Description

  The present invention relates to an image display device, an image display method, and an image display program suitable as a viewfinder of an imaging device.

  In recent years, portable devices with a photographing function (photographing devices) such as digital cameras have become widespread. Some types of photographing apparatuses have a display unit and a function of displaying a photographed image. Some display screens display a menu screen to facilitate operation of the photographing device. At the time of shooting, the user can perform shooting and observation operations while confirming the through image displayed on the display unit. Such a display unit is often provided on the back surface of the mobile device body, and the user can also perform a shooting operation while confirming a through image displayed on the display unit on the back side during shooting.

  Further, in a photographing device, for example, a viewfinder (eyepiece) may be provided on the upper surface of the photographing device main body. In a single-lens digital camera, a digital video camera, and the like, a viewfinder is provided in order to check the composition of an image and the timing of shooting, and there are many users who take pictures while looking through the viewfinder. In particular, when the surroundings are bright and the visibility of the display unit on the back surface is deteriorated, photographing through the viewfinder is effective. Also, when taking a picture while supporting the camera in a stable posture, particularly when a large lens is attached, it is often advantageous to take a picture while looking through the viewfinder.

  By the way, there is a case where it is desired to perform photographing on a captured image by performing predetermined effect processing such as change in hue and adjustment of brightness. Normally, an image after such effect processing can be displayed on the rear liquid crystal panel, and the user can confirm an image on which a predetermined effect has been applied by a through image.

  In Patent Document 1, when the live view display mode is a display mode for simulating exposure of a still image, there is a technique for notifying the user that the exposure cannot be simulated due to the limitation of the exposure correction amount. It is disclosed.

  However, on the rear liquid crystal panel, live view display may be difficult to see depending on the light condition, and there are also users who want to take a picture without taking their eyes off the viewfinder. In consideration of such a case, it is better to use an electronic viewfinder (hereinafter also referred to as EVF) using an LCD or the like as a viewfinder, and an image subjected to predetermined effect processing by the EVF is confirmed by live view display. It is possible. However, there are users who want to confirm an image to be captured by an optical viewfinder (hereinafter also referred to as OVF) that directly looks at an optical image of a subject incident through a lens. For users adopting such an OVF, even when shooting with predetermined effect processing, the image effect by the predetermined effect processing is confirmed before shooting unless the eye is transferred from the viewfinder to the rear liquid crystal panel. I can't do it. For example, for a user who wants to check an image immediately before shooting with a viewfinder, considering the shutter chance, the user cannot move his eyes from the viewfinder to the rear liquid crystal panel. It was difficult.

  The present invention makes it possible to display a captured image on which a predetermined effect process has been performed and a captured image prioritizing visibility on the same screen, and improve operability for capturing a desired image by the user.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(First embodiment)
FIG. 1 is a block diagram showing a photographing apparatus in which an image display device according to a first embodiment of the present invention is incorporated.

  In the present embodiment, an image (hereinafter referred to simply as “effect processed image”) that has been subjected to predetermined effect processing (hereinafter simply referred to as “image effect processing”) such as a special effect that imparts an image effect to a captured image and a subject are viewed with the naked eye. The image obtained by performing image processing (hereinafter referred to as visibility priority image processing) that enables the same image display as when the image is output on the output of the image sensor (hereinafter referred to as visibility priority image) is the same In addition to enabling display on the display screen, the display of the effect processing image and the visibility priority image is controlled in accordance with a user operation. Thus, the user can take an image while capturing the subject with the same visibility as when the OVF is used while confirming the image effect when the image effect processing is performed.

  Note that the image effect processing for obtaining an effect processing image is image processing when creating a work-like, report-like or explanatory picture according to the user's subjectivity by changing the color, contrast, brightness, image graininess, etc. . The effect-processed image may have poor visibility because it changes color and description when viewed with the naked eye. In addition, exposure and the like can be used as a reference for shooting if they are quantified and displayed, but it is easier to understand the colors and descriptions by visual inspection. Observation by EVF is preferable because it is affected by external light.

  Visibility priority image processing is image processing that matches the color and brightness of a subject when viewed with a camera and the direct viewing with the naked eye according to the state of viewing with the eye. For example, HDR processing, frame rate, etc. are matched to how the naked eye can be seen. When it is dark, you may perform processing to make it appear bright so that you can see the subject, but basically it is processing to make the image the same as when looking through the optical viewfinder. When shooting with EVF, it is possible to focus and shoot while chasing the subject. Therefore, by displaying the visibility priority image with EVF, shooting operability can be improved. Note that it may be preferable to display a visibility priority image immediately before shooting in order to confirm the facial expression, posture, and composition of the subject. Depending on the situation, priority may be given to increasing the frame rate without performing heavy image processing on the control unit. Since the effect processing is also in the direction in which the image processing time increases due to the load on the control unit (because the frame rate decreases), if the image cannot catch up due to the movement of the subject or the panning operation of the photographer, the processing time in normal image processing Priority is given to visibility by raising the frame rate. That is, depending on the situation and the subject, the concept of visibility may be changed by applying speed priority processing, natural image processing, or the like. Although an example of improving the visibility by increasing the frame rate with light image processing has been shown, conversely, it is also possible to improve the visibility of dark scenes by reducing the frame rate (over the imaging time) This is an improvement (priority) process. An image display that is naturally observable so that a human can see and grasp the situation is called visibility priority processing. That is, visibility is given priority to images other than when the user intentionally gives an image effect and selects image processing that cannot be expressed as it is (effect processing). Depending on the situation, the effect of visibility may be changed, or the user may select so that the object can be confirmed well. Visibility has priority, generally the frame rate is fast, and images that have been processed so that the image on the display device looks the same as when there is no display device use the device. It can be said that there is no difference or uncomfortable feeling when observed without using the device. In particular, if the color or the like is emphasized too much, the consistency with the direct viewing is lost and it is easy to lose sight.

  2A and 2B are explanatory diagrams for explaining the effect processing image. The effect processing images 21 and 22 shown in FIGS. 2A and 2B are images obtained by performing different predetermined image effect processing on a single captured image captured for the same subject. The effect processed image 21 includes an image portion 21a having a relatively dark background, an image portion 21b having a relatively bright background such as a cloud, and an image portion 21c of a person. The effect processed image 22 includes an image portion 22a having a relatively dark background, an image portion 22b having a relatively bright background such as a cloud, and an image portion 22c of a person.

  In FIG. 2A and FIG. 2B, as a result of performing different image processing on the image portions 21 c and 22 c on the image portions 21 b and 22 b by hatching, for example, color images And brightness are different from each other.

  FIG. 3 is an explanatory diagram for explaining the visibility priority image. FIG. 3 shows the visibility priority image 23 obtained by performing the visibility priority image processing on the captured image before the processing of the effect processing images of FIGS. 2A and 2B. The visibility priority image 23 is obtained by performing, for example, HDR processing on the captured image. The visibility priority image 23 includes a relatively dark background image portion 23a, a relatively bright background image portion 23b such as a cloud, and a human image portion 23c. The image portions 23a to 23c are hatched to indicate that the image portions have a higher dynamic range than the image portions 21a to 21c and 22a to 22c in FIGS. 2A and 2B. The visibility priority image 23 is not subjected to processing such as color adjustment on the captured image, but is subjected to processing in which only the dynamic range is expanded by HDR processing, and is similar to the image display obtained by OVF. Is realized by EVF. Thereby, each image part 23a-23c of the visibility priority image 23 is excellent in visibility similarly to the case where the subject is observed with the naked eye.

  In FIG. 1, the imaging device 10 is provided with an imaging unit 12 on the front surface. The imaging unit 12 includes an imaging element (not shown) configured by an imaging element such as a CCD or a CMOS sensor. Further, the imaging unit 12 includes a lens unit (not shown) that guides the subject optical image to the imaging element. The lens unit includes a lens (not shown) for zooming and focusing. These lenses are driven and controlled by the imaging control unit 11a of the control unit 11. In the imaging unit 12, the focus position, the zoom position, the aperture, and the like are controlled by the imaging control unit 11a. The image sensor photoelectrically converts a subject optical image from the lens unit to obtain a captured image.

  For example, the control unit 11 may be configured by a processor such as a CPU (not shown) and perform camera control according to a program stored in the memory. The imaging control unit 11a outputs a drive signal of the imaging element to the imaging unit 12 to control the shutter speed, the exposure time, and the like, and reads a captured image from the imaging unit 12. The control unit 11 as an image acquisition unit performs predetermined signal processing, for example, color adjustment processing, matrix conversion processing, noise removal processing, and other various signal processing on the read captured image.

  4A and 4B are explanatory views showing the appearance of the photographing apparatus 10. FIG. As shown in FIG. 4A, the housing 10a of the photographing apparatus 10 has a lens barrel 12a on the front surface and a finder portion 18a on the top surface. The lens unit of the imaging unit 12 is housed in the lens barrel 12a. A shutter button 32 and two dial operation parts 33a and 33b are disposed on the upper surface of the housing 10a. The user holds the lens barrel 12a toward the subject while holding the case 10a with the left and right hands 35 and 36, for example, with the finger of the left hand 35 sandwiching the ring operation unit 31.

  Note that the user can not only press the shutter button 32 with the index finger 36b while looking into the viewfinder 18a, for example, while holding the photographing device 10, but also the thumb 36a of the right hand as shown in FIG. 4B. The dial operation unit 33a can be easily operated, and the dial operation unit 33b can be easily operated by the index finger 36b.

  In FIG. 1, the operation unit 13 includes a ring operation unit 31, a shutter button 32, dial operation units 33a and 33b, function buttons (not shown), various switches for shooting mode setting, and the like. An operation determination unit 11e in the control unit 11 receives an operation signal based on a user operation from the operation unit 13 and determines the content of the user operation. The control unit 11 controls each unit based on the operation determination result.

  The control unit 11 can perform processing related to recording and reproduction of captured images. For example, the control unit 11 can compress the captured image after signal processing, and can apply the compressed image to the recording unit 15 for recording. As the recording unit 15, for example, a card interface can be adopted, and the recording unit 15 can record image information, audio information, and the like on a recording medium such as a memory card.

  In addition, the photographing device 10 is provided with a clock unit 14. The clock unit 14 generates time information and outputs it to the control unit 11. As a timekeeping unit, it is used for measuring the exposure time, measuring the “predetermined period after the end of operation” described later, and the like.

  The display control unit 11b of the control unit 11 executes various processes related to display. The display control unit 11b can give the captured image after the signal processing to the display unit 17 and the finder display unit (F display unit) 18 provided on the back surface. The display parts 17 and 18 have display screens, such as LCD, and display the image given from the display control part 11b. In addition, the display control unit 11b can display various menu displays on the display screens of the display units 17 and 18.

  The control unit 11 can read the captured image recorded in the recording unit 15 and perform expansion processing. The display control unit 11b can reproduce the recorded image by giving the expanded captured image to the display units 17 and 18.

  For example, the display unit 17 provided on the back surface of the housing 10a has a display screen 17a for displaying a captured image, as will be described later. A touch panel 17b is provided on the display screen 17a. The touch panel 17b can generate an operation signal corresponding to the position on the display screen 17a pointed to by the user with a finger. This operation signal is supplied to the control unit 11. Thereby, when the user touches or slides on the display screen 17a, the operation determination unit 11e of the control unit 11 performs the user's touch position, the operation of closing and separating the finger (pinch operation), the slide operation, Various operations such as a position reached by a slide operation, a slide direction, and a touch period can be detected. Thereby, the control part 11 can perform the process corresponding to a user's touch panel operation.

  As shown in FIG. 4B, the rear display unit 17 is disposed so as to occupy substantially the entire rear surface of the housing 10 a of the photographing apparatus 10, and the photographer can display the rear display unit 17 during photographing. The through image displayed on the display screen 17a can be confirmed, and the photographing operation can be performed while confirming the through image.

  As shown in FIG. 4B, the F display unit 18 is housed in a finder unit 18a provided on the upper surface of the housing 10a. An eye sensor 19 is provided in the vicinity of the finder unit 18a. The eye sensor 19 detects that the user has brought his eye close to the finder unit 18a, and outputs the detection result to the control unit 11. The display control unit 11b may be configured to switch the image output destination between the display unit 17 on the back and the F display unit 18 according to the detection result of the eye sensor 19.

  The control unit 11 is provided with an image effect processing unit 11d. The image effect processing unit 11d as the second image processing unit can perform predetermined image effect processing on the captured image. For example, the image effect processing unit 11d can perform predetermined effect processing for changing the color, contrast, brightness, graininess, and the like of the captured image. The control unit 11 not only gives and records the captured image subjected to the image effect processing to the recording unit 15, but also gives the captured image after the image effect processing to the display control unit 11 b for display as a through image. Can be done.

  In the present embodiment, the control unit 11 is provided with a visibility priority processing unit 11c. The visibility priority processing unit 11c as the first image processing unit can perform visibility priority image processing on a captured image. For example, the visibility priority processing unit 11c can generate a visibility priority image with a high dynamic range by HDR synthesis processing for a plurality of images shot at different exposures. The control unit 11 can give and display the visibility priority image as a through image to the display control unit 11b.

  In the present embodiment, the imaging control unit 11a controls the visibility priority processing unit 11c, the image effect processing unit 11d, and the display control unit 11b on the basis of the operation determination result of the operation determination unit 11e, thereby visually recognizing. The display destination, display timing, and display method of the sex priority image and the effect processing image can be changed. For example, the imaging control unit 11 a may display the visibility priority image on the F display unit 18 and display the effect processing image on the display unit 17. In addition, the imaging control unit 11a controls the display control unit 11b to display the visibility priority image during normal operation, and an operation period for image effect processing or from the start of this operation to a predetermined period after the operation ends. You may make it display an effect process image in a period (henceforth an effect process image display period). In addition, the imaging control unit 11a may switch and display the visibility priority image and the effect processing image between the normal time and the effect processing image display period, and display the visibility priority image at the normal time. In the effect processing image display period, both the visibility priority image and the effect processing image may be displayed. For example, the effect processing image may be displayed on the small screen in the visibility priority image.

  Note that the shooting control unit 11a may end the effect processing image display period at a time before an operation for shooting by the user is performed. Specifically, when the shutter button is pressed halfway (operation for shifting to shooting) or when an effect processing image is displayed on the display unit 17, when looking through the viewfinder (when the eye sensor reacts), That is, the effect process display may be terminated in accordance with the operation for shifting to shooting.

  Next, the operation of the embodiment configured as described above will be described with reference to FIGS. FIG. 5 is a flowchart showing camera control, and FIG. 6 is an explanatory diagram showing an example of image display in the effect processing image display period.

  In step S1, the shooting control unit 11a of the control unit 11 determines whether or not a shooting mode for performing image effect processing (hereinafter referred to as an effect processing shooting mode) is designated. If the effect processing shooting mode is not specified, the shooting control unit 11a shifts the processing to step S2 and determines whether another shooting mode is specified. If another shooting mode is designated, the shooting control unit 11a moves the process to step S3 and executes another shooting mode.

  If the control unit 11 determines in step S2 that no other shooting mode is designated, the control unit 11 proceeds to step S5 and determines whether or not reproduction is instructed. If reproduction is instructed, the control unit 11 reproduces an image in step S6. When the user instructs to change the reproduction image, the control unit 11 shifts the process from step S7 to step S8 and changes the image. If the playback mode is not designated in step S5, the control unit 11 shifts to a mode for acquiring an image file in step S9.

  If the shooting control unit 11a determines that the effect processing shooting mode is designated in step S1, the shooting control unit 11a controls the image effect processing unit 11d in step S11 under the conditions set for the captured image. Apply image effect processing. The image effect processing unit 11d gives the effect processing image subjected to the image effect processing to the display control unit 11b, and the display control unit 11b outputs the effect processing image to the display unit 17 and the F display unit 18.

  In step S12, the imaging control unit 11a checks whether or not the user is in contact with the finder unit 18a based on the output of the eye sensor 19. The imaging control unit 11a turns off the display of the display unit 17 in step S13 when the user is in contact with the viewfinder unit 18a, and turns off the display of the F display unit 18 in step S21 when the user is not in contact with the eyepiece. To do.

  When the user is in contact with the finder unit 18a, the imaging control unit 11a determines whether or not the visibility priority mode for displaying the visibility priority image is specified in step S14. If the visibility priority mode is not designated, the imaging control unit 11a controls the display control unit 11b to display the effect processing image from the image effect processing unit 11d on the F display unit 18 in step S15. . If the visibility priority mode is designated, the imaging control unit 11a controls the visibility priority processing unit 11c in step S16 to execute the visibility priority image processing on the captured image.

  The visibility priority processing unit 11c obtains a visibility priority image with an expanded dynamic range by, for example, HDR synthesis processing of a plurality of captured images that have been captured a plurality of times while changing the exposure. The visibility priority image obtained by the visibility priority processing unit 11c enables image display with a wide dynamic range similar to the image display by OVF when the subject is observed with the naked eye. The imaging control unit 11 a controls the display control unit 11 b to display the visibility priority image on the F display unit 18.

  The user can see the visibility priority image displayed on the display screen of the F display unit 18 by looking into the finder unit 18a. That is, the user can perform a shooting operation while viewing an image approximate to the image displayed on the OVF on the EVF display screen.

  Here, it is assumed that the user performs an operation for changing the setting of the image effect processing, that is, an operation for changing the type and intensity of the image effect. For example, when the image effect process is to change the graininess of the image, an operation to change the size of the grain that gives the graininess is performed. For example, by using the dial operation units 33a and 33b, the user can perform various operations such as an operation for changing the setting of the image effect processing without taking his eyes off the finder unit 18a. The imaging control unit 11a determines whether or not an operation for changing the setting of the image effect processing is performed in step S17.

  In the present embodiment, when the setting operation of the image effect processing is performed, the imaging control unit 11a sets at least the setting operation period to the effect processing image display period, and corresponds to the image effect processing during this period. The effect processed image is displayed on the F display unit 18. In the example of FIG. 5, in step S18, the display control unit 11b displays a guide display capable of confirming the effect processing image in addition to the visibility priority image. The guide display is not limited to the sub-screen shown in FIG. 6, and the effect processing image may be displayed on the entire surface only during the operation (the effect can be confirmed more easily). In addition, display of a GUI for setting as described in FIG. 9 is also included.

  FIG. 6 shows an image displayed in this case. In the effect processing image display period, for example, an image 51 shown in FIG. 6 is displayed on the display screen of the F display unit 18. The image 51 corresponds to the visibility priority image 23 of FIG. 3 and includes image portions 51a, 51b, and 51c having excellent visibility. Further, a guide display 41a is displayed on the image 51. The guide display 41a displays an effect processing image obtained by the image effect processing on a small screen. When the user performs an operation for changing the setting of the image effect processing, the effect processing image changes, and the image in the guide display 41a also changes.

  The user can confirm the image obtained by the current image effect processing by the guide display 41 a displayed on the display screen of the F display unit 18. In other words, in the present embodiment, the F display unit 18 can display the same priority image for visibility as when OVF is used, and can display the effect processing image reflecting the image effect processing. Even when OVF is used, it is possible to display setting values (image parameters) set in image effect processing by character display or the like. However, it may be difficult to confirm the image effect with numerical values. For example, although it may be possible to predict the effect of image effect processing by quantification of exposure, etc., even if the color is quantified, generally the color given by the image effect processing is recognized. Is extremely difficult. In the present embodiment, the subject to be photographed can be confirmed with good visibility by the visibility priority image, and image effects such as color, brightness, and graininess by various image effect processing can be obtained by the effect processing image. It is possible to confirm the image, and the user can take a desired image relatively easily.

  When the setting operation is finished and the effect processing image display period elapses, the imaging control unit 11a turns off the guide display in step S19. Accordingly, the user can confirm the subject with good visibility by the visibility priority image on the F display unit 18 at the timing immediately before the photographing operation, for example.

  In the example of FIGS. 5 and 6, the example in which both the visibility priority image and the effect processing image are displayed in the effect processing image display period has been described, but only the effect processing image is displayed instead of the visibility priority image. You may make it do.

  If the user does not have an eye on the finder unit 18a, the imaging control unit 11a shifts the processing from step S12 to step S21 to turn off the F display unit 18, and in step S22, the display unit that is a rear panel. 17 displays an effect processing image reflecting the setting operation of the image effect processing.

  FIG. 4B shows a state in which the effect processing image 41 is displayed on the display screen 17a of the display unit 17 which is a rear panel. The effect processed image 41 is an effect processed image corresponding to FIGS. 2A and 2B and includes image portions 41a to 41c. Further, the image 41 also has a display 43 for changing image effect processing settings. For example, the setting is changed when the user touches the left and right arrows on the display 43, and the setting can be reflected by touching the center frame.

  In step S23, the imaging control unit 11a determines whether an imaging operation by the user has been performed. When a shooting operation is performed, the shooting control unit 11a causes the recording unit 15 to record an image acquired by shooting.

  In the example of FIGS. 5 and 6, the example in which the visibility priority image is displayed only on the F display unit 18 and only the effect processing image is displayed on the display unit 17 has been described. You may make it display a priority image and an effect process image.

  As described above, in the present embodiment, it is possible to display not only a captured image that has been subjected to a predetermined effect process but also a captured image that prioritizes visibility on the same screen. For example, by displaying the visibility priority image on the finder display unit of the finder unit, the user can perform a shooting operation while confirming the subject with a feeling close to that when observing the subject with the naked eye. In addition, when image effect processing is performed on a captured image, an effect processing image reflecting image processing can be confirmed on the display screen of the F display unit in an effect processing image display period based on the setting operation. The user can perform the setting operation while confirming the image effect without taking his eyes off the viewfinder. Thereby, the operativity for performing the imaging | photography which provided the image effect process which a user desires can be improved significantly.

(Second Embodiment)

The circuit configuration in this embodiment is the same as that of the first embodiment in FIG. 8A and 8B are perspective views showing an example of the appearance of a photographing apparatus in which the image display apparatus according to this embodiment is incorporated.

  Conventionally, photographing using a lens filter such as a color filter or a polarization filter may be performed. The present embodiment is an example in which an image obtained by special effect shooting using such a filter is applied to a shooting device that realizes image processing.

  First, with reference to FIG. 8A and FIG. 8B, the schematic structure of the external appearance of the imaging device will be described. As shown in FIGS. 8A and 8B, the photographing apparatus 61 includes various electrical boards such as a main board on which a control circuit and the like are mounted in a housing 62, a power board on which a power circuit including a battery and the like are mounted. Are housed, and a circuit similar to FIG. 1 is formed on these electric boards.

  A lens barrel 63 is detachably attached to a lens mount portion (not shown) at a substantially central portion of the front surface 62a of the housing 62. In addition, a display unit 17 (see FIG. 1) is disposed on substantially the entire rear surface 62b of the housing 62, and a touch panel 17b is disposed on the display screen 17a of the display unit 17. Further, a finder portion 64 constituting the F display portion 18 is disposed at a part of the upper end of the back surface 62b.

  In the photographing device 61, various operation units 13 are disposed on the front surface 62a, the back surface 62b, and the upper surface 62c of the housing 62. For example, as the operation unit 13, a power button 71, a shutter button 72, a front dial 73a, a rear dial 73b, and the like are provided on the upper surface 62c. On the rear surface 62b, an INFO button 74, a mode button 75, a PICT button 76, a cross key and OK button 77, a playback button 78, a menu button 79, and the like are provided as the operation unit 13. Further, a picture mode dial 80 is provided as an operation unit 13 on the front surface 62a.

  The front dial 73a, the rear dial 73b, and the picture mode dial 80 are dial-shaped operation members that are pivotally supported with respect to a fixed portion of the housing 62.

  The operations of the operation unit 13 are detected by the operation determination unit 11e. The imaging control unit 11a recognizes the user instruction based on the determination result of the operation determination unit 11e. For example, when the PICT button 76 is operated in the visibility priority mode, the imaging control unit 11a performs an operation for changing the setting of the image effect processing by the user, that is, the image parameter is being set. And the effect processing image display period is set. Further, when the PICT button 76 is operated during the effect processing image display period, the imaging control unit 11a may end the effect processing image display period and display only the visibility priority image.

  Incidentally, a lens filter such as a color filter is mounted on the front surface of the lens. By changing the lens filter to be mounted, the type of special effect shooting can be changed. In the present embodiment, such a change operation of the type of special effect shooting is performed by the picture mode dial 80 provided on the front surface of the camera so that it can be performed in the same manner as when the lens filter is attached. The shooting control unit 11a recognizes the state of the picture mode dial 80 based on the output of the operation determination unit 11e. The imaging control unit 11a can change the type of image effect processing by controlling the image effect processing unit 11d by rotating the picture mode dial 80 in the same manner as when the type of filter is changed. It has become.

  Next, the operation of the embodiment configured as described above will be described. FIG. 9 is a flowchart showing an example of a specific operation flow of live view display in step S34 in FIG. FIG. 9 also shows an example of an image obtained by each process. 10A and 10B are explanatory diagrams for explaining the processing timing of live view display.

  When the power is turned on, the control unit 11 starts operating, and supplies power to each unit in step S31 of FIG. In step S32, the imaging control unit 11a reads out various mode data recorded in the recording unit 15 or a memory (not shown) at the previous power-off and an image parameter for determining the processing of the image effect processing, and sets the mode setting and parameter setting flag. Clear. In step S33, the imaging control unit 11a performs photometry with an imaging unit or a photometric unit (not shown), and performs live view display with appropriate brightness in step S34 using the photometric value. The live view display in step S34 will be described later. The imaging control unit 11a determines whether or not a camera operation has occurred in step S35. If the camera operation has not been performed, the process returns to step S33 to repeat photometry and live view display.

  When a camera operation is performed, the imaging control unit 11a determines whether or not this camera operation is a first-pressing operation of the shutter button 72 (step S36). If it is determined that the shutter button 72 is not operated (OFF), the imaging control unit 11a determines whether or not the operation is an image parameter setting operation in the next step S37.

  For example, when the PICT button 76 is pressed, the imaging control unit 11a determines that an image parameter setting operation and setting cancellation are performed. When the parameter setting operation is performed, the imaging control unit 11a switches the parameter setting flag to a value indicating that the parameter is being set (step S38). That is, in S37, it is determined whether or not the PICT button has been operated, and every time the PICT button is pressed, it is assumed that toggle between [Setting mode] and [Non-setting mode]. , [Clear] ⇒ [Set], [Set] ⇒ [Clear]. In this way, the parameter setting flag is switched / set. The effect processing image display period is set when the parameter setting flag is being set (when the flag is set). The set image parameters are stored in a memory (not shown) or the like to be reflected in the live view display in step S34, and are recorded in the recording unit 15 or a non-volatile memory (not shown) in step S51 described later.

  The imaging control unit 11a determines whether or not a mode change operation has been performed in step S39. When the image effect processing mode is changed, the image effect processing unit 11d changes the image effect processing mode to the designated mode (step S40). In step S41, the imaging control unit 11a determines whether the power switch is on or off, and if it is on, the process returns to step S33.

  If it is determined in step S36 that the first step of the shutter button 72 has been pressed, the imaging control unit 11a moves the process to step S45, and performs autofocus processing (AF) and photometry processing. Next, the imaging control unit 11a clears the parameter setting flag in step S46, and determines whether or not the second stage of the shutter button has been pressed (step S47).

  By clearing the parameter setting flag, the effect processing image display period ends, live view display in step S34 is performed via steps S47 and S33, and the display screen of the F display unit 18 of the finder unit 64 is described later. A visibility priority image is displayed as shown in FIG. In this way, in the state immediately before shooting after the first stage of the shutter button 72 is pressed, the user looks at the live view image based on the visibility priority image having a wide dynamic range, for example, as in the case of observing the subject with the naked eye. Shooting operation can be performed.

  If it is determined in step S47 that the second stage of the shutter button 72 has not been pressed, the imaging control unit 11a returns the process to step S33 to perform live view display as described above. On the other hand, when the second stage of the shutter button 72 is pressed, the imaging control unit 11a performs imaging. The captured image subjected to the image effect processing by the image effect processing unit 11d is given to the recording unit 15 and recorded.

  If the first step of the shutter button 72 is pressed in a very short time after pressing the PICT button 76, the effect processing image display period ends in a short time after the display of the effect processing image, and the user It is conceivable that the effect processing image cannot be sufficiently confirmed. Therefore, in such a case, the effect processing image display period may be continued from the pressing operation of the PICT button 76 until a predetermined time later. In the example of FIG. 7, the effect processing image display period is ended by pressing the first step of the shutter button 72. However, the PICT button 76 is pressed during the effect processing image display period. Thus, the effect processing image display period may be ended.

  If it is determined in step S41 that the power switch is turned off, the imaging control unit 11a records various modes and image parameters including the image effect processing mode in the recording unit 15 or a non-illustrated non-volatile memory in step S51. . In step S52, the control unit 11 stops the supply of power to each unit and ends the process.

(Live view display)
In step S60 of FIG. 9, the imaging control unit 11a determines whether or not the finder display mode is set. If it is determined that the mode is not the finder display mode, the imaging control unit 11a performs live view display on the display unit 17 on the back. That is, in this case, the imaging control unit 11a instructs the imaging unit 12 to perform imaging in step S71. The imaging unit 12 images the subject and outputs the captured image to the control unit 11. In step S72, the image effect processing unit 11d performs image effect processing that reflects image effect parameters based on user operations in the designated image effect processing mode, and generates an effect processed image. This effect processing image is displayed on the display unit 17 by the display control unit 11b (step S73).

  In step S74, the imaging control unit 11a determines whether or not an image parameter for image processing is being set based on the parameter setting flag. The imaging control unit 11a ends the process when the image parameter is not being set. For example, in this case, the effect processing image 131 is displayed on the display screen 17 a of the display unit 17. Further, when the image parameter is being set, the imaging control unit 11a displays a setting GUI 131a such as a color filter selection GUI 83 in FIG. 12A described later on the display screen 17a of the display unit 17 in step S75. For example, in this case, the setting GUI 131 a is displayed on the effect processing image 131 on the display screen 17 a of the display unit 17.

  FIG. 10A shows processing of the control unit 11 in this case. As shown in FIG. 10A, imaging, image processing, and live view display are sequentially repeated.

  If it is determined in step S60 that the finder display mode is set, the imaging control unit 11a proceeds to step S61 and determines whether or not the image parameter is being set by using the parameter setting flag. To do. Also in this embodiment, when the image parameter is not being set, the visibility priority image is displayed, and when the image parameter is being set, the effect processing image is displayed.

That is, if it is determined in step S61 that the image parameter is not being set, the imaging control unit 11a instructs the imaging unit 12 to perform two imaging operations for the HDR composition process in step S62. The imaging unit 12 images the subject twice with different exposures, and outputs two captured images to the control unit 11. In step S65, the visibility priority processing unit 11c generates an image in which the dynamic range is expanded by the HDR synthesis processing using two captured images, that is, the visibility priority image 132. FIG. 10B shows such processing of the control unit 11. As shown in FIG. 10, the two imaging operations, the HDR synthesis process, and the live view display are sequentially repeated.
Note that FIG. 10 is an example, and the dynamic range may be expanded by image processing by one imaging, or a normal live view or a live view with a reduced frame rate in a dark place may be used as described above. . In short, it is only necessary to improve visibility. Further, it is possible to prioritize visibility (priority is to follow the live view to the change and movement of the subject) with a normal live view image that secures the frame rate without performing an effect process with a large load.

  In the example of FIG. 9, not only the visibility priority image 132 but also the reduced image 83 of the effect processing image is displayed on the display screen of the F display unit 18 at the same time. That is, in step S63, the image effect processing unit 11d performs image effect processing that reflects image parameters based on user operations in the image effect processing mode specified for the captured image. Note that, in the imaging for HDR composition in step S62, there is a possibility that shooting is generally performed with overexposure and underexposure and is not performed with proper exposure. Therefore, the image effect processing unit 11d may perform image effect processing after gain-up or gain-down of the captured image in the image effect processing in step S63. The display control unit 11 b converts the effect processed image from the image effect processing unit 11 d into a reduced image and displays the reduced image on the display screen of the F display unit 18. Note that the display of the reduced image 83 is an option and is not necessarily displayed.

  In step S <b> 66, the display control unit 11 b displays the visibility priority image 132 on the display screen of the F display unit 18, and the effect processing image in a partial region (finder auxiliary screen) of the visibility priority image 132. The reduced image 133 based on is displayed. Thus, the user can take a picture while confirming the visibility priority image 132 on the display screen of the F display unit 18.

  Here, it is assumed that the user performs an operation for changing the image parameter of the image effect processing. Then, the process proceeds from step S61 to step S67, and the imaging control unit 11a instructs the imaging unit 12 to perform one imaging. The imaging unit 12 images the subject and outputs the captured image to the control unit 11. In step S68, the image effect processing unit 11d performs image effect processing using the image parameters set by the user in the designated image effect processing mode, and generates an effect processed image. The effect processed image 131 is displayed on the F display unit 18 by the display control unit 11b (step S69). In step S <b> 70, the imaging control unit 11 a displays the setting GUI 131 a on the display screen of the F display unit 18 so as to overlap the effect processing image 131. Also in this case, as shown in FIG. 10A, imaging, image processing, and live view display are sequentially repeated.

In this manner, the visibility priority image is displayed on the F display unit 18 during the period when the image parameter is not set, so that the user can perform a shooting operation while viewing an easy-to-view image with an expanded dynamic range. . Dynamic range expansion is an example that is close to familiar images for those who are used to optical viewfinders and easy to see even in scenes with large brightness differences such as backlit, but as described above, it is limited to expansion of dynamic range In short, the visibility priority image may be an easily viewable image.
Further, during the setting of the image parameter, an image effect process reflecting the image parameter set in the image effect processing unit is performed, and the user's image parameter changing operation is sequentially reflected in the effect processed image and the setting GUI. . As a result, the user can set the image parameter while confirming the change in the image due to his / her setting operation on the F display unit 18. That is, the user can check the subject with an easy-to-see image and the effect of the image effect processing without taking his eyes off the finder unit 64.

  Next, specific examples of image effect processing that can be employed in the present embodiment will be described with reference to the explanatory diagrams of FIGS. 11A to 11E and the flowcharts of FIGS. 12A to 12D. 12A to 12D correspond to FIGS. 11A to 11D, respectively, and show respective processing flows of the image effect processing unit 11d in steps S63, S68, and S72 of FIG. Moreover, in FIG. 11A-FIG. 11E, it shows that the color differs, changing the kind and shade of hatching.

  In the photographing device 61, the image effect processing mode is switched by the picture mode dial 80. In the example of FIGS. 11A to 11E, an example in which five processes are possible as the image effect process is shown. 11A to 11E show examples of the visibility priority image and the effect processing image when different image effect processing is performed on the same subject.

  In the visibility priority mode, when an image parameter setting operation, which is an operation for changing the setting of the effect process, is not performed, a visibility priority image is displayed on the F display unit 18. The left image 81 in FIG. 11A shows the visibility priority image displayed on the F display unit 18 of the finder unit 64. The visibility priority image 81 includes an image portion 85 of a red petal of a tulip, an image portion 86 of a green leaf of a tulip, an image portion 87 of a greenish background such as a plant, and an image portion 88 of a blueish background such as the sky. .

  FIG. 11A shows an example in which the image effect processing mode is a monochrome (monochrome) mode. The images 82a and 82b on the center and right side of FIG. 11A are displayed when the PICT button 76 is pressed with the visibility priority image 81 displayed when the picture mode dial 80 is in the M (monochrome) mode. The effect processing image displayed on the display screen of F display part 18 of the part 64 is shown. In the monochrome mode, an image effect similar to that obtained when a color filter is arranged and monochrome photography is performed is obtained. When the PICT button 76 is pressed in the monochrome mode, the imaging control unit 11a controls the image effect processing unit 11d and the display control unit 11b to display the color filter selection GUI 83 for monochrome imaging.

  In the monochrome mode, an image substantially equivalent to an image obtained by a colored filter attached in front of the lens is obtained by image processing. By turning the front dial 73a, a filter color to be selected from 12 colors is designated. Can do. Further, the intensity (density) of the selected color filter can be selected from, for example, three levels by operating the rear dial 73b.

  In accordance with the user's selection operation, the image effect processing unit 11d acquires the color filter setting information set by the front dial 73a and the rear dial 73b in step S81 of FIG. 12A, and calculates a monochrome coefficient in step S82. In step S83, the image effect processing unit 11d performs standard image processing on the captured image, and then generates a monochrome image using the monochrome coefficient (step S85). In addition, the image effect processing unit 11d controls the display control unit 11b to display the color filter selection GUI 83 according to the user's selection operation. The user can confirm the state of selection of color and intensity by the color filter selection GUI 83. The color filter selection GUI 83 indicates, for example, a color change in the circumferential direction and a strength in the radial direction.

  The shooting control unit 11a outputs an effect processing image based on the subject being imaged for display on the F display unit 18 as a live view image during filter setting (step S85). In the example of FIG. 11A, while the red filter is selected, there is a lot of transmitted light through the red flower portion, and therefore the flower image portion 85a of the effect processing image 82a becomes high in brightness and becomes whitish. Also, the sky (blue) and leaf (green) portions of the background are reduced in brightness and darkened because the amount of light transmitted through the filter is reduced. On the other hand, when the green filter is selected, the flower image portion 85b is black and the sky and leaf image portions are white as in the effect processing image 82b.

  FIG. 11B shows an example in which the image effect processing mode is the color profile mode. When the picture mode dial 80 is in the C (color profile) mode and the PICT button 76 is pressed while the visibility priority image 81 is displayed, the middle and right images 92a and 92b in FIG. The effect processing image displayed on the display screen of F display part 18 of finder part 64 is shown. The color profile mode freely adjusts the color saturation. When the PICT button 76 is pressed in the color profile mode, the imaging control unit 11a controls the image effect processing unit 11d and the display control unit 11b to display the saturation setting GUI 93 for each color for color profile imaging.

  In the color profile mode, for example, each of the twelve colors can be adjusted in 11 steps (saturation up 5 steps, saturation down 5 steps) by the image effect processing unit 11d. For example, the front dial 73a is turned to select a color for adjusting the saturation, and the rear dial 73b can be used to adjust the saturation.

  In step S91 of FIG. 12B, the image effect processing unit 11d performs standard image processing on the captured image. The image effect processing unit 11d substitutes 12 for the variable n for designating the color (step S92), acquires the set value of the color designated by n based on the user operation (step S93), and designates it using the set value. A color correction process for the color COLOR (n) is performed (step S94). The image effect processing unit 11d decrements the variable n (step S95), repeats the processing of steps S93 to S95 until n does not satisfy n> 0, and corrects each color of the captured image. When all 12 colors have been corrected, the imaging control unit 11a shifts the process from step S96 to step S97, and displays an effect processing image based on the subject being imaged on the F display unit 18 as a live view image. Output to.

  The effect processing image 92a in FIG. 11B shows that the saturation of the image portions 95a and 96a of flowers and leaves is finished by reducing the saturation of red and green. Further, the effect processing image 92b of FIG. 11B shows that the saturations of green and blue are increased to express the sky and leaf image portions 95b and 96b vividly. Thus, in the color profile mode, colors can be freely expressed.

  FIG. 11C shows an example in which the image effect processing mode is the white balance mode. When the picture mode dial 80 is in the WB (white balance) mode and the visibility button 81 is displayed and the PICT button 76 is pressed, the center and right images 102a and 102b in FIG. The effect processing image displayed on the display screen of F display part 18 of finder part 64 is shown. The white balance mode shown in FIG. 11C performs general white balance processing for each color, and shifts the color of the entire image in a specific color direction. When the PICT button 76 is pressed in the white balance mode, the imaging control unit 11a controls the image effect processing unit 11d and the display control unit 11b to display the selection GUI 103 for WB adjustment.

  In the white balance mode, an image obtained by automatically performing white balance adjustment is shifted in a specific color direction by the image effect processing unit 11d. By turning the front dial 73a, for example, selecting a color from twelve colors, and turning the rear dial 73b for the selected color, the adjustment amount can be adjusted in seven steps (0 ± 3 steps). ing.

  The image effect processing unit 11d acquires a setting value in step S101 in FIG. 12C according to the user's selection operation, performs standard image processing on the captured image in step S102, and then uses the acquired setting value to perform color processing. A taste correction process is performed (step S103). During parameter setting, the imaging control unit 11a outputs an effect processing image based on the subject being imaged for display on the F display unit 18 as a live view image (step S104).

  The effect processing image 102a in FIG. 11C shows that the whole is shifted to the cold color system by adjusting blue in the + direction. Further, the effect processing image 102b in FIG. 11C shows that the leaves are vividly finished by adjusting yellowish green in the + direction.

  FIG. 11D shows an example in which the image effect processing mode is ART (art) mode. The middle and right images 112a and 112b in FIG. 11D are displayed when the PICT button 76 is pressed with the visibility priority image 81 displayed when the picture mode dial 80 is in ART (art) mode. The effect processing image displayed on the display screen of F display part 18 of the part 64 is shown. The art mode shown in FIG. 11D performs processing for reducing the saturation other than the selected specific color component. When the PICT button 76 is pressed in the art mode, the imaging control unit 11a controls the image effect processing unit 11d and the display control unit 11b to display the part color selection GUI 113.

  The image effect processing unit 11d reduces the saturation other than the selected specific color component in the art mode. By turning the front dial 73a or the rear dial 73b, for example, a specific color is selected from 12 colors, and the saturation of colors other than the selected color can be reduced.

  The image effect processing unit 11d acquires a setting value in step S105 of FIG. 12D according to the user's selection operation, performs standard image processing on the captured image in step S106, and then uses the acquired setting value to Color processing is performed (step S107). During parameter setting, the imaging control unit 11a outputs an effect processing image based on the subject being imaged for display on the F display unit 18 as a live view image (step S108).

  The effect-processed image 112a in FIG. 11D shows that the portion other than the red flower image portion 115a has become monochrome by selecting red. The effect-processed image 112b in FIG. 11D shows that the portion other than the green leaf image portion 116b has become monochrome by selecting green.

FIG. 11E shows an example in which the image effect processing mode is N (exposure correction) mode. The N mode is a normal shooting mode in which no special processing is performed. In the N mode, only exposure correction is reflected on the captured image. In other words, exposure correction is executed in one mode of image effect processing, and even in the visibility priority image, even exposure correction is not reflected in the captured image.
The images 122a and 122b at the center and the right side of FIG. 11E are obtained when the front dial 73a is rotated while the visibility priority image 81 is displayed when the picture mode dial 80 is in the N (exposure correction) mode. The effect processing image displayed on the display screen of F display part 18 of finder part 64 is shown. Note that the shooting control unit 11a may perform control so that exposure correction is performed by rotating the front dial 73a regardless of the selection of the picture mode dial 80. In the exposure correction mode, when the front dial 73a is rotated, the photographing control unit 11a controls the image effect processing unit 11d and the display control unit 11b to display the exposure value display 127 and the exposure bar 128.

  The effect-processed image 122a in FIG. 11E shows that, by the -1.3 EV correction, a bright sky-clear image portion is appropriate, and the details of the cloud image 129a can be observed. In addition, the effect-processed image 122b in FIG. 11E shows that the flower image portion 125b darkened by the backlight is appropriate by the + 2.3EV correction, and the petal details can be observed.

  As described above, also in this embodiment, the same effect as that of the first embodiment can be obtained.

  In each of the above embodiments, in the visibility priority mode, only the visibility priority image is displayed on the finder display unit, or the visibility priority image including the effect processing image is partially displayed, and the image effect processing is set. In the middle effect processing image display period, the example in which only the effect processing image is displayed or the visibility priority image including the effect processing image in part is displayed on the finder display unit has been described. However, any display method may be used as long as the visibility priority image can be displayed in the normal state and the effect processing image can be displayed in the effect processing image display period. For example, the effect processing image may be displayed on the rear display unit for confirmation of the image effect, and the visibility priority image and the effect processing image are switched and displayed on the rear display unit. Also good.

However, the present invention is not limited to this, and color adjustment is not performed. You may use the captured image which has not performed the HDR synthetic | combination process. Even in a dark scene, in the visibility priority mode, the frame rate may be adjusted to make the display bright and easy to see.

However, the camera may be a digital single lens reflex camera or a compact digital camera, such as a video camera or a movie camera. A camera for moving images may be used, and a camera built in a personal digital assistant (PDA) such as a mobile phone or a smartphone may of course be used. Also, industrial and medical optical instruments such as endoscopes and microscopes may be used. Even if it is not a display device, it is possible to provide an observation device and a display device capable of displaying for capturing an image desired by the user by such a device. Since the visibility priority image and the effect processing image can be switched and displayed, it goes without saying that the object can be observed in detail and effectively used for diagnosis.
