Description

  The present invention relates to an imaging device and a program thereof, and more particularly to an imaging device having a zoom function, a bracketing imaging function, and the like, and a program thereof.

2. Description of the Related Art Conventionally, digital cameras equipped with a zoom function that manipulates the magnification of a lens according to a zoom operation have been widely used. Thus, the angle of view of the image can be changed by the user performing a zoom operation.
In addition, digital cameras equipped with a bracketing shooting function have become widespread, which allows users to select images that they like later by changing the shooting conditions, etc. An appropriate image can be obtained.

Patent Document 1 listed below discloses an invention that is an interlocking mechanism for a zoom lens device. Specifically, by controlling the ratio of the subject distance and the focal length to be constant or proportional, the size of the subject in the image is kept substantially constant even when the shooting distance and the angle of view change.
Patent Document 2 below discloses an invention called an electronic still camera. Specifically, when a user performs a predetermined operation, a plurality of images with different shooting conditions are shot at the time of a shutter operation, sequentially recorded in an image memory, and displayed on a monitor, and then a selected image is recorded on a recording medium. That's it.

Patent gazette Japanese Patent Publication No. 60-001602 (refer to paragraph (2), right column 4, line 38 to paragraph (5), right column 10, line 8)

Japanese Published Patent Application No. Hei 2-172368 (see lower right column, item 9, line 1 to upper right column, item 15, line 2)

However, the conventional digital camera has the following problems.
(1) With the conventional zoom function, even if you intend to shoot a subject with the same angle of view, the angle of view of the image and the size of the subject image change each time you shoot depending on the zoom magnification, focal length, and subject distance. When I tried to shoot a subject image with the same angle of view and the same size, it didn't go well.
Therefore, if you want to combine multiple images later, try to combine panoramas, or if you want to capture multiple scenes and buildings in the same size from the same location, or if you want to have a predetermined image size, Therefore, it is necessary to make fine adjustments such as trimming by image processing and enlargement / reduction by image processing or the like, which requires a lot of time and labor and is troublesome. In addition, there is a problem that those who are unfamiliar with personal computers cannot make such fine adjustments and have to give up.

(2) According to the technique described in Patent Document 1, the size of the subject in the image can be kept substantially constant by keeping the ratio of the subject distance and the focal length constant or proportional. When the subject moves, there is a problem that the size of the subject changes. Also, if distance measurement is not possible or fails in a dark place, zooming with zooming operation cannot be performed, and the focal length and magnification are fixed depending on the subject distance. There was also a problem that photography was not possible at a magnification.

(3) In addition, there are cameras and devices that have a bracketing function that continuously captures several photos at once by changing the shooting conditions such as exposure, white balance, and focus position little by little. There was no digital camera equipped with a zoom function and a bracketing function that can arbitrarily set the angle of view.
As a result, the bracketing interval may be larger or smaller than the user's desired interval, and there is a problem that the user cannot actually obtain the desired image even when bracketing shooting is performed. .
Further, such a problem cannot be solved by the technique described in Patent Document 2 described above.
(4) Further, when the user performs shooting, there is a problem in that appropriate shooting cannot be performed because the current angle of view cannot be recognized.

Hereinafter, the present embodiment will be described in detail with reference to the drawings.
[First embodiment]
A. Configuration of Digital Camera FIG. 1 is a block diagram showing a schematic electrical configuration of a digital camera 1 that implements the photographing apparatus of the present invention.
The digital camera 1 includes a CCD 2, a DSP / CPU 3, a TG (timing generator) 4, a unit circuit 5, a DRAM 6, a flash memory 7, a ROM 8, a key input unit 9, an image display unit 10, a card I / F 11, a motor drive circuit 13, A focus lens 14 and a zoom lens 15 are provided, and a memory card 12 detachably attached to a card slot of the digital camera 1 (not shown) is connected to the card I / F 11.

  The motor drive circuit 13 includes a focus motor and a zoom motor that drive the focus lens 14 and the zoom lens 15 in the optical axis direction, and a motor driver that drives the focus motor and the zoom motor, respectively, according to a control signal sent from the DSP / CPU 3. (Not shown).

  The CCD 2 (imaging device) photoelectrically converts the projected subject and outputs it to the unit circuit 5 as an imaging signal. The CCD 2 is driven in accordance with a predetermined frequency timing signal generated by the TG 4. A unit circuit 5 is connected to TG4. The unit circuit 5 includes a CDS (Correlated Double Sampling) circuit that holds the image pickup signal output from the CCD 2 by correlated double sampling, a gain adjustment amplifier (AGC) that amplifies the image pickup signal, and a digital signal of the amplified image pickup signal. The output signal of the CCD 2 is sent to the DSP / CPU 3 as a digital signal through the unit circuit 5.

The image display unit 10 includes a color LCD and its driving circuit, and displays a subject imaged by the CCD 2 as a through image when in a shooting standby state, and is read out from the storage memory card 12 when reproducing a recorded image. Display the expanded recorded image. In addition, an angle of view θ described later, an angle of view θi for each unit scale, a subject range X, a subject range Xi, and the like are displayed. The image display unit 10 functions as display means of the present invention.
The key input unit 9 includes a plurality of operation keys such as a shutter button that can be pressed halfway and fully, an execution key, a cancel key, a SET key, a cross key, an automatic zoom button, a manual zoom button, and a mode setting key. An operation signal corresponding to the user's key operation is output to the DSP / CPU 3. The key input unit 9 functions as input means, first selection means, and second selection means of the present invention.
The DRAM 6 is used as a buffer memory that temporarily stores digitized subject image data after being imaged by the CCD 2, and is also used as a working memory for the DSP / CPU 3.

  The DSP / CPU 3 is a one-chip microcomputer that has various digital signal processing functions including image file compression / decompression processing and controls each part of the electronic camera 21. The flash memory 7 and the ROM 8 store control programs necessary for each part of the DSP / CPU 3, that is, programs necessary for various controls including AE and AF, and necessary data. Operates in accordance with the program to function as the photographing apparatus of the present invention.

In the AF process, when the user operates the shutter button of the key input unit 9, a key input signal corresponding to the operation is output to the DSP / CPU 3. When the DSP / CPU 3 receives the signal, the DSP / CPU 3 sends a control signal to the motor drive circuit 13, and the motor drive circuit 13 moves the focus lens 14 from the lens end to the lens end within the movable range in accordance with the control signal.
The CCD 2 photoelectrically converts a subject projected via the focus lens 14 and the zoom lens 15 and outputs it as an imaging signal to the unit circuit 5, and the unit circuit 5 sends a digital signal to the DSP / CPU 3. The DSP / CPU 3 extracts a high frequency component included in the digital signal sent from the unit circuit 4, interprets the high frequency component, and sends a control signal to the motor drive circuit 13. Then, the motor drive circuit 13 moves the focus lens 14 in accordance with the control signal.

B. Hereinafter, the functions of the respective configurations that are the characteristics of the digital camera 1 in the present embodiment will be described.
When set to the still image shooting mode, the DSP / CPU 3 starts imaging by the CCD 2 and displays a through image of the subject on the image display unit 10. Then, it is determined whether or not the shutter button has been half-pressed by the user's operation of the key input unit 9. This determination is made based on whether or not an operation signal corresponding to half-pressing of the shutter button is sent from the key input unit 9.

If the shutter button is not half-pressed, it is determined whether or not a zoom operation has been performed.
This determination is made based on whether or not an operation signal corresponding to the operation of the automatic zoom button and the manual zoom button is sent from the key input unit 9. The automatic zoom button automatically zooms by moving the zoom lens 15 so that the angle of view θ of the image becomes the angle set by the user or the subject range X of the image becomes the distance set by the user. It is a zoom button for. The manual zoom button is a zoom button for moving the zoom lens 15.

When the DSP / CPU 3 determines that there is a zoom operation, the DSP / CPU 3 determines whether it is automatic zoom. This determination is based on whether the received operation signal is an operation signal corresponding to the operation of the automatic zoom button or an operation signal corresponding to the operation of the manual zoom button, and is an operation signal corresponding to the operation of the automatic zoom button. In this case, it is determined that the zoom is automatic.
If the DSP / CPU 3 determines that the zoom is automatic, it sets the angle of view θ or the subject range X. In this setting, the angle input by the user is set as the angle of view θ, or the input distance is set as the subject range X. This function corresponds to the setting means of the present invention. Here, the angle of view refers to an angle at which the zoom lens 15 can capture, and the subject range refers to the range and size of the subject imaged by the CCD 2.
On the other hand, if it is determined that the zoom is not automatic zoom, that is, if it is determined that the zoom is manual zoom, normal zoom processing is performed.

When the DSP / CPU 3 determines that the zoom is automatic and sets the angle of view θ or the subject range X, the DSP / CPU 3 acquires a zoom value corresponding to the angle of view θ or the subject range X. This function corresponds to the acquisition means of the present invention.
Then, the DSP / CPU 3 operates the zoom function so that the acquired zoom value is obtained. This function corresponds to the control means of the present invention.
Here, as a method of acquiring the zoom value corresponding to the angle of view θ or the subject range X, the zoom value may be acquired by calculating the focal length f corresponding to the angle of view θ or the subject range X. This function corresponds to the calculation means of the present invention.
Further, as a method of operating the zoom function so as to obtain the acquired zoom value, the zoom lens 15 may be driven so as to obtain the calculated focal length f. This function corresponds to the drive control means of the present invention.
As a method for acquiring the zoom value in the case of the digital zoom, a zoom value that obtains the angle of view θ or the subject range X is acquired, and as a method for operating the zoom function, the digital zoom is performed so that the acquired zoom value is obtained. May be performed.

The relationship between the focal length f and the angle of view θ and the relationship between the focal length f, the subject distance and the subject range X will be described with reference to FIG.
The distance from the CCD 2 to the zoom lens 15 is the focal length f, and the focal length f and the angle of view θ change depending on the position of the zoom lens 15. X ′ is the horizontal imaging range (length) of the CCD 2, and Y ′ is the vertical imaging range (length) of the CCD 2. The focal length f is obtained by a trigonometric function from the set angle of view θ and the imaging range X ′. Formula 1 is a formula showing the relationship among the angle of view θ, the imaging range X ′, and the focal length f.

The distance L is a distance from the zoom lens 15 to the subject (subject distance), and X is a subject range (a horizontal range in which the subject can be imaged). The focal length f is determined by the ratio from the set subject range X, subject distance (distance L), and imaging range X ′. Expression 2 is an expression showing the relationship between the subject range X, the subject distance, the imaging range X ′, and the focal length f.
Regarding the distance L, since the AF operation is performed at a fixed timing (time change, signal component change, etc.) during through image display, the distance L to the subject is obtained from the position of the focus lens. Further, the distance L to the subject may be obtained by an infrared method or a phase difference method, or may be a distance input by a user by eye measurement. That is, any method that can measure the distance to the subject is acceptable.
The imaging ranges X ′ and Y ′ are recorded in advance in the ROM 8 or the like.

  Then, the DSP / CPU 3 determines whether or not the shutter button is half-pressed. If the shutter button is not half-pressed, the above operation is repeated. If the shutter button is half-pressed, the AE / AF is performed on the subject. Process. The AE process refers to the amount of light applied to the CCD 2, and the AF process refers to automatically focusing on the subject. A typical AF process is a contrast detection method. In the contrast detection method, the focus lens 14 is moved from end to end, the contrast of the CCD 2 at that time is converted into an electric signal, the waveform is analyzed, that is, the focus lens 14 is positioned at the lens position where the high-frequency component is the largest. Move the to adjust the focus. Note that AF processing may be performed by a phase difference detection method, an active method using infrared rays, or the like.

When the AE and AF processes are performed, a through image of the subject imaged by the CCD 2 via the focus lens 14 and the zoom lens 15 is displayed on the image display unit 10, and the angle of view θ is calculated from the focal length f and the imaging range X ′. The subject range X is calculated from the subject distance, the focal length f, and the imaging range X ′ and stored in the DRAM 6. The function of calculating the angle of view θ functions as an angle of view calculation unit of the present invention, and the function of calculating the subject range X functions as a range calculation unit of the present invention.
The angle of view θ is calculated from the focal length f and the imaging range X ′ according to Equation 3, and the subject range X is calculated from the focal length f, the subject distance, and the imaging range X ′ according to Equation 4. Expression 3 is a modification of Expression 1, and Expression 4 is a modification of Expression 2.
When the user has input an angle of view or subject range by automatic zooming, the angle of view or subject range input as it is may be stored in the DRAM 6 without calculating the angle of view θ or subject range X. .

  When the DSP / CPU 3 calculates the angle of view θ and the subject range X, it corresponds to the angle of view θi (i = 5, 10, 15, etc.) and subject range Xi (i = 25, 50, etc.) for each scale unit. The respective imaging positions X′i are calculated and stored in the DRAM 6. The function of calculating the imaging position X′i corresponding to the angle of view θi for each graduation unit calculates the imaging position X′i corresponding to the subject range Xi for each graduation unit to the angle of view position calculation means of the present invention. The function corresponds to the range position calculation means of the present invention.

Here, the angle of view θi for each scale unit means, for example, an angle of view having a scale of θi = 5 °, 10 °, 15 °, 20 °, etc., where the calculated angle of view θ is 23 °. The calculation of the imaging position X′i corresponding to the angle of view θi for each scale unit means, for example, calculating the position on the CCD 2 corresponding to the angle of view of 5 °, 10 °, etc. of the captured image.
FIG. 3C is a diagram simply showing the relationship between the angle of view θi for each unit scale and the imaging position X′i. When the angle of view θi of the unit scale is 20 °, it can be seen that the position on the CCD 2 corresponding to the angle of view is the position of X′i (20). Further, when the angle of view θi = 10 ° of the unit scale, it can be seen that the position on the CCD 2 corresponding to the angle of view is the position of X′i (10). The overall angle of view θ is 23 °.
The imaging position X′i corresponding to the angle of view θi for each scale unit can be obtained by the relational expression of Expression 5.

Similarly, the subject range Xi for each scale unit is, for example, when the calculated subject range X is 150 m and the center of the CCD 2 is 0 m, the left and right ends are 75 m. At this time, the range is a scale with a distance of 25 m and 50 m from the center to the left and right. The calculation of the imaging position X′i corresponding to the subject range Xi for each scale unit is, for example, from the center of the captured image to the left and right. This means that a range on the CCD 2 corresponding to a range of 25 m, 50 m, etc. is calculated.
FIG. 3D is a diagram simply showing the relationship between the subject range Xi and the imaging position X′i for each unit scale. When the subject range Xi of the unit scale is a range (50 m) that is 25 m apart from the center, it can be seen that the range on the CCD 2 corresponding to the range is a range between X′i (25 m). Further, when the subject range Xi of the unit scale is a range (100 m) that is 50 m away from the center, it can be seen that the range on the CCD 2 corresponding to the range is a range between X′i (50 m). Note that the entire subject range is 150 m.
The imaging position X′i corresponding to the distance Xi for each scale unit can be obtained by the relational expression of Expression 6.

Then, the DSP / CPU 3 causes the image display unit 10 to display the calculated field angle θ, the subject range X, the field angle θi for each scale unit, and the subject range Xi for each scale unit together with the through image of the subject that has been imaged. The function of causing the image display unit 10 to display the angle of view θ and the angle of view θi for each unit scale together with the through image is displayed on the image display unit 10 by the first display control unit of the present invention. The function displayed on the screen corresponds to the second display control means of the present invention.
FIG. 2B is a diagram showing the state at that time (however, for convenience of explanation, display of a through image of the captured subject is omitted). Although θ = 23 ° is shown at the upper center of the image display unit 10, this indicates the calculated angle of view θ. Further, X = 150 in the upper right portion indicates the calculated subject range X (horizontal length of the imaged subject), and Y = 112 in the upper left portion indicates the vertical length of the imaged subject. Indicates the length. The length of Y can be obtained from the ratio between the imaging range X ′ of the CCD 2 and the imaging range Y ′ of the CCD 2.
Note that the through image of the captured subject is displayed in a frame 20 (hereinafter referred to as an image display frame 20).

Further, a horizontal scale of the subject range is displayed at the bottom of FIG. 2B, and 0 is displayed at the center and 25 and 50 are displayed at the left and right. 25 and 50 indicate positions that are 25 m and 50 m away from the center 0, respectively. The scale position is determined by the imaging position X′i corresponding to the calculated subject range Xi for each scale unit.
Similarly, in FIG. 2B, a vertical scale of the subject range is displayed on the left side, 0 is displayed at the center, and 25 and 50 are displayed above and below the center. 25 and 50 indicate that the height is 25 and 50 m away from the center 0, respectively. The position of the scale can be obtained from the imaging range X ′ of the CCD 2 and the imaging range Y ′ of the CCD 2 and the calculated imaging position X′i.

In the image display frame 20, a scale of the angle of view is displayed on the diagonal line from the upper right to the lower left, and angles of 5 °, 10 °, 15 °, and 20 ° from the center of the image display unit 10 are displayed. ing. Further, a horizontally long rectangle is displayed immediately below 5 °, 10 °, etc., and this angle display represents the angle of view of the image in the horizontally long rectangle. That is, 5 ° indicates that the angle of view of the image in the horizontally long rectangle immediately below is 5 °. Similarly, 10 °, 15 °, and 20 ° indicate that the angles of view of the images in the horizontally long rectangles immediately below are 10 °, 15 °, and 20 °, respectively. The position of the horizontally long rectangle is determined by the imaging position X′i corresponding to the calculated angle of view θi for each unit scale.
Although the description has been given using the optical zoom, even in the case of the digital zoom, the field angle θ, the subject range X, the field angle θi for each unit scale, and the subject range Xi for each unit scale are calculated and the through of the subject is calculated. You may make it display on the image display part 10 with an image.

When the DSP / CPU 3 displays the angle of view θ, the angle of view θi, the subject range X, and the subject range Xi on the image display unit 10, the DSP / CPU 3 determines whether or not the shutter button has been fully pressed.
When the shutter button is fully pressed, a still image shooting process (shooting means) is performed, and shooting conditions (including the angle of view θ and the focal length f) are recorded in the memory card 12 (recording means) together with image data obtained by shooting. To do. This function corresponds to the recording control means of the present invention.
On the other hand, if the shutter button has not been fully pressed, it is determined whether or not the shutter button has been pressed halfway. If it is determined that the half-press is not continued, that is, it is determined that the half-press is released, the aperture or shutter speed set by the AE / AF processing is canceled and a through image is displayed.
On the other hand, when the half-press is continued, the through image is displayed until the shutter button is fully pressed.

C. Operation of Digital Camera 1 The operation of the digital camera 1 in the first embodiment will be described with reference to the flowchart of FIG.
When the still image shooting mode is set by the user's operation of the key input unit 9, imaging by the CCD 2 is started in step S 1, and a through image of the subject is displayed on the image display unit 10.

Next, the process proceeds to step S2, and it is determined whether or not the shutter button is half-pressed by the user. If the shutter button has been pressed, the process proceeds to step S9. If the shutter button has not been pressed halfway, the process proceeds to step S3.
In step S3, it is determined whether a zoom operation has been performed. This determination is made based on whether or not an operation signal corresponding to the operation of the automatic zoom button or the manual zoom button has been sent by the user.
When the zoom operation is performed, the process proceeds to step S4, and when the zoom operation is not performed, the process returns to step S2.

In step S4, it is determined whether automatic zooming has been performed. This determination is made when the operation signal corresponding to the operation of the automatic zoom button is sent, and is determined to be automatic zooming, and when the operation signal corresponding to the operation of the manual zoom button is sent, it is not automatic zooming. to decide.
If it is determined that the zoom is an automatic zoom, the process proceeds to step S5. If it is determined that the zoom is not an automatic zoom, the process proceeds to step S8, a normal zoom process is performed, and the process returns to step S2. The normal zoom processing means that the subject is zoomed by moving the zoom lens 15 by the user's operation of the manual zoom button.
If it is determined that automatic zooming is performed and the process proceeds to step S5, the angle input by the user is set as the field angle θ of the image or the input distance is set as the subject range X of the image.

Here, input of the user's angle or distance will be described.
If it is determined in step S4 that automatic zooming is in effect, the image display portion 10 has characters such as “Please enter the angle of view or subject range” and an image below it as shown in FIG. A field for entering the corner and the subject range is displayed. It can also be seen that the field for entering the angle of view is covered with diagonal lines. This indicates that the angle of view is currently selected. When the user operates the arrow key “↓”, the field for inputting the subject range from the field for inputting the angle of view is covered with diagonal lines. That is, the subject range is selected from the angle of view. In this way, by operating the cross key, the user can select an angle of view or a subject range to be alternatively input.

When the user operates the SET key while the angle of view is selected, the state is switched to a state in which the angle of view can be input, and a desired number (here, the angle of view) can be input.
As a method for inputting this number, when the arrow key “↓” is operated, the numbers “1, 2, 3,..., 9, 0” are sequentially switched. On the contrary, the numbers are switched to “0, 9, 8,..., 2, 1”.

Further, when the “→” of the cross key is operated, the space to be input is moved to the right, and conversely, if the “←” of the cross key is operated, the space to be input is moved to the left. Thus, the user can input a desired number (here, the angle of view) by operating the cross key. Here, it is assumed that the user inputs “15”. Further, when the subject range is input instead of the angle of view, the input can be performed in the same manner as the input of the angle of view described above.
When the user inputs a number (here, the angle of view) and operates the execution key, the DSP / CPU 3 sets the input angle of view as the angle of view θ.

Returning to the flowchart of FIG. 4, when setting of the view angle θ or the subject range X is performed in step S5, the process proceeds to step S6, and the focal length f corresponding to the set view angle θ or subject range X is calculated. The focal length f is calculated according to Equation 1 when the angle of view θ is set, and according to Equation 2 when the subject range X is set. In order to calculate the focal length f from the subject range X, the subject distance is required, but the subject distance is determined by the position of the focus lens 14. Note that the subject distance may be obtained by a phase difference method or an active method using infrared rays, or a distance input by a user's eye measurement may be used.
Next, the process proceeds to step S7, the zoom lens 15 is moved to a position corresponding to the calculated focal length f, and the process returns to step S2.

If the shutter button is pressed halfway in step S2, the process proceeds to step S9, where AE and AF processes are performed, and the through image display of the subject is resumed in step S10.
Next, the process proceeds to step S 11, where the angle of view θ is calculated from the focal length f and imaging range X ′, and the subject range X is calculated from the focal length f, imaging range X ′, and subject distance, and stored in the DRAM 6.
The angle of view θ is calculated according to Equation 3, and the subject range X is calculated according to Equation 4.
Here, the calculated angle of view θ and subject range X are 15 ° and 143 m, respectively. The subject distance can be obtained from the position of the focus lens 14 set by the AF process in step S9. Further, the subject distance may be obtained by a phase difference method or an active method using infrared rays, or a distance input by a user by eye measurement may be used. In addition, when the angle of view or the subject range is input by the user by automatic zooming, the input angle of view or the subject range may be stored in the DRAM 6 without calculating the angle of view θ or the subject range X. .

Next, the process proceeds to step S12, and the imaging angle X'i corresponding to the field angle θi for each scale unit and the subject range Xi for each scale unit is calculated and stored in the DRAM 6.
The angle of view θi for each scale unit means, for example, an angle of view with a scale of θi = 5 °, 10 °, etc. when the angle of view θ of the captured image is 15 °, and the angle of view for each scale unit. The imaging position X′i corresponding to θi refers to a position on the CCD 2 corresponding to an angle of view of 5 °, 10 ° or the like of the captured image.
The subject range Xi for each scale unit is a range in which the subject range of the captured image is 150 m, and when the center of the image is 0, the scale is 25 m or 50 m away from the center. The imaging position X′i corresponding to the subject Xi for each graduation unit refers to a range on the CCD corresponding to a range 25 m or 50 m away from the center of the captured image.

Next, the process proceeds to step S13, where the calculated field angle θ, subject range X, field angle θi for each scale unit, and subject range Xi for each scale unit are displayed on the image display portion 10 together with the through image of the subject.
FIG. 6G shows the state at that time. In the image display frame 20 in FIG. 6G, an image when a landscape as shown in FIG. 5F is captured is displayed. FIG. 5F includes a mountain 30, a river 40, and a bridge 50.

  It can be seen that “X = 143” is displayed on the upper right side in the image display unit 10 of FIG. 6G and “Y = 107” is displayed on the upper left side. X represents the calculated distance of the subject range X, and Y represents the vertical distance of the subject range. Y can be obtained from X by the ratio of X ′ and Y ′ of the CCD 2. Further, “L = 543 m” is displayed on the upper right side in the image display frame 20, and this represents the distance to the subject (subject distance). Although “θ = 15 °” is displayed at the upper center of the image display unit 10, this represents the angle of view of the captured image, that is, the calculated angle of view θ.

Further, scale angles of 5 ° and 10 ° are displayed on the diagonal line from the upper right to the lower left of the image, and a horizontally long rectangle is displayed immediately below each angle. This angle indicates the angle of view of the image in the horizontally long rectangle immediately below the angle. That is, the angle of view of the image in the horizontally long rectangle immediately below 10 ° is 10 °. The position in the horizontally long rectangular image is determined by the imaging position X′i corresponding to the angle of view θi calculated in step S12.
A dotted line frame 60 represents a horizontal distance scale of the subject range, and a dotted line frame 70 represents a vertical distance scale of the subject range.
The position of the horizontal scale of the subject range is determined by the imaging position X′i corresponding to the subject range Xi calculated in step S12, and the vertical scale position of the subject range is the ratio of X ′ and Y ′ of the CCD 2. Can be obtained from X′i.

FIG. 6 (h) is an image when a landscape as shown in FIG. 5 (f) is captured at an angle of view of 10 °. As is apparent from FIG. 6 (h), the image in the horizontally long rectangle immediately below 10 ° in FIG. 6 (g) is enlarged and displayed in the image display frame 20 in FIG. 6 (h). I understand. By looking at this angle of view scale, the user can recognize how many times the angle of view θ is set to capture a desired image and an appropriate image.
Also, when looking at the horizontal scale (dotted line frame 60) and vertical scale (dotted line frame 70) of the subject range in Fig. (G), the horizontal length of the bridge is about 130m and the vertical height is about 13m from the water surface. It can be seen that it is. Thereby, the user can easily recognize how large the captured subject is.

  Further, 80 part of the image display unit 10 represents the zoom amount and the focal length amount, and “5 ×” is displayed on the upper part of the 80 part and “1 ×” is displayed on the lower part. I can see that “5 ×” and “1 ×” represent “5 × zoom” and “1 × zoom”, respectively. When the black part of the 80 part reaches the position of “5 ×”, the subject is imaged at 5 × zoom, and when the black part of the 80 part is not displayed at all, it is not zoomed. This means that the subject is imaged.

Further, numbers such as “6”, “12”, and “18” are displayed beside the 80th portion, and this indicates a focal length. If the blackened portion reaches the position of “30”, it indicates that the focal length is 30 mm, and if the blackened portion is not displayed, it indicates that the focal length is 6 mm.
As shown in FIG. 6G, it can be seen that 80 parts are black between “5 ×” and “1 ×”, so that the subject is imaged with about 3 × zoom and a focal length of about 18 mm.
In FIG. 6 (h), the 80 portion is black up to the position of “5 ×”, so that it can be seen that the subject is imaged with 5 × zoom and a focal length of 30 mm.

In step S13, when the angle of view θ, the subject range X, the angle of view θi, and the subject range Xi are displayed on the image display unit 10 together with the through image of the subject, the process proceeds to step S14 to determine whether or not the shutter button has been fully pressed. Do. If it is fully pressed, the process proceeds to step S16. If it is not fully pressed, the process proceeds to step S15.
In step S15, it is determined whether the shutter button is half-pressed continuously. If the shutter button is continuously pressed halfway, the process returns to step S14. If the shutter button is not pressed halfway, that is, if the half-press is released, the AE / AF process in step S9 is performed. The shutter speed and the like set in are canceled, and the process returns to step S2. Although the user has set the angle of view θ, etc. by automatic zooming, the image displayed by the actual through image display may be different from the user's image, the scale of the angle of view displayed along with the through image display, the subject range This is because the user may set the angle of view by automatic zooming after looking at the scale.

  If it is determined in step S14 that the shutter button has been pressed, the process proceeds to step S16 to perform still image shooting processing. Here, even line pixel signals and odd line pixel signals in one screen are sequentially output to the CCD 2 at a relatively long output shooting timing, and data (image data) for all pixels is output to the buffer memory (DRAM 6). The captured image data is recorded on the memory card 12 together with the photographing conditions (including the focal length f).

As described above, in the first embodiment, since the zoom can be automatically performed so that the angle of view θ or the subject range input by the user can be obtained, a subject having the same angle of view and size can be selected any number of times. You can shoot.
Also, you can easily shoot an image with the desired angle of view and subject range, so if you look at the captured image later, the subject may be too small, too large, or part of the subject may be missing. Can prevent and reduce failed photos.
Further, since an image having a desired angle of view can be easily obtained, it is not necessary to perform trimming later. In addition, since shooting can be performed many times with the same angle of view, it is convenient and easy to combine even when panoramic combining is performed.

Further, since the field angle θ of the image, the subject range X, the field angle θi for each scale unit, and the subject range Xi for each scale unit are displayed together with the through image of the subject, the user can recognize the field angle of the image and the subject range. Can do.
Further, by looking at the scales of the angle of view and the subject range, it is possible to easily determine how much the angle of view and the subject range can be obtained.
Furthermore, the size and length of the subject can be easily recognized by looking at the scale of the subject range.

In the through image display after performing the AE / AF processing, the angle of view θ, the subject range X, the angle of view θi for each scale unit, and the subject range Xi for each scale unit are calculated and displayed on the image display unit 10. However, the angle of view θ, the subject range X, and the like may be displayed on the image display unit 10 even when displaying a through image before AE / AF processing. At this time, if the zoom operation is performed, the focal length is increased or decreased, and the scale display of the angle of view is updated in real time accordingly. FIG. 7 shows the state at that time. FIG. 7 (i) shows a state in which the zoom is hardly performed, and a scale of an angle of view from 10 ° to 40 ° is displayed. Then, zooming is performed by operating the manual zoom button. FIG. 7 (j) shows a state when zooming of about 2 times is performed, and a scale of an angle of view up to 20 ° is displayed. FIG. (K) shows a state when zooming is performed up to about 4 times, and a scale of an angle of view up to 10 ° is displayed.
In this way, when the manual zoom button is operated, the scale of the angle of view is updated in real time, so not only the angle of view information but also the perspective direction of the zoom operation can be intuitively understood from the movement of the scale. A dynamic finder display with a sense of perspective can be realized.
When the zoom operation is performed, the scale display of the subject range may be updated in real time.

Further, only one of the angle of view or the subject range may be displayed on the image display unit 10. Also, other shooting conditions (aperture etc.) may be displayed.
FIG. 8 shows an image displayed as a through image, and shooting conditions such as an angle of view, an aperture, and a shutter speed are displayed. A dotted line frame 90 in the image display unit 10 is an aperture scale, and a dotted line frame 100 is a shutter speed scale. The thickened portion of the scale in each dotted line frame represents the aperture and shutter speed values set by the AE process. In addition, “14EV” is displayed on the upper right side, and this represents the exposure amount set by the AE process. Reference numeral 80 represents a zoom amount and a focal length amount as described above.

In addition, the user inputs the angle of view θ or the subject range X by operating the key input unit 9, but the preset value candidate list stored in advance is displayed, and the user sets the set value from the candidate list. It may be possible to select.
Alternatively, a desired angle of view θ and subject range X may be set by directly specifying the position, range, and angle of the subject image in the viewfinder through a cursor operation or a touch panel.

If it is determined in step S4 in FIG. 4 that there is automatic zooming, it may be determined whether normal automatic zooming, panoramic shooting, or trimming shooting is performed. Normal automatic zooming refers to zooming by setting the angle of view θ or the subject range X as described above. If it is determined that normal automatic zooming is performed, the process proceeds to step S5.
On the other hand, when it is determined that panoramic shooting or trimming shooting is performed, the following operation is performed.
If it is determined that the panorama shooting is performed, the process proceeds to step S31 in FIG. 9L, and θn is set as the full-field angle for panorama shooting. In this setting, the angle input by the user operating the key input unit 9 is set as the angle of view θn. Here, it is assumed that 180 ° is set.

Next, in step S32, a predetermined division number N is set. The predetermined number of divisions N means to divide the shooting of the image with the entire view angle θn into N times. That is, when N is 3, the total angle of view of the image taken by taking the image three times is θn. Also in this setting, a number input by the user's operation of the key input unit 9 is set as the predetermined division number N. Here, it is assumed that 5 is set.
Next, the process proceeds to step S33, and an angle of view θf that becomes a margin is set. The margin angle of view θf refers to the angle of view of a portion where adjacent images overlap. In this setting as well, the angle input by the user's operation of the key input unit 9 is set as the glue view angle θf. The margin angle of view θf may be a predetermined angle without input by the user. Here, it is assumed that 5 ° is set.
Next, the process proceeds to step 34, and an angle of view θ (necessary angle of view θ) of an image necessary for one shooting is calculated from θn, N, and θf according to Equation 7 or Equation 8 (shooting angle of view calculation means).

The required field angle θ, the all-week field angle θn, and the marginal field angle θf calculated according to Equation 7 are as shown in FIG. In other words, if the entire circumference θn = 180 ° is simply divided into five, the angle of view of one image becomes 36 °, but it is more beautiful to provide a portion overlapping with the adjacent image (gluing angle of view). Panorama images without failure can be taken. Therefore, by using Equation 7, it is possible to calculate the angle of view θ of one image including the margin angle of view θf. Here, the angle of view θ of one shot image is 40 °.
Further, when the angle of view θ is calculated in accordance with Expression 8, the angle of view θ, the entire view angle of view θn, and the marginal view angle of view θf are as shown in FIG. 9 (n). In this case, unlike FIG. 9 (m), it can be seen that there is a margin angle of view on both sides for all images. In Formula 8, the angle of view θ of one shot image is 42 °. When the image θ is calculated, the process proceeds to Step 35, where the calculated required angle of view θ is set as the shooting angle of view θ. Proceed to S6.
Thereby, even when panoramic composition is performed later, it is convenient and easy. Further, a panoramic image having a desired angle of view can be taken by panoramic synthesis.

If it is determined that the shooting is trimming, the process proceeds to step S41 in FIG. 10 (o) to set a desired angle of view θx or θy. In this setting, an angle input by the user operating the key input unit 9 is set as an angle of view θx or θy. θx is based on the horizontal angle of view of the image, and θy is based on the vertical angle of view of the image.
Next, the process proceeds to step S42, where the margin angle of view θf is set. In this setting as well, the angle input by the user operating the key input unit 9 is set as the glue angle of view θf. The margin angle of view θf may be a predetermined angle without input by the user.
Next, in step S43, the required angle of view θ is calculated from the angle of view θx or the angles of view θy and θf according to Equation 9 (shooting angle of view calculation means).

The required angle of view θ, the angle of view θx or θy, and the marginal angle of view θf calculated according to Equation 9 are as shown in FIG. That is, when the field angle θx is set, the entire field angle including the left and right field angles θf is calculated, and when the field angle θy is set, the upper and lower field angles θf are included. The entire angle of view is calculated.
When the image θ is calculated, the process proceeds to step 44, where the calculated required field angle θ is set as the shooting field angle θ, and the process proceeds to step S6 in FIG.
This is convenient and simple even when the captured image is trimmed later.

[Second Embodiment]
Next, a second embodiment will be described.
In the second embodiment, bracketing shooting is performed at an angle of view set by the user.

D. Configuration of Digital Camera 1 The second embodiment also implements the photographing apparatus of the present invention by using a digital camera 1 having a configuration similar to that shown in FIG.
The digital camera 1 according to the second embodiment is slightly different from the first embodiment in configuration functions in the following points.
When the shooting mode is set by the user's operation of the key input unit 9, it is determined whether or not the angle of view bracketing shooting mode is set. If it is determined that the angle-of-view bracketing shooting mode is selected, the DSP / CPU 3 causes the image display unit 10 to display fields for inputting the angle-of-view bracketing shooting conditions for the angle of view θ, the correction interval, the correction order, and the number of shots. The angle of view θ, the correction interval, the correction order, and the number of shots input by the user are set as shooting conditions for bracketing shooting.

Here, the correction interval means an interval (Δθ) at which bracketing is performed in angle-of-view bracketing shooting. For example, when the set correction interval Δθ is 2 °, the subject is photographed while changing the angle of view by 2 °. Further, the angle of view θ refers to a standard angle of view taken by bracketing shooting.
Further, the correction order is a photographing order of angles of view for photographing a subject. In the case of the ascending direction (+ direction), for example, θ-2Δθ, θ-Δθ, θ, θ + Δθ, θ + 2Δθ, and the like, the angle of view increases by Δθ, and in the descending direction (− direction), For example, θ + 2Δθ, θ + Δθ, θ, θ−Δθ, θ−2Δθ means that the angle of view decreases by Δθ, and the ascending direction reverses the imaging order of the angle of view. In the case of the 0 + − direction, for example, the field angle is increased by Δθ from the standard field angle, such as 0, θ + Δθ, θ + 2Δθ, θ−Δθ, and θ−2Δθ, and then the field angle is changed from the standard field angle θ. It means decreasing by Δθ.
The number of shots refers to the number of times shot by bracketing shooting. It should be noted that an odd number of sheets is more likely to correspond to the above-described shooting order setting.

Then, the DSP / CPU 3 calculates the focal length f so that the set angle of view θ is obtained, and moves the zoom lens 15 to a position corresponding to the calculated focal length f.
If the correction interval, correction order, and number of shots are not entered, a predetermined correction interval is set. If the angle of view θ is not entered, the zoom is not performed. The zoom lens 15 is moved to the position of the focal length f that forms a corner.

Then, the DSP / CPU 3 starts imaging by the CCD 2 and displays a through image of the subject on the image display portion 10. At this time, as described in the first embodiment, the angle of view θ of the captured image, the subject range X, the angle of view θi of each unit scale, and the subject range Xi of each unit scale are displayed together with the through image of the subject. 10 may be displayed.
Then, it is determined whether or not the shutter button is half-pressed. If the shutter button is half-pressed, AE / AF processing is performed. If the shutter button is not half-pressed, it is determined whether or not a zoom operation has been performed.

If it is determined that there is a zoom operation, zoom processing is performed. At this time, as described in the first embodiment, when the automatic zoom is performed, the zoom lens 15 is moved so that the set angle of view θ or the subject range X is set, and the manual zoom is performed. In this case, normal zoom processing may be performed. At this time, when the zoom process is performed, the view angle θ set as the shooting condition for the view angle bracketing shooting becomes the view angle θ changed by the zoom process.
When the zoom process is performed, it is determined whether or not the shutter button is half-pressed. If the shutter button is not half-pressed, the above operation is repeated, and if the shutter button is half-pressed, the AE / AF process is performed.

When performing the AE / AF processing, the DSP / CPU 3 starts imaging by the CCD 2 and displays a through image of the subject on the image display unit 10. This is because the through image display is temporarily interrupted during the AF process. Also at this time, as described in the first embodiment, the angle of view θ of the image, the subject range X, the angle of view θi of each unit scale, the subject range Xi of each unit scale, the shooting conditions (aperture, shutter speed, etc.) Etc.) may be displayed on the image display unit 10.
Then, the DSP / CPU 3 determines whether or not the shutter button has been fully pressed. If the shutter button has been fully pressed, the shooting conditions (correction interval, correction order, number of corrections, angle of view θ) of the bracketing shooting described above. (However, if the angle of view is changed by the zoom process, the angle of view θ is changed)).
Then, the DSP / CPU 3 records the shooting conditions (including the angle of view, the focal length, etc.) on the memory card 12 (recording unit) together with the image data obtained by the shooting process of bracketing shooting (recording control unit).

  When the DSP / CPU 3 determines that the shutter button is not fully pressed, the DSP / CPU 3 determines whether the shutter button is continuously pressed halfway. If the shutter button is continuously pressed, the shutter button is fully pressed. The above operation is repeated. On the other hand, if it is determined that the half-press is not continued, the shutter speed set by the AE / AF processing is canceled and the through image of the subject is displayed.

E. Operation of Digital Camera 1 The operation of the digital camera 1 in the second embodiment will be described with reference to the flowchart of FIG.
When the view angle bracketing shooting mode is set by the user's operation of the key input unit 9, it is determined in step S51 whether or not the view angle bracketing shooting mode is set. If it is determined that the angle-of-view bracketing shooting mode is selected, the process proceeds to step S52, and the angle of view θ, the correction interval Δθ, the shooting order, and the number of shots input by the user are set as shooting conditions for bracketing shooting.
On the other hand, if it is determined that the angle-of-view bracketing shooting mode is not set, the process stays at step S51 until the bracketing shooting mode is set.

Here, input of the user's angle of view θ, correction interval Δθ, and the like will be described.
When the bracketing shooting mode is set by the user's operation of the key input unit 9, as shown in FIG. 12 (q), “view angle θ, correction interval Δθ, shooting order, and number of shots are input. Please enter "and a field for entering the angle of view, correction interval, shooting order, and number of shots is displayed below. It can also be seen that the angle of view is selected (the portion covered by the shaded area). This selection can freely select a field that the user wants to input by operating the cross key.

Then, the user can select a field to be input and operate the SET key to input an angle or the like. When the user operates the SET key, the state returns to a state in which the user can select the field to be input. The input method of the angle and the like is as described in the first embodiment, but the shooting order is different.
When the shooting order is selected by the operation of the cross key and the SET key is operated, the display is switched as shown in FIG. That is, "+", "-", "0 +-", and "0- +" are displayed in the shooting order input field. This “+” means that the angle of view to be bracketed is in the ascending direction, that is, bracketing shooting is performed in the order of “..., Θ−2Δθ, θ−Δθ, θ, θ + Δθ, θ + 2Δθ,. “-” Means bracketing photographing in the descending direction, that is, “..., Θ + 2Δθ, θ + Δθ, θ, θ−Δθ, θ−2Δθ,.

“0 + −” means shooting in the order of “θ, θ + Δθ, θ + 2Δθ,..., Θ−Δθ, θ−2Δθ,...”, “0− +” means “θ, θ -Δθ, θ-2Δθ,..., Θ + Δθ, θ + 2Δθ,. The portion covered by the shaded area means the currently selected shooting order. When the user operates the cross key “↓”, the portion covered by the shaded area is changed from “+” to “−”. "," 0 +-", and" 0- + ". In this way, the user can select the desired shooting order by operating the cross key.
When the user operates the SET key, the screen returns to a state where a field to be input such as an angle and the number of shots can be selected.
Then, when the user inputs the angle of view θ and the correction interval and operates the execution key, the inputted shooting conditions such as the angle of view and the number of shots are set as shooting conditions for bracketing shooting. Here, it is assumed that the angle of view θ is set to 12 °, the correction interval Δθ is set to 2 °, the shooting order is “−”, and the number of shots is set to three. Note that predetermined shooting conditions are automatically set as shooting conditions (correction interval, number of shots, shooting order) not input by the user. When the angle of view θ is not input, the angle of view is set to be the angle of view when the zoom is not performed.

Returning to the description of the flowchart of FIG. 11, when the angle of view θ, the correction interval Δθ, the shooting order, the number of shots, and the like are set in step S52, the focal length f is calculated from the angle of view θ set in step S53. This calculation can be obtained by Equation 1.
Next, in step S54, the zoom lens 15 is moved so that the calculated focal length f is obtained.
Next, the process proceeds to step S55, and a through image of the subject is displayed on the image display unit 10. At this time, as described in the first embodiment, the image angle θ, the subject range X, the angle of view θi for each scale unit, and the subject range Xi for each scale unit are displayed on the image display unit 10. May be.

Next, the process proceeds to step S56, and it is determined whether or not the shutter button has been half-pressed. If the shutter button is half-pressed, the process proceeds to step S59. If the shutter button is not half-pressed, the process proceeds to step S57, and it is determined whether or not a zoom operation has been performed.
If it is determined that the zoom operation has not been performed, the process returns to step S56. If it is determined that the zoom operation has been performed, the process proceeds to step S58 to perform zoom processing and then returns to step S56. As described in the first embodiment, this zoom processing is automatic zooming. In the case of automatic zooming, the zoom lens 15 is moved so that the angle of view θ or the subject range X set by the user is reached, and manual zooming is performed. In this case, normal zoom processing may be performed. At this time, when zoom processing is performed, the view angle θ set as the shooting condition for the view angle bracketing shooting in step S52 is changed to the view angle θ set by the zoom processing. Here, it is assumed that zoom processing is not performed.

If it is determined in step S56 that the shutter button has been half-pressed, the process advances to step S59 to perform AE / AF processing on the subject.
Next, in step S60, imaging by the CCD 2 is started and a through image of the subject is displayed on the image display unit 10. This is because the temporary through image display is interrupted by the AF process. At this time, as described in the first embodiment, the angle of view θ of the captured image, the subject range X, the angle of view θi for each graduation unit, the subject range Xi for each graduation unit, other shooting conditions, etc. (shutter speed) , Aperture, etc.) may be displayed on the image display unit 10 together with the through image of the subject.

  In step S61, it is determined whether the shutter button has been fully pressed. If it has been fully pressed, the process proceeds to step S63. If it has not been fully pressed, the process proceeds to step S62, and it is determined whether or not the shutter button has been pressed halfway. If the half-press is continued, the process returns to step S61. If the half-press is released, the shutter speed set by the AE / AF process in step S59 is canceled, and the process returns to step S56. This is because the user may want to set the angle of view again.

If it is determined in step S61 that the shutter button has been fully pressed, a shooting process is performed in accordance with the set bracketing shooting conditions in step S63.
The shooting conditions for bracketing shooting here are: the angle of view θ is 12 °, the correction interval Δθ is 2 °, the shooting order is “−”, and the number of shots is three. The angle of view “θ + Δθ” of the second image is 14 °, the angle of view “θ” of the second image is 12 °, and the angle of view of the third image is “θ−Δθ”. 10 °.

FIG. 13 shows a time chart of an image taken by bracketing shooting. The angle of view of the first image is 14 °, the angle of view of the second image is 12 °, and the third image. It can be seen that the angle of view is 10 °.
In step S63, when shooting processing for bracketing shooting is performed, the process proceeds to step S64, and shooting conditions (including the angle of view θ and the focal length f) are recorded in the memory card 12 together with the shot image data.

As described above, in the second embodiment, since the user can set the angle of view, bracketing shooting of the angle of view can be performed from the set angle of view. A desired image can be obtained.
In addition, since the user can set the correction interval Δθ, an image having an angle of view desired by the user can be obtained. Further, by setting a desired angle of view to some extent and adjusting the correction interval Δθ, a more appropriate desired image can be obtained by bracketing photography.

  In addition, since the number of shots can be set, it is possible to obtain a more appropriate and desired image by setting an appropriate number according to the situation at the spot. That is, when it is considered that the image desired by the user can be almost obtained by the angle of view θ of the image set by the user, the number of shots can be reduced, and the image desired by the user is obtained by the angle of view θ of the image set by the user. When it is impossible to do so, an appropriate image desired by the user can be obtained by increasing the number of shots.

In the second embodiment, the subject is shot by angle-of-view bracketing shooting, but the subject may be shot by subject range bracketing shooting. In this case, the correction interval is not Δθ but Δm (the interval of the bracketing distance).
In addition to angle-of-view bracketing shooting and subject range bracketing shooting, bracketing shooting may be performed by combining other shooting conditions (exposure, white balance, etc.).

FIG. 14 shows an image taken by angle-of-view / exposure bracketing photography.
In FIG. 14, the angle of view for bracketing is three (14 °, 12 °, 10 °), and the angle of exposure for bracketing by exposure is three (-3EV, ± 0EV, + 3EV). The total number of times of shooting by bracketing shooting is 3 × 3.

As can be seen from FIG. 14, the first to third images (the upper three images in FIG. 14) have an angle of view of θ = 14 °, and the exposure is “10EV-3EV”. It can be seen that the second sheet is “10 EV ± 0 EV” and the third sheet is “exposure is 10 EV + 3 EV”.
The fourth through sixth images (three in the middle of FIG. 14) have an angle of view of θ = 12 °, and the exposure is the same as the first through third exposures. That is, the fourth sheet is “10EV-3EV”, the fifth sheet is “10EV ± 0EV”, and the sixth sheet is “exposure is 10EV + 3EV”.
The seventh to ninth images (the lower three in FIG. 14) have an angle of view of θ = 10 °, and the exposure is the first to third, the fourth to sixth, and the exposure. It is the same.
Here, 10 EV means exposure set by AE processing, that is, standard exposure.

There are various shooting orders for bracketing in which the angle of view and exposure or the subject range and exposure are combined, but in the case of angle of view bracketing and subject range bracketing, the zoom lens 15 moves in small increments, so driving the lens Time and power consumption are wasted. Accordingly, as described above, the angle of view or the subject range is set to the first angle of view by shooting with the angle of view or the subject range bracketing, and the focus lens 15 is not moved as in exposure bracketing and WB (white balance) bracketing. Bracketing shooting is possible. Then, after moving the angle of view or the subject range by the correction interval and again performing exposure bracketing photography or the like, the zoom lens 15 is moved by the correction interval, and the exposure lens is moved. Keting and WB bracketing are performed. That is, in multi-bracketing shooting, for those that cannot be bracketed without moving the lens, every time the lens is moved, bracketing shooting that can be bracketed without moving the lens is performed.
As a result, it is possible to perform multi bracketing shooting with a short shooting time and low power consumption. In addition, it is possible to perform multi-bracketing shooting that is unlikely to cause camera shake and image quality degradation.

Also, in white balance, sharpness, contrast, filter, color correction bracketing, etc. that can combine multiple images by image signal processing and image correction processing with only one shooting, other AF bracketing and exposure bracketing After finishing bracketing shooting that requires multiple shots such as keting, an image equivalent to bracketing shooting is created by correcting and combining images with different conditions by image signal processing, image correction processing, software processing, etc. You may make it do.
In addition, flash bracketing, etc., due to differences in the amount of light emitted from the flash, etc., requires charging time individually, and the required time varies individually. You may make it carry out from such a thing or the imaging | photography of a standard appropriate value first. Further, the user may arbitrarily select it.

  Even in the bracketing shooting mode, it is determined whether panoramic shooting or trimming shooting is to be performed, and after calculating the panoramic angle of view and trimming angle of view, the angle of view bracketing shooting is performed based on the calculated angle of view. May be performed.

[Third Embodiment]
Next, a third embodiment will be described.
In the third embodiment, the best shot shooting is provided, the angle of view, the focal length, and other shooting conditions are recorded in advance for each scene, and the user automatically selects the best shot scene. The angle of view, the focal length, etc. are set in

F. Configuration of Digital Camera 1 The second embodiment also implements the photographing apparatus of the present invention by using a digital camera 1 having a configuration similar to that shown in FIG.
The digital camera 1 according to the second embodiment is slightly different from the first embodiment in configuration functions in the following points.

When the user sets the best shot shooting mode by operating the key input unit 9, the DSP / CPU 3 displays a plurality of shooting scenes (shooting modes) on the image display unit 10.
Here, FIG. 15S shows a plurality of shooting scenes displayed on the image display unit 10. The image display unit 10 displays shooting scenes such as “person portrait”, “person image (2 to 3 persons)”, “illumination photograph”, and the like. It can also be seen that the person portrait field is surrounded by a thick black line. This represents that “person portrait” is currently selected.

Then, another shooting scene can be selected by the user's operation of the cross key. For example, when the user operates the arrow key “↓”, “person image (2 to 3 people)” is selected from “Portrait” and the user operates the arrow key “→”. In this case, “landscape + person (commemorative photo)” is selected from “person portrait”.
Thus, the user can select a shooting scene to be shot by operating the cross key. When the user selects a desired shooting scene and operates the execution key, the DSP / CPU 3 determines that the selected shooting scene has been selected. Here, it is assumed that the user selects “ID photo” and operates the execution key.

When the DSP / CPU 3 determines that the operation of the execution key has been performed, it reads out shooting information corresponding to the selected shooting scene from the ROM 8 (first acquisition means), and uses the read shooting information as shooting conditions. Set. At this time, the zoom lens is moved to a position where the set focal length is obtained.
FIG. 15 (t) shows an example of shooting information stored in the ROM 8.
As can be seen from FIG. 15 (t), it can be seen that shooting conditions such as aperture, shutter speed, angle of view, and focal length are recorded in the ROM 8 for each shooting scene.
Here, “ID photo” is selected as the shooting scene, so the shooting conditions to be set are “aperture” auto, “shutter speed” auto, “field angle” 6 °, “focal length” 50 mm, etc. It turns out that it becomes.
Note that when a plurality of shooting scenes are displayed on the image display unit 10, shooting scenes for bracketing shooting may be displayed. At this time, it goes without saying that the ROM 8 records shooting information corresponding to a shooting scene for bracketing shooting.

Then, the DSP / CPU 3 displays a through image of the subject on the image display unit 10 when the shooting condition is set.
The processing of the DSP / CPU 3 after the through image display is the same as in the first embodiment and the second embodiment.
That is, if the selected shooting scene is a shooting condition for bracketing shooting, the processing of the DSP / CPU 3 after displaying the through image is the same as in the second embodiment, and the selected shooting scene is a normal still image. If the shooting condition is not shooting, that is, bracketing shooting, the processing of the DSP / CPU 3 after displaying the through image is the same as that of the first embodiment.

G. Operation of Digital Camera 1 The operation of the digital camera 1 in the third embodiment will be described with reference to the flowchart of FIG.
When the best shot shooting mode is selected by the user's operation of the key input unit 9, a plurality of shooting scenes as shown in FIG. 15 (s) are displayed on the image display unit 10 in step S71.
Here, when a plurality of shooting scenes are displayed on the image display unit 10, the user selects a desired shooting scene to be shot. In this selection, the execution key is operated after the operation of the cross key. Here, it is assumed that the user selects “ID photo” with the cross key and operates the execution key.

In step S72, shooting information corresponding to the selected shooting scene is read from the ROM 8, and the read shooting information is set as a shooting condition.
FIG. 15 (t) shows shooting information for each shooting scene recorded in the ROM 8. Here, since “ID photo” is selected, photographing information corresponding to the ID photo is read from the ROM 8. That is, the read shooting information includes “aperture” as auto, “shutter speed” as auto, “field angle” as 6 °, “focal length” as 50 mm, and the like.

When the read shooting information is set as a shooting condition, the process proceeds to step S73, and the zoom lens is moved to a position corresponding to the set focal length.
Then, imaging by the CCD 2 is started and a through image of the subject is displayed on the image display unit 10. The subsequent operation is the same as in the first embodiment. That is, when the zoom lens 15 is moved to a position corresponding to the set focal length, the process proceeds to step S1 in FIG.
Even if a still image shooting scene is selected, bracketing shooting appropriate to the selected shooting scene may be performed.
For example, when a shooting scene where a person is the subject, such as a shooting portrait “person portrait”, is selected, soft focus or flesh-color bracketing shooting is performed, or when the shooting scene is indoors, WB bracketing or Flash bracketing shooting may be performed, or when the shooting scene is “landscape”, angle of field bracketing or depth of field bracketing shooting may be performed. Depending on the scene, not only bracketing shooting, but also a special continuous shooting function, pan focus, and multiple bracketing shooting combined with 3 x 3 bracketing shooting etc. You may be able to do it.

  Even when a still image shooting scene is selected, the correction interval, shooting order, and number of shots may be input by the user's operation of the key input unit 9. That is, bracketing shooting is performed based on the selected shooting scene. In this case, when the shooting information of the selected shooting scene, the input correction interval, shooting order, and the number of shots are set as shooting conditions, the zoom lens 15 is moved to a position corresponding to the set focal length. Then, the process proceeds to step S55 in FIG.

In addition, shooting information for correction intervals, shooting order, and number of shots is recorded in advance in shooting information for each shooting scene, and when shooting scenes are selected, shooting is performed by normal still image shooting or shooting by bracketing shooting. You may make it make a user select whether to do. When normal still image shooting is selected, set the shooting conditions for normal still images without setting the shooting information of the correction interval, shooting order, and number of shots as shooting conditions, and bracketing shooting is selected. In such a case, the shooting information of the correction interval, shooting order, and number of shots is set as shooting conditions.
Also, a normal still image shooting scene and a bracketing shooting scene are recorded separately, and bracketing shooting is performed when a shooting scene for bracketing shooting is selected. May be.

As described above, in the third embodiment, when a user selects a shooting scene, shooting information corresponding to the selected shooting scene is set as a shooting condition. By simply selecting the shooting scene, etc., it automatically sets the most suitable angle of view, so you can easily adjust the angle of view and zoom in to save the subject with the appropriate angle of view. Can be taken.
In addition, it is possible to avoid a failed photograph such as shooting a subject large or small.
In addition, since the user performs desired bracketing shooting for the selected shooting scene, or the user inputs the correction interval, shooting order, number of shots, and the like, the user performs the desired bracketing shooting. You can shoot.

Note that the user selects an image recorded on the memory card 12 instead of selecting the shooting scene, so that the shooting conditions such as the angle of view recorded in association with the selected image are selected. (Shooting conditions such as an angle of view when the image is shot) may be read (second acquisition unit), and the read shooting conditions may be set as shooting conditions to shoot the subject.
Further, even if the selected image is an image shot by normal still image shooting, the user can operate the key input unit 9 to perform bracketing shooting according to the present invention, or the selected image can be shot by bracketing shooting. Even for an image, the user may operate the key input unit 9 to take a still image according to the present invention.

  As a result, the photographed image (image data recorded in the memory card 12) is viewed, and the image that best matches the composition of the image to be photographed is selected, so that the composition of the selected image is exactly the same. Images can be taken. Further, it is possible to save the trouble of adjusting the angle of view and zooming operation, and it is possible to easily shoot a subject with an appropriate angle of view. Furthermore, it is possible to avoid a failed photo such as a large subject or a small subject.

Note that the imaging device in each of the above embodiments is not limited to the above embodiment, and may be a camera-equipped mobile phone, a PDA, a personal computer, or a digital video camera. Any device can be used.
Further, although the digital camera 1 having the optical zoom function has been described, a digital camera having only the digital zoom function may be used.
