polarization filter 110 by the rotation drive mechanism 111, the LCD monitor 108 is combined with the image processing by the image processing unit 190. A warning display and / or a warning sound may be generated.

  The control unit 120 controls the insertion / removal drive mechanism 104, the rotation drive mechanism 111, and the CCD 103 in different manners according to the moving image shooting mode set by the mode setting unit 150. Below, the control content of the control part 120 is demonstrated according to the case according to the moving image shooting mode which the mode setting part 150 has set.

When “Polarization Filter Use Prohibition Mode” is set When the shutter button 160 is pressed and an instruction signal for starting moving image capturing by the CCD 103 is input, the control unit 120, when the shutter button 160 is pressed, It is determined whether the polarizing filter 110 is located at the insertion position or the removal position.

  The control unit 120 determines whether the polarizing filter 110 is located at the insertion position or the separation position as follows. That is, an insertion detection sensor and a separation detection sensor made of a photo interrupter are provided at positions corresponding to the insertion position and the separation position of the polarizing filter 110, and a sensor passage piece (not shown) is formed in the filter frame that holds the polarizing filter 110. . The control unit 120 determines that the polarizing filter 110 is at the insertion position by the sensor passing piece entering between the light emitting unit and the light receiving unit of the insertion detection sensor and blocking light from the light emitting unit to the light receiving unit. When the sensor passage piece enters between the light emitting unit and the light receiving unit of the separation detection sensor and blocks the incidence of light from the light emitting unit to the light receiving unit, it is determined that the polarizing filter 110 is in the separation position.

  Alternatively, the control unit 120 reads the number of pulses given to the stepping motor of the polarization filter driving unit 111 that rotationally drives the polarization filter 110 to determine whether the polarization filter 110 is located at the insertion position or the separation position. be able to.

  Alternatively, the control unit 120 reads the output of the Hall IC of the insertion / removal drive mechanism 104 using the fact that the output of the Hall IC of the insertion / removal drive mechanism 104 varies according to the rotation angle of the rotor of the insertion / removal drive motor. Thus, it can be determined whether the polarizing filter 110 is located at the insertion position or the separation position.

  When it is determined that the polarizing filter 110 is in the insertion position when the shutter button 160 is pressed, the control unit 120 drives the polarizing filter 110 to the separation position via the insertion / removal driving mechanism 104. On the other hand, when the control unit 120 determines that the polarizing filter 110 is located at the separation position when the shutter button 160 is pressed, the control unit 120 positions the polarizing filter 110 as it is at the separation position. Then, the controller 120 starts moving image capturing by the CCD 103 while keeping the polarizing filter 110 in the detached position, and prohibits insertion / removal of the polarizing filter 110 by the insertion / removal drive mechanism 104 from the start to the end of moving image capturing. (The input operation of the filter insertion / removal switch 130 is invalidated).

When the “polarization filter detachment impossible rotation mode” is set, when the shutter button 160 is pressed and an instruction signal for starting moving image capturing by the CCD 103 is input, the control unit 120 is pressed. In FIG. 4, it is determined whether the polarizing filter 110 is located at the insertion position or the separation position.

  When the polarizing filter 110 is located at the insertion position when the shutter button 160 is pressed, the control unit 120 positions the polarizing filter 110 as it is at the insertion position. On the other hand, when the polarizing filter 110 is in the detached position when the shutter button 160 is pressed, the control unit 120 drives the polarizing filter 110 to the insertion position via the insertion / removal driving mechanism 104. Then, the control unit 120 starts moving image capturing by the CCD 103 while keeping the polarizing filter 110 at the insertion position. From the start to the end of moving image capturing, the control unit 120 drives and rotates the polarizing filter 110 by the insertion / removal drive mechanism 104. The rotation drive of the polarization filter 110 by the drive mechanism 104 is prohibited (input operation of the filter insertion / removal switch 130 and the filter rotation switch 140 is invalidated).

  For the rotation angle at the insertion position of the polarizing filter 110, a mode in which the setting can be changed in advance before the moving image capturing by the CCD 103 is executed, or a mode in which the rotation angle is set as a specific rotation angle of the digital camera 100 can be adopted. According to the former aspect, the user's convenience can be enhanced by changing the setting of the polarization effect obtained by the polarization filter 110 in advance. According to the latter aspect, by cutting the polarization component that vibrates in the horizontal direction, it is possible to shoot a moving image as if you are wearing a polarized sunglasses. In this case, the rotation angle of the polarization filter 110 corresponding to the polarization effect of the polarized sunglasses (the rotation angle of the polarization filter 110 that cuts the polarization component that vibrates in the horizontal direction) is stored in advance, and this is stored in the digital camera 100. It can be set as a unique rotation angle.

When “Polarizing Filter Insertion / Removable Non-Rotation Mode” is set When the shutter button 160 is pressed and an instruction signal for starting moving image capturing by the CCD 103 is input, the control unit 120 presses the shutter button 160. The insertion / removal position of the polarizing filter 110 at the time is maintained. Then, the control unit 120 starts moving image capturing by the CCD 103, permits insertion / removal driving of the polarization filter 110 by the insertion / removal drive mechanism 104 from the start to the end of moving image capturing, and allows the rotation of the polarization filter 110 to rotate by the rotation drive mechanism 111. The rotation drive is prohibited (the input operation of the filter insertion / removal switch 130 is validated and the input operation of the filter rotation switch 140 is invalidated).

  More specifically, when the mode setting unit 150 has set the “polarization filter manual insertion / removal mode”, the control unit 120 uses the insertion / removal drive mechanism 104 according to the input operation of the filter insertion / removal switch 130 by the user. The polarization filter 110 is inserted and removed.

  On the other hand, when the mode setting unit 150 has set the “polarization filter automatic insertion / removal mode”, the control unit 120 performs polarization using the insertion / removal drive mechanism 104 based on the luminance signal of the subject image acquired by the photometry unit 170. The filter 110 is automatically inserted and removed. For example, when the polarizing filter 110 is in the insertion position, the control unit 120 causes the luminance value of the subject image acquired by the photometry unit 170 to exceed a preset threshold value due to, for example, moving indoors from the outdoors or hiding the sun in clouds. When the voltage suddenly decreases, the insertion / removal drive mechanism 104 automatically drives the polarizing filter 110 to be detached. In addition, when the polarizing filter 110 is at the separation position, the control unit 120 determines that the luminance value of the subject image acquired by the photometric unit 170 is previously obtained by moving from indoors to the outdoors or by the sun appearing behind the clouds. When it becomes higher than the set threshold value, the polarization filter 110 is automatically inserted and driven by the insertion / removal drive mechanism 104.

  For the rotation angle at the insertion position of the polarizing filter 110, a mode in which the setting can be changed in advance before the moving image capturing by the CCD 103 is executed, or a mode in which the rotation angle is set as a specific rotation angle of the digital camera 100 can be adopted. According to the former aspect, the user's convenience can be enhanced by changing the setting of the polarization effect obtained by the polarization filter 110 in advance. According to the latter aspect, by cutting the polarization component that vibrates in the horizontal direction, it is possible to shoot a moving image as if you are wearing a polarized sunglasses. In this case, the rotation angle of the polarization filter 110 corresponding to the polarization effect of the polarized sunglasses (the rotation angle of the polarization filter 110 that cuts the polarization component that vibrates in the horizontal direction) is stored in advance, and this is stored in the digital camera 100. It can be set as a unique rotation angle.

When the “polarization filter detachable rotation enabling mode” is set, when the shutter button 160 is pressed and an instruction signal for starting moving image capturing by the CCD 103 is input, the control unit 120 is a point in time when the shutter button 160 is pressed. In FIG. 4, it is determined whether the polarizing filter 110 is located at the insertion position or the separation position.

  When the polarizing filter 110 is located at the insertion position when the shutter button 160 is pressed, the control unit 120 positions the polarizing filter 110 as it is at the insertion position. On the other hand, when the polarizing filter 110 is in the detached position when the shutter button 160 is pressed, the control unit 120 drives the polarizing filter 110 to the insertion position via the insertion / removal driving mechanism 104. Then, the control unit 120 starts moving image capturing by the CCD 103 while keeping the polarizing filter 110 at the insertion position, and permits rotation driving of the polarizing filter 110 by the rotation driving mechanism 104 from the start to the end of moving image capturing. Then, the separation drive of the polarization filter 110 by the insertion / removal drive mechanism 104 is prohibited (the input operation of the filter rotation switch 140 is validated and the input operation of the filter insertion / removal switch 130 is invalidated).

  More specifically, when the mode setting unit 150 has set the “polarization filter manual rotation mode”, the control unit 120 uses the rotation driving mechanism 111 to perform the polarization filter 110 according to the input operation of the filter rotation switch 140 by the user. Is driven to rotate.

  On the other hand, when the mode setting unit 150 has set the “polarization filter automatic rotation mode”, the control unit 120, for example, changes in the luminance value of the subject image acquired by the photometry unit 170, exposure conditions, and subject by object recognition Based on an evaluation value (index) such as a change, the rotation driving mechanism 111 automatically rotates the polarization filter 110. As a result, even when the subject changes or when the posture of the camera body 100B changes, it is possible to control the polarization effect to remain the same by automatically rotating the polarization filter 110.

  Regardless of manual rotation or automatic rotation, the control unit 120 rotates the polarization filter 110 by the rotation drive mechanism 111, and the polarization filter 110 when the CCD 103 is executing moving image imaging and when it is not. The speed at which 110 is driven to rotate can be changed. That is, the control unit 120 can rotationally drive the polarizing filter 110 at a speed dedicated to moving image shooting (for example, an ultra-high speed rotation or an ultra-low speed rotation) during moving image imaging by the CCD 103.

  Next, with reference to flowcharts of FIGS. 3 to 8, first to sixth embodiments of a moving image shooting method using the digital camera 100 according to the present invention will be described.

[First Embodiment]
The flowchart of FIG. 3 shows a moving image shooting method when the “polarization filter use prohibition mode” is set by the mode setting unit 150.

  First, the control unit 120 determines whether the user has pressed the shutter button 160 (step S1). When the shutter button 160 is not pressed (step S1: NO), the control unit 120 does not perform moving image capturing by the CCD 103.

  Then, the control unit 120 determines whether the polarizing filter 110 is located at the insertion position or the separation position when the shutter button 160 is pressed (step S3).

  When the control unit 120 determines that the polarizing filter 110 is located at the insertion position when the shutter button 160 is pressed, the control unit 120 drives the polarization filter 110 to the separation position via the insertion / removal driving mechanism 104 ( Step S4). On the other hand, when it is determined that the polarizing filter 110 is located at the separation position when the shutter button 160 is pressed, the control unit 120 positions the polarization filter 110 as it is at the separation position (step S5).

  The control unit 120 prohibits the insertion drive of the polarization filter 110 by the insertion / removal drive mechanism 104 while keeping the polarization filter 110 in the detached position (step S6), and starts moving image capturing by the CCD 103 (step S7).

  The control unit 120 determines whether or not the shutter button 160 has been pressed by the user during moving image capturing by the CCD 103 (step S8). As long as the shutter button 160 is not pressed (step S8: NO), the control unit 120 continues moving image capturing by the CCD 103.

  When the shutter button 160 is pressed during moving image capturing by the CCD 103 (step S8: YES), an instruction signal for ending moving image capturing by the CCD 103 is input from the shutter button 160 to the control unit 120 (step S9).

  Then, the control unit 120 permits the insertion drive of the polarizing filter 110 by the insertion / removal drive mechanism 104 after finishing the moving image capturing by the CCD 103 (step S10) (step S11).

  As described above, according to the moving image shooting method of the first embodiment of the present invention, it responds to a user's shooting preference that “the polarizing filter is exclusively used when shooting a still image and not used when shooting a movie”. be able to. In addition, the polarizing filter 110 does not move from the detached position during moving image shooting, and the polarizing filter 110 is not inserted or rotated due to an erroneous operation by the user. Therefore, the moving image is unintended and the moving image is spoiled. Can be prevented. Further, the vignetting does not occur because the filter frame holding the polarizing filter 110 blocks the photographing light beam during moving image photographing. Further, even when moving image shooting is performed using the automatic exposure function (AE function), the optimum exposure does not change during moving image shooting, so that suitable automatic exposure can be performed. In addition, excessive heat generation and increased power consumption during moving image shooting can be prevented.

[Second Embodiment]
The flowchart of FIG. 4 shows a moving image shooting method when the “polarization filter use permission mode” and the “polarization filter removal disabled rotation disabled mode” are set by the mode setting unit 150.

  First, the control unit 120 determines whether or not the user has pressed the shutter button 160 (step S21). When the shutter button 160 is not pressed (step S21: NO), the control unit 120 does not perform moving image imaging with the CCD 103.

  When the shutter button 160 is pressed (step S21: YES), an instruction signal for starting moving image capturing by the CCD 103 is input from the shutter button 160 to the control unit 120 (step S22).

  Then, the control unit 120 determines whether the polarizing filter 110 is located at the insertion position or the separation position when the shutter button 160 is pressed (step S23).

  When the controller 120 determines that the polarizing filter 110 is located at the insertion position when the shutter button 160 is pressed, the control unit 120 positions the polarizing filter 110 as it is at the insertion position (step S24). On the other hand, when the control unit 120 determines that the polarization filter 110 is in the detached position when the shutter button 160 is pressed, the control unit 120 drives the polarization filter 110 to the insertion position via the insertion / removal drive mechanism 104. (Step S25).

  The controller 120 keeps the polarizing filter 110 in the insertion position and prohibits the separation filter 110 from being detached and the rotation driving mechanism 111 from rotating and rotating the polarization filter 110 (step S26). Moving image capturing by the CCD 103 is started (step S27).

  The control unit 120 determines whether or not the user has pressed the shutter button 160 during moving image capturing by the CCD 103 (step S28). As long as the shutter button 160 is not pressed (step S28: NO), the control unit 120 continues moving image capturing by the CCD 103.

  When the shutter button 160 is pressed during moving image capturing by the CCD 103 (step S28: YES), an instruction signal for ending moving image capturing by the CCD 103 is input from the shutter button 160 to the control unit 120 (step S29).

  Then, after ending the moving image capturing by the CCD 103 (step S30), the control unit 120 permits the separation filter 110 to be detached by the insertion / removal drive mechanism 104 and the rotation drive mechanism 111 to rotate the polarization filter 110 (step S31). ).

  As described above, according to the moving image capturing method of the second embodiment of the present invention, “the polarizing sunglasses are worn by fixing the rotation angle of the polarizing filter to a rotation angle that cuts the polarization component that vibrates in the horizontal direction. It is possible to respond to the user's preference for taking a video as if they are watching. In addition, since the polarizing filter 110 does not move from the insertion position during moving image shooting and the polarizing filter 110 is not driven to be detached or rotated by an erroneous operation by the user, the moving image is unintended and the moving image is spoiled. Can be prevented. Further, the vignetting does not occur because the filter frame holding the polarizing filter 110 blocks the photographing light beam during moving image photographing. Further, even when moving image shooting is performed using the automatic exposure function (AE function), the optimum exposure does not change during moving image shooting, so that suitable automatic exposure can be performed. In addition, excessive heat generation and increased power consumption during moving image shooting can be prevented.

[Third Embodiment]
The flowchart of FIG. 5 shows a moving image shooting method when the “polarization filter manual insertion / removal mode” of the “polarization filter insertion permission / removable mode” of the “polarization filter use permission mode” is set by the mode setting unit 150. ing.

  First, the control unit 120 determines whether the user has pressed the shutter button 160 (step S41). When the shutter button 160 is not pressed (step S41: NO), the control unit 120 does not perform moving image imaging with the CCD 103.

  When the shutter button 160 is pressed (step S41: YES), an instruction signal for starting moving image capturing by the CCD 103 is input from the shutter button 160 to the control unit 120 (step S42).

  Then, the control unit 120 determines whether the polarizing filter 110 is located at the insertion position or the separation position when the shutter button 160 is pressed (step S43).

  When the controller 120 determines that the polarizing filter 110 is located at the insertion position when the shutter button 160 is pressed, the controller 120 positions the polarizing filter 110 as it is at the insertion position (step S44). On the other hand, when it is determined that the polarizing filter 110 is located at the separation position when the shutter button 160 is pressed, the control unit 120 positions the polarization filter 110 as it is at the separation position (step S45).

  The control unit 120 prohibits rotation driving of the polarization filter 110 by the rotation driving mechanism 111 while keeping the polarization filter 110 at the insertion position or the removal position (step S46), and starts moving image capturing by the CCD 103 (step S47). ).

  The control unit 120 determines whether or not the filter insertion / removal switch 130 has been pressed by the user during moving image capturing by the CCD 103 (step S48). When the filter insertion / removal switch 130 is pressed (step S48: YES), the control unit 120 drives the polarization filter 110 to be inserted / removed by the insertion / removal drive mechanism 104 (step S49). When the filter insertion / removal switch 130 has not been pressed (step S48: NO), the control unit 120 does not drive the polarization filter 110 by the insertion / removal drive mechanism 104 and continues moving image imaging by the CCD 103.

  Further, the control unit 120 determines whether or not the shutter button 160 is pressed by the user during the moving image capturing by the CCD 103 (step S50). The control unit 120 continues moving image capturing by the CCD 103 as long as the shutter button 160 is not pressed (step S50: NO).

  When the shutter button 160 is pressed during moving image capturing by the CCD 103 (step S50: YES), an instruction signal for ending moving image capturing by the CCD 103 is input from the shutter button 160 to the control unit 120 (step S51).

  Then, after ending the moving image imaging by the CCD 103 (step S52), the control unit 120 permits the rotation drive of the polarization filter 110 by the rotation drive mechanism 111 (step S53).

[Fourth Embodiment]
The flowchart of FIG. 6 shows a moving image shooting method when the “polarization filter automatic insertion / removal mode” of the “polarization filter insertion permission / removable mode” of the “polarization filter use permission mode” is set by the mode setting unit 150. ing.

  The flowchart of FIG. 6 has step S48 'instead of step S48 of the flowchart of FIG. 5, and other processing steps are the same as those of the flowchart of FIG. Therefore, only the processing steps related to step S48 'will be described, and description of other processing steps will be omitted.

  The control unit 120 determines whether or not the luminance value of the subject image acquired by the photometry unit 170 has changed beyond a preset threshold value after the moving image capturing by the CCD 103 is started (step S47 ′) (step S48 ′). ). When the luminance value of the subject image acquired by the photometry unit 170 changes beyond a preset threshold value (step S48 ′: YES), the control unit 120 automatically inserts and removes the polarizing filter 110 by the insertion / removal drive mechanism 104. Drive (step S49). For example, when the polarizing filter 110 is in the insertion position, the control unit 120 causes the luminance value of the subject image acquired by the photometry unit 170 to exceed a preset threshold value due to, for example, moving indoors from the outdoors or hiding the sun in clouds. When the voltage suddenly decreases, the insertion / removal drive mechanism 104 automatically drives the polarizing filter 110 to be detached. In addition, when the polarizing filter 110 is at the separation position, the control unit 120 determines that the luminance value of the subject image acquired by the photometric unit 170 is previously obtained by moving from indoors to the outdoors or by the sun appearing behind the clouds. When it becomes higher than the set threshold value, the polarization filter 110 is automatically inserted and driven by the insertion / removal drive mechanism 104. When the luminance value of the subject image acquired by the photometry unit 170 does not change beyond a preset threshold (step S48 ′: NO), the control unit 120 does not drive the polarization filter 110 to be inserted / removed by the insertion / removal drive mechanism 104. In addition, moving image capturing by the CCD is continued.

  As described above, according to the moving image capturing method of the third and fourth embodiments of the present invention, “I want to compare the polarization effect when using and not using the polarizing filter by inserting and removing the polarizing filter” or It is possible to respond to a user's preference for photographing that “I want to automatically drive the polarization filter when the subject suddenly becomes brighter or darker”. In addition, since the polarizing filter 110 is not rotationally driven by a user's erroneous operation, it is possible to prevent the moving image from being spoiled by performing moving image shooting not intended by the user. Further, even when moving image shooting is performed using the automatic exposure function (AE function), the polarization filter 110 does not rotate during moving image shooting so that the optimum exposure does not change. be able to. In addition, since the polarizing filter 110 can be inserted and removed, the range of exposure adjustment by automatic exposure on the digital camera 100 side can be widened. In addition, it is possible to prevent the polarization filter 110 from being rotationally driven during moving image shooting to cause excessive heat generation and increase in power consumption.

[Fifth Embodiment]
The flowchart of FIG. 7 shows a moving image capturing method when the “polarization filter manual rotation mode” of the “polarization filter unremovable rotation mode” of the “polarization filter use permission mode” is set by the mode setting unit 150. .

  First, the control unit 120 determines whether or not the user has pressed the shutter button 160 (step S61). When the shutter button 160 is not pressed (step S61: NO), the control unit 120 does not perform moving image imaging with the CCD 103.

  When the shutter button 160 is pressed (step S61: YES), an instruction signal for starting moving image capturing by the CCD 103 is input from the shutter button 160 to the control unit 120 (step S62).

  Then, the control unit 120 determines whether the polarizing filter 110 is located at the insertion position or the separation position when the shutter button 160 is pressed (step S63).

  When determining that the polarizing filter 110 is located at the insertion position when the shutter button 160 is pressed, the control unit 120 positions the polarizing filter 110 as it is at the insertion position (step S64). On the other hand, when the control unit 120 determines that the polarization filter 110 is in the detached position when the shutter button 160 is pressed, the control unit 120 drives the polarization filter 110 to the insertion position via the insertion / removal drive mechanism 104. (Step S65).

  The control unit 120 prohibits the separation filter 110 from being detached by the insertion / removal drive mechanism 104 while keeping the polarization filter 110 at the insertion position (step S66), and starts moving image capturing by the CCD 103 (step S67).

  The control unit 120 determines whether or not the filter rotation switch 140 is pressed by the user during the moving image capturing by the CCD 103 (step S68). When the filter rotation switch 140 is pressed (step S68: YES), the control unit 120 rotationally drives the polarizing filter 110 by the rotation drive mechanism 111 (step S69). When the filter rotation switch 140 is not pressed (step S68: NO), the control unit 120 does not rotate the polarizing filter 110 by the rotation driving mechanism 111 and continues moving image imaging by the CCD 103.

  Further, the control unit 120 determines whether or not the shutter button 160 has been pressed by the user during moving image capturing by the CCD 103 (step S70). As long as the shutter button 160 is not pressed (step S70: NO), the control unit 120 continues moving image capturing by the CCD 103.

  When the shutter button 160 is pressed during moving image capturing by the CCD 103 (step S70: YES), an instruction signal for ending moving image capturing by the CCD 103 is input from the shutter button 160 to the control unit 120 (step S71).

  Then, after ending the moving image capturing by the CCD 103 (step S72), the control unit 120 permits the polarization filter 110 to be detached by the insertion / removal drive mechanism 104 (step S73).

[Sixth Embodiment]
The flowchart of FIG. 8 shows a moving image shooting method when the “polarization filter automatic rotation mode” of the “polarization filter unremovable rotation mode” of the “polarization filter use permission mode” is set by the mode setting unit 150. .

  The flowchart of FIG. 8 has step S68 'instead of step S68 and step S69 of the flowchart of FIG. 7, and the other processing steps are the same as the flowchart of FIG. Therefore, only the processing steps related to step S68 'will be described, and description of other processing steps will be omitted.

  After the moving image capturing by the CCD 103 is started (step S67), the control unit 120 evaluates (indicates), for example, a change in the luminance value of the subject image acquired by the photometry unit 170, an exposure condition, and a subject change due to object recognition. Based on the above, the rotation driving mechanism 111 automatically rotates the polarization filter 110 (step S68 ′).

  As described above, according to the moving image capturing methods of the fifth and sixth embodiments of the present invention, “I want to perform moving image capturing while appropriately capturing changes in the polarization effect by rotating the polarization filter” or “ It is possible to respond to the user's preference for photographing that “the polarization filter is automatically driven to rotate according to evaluation values (indexes) such as a change in luminance value, exposure conditions, and subject change due to object recognition”. Further, since the polarizing filter 110 is not driven to be detached due to an erroneous operation by the user, it is possible to prevent the moving image from being spoiled by performing moving image shooting that is not intended by the user. Further, the vignetting does not occur because the filter frame holding the polarizing filter 110 blocks the photographing light beam during moving image photographing. In addition, it is possible to prevent the polarization filter 110 from being detached and driving during moving image shooting to cause excessive heat generation and increase in power consumption.

  As described above, in this embodiment, the mode setting unit 150 includes the polarization filter use permission mode that permits moving image shooting using the polarization filter 110 and the polarization filter use prohibition mode that prohibits movie shooting using the polarization filter 110. Depending on whether the mode setting unit 150 sets the polarization filter use permission mode or the polarization filter use prohibition mode, the control unit 120 sets any one of them, the insertion / removal drive mechanism 104, the rotation drive mechanism 111, and The CCD 103 is controlled in different ways. Thereby, it is possible to execute moving image shooting with a high degree of satisfaction in response to the user's shooting preferences individually and flexibly.

  In the above embodiment, the case where the moving image shooting apparatus according to the present invention is applied to the digital camera 100 is exemplified, but the moving image shooting apparatus according to the present invention can be applied to other shooting apparatuses such as a video camera.

  In the above embodiment, the case where the polarizing filter 110 is used as the rotating optical element has been described as an example. However, the rotating optical element only needs to provide a different imaging effect by rotating on the optical path of the imaging optical system. In addition to the polarizing filter, for example, a cross filter, a multi-surface effect filter, an ND filter, a half ND filter, etc. It is also possible to use.

  In the above embodiment, the case where a linear polarizing filter is used as the polarizing filter 110 has been described as an example. However, a circular polarizing filter can also be used. The circular polarization filter has a polarization characteristic in which the polarization effect when the rotation angle position is θ ° and the polarization effect when the rotation angle position is θ + 90 ° are the same.

  In the above embodiment, the case where there is some use restriction in the “polarization filter use permission mode” has been described as an example. However, the “polarization filter use permission mode (full use permission mode)” in which no use restriction exists. May be set. In this mode, the polarization filter 110 can be freely inserted and removed and rotated during moving image shooting. In this aspect, the mode setting unit 150 includes a “complete use permission mode”, a “polarization filter non-removable rotation mode (partial use prohibition mode)”, and a “polarization filter insertion / removal non-rotation mode (partial use). The “prohibition mode)” and “polarization filter non-removable rotatable mode (partial use prohibition mode)” can be set.

  In the above embodiment, the case where moving image shooting is executed when the shutter button 160 is pressed has been described as an example. However, the trigger for executing moving image shooting is not limited to this. For example, a mode in which a dedicated video shooting button is provided separately from the shutter button 160 and video shooting is executed when the video shooting button is pressed, a mode in which a video shooting execution function is assigned to various operation buttons by user customization, A mode in which moving image shooting is performed by selecting from a touch-panel menu using the LCD monitor 108 is possible.

  In the above embodiment, under the control of the control unit 120, in the moving image shooting mode in which the driving sound of the polarizing filter 110 cannot be generated, the sound recording by the microphone 180 is permitted and the moving image shooting in which the driving sound of the polarizing filter 110 can be generated. In the mode, the case where voice recording by the microphone 180 is prohibited has been described as an example. However, this embodiment is merely an example, and in the moving image shooting mode in which the driving sound of the polarizing filter 110 can be generated, the sound recording by the microphone 180 is prohibited in the moving image shooting mode in which the driving sound of the polarizing filter 110 cannot be generated. A mode of permitting voice recording by the microphone 180 is also possible.
