Description

[Technical field]

[0001] The present invention relates to an imaging device. [Background technology]

[0002] Conventionally, imaging devices equipped with a shake correction means for correcting image shake caused by camera shake are known. When image shake is corrected by such a shake correction means, the viewfinder display goes black during still image capture, making it impossible to check the state of the subject. Meanwhile, due to recent improvements in the performance of camera shake correction means, there are more and more opportunities to take still images (long exposure) while holding the camera. In such cases, it is inconvenient for the user if the subject being captured or the state of the imaging device cannot be checked using the viewfinder for a long period of time.

[0003] Patent Document 1 discloses an imaging device that notifies a user of the state of camera shake during exposure by displaying the movement of the imaging device on a viewfinder. [Prior art documents] [Patent documents]

[0011] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

[0012] First, an image pickup device 1000 equipped with an anti-shake control device (shake correction means) in this embodiment will be described with reference to Fig. 1. Fig. 1 is a configuration diagram of the image pickup device 1000, Fig. 1(a) is a cross-sectional view of the image pickup device 1000, and Fig. 1(b) is a block diagram of the image pickup device 1000. Note that in Fig. 1(a) and Fig. 1(b), the same members are given the same reference symbols.

[0013] The imaging device 1000 is configured to include a camera body 1 and a lens device (interchangeable lens) 2 that is detachable from the camera body 1. The lens device 2 and the camera body 1 are connected via an electrical contact 11. However, this embodiment is not limited to this, and can also be applied to an imaging device in which the camera body and the lens device are integrally configured.

[0014] The optical axis 4 is the optical axis of the optical system (imaging optical system) 3 of the lens device 2. The lens device 2 is provided with a lens driving means 13 so that the light beam from the subject that has passed through the lens device 2 can form a good image on the imaging element 6 of the camera body 1. The lens driving means 13 drives the optical system 3 upon receiving a control signal from the lens system control unit 12. The optical system 3 is provided with a focus adjustment unit, an aperture driving unit, an image stabilization lens 9, and the like. The shutter mechanism 17 is driven and controlled by the shutter driving means 18 so that exposure is performed at a shooting time (shutter speed) set by the user or determined by the camera system control unit 5. The imaging element 6 is a CMOS sensor or a CCD sensor, and photoelectrically converts the subject image (optical image) formed via the lens device 2 to output image data.

[0015] The camera system control unit 5 calculates a shake compensation amount for reducing the influence of shake based on the signals output from the release detection unit 7, the operation detection unit 8, the angular velocity detection means 15, and the acceleration detection means 16. The camera system control unit 5 then outputs the calculated shake compensation amount to the shake compensation means 14 and the lens system control unit 12. The camera system control unit 5 also functions as a display control means that controls the shake display means 10 so that the shake display means 10 displays the angular shake information and translational shake information calculated by the display shake information calculation means 100 separately.

[0016] The operation detection unit 8 detects user operations such as shutter speed, F-number, and mode settings. The shake correction means 14 drives the imaging element 6 based on the shake correction amount received from the camera system control unit 5. The camera body 1 is provided with a release detection unit 7. The release detection unit 7 detects an open / close signal of a release (not shown) and sends the detected open / close signal to the camera system control unit 5. There are two types of open / close signals detected by the release detection unit 7. The release detection unit 7 can detect a two-stage switch, switch 1 (SW1) that presses the release detection unit 7 halfway and switch 2 (SW2) that presses it fully.

[0017] The z-axis in FIG. 1(a) is parallel to the optical axis 4. The x-axis and y-axis are each perpendicular to the z-axis and parallel to each side of the image sensor 6. For ease of viewing, the origin is drawn outside the image sensor 1000 in FIG. 1, but in reality the origin is at the center of the image sensor 6. In this embodiment, the shake display means (display means) 10 includes a rear display device 10a provided on the rear of the camera body 1 and an EVF (electronic viewfinder) 10b provided in the finder of the camera body 1, but is not limited thereto. The shake display means is not limited to those included in the image sensor 1000. For example, the screen of a mobile terminal connected to the image sensor 1000 can function as the shake display means. The display of the shake display means 10 is controlled by the camera system control unit 5.

[0018] The lens system control unit 12 outputs a command based on the shake correction amount to the lens driving means 13. The lens driving means 13 drives the image shake correction lens 9 in the x direction and the y direction in FIG. 1(a) to perform shake correction taking into account both angular shake (angular shake information) and translational shake (translational shake information). The shake correction means 14 drives the image sensor 6 in the x direction and the y direction in FIG. 1(a) to perform shake correction taking into account both angular shake and translational shake. The shake correction means 14 also performs shake correction taking into account both angular shake and translational shake caused by the rotational motion around the z axis by driving the image sensor 6 to rotate around the z axis. Note that the correction method based on the shake correction amount received from the camera system control unit 5 is not limited to this method, and other methods may be used. For example, there is a method of using electronic image stabilization by image alignment synthesis. In addition, a correction method that appropriately combines these may be used.

[0019] Shake (hand shake) occurs when the user holds the imaging device 1000, and the shake is classified into angular shake and parallel shake (shift shake). Angular shake is shake caused by the imaging device 1000 rotating around the x-axis, y-axis, or z-axis. Parallel shake is shake caused by the imaging device 1000 moving in translation along the x-axis, y-axis, or z-axis.

[0020] Fig. 2(a) is an image diagram of an image captured by the image sensor 6 when no shake occurs. Figs. 2(b) to 2(g) are image diagrams of captured images when angular shake and translation shake are present with respect to the captured image of Fig. 2(a). Fig. 2(b) is an image diagram of a captured image when rotated around the x-axis, Fig. 2(c) is an image diagram of a captured image when rotated around the y-axis, and Fig. 2(d) is an image diagram of a captured image when rotated around the z-axis. Fig. 2(e) is an image diagram of a captured image when translated in the x-axis direction, Fig. 2(f) is an image diagram of a captured image when translated in the y-axis direction, and Fig. 2(g) is an image diagram of a captured image when translated in the z-axis direction.

[0021] Rotation around the z-axis appears in the captured image as a vibration that rotates around the center of the image, as shown in Figure 2(d). Translation along the z-axis appears in the captured image as a vibration that spreads radially from the center of the image, as shown in Figure 2(g). Rotation around the x-axis and translation along the y-axis appear in the captured image as a vibration that spreads vertically, as shown in Figures 2(b) and 2(f). Rotation around the y-axis and translation along the x-axis appear in the captured image as a vibration that spreads horizontally, as shown in Figures 2(c) and 2(e).

[0022] Angular shake and translational shake differ in the nature of the way the imaging device 1000 shakes, and the formula for converting the amount of shake of the imaging device 1000 into the amount of shake on the image plane also differs. Although angular shake and translational shake are shakes of different nature, some shakes appear as shakes of the same nature on the captured image. If the two are displayed together on the shake display means 10 as shakes of the same nature on the captured image, the user cannot determine whether the shake is angular shake or translational shake, and cannot try to reduce the shake correctly.

[0023] Next, a method of displaying angular shake and translational shake separately on the shake display means 10 will be described with reference to FIG. 3. As described with reference to FIG. 2, rotation around the z-axis and translation in the z-axis direction are different in nature from other shakes on the image plane, and therefore are not usually displayed together with other shakes. For this reason, in this embodiment, a method of displaying rotation around the x-axis, rotation around the y-axis, translation in the x-axis direction, and translation in the y-axis direction separately will be described. Note that in this embodiment, rotation around the z-axis and translation in the z-axis direction may also be displayed separately.

[0024] Fig. 3(a) shows the display when no shake is occurring. Angular shake and translational shake are displayed separately based on the inclination and movement of the rod (object). Fig. 3(b) is an image diagram of the display when angular shake is applied, with the inclined rod representing the state in which angular shake is applied. Fig. 3(c) is an image diagram of the display when translational shake is applied, with the moving rod representing the state in which translational shake is applied. Fig. 3(d) shows the state in which Fig. 3(b) and Fig. 3(c) are combined, with the inclination of the rod representing angular shake and the movement of the rod representing translational shake. Note that Figs. 3(b) to (d) show multiple rods simultaneously to represent the shake state, but only one rod is displayed at a time.

[0025] In Figures 3(b) to (d), the user may indicate a standard to be targeted, for example, by always displaying a bar when no shaking is occurring. To make the bars indicating the shaking state easier to see, the standard bar may be displayed in a lighter color, and the display method is free. To show the history of shaking, the bars that have been displayed so far may be displayed in a lighter color.

[0026] In the example of Fig. 3(a) to (d), the angular shake is displayed by the angle change (tilt) of the rod, and the parallel shake is displayed by the parallel movement of the rod. However, this embodiment is not limited to this, and a method of displaying both the angular shake and the parallel shake by the angle change or by the parallel movement may be used. Both the angular shake and the parallel shake can be converted into the shake on the image plane, so they can be expressed as a parallel movement. The angular shake is originally a shake caused by an angle change, so it can be expressed as an angle change. The parallel shake can be displayed as an angle change by calculating how much the angle change will be if it is assumed that the shake on the image plane caused by the parallel shake is caused by an angle change. It is possible to change whether the parallel shake and the angular shake are expressed by an angle change or by a parallel movement depending on the display method. In order to match the user's sense, the angular shake is displayed by an angle change and the parallel shake is displayed by a parallel movement, but the reverse is also possible, and the application method is also free. For parallel and angular shake, the most intuitive and easy-to-understand method is to display parallel shake as a translation and angular shake as an angle change, as shown in Figures 3(a) to (d), in accordance with the nature of the shake.

[0027] Next, referring to Figs. 4(a) to (d), an example of displaying translational shake as translational movement and angular shake as angle change, similar to Figs. 3(a) to (d), will be described. Fig. 4(a) is a display when no shake occurs. Fig. 4(b) is an image diagram of a display when translational shake occurs. Fig. 4(c) is an image diagram of a display when angular shake occurs. Angular shake is displayed by the angle change of an object. Fig. 4(d) is an image diagram when angular shake and translational shake are displayed simultaneously. Fig. 4(d) shows a combination of Figs. 4(b) and 4(c), where angular shake is displayed by the angle change of an object, and translational shake is displayed by the translation of the object. Note that Figs. 4(b) to (d) show multiple objects simultaneously to express the shake state, but only one object is displayed at the same time.

[0028] In Fig. 4(b) to (d), the user may indicate a reference to be targeted, for example, an object without shaking may be constantly displayed. In order to make the object showing the shaking state easier to see, the reference object may be displayed in a dim light, and the display method is free. In order to show the history of shaking, the objects displayed so far may be displayed in a dim light light. The objects in Fig. 4(a) to (d) may be any object whose angular change can be seen, and the shape is not important. The shape may be, for example, the coordinate axes of three axes xyz, or the shape of a camera. Thus, in this embodiment, the shake display means 10 can display angular shake information based on the angular change of the object, and can display translation shake information based on the translation of the object.

[0029] Next, with reference to Fig. 5(a) to (e), an example in which both angular shake and translational shake are displayed as translational movement will be described. Fig. 5(a) is an image of the display when no shake occurs. The angular shake is displayed by moving a black circle, the angular shake around the z-axis is displayed by rotating the entire figure, and the translational shake is displayed by moving the entire figure. Figs. 5(a) to (e) show a display example when shakes of different properties occur alone and a display example when they occur simultaneously. Fig. 5(b) is an image diagram of the display when only angular shakes around the x-axis and y-axis occur. The angular shake around the y-axis is shown by the left-right movement of a black dot in the figure, and the angular shake around the x-axis is shown by the up-down movement of a black dot in the figure. The user takes a picture with the aim of matching the two points to the middle point. The display of the middle point may be devised in such a way that it is displayed in gray when only one point exists in the middle, and in black when both points exist in the middle. Also, instead of color, they can be divided by shape, and if one point is in the middle, it can be a circle, and if both points are in the middle, it can be a star, etc. Also, although they are displayed separately on the x-axis and y-axis, it is also possible to display composite points by setting up a place to display points diagonally.

[0030] FIG. 5(c) is an image diagram when only angular shake around the z-axis is displayed. Shake is displayed by rotating the entire figure. FIG. 5(d) is an image diagram when only translational shake is displayed. Translational shake is displayed by moving the entire figure. FIG. 5(e) is an image diagram when the shakes described in FIG. 5(b) to (d) are displayed together. It can be seen that the shakes are displayed separately according to their characteristics. As mentioned above, angular shake and translational shake can also be displayed in reverse. In this way, in this embodiment, the shake display means 10 can display angular shake information based on the movement of a point, and can display translational shake information based on the movement of the entire figure showing the movement of the point.

[0031] Next, referring to Figs. 6(a) to (c), an example will be described in which only angular shake around the x- and y-axes and translational shake in the x- and y-axis directions are displayed, and each is displayed as a translation. Fig. 6(a) is an image diagram of a display in a state where no shake occurs. Angular shake is displayed by moving a circle in a circle on the left side, and translational shake is displayed by moving a circle in a circle on the right side. The movement range of the circle may not be a circle, but may be a square, etc. Figs. 6(b) and 6(c) are image diagrams in which the size of the display is changed according to the ratio (ratio information) of angular shake and translational shake. Fig. 6(b) is a display when angular shake is dominant, and Fig. 6(c) is a display when translational shake is dominant. If the circle moving in the circle is made into a shape that shows the angle change, angular shake around the z-axis can be displayed, and translational shake in the z-axis direction can also be displayed by changing the size of the circle. In Fig. 6(a) to (c), the angular shake and the translational shake are displayed as translations, but by making the moving figure a square or other figure capable of displaying an angle change, each may be displayed as an angle change instead of a translational movement. In this manner, in this embodiment, the shake display means 10 can separate the angular shake information and the translational shake information by dividing the display positions of the angular shake information and the translational shake information. In addition, the shake display means 10 can display ratio information calculated based on the angular shake information and the translational shake information. Note that, although several display examples have been shown as described above, it is also possible to display only the dominant type of shake among the angular shake and the translational shake. In other words, the shake display means 10 can display information on the angular shake information and the translational shake information that has a larger shake amount.

[0032] Next, referring to FIG. 7, an example of displaying shake information together with user movement information, which is closer to intuition, will be described. FIG. 7(a) shows the display of the rotation around the z-axis and the translation shake in the x-axis direction. Both the rotation around the z-axis and the translation shake in the x-axis direction are generated by the user's motion of falling left and right like a pendulum, so they can be displayed together. The rotation radius of the user's pendulum-like motion can be calculated from the ratio of the rotation around the z-axis and the translation shake in the z-axis direction. The user's shake is displayed using the rotation radius and the rotation around the z-axis or the translation shake in the x-axis direction. The display may show the direction in which the user should fall as shown in FIG. 7(a), or may show the direction in which the user is currently falling. FIG. 7(b) shows the display of the rotation around the y-axis. FIG. 7(c) shows the display of the rotation around the x-axis. In this way, in this embodiment, the shake display means 10 can display the angular shake information and the translation shake information in association with information related to each of the angular shake information and the translation shake information. The shake display means 10 can also display shake direction information calculated based on the angular shake information and the translational shake information.

[0033] The camera system control unit 5 can directly use the shake correction amount for reducing the influence of shake calculated based on the respective signals output from the angular velocity detection means 15 and the acceleration detection means 16 as a shake display value. Alternatively, the camera system control unit 5 may calculate and use the shake amount for shake display. The shake information for display is calculated by a display shake information calculation means of the camera system control unit 5. Among the shake amounts for display, information on the shake amount due to angular shake is set as angular shake information, and information on the shake amount due to translational shake is set as translational shake information.

[0034] Next, the display shake information calculation means (calculation means) 100 will be described with reference to Fig. 8. Fig. 8 is a block diagram of the display shake information calculation means 100. The rotational shake compensation amount calculator 201 and the translational shake compensation amount calculator 202 calculate a shake compensation amount for reducing the influence of shake based on the respective signals output from the angular velocity detection means 15 and the acceleration detection means 16 shown in Figs. 1(a) and (b). Note that in Fig. 8, the display shake information calculation means 100, the rotational shake compensation amount calculator 201, and the translational shake compensation amount calculator 202 are part of the functions of the camera system control unit 5, but are not limited thereto.

[0035] The display method determination unit 203 determines the method of shake display. The shake display method can be determined based on a user's input, or a preset method may be used. The signal output from the display method determination unit 203 is input to converters 204 and 207. The converters 204 and 207 determine whether to convert to an angle or an image plane shake based on the signal from the display method determination unit 203. The signal from the angular shake correction amount calculator 201 is input to the converter 207.

[0036] The converter 207 converts the signal from the rotational shake compensation amount calculator 201 into an angle or image plane shake and outputs it. The signal from the rotational shake compensation amount calculator is a signal related to image plane shake, and when the dimensions of the input and output data are the same, such as when the output signal is a signal related to image plane shake, the converter 207 outputs the input signal without converting it. When an angle is input, the converter 207 converts it into an image plane shake amount by multiplying it by the focal length, and when an image plane shake amount is input, it converts it into an angle by dividing it by the focal length. Like the converter 207, the converter 204 also converts the input signal according to the output of the display method determination unit 203. The signal output from the converter 207 is input to the sensitivity adjuster 208.

[0037] The sensitivity adjuster 208 adjusts the sensitivity of the display. Here, the sensitivity of the display is the balance between the detection accuracy of the shake correction and the display accuracy of the shake display. The higher the sensitivity, the closer the display accuracy is to the detection accuracy of the shake correction, and the higher the accuracy is, but if the display is changed in small increments, it becomes difficult for the user to follow it. By adjusting the sensitivity, the display becomes easier for the user to follow.

[0038] The signal output from the converter 204 is input to the sensitivity adjuster 209. The sensitivity adjuster 209 adjusts and outputs the sensitivity. The display ratio adjuster 205 receives the signals output from the display method determination unit 203, the sensitivity adjuster 208, and the sensitivity adjuster 209. The display ratio adjuster 205 adjusts the display ratio. The display ratio is the ratio between the magnitude of the detected shake and the magnitude of the shake to be displayed, and the display ratio is set to 1 when the magnitude of the detected shake and the magnitude of the shake to be displayed are made equal. When the display method determined by the display method determination unit 203 is only the angular shake information, the display ratio of the angular shake information is set to 1 and the display ratio of the translational shake is set to 0. When the display method determined by the display method determination unit 203 is only the translational shake information, the display ratio of the translational shake information is set to 1 and the display ratio of the translational shake information is set to 0. In the case of a display method in which the display ratio is determined by the ratio between angular shake and translational shake, the display ratio adjuster 205 obtains the ratio between angular shake and translational shake, and calculates the display ratio. Depending on the adjustment of the sensitivity, it is also possible to display only the tilted direction (shake direction information). The shake display means 10 inputs the signal output from the display ratio adjuster 205, and displays shake information (for example, angular shake information, translational shake information, shake direction information, etc.). At this time, the shake display means 10 can display the angular shake information and translational shake information by multiplying them by a magnification factor.

[0039] The shake information for display may be shake compensation remaining information calculated by subtracting the correction amounts of the shake compensation means 14 and the lens driving means 13 based on the signals output from the rotational shake compensation amount calculator 201 and the translational shake compensation amount calculator 202. In this case, the shake display means 10 can display the shake compensation remaining information calculated based on the rotational shake information and the translational shake information. Displaying the shake compensation remaining information as the shake information for display is equivalent to displaying only the portion that cannot be compensated for.

[0040] Next, a method for displaying shake information (a method for controlling the imaging device 1000) will be described with reference to FIG. 9. FIG. 9 is a flowchart showing a method for displaying shake information. The flow of FIG. 9 starts at the same time as exposure starts, in accordance with an instruction from the camera system control unit 5. First, in step S1001, the shake information calculation means 100 calculates shake information (shake information for display). Step S1001 corresponds to the calculation of shake information described with reference to FIG. 8. Then, in step S1002, the shake display means 10 displays the shake information calculated in step S1001. Then, in step S1003, the camera system control unit 5 determines whether the imaging device 1000 is exposed. If it is exposed, the process returns to step S1001. On the other hand, if it is not exposed, the camera system control unit 5 ends this flow.

[0041] (Other embodiments) The present invention can also be realized by a process in which a program for implementing one or more of the functions of the above-described embodiments is supplied to a system or device via a network or a storage medium, and one or more processors in a computer of the system or device read and execute the program. The present invention can also be realized by a circuit (e.g., ASIC) that implements one or more of the functions.

[0042] According to the present embodiment, it is possible to provide an imaging apparatus, a control method, and a program that take into account shakes of different characteristics and notify a user of the state of camera shake during exposure.

[0043] Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and various modifications and changes are possible within the scope of the gist of the present invention.

[0044] For example, the display method of the angular shake information and the translational shake information in this embodiment is not limited to the display method shown in Figures 2 to 7, and other display methods may be used as long as the angular shake information and the translational shake information can be displayed separately. The shake detection means includes, but is not limited to, the angular velocity detection means 15 and the acceleration detection means 16. Although the angular velocity detection means 15 and the acceleration detection means 16 are both provided in the camera body 1, at least one of these may be provided in the lens device 2. Although the shake display means 10 and the display shake information calculation means 100 are both provided in the camera body 1, at least a part of these may be provided in the lens device 2.
