Description

  The present invention relates to an imaging apparatus typified by a digital camera, and more particularly to an imaging apparatus having a plurality of optical systems having different focal lengths and a control method thereof.

  Conventionally, an imaging device such as a video camera or a digital camera is required to be thin and have a high zoom ratio. In a conventional general imaging system, an optical system is configured by combining a plurality of optical lenses in order to suppress the occurrence of aberrations in the optical system and satisfy desired optical performance. In order to reduce the size of such an optical system, it is conceivable to reduce the image size and the aperture of the optical system. However, it is difficult to reduce the image size while maintaining the resolution.

  On the other hand, a compound eye imaging device that realizes a compact optical system by dividing the optical system into a plurality of parts has been proposed. A plurality of lens units with different angles of view are prepared, and an image sensor is provided for each lens unit so that a plurality of angles of view can be photographed. Each lens unit has a smaller diameter and a shorter focal length, and an optical system. A configuration for reducing the size is known.

  However, in the compound-eye imaging device, there is a display technique that improves the convenience in shooting by displaying shooting conditions set for each lens, that is, a plurality of shooting conditions on a shooting condition display screen such as a rear liquid crystal. Not established. For example, if the user can know the shooting conditions that are at the limit of camera shake before shooting, it will be possible to shoot images that are not affected by camera shake, thereby improving the convenience of the imaging device. To do.

  Incidentally, an example in which a plurality of pieces of shooting information is displayed on the rear liquid crystal or the like is disclosed in Patent Document 1, for example. Japanese Patent Application Laid-Open No. 2004-133620 discloses determining candidate shooting conditions that are shooting conditions suitable for each main subject candidate for each main subject candidate based on subject information of the subject determined as a main subject candidate.

Japanese Patent No. 5029765

  However, in Patent Document 1, since there is no concept of display of shooting conditions corresponding to a plurality of imaging optical systems, display for each imaging optical system cannot be performed, which is inconvenient in shooting scenes with various luminances. .

  Accordingly, an object of the present invention is to display the shooting conditions set for each imaging optical system on a shooting condition display screen such as a rear liquid crystal and change the settings, thereby improving convenience in shooting. An improved imaging device is provided.

  According to the present invention, the imaging device includes an imaging unit that simultaneously captures a plurality of optical images having different focal lengths, a display unit that displays imaging conditions for imaging the plurality of optical images, and a condition for imaging by the display unit. An operation means for operating the display, and a control means for acquiring shooting conditions for taking a plurality of optical images from the imaging means and controlling the display of the acquired shooting conditions by the display means, Including a display that associates shooting conditions for capturing a plurality of optical images with different focal lengths, and the display of the shooting conditions is controlled by the control unit based on the value of the shooting conditions so that the operation unit can operate. Yes.

  According to the present invention, the imaging conditions set for each imaging optical system are displayed on a display screen such as a back liquid crystal, and the setting can be changed, thereby improving the convenience in shooting. Can be provided.

[Example 1]
Hereinafter, an imaging apparatus according to the first embodiment of the present invention will be described with reference to FIGS.

  1 is a block diagram of an imaging apparatus 100 according to the present embodiment, FIG. 2 is a perspective view of an imaging unit 110 included in the imaging apparatus 100 of the present embodiment, FIG. 3 is a front view of the imaging unit 110, and FIG. FIG. 4 is a rear view of the imaging apparatus 100. In the figure, similar constituent elements are denoted by the same reference numerals. Further, the imaging apparatus 100 may be a lens-integrated imaging apparatus as shown in FIG. 1, or a lens apparatus having an imaging optical system (imaging optical system) and a lens apparatus that is detachably mounted to mount an imaging element. You may comprise from the imaging device main body which has.

  The imaging apparatus 100 as a camera system has an imaging system, an image processing system, a recording / reproducing system, and a control system. The imaging system includes an imaging unit 110 including an imaging optical system and an imaging element described later, and the image processing system includes an image processing unit 120. The recording / reproducing system includes a memory 197 and a display unit 170, and the control system includes a CPU 135, an imaging control unit 140, a focus group voltage driver 141 that is a lens driving unit, and a focus group driving unit 142. The control system may further include a lens CPU that performs overall lens drive control and a zoom lens drive unit as lens drive means, but these are not shown.

  1, the imaging apparatus 100 includes an imaging unit 110, an A / D converter 150, an image processing unit 120, a CPU 135, an imaging control unit 140, an image recording medium 160, a display unit 170, and a distance information calculation unit 180.

  As shown in FIG. 2, the imaging unit 110 includes eight imaging optical systems 111a, 111b, 112a, 112b, 113a, 113b, 114a, and 114b, each of which forms an optical image of a subject. In addition, a plurality of imaging elements 130a to 130h are provided corresponding to each of the plurality of imaging optical systems. The imaging unit 110 shown in FIG. 1 is a sectional view including the optical axes of the imaging optical systems 111a and 114a. Each imaging optical system includes other members such as a diaphragm (not shown).

  Each imaging optical system includes a focus group unit 105F and a rear group unit 105R. The focus group unit 105F and the rear group unit 105R are integrally held by folders 110 and 116, respectively. Thus, the focus group unit 105F can be driven in the optical axis direction by the same amount integrally during focusing by the focus group driving unit 142 using an ultrasonic motor or a stepping motor as a driving source. The rear group unit 105R is fixed during focusing.

  The focus group voltage driver 141 generates a voltage for driving and controlling the focus group driving unit 142. The focus position detection unit 143 is a focus encoder that detects the position of the focus group unit 105F along the optical axis I. The focus position detection unit 143 outputs a pulse signal corresponding to the subject distance to the imaging control unit 140.

  The imaging control unit 140 controls the focus group driving unit 142, and the focus group unit 105F is driven to a position on the optical axis I corresponding to the subject distance detected by the operation of the release switch 191 of the user's imaging device 100, for example. Follow-up control is performed. Further, the imaging control unit 140 takes in the pulse signal output from the focus position detection unit 143, and drives the drive signal based on the position (target position) on the optical axis I corresponding to the subject distance, the current position information of the focus group unit 105F, and the like. Is calculated. This drive signal is output to the focus group voltage driver 141.

  The focus group voltage driver 141 is a driver unit that supplies power to the focus group drive unit 142 in accordance with an input drive signal (drive voltage). The focus group voltage driver 141 switches the drive signal, applies a voltage to the focus group drive unit 142, and drives the focus group drive unit 142.

  In the imaging unit 110, the imaging optical systems 111a and 114a constitute a compound eye, and the imaging elements 130a and 130e respectively convert an optical image formed on the imaging element surface via the imaging optical systems 111a and 114a into electrical signals ( Analog signal). The A / D conversion unit 150 converts analog signals output from the image sensors 130 a to 130 h into digital signals and supplies the digital signals to the image processing unit 120.

  The image processing unit 120 performs predetermined pixel interpolation processing, color conversion processing, and the like on each image data from the A / D converter 150, and performs predetermined calculation processing using each captured image data. The result processed by the image processing unit 120 is transmitted to the CPU 135. The image processing unit 120 includes a super-resolution processing unit 121, an image composition unit 122, a blur addition unit 123, and a subject removal unit 124.

  The super-resolution processing unit 121 performs high-resolution processing of an image using a plurality of images, which will be described later. The image composition unit 122 generates one composite image having different image characteristics from a plurality of images, and performs processing such as reducing the noise level and creating a high dynamic range image, for example. Here, the image characteristics are any one of an image dynamic range, resolution, blur amount, angle of view, and removal rate of a photographed subject.

  The blur adding unit 123 adds blur to an image based on distance information obtained by a distance information acquisition method described later. For example, the subject removing unit 124 obtains an image from which the background other than the main subject that is designated as unnecessary by the photographer is removed based on the distance information.

  The CPU 135 is a central processing unit that performs various controls of the entire imaging apparatus 100, and controls the imaging control unit 140 based on the supplied data.

  Further, the CPU 135 receives information of the release switch 191 and detects that the release switch 191 is half-pressed or fully pressed. Thereby, driving of the image sensor 130, operation of the image processing unit 120, compression processing of the memory 197, and the like are controlled. Further, information display on a liquid crystal monitor or the like is controlled by a display unit 170 described later.

  In addition to the control of the movement amount of the focus group unit 105F, the imaging control unit 140 is not shown in accordance with the numerical values of the imaging conditions such as the aperture value and shutter speed of each imaging optical system input from the CPU 135. Necessary images are acquired by controlling the diaphragm and the image sensor. Each focus group satisfies the optical conditional expression for making the same amount of focusing movement in a plurality of imaging optical systems having different focal lengths, but differs from the gist of the present invention. Omitted. Therefore, by photographing at the position of the focus group unit 105F controlled by the imaging control unit 140, a plurality of focused images having the same field angle as different subject space ranges (field angles) are acquired by one control.

  The image recording medium 160 stores a plurality of still images and moving images, and also stores a file header when configuring an image file.

  The display unit 170 is attached to the back surface of the imaging device 100, and the user can directly observe the display of the image displayed on the display unit 170, the shooting condition setting state of the imaging device 100, or an error. Yes.

  If the display unit 170 is composed of an organic EL spatial modulation element, a liquid crystal spatial modulation element, a spatial modulation element using fine particle electrophoresis, or the like, power consumption can be reduced and the display unit 170 can be made thin. . Thereby, power saving and size reduction of the imaging device 100 can be achieved. Moreover, it is good also as a structure which can change the setting of the imaging condition of the imaging device 100 by being comprised so that the surface of the display part 170 can be directly operated (for example, touch panel) so that it may mention later.

  The distance information calculation unit 180 includes a reference image selection unit 181, a corresponding point extraction unit 182, and a parallax amount calculation unit 183. The reference image selection unit 181 selects a reference image from a plurality of parallax images formed by each imaging optical system. The corresponding point extraction unit 182 extracts corresponding pixels in the parallax image. The parallax amount calculation unit 183 calculates the parallax amount of all the extracted corresponding points, and the distance information calculation unit 180 calculates subject distance information in the image from the calculated parallax amount.

  As described above, the release switch 191 is a switch that detects a half-press operation (SW1 ON) and a full-press operation (SW2 ON) of a release button (not shown). SW1 ON is detected to start a series of shooting preparation operations (photometry operation, focus adjustment operation, etc.), SW2 ON is detected, and shooting operation (recording medium for image data read from the image sensor 130) is detected. This is a switch for starting recording.

  A selection switch (operation member) 192 that can be operated in an arbitrary direction selects an item of a well-known shooting menu (not shown), or selects an imaging optical system for a user to determine shooting conditions, as will be described later. This switch is used when Reference numeral 193 denotes a determination switch, which is used when a known shooting menu (not shown) is determined or when a user determines shooting conditions as will be described later.

  Reference numeral 195 denotes a main switch for activating the imaging apparatus 100. Reference numeral 196 denotes a mode switch for setting a shooting mode of the image pickup apparatus 100, and a “shooting condition individual setting mode” to be described later can be set.

  A memory 197 includes a processing circuit necessary for recording in addition to an actual storage unit. The memory means generates and stores an image to be output to the display unit 170 while outputting to the recording unit.

  The memory 197 is also used as a work area when compressing images, moving images, sounds, and the like using a predetermined method.

  Next, the imaging unit 110 will be described in more detail.

  As shown in FIG. 2, the imaging unit 110 includes an imaging element unit 200 in which a plurality of imaging elements 130 a to 130 f are integrally held. The imaging element 130a corresponds to the imaging optical system 111a, the imaging element 130b corresponds to the imaging optical system 112a, the imaging element 130c corresponds to the imaging optical system 111b, and the imaging element 130d corresponds to the imaging optical system 112b. To do. The imaging element 130e corresponds to the imaging optical system 114a, the imaging element 130f corresponds to the imaging optical system 113a, the imaging element 130g corresponds to the imaging optical system 114b, and the imaging element 130h corresponds to the imaging optical system 113b. Corresponding to

  The image sensors 130a to 130h are specifically CMOS process compatible sensors (hereinafter abbreviated as CMOS sensors) which are one of the amplification type solid-state image sensors. The CMOS sensor is characterized in that the MOS transistor in the area sensor section and peripheral circuits such as the imaging device drive circuit, AD converter circuit, and image processing circuit can be formed in the same process. Therefore, the number of masks and process steps are compared with those of the CCD. Has the advantage that it can be greatly reduced.

  As shown in FIG. 3, the optical axes of the eight imaging optical systems 111a, 112a, 113a, 114a, 111b, 112b, 113b, and 114b are arranged so as to be substantially parallel.

  Further, the two imaging optical systems a and b having the same reference numerals have the same focal length, and in this embodiment, four sets of imaging optical systems having different focal lengths are provided.

The imaging optical systems 111a and 111b are a pair of wide-angle imaging optical systems having the shortest focal length among the eight imaging optical systems. The imaging optical systems 112a and 112b are a pair of imaging optical systems having a longer focal length than the imaging optical systems 111a and 111b. The imaging optical systems 113a and 113b are a pair of imaging optical systems having a longer focal length than the imaging optical systems 112a and 112b.
The imaging optical systems 114a and 114b are a pair of imaging optical systems having a longer focal length than the imaging optical systems 113a and 113b.

  In FIG. 3, the focal length of the imaging optical systems 111a and 111b is 35 mm, the focal length of the imaging optical systems 112a and 112a is 75 mm, the focal length of the imaging optical systems 113a and 113b is 150 mm, and the imaging optical system The focal lengths of 114a and 114b are set to 300 mm.

  FIG. 5 shows examples of captured images 511a, 512a, 513a, and 514a corresponding to the imaging optical systems 111a, 112a, 113a, and 114a. As shown in the figure, the captured image 511a corresponding to the imaging optical system 111a is the widest subject space, and the captured images 512a, 513a, and 514a corresponding to the imaging optical systems 112a, 113a, and 114a have a focal length. Accordingly, the subject space to be imaged is narrowed.

  Next, a display configuration on the display unit 170 according to the present embodiment will be described.

  FIG. 6 is a diagram illustrating an example of a display screen including display of a subject image displayed on the display unit 170 during so-called live view shooting in the imaging apparatus 100 according to the present embodiment.

  In the figure, the display unit 170 includes a first display area 670a and a second display area 670b, and the first display area 670a includes a subject image display area 610 and an imaging condition determination area 620. The shooting condition determination area 620 displays shooting conditions of imaging optical systems 111a to 114b, which will be described later, and an image (denoted as a result indicator) that suggests the influence of shooting conditions on a shot image obtained as a result of shooting under the shooting conditions. To do. The second display area 670b displays shooting information such as shooting conditions (shutter speed, aperture value, ISO sensitivity, etc.) and battery remaining amount display. As shown in FIG. 6, the subject image 610 and the shooting condition determination area 620 are displayed in the display area 670 a so as not to overlap, but the shooting condition determination area 620 is overlapped with the subject image 610. You may display.

  The imaging condition determination area 620 includes a focal length area 621 in which focal lengths corresponding to the imaging optical systems 111a, 112a, 113a, and 114a are displayed. In addition, an indicator 622 for setting the photographing conditions of the imaging optical systems 111a, 112a, 113a, and 114a (shutter speed in the display example of this embodiment) and the result indicator 623 described above are displayed.

  The indicator 622 is displayed as a predetermined icon that can be operated to set the value of the shooting condition according to the display position, for example, as shown in the figure, and the operation is an operation of the selection switch 192 or a touch operation (touch panel on the display unit 170). ) Etc. In addition, since the focal lengths of the imaging optical systems 111a, 112a, 113a, and 114a are set to 35 mm, 75 mm, 150 mm, and 300 mm in order, as described above, these displays are displayed as 621a, 621b, 621c, and 621d. . Furthermore, the setting value of the imaging condition to be set is displayed according to the position of the indicator 622, and the setting can be facilitated by appropriately changing and displaying the set value according to the movement by the operation. In this case, the display form of the set value is not limited to a numerical value, but is a design matter that may be appropriately determined as necessary, such as color shading.

  As described above, the imaging conditions of the imaging optical systems 111a, 112a, 113a, and 114a are displayed side by side in the order of the focal length, so that the imaging conditions accompanying the change in the focal length and the influence on the captured image can be immediately understood. Therefore, the convenience of the imaging device is improved.

  In the display example of FIG. 6, the result indicator 623 indicates a shake of the image when the subject image 610 is captured under the capturing conditions set. Therefore, since the user can confirm before shooting that the shooting result with which the influence of the shake is obtained under the shooting conditions set for each focal length is obtained, the convenience of the imaging apparatus is improved. In FIG. 6, a result indicator 623 that indicates the degree of shake of the three-stage captured image is illustrated, but the display configuration thereof will be described later.

  Next, the photographing processing operation of the image pickup apparatus according to the present embodiment including the display operation shown in FIG. 6 will be described with reference to the flowchart of FIG. The imaging apparatus according to the present embodiment has a first mode in which imaging conditions of a plurality of optical images having different focal lengths are set to be the same, and imaging conditions of a plurality of optical images having different focal lengths. There is a second mode in which imaging is performed as changeable. The display control according to the present invention is executed in the second mode.

  FIG. 7 shows a flowchart of the shooting operation of the imaging apparatus 100 according to the present embodiment. This operation is controlled by the CPU 135.

  In step (hereinafter referred to as S) 701, the CPU 135 determines whether or not the main switch 195 is ON. If the main switch 195 remains off as a result of the determination, the imaging apparatus 100 remains in the sleep state and waits for the main switch 195 to turn on. If the main switch 195 is turned on, the process proceeds to S702.

  In step S <b> 702, the CPU 135 determines whether the imaging apparatus 100 is in the “shooting condition individual setting mode” that is the second mode. As a result, when the “shooting condition individual setting mode” is set (Yes), the process proceeds to S703. If the “imaging condition individual setting mode” is not set (in the case of No), the imaging conditions of the respective imaging optical systems 111a, 112a, 113a, and 114a are set to be the same (first imaging). Mode), the process proceeds to S720. Note that the processing operation of the imaging apparatus 100 in S720 is different from the gist of the present invention, and the details thereof are omitted.

  In step S <b> 703, the CPU 135 acquires and checks shooting conditions such as an aperture value and a shutter speed currently set by the user.

  In S704, each shooting condition acquired and confirmed by the CPU 135 in S703 is displayed on the display unit 170.

  The display configuration here will be described using the display example shown in FIG. The figure shows only the photographing condition determination area 620, and the same parts as those in FIG. 6 are denoted by the same reference numerals. Further, the display of “setting value”, “focal length”, etc. shown in FIG. 6 is omitted. As shown in FIG. 8, in the photographing condition determination area 620, indicators 622 (622a to 622d) and result indicators 623 (623a, 623b, 623c) are displayed. These are displayed for each focal length display 621a of each imaging optical system 111a, 112a, 113a, 114a displayed in the focal length area 621.

  In step S <b> 705, the CPU 135 determines whether the shooting condition of the imaging apparatus 100 has been changed by the user. Specifically, the user uses the selection switch 192 to select the indicator 622 for changing the shooting condition, and then uses the determination switch 193 to determine the indicator 622 (for example, 622d) for changing the shooting condition. Next, using the selection switch 192 and the determination switch 193 again, the CPU 135 confirms whether or not the photographing condition (in the example shown in FIG. 8A) has been changed. Alternatively, as described above, the imaging condition may be changed by operating the indicator 622 by directly operating the surface of the display unit 170.

  In S <b> 705, the CPU 135 proceeds to S <b> 730 when the shooting condition is changed (Yes), and proceeds to S <b> 706 when the shooting condition is not changed (No).

  Hereinafter, in S705, the case where the indicator 622d for determining the imaging conditions of the imaging optical systems 114a and 114b is operated and the shutter speed as the imaging conditions is changed from 1/125 seconds to 1/500 seconds will be taken as an example. The subsequent photographing processing operation will be described.

  In S730, the shutter speed (Tv) changed by the user is based on the reciprocal 1 / f (= 1/300) of 300 mm, which is the focal length (f) of the imaging optical systems 114a and 114b whose imaging conditions have been changed. The CPU 135 determines whether or not it is larger.

  When the shutter speed set by the user is larger than the reciprocal of the focal length, the process proceeds to S740, and when the shutter speed set by the user is smaller than the reciprocal of the focal distance, the process proceeds to S731. Here, since the user has changed the shutter speed setting of the imaging conditions of the imaging optical systems 114a and 114b to 1/500 second, the process proceeds to S731 as a result of the determination in S730. That is, as shown in FIG. 8B, it is assumed that the setting of the shutter speed is changed to 1/500 second by the user operating the indicator 622d and setting it to the position 822e.

  When the shutter speed set by the user is smaller than the reciprocal of the focal length, the influence of camera shake on the captured image is almost eliminated. Therefore, in S731, the result indicator 623 is changed from the result indicator 623c that suggests the occurrence of the influence of camera shake to the result indicator 623a that indicates that there is almost no influence of the camera shake, and the process returns to S705. As a result, the user visually changes the shutter speed, which is a shooting condition, so that the captured image of the optical image of the subject imaged by the imaging optical systems 114a and 114b is not affected by camera shake. Therefore, the convenience of the imaging device is improved.

  In S740, the shutter speed (Tv) changed by the user is the reciprocal 1 / f (= 1/300) of 300 mm, which is the focal length (f) of the imaging optical systems 114a and 114b whose imaging conditions have been changed. The CPU 135 determines whether it is greater than twice. If the shutter speed set by the user is larger than twice the reciprocal of the focal length, the process proceeds to S750, and if the shutter speed set by the user is smaller than twice the reciprocal of the focal distance, the process proceeds to S741. Here, it is assumed that the user has changed the shutter speed setting of the imaging conditions of the imaging optical systems 114a and 114b from 1/125 seconds to 1/200 seconds, and the process proceeds to S741.

  In S741, since the shutter speed set by the user is smaller than twice the reciprocal of the focal length, the influence of camera shake is reduced compared to the case where the set value is 1/125 seconds at the same focal length. Therefore, the result indicator 623 is changed from the result indicator 623c where the influence of camera shake occurs to the result indicator 623b which suggests that the influence of camera shake is reduced, and the process returns to S705.

  As a result, when the user changes the shutter speed, which is a shooting condition, the display of the result indicator 623b is changed based on the change amount. As a result, the user can visually recognize that the influence of camera shake on the captured images imaged by the imaging optical systems 114a and 114b is changed, so that the convenience of the imaging apparatus is improved.

  S750 is a processing operation when the shutter speed set by the user is larger than twice the reciprocal of the focal length of the imaging optical systems 114a and 114b. This is a processing operation when it is determined that an influence appears. Therefore, the result indicator 623 is changed to the result indicator 623c in which the influence of camera shake occurs, and the process returns to S705.

  In S706, the CPU 135 determines whether or not the release switch 191 has been half-pressed. As a result of the determination, if the half-pressing operation has been performed (Yes), the process proceeds to S707, and if not (No), the process returns to S705.

  In S707, the distance to the subject is calculated by measuring the subject from the image information acquired by the image sensor 130 and operating the above-described parallax amount calculation unit 183. Alternatively, the photographing apparatus 100 may include a photometric means and a distance measuring means (not shown), and the photometry and distance measurement of the subject may be performed by operating the photometric means and the distance measuring means.

  In S708, the imaging control unit 140 receives the calculation result of S707 from the CPU 135, drives the focus group unit 105F by the focus group driving unit 142, and moves the focus group unit 105F to a position where the subject obtained in S707 is in focus. To do. In S709, the image focused on the subject is displayed on the display unit 170 as a preview image before photographing.

  In S710, the CPU 135 determines whether the release switch 191 has been fully depressed (whether SW2 is turned on). If No, the process returns to S705 and a series of operations are repeated. If Yes, the process proceeds to S711.

  In S711, a known shooting operation is performed. In S712, the subject image formed on the image sensor 130 is displayed on the display unit 170 as a recorded image processed by the image processing unit 120 through a known image processing technique. In S713, the image is recorded in the memory 197 or the image recording medium 160.

  In S714, the CPU 135 determines whether or not the release switch 191 is continuously pressed, that is, whether the SW2 is OFF. If the full-pressing operation of the release switch 191 is continued, that is, if SW2 is ON (Yes), the process returns to S711 and a series of photographing operations are repeated. If it is not ON (No), the process proceeds to S715.

  In S715, the CPU 135 determines whether the half-pressing operation of the release switch 191 is continued, that is, whether the SW1 is not turned off. If the half-pressing operation of the release switch 191 continues, that is, if SW1 is ON (Yes), the process returns to S707, and the sequence from S707 to S715 is repeated.

  On the other hand, if the SW1 is turned off in S715, that is, if the shooting is finished (No), the process proceeds to S716. In S716, the CPU 135 determines whether or not the main switch 195 is turned off. If NO, the process returns to S701 to perform a series of shooting operations. If YES in S716, the shooting operation is terminated.

  As described above, according to the present embodiment, the user can individually change / set the imaging conditions of the imaging optical systems 111a to 114a by operating the displayed indicators 622a to 622d. Become.

  In other words, an imaging apparatus having an imaging unit that simultaneously captures a plurality of optical images with different focal lengths, by enabling the imaging conditions set for imaging each optical image to be displayed on the imaging condition display screen. An imaging device with improved convenience can be provided.

  When the imaging conditions of the imaging optical systems 111a to 114a are changed, the display form of the result indicator 623 changes accordingly, so that the user can check the imaging result when the imaging conditions are changed before imaging. Therefore, an imaging device with further improved convenience can be provided.

  Note that the shooting conditions to be displayed are not limited to the shutter speed, and may be other setting conditions that can be set during shooting, such as an aperture value. In that case, display screens for different shooting conditions may be switched by operating a switch such as the selection switch 192, or the shooting conditions to be displayed may be selected in advance. Considering this case, the configuration of the photographing condition display screen when the photographing condition to be displayed is set as an aperture value is shown below as a modification of the present embodiment.

[Modification 1]
Hereinafter, a first modification of the first embodiment of the present invention will be described with reference to FIG.
FIG. 9 is a diagram showing an imaging condition determination area 620 of the display unit 170 according to this modification. In addition, the same code | symbol is attached | subjected to the thing similar to a 1st Example, and the description is abbreviate | omitted. Further, the flow of the processing operation of the configuration of the imaging apparatus and the flowchart of the imaging operation is not changed except that S730, 731, 740, and 741 in FIG. Further, as described above, in this modification, the imaging conditions of the imaging optical systems 111a, 112a, 113a, and 114a to be displayed are the aperture values of the optical system.

  In FIG. 9, the difference from the first embodiment is the display position of a plurality of indicators (622 in FIG. 6) indicating the set value of the imaging condition corresponding to a predetermined focal length and the display position of the result indicator (623). is there. First, the result indicator will be described.

  In this modification, as in the first embodiment, the result indicator is not displayed in association with the focal length display 621 of each imaging optical system, but the focal length display 621b of the imaging optical system 111b is displayed. Displayed between the display 621c. Further, the result indicator 940 of this modification example is a pair of two types of displays. Since the shooting condition to be changed in the present modification is an aperture value, a result indicator 940a that suggests a shooting result in which the brightness of the subject becomes bright and a result indicator 940b that suggests a shooting result in which the brightness of the subject becomes dark are provided. indicate. Accordingly, when the aperture value is changed by operating the indicator 622 toward the result indicator 940a, it is possible to indicate to the user that the photographed subject image becomes brighter, and vice versa.

  The two types of result indicators 940a and 940b are configured to be displayed together as a pair, and the display position is set substantially at the center of the focal length display 621 of the imaging optical systems 111a, 112a, 113a, and 114a. This means that when shooting with the aperture value changed, the brightness of the subject changes regardless of the imaging optical system, and it suggests that the imaging results are common to each imaging optical system. This is to make them recognize.

  However, the present invention is not limited to this, for example, as will be described later, when changing the imaging conditions of a specific imaging optical system, the result is in the vicinity of the focal length display (any one of 621a to 621d) of the imaging optical system. An indicator 940 may be displayed.

  Next, the indicator 622 representing the set aperture value will be described.

  In FIG. 9, unlike the first embodiment, two types of indicators 922f and 922g are displayed at the position of the indicator 622d of the imaging optical system 114a among the indicators 622 for setting the imaging conditions. Among them, the indicator 922f is displayed at the position of an aperture value (for example, F3.5) set in common to each imaging optical system. This is to show that the aperture value F2.8 cannot be set (cannot be operated) due to the optical system of the imaging optical system 114a or the aperture diameter of a diaphragm (not shown) included in the imaging optical system 114a. Further, the display form of the indicator 922f is different from the indicators 622a to 622c (and 622d) (in FIG. 9, the outer periphery of the indicator 922f is a broken line). Thereby, the user can easily recognize that the indicator 922f cannot be operated by the switch unlike the indicators 622a to 622c.

  Further, when the setting of the shooting condition can be changed by directly operating the surface of the display unit 170, the setting that does not move from the display position in the shooting condition determination area 620 even if the user tries to directly operate the indicator 922f. To. On the other hand, the indicators 322a to 322c are set so that the aperture value, which is the imaging condition of the imaging optical systems 111a to 113a, can be changed according to the operation position when the user directly operates, as in the first embodiment. . Accordingly, the user can be informed that the indicator 922f cannot be operated, that is, cannot be set as a shooting condition, and the convenience of the imaging apparatus can be improved.

  On the other hand, the indicator 922g is a maximum value of the open aperture value of the imaging optical system 114a (in this modification example, depending on the aperture of the optical system of the imaging optical system 114a and the aperture of a diaphragm (not shown) included in the imaging optical system 114a). F5.6). The indicator 922g is set to be operable by the user using the selection switch 192 and the determination switch 193, like the indicators 622a to 622c. As described above, even when the surface of the display unit 170 is directly operated, the indicator 922g is set to be operable. Thereby, it is possible to change the aperture value, which is the imaging condition of the imaging optical system 114a. Further, the display form of the indicator 922g is different from the indicators 622a to 622c (and 622d) (in FIG. 9, the inside of the indicator 922g is filled). Accordingly, the user can easily recognize that the indicator 922g is different from the indicators 622a to 622c and 622f, and the convenience of the imaging apparatus can be improved.

  In the configuration of the above-described modification, as a plurality of indicators indicating the setting value of the imaging condition corresponding to the predetermined focal length, the display regarding the value of the imaging condition that cannot be set for the predetermined focal length and the upper limit of the settable value A set of indications. Thus, the user can individually change / set the imaging conditions of the imaging optical systems 111a to 114a while recognizing the aperture value and the maximum aperture value that cannot be set by operating the indicators 622a to 622c and 922g. It becomes possible. Further, when the indicators 622a to 622c and 922g are operated, the result indicator 940 is displayed, so that the user can check the photographing result when the photographing condition is changed before photographing.

  In this modified example, as in the first example, the result indicator 940 may be displayed at a position corresponding to each of the imaging optical systems 111a to 114a. In that case, it goes without saying that the same effect as described in the first embodiment can be obtained. Further, as mentioned in the first embodiment, a display control configuration that can selectively display the shutter speed display screen of the first embodiment and the aperture value display screen of the present modification may be employed.

  As described above, in an imaging apparatus that simultaneously captures optical images of a plurality of focal lengths, it is possible to display the shooting conditions set for capturing each optical image on the shooting condition display screen. An imaging device with improved performance can be provided. In particular, since the result indicators 940a and 940b are displayed, when the indicators 622a to 622c and 922g are changed in any direction of the result indicators 940a and 940b, how to change the shooting result is checked before shooting. I can do it. Therefore, an imaging device with improved convenience can be provided.

[Modification 2]
Hereinafter, with reference to FIG. 10, a further modification of the first modification will be described as a second modification.

  FIG. 10 shows an imaging condition determination area 620 of the display unit 170. The same elements as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. Further, the flow of the processing operation of the configuration of the imaging apparatus and the flowchart of the imaging operation is not changed except that S730, 731, 740, and 741 in FIG. Similarly to the first modified example, the aperture value of the optical system is displayed as the imaging condition of each imaging optical system 111a, 112a, 113a, 114a.

  In FIG. 10, the difference from the first modified example is that two types of indicators 1022h and 1022j are displayed at the position of the indicator 622d of the imaging optical system 114a among the indicators 622 for setting the imaging conditions. is there.

  The indicator 1022h is displayed at the position of an aperture value (for example, F3.5) set in common to each imaging optical system, like the indicator 1022f. This is because, as in the first modification, the aperture value F2.8 cannot be set due to the optical system of the imaging optical system 114a and the aperture diameter of the diaphragm (not shown) included in the imaging optical system 114a. It is for showing. However, in this case, the indicator 1022h is different from the indicator 922f in that the indicator 1022h is set to be operable. Accordingly, the user uses the selection switch 192 and the determination switch 193, or directly operates the surface of the display unit 170 to operate the indicator 1022h, thereby changing the aperture value that is the imaging condition of the imaging optical system 114a. Is possible.

  In this case, in this modification, when the value is changed to a value larger than the maximum open aperture value of the imaging optical system 114a (for example, F8.0 shown in FIG. 10B), the display form of the indicator 1022h is changed to 1022k, It becomes the same display form as the other indicator 622c. Thereby, the user can recognize that the aperture value, which is the imaging condition of the imaging optical system 114a, can be changed from the maximum aperture value, and the convenience of the imaging apparatus can be improved. In addition, by changing the display mode when the indicator 1022h is operated, it is possible to visually identify whether the aperture value changed by the operation is larger or smaller than the maximum open aperture value of the imaging optical system 114a. Is possible.

  On the other hand, the indicator 1022j, like the indicator 1022g, has a maximum aperture value (this deformation) of the imaging optical system 114a depending on the optical system of the imaging optical system 114a and the aperture diameter of a diaphragm (not shown) included in the imaging optical system 114a. In the example, F5.6) is shown. The indicator 1022j is different from the indicator 922g in that the indicator 1022j is set not to move from the position provided in the shooting condition determination area 620 even if the user tries to directly operate the indicator 1022j.

  That is, the maximum aperture value of the imaging optical system 114a is determined by the optical system of the imaging optical system 114a and the aperture diameter of the diaphragm (not shown) included in the imaging optical system 114a. I can't. Therefore, by setting the indicator 1022j so that the user cannot operate it, the user is notified that the maximum aperture value cannot be changed, and the convenience of the imaging apparatus is improved.

  Also in this modified example described above, the same technical effect as in the first modified example can be obtained.

  In the present invention, the imaging device 100 is a camera integrated with a lens. However, the present invention is not limited to this, and the same technical effect as described above can be obtained even when the lens is detachable. Needless to say.
