Description

The present invention relates to a camera system, and more particularly to a camera system capable of live view display.

 With a compact digital camera with a built-in lens, as the multi-function and high image quality progress, like the optical viewfinder, you want to perform operations such as visual angle of view at the time of shooting and delicate focus adjustment on the display device. In response to demands, digital cameras having a through image display (hereinafter, live view) function for displaying an image formed on an image sensor as a moving image image on a liquid crystal monitor or the like have become widespread. In recent years, not only compact digital cameras but also interchangeable lens digital reflex cameras have been equipped with this live view function.

 The live view function is normally operated, for example, as shown in FIG. 7, when the digital camera 100 is intended to photograph the subject 200, the digital camera 100 performs pixel thinning or pixel addition at regular intervals from the image sensor. In order to determine the angle of view and the like in photographing by reading out the charges while performing the process, the display is finally displayed on the liquid crystal monitor 101 or the like as shown in FIG.

 In a digital camera equipped with such a live view function, if it is possible for a user or a manual focus to be focused more accurately, for example, a liquid crystal monitor 101 disclosed in Patent Document 1 is used. An increasing number of models are further equipped with a function for enlarging the displayed live view display. This is because, as shown in FIG. 8A, the user selects a portion (a portion of the enlarged display frame 102) that he / she wants to enlarge by manual operation, so that the portion of the enlarged display frame 102 as shown in FIG. Is enlarged and displayed on the entire screen of the liquid crystal monitor 101 or the like.

JP-A-5-244471

However, if the live view display is enlarged as shown in FIG. 8B, there is a problem that the amount of blur on the display screen with respect to the amount of focus movement becomes easier to see.

Here, the principle of blur difference depending on display magnification will be described.

The formula for calculating the depth of focus (φ) is
φ = K × F × δ
Obtained from Here, F is the F number of the lens, δ is the allowable circle of confusion, and K is a coefficient.

In the case of the entire display as shown in FIG. 8A, the allowable circle of confusion allowable as blur is a resolution corresponding to the number of pixels of the display device such as the liquid crystal monitor 101, and therefore the allowable circle of confusion is large. Since the depth of focus becomes deep, the user cannot determine the blur change even if the focus movement amount is large. On the other hand, in the case of enlarged display as shown in FIG. 8B (particularly when displaying an imager region having the same number of pixels as the number of pixels of the display device), the permissible circle of confusion is the pixel pitch of the imager. The depth becomes shallower, and the blur can be seen even with a slight focus shift.

Therefore, in a digital camera capable of manual focus adjustment, fineness is required for the manual focus operation for enlarged display. In particular, an interchangeable-lens digital camera has a larger imaging device than a compact camera and can select a lens with a small lens F value. Therefore, the depth of focus tends to be shallow, and the requirement is further severe.

 Further, when the live view display is enlarged as shown in FIG. 8B, in a digital camera having a camera shake correction function, the shake amount on the display screen with respect to the drive amount of the camera shake correction becomes easier to see. The problem also occurs.

Here, the principle of the difference in camera shake amount depending on the display magnification will be described.

In the case of the whole display as shown in FIG. 8A, since the resolution is in accordance with the number of pixels of the display device, the permissible circle of confusion is large and there is no movement in the X-Y direction beyond the permissible circle of confusion. The movement is not reflected in the display image. On the other hand, in the case of enlarged display as shown in FIG. 8B (particularly when displaying an imager region having the same number of pixels as the display device), the permissible circle of confusion is the pixel pitch of the imager. Even in the XY movement, it can be seen that it is moving on the display screen.

 The present invention has been made in view of the above points, and an object of the present invention is to provide a camera system capable of solving the problem when the live view display is enlarged and displayed.

In order to achieve the above object, the first aspect of the present invention provides:

[First Embodiment]
The first embodiment is intended to provide a digital camera that can be easily focused manually even when the live view display is enlarged.

As shown in FIG. 1, the digital camera according to the first embodiment is an interchangeable lens digital camera including a body unit 10 and a lens unit 20.

The lens unit 20 is provided as an interchangeable lens configured to be detachable from the body unit 10, and includes a focus lens 21, a focus drive unit 22, a focus ring 23, a focus ring rotation detection unit 24, and a lens. A CPU 25, a communication unit 26, and the like are provided.

 Here, the focus lens 21 is a photographing optical system that forms an image of a light beam from a subject, and can be adjusted in focus by being driven in the optical axis direction by a focus driving unit 22. In a digital camera, this focus adjustment is automatically performed by an auto focus (AF) function, but there is a model in which the user can adjust the focus manually. The focus ring 23 is a user operation member for that purpose. The focus ring 23 is an operation member that can be rotated by the user. The focus ring 23 indicates the drive direction of the focus lens 21 by the rotation direction, and indicates the drive amount of the focus lens 21 by the rotation speed or rotation angle. It is configured. The focus ring rotation detection unit 24 detects the rotation direction and rotation speed or rotation angle of the focus ring 23 and inputs the detection result to the lens CPU 25. The lens CPU 25 communicates with the body unit 10 via the communication unit 26 to control each unit in the lens unit 20, and the focus driving unit according to the detection result from the focus ring rotation detection unit 24. 22 is provided with a function of adjusting the focus position of the focus lens 21 by giving a drive instruction to the lens 22. In addition, for AF, a function of transmitting a detection result of a focus encoder (not shown) that detects the focus position of the focus lens 21 to the body unit 10 via the communication unit 26 is also provided.

 On the other hand, the body unit 10 includes a camera CPU 11, an image sensor 12, an image processing circuit 13, a display circuit 14, a display unit 15, a display magnification instruction unit 16, an MF / AF instruction unit 17, a communication unit 18, and the like.

Here, the camera CPU 11 controls each part in the body part 10. The image sensor 12 receives the subject light transmitted through the focus lens 21 and photoelectrically converts the subject image into a video signal under the control of the camera CPU 11. Under the control of the camera CPU 11, the image processing circuit 13 reads out charges while performing pixel thinning or pixel addition at regular intervals from the image sensor 12 to generate an image signal, and performs gain control or sample hold control. After performing the above-described processes, A / D conversion is performed and output. The display circuit 14 includes a memory for storing the A / D-converted image signal, reads the image signal stored in the memory under the control of the camera CPU 11, performs D / A conversion, and performs liquid crystal display. By displaying on the display unit 15 such as a monitor, live view display is performed.

 The display magnification instruction unit 16 is an operation member for instructing the magnification of the live view display and a portion to be enlarged. This may be provided as a dedicated operation button or displaying a hierarchical menu on the display unit 15. , It may be in a form of selecting from among them.

 The camera CPU 11 controls the image processing circuit 13 or the display circuit 14 to display an image of a portion designated by the user at a magnification designated by the user by the display magnification instruction unit 16. For example, when the enlargement display method is a digital enlargement method in which only the display is changed, the display circuit 14 is controlled so as to continuously read out the pixels in the enlarged portion a plurality of times. Further, when the enlargement display method is an enlargement method in which the readout method of the image sensor 12 is changed, the image processing circuit 13 is controlled so as to perform the same-size pixel readout that reads the charge of the pixel of the enlarged portion from the image sensor 12 as it is. To do. Further, the camera CPU 11 transmits the display magnification information of the magnification designated by the user by the display magnification instruction unit 16 to the lens unit 20 via the communication unit 18.

 The MF / AF instruction unit 17 is an operation member for instructing switching between manual focus (MF) and AF, and may be provided as a dedicated operation button, or may display a hierarchical menu on the display unit 15. In such a case, it is possible to select one of them.

 The camera CPU 11 controls the start / stop of the AF function in accordance with a user instruction from the MF / AF instruction unit 17, and sends AF / MF information indicating the instruction content by the MF / AF instruction unit 17 to the lens via the communication unit 18. To the unit 20.

 The lens CPU 25 of the lens unit 20 receives the display magnification information and the AF / MF information from the body unit 10 via the communication unit 26, and changes the focus lens driving sensitivity according to them, as will be described in detail later.

 When a shooting request is made by operating the release button, the image processing circuit 13 reads out all charges from the image pickup device 12 at the same pixel magnification and generates an image signal under the control of the camera CPU 11. After performing processing such as gain control and sample hold control, A / D conversion is performed and output. Then, the A / D converted image signal is subjected to a predetermined compression process such as JPEG under the control of the camera CPU 11 by a compression / decompression circuit (not shown), so that it can be incorporated in or removed from the body unit 10. Recorded in the illustrated recording memory.

 Next, the focus lens drive sensitivity changing operation in the camera CPU 11 and the lens CPU 25 of the digital camera configured as described above will be described with reference to the flowchart shown in FIG.

 The camera CPU 11 first reads the instruction state of the MF / AF instruction unit 17 (step S11) and determines whether AF / MF has been changed (step S12). Here, if it has been changed, AF / MF information indicating the content of the instruction from the MF / AF instruction unit 17 is transmitted to the lens unit 20 via the communication unit 18 (step S13).

 After that, or when it is determined in step S12 that there is no change, the instruction content of the display magnification instruction unit 16 is further read (step S14), and it is determined whether or not the display magnification has been changed (step S15). Here, if it has been changed, the display magnification information indicating the instruction content by the display magnification instruction unit 16 is transmitted to the lens unit 20 via the communication unit 18 (step S16).

 Thereafter, or if it is determined in step S15 that there is no change, the process returns to step S11.

 On the other hand, the lens CPU 25 is waiting for a communication request from the body unit 10 via the communication unit 26 (step S21), and when receiving the communication request, acquires information from the body unit 10 via the communication unit 26. (Step S22). The information in this case is the AF / MF information transmitted by the camera CPU 11 in step S13 or the display magnification information transmitted in step S16, and the lens CPU 25 stores the contents in an internal memory (not shown).

 Thereafter, it is determined whether or not the current MF mode is set based on the information stored in the internal memory (step S23). If the AF mode is selected instead of the MF mode, the process returns to step S21.

 On the other hand, in the MF mode, it is further determined whether or not an enlargement display is currently instructed based on the information stored in the internal memory (step S24). Here, when the enlarged display is not instructed, that is, when the entire display is instructed, the focus lens drive sensitivity is set to the standard (step S25), and the process returns to step S21. If enlargement display is instructed, the focus lens drive sensitivity is lowered (step S26), and the process returns to step S21.

 Here, reducing the focus lens drive sensitivity means, for example, reducing the drive amount of the focus lens 21 with respect to the rotation angle of the focus ring 23 as shown in FIG. That is, even if the rotation angle of the focus ring 23 per unit time is the same, the driving amount of the focus lens 21 is made smaller than that in the case of the entire display.

 Furthermore, at the time of enlarged display, it is preferable that the minimum detection amount of the rotation angle of the focus ring 23 is made small so that the driving can be performed smaller than at the time of the entire display.

 Also, the amount of change in sensitivity can be set to a value corresponding to the F-No of the lens, the focal length, and the focus position.

 Furthermore, the value may be changed depending on whether the enlargement method is a digital enlargement method in which only display is changed or an enlargement method in which the reading method from the image sensor 12 is changed. In this case, it is assumed that the camera CPU 11 communicates with the lens CPU 25 to determine which method is the enlargement method.

 The lens CPU 25 includes a memory that stores the relationship of the graph of FIG. 3 during full display and enlarged display as a table, and the sensitivity may be changed by switching the table to be used, or driven by an arithmetic expression. If it is the structure which calculates quantity, what is necessary is just to make it change sensitivity by switching the arithmetic expression to be used.

 As described above, according to the first embodiment, the focus ring 23 that is an operation member that can be rotated by the user, the rotation speed or the rotation angle, and the rotation direction of the focus ring 23 are detected, and the detection result The focus ring rotation detection unit 24, the lens CPU 25, and the focus driving unit 22 that function as a focus lens drive control unit that controls the drive of the focus lens 21 according to the above, and a display magnification instruction that functions as an instruction unit that instructs to change the live view display magnification In the digital camera having the live view display having the unit 16, the driving sensitivity of the focus lens 21 is changed in accordance with the live view display magnification change instruction by the display magnification instruction unit 16. It becomes possible to solve the problem when the display is enlarged. .

 In particular, when performing manual focus during live view display, changing the drive sensitivity of the focus lens 21 according to the operation of the focus ring 23 according to the display magnification makes it possible to easily perform subtle manual focusing even during live view display. Will be able to supply a manual focus system.

 That is, at the time of live view enlargement display, the focus lens 21 does not move so much even if the focus ring 23 is moved greatly by reducing the drive sensitivity of the focus lens 21, so that the fineness required for the manual focus operation is reduced. Therefore, it is particularly suitable for an interchangeable lens digital camera that can select a large image sensor and a small lens F value.

 Further, by reducing the minimum detection amount of the rotation angle of the focus ring 23 during live view enlargement display, the focus lens 21 can be made minute even by a slight operation of the focus ring 23 so that the focus lens 21 is not moved during live view entire display. Since the amount can be moved, more delicate focusing can be performed.

 The MF / AF instruction unit 17 may be provided on the lens unit 20 side instead of the body unit 10 side. In that case, the state of the MF / AF instruction unit 17 may be detected by the lens CPU 25 and communicated to the camera CPU 11 of the body unit 10 by the communication unit 26.

 Similarly, the display magnification instruction unit 16 may be provided on the lens unit 20 side instead of the body unit 10 side. In this case, the state of the display magnification instruction unit 16 may be detected by the lens CPU 25 and communicated to the camera CPU 11 of the body unit 10 by the communication unit 26.

[Second Embodiment]
The second embodiment is intended to provide a digital camera capable of suppressing the influence of appearance even when camera shake correction is performed when the live view display is enlarged.

 As shown in FIG. 4, the digital camera according to the second embodiment is an interchangeable lens digital camera including a body unit 10 and a lens unit 20.

 The lens unit 20 is provided as an interchangeable lens configured to be detachable from the body unit 10, and includes a focus lens 21, a lens CPU 25, a communication unit 26, a camera shake detection unit 27, a camera shake drive unit 28, and the like. Is provided.

 Here, the focus lens 21 is a photographing optical system that forms an image of a light beam from a subject. The camera shake detection unit 27 detects a camera shake state of the digital camera using, for example, an acceleration sensor or an angular velocity sensor, and inputs the detection result to the lens CPU 25. The camera shake driving unit 28 optically corrects camera shake, for example, by moving the focus lens 21 in a direction that cancels camera shake. The lens CPU 25 communicates with the body unit 10 via the communication unit 26 to control each unit in the lens unit 20, and to the camera shake driving unit 28 according to the detection result from the camera shake detection unit 27. It has a function of correcting camera shake by giving a drive instruction. In addition, for AF, a function of transmitting a detection result of a focus encoder (not shown) that detects the focus position of the focus lens 21 to the body unit 10 via the communication unit 26 is also provided.

On the other hand, the body unit 10 includes a camera CPU 11, an imaging device 12, an image processing circuit 13, a display circuit 14, a display unit 15, a display magnification instruction unit 16, a communication unit 18, a camera shake correction instruction unit 19, and the like.

Here, the camera CPU 11 controls each part in the body part 10. The image sensor 12, the image processing circuit 13, the display circuit 14, the display unit 15, the display magnification instruction unit 16, and the communication unit 18 are the same as those described in the first embodiment, and thus description thereof is omitted.

 The camera shake correction instruction unit 19 is an operation member for instructing whether or not to perform camera shake correction. This may be provided as a dedicated operation button, or a hierarchical menu is displayed on the display unit 15, It is possible to select from the following. The camera CPU 11 transmits camera shake correction information indicating the instruction content by the camera shake correction instruction unit 19 to the lens unit 20 via the communication unit 18.

 The lens CPU 25 of the lens unit 20 receives the display magnification information and the camera shake correction information from the body unit 10 via the communication unit 26, and changes the camera shake correction sensitivity according to them as follows.

Here, the camera shake correction sensitivity changing operation in the camera CPU 11 and the lens CPU 25 of the digital camera configured as described above will be described with reference to the flowchart shown in FIG.

The camera CPU 11 first reads the instruction state of the camera shake correction instruction unit 19 (step S17), and determines whether or not the camera shake correction has been changed (step S18). Here, if it has been changed, the camera shake correction information indicating the instruction content by the camera shake correction instruction unit 19 is transmitted to the lens unit 20 via the communication unit 18 (step S19).

 Thereafter, or when it is determined in step S18 that there has been no change, the instruction content of the display magnification instruction unit 16 is further read (step S14), and it is determined whether or not the display magnification has been changed (step S15). Here, if it has been changed, the display magnification information indicating the instruction content by the display magnification instruction unit 16 is transmitted to the lens unit 20 via the communication unit 18 (step S16).

Thereafter, or if it is determined in step S15 that there is no change, the process returns to step S11.

On the other hand, the lens CPU 25 is waiting for a communication request from the body unit 10 via the communication unit 26 (step S21), and when receiving the communication request, acquires information from the body unit 10 via the communication unit 26. (Step S22). The information in this case is the camera shake correction information transmitted by the camera CPU 11 in step S19 or the display magnification information transmitted in step S16, and the lens CPU 25 stores the contents in an internal memory (not shown).

Thereafter, based on the information stored in the internal memory, it is determined whether or not the current mode is the camera shake correction mode (step S27). If not, the process returns to step S21.

On the other hand, if it is the camera shake correction mode, it is further determined whether or not enlargement display is currently instructed based on the information stored in the internal memory (step S28). Here, when the enlarged display is not instructed, that is, when the entire display is instructed, the camera shake correction sensitivity is set to the standard (step S29), and the process returns to step S21. If enlargement display is instructed, the camera shake correction sensitivity is increased (step S30), and the process returns to step S21.

 Here, increasing the camera shake correction sensitivity means, for example, as shown in FIG. 6, reducing the minimum camera shake detection amount so that the camera shake correction drive can be performed even with a camera shake amount smaller than that during the entire display.

The amount for changing the sensitivity can be set to a value corresponding to the F-No of the lens, the focal length, and the focus position.

Furthermore, the value may be changed depending on whether the enlargement method is a digital enlargement method in which only display is changed or an enlargement method in which the reading method from the image sensor 12 is changed. In this case, it is assumed that the camera CPU 11 communicates with the lens CPU 25 to determine which method is the enlargement method.

 The lens CPU 25 includes a memory that stores the relationship of the graph of FIG. 6 at the time of the entire display and the enlarged display as a table, and the sensitivity may be changed by switching the table to be used, or driven by an arithmetic expression. If it is the structure which calculates quantity, what is necessary is just to make it change sensitivity by switching the arithmetic expression to be used.

 As described above, according to the second embodiment, the lens CPU 25 and the camera shake driving unit 28 that function as a camera shake correction unit that optically corrects the camera shake, and an instruction unit that instructs to change the live view display magnification. In the digital camera capable of live view display having the display magnification instruction unit 16, the camera shake correction sensitivity is changed in accordance with the live view display magnification change instruction by the display magnification instruction unit 16. It is possible to provide a digital camera that can solve the problem when the display is enlarged.

In particular, when performing camera shake correction during live view display, it is possible to provide a screen display that does not fail even when live view is enlarged by changing the camera shake correction amount in accordance with the display magnification.

In other words, during live view enlargement display, camera shake correction can be performed by increasing the camera shake correction sensitivity, so that even a slight movement in the XY direction can be seen moving on the display screen. Things will disappear.

Note that the display magnification instruction unit 16 may be provided on the lens unit 20 side instead of the body unit 10 side. In this case, the state of the display magnification instruction unit 16 may be detected by the lens CPU 25 and communicated to the camera CPU 11 of the body unit 10 by the communication unit 26.

The camera shake correction instruction unit 19 may also be provided on the lens unit 20 side instead of the body unit 10 side. In this case, the state of the camera shake correction instruction unit 19 may be detected by the lens CPU 25.

Further, the camera shake detection unit 27 may be provided not on the lens unit 20 side but on the body unit 10 side. In that case, the state of the camera shake detection unit 27 may be detected by the camera CPU 11 and communicated to the lens CPU 25 of the lens unit 20 by the communication unit 18. When the camera shake detection unit 27 is provided on the body unit 10 side, it is possible to adopt a method of detecting camera shake by detecting image blur from an image captured by the image sensor 12.

Further, the camera shake driving unit 28 may be provided not on the lens unit 20 side but on the body unit 10 side. In that case, it is good also as a structure which communicates the drive information by the sensitivity switched from the lens CPU25 to the body part 10 by the communication part 18, or communicates camera-shake detection amount information from the lens CPU25 to the body part 10 by the communication part 18. The camera shake correction sensitivity may be switched by the camera CPU 11. Alternatively, the camera shake detection unit 27 may be provided on the body unit 10 side, and the camera CPU 11 may switch the camera shake correction sensitivity.

 Although the present invention has been described above based on the embodiments, the present invention is not limited to the above-described embodiments, and various modifications and applications are naturally possible within the scope of the gist of the present invention.

 For example, the first embodiment and the second embodiment may be combined to switch both the focus lens driving sensitivity and the camera shake correction sensitivity according to the magnification of the live view display.

 Moreover, although the said 1st and 2nd embodiment demonstrated the lens interchangeable digital camera to the example, it is needless to say that it is applicable also to lens integrated digital cameras, such as a compact camera.
