Description

  The present invention relates to a control device for an imaging device such as a camera having a camera shake correction function, and more particularly to a control device for an imaging device that performs guidance display for panning shot shooting.

  Conventionally, in order to easily perform panning, a method has been proposed in which a difference between a moving speed of a subject and a speed at which a camera is shaken is detected and the detected blur amount is corrected by a shift lens. In this method, first, immediately before shooting, while detecting the angular velocity with respect to the panning of the camera when the angular velocity sensor is tracking the subject, the amount of movement of the main subject on the imaging surface is detected at the same time, and the subject's movement is detected from the two speed information. Calculate angular velocity. During the exposure, the difference between the angular velocity of the subject obtained immediately before the exposure and the panning speed of the camera during the exposure is calculated, and correction is performed by driving the shift lens according to the difference.

  In the above correction method, it is important to accurately calculate the angular velocity of the main subject that the photographer intends to stop. That is, in order to make the main subject stand still, it is important to more accurately obtain the direction and angular velocity at which the photographer pans the camera according to the subject. As the calculated angular velocity is different from the actual angular velocity of the main subject, an error occurs during correction and appears as an unblurred image in the image.

  Patent Document 1 discloses a camera that corrects a captured image so as to approach the reference panning direction based on a difference between the actual panning direction of the camera and a preset reference panning direction, and displays the image on a monitor. Yes. Patent Document 2 discloses a camera that calculates the difference between the panning speed of the camera and the subject speed and displays whether or not blurring occurs at the time of shooting by displaying in the viewfinder.

  In panning, there are often few chances to shoot, and it is desirable to minimize the possibility of failure. However, in Patent Document 1, if there is an error between the reference panning direction and the moving direction of the subject, there is a possibility that the panning will fail. Further, in Patent Document 2, it can be confirmed that “blur residue occurs”, but “the direction and size of panning for successful panning” is not known.

  It is an object of the present invention to provide a control device and an imaging device that can improve the success rate of panning shooting.

  A control device according to one aspect of the present invention is a control device that corrects a difference between an angular velocity of an imaging device that is panning and an angular velocity of the subject by moving an optical element and tracking the moving subject. Determination means for determining whether a value based on the difference is smaller than the maximum movement amount of the optical element, and when a value based on the difference is smaller than the maximum movement amount, a distance measuring point display in the finder of the imaging device is used. When the first display is performed to display that the correction by the optical element is possible, and the value based on the difference is larger than the maximum movement amount, the panning is performed using the distance measuring point display in the finder of the imaging device. Display control means for performing a second display for displaying the correction direction and the panning correction amount.

It is stored on the memory 213. The position on the image sensor 203 corresponding to each distance measuring point display on the finder is represented by a horizontal position x [pixel] and a vertical position y [pixel] on the image sensor 203. Although simplified in FIG. 3C, it is assumed that the correspondence table has positions on the image sensor 203 for all distance measuring point displays that can be selected.

  As for the numbering method for the distance measuring point display, it is assumed that the upper left of the distance measuring point display is 1, and the number is incremented by 1 in a raster scan from there.

  Hereinafter, with reference to FIG. 4, the panning assist process executed in the camera microcomputer 201 will be described. FIG. 4 is a flowchart of the panning assist process. The panning assist process of the present embodiment is executed according to a control program as a computer program that operates on software and hardware. The control program may be stored in the memory 202, for example, or may be recorded on a computer-readable recording medium.

Moreover, a circuit corresponding to the control program of this embodiment may be provided, and the panning assist process of this embodiment may be executed by operating the circuit.

  In step S401, the camera microcomputer 201 stores, in the memory 202, a distance measurement point number selected from any distance measurement point display in the viewfinder of FIG. 3A using the operation unit 110 as a vector detection position. To do. At this time, the vector detection position on the image sensor 203 corresponding to the selected distance measuring point number can be determined using the correspondence table of FIG. The range-finding point display that can be selected as the vector detection position can select all of the arranged points regardless of the lens used and the setting at the time of shooting. In addition, when the selected ranging point display is set to the AF mode, it is used not only for determining the vector detection position but also as the AF ranging point display, and when the MF mode is set, Used only to determine the vector detection position.

  In step S <b> 402, the camera microcomputer 201 determines whether panning is detected by the angular velocity sensor 402. If panning of the imaging apparatus 100 is detected by the angular velocity sensor 402, the process proceeds to step S403, and if not detected, the loop to step S402 is repeated.

  In step S <b> 403, the camera microcomputer 201 extracts a subject at a vector detection position on the image sensor 203. In the present embodiment, an image captured by the photometric sensor 208 is input to the motion vector detection unit 111 in the APU 212, and a subject area is extracted using the obtained motion vector. Various methods such as template matching have been proposed as a method for extracting a subject area from a motion vector, and will be omitted here. If the subject cannot be extracted, the panning assist does not function because the subject angular velocity cannot be calculated. At this time, it is possible to switch to a normal photographing method that does not drive the shift lens in step S409.

  In step S <b> 404, the camera microcomputer 201 acquires angular velocity information of the imaging device 100 during panning detected by the angular velocity sensor 402.

  In step S405, the camera microcomputer 201 calculates the angular velocity of the subject. In the present embodiment, since the angular velocity of the subject is calculated using the panning angular velocity, it is calculated as an angular velocity centered on the principal point as shown in FIG.

  Hereinafter, a method for calculating the angular velocity of the subject will be described with reference to FIG. In FIG. 5, the subject moves from point A to point B for t seconds, and the subject image formed on the sensor accordingly moves from point C to point D. Here, when the distance between the point C and the point D is d [pixel], the focal length is f [mm], and the pixel pitch of the sensor is p [μm / pixel], the angular velocity ω [rad of the subject on the image plane is set. / Sec] is expressed by the following equation (1).

Here, when the imaging apparatus 100 is panned, the angular velocity ω of the subject on the image plane is determined from the angular velocity (hereinafter, subject angular velocity) ω _s of the subject as represented by the following expression (2). It is calculated by subtracting the omega _p.

Therefore, the subject angular velocity ω _s is calculated from the panning angular velocity ω _p of the imaging apparatus 100 detected by the angular velocity sensor 402 by the following equation (3).

  In step S406, the camera microcomputer 201 performs guidance display in the viewfinder at the time of panning shooting. Details of the guidance display in the finder will be described later.

  In step S407, the camera microcomputer 201 determines whether to perform an exposure operation. In this embodiment, it is determined whether or not the shutter button is fully pressed (hereinafter, SW2 is turned on). If SW2 is turned on, the process proceeds to step S408. If SW2 is not turned on, the process returns to step S403.

  In step S408, the camera microcomputer 201 controls the shutter 204 and starts shutter travel.

  In step S409, the camera microcomputer 201 operates the shift lens of the optical system 101 to assist in panning shooting.

  In step S410, the camera microcomputer 201 determines whether the set exposure time has elapsed. If the set exposure time has elapsed, the process ends. If not, the process returns to step S408.

  Hereinafter, the details of the in-finder guidance display update processing will be described with reference to FIG. FIG. 6 is a flowchart showing the in-finder guidance display update process of the present embodiment.

At step S601, the camera microcomputer 201 obtains the panning angular velocity omega _t of the imaging device 100 from the angular velocity sensor 402.

In step S602, the camera microcomputer 201 calculates a difference ω _d between the panning angular velocity ω _t acquired in step S601 and the subject angular velocity ω calculated in step S405 using the following equation (4).

In step S603, the camera microcomputer 201 determines whether it is within the correction range of the calculated difference omega _d is shot assisted step S602. Here, the maximum correction angle shot Assist (maximum travel) theta, when the exposure time is t, on whether equation (5) holds less, or within the correction range of shooting assist flow difference omega _d is Can be determined.

When the difference ω _d is within the correction range, the process proceeds to step S604, and when it is out of the correction range, the process proceeds to step S605.

  In step S604, the camera microcomputer 201 sets the guidance display mode 1. In the guidance display mode 1, in order to make the photographer recognize that the vector detection position is being determined, as shown in FIG. 7A, the distance measuring point display 702 that is the vector detection position of the display 701. Only the spot AF point display inside is lit.

  In step S605, the camera microcomputer 201 sets the guidance display mode 2. In the guidance display mode 2, as shown in FIG. 7B, the panning correction direction and the panning correction amount are displayed. A display 703 is a display when the photographer's panning is within the correction range of the panning assist, and the distance measuring point display selected as the vector detection position 704 in step S401 is lit. A display 705 is a display when the panning of the photographer is outside the panning assist correction range. At this time, the distance measuring point display selected as the vector detection position in step S401 is turned on, and the guidance display 706 using the distance measuring point display is blinked according to the panning correction direction and the panning correction amount. A method for setting the direction / size of the guidance display will be described later.

  In step S606, the camera microcomputer 201 updates the display on the display element 207 based on the display mode set in step S604 or step S605.

  Hereinafter, the process of the guidance display mode 2 will be described with reference to FIG. FIG. 8 is a flowchart showing the guidance display mode 2 process.

At step S801, the camera microcomputer 201 analyzes the difference omega _d calculated in step S602. In Equation (4), when ω _d <0, the panning angular velocity ω _t of the imaging device 100 is larger than the subject angular velocity ω, so the photographer shakes the imaging device 100 too much with respect to the subject. It can be determined that In addition, when ω _d > 0, the panning angular velocity ω _t of the imaging device 100 is smaller than the subject angular velocity ω, and thus the photographer is behind the imaging device 100 with respect to the subject. I can judge. In the present embodiment, the above two states are distinguished by setting the swing delay flag to 0 or 1, and stored in the memory 202. Specifically, when ω _d <0, the swing delay flag is set to 0, and when ω _d > 0, the swing delay flag is set to 1. Further, the swing delay flag is prepared for each of the horizontal direction and the vertical direction and stored in the memory 202.

In step S802, the camera microcomputer 201 uses the horizontal component ω _dx obtained as a result of the analysis in step S801 to determine whether or not the photographer is behind the imaging device 100 in the horizontal direction. In the present embodiment, when ω _dx > 0, that is, when the photographer is behind the imaging apparatus 100 with respect to the subject angular velocity, the process proceeds to step S803, and ω _dx <0, that is, the photographer is not subject to the subject angular velocity. When the imaging device 100 is shaken too much, the process proceeds to step S804.

  In step S <b> 803, the camera microcomputer 201 sets a swing delay flag with respect to the horizontal direction to 1 and stores it in the memory 202.

  In step S <b> 804, the camera microcomputer 201 sets a swing delay flag with respect to the horizontal direction to 0 and stores it in the memory 202.

In step S805, the camera microcomputer 201 uses the vertical component ω _dy obtained as a result of the analysis in step S801 to determine whether the photographer has delayed the imaging device 100 in the vertical direction. In the present embodiment, if ω _dy > 0, that is, if the photographer is behind the imaging apparatus 100 with respect to the subject angular velocity, the process proceeds to step S806, and ω _dy <0, that is, the photographer is not subject to the subject angular velocity. When the imaging device 100 is shaken too much, the process proceeds to step S807.

  In step S806, the camera microcomputer 201 sets the swing delay flag for the vertical direction to 1 and stores it in the memory 202.

  In step S <b> 807, the camera microcomputer 201 sets the swing delay flag with respect to the vertical direction to 0 and stores it in the memory 202.

In step S808, the camera microcomputer 201 determines the number of distance measuring point displays to be displayed in the horizontal direction. The angle amount θ _dx exceeding the correction range of the panning assist is expressed by the following equation (6) using the horizontal component ω _dx and the exposure time t used in step S802.

At this time, the angle amount θ _dx , the horizontal direction component θ _x of the maximum correction angle θ of the panning assist, and the number k of distance measuring point displays to be displayed satisfy the following formula (7).

  The camera microcomputer 201 determines the maximum positive integer k that satisfies Expression (7) as the number of focus detection points displayed in the vertical direction and stores it in the memory 202.

In step S809, the camera microcomputer 201 determines the number of distance measuring point displays to be displayed in the vertical direction. The angle amount θ _dy that exceeds the correction range of the panning assist is expressed by the following equation (8) using the vertical direction component ω _dy and the exposure time t used in step S802.

At this time, the angle amount θ _dy , the vertical direction component θ _y of the maximum correction angle θ of the panning assist, and the number l of distance measuring point displays to be displayed satisfy the following formula (9).

  The camera microcomputer 201 determines the maximum positive integer l satisfying Expression (9) as the number of focus detection points displayed in the vertical direction and stores it in the memory 202.

  In step S902, the camera microcomputer 201 determines whether or not the swing delay flag with respect to the horizontal direction referred to in step S901 is 1. If the flag is 1, that is, if the photographer is behind the imaging device 100 with respect to the subject angular velocity, the process proceeds to step S903, and the flag is 0, that is, if the photographer is shaking the imaging device 100 too much with respect to the subject angular velocity. The process proceeds to step S904.

  In step S <b> 903, the camera microcomputer 201 performs a guidance display that makes the photographer shake the imaging device 100 more. First, the camera microcomputer 201 reads the distance measuring point number selected in step S401 from the memory 202 and turns on the corresponding distance measuring point display. Next, the angular velocity sensor 402 determines whether the horizontal direction of panning is the + direction or the − direction. For example, assume that the distance measuring point number selected in step S401 is 23, the panning horizontal direction is the + direction in FIG. 3A, and the number of distance measuring point displays determined in step S808 is two. In this case, as shown in FIG. 10A, since the number of distance measuring points to be blinked is two in the + direction from 23, the distance measuring point numbers 24 and 25 are obtained from the distance measuring point number array, and measurement is performed.

For example, it is assumed that the distance measuring point number selected in step S401 is 23, the horizontal direction of panning is the + direction in FIG. 3A, and the number of displays determined in step S808 is two. In this case, as shown in FIG. 10 (b), since the number of distance measuring points to be blinked is two in the minus direction from 23, the distance measuring point numbers 22 and 21 are obtained from the distance measuring point number array, and measurement is performed.
