Description

  The present invention relates to a technique for improving the operability of an image processing selection setting operation performed with a shooting operation in a shooting device such as a digital camera.

  Conventionally, an optical image formed by a photographing optical system is sequentially converted into an image signal by a photoelectric conversion element such as a solid-state imaging element, and an image display device such as a liquid crystal display device (LCD) is converted from the obtained image signal. The image signal is converted into image data (still image data or moving image data) in a predetermined format and recorded on a recording medium, and the image recorded on the recording medium. Imaging devices such as digital cameras and video cameras configured to reproduce and display data on the image display device as images are generally put into practical use and widely used.

  The imaging apparatus of such a form has a feature that various image outputs can be easily obtained by performing various signal processing on the acquired image signal (output signal of the image sensor). For example, in this type of photographing device, when photographing a subject, not only a two-dimensional image that reproduces the form and color of the subject as faithfully as possible but also the photographer's Some have a function called a so-called special effect filter image processing function or the like that can generate a so-called pictorial image that is different from what a human sees in consideration of the impression and creative intention.

  On the other hand, in a conventional photographing apparatus, an optical member such as glass colored on the front surface of the photographing lens, a glass (optical member) formed so that the transmittance in the vicinity of the periphery and the central portion is different, or an optical member (glass) Shooting by coloring the light flux that passes through the photographic lens or adjusting the amount of light by placing so-called special effect filters such as causing the transmitted light to blur or refraction by various processing on the surface Shooting techniques that make the impression of a subject image formed by a lens different have been put into practical use for a long time.

  The above-mentioned special effect filter image processing function is a function that obtains an image effect obtained by a conventional imaging technique using a special effect filter by performing electrical image processing on the acquired image signal. It is.

  In a conventional photographing method using an optical special effect filter, it is necessary to attach a filter according to the purpose of drawing on the front surface of the photographing lens every time a photographing operation is performed. Therefore, there is a problem that it takes time and labor to attach and remove those filters, and it is necessary to carry a plurality of filters, and it cannot be said that this is a photographing method that can be easily performed by general users. There was a problem.

On the other hand, in the imaging apparatus that has been widespread in recent years, it is possible to obtain an image effect almost equivalent to that of the optical special effect filter by performing image processing on the acquired image signal by the special effect filter image processing function as described above. It is like that. Further, in recent years, special effect images with various image effects can be generated with rapid progress of digital image processing technology. For example, an image effect equivalent to that obtained by placing various optical filters (for example, a color conversion filter, a contrast adjustment filter, etc.) on the front surface of the taking lens,
Image effects equivalent to those obtained using special-purpose photographic lenses (for example, fish-eye lenses and photographic lenses with tilt mechanisms)
Various proposals for realizing image effects and the like obtained by changing various setting values when performing adjustments on image signals such as exposure adjustment, white balance adjustment, and color balance adjustment are proposed by Japanese Patent Application Laid-Open No. 2005-347886, for example. Has been put to practical use.

  The conventional photographing apparatus disclosed in Japanese Patent Application Laid-Open No. 2005-347886 and the like has a configuration in which a touch panel is provided and various settings are selected by a user performing a touch operation. In this case, various setting items are selected and set using a menu format having a hierarchical structure.

JP-A-2005-347886

  However, in the menu-type operation system disclosed in the above Japanese Patent Application Laid-Open No. 2005-347886 and the like, for example, in order to perform various settings, a large number of selection items in the upper layer of the hierarchical structure are used. In order to make the desired selection settings quickly and reliably, such as the need to navigate to a deeper selection item for more detailed settings, the menu hierarchy must be understood to some extent. There is a problem that it is necessary to make a change and an intuitive switching operation cannot be performed.

  The present invention has been made in view of the above-described points, and an object of the present invention is to provide a function of performing various signal processing on an image signal acquired using an image sensor to obtain a desired image effect. Provided is a photographic device that allows a user to quickly and surely and intuitively perform various selection setting operations related to signal processing for obtaining an image effect in the provided photographic device, and thus has good operability. That is.

  In order to achieve the above object, an imaging device of one embodiment of the present invention displays an image based on image data acquired by the imaging unit including the imaging optical system, and an operation icon. An image for performing image processing on the image data acquired by the display unit, the touch panel disposed on the surface of the display unit, the touch slide determination unit for determining an operation input to the touch panel, and the imaging unit A control unit including a processing unit and a display control unit configured to control the display unit, wherein the control unit determines a touch slide operation on the operation icon by the touch slide determination unit, and the determination result The image processing unit performs image processing on the image data acquired by the imaging unit based on the image, and displays an image based on the image data generated as a result on the display unit His carried out by the display control unit.

FIG. 6 is a diagram showing that the filter effect is changed by operating the filter icon after the state of FIG. FIG. 7 is a flowchart showing a main sequence of device control of the photographing device of the present embodiment.

  First, the user holds the photographing device 10 using both hands in a state where the photographing device 10 is in a power-on state and is set to a photographing mode capable of performing a photographing operation, for example. The holding method is the same as the method performed by a conventional photographing apparatus. That is, as shown in FIG. 2, the right hand 120 </ b> R holds the left side when viewed from the front of the photographing apparatus 10. At this time, the index finger of the right hand 120R is, for example, in a position where it can be applied to the shutter button 17c as shown in FIGS. 2 and 3, and the right hand 120R thumb 120Rb is viewed from the back of the photographing apparatus 10 as shown in FIG. It is a part located on the right side of the main body as viewed, and is freely arranged in the vicinity region including the region indicated by symbol A in FIG. On the other hand, as shown in FIG. 2, the left hand 120L holds the lens barrel holding the lens 12a so as to be grasped from below.

  At this time, the photographing apparatus 10 is in the power-on state and in the photographing mode as described above. Therefore, a so-called live view image is displayed on the display screen of the display unit 18 on the back side of the photographing apparatus 10 as shown in FIG.

  In the state shown in FIG. 3, the user causes the thumb 120 </ b> Rb of the right hand 120 </ b> R to enter the region indicated by the symbol A of the display unit 18 from the region outside the display screen of the display unit 18. At this time, with the thumb 120Rb of the right hand 120R, a touch and slide operation is performed to slide the surface of the touch panel 17b arranged over the display unit 18. In the photographing apparatus 10, the special effect filter image processing mode is activated by performing this operation. In this way, when the special effect filter image processing mode is activated, as shown in FIG. 4, a filter icon 21 that is an operation icon is placed in a predetermined area of the display unit 18 corresponding to the area indicated by the symbol A in FIG. 3. Is displayed.

  As a form of the filter icon 21, for example, as shown in FIG. 4 and the like, a form of a display icon that is simulated in a manner similar to a conventional optical filter is conceivable. That is, in the example shown in FIG. 4 etc., it is a substantially circular icon display, and a filter name display 21a indicating the filter effect type in a predetermined area inside the circle, an up / down slide bar display 21b for applying the filter effect, etc. Is displayed, and an icon ring display 21c for setting an application level, such as a gradation or strength adjustment of the filter effect, is displayed on the outer peripheral edge of the circle. In addition, there are two areas shown in the circular shape of the filter icon 21 with the vertical slide bar display 21b interposed therebetween, one of which is an area 21e and the other is an area 21d. In addition, a design contrivance is made such that, for example, a notch or the like is given to a portion that the user touches when performing a touch & slide operation, such as the vertical slide bar display 21b and the icon ring display 21c. As a result, the user can intuitively understand that those parts are operation parts, and there is an effect that the user can contribute to improvement in operability.

The filter icon 21 having such a form is displayed on the display unit 18. When the user performs a touch operation or a slide operation on the icon 21 via the touch panel 17b, the touch slide determination unit 11c of the image processing control unit 11 is performed. These operations are determined, and the corresponding control is performed based on the determination result.
The display form of the filter icon 21 is not limited to this example, and various forms can be considered, and any display form can be applied.

  The state of FIG. 4 shows a state where the special effect filter image processing mode is activated and the filter icon 21 is displayed. In this state, one of a plurality of types of filter effects prepared in advance is selected, and the filter name display 21a of the selected filter effect type is displayed as “Art”. Note that the state of FIG. 4 is a state where the special effect filter image processing has not yet been executed. Therefore, a normal live view image before special effect filter image processing is displayed on the display unit 18 of the photographing apparatus 10 shown in FIG.

  In the state of FIG. 4, the user touches and slides in a direction corresponding to the arrow X shown in FIG. 5 while touching a portion corresponding to the vertical slide bar display 21 b with the thumb 120 </ b> Rb of the right hand 120 </ b> R. Manipulate. Then, the vertical slide bar display 21 b moves in the arrow X direction inside the circular shape of the filter icon 21. With the movement of the vertical slide bar display 21b, the live view image display on the display unit 18 is switched from the upper edge portion to the lower edge portion of the display screen to the display after the special effect filter image processing.

  That is, as the vertical slide bar display 21b moves in the arrow X direction, the area of one area 21e of the circular inner area of the filter icon 21 gradually increases and the area of the other area 21d gradually decreases. Display form. In this case, the area of one region 21e indicates a region to which special effect filter image processing is applied, and the area of the other region 21d indicates an unapplied region of the image processing. Therefore, the displacement of the area of the one region 21e and the other region 21d corresponds to the progress state of the special effect filter image processing for the live view image display of the display unit 18.

  When the vertical slide bar display 21b is finally moved to the lowermost end of the circular inner area of the filter icon 21, as shown in FIG. 6, the vertical slide bar display 21b is fixed in place and simultaneously displayed on the display unit 18. The live view image display is also a display in which the special effect filter image processing has been applied over the entire area. In this state, the icon ring display 21c of the filter icon 21 is touch-operated, and the touch-and-slide operation is performed in the arrow R direction shown in FIG. Thereby, it is possible to adjust the density or strength of the filter effect. In this case, the icon ring display 21c is linked to the touch and slide operation in the direction of arrow R in FIG. 6 to display one of the circular inner areas 21e, that is, the special effect filter image processing applied area, for example, The display changes the shade, brightness, etc., and at the same time, the live view image display also reflects the shade and strength of the corresponding filter effect. Here, instead of touching and sliding the icon ring display 21c in the rotation direction (arrow R direction in FIG. 6), the lens ring 12c is rotated to similarly adjust the density or strength of the filter effect. You may do it.

  When the special effect filter image processing setting is thus determined, the shooting operation is executed by performing a release operation by pressing the shutter button 17c or a touch operation on the touch panel 17b as in a normal shooting operation. As a result, still image shooting is performed if the set shooting operation mode is the still image shooting mode, and moving image shooting is started if the set shooting operation mode is the moving image shooting mode. Then, in response to the release operation again, the moving image shooting is completed.

  As described above, in the present embodiment, when the special effect filter image processing mode is activated, the filter icon 21 is displayed on the display unit 18, and a filter effect application operation or its operation can be performed by touching and sliding the filter icon 21. Settings are made. The series of operations is a pseudo operation similar to an operation of arranging an optical filter on the front surface of a lens in a conventional photographing apparatus. Then, by devising the form of the filter icon 21, the operation system can be intuitively operated by the user.

Next, a device control main sequence of the photographing device 10 of the present embodiment will be described with reference to the flowchart of FIG.
First, when the imaging device 10 is powered on, the signal processing and control unit 11 performs initialization processing for the entire device. This initialization process is the same as a process generally performed in a conventional photographing apparatus, and a detailed description thereof is omitted. Then, when the initialization process is completed, the signal processing and control unit 11 of the photographing apparatus 10 executes the processing sequence of FIG.

  In step S101, the signal processing and control unit 11 monitors the operation determination unit 15 to check whether or not the currently set operation mode is set to the shooting mode. If it is confirmed that the shooting mode is set, the process proceeds to the next step S102. If it is confirmed that an operation mode other than the shooting mode is set, the process proceeds to step S211.

  In step S <b> 102, the signal processing and control unit 11 controls the imaging unit 12 and the display unit 18 to execute live view image display processing for sequentially displaying images based on the image data acquired by the imaging unit 12.

  In addition, here, the touch and slide operation in which the user enters the right hand 120R thumb 120Rb from the area outside the display screen of the display unit 18 into the area indicated by the symbol A of the display unit 18 (described with reference to FIGS. 3 and 4). When the operation is performed, the touch slide determination unit 11c of the signal processing and control unit 11 receives the input signal from the touch panel 17b and activates the special effect filter image processing mode. Accordingly, the display control unit 11 a of the signal processing and control unit 11 controls the display unit 18 to display the filter icon 21. Thereafter, the process proceeds to step S103.

  In step S103, the signal processing and control unit 11 checks whether or not the special effect filter image processing has already been applied. If it is confirmed that special effect filter image processing has been applied, the process proceeds to step S104.

In step S104, the signal processing and control unit 11 monitors a signal from the touch slide determination unit 11c and confirms whether or not the vertical slide bar display 21b of the filter icon 21 has been slid upward. In this case, the upward sliding operation of the vertical slide bar display 21b is an operation for canceling application of the special effect filter image processing. Here, when the upward sliding operation of the vertical slide bar display 21b is confirmed, the process proceeds to step S105, and in step S105, the signal processing and special effect image processing unit of the imaging control unit 11b of the control unit 11 is performed. 11ba cancels the applied special effect filter image processing. As a result, the live view image displayed on the display unit 18 returns to the normal live view display. Thereafter, the process proceeds to step S111.
Further, if the upward sliding operation of the upper and lower slide bar display 21b is not confirmed in the process of step S104 described above, the process proceeds to step S108.

On the other hand, if it is confirmed in step S103 described above that the special effect filter image processing has not been applied yet, the process proceeds to step S106.
In step S106, the signal processing and control unit 11 monitors the signal from the touch slide determination unit 11c and confirms whether or not the vertical slide bar display 21b of the filter icon 21 has been slid downward. In this case, the downward sliding operation of the vertical slide bar display 21b is an operation for applying special effect filter image processing as described above. Here, when the downward sliding operation of the vertical slide bar display 21b is confirmed, the process proceeds to step S107, and in step S107, the signal processing and special effect image processing unit of the photographing control unit 11b of the control unit 11 is performed. 11ba applies special effect filter image processing of the type set and selected. As a result, the normal live view image being displayed on the display unit 18 is switched to the corresponding live view image that has been processed with the special effect filter image. Thereafter, the process proceeds to step S108.
In step S106 described above, if the downward sliding operation of the vertical slide bar display 21b is not confirmed, the process proceeds to step S111.

  Next, in step S108, the signal processing and control unit 11 monitors the touch slide determination unit 11c and the operation determination unit 15, and determines whether or not a rotation slide operation of the icon ring display 21c or a rotation operation of the lens ring 12c has been performed. Confirm. As described above, these operations are operations for adjusting the density or strength of the filter effect. Here, when the rotation operation of the icon ring display 21c or the lens ring 12c is confirmed, the process proceeds to the next step S109. If the rotation operation of the icon ring display 21c or the lens ring 12c is not confirmed, it is determined that the settings of the filter effect density or intensity adjustment have already been determined, and the process proceeds to step S111.

  In step S109, the signal processing and control unit 11 determines the rotation amount of the icon ring display 21c or the lens ring 12c based on the output signals from the touch slide determination unit 11c and the operation determination unit 15, that is, the intensity or adjustment amount of the filter effect. Is switched and the setting of the filter effect density or strength adjustment is finalized. Thereafter, the process proceeds to step S111.

  Next, in step S111, the signal processing and control unit 11 monitors a signal from the operation determination unit 15 or the touch slide determination unit 11c, and whether or not a release signal for starting a still image shooting operation has occurred. Confirm. If a release signal for still image shooting is confirmed, the process proceeds to the next step S112. If no release signal for still image shooting is confirmed, the process proceeds to step S121.

  In step S112, the signal processing and control unit 11 controls the imaging unit 12 through the imaging control unit 11b and simultaneously controls the display unit 18 through the display control unit 11a to execute a normal still image shooting operation. To do. Thereafter, the process proceeds to step S121.

  In step S121, the signal processing and control unit 11 monitors a signal from the operation determination unit 15 or the touch slide determination unit 11c and confirms whether or not a release signal for starting a moving image shooting operation is generated. . If a release signal for moving image shooting is confirmed, the process proceeds to the next step S122. If the release signal for moving image shooting is not confirmed, the process returns to the above-described step S101 and the subsequent processes are repeated.

  In step S122, the signal processing and control unit 11 controls the imaging unit 12 via the shooting control unit 11b and simultaneously controls the display unit 18 via the display control unit 11a to execute a normal moving image shooting operation. . Thereafter, the process proceeds to step S123.

  In step S123, the signal processing and control unit 11 monitors a signal from the operation determination unit 15 or the touch slide determination unit 11c and confirms whether or not a moving image shooting operation end signal has been generated. If a moving image shooting end signal is confirmed, the process proceeds to the next step S124. If the moving image shooting end signal is not confirmed, the process returns to the above-described step S102 and the subsequent processes are repeated.

  In step S124, the signal processing and control unit 11 controls the imaging unit 12 via the shooting control unit 11b, and simultaneously controls the display unit 18 via the display control unit 11a to execute the moving image shooting operation end process. . And the recording operation to the recording part 14 of the still image data acquired by the process of the above-mentioned step S112 or the moving image data acquired by the process of the above-mentioned steps S122-S123 is performed. Thereafter, the processing returns to step S101, and the subsequent processing is repeated.

  On the other hand, when it is confirmed in step S101 described above that an operation mode other than the shooting mode has been set and the process proceeds to step S211, the signal processing and control unit 11 performs operation determination in step S211. The unit 15 is monitored to check whether or not the currently set operation mode is set to the reproduction mode. If it is confirmed that the playback mode is set, the process proceeds to the next step S212. If the playback mode is not set, the process returns to the above-described step S101 and the subsequent processes are repeated.

  In step S212, the signal processing and control unit 11 drives and controls the display unit 18, the recording unit 14, and the like to start normal image reproduction processing. Here, first, thumbnail images of a plurality of image data recorded in the recording unit 14 are read, and a file list display process is performed on the display unit 18. Thereafter, the process proceeds to step S213.

  Subsequently, in step S213, the signal processing and control unit 11 monitors the operation determination unit 15 and confirms whether or not an instruction signal accompanying a selection operation for an image file desired to be reproduced has been generated. If the file selection instruction signal is confirmed, the process proceeds to the next step S214. If the file selection instruction signal is not confirmed, the process proceeds to step S216. In step S216, the signal processing and control unit 11 monitors the operation determination unit 15 to end the reproduction operation. Check if a signal is generated. Here, when the end instruction signal is confirmed, the process returns to the above-described step S101, and the subsequent processes are repeated. If the end instruction signal is not confirmed, the process returns to the above-described step S212 and the subsequent processes are repeated.

  When the file selection instruction signal is confirmed in the process of step S213 and the process proceeds to step S214, in step S214, the signal processing and control unit 11 records the corresponding selected image file in accordance with the selection instruction signal. 14 is read out and displayed and reproduced using the display unit 18.

  Subsequently, in step S215, the signal processing and control unit 11 monitors the operation determination unit 15 and confirms whether or not a reproduction end instruction signal for ending the image reproduction processing during reproduction display has occurred. Here, when the reproduction end instruction signal is confirmed, the processing returns to the above-described step S212, and the subsequent processing is repeated. In this processing step, the image reproduction process is continued until the reproduction end instruction signal is confirmed.

  As described above, according to the first embodiment, when the special effect filter image processing mode is activated, the filter icon 21 is displayed on the display unit 18, and the filter effect is displayed by touching and sliding the filter icon 21. Application operations and settings are performed. These series of operations are pseudo-operations similar to the work of arranging an optical filter on the front surface of a lens in a conventional photographing apparatus, and therefore the user can operate intuitively. Also, in shooting with the special effect filter image processing mode activated, various operations need only be performed intuitively and simply, so that you can concentrate on shooting, and the amount of operation for touch and slide operations on icons Because it requires less, it can be operated with a part of the hand (one thumb) that holds the device, for example, camera shake can be suppressed, operation can be performed more quickly, operation results can be confirmed, and operation settings can be made. Etc. can be easily confirmed.

[Second Embodiment]
Next, a photographing apparatus according to a second embodiment of the present invention will be described below with reference to FIGS. FIG. 8 is a block diagram showing the internal configuration of the photographing apparatus according to the second embodiment of the present invention.

  The basic configuration of this embodiment is substantially the same as that of the first embodiment described above. That is, the photographing apparatus 10A according to the present embodiment includes an eyepiece display unit 19 and an eyepiece in the form of a finder, in addition to the rear display unit 18 corresponding to the display unit 18 in the first embodiment as a display system configuration block. 19b (refer FIG. 11) differs.

  The eyepiece display unit 19 is a so-called electronic view finder (EVF). Specifically, for example, a small LCD or an organic EL display is applied to the eyepiece display unit 19. The eyepiece display unit 19 includes various images displayed on the display unit 18 in the first embodiment described above (in this embodiment, the rear display unit 18), that is, live view images (in shooting mode), reproduced images. In addition to (in playback mode), various setting menus are displayed (in shooting mode and playback mode), and the filter icon 21 and the like in the special effect filter image processing mode are displayed in exactly the same manner as the display unit 18. obtain. Note that one of the eyepiece display unit 19 and the rear display unit 18 operates alternatively. The eyepiece display unit 19 and the rear display unit 18 are both driven and controlled by the display control unit 11a.

  Further, in the photographing apparatus 10A of the present embodiment, the eye sensor 16 is disposed on the back side of the photographing apparatus 10A and in the vicinity of the eyepiece portion of the eyepiece display section 19 with the provision of the eyepiece display section 19. Has been. This eye sensor 16 detects the posture of the user observing the display of the eyepiece display unit 19 through the eyepiece lens 19b, that is, the user's face approaching the back of the photographing apparatus 10A so as to look into the eyepiece lens 19b. Thus, it is a sensor that determines the state of using the eyepiece display unit 19. Other configurations are the same as those in the first embodiment described above. Therefore, those constituent members are denoted by the same reference numerals, and detailed description thereof is omitted.

The operation when using the imaging apparatus 10A of the present embodiment configured as described above will be described below with reference to FIGS.
FIG. 9 is a diagram showing a state when the photographing apparatus of the present embodiment is held in hand (corresponding to FIG. 2 of the first embodiment). FIG. 10 is a view showing the state of FIG. 9 when viewed from the back side of the photographing apparatus (corresponding to FIG. 3 of the first embodiment). FIG. 11 is a schematic block diagram showing a schematic configuration of the photographing apparatus of the present embodiment. FIG. 12 is a view showing that the filter icon is displayed on the rear display unit and the live view image is formed on the eyepiece display unit in the state of FIG. 10 (corresponding to FIG. 4 of the first embodiment). FIG. 13 is a diagram showing a display state of the rear display unit and the eyepiece display unit when the filter icon is operated in the state of FIG. 12 (corresponding to FIG. 5 of the first embodiment). FIG. 14 is a diagram illustrating a state in which an operation for hiding the filter icon is performed when the special effect filter image processing mode is activated in the photographing apparatus of the present embodiment. FIG. 15 is a diagram showing an operation in which the filter icon is displayed again from the state of FIG. FIG. 16 is a main flowchart of device control of the photographing device of this embodiment.

  When performing a photographing operation using the photographing apparatus 10A of the present embodiment, the user holds the photographing apparatus 10 with both hands (see FIG. 9), as in the first embodiment (see FIG. 2). . When the eyepiece display unit 19 is used, the user places a face in the vicinity of the eyepiece lens 19b as shown in FIG. 11 and moves the eyepiece portion where the eyepiece lens 19b is disposed with the eye 101. The display screen of the eyepiece display unit 19 can be observed by looking in.

  At this time, a live view image as indicated by reference numeral 19a in FIG. 12 is displayed on the display screen of the eyepiece display unit 19. Further, in the state shown in FIG. 10, the user performs a touch-and-slide operation for intruding the thumb 120 </ b> Rb of the right hand 120 </ b> R from the area outside the display screen of the rear display unit 18 into the area indicated by the symbol A of the rear display unit 18. Then, the special effect filter image processing mode is activated. As a result, only the filter icon 21 as shown in FIGS. 10 and 12 is displayed in the predetermined area of the rear display unit 18. In addition, the display form of the filter icon 21 in this embodiment is the same as that of the above-described first embodiment.

  Note that the state of FIG. 12 is a state in which special effect filter image processing has not yet been executed. Therefore, in the state shown in FIG. 12, a normal live view image before special effect filter image processing is displayed on the display screen 19a of the eyepiece display unit 19 of the photographing apparatus 10A.

In the state shown in FIG. 12, the user touches and slides the vertical slide bar display 21b in the arrow X direction shown in FIG. 13 with the thumb 120Rb of the right hand 120R in the state shown in FIG. As a result, the vertical slide bar display 21b moves in the direction of the arrow X within the circular shape of the filter icon 21, and as the vertical slide bar display 21b moves, the live view image display on the display screen 19a of the eyepiece display unit 19 is displayed. The display is switched to the special effect filter image processed display (see FIG. 13). Accordingly, when the vertical slide bar display 21b is moved in the direction of the arrow X, it is possible to overlook the applied area and the unapplied area of the special effect filter image processing. Can be compared.
Further, the area ratio between the applied region and the unapplied region can be changed according to the slide amount. That is, when the vertical slide bar 21b is slid by half of the total movement amount, the filter image processing effect can be applied to the upper half area of the entire screen. As described above, the amount of operation of the upper and lower slide bars 21b of the filter icon 21 is set to be proportional to the image processing range area reflected in the live view image displayed on the display unit.
Further, the amount of operation of the filter icon 21 is such that it can be operated only with the thumb, but the region reflected on the display image of the display unit by the operation is finally the entire screen. Therefore, it is possible to quickly perform shooting using special effect filter image processing with a small amount of operation, and the same icon filter 21 is used for switching operations for various settings in the image processing mode. Operability can be realized. Further, since the mode can be switched by the intrusion of the thumb into the display screen, the mode switching operation can be performed with only a slight movement of the thumb. In addition, this means that the finger holding the photographing device 1 is diverted for other operations, but the amount of operation with the thumb away from the holding of the device may be extremely small, and thus during the photographing operation. Image quality deterioration due to shaking or movement of the device, such as a so-called camera shake that may occur when the device is held, can be suppressed.

  Also in the present embodiment, in a state where application of the special effect filter image processing has been completed, it is possible to adjust the density or strength of the filter effect by touching and sliding in the rotation direction of the icon ring display 21c. Is the same as in the first embodiment described above. In addition, instead of the touch and slide operation in the rotation direction of the icon ring display 21c, the lens ring 12c may be rotated to adjust the density or strength of the filter effect. This is the same as the embodiment.

Furthermore, also in this embodiment, it is possible to perform a photographing operation using only the rear display unit 18 without using the eyepiece display unit 19. The operation in that case is exactly the same as in the first embodiment described above.
On the other hand, in the present embodiment, the eyepiece display unit 19 and the rear display unit 18 are alternatively used to perform a shooting operation or the like, but the present invention is not limited to this. For example, when the live effect image display is performed using the eyepiece display unit 19 and the special effect filter image processing mode is activated, the filter icon 21 is displayed on the rear display unit 18 as described above. (See FIG. 12). At this time, live view image display may be performed on the rear display unit 18 in addition to the eyepiece display unit 19. When the application of the special effect filter image processing is started by the vertical sliding operation of the filter icon 21, one of the eyepiece display unit 19 and the rear display unit 18 displays a normal live view image, and the other displays a special live view image. The live view image that has been processed with the effect filter image is displayed. With such a configuration, the images before and after application of the image processing effect can be displayed on each of the two display units, so that the images before and after application can be compared.

  The filter icon 21 is displayed while the special effect filter image processing mode is activated. In addition, the filter icon 21 is displayed on the right hand of the user while the special effect filter image processing mode is activated. The filter icon 21 may be displayed only when the thumb 120Rb is within a predetermined area of the rear display unit 18 (refer to the area indicated by symbol A in FIG. 3).

  For example, if the filter icon 21 is always displayed, the user can always recognize that the special effect filter image processing mode is activated. On the other hand, if the filter icon 21 is always displayed, a part of the live view display screen is hidden, which may cause trouble when performing composition determination, for example. Therefore, if the filter icon 21 can be appropriately hidden at a desired time, a state in which the entire live view display screen can be displayed even when the special effect filter image processing mode is activated can be displayed. There is an advantage that composition determination and the like can be performed without hindrance.

  Furthermore, in the photographing apparatus 10A of the present embodiment, the filter icon 21 is displayed only when the user's right thumb 120Rb is within a predetermined area of the rear display unit 18 (see the area indicated by symbol A in FIG. 3). When the slide operation in which the right thumb 120Rb moves outside the predetermined area is detected, the special effect filter image processing mode is canceled and the filter icon 21 is deleted. Instead, for example, a normal shooting setting icon (hereinafter abbreviated as a normal icon) 31 as shown in FIG. 14, that is, a setting icon corresponding to flash emission setting, macro shooting setting, exposure correction setting, and the like is displayed. And may be controlled so that the setting can be appropriately changed by a touch operation or a touch & slide operation (see FIG. 14). .

  When such a setting change operation is finished, if the right thumb 120Rb is moved into the predetermined area by a slide operation at any time, the filter icon 21 is immediately displayed and the special effect filter image processing mode is activated (see FIG. 15).

  As described above, in the present embodiment, when the shooting operation is performed while observing the live view image using the eyepiece display unit 19, when the special effect filter image processing mode is activated, the rear display unit 18 is used for filtering. An icon 21 is displayed. In this case, the touch and slide operation of the filter icon 21 on the rear display unit 18 can be performed without trouble while looking through the eyepiece display unit 19. At the same time, since the filter icon 21 is not displayed on the finder image (live view image) of the eyepiece display unit 19, it is possible to concentrate on determining the composition while observing the finder image.

  Further, when the photographing operation is executed using only the rear display unit 18 (including the above-described first embodiment), when the special effect filter image processing mode is activated, the filter icon 21 of the rear display unit 18 is appropriately set. By performing the non-display state control, it is possible to determine the composition while observing the rear display unit 18 without any trouble.

  Next, a device control main sequence of the photographing device 10A of the present embodiment will be described with reference to the flowchart of FIG. The apparatus control main sequence in the imaging apparatus 10A of the present embodiment is substantially the same as the main sequence (FIG. 7) of the first embodiment described above. Therefore, in the present embodiment, the same processing steps in the above-described first embodiment are given the same step numbers and description thereof is omitted, and only different processing steps are described in detail below.

  In step S101, the signal processing and control unit 11 monitors the operation determination unit 15 to check whether or not the currently set operation mode is set to the shooting mode. The processing in step S101 is the same as that in the first embodiment (FIG. 7).

  If it is confirmed in step S101 that the camera is set to a mode other than the shooting mode, the process proceeds to step S211. The process from step S211 to step S216 is exactly the same as in the first embodiment described above (FIG. 7).

On the other hand, if it is confirmed in step S101 that the shooting mode is set, the process proceeds to step S102A.
In step S <b> 102 </ b> A, the signal processing and control unit 11 controls the imaging unit 12, the rear display unit 18, or the eyepiece display unit 19 to sequentially display images based on the image data acquired by the imaging unit 12. Execute the process. At the same time, the normal icon 31 (see FIG. 14) is displayed in a predetermined area of the rear display unit 18. Thereafter, the process proceeds to step S103. The processing in step S103 is the same as that in the first embodiment described above (FIG. 7).

  If it is confirmed in step S103 that special effect filter image processing has not yet been applied, the process proceeds to step S103A.

  In step S103A, the touch / slide determination unit 11c of the signal processing and control unit 11 confirms whether or not a slide operation is performed from the right outside the screen toward the inside of the screen. If the slide operation is confirmed here, the process proceeds to step S103B. If the slide operation is not confirmed, the process proceeds to step S103C.

  In step S103B, the signal processing and control unit 11 controls the rear display unit 18 and the like to erase the display of the normal icon 31 being displayed on the rear display unit 18 and simultaneously displays the filter icon 21 in a predetermined area. Thereafter, the process proceeds to step S106.

  On the other hand, in step S103C, the signal processing and touch slide determination unit 11c of the control unit 11 checks whether or not a touch operation on the touch panel 17b has been performed. Here, when the touch operation is confirmed, after the touch position is determined, the process proceeds to step S103D. If the touch operation is not confirmed, the process proceeds to step S111. In addition, after the process of step S111, each process of step S112 and S121-S124 is the same as that of the above-mentioned 1st Embodiment (FIG. 7).

  In step S103D, the signal processing and control unit 11 performs control according to the touch position based on the determination result in step S103C described above. That is, the touch operation performed at the time of the process in step S <b> 103 </ b> C described above is a touch operation on the normal icons 31 displayed on the back surface display unit 18. Therefore, in this step S103D, a control process corresponding to a specific icon selected and instructed by the user by a touch operation from among the plurality of normal icons 31 is executed. The normal icon 31 illustrated here is the above-described flash emission setting, macro shooting setting, exposure correction setting, and the like, but details of individual control processing subroutines corresponding to these are not shown, and the general icons in conventional shooting devices are not shown. The description is omitted because it is the same as the general process. Thereafter, the process proceeds to step S111 (hereinafter, similar to the above-described first embodiment, FIG. 7).

Next, in step S106, the signal processing and control unit 11 proceeds to the processing of step S106A when the downward sliding operation of the vertical slide bar display 21b is not confirmed via the touch slide determination unit 11c.
In step S <b> 106 </ b> A, the touch / slide determination unit 11 c of the signal processing and control unit 11 checks whether or not a slide operation is performed from the predetermined area of the rear display unit 18 toward the screen outward direction. If the slide operation is confirmed here, the process proceeds to step S106B. If the slide operation is not confirmed, the process returns to step S106, and the same process is repeated thereafter.

  In step S106B, the signal processing and control unit 11 controls the rear display unit 18 and the like to erase the display of the filter icon 21 being displayed on the rear display unit 18 and simultaneously displays the normal icon 31 in a predetermined area. Thereafter, the process proceeds to step S111. The subsequent processing is the same as in the first embodiment described above.

  As described above, according to the second embodiment of the present invention, it is possible to obtain the same effect as that of the first embodiment. In addition to this, according to the present embodiment, when the photographing operation is performed while observing the live view image using the eyepiece display unit 19, when the special effect filter image processing mode is activated, the rear display unit 18 is displayed. It is used to display the filter icon 21. Accordingly, the touch and slide operation of the filter icon 21 on the rear display unit 18 can be performed without hindrance while looking through the eyepiece display unit 19. At the same time, since the filter icon 21 is not displayed on the finder image (live view image) of the eyepiece display unit 19, it is possible to concentrate on determining the composition while observing the finder image of the eyepiece display unit 19 without any trouble. it can.

  Further, the touch / slide operation by the user's right thumb 120Rb is constantly monitored by the touch slide determination unit 11c, and a specific slide by the user's right thumb 120Rb in a predetermined area (area indicated by symbol A) of the rear display unit 18 is monitored. Control is performed to display the filter icon 21 or the normal icon 31 when the operation is determined.

  Thereby, when the photographing operation is executed using only the rear display unit 18 (including the first embodiment described above), when the special effect filter image processing mode is activated, the filter icon 21 of the rear display unit 18 is displayed. Since the non-display state can be appropriately set, it is possible to determine the composition while observing the rear display unit 18 without any trouble.

  In the first and second embodiments described above, the icon ring display 21c of the filter icon 21 is used as an operation unit for adjusting the density or strength of the filter effect. However, the present invention is not limited to this. You may use as an operation part for switching a kind. In this case, the operation of adjusting the density or strength of the filter effect may be performed by using another operation member, or setting a desired setting value as a fixed value in advance on the menu setting screen. . As another means, an adjustment slide bar type operation icon or the like for adjusting the density or strength of the filter effect is displayed in a predetermined area of the display unit 18, for example, near the lower edge of the screen, etc. There is also a means of performing touch and slide operations.

[Modification]
In addition to using the icon ring display 21c and the like as the operation unit means for switching the filter effect type, the following modifications can be considered.
17 to 19 are diagrams illustrating modifications regarding the filter icon in the photographing apparatus 10A of the present embodiment. Of these, FIGS. 17 and 18 are diagrams showing a state where the filter icon switching operation is being performed. FIG. 17 shows a state in which the first filter icon “Art1” is displayed, and FIG. A state in which the state is switched from the state to the second filter icon “Art2” by a touch and slide operation is shown.

  An imaging device 10A to which the present modification is applied has a configuration substantially similar to that of the second embodiment described above. Therefore, the same reference numerals are given to the same configurations, the description thereof is omitted, and only different portions will be described in detail below.

  In the photographing apparatus 10A to which this modification is applied, when the special effect filter image processing mode is activated by the means described in the second embodiment, the filter icon 21 is displayed on the rear display unit 18. It is the same. In the state shown in FIG. 17, it is assumed that the first filter icon “Art1” 21A is displayed.

  Further, in this modification, in this state, in the vicinity of the filter icon 21 in the display screen of the rear display unit 18, for example, a predetermined range within a range where the touch and slide operation can be performed with the right thumb 120Rb. The difference is that the slide guide display icon 22 is displayed at the site (see FIG. 17).

  In the state shown in FIG. 17, the user performs a sliding operation in the direction of arrow D in FIG. 17 along the slide guide display icon 22 with the right thumb 120Rb in a touched state on the touch panel 17b, for example. Then, in response to this operation, the currently displayed first filter icon “Art1” 21A is moved and displayed in the direction of arrow D in FIG. The movement of the filter icon 21A at this time is set so as to coincide with the locus traced when the virtual disk 23 shown virtually in FIG. 17 rotates in the direction of the arrow R around the rotation axis center B of FIG. . Then, as shown in FIG. 18, the second type of second filter icon “Art2” 21 </ b> B is displayed at a predetermined position on the rear display unit 18. In this way, by switching the filter icon 21A to the display of the filter icon 21B, it is possible to switch to the desired filter type to be set.

  That is, in this modification, a large number of icons representing a plurality of filter types are prepared, and the icons representing the plurality of filter types are switched one after another by performing the touch and slide operation described above, and the rear display unit 18. Are displayed in a predetermined area. For example, as shown in FIGS. 17 and 18, such display switching is an image similar to the case where the virtual disk 23 is rotated in the direction of the arrow R around the rotation axis center B shown in the drawing. Therefore, if the operation is performed in the same manner thereafter, the special effect filter type switching setting can be easily and intuitively performed only by the touch & slide operation of the touch panel 17b.

  When the above-described filter type switching operation is performed, a display form in which the display of the currently displayed filter icon 21 gradually and continuously moves and the above-described virtual disk 23 rotates. Is natural. And by such a display, a plurality of filter icons (21A, 21B, 21C, 21D...) Arranged side by side on the circumference of the virtual disk 23 move according to the rotation of the virtual disk 23, and the rear surface The display form is such that it sequentially appears in a predetermined area of the display unit 18.

  An apparatus control main sequence of the imaging apparatus 10A to which the present modification configured as described above is applied will be described. FIG. 19 is a flowchart of a device control main sequence according to this modification. Note that the device control main sequence of this modification is substantially the same as the main sequence (FIG. 16) of the second embodiment described above. Accordingly, in the following description, the same processing steps in the above-described first and second embodiments are denoted by the same step numbers and description thereof is omitted, and only different processing steps are described in detail below.

In step S106 of FIG. 19, the signal processing and control unit 11 confirms the slide operation below the upper and lower slide bar display 21b via the touch slide determination unit 11c, and if the confirmation is not performed, the step is performed. The process proceeds to S106C.
In step S <b> 106 </ b> C, the signal processing and touch slide determination unit 11 c of the control unit 11 confirms a slide operation of a predetermined area on the rear display unit 18. That is, any one of the touch operation on the upper part of the slide guide display icon 22 and the subsequent downward rotation slide operation or the touch operation on the lower part of the slide guide display icon 22 and the subsequent upward rotation slide operation. Check whether a series of operations has been performed. Here, if any of the above touch & slide operations is confirmed, the process proceeds to step S106D. If any one of the touch and slide operations is not confirmed, the process proceeds to step S108. The subsequent processing is the same as in the second embodiment (FIG. 16) described above.

  On the other hand, in step S106D, the signal processing and control unit 11 controls the rear display unit 18 and the like to switch the display of the filter icon 21 to the rear display unit 18. When the display of the filter icon 21 on the rear display unit 18 is confirmed, special effect filter image processing corresponding to the set filter icon 21 is executed. Thereafter, the process proceeds to step S111. The subsequent processing is the same as in the second embodiment (FIG. 16) described above.

[Third Embodiment]
Next, a photographing apparatus according to a third embodiment of the present invention will be described below with reference to FIGS. FIG. 20 is a conceptual diagram showing a schematic configuration of a photographing apparatus according to the third embodiment of the present invention.

  The basic configuration of this embodiment is substantially the same as that of the first and second embodiments described above. That is, in the photographing apparatus 10B of the present embodiment, the rear display unit 18 (not shown in FIG. 20, FIG. 21, FIG. 20) corresponding to the display unit 18 in the first and second embodiments described above as a display system configuration block. 22), and an eyepiece display unit 20 (FIG. 20 and the like) having a detachable finder configuration that can be mounted using the accessory shoe 25, and the photographic lens can be replaced. Different points.

  The eyepiece display unit 20 is a so-called electronic viewfinder (EVF) similar to the eyepiece display unit 19 in the second embodiment described above. However, unlike the eyepiece display unit 19, the eyepiece display unit 20 is detachable from the photographing apparatus 10B. It is different in the configuration. In this case, the eyepiece display unit 20 is configured to be attachable to and detachable from the accessory shoe 25 provided on the upper surface of the photographing apparatus 10B. Other functions are substantially the same as those of the eyepiece display unit 19. The eyepiece display unit 20 also operates alternatively with the rear display unit 18.

  In addition, the photographing apparatus 10B of the present embodiment is configured such that a plurality of photographing lenses 12Ba and 12Baa of different types can be alternatively replaced. The photographing lenses 12Ba, 12Baa and the like that can be used by being mounted on the photographing apparatus 10B of the present embodiment are specific information of each lens, specifically, for example, lens configuration information, minimum aperture information, open aperture value information, aberration information. In addition to general lens information such as the above, there is a lens information storage memory for storing icon data such as a lens icon 21E described later (not shown; corresponding to the lens information storage unit 12d in FIG. 1). Other configurations are substantially the same as those of the first and second embodiments described above. Therefore, those constituent members are denoted by the same reference numerals, and detailed description thereof is omitted.

The operation when using the imaging apparatus 10B of the present embodiment configured as described above will be described below with reference to FIGS.
FIG. 21 is a diagram showing a state when viewed from the back side of the photographing apparatus when the photographing apparatus of the present embodiment is held in hand (corresponding to FIG. 3 of the first embodiment). FIG. 22 is a diagram showing that the filter icon is operated in the state of FIG. 21 (corresponding to FIG. 5 of the first embodiment). FIG. 23 is a main flowchart of device control of the photographing device of the present embodiment.

  In the imaging apparatus 10B of the present embodiment, when the apparatus is activated with the power turned on, icon data is read from the lens information storage memory of the mounted imaging lens (12Ba, 12Baa, etc.), and the lens icon 21E is displayed on the rear display unit. 18 and the eyepiece display unit 20 are displayed on predetermined portions, for example, portions within a range that can be operated with the thumb 120Rb of the user's right hand 120R (see FIG. 21).

  Next, in the state of FIG. 21, when the user performs a touch operation on the lens icon 21E of the rear display unit 18 using the thumb 120Rb of the right hand 120R, for example, the filter icon 21Ex appears as shown in FIG. The special effect filter image processing mode is activated. If a slide operation (in the direction of the arrow X in FIG. 22) is continuously performed from this state, special effect filter image processing is applied.

  Next, a device control main sequence (FIG. 23) of the photographing device 10B of the present embodiment will be described below. The device control main sequence of this embodiment is substantially the same as the main sequence (FIG. 16) of the second embodiment described above. Accordingly, in the following description, the same processing steps in the above-described first and second embodiments are denoted by the same step numbers and description thereof is omitted, and only different processing steps are described in detail below.

  In step S101 of FIG. 23, it is confirmed that the photographing apparatus 10B is activated in the photographing mode, and the process proceeds to step S101A.

  In step S101A, the signal processing and control unit 11 confirms whether or not lens replacement has been performed. If it is confirmed that the lens has been replaced, the process proceeds to step S101B. If the lens has not been exchanged, the lens information already held is used and the process proceeds to step S102A.

  In step S101B, the signal processing and control unit 11 communicates with the control unit of the photographic lens that is mounted, reads icon data from the lens information storage memory on the photographic lens side, and stores the internal data on the photographic device 10B side (invalid Temporarily stored in the figure). Thereafter, the process proceeds to step S102A.

  When the slide operation from the right outside the screen to the inside of the screen is confirmed in the process of step S103A, the process proceeds to step S103B. In this step S103B, the signal processing and display control unit 11a of the control unit 11 is performed. Displays the lens icon 21E based on the icon data read from the photographing lens side and temporarily stored in the above-described step S101B on predetermined parts of the rear display unit 18 and the eyepiece display unit 20. Thereafter, the process proceeds to step S106.

  In step S106, the signal processing and control unit 11 confirms whether or not a slide operation to the lower side of the lens icon 21E has been performed via the touch slide determination unit 11c. Here, when the downward sliding operation of the lens icon 21E is not confirmed, the process proceeds to step S106A. The subsequent processing is the same as in the second embodiment (FIG. 16).

On the other hand, when the downward sliding operation of the lens icon 21E is confirmed, the process proceeds to step S107A.
In step S107A, the signal processing and control unit 11 displays the filter icon 21Ex via the display control unit 11a. At the same time, special effect filter image processing is applied. Thereafter, the process proceeds to step S108A.

  In step S108A, the signal processing and control unit 11 monitors the operation determination unit 15 to confirm whether or not the rotation operation of the lens ring 12c has been performed. This operation is an operation for adjusting the density or strength of the filter effect. Here, when the rotation operation of the lens ring 12c is confirmed, the process proceeds to the next step S109. If the rotation operation of the lens ring 12c is not confirmed, it is determined that the settings of the filter effect density or strength adjustment have already been determined, and the process proceeds to step S111. The subsequent processing is the same as in the second embodiment (FIG. 16).

  On the other hand, when it is confirmed that the special effect filter image processing has already been applied in the process of step S103 and the process proceeds to step S104, a slide operation upward of the lens icon 21E is performed in step S104. If not confirmed, the process proceeds to step S108A described above. On the other hand, if the upward sliding operation of the lens icon 21E is confirmed, the process proceeds to step S105A.

  In step S105A, the display control unit 11a of the signal processing and control unit 11 deletes the display of the lens icon 21E. At the same time, the special effect filter image processing already set for the live view image being displayed on the rear display unit 18 or the eyepiece display unit 20 is canceled. Thereafter, the process proceeds to step S111. The subsequent processing is the same as in the second embodiment (FIG. 16).

  As described above, according to the third embodiment, in addition to being able to obtain substantially the same effect as the first and second embodiments described above, according to the present embodiment, the photographic lens can be obtained. As a result of the replacement, the lens icon 21E corresponding to the photographic lens mounted can be displayed. Each time the photographic lens is replaced, a different type of lens icon 21E is displayed, so that the effect of lens replacement can be clearly shown to reassure the user and entertain the user.

  When the special effect filter image processing mode is activated, an optical filter is arranged at the front portion of the photographic lens, and the front side of the lens icon 21E corresponding to the photographic lens mounted on the back display unit 18 is displayed. Since the operation system is such that a pseudo operation for placing the filter icon 21E at the site is performed via the touch panel 17b, the user may perform an intuitive operation when performing a desired operation. Therefore, it can contribute to the improvement of operability. In addition, since the camera can be operated with the camera firmly held, it is possible to concentrate on photographing, and at the same time, it is possible to suppress camera shake and the like, and it is possible to perform quick operation and confirmation.

  Each processing sequence described in each of the above-described embodiments can allow a procedure to be changed as long as it does not contradict its nature. Therefore, for each of the above-described processing sequences, for example, the order of the processing steps is changed each time the processing order is changed, the processing steps are executed simultaneously, or a series of processing sequences are executed. It may be.
