- an automatic still image capturing instruction is also generated.
- a trigger for automatic shutter control based on image analysis is also one of the still image capturing instructions.
- Main exposure (still image imaging exposure) is performed in the image sensor section 12 in response to the shutter operation, but if vibration is generated at this time, there is a possibility that the still image will be blurred. It is sufficient if the amount of blur can be corrected by image stabilization processing, but in some cases, blurring that cannot be corrected may occur.
- the through image displayed on the display panel 4 and viewfinder 5 is displayed after development processing is performed on the captured image signal that has been exposed and read out by the image sensor of the image sensor section 12. There is a time lag until it is displayed. For this reason, even if a notification is provided using vibration or sound at the timing of exposure, for example, a discrepancy occurs between the image that the user recognizes on the display and the image that is recorded as a still image.
- the camera control unit 30 controls the vibration corresponding to the main exposure performed by the image sensor unit 12 in order to generate a still image in response to a still image capturing instruction, to match the exposure period of the main exposure.
- the vibrations are controlled to be generated by the vibration section 32 during different periods.
- FIG. 4 schematically shows the waveform of vibrations generated.
- vibration VB1 indicates vibration of a mechanical shutter.
- An exposure period is obtained by the so-called transition between the leading curtain and the trailing curtain, and vibrations due to this are generated at the timing after exposure.
- the vibration VB2 is an example in which the vibration of the mechanical shutter is generated in a pseudo manner by the vibrating section 32.
- the camera control section 30 causes the vibration section 32 to vibrate at the timing when the exposure period of the main exposure ends.
- the vibration unit 32 does not vibrate during the exposure period, and no blurring occurs in the still image.
- the camera control unit 30 causes the vibration unit 32 to vibrate at the timing when the image related to the main exposure is displayed on the display panel 4 or the viewfinder 5 after the exposure period of the main exposure ends. This is an example of By doing so, not only can vibration be avoided during the main exposure period, but also the user can recognize the image recorded as a still image without any deviation on the display.
- FIG. 5 shows the deviation between the actual scenery and the displayed image during imaging. Assume that exposure is performed on an actual scene as shown as frames F0, F1, F2, and F3.
- the exposure of the scenery shown in frame F1 becomes the main exposure.
- the image displayed on the viewfinder 5 or the like at that time is the image of frame F0, and is not an image recorded as a still image.
- the notification by vibration is made to be performed within the period in which the image of frame F1, which is the main exposure, is displayed.
- FIG. 6 shows the timing of processing up to display in the imaging device 100 during continuous shooting, with the horizontal direction as the time axis.
- exposure EX is the exposure of the image sensor in the image sensor section 12
- readout RD is the readout of the captured image signal from the image sensor section 12
- development DV is the development process by the camera signal processing section 13
- display dp is the image on the display section 15. It shows the display.
- Arrow PF indicates the flow of processing from exposure to display. That is, one frame of exposure EX is performed, after the exposure, readout RD of the captured image signal is performed, development DV is performed on the captured image signal, and through these processes, one frame of image is displayed dp.
- exposure EX and readout RD are repeatedly performed in the image sensor section 12. However, not all exposure is for still image recording, and exposure EX for displaying through images is also performed.
- the main exposure for still image recording (still image imaging exposure) is shown as "EXm" with diagonal lines.
- main exposures EXm1 and EXm2 are used.
- the image data of the frames of the main exposures EXm1 and EXm2 become image data that is recorded as a still image by the recording control section 14 or transmitted externally from the output section 16.
- the display period of the image of the frame of the main exposure EXm (EXm1, EXm2) is shown as a hatched display dpm (dpm1, dpm2).
- vibration for notification is performed during the display period of the image by main exposure as described above.
- vibration is generated within the display periods dpm1 and dpm2.
- the period of vibration performed in accordance with display dpm1 partially overlaps with the period of main exposure EXm2. Therefore, the still image obtained by the main exposure EXm2 may be blurred by the vibration VB10.
- the camera control unit 30 performs control to change the timing of main exposure when an overlap period occurs between the second and subsequent main exposure periods within the continuous shooting period and the display period of images corresponding to the previous main exposures. I do. More specifically, for example, it is possible to change the timing of the main exposure EXm2.
- FIG. 7 shows an example in which the start timing of main exposure EXm2 is shifted. By delaying the start timing of the main exposure EXm2 after the period indicated by the frame W1, it is prevented from overlapping with the period of display dpm1 of the image by the main exposure EXm1. As a result, vibration VB10 is not performed within the period of main exposure EXm2.
- the camera control unit 30 controls the timing of the vibration by the vibration unit 32 when the period of the second or later main exposure within the continuous shooting period overlaps with the display period of the image corresponding to the previous main exposure. Control to change. For example, as shown as vibration VBa2 in FIG. 6, the vibration is started at a timing earlier than the start timing of display dpm1, and the vibration is finished at the start timing tse of main exposure EXm2. This prevents vibration from occurring during the period of main exposure EXm2.
- the camera control unit 30 controls the period during which the vibration is performed by the vibration unit 32 when the period of the second and subsequent main exposures within the continuous shooting period overlaps with the display period of the image corresponding to the previous main exposure. Control is performed to shorten. For example, as shown as vibration VBa3 in FIG. 6, the vibration is started at the start timing of display dpm1, but the vibration is ended at the start timing tse of main exposure EXm2. This prevents vibration from occurring during the period of main exposure EXm2.
- the camera control unit 30 controls the intensity of the vibration by the vibration unit 32 when a period of overlap occurs between the second and subsequent main exposure periods within the continuous shooting period and the display period of the image corresponding to the previous main exposure. Performs weakening control. For example, as shown as vibration VBa4 in FIG. 6, vibration is performed within the period of display dpm1, but by weakening the intensity of the vibration at this time, even if it overlaps with exposure EXm2, it is less likely to have an influence.
- the camera control unit 30 prevents the vibration unit 32 from performing vibration when a period of overlap occurs between the second and subsequent main exposure periods within the continuous shooting period and the display period of images corresponding to the previous main exposures. Do it like this. For example, as shown as vibration VBa5 in FIG. 6, the exposure EXm2 is not affected by not causing vibration within the period of the display dpm1.
- the vibration will be adjusted to the main exposure in the case of continuous shooting, assuming that the vibration is performed in synchronization with the display timing of the still image. It is possible to have no influence (or weaken the influence), and to avoid deterioration in the quality of a series of still images obtained by continuous shooting.
- the camera control unit 30 can determine in advance whether or not the display dpm and the actual exposure EXm overlap during continuous shooting, and in which period the overlap occurs. That is, the frame rate, continuous shooting speed (number of frames: main exposure interval), and shutter speed setting (main exposure time) during continuous shooting are known before the start of continuous shooting. From these, the camera control unit 30 can calculate whether or not an overlap will occur during the continuous shooting period and the timing of the overlap period. For example, if the continuous shooting speed is lower than a predetermined value, no overlap occurs. If the continuous shooting speed is equal to or higher than a predetermined value, the overlapping timing may be calculated from the continuous shooting speed, frame rate, and shutter speed settings. Based on this, it is possible to change the main exposure timing in case (A1), change the vibration timing in (A2), or set the vibration period in (A3).
- FIG. 8 shows a case where the main exposure EXm for a relatively long time is performed according to the user's shutter operation ST due to the shutter speed setting. For example, assume a long-time exposure with an exposure time of about 1 second.
- vibration or sound notification is performed during the display period, as shown in vibration VB3 in FIG. 4.
- vibration is performed immediately after the shutter operation ST, such as vibration VB21.
- vibration is performed before exposure.
- the camera control unit 30 additionally switches the main exposure when performing main exposure for a predetermined time or longer in response to a still image capturing instruction such as shutter operation.
- the vibration unit 32 is controlled to vibrate even during the display dpm period of the image based on the captured image signal obtained by exposure. For example, as shown in vibration VB22 in FIG. 8, vibration is performed immediately after shutter operation ST, and also during the display dpm period. As a result, in addition to vibrations corresponding to the operation, vibrations are also performed to present a still image to be recorded.
- the camera control unit 30 controls the camera control unit 30 so that each vibration is performed in a different vibration mode. You can also do this.
- the vibration VB23 in FIG. 8 shows an example in which the vibration time is different between the vibration in response to the shutter operation ST and the vibration in response to the display dpm. This allows the user to understand the meaning of vibrations that correspond to operations and vibrations that indicate still images to be recorded.
- the different vibration modes may include changing the vibration intensity, changing the vibration pattern, or changing the vibration frequency. Further, differences may be made by combining vibration time, vibration intensity, vibration frequency, and vibration pattern.
- the camera control unit 30 controls the shutter operation, etc. when performing main exposure for a predetermined time or longer in response to a still image capturing instruction such as a shutter operation. Control is performed to start the main exposure after the vibration at the time of instructing to capture a still image has ended. This prevents vibration from affecting the main exposure EXm.
- the camera control unit 30 determines that the imaging device 100 is not being held by the user, the camera control unit 30 prevents one or both of vibrations during still image capture instructions such as shutter operation, and vibrations within the display dpm period. to control.
- the vibration Prevent notifications from being made. This is because when the user is not holding the main body casing 1, the user is less likely to feel the vibration, and the vibration does not function well as a notification.
- the notification may be made by sound as well as vibration. Furthermore, in the case of (B3'), the notification may be made by sound instead of vibration.
- the camera control unit 30 can determine the result of the imaging situation at a time before the notification.
- the imaging situation determination result is, for example, as follows. - Is image stabilization successful (normal) or unsuccessful (abnormal)? ⁇ Is the exposure appropriate (normal), or is it determined to be over or under exposure (abnormal)? ⁇ Is the tracking subject captured (normal) or is it lost (abnormal)? ⁇ Is it in focus (normal) or out of focus (abnormal)?
- some or all of these determination results are presented during the display dpm period. Note that since the period of the display dpm is instantaneous for the user, it is difficult to present in detail whether each period is normal or abnormal. Therefore, for example, the user may be able to select which of the above determination results to present. Alternatively, for the plurality of determinations described above, if all of the determinations are normal, it is determined to be "normal”, and if any one of the determinations is abnormal, "abnormal" may be presented.
- the display dpm is performed for the image of the main exposure EXm.
- the camera control unit 30 controls the vibration VB30 if it is "normal”, and controls the vibration VB31 if it is "abnormal". Control. This allows the user to immediately know whether the still image captured by the shutter operation has been successfully captured or failed.
- Sound notification may be provided in conjunction with the vibrations VB30 and VB31. In that case, by making the sound for vibration VB30 and the sound for vibration VB31 different sounds, it is possible to present to the user whether the imaging is normal or abnormal. Note that the presentation may be performed using sound instead of using vibration.
- FIG. 10 is an example in which the determination result of the imaging situation is presented by changing the display mode of the entire still image.
- a normal display mode is shown as a through image, as well as a case of normal presentation and a case of abnormal presentation.
- normal presentation in the figure, the entire screen of the through image is dotted, but for example, it is assumed that the entire screen is displayed in see-through blue.
- abnormality presentation the entire screen of the live-through image is shaded, but the entire screen is displayed in see-through red, for example. By doing this, the user can visually recognize the contents of the subject and recognize whether it is normal or abnormal depending on whether the overall color is blue or red.
- the displayed image changes every frame, but as shown in FIG. 11, if an entirely blue image is displayed after the shutter operation ST, the user can It can be recognized that the still image capturing by ST was successful. Further, as shown in FIG. 12, if an entirely red image is displayed after the shutter operation ST, the user can recognize that the still image capturing by the shutter operation ST has failed.
- FIG. 13 is an example in which the determination result of the imaging situation is presented by changing the display mode of the peripheral area in the still image.
- the frame-shaped peripheral area 60 is displayed in see-through blue for normal presentation, and the frame-shaped peripheral area 60 is displayed in see-through red for abnormal presentation. It is a case.
- This example also appears in the through image, making it easy for the user to recognize the success or failure of imaging.
- by presenting the image in the peripheral area 60 there is an advantage that the subject can be easily recognized in the central area.
- FIGS. 14 and 15 are examples of changing the display mode depending on the amount of abnormality in under- or over-exposure situations.
- FIG. 14 when the image is normal, a normal live view image is displayed, but when the exposure is underexposed, the intensity of blue in the peripheral area 60 is changed according to the amount of abnormality. Furthermore, in the case of overexposure, the intensity of red in the peripheral area 60 is changed depending on the amount of abnormality.
- the user can recognize under/over conditions based on the color of the peripheral area 60, and can recognize the degree of abnormality based on the darkness of the color.
- FIG. 15 is an example in which the size of the peripheral area 60 to be colored blue or red is changed depending on the amount of abnormality in under- or over-exposure situations. If it is normal, a normal through image is displayed, but if the exposure is underexposed, the size of the blue peripheral area 60 (width of the frame) is changed depending on the amount of abnormality. If the exposure is overexposed, the size of the red peripheral area 60 (width of the frame) is changed depending on the amount of abnormality. With such a display, the user can recognize under/over conditions based on the color of the peripheral area 60, and can recognize the degree of abnormality based on the size of the colored area.
- a similar display may be made depending on the amount of abnormality in the front focus, back focus, etc. of the in-focus state (focus). Furthermore, a similar display can be made depending on the amount of image blur due to camera shake during exposure or shaking of the main body housing 1.
- Vibration according to lens barrel> When performing vibration as a notification during the display dpm period, etc. in response to the shutter operation, etc. described above, or as a presentation of the determination result of the imaging situation, depending on the lens barrel 2 attached.

- the camera control unit 30 may change the vibration mode depending on the type of the lens barrel 2.
- the camera controller 30 can acquire information such as the model number and type of the lens barrel 2 through communication with the lens barrel controller 23 . Therefore, the vibration mode at the time of vibration is selected depending on the lens barrel 2. This allows the user to appropriately perceive vibrations regardless of the lens barrel 2.
- the vibration mode to be changed includes vibration intensity, vibration frequency, length of vibration period, vibration pattern, and the like.
- the camera control unit 30 determines in step S101 whether the current shooting style is hand-held.

- step S102 determines whether the scheduled time for the current main exposure is equal to or longer than the predetermined time thT. In other words, it is determined whether the exposure at the currently set shutter speed is a long exposure. The reason for determining whether or not it is a long exposure is for the above-mentioned process (B1).
- step S105 If it is not a long exposure, the process advances to step S105. If it is a long exposure, the camera control unit 30 proceeds to step S103 and controls the operation reception vibration. That is, control is performed to cause the vibrating section 32 to perform vibrations corresponding to the shutter operation, etc. as explained in the vibrations VB21, VB22, and VB23 in FIG.
- step S104 the camera control unit 30 waits for the vibration unit 32 to stop vibrating.

- the camera control unit 30 causes the image sensor unit 12 to execute the main exposure EXm when proceeding to step S105 from any one of steps S101, S102, and S104. Thereafter, in step S106, post-notification processing is performed as control until the display period of the image related to the main exposure EXm. Although the details of the post-notification process will be described later, the vibration control described in (A1) to (A5) or (B1), (B2), and (B2') above is performed by this post-notification process.
- step S107 the camera control unit 30 determines whether continuous shooting is being continued. In the case of single-shot imaging or when the continuous shooting operation has been completed, the camera control unit 30 ends the process from step S107.
- the camera control unit 30 returns from step S107 to step S104 and waits for the vibration to stop.
- the standby in this case is a standby for vibration to be performed at the display dpm.
- the start of the main exposure EXm is delayed so that the vibration and the main exposure EXm do not overlap.
- the camera control unit 30 starts the main exposure in step S105.

- Other processing is the same.
- this second process example can be considered.
- the camera control unit 30 determines in step S120 whether the current shooting style is hand-held. If the camera is not in hand, the camera control unit 30 ends the post-notification process. In other words, in this case, notification of vibration, etc. during the display dpm period is not performed. This also corresponds to the process (B3') described above.
- the camera control unit 30 proceeds to step S121 and determines whether or not prior notification has been given regarding the current still image capturing.
- the prior notification here refers to a notification by vibration in response to a shutter operation or the like in the case of long exposure. Specifically, this is the vibration executed in step S103 in FIG.

As a result, as in the process (B1) described above, in the case of long exposure, vibration in accordance with the display dpm1 is not performed.
- step S102 advances from step S102 to step S105.
- the camera control unit 30 proceeds from step S121 to step S122 and subsequent steps in FIG. 18, and controls vibration in accordance with the display dpm.
- the camera control unit 30 determines whether or not the current imaging is based on the high-speed continuous shooting setting.
- the user can select the continuous shooting speed.
- Continuous shooting at a certain continuous shooting speed or higher is defined as high-speed continuous shooting.
- the high-speed continuous shooting referred to here is a continuous shooting speed at which the display dpm periods of images related to the second and subsequent main exposures of the continuous shooting period and the previous main exposures overlap.
- the process advances to step S123.
- step S123 the camera control unit 30 causes the readout of the captured image signal by the main exposure in the previous step S105 (FIGS. 16 and 17), and in step S124 causes the camera signal processing unit 13 to execute development processing.

- step S134 the camera signal processing unit 13 can perform control to display the image to be displayed in a display mode that presents the determination result of the imaging situation. That is, the display mode in display dpm is controlled according to the result of the development process in step S133.
- the camera control unit 30 waits for a predetermined timing in step S130, and then performs vibration processing in step S131.
- the vibration processing in this case is one of (A2), (A3), and (A4), or a combination of them.
- the predetermined time period for waiting in step S130 is the time period up to a point slightly before the display dpm start timing.
- the predetermined waiting time in step S130 is the time until the display dpm start timing.

- the normal vibration and the short vibration only need to differ in at least the vibration duration time, but in addition, the vibration frequency, pattern, and vibration intensity may also be different.
- FIG. 22 shows a second example of vibration processing.
- the camera control unit 30 checks whether the high-speed continuous shooting setting is on in step S150, and if the high-speed continuous shooting setting is not set, that is, in the case of imaging with the low-speed continuous shooting setting or single-shot imaging, the camera control unit 30 turns on the normal vibration in step S155.

- the three values are three values indicating normal, under, and over.
- In the in-focus state there are three values indicating normal, front focus, and back focus.
- step S170 the camera control unit 30 determines the development processing result of the image to be displayed. For example, the exposure state is determined.

- the imaging device of the embodiment includes an image sensor unit 12 that exposes incident light and outputs a captured image signal, a vibration unit 32 as a notification unit, and an image sensor unit that generates a still image in response to a still image imaging instruction.
- the camera controller 30 includes a camera control unit 30 that controls a notification unit (vibration unit 32) to execute a notification corresponding to the main exposure (still image capturing exposure) performed by the unit 12 in a period different from the exposure period of the main exposure.
- the vibration unit 32 is mainly cited as an example of the notification unit, and the user is notified by vibration, but instead of vibration, or in addition to vibration, notification by sound such as an electronic sound or shutter sound, or notification by display can also be used. In some cases, notifications may be provided by emitting light from an LED or the like.
- the camera control unit 30 may control the notification unit to perform the notification in a period different from the exposure period of the main exposure. Further, the mode of notification can be changed in the same way as in the case of the vibrating section 32. For example, there are differences in pitch, timbre, melody, and voice, differences in light emission patterns, light emission intensity, and light emission cycles, and differences in display content.
- the camera control unit 30 controls an example in which the vibration unit 32 performs vibration corresponding to the main exposure within a display period of an image based on a captured image signal obtained by the main exposure.
- the captured image signal read out from the image sensor unit 12 is developed in the camera signal processing unit 13, and then an image based on the captured image signal is displayed on the viewfinder 5 or It is displayed on the display panel 4.
- the user can recognize that the image displayed at the time of vibration is an image to be recorded (or transmitted) as a still image.
- the user can recognize which image is being recorded by the vibrations while a series of scenes are displayed as through images during continuous shooting.
- the camera control unit 30 controls the main exposure when an overlapping period occurs between the second and subsequent main exposure periods within the continuous shooting period and the display period of the image corresponding to the previous main exposure.
- An example of controlling to change the timing has been described (processing (A1)).
- the period of a certain still image shooting exposure may overlap with the display period of the image from the previous still image shooting exposure (main exposure EXm).
- main exposure EXm main exposure
- vibrations may occur during exposure, which may cause blur in the recorded still image. Therefore, the timing of still image imaging exposure is changed to avoid overlapping periods (see FIGS. 8 and 16).
- FIGS. 8 and 16 As a result, even in the case of continuous shooting, it is possible for the user to match the display timing of the vibration and the still image to be recorded, and to prevent blurring from occurring in the still image.
- the camera control unit 30 controls the vibration unit 32 when an overlap period occurs between the second and subsequent main exposure periods within the continuous shooting period and the display period of the image corresponding to the previous main exposure.
- An example has been described in which control is performed to change the timing of vibration (process (A2), vibration VBa2 in FIG. 6, see FIG. 18).
- the vibration timing is changed to avoid the overlap of the periods.
- the user even in the case of continuous shooting, it is possible for the user to make the vibration and the display timing of the recorded still image approximately coincide with each other, and to prevent blurring from occurring in the still image.
- Another advantage is that high-speed continuous shooting performance is not degraded by not changing the timing of main exposure.
- both the vibration timing and the main exposure timing may be changed so that they do not overlap. For example, if a relatively large change in vibration timing is required and there is a large discrepancy between display and vibration, it may be possible to shift the exposure timing to bring the vibration and display timing closer together. For example, it is possible to advance the vibration timing by half the overlapping period length and delay the start of the next main exposure by half the time.
- the camera control unit 30 controls the vibration unit 32 when an overlap period occurs between the second and subsequent main exposure periods within the continuous shooting period and the display period of the image corresponding to the previous main exposure.
- An example has been described in which control is performed to shorten the execution period of vibration (process (A3), vibration VBa3 in FIG. 6, see FIG. 21).
- process (A3), vibration VBa3 in FIG. 6, see FIG. 21) As a result, even in the case of continuous shooting, it is possible for the user to make the vibration and the display timing of the recorded still image approximately coincide with each other, and to prevent blurring from occurring in the still image.
- Another advantage is that high-speed continuous shooting performance is not degraded by not changing the timing of main exposure.
- the camera control unit 30 controls the vibration unit 32 when an overlap period occurs between the second and subsequent main exposure periods within the continuous shooting period and the display period of the image corresponding to the previous main exposure.
- An example has been described in which control is performed to weaken the intensity of vibration caused by (processing (A4), vibration VBa4 in FIG. 6, see FIG. 22).
- processing (A4), vibration VBa4 in FIG. 6, see FIG. 22 To extremely reduce the possibility that a still image will be affected by blur by weakening the intensity of vibration.
- Another advantage is that high-speed continuous shooting performance is not degraded by not changing the timing of main exposure.
- the camera control unit 30 controls the vibration unit 32 when an overlap period occurs between the second and subsequent main exposure periods within the continuous shooting period and the display period of the image corresponding to the previous main exposure.
- An example has been described in which control is performed to prevent vibration from being performed (process (A5), vibration VBa5 in FIG. 6, see FIG. 20). Thereby, it is possible to prevent blur from occurring in still images obtained by continuous shooting. There is also the advantage that high-speed continuous shooting performance is not degraded by not changing the timing of main exposure.
- the camera control unit 30 controls the presence or absence of notification by the notification unit such as the vibration unit 32 or the execution timing of the notification, depending on the exposure time of still image imaging exposure. More specifically, in the embodiment, when performing main exposure for less than a predetermined time in response to a still image capturing instruction, camera control unit 30 displays an image based on a captured image signal obtained by main exposure. The vibration unit 32 is controlled to perform vibration corresponding to the main exposure within the period. On the other hand, when performing main exposure for a predetermined time or longer in response to a still image imaging instruction, the vibration unit 32 performs the main exposure for a predetermined time or longer, regardless of whether the vibration at the time of the still image imaging instruction is within the still image imaging exposure period.
- the vibration in this case may occur before the start of exposure, but may occur at the time of starting exposure.
- the exposure is for a long time, even if the image vibrates for some time during the exposure, there is almost no effect of blurring due to the vibration, so it can be considered that there is no problem.
- the camera control unit 30 when performing main exposure for a predetermined time or more in response to a still image imaging instruction, uses a captured image signal obtained by the main exposure in addition to the vibration at the time of the still image imaging instruction.
- An example has been described in which the vibration corresponding to the main exposure is controlled to be performed by the vibration unit 32 even during the display period of the image based on the image (see the process in (B2), the vibration VB22 in FIG. 8, and FIG. 19).
- the main exposure is a long exposure, in addition to performing vibration immediately in response to the shutter operation (see step S103 in FIG. 16), vibration is also performed during the display period during which the main exposure image is displayed. (Step S125 or S131 in FIG. 19). This eliminates the discomfort caused by vibration, and also allows the user to vibrate during the still image display period, making it easier for the user to understand the still image to be recorded.
- the camera control unit 30 causes the vibration unit 32 to perform vibration in response to a still image capturing instruction, and causes the vibration unit 32 to perform vibration within an image display period based on a captured image signal obtained by main exposure.
- An example has been described in which the vibration is controlled to have a different vibration mode (process (B2'), see vibration VB24 in FIG. 8).
- the vibration in response to the shutter operation and the vibration during the display period are made to differ, for example, in vibration time, vibration intensity, vibration pattern, etc. This allows the user to feel the difference in meaning of each vibration.
- the camera control unit 30 when performing main exposure for a predetermined time or more in response to a still image capturing instruction, performs control to start the main exposure after the vibration at the time of the still image capturing instruction ends.
- An example has been described (see the process (B3) and steps S104 and S105 in FIG. 16). If vibration is performed immediately in response to a shutter operation, and the vibration period and the main exposure period overlap, there is a possibility that a still image will be affected by blur depending on the case. Therefore, the main exposure is started after the vibrations caused by the shutter operation have subsided. This can prevent blurring due to vibration.
- the camera control unit 30 determines that the user is not holding the camera hand-held, the camera control unit 30 generates vibrations when instructing to capture a still image, or vibrations during an image display period based on a captured image signal obtained by main exposure.
- control is performed so as not to execute one or both of the following (see the process (B3'), step S101 in FIG. 16, and step S120 in FIG. 18).
- the imaging device 100 is attached to a tripod to capture an image or when an operation is performed using a remote controller, even if the main body casing 1 is vibrated, the user is not notified. Therefore, notification is made only when hand-held imaging is performed to avoid unnecessary vibrations. Note that either one of the vibrations in response to the shutter operation and the vibrations during the display period may be performed. This is because even if a tripod or the like is used, the user may still be touching the main body casing 1, for example.
- the camera control unit 30 performs control to present the determination result of the imaging situation during the display period of the image based on the captured image signal obtained by the main exposure. For example, after the shutter operation is performed, main exposure is performed, after the main exposure, development processing is performed, and then the still image is displayed. Therefore, the imaging situation can be determined during display. Therefore, the imaging situation is presented in a display manner (see FIGS. 10 to 15). This allows the user to know the imaging situation immediately or during continuous shooting. It has also been described that the vibration performed during image display is presented based on the determination result of the imaging situation (see FIGS. 9, 23, and 24). That is, changing the vibration mode depending on the imaging situation while displaying an image is also an example of control for displaying an image based on a captured image signal in a manner that presents the determination result of the imaging situation. This also allows the user to know the imaging situation.
- the situation of image stabilization As the determination result of the imaging situation, the situation of image stabilization, the situation of overexposure, the situation of underexposure, the tracking of a tracked subject, the situation of lost, and the situation of in-focus and out-of-focus are listed. Since these situations can be determined at the development processing stage, they are suitable for simultaneous display during static display. This also gives the user an opportunity to immediately improve the situation.
- the camera control unit 30 presents the determination result of the imaging situation by changing the display mode of the entire still image.
- the camera control unit 30 presents the determination result of the imaging situation on the entire screen as shown in FIG. 10, it becomes easier for the user to recognize even a momentary image during live view display.
- the camera control unit 30 causes the determination result of the imaging situation to be presented by changing the display mode of the peripheral area in the still image.
- Figure 13 by displaying the subject normally in the central area of the screen and presenting the imaging situation in the display mode of the peripheral area, visibility of the subject is ensured, while the momentary image during the through image display is displayed. Even if there is, the user can easily recognize the imaging situation.
- the camera control unit 30 changes the display mode in stages according to the determination result of the imaging situation.
- the user can recognize the degree of abnormality in the imaging situation.
- the camera control unit 30 determines the vibration mode of the vibration unit 32 by the type of the lens barrel 2 attached to the main body housing 1.
- An example of setting according to information has been given (see FIGS. 25 and 26). The way the user feels the vibration changes depending on the weight, center of gravity, etc. of the lens barrel 2.
- notifications using vibrations have been mainly described, but instead of notifications using vibrations, or in addition to notifications using vibrations, notifications using sounds may be performed. For example, by making an electronic sound, a sound resembling a shutter operation, or the like during the display dpm period, it is possible to obtain the effect of clearly showing the still image to be recorded to the user.
- the program of the embodiment is a program that causes a CPU, a DSP, etc., or a device including these, to execute the processes described in FIGS. 16 to 25, for example. That is, the program of the embodiment includes arithmetic processing for controlling the imaging device 100, which includes an imaging device section 12 that exposes incident light and outputs a captured image signal, and a notification section (for example, a vibration section 32 that vibrates the housing).
- This is a program that causes a device (for example, the camera control unit 30) to execute processing.
- the program sends a notification by vibration or the like corresponding to still image imaging exposure performed by the image sensor unit 12 to generate a still image in response to a still image imaging instruction, and determines the exposure period of the still image imaging exposure.
- This causes the arithmetic processing unit to execute the control that is executed by the notification unit during different periods. With such a program, the imaging device 100 of the present disclosure can be easily implemented using an arithmetic processing device.
- Such a program can be recorded in advance in an HDD (Hard Disk Drive) as a recording medium built into equipment such as a computer device, or in a ROM in a microcomputer having a CPU.
- a flexible disk, a CD-ROM (Compact Disc Read Only Memory), an MO (Magneto Optical) disk, a DVD (Digital Versatile Disc), a Blu-ray Disc (registered trademark), a magnetic disk, a semiconductor memory It can be stored (recorded) temporarily or permanently in a removable recording medium such as a memory card.
- a removable recording medium can be provided as so-called package software.
