  Hereinafter, the present embodiment will be described with reference to the drawings. The imaging device 1 is a digital camera.

  The part related to imaging of the imaging device 1 includes an operation unit 10, a control unit 30, a shooting unit 50, a recording unit 70, and a display unit 90 (see FIG. 1). The operation unit 10 includes an exposure mode selection dial 11, a front adjustment dial 12, a rear adjustment dial 13, and a release button 14 (see FIGS. 2 and 3). The photographing unit 50 includes a lens 51 including an aperture, a shutter 52, an image sensor 53 such as a CCD, and an AE sensor 59. The information display unit 90 includes an optical finder 91 and first and second display units 92a and 92b. The front adjustment dial 12 and the rear adjustment dial 13 are so-called electronic dials that are disk-shaped operation members that can be rotated. A code plate (not shown) is provided on the back surface of the dial, and the control unit 30 sets parameters assigned to the dial according to the rotation direction and the rotation amount of the dial based on the signal from the code plate. It is configured to change the value.

  The subject image is captured by the image sensor 53 as an optical image via the lens 51. The captured image is displayed on the first display unit 92 a, and the captured image data is recorded in the recording unit 70. Exposure conditions at the time of imaging (setting of exposure factor values of shutter speed (exposure time), aperture value, and exposure sensitivity of the image sensor 53) are based on the setting of the operation unit 10 by the user and the setting state by the user. It is determined by at least one of the operations of the control unit 30.

  An optical image of the subject image via the lens 51 can be optically observed by the optical finder 91.

  The exposure mode selection dial 11 is a dial for selecting an exposure mode. The first program mode P1, the second program mode P2, the exposure sensitivity priority mode Sv, the shutter speed priority mode Tv, the aperture priority mode Av, the shutter speed and the aperture. A priority mode TAv, a manual mode M, a valve mode B, and a strobe tuning mode X are provided. However, the exposure mode selection means is not limited to a dial, and may be other selection means such as a switch.

  The exposure mode corresponding to the mark adjusted to the dial index position by rotating the exposure mode selection dial 11 becomes the exposure mode set in the imaging apparatus 1. In the exposure mode selection dial 11 in FIGS. 2 and 3, a black square mark as the first program mode P1, a P mark as the second program mode P2, an Sv mark as the exposure sensitivity priority mode Sv, and a Tv mark as the shutter speed priority mode Tv. The Av mark is displayed as the aperture priority mode Av, the TAv mark is displayed as the shutter speed and the aperture priority mode TAv, the M mark is displayed as the manual mode M, the B mark is displayed as the bulb mode B, and the X mark is displayed as the flash synchronization mode X. FIG. 2 shows a state where the Sv mark corresponding to the exposure sensitivity priority mode Sv is aligned with the dial index position, and FIG. 3 shows a state where the black square mark corresponding to the first program mode P1 is aligned with the dial index position. Show.

  In the first program mode P1, the shutter speed calculated by the control unit 30 so as to obtain an appropriate exposure based on the exposure value determined by the luminance value of the subject obtained during metering and a predetermined exposure sensitivity set in advance, This is an exposure mode for imaging using the aperture value.

  Specifically, the Ev value (exposure value) based on the brightness value (Bv value) of the subject and the exposure sensitivity (Sv value) of the image sensor 53 along a program line preset in the memory or the like of the imaging device 1. A combination of shutter speed (Tv value) and aperture value (Av value) corresponding to is determined (Bv + Sv = Ev = Tv + Av, see FIG. 4).

  Note that when the user is performing exposure correction setting, the Ev value is changed according to the exposure correction setting.

  The second program mode P2 is basically an exposure mode similar to the first program mode P1, but in the second program mode P2, the shutter speed is changed using the front adjustment dial 12, and the rear adjustment dial 13 is used. This is different from the first program mode P1 in that the aperture value can be changed using. When the shutter speed is changed, based on the changed shutter speed, the aperture value is calculated again by the control unit 30 so that proper exposure is obtained. When the aperture value is changed, based on the changed aperture value, the shutter speed is calculated again by the control unit 30 so that proper exposure is obtained. As described above, the first program mode P1 is different in that either one of the calculated shutter speed (Tv value) and aperture value (Av value) can be arbitrarily changed.

  In the exposure sensitivity priority mode Sv, the exposure sensitivity (Sv value) of the image sensor 53 set by the user, the luminance value (Bv value) of the subject obtained during photometry, and the exposure sensitivity (Sv value) of the set image sensor 53 are set. ) On the basis of the shutter speed (Tv value) and the aperture value (Av value) calculated so that the control unit 30 can obtain an appropriate exposure.

  Specifically, the Ev is based on the luminance value (Bv value) of the subject obtained during metering and the exposure sensitivity (Sv value) of the image sensor 53 that is arbitrarily set by the user operating the back adjustment dial 13. A value (exposure value) is calculated, and along the Ev line (diagonal line on the program diagram of FIG. 4) corresponding to the calculated Ev value and the program line, the shutter speed at which proper exposure is achieved and the aperture value A combination is determined, and this is an exposure mode in which imaging is performed with a combination of the shutter speed and the aperture value. In the case of a digital camera, the exposure sensitivity (Sv value) corresponds to the gain (gain) of the image signal output from the image sensor 53, and the controller 30 increases the gain of the image signal as the exposure sensitivity value increases. Set it high and perform the imaging operation. For this reason, the imaged image becomes a noisy image as the exposure sensitivity value is increased.

  Therefore, the exposure sensitivity priority mode Sv is suitable when the influence of the image quality due to the level of exposure sensitivity is taken into consideration for the drawing intention. If the luminance value (Bv value) of the subject is constant, the exposure value (Ev value) also changes as the exposure sensitivity (Sv value) is changed by manual operation. As a result, the calculated shutter speed ( The combination of (Tv value) and aperture value (Av value) also changes.

  In the exposure sensitivity priority mode Sv, the shutter speed can be changed using the front adjustment dial 12. When the shutter speed is changed, based on the changed shutter speed, the aperture value is calculated again by the control unit 30 so that proper exposure is obtained. That is, even if the combination of the calculated shutter speed and aperture value does not meet the user's will at the desired exposure sensitivity set by the user, either one of the exposure factors (here, the shutter speed) is It can be easily changed, and faithful imaging can be performed according to the drawing intention.

  The shutter speed priority mode Tv is based on an exposure value (Ev value) determined by the luminance value (Bv value) of the subject obtained during metering and the exposure sensitivity (Sv value) of a predetermined imaging element 53 set in advance. This is an exposure mode in which imaging is performed using the aperture value calculated by the control unit 30 so that a proper exposure can be obtained with respect to a shutter speed (Tv value) arbitrarily set by operating the front adjustment dial 12 by the user.

  The aperture priority mode Av is used based on the exposure value (Ev value) determined by the luminance value (Bv value) of the subject obtained during metering and the exposure sensitivity (Sv value) of a predetermined imaging device 53 set in advance. The user operates the rear adjustment dial 13 to perform exposure using the shutter speed (Tv value) calculated by the control unit 30 so as to obtain an appropriate exposure for an arbitrarily set aperture value (Av value). Mode.

  The shutter speed and aperture priority mode TAv are the shutter speed and aperture value set by the user, and the exposure sensitivity of the image sensor 53 calculated by the control unit so as to obtain an appropriate exposure based on the luminance value obtained during photometry. This is the exposure mode for capturing images using.

  Specifically, based on the shutter speed (Tv value) and the aperture value (Av value) set by the user, an exposure value (Ev value) that provides proper exposure during imaging is calculated (Ev = Tv + Av). . Based on the luminance value (Bv value) obtained during photometry, the exposure sensitivity (Sv value) of the image sensor 53 corresponding to the calculated exposure value (Ev value) is determined (Sv = Ev−Bv).

  The manual mode M is an exposure mode in which imaging is performed using the shutter speed, the aperture value, and the exposure sensitivity of the image sensor 53 set by the user.

  The valve mode B is an exposure mode in which an image is taken while the release button 14 is fully pressed using the aperture value set by the user and the exposure sensitivity of the image sensor 53.

  The strobe tuning mode X is an exposure mode in which imaging is performed using the aperture value set by the user, the exposure sensitivity of the image sensor 53, and the shutter speed that can be synchronized with the strobe light emission set in the imaging device 1 in advance.

  The front adjustment dial 12 is an electronic dial disposed on the front grip portion of the image pickup apparatus 1 and is rotated in the second program mode by rotating the user's right index finger while holding the image pickup apparatus 1. In P2, the shutter speed priority mode Tv, the shutter speed and aperture priority mode TAv, and the manual mode M, the shutter speed is changed. However, the front adjustment dial 12 may be used for other adjustment operations (exposure correction setting, frame number setting in the auto bracket function, etc.).

  The back adjustment dial 13 is an electronic dial disposed on the right side of the back surface of the image pickup apparatus 1 and is rotated in the second program mode by the user holding the image pickup apparatus 1 and rotating it with the thumb of the user's right hand. In P2, aperture priority mode Av, shutter speed and aperture priority mode TAv, manual mode M, bulb mode B, and strobe tuning mode X, the aperture value is changed. In the exposure sensitivity priority mode Sv, the exposure sensitivity of the image sensor 53 is changed. Is changed. However, the rear adjustment dial 13 may be used for other adjustment operations (such as a correction width in the auto bracket function).

  When the release button 14 is half-pressed, a photometry switch (not shown) is turned on, and photometry by the AE sensor 59 and distance measurement and focusing operation by the AF sensor (not shown) are performed. In the first program mode P1, the second program mode P2, the exposure sensitivity priority mode Sv, the shutter speed priority mode Tv, the aperture priority mode Av, the shutter speed and the aperture priority mode TAv, the brightness value of the subject image obtained by photometry is set. Based on this, an exposure condition such as a shutter speed is calculated by the control unit 30.

  When the release button 14 is fully pressed, a release switch (not shown) is turned on and imaging is performed. The control unit 30 performs an imaging operation based on the values of exposure factors such as shutter speed, aperture value, and exposure sensitivity that are automatically calculated or arbitrarily set. An image corresponding to the image data obtained by imaging is displayed on the first display unit 92a, and the image data is recorded in the recording unit 70.

  The control unit 30 drives the AE sensor 59 to calculate the luminance value of the subject and controls the exposure conditions at the time of photometry corresponding to the exposure mode. When the exposure condition is calculated, any one of the calculated shutter speed, aperture value, and exposure sensitivity of the image sensor 53 (exposure factor value) is outside the range set by the imaging apparatus 1 (shutter speed range). Outside, aperture value range, exposure sensitivity range), it is assumed that proper exposure cannot be obtained, and a warning display is made using the display unit in the optical viewfinder 91 or the first and second display units 91a and 92a. Do.

  For example, in the exposure sensitivity priority mode Sv, when imaging a subject with a high luminance value, when the exposure sensitivity of the image sensor 53 set by the user is high (when the Sv value is large), the shutter of the imaging device 1 is used as the shutter speed. When a value exceeding the upper limit of the speed (Tv value) is calculated, and a value (Av value) higher than the aperture value of the lens 51 attached to the imaging apparatus 1 in the narrowed state is calculated as the aperture value, In the imaging apparatus 1, the shutter speed (Tv value) is set to the upper limit value, and the aperture value (Av value) is set to the aperture value in a state where the lens 51 is stopped, so that an appropriate exposure can be obtained when the imaging operation is performed as it is. Absent. In this case, appropriate exposure can be obtained for the user by blinking the first exposure sensitivity display area 91a1 of the exposure condition display area 91a of the optical viewfinder 91 or the second exposure sensitivity display area 92b1 of the second display unit 92b. Therefore, an operation for changing the exposure sensitivity of the image pickup device 53 (in this case, lowering the Sv value) is prompted.

  The optical viewfinder 91 is a viewfinder for observing an optical image of the subject image through the lens 51 and an exposure condition set by the user or calculated by photometry by looking into it with one eye of the user. The optical viewfinder 91 has a region (not shown) for displaying an optical image and an exposure condition display region 91a for displaying exposure conditions such as a shutter speed (see FIG. 6). The exposure condition display area 91a includes a first exposure sensitivity display area 91a1 indicating the exposure sensitivity of the image sensor 53, a first shutter speed display area 91a2 indicating the shutter speed, and a first aperture value display area 91a3 indicating the aperture value.

  The first display unit 92a is a display device arranged on the back surface of the imaging device 1, and displays an image obtained by imaging and displays information related to function settings such as white balance. The second display unit 92b is a display device arranged on the upper surface of the imaging device 1, and displays a function setting state related to image processing and recording such as exposure conditions and white balance. The second display unit 92b includes a second exposure sensitivity display area 92b1 indicating the exposure sensitivity of the image sensor 53, a second shutter speed display area 92b2 indicating the shutter speed, and a second aperture value display area 92b3 indicating the aperture value ( (See FIG. 5).

  In the present embodiment, as one of the exposure modes selected by the user, the exposure sensitivity priority mode Sv for manually setting the exposure sensitivity of the image sensor 53 and calculating the shutter speed and the aperture value based on the set exposure sensitivity is set. Have. As a result, it is possible to calculate an appropriate exposure condition (shutter speed, aperture value) according to the exposure sensitivity of the image sensor 53 and to capture an image.

  For example, it is used when shooting with the exposure sensitivity of the image sensor 53 lowered in an environment where priority is given to obtaining an image with less noise.

  Further, as a means for setting the exposure sensitivity of the image sensor 53, a rear adjustment dial 13 disposed on the rear surface of the image pickup apparatus 1 is used, and the exposure sensitivity value changed by the rear adjustment dial 13 is expressed by the optical viewfinder 91. , And the first and second display portions 92a and 92b. Therefore, if the exposure sensitivity priority mode Sv is set, the exposure sensitivity value of the image sensor 53 can be changed by only one operation of rotating the back adjustment dial 13.

  Conventionally, there is an imaging apparatus that includes an exposure sensitivity adjustment function of the imaging element 53 and a program mode as one of the exposure modes. Therefore, it is possible to perform an operation similar to the exposure sensitivity priority mode Sv of the present embodiment by adjusting the exposure sensitivity of the image sensor 53 with the program mode set. However, in this case, in order to adjust the exposure sensitivity of the image sensor 53, a button for starting exposure sensitivity adjustment, an up / down key or dial for changing the exposure sensitivity, and a key for determining or canceling the setting are used. Therefore, the value of the exposure sensitivity of the image sensor 53 cannot be changed by only one operation.

  The exposure mode selection dial 11 used for setting the exposure sensitivity priority mode Sv is a dial used for selecting an exposure mode such as the shutter speed priority mode Tv. This dial is used to set an aperture value in the priority mode Av or the like. Therefore, the exposure sensitivity priority mode Sv is added to the exposure mode selection dial, and the function for setting the exposure sensitivity in the exposure sensitivity priority mode Sv is added to the dial for selecting an aperture value and the like. It becomes possible to carry out, and it is not necessary to provide a new operation key for the exposure sensitivity priority mode Sv. Further, the use of the rear adjustment dial 13 can change the exposure sensitivity in the same manner as the aperture value change in the aperture priority mode Av, and the operation is not complicated for the user. That is, for the user, the operation for manually setting an arbitrary exposure sensitivity can be performed in the same manner as the operation for manually setting other shutter speeds and aperture values, so that it is possible to easily and quickly perform imaging with a desired exposure sensitivity. The action can be performed.
