Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that, since cutout of an angle of view in the case of performing an electronic zoom is not performed by neither an subject nor the position of a ranging frame, when the angle of view to the subject shifts or the ranging frame is fixed in the center to the angle of view or the ranging frame is not moved, the ranging frame is deviated from the object. <P>SOLUTION: A feature extractor 77 and an AF part 78 perform a focus control based on an imaging picture 6a in the ranging frame. A cutout part 75 and an enlarging/contracting part 76 performs the electronic zoom by cutting out the partial angle of view of the imaging picture 6a. On this occasion, the cutout part 75 determines the angle of view to be cut out based on the position of the ranging frame. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to an imaging apparatus and a control method therefor, for example, an imaging apparatus such as an electronic camera with a monitor and a camera-integrated video recorder that can view a captured image or a reproduced image on a liquid crystal monitor.

  FIG. 17 is a diagram illustrating a configuration for realizing electronic zoom.

  The video signal photoelectrically converted by the imaging unit 21 such as a CCD is subjected to signal processing such as CDS and AGC by the analog signal processing circuit 22 and converted into image data by the A / D converter 23. The digital signal processing circuit 24 having a memory stores image data for each field or frame in the memory. The image enlargement interpolation circuit 25 reads image data from the memory according to the zoom ratio, and performs interpolation between pixels and lines. Image data output from the image enlargement interpolation circuit 25 is converted to an analog signal by the D / A converter 26 and output to the video signal output terminal 27. With such a configuration, as will be described in detail later, an electronic zoom as shown in FIG. 7 is realized.

  However, in the conventional electronic camera having the electronic zoom configuration shown in FIG. 17, when the electronic zoom is performed, the angle of view is cut out regardless of the position of the subject or the distance measurement frame, as shown in FIG. (See, for example, JP-A-6-086130). In other words, the angle of view when the electronic zoom is performed by a conventional electronic camera or the like is not performed depending on the position of the subject or the distance measurement frame. On the other hand, there is a problem that the distance measurement frame is shifted from the subject when the distance measurement frame is fixed to the center or the distance measurement frame is not moved.

JP-A-6-086130

  An object of the present invention is to provide an electronic zoom that maintains the relative position of a subject with respect to an angle of view.

  The present invention has the following configuration as one means for achieving the above object.

  An imaging apparatus according to the present invention is an imaging apparatus that photoelectrically converts a subject image, performs image processing on an image obtained by the photoelectric conversion, and stores the image in a display and storage medium. Focus control means for controlling, zooming means for executing electronic zoom by cutting out a partial angle of view of the image, setting means for setting the position of the distance measurement frame and the magnification of the electronic zoom, and the distance measurement And determining means for determining the angle of view to be cut out based on the position of the frame.

  A control method according to the present invention is a method for controlling an imaging apparatus that photoelectrically converts a subject image, performs image processing on an image obtained by the photoelectric conversion, and stores the image in a display and storage medium. In order to execute the electronic zoom by performing focus control based on the image and cutting out a partial angle of view of the image, the position of the distance measurement frame and the magnification of the electronic zoom are set, and the position of the distance measurement frame is determined based on the position of the distance measurement frame. Further, the angle of view to be cut out is determined.

  According to the present invention, it is possible to provide an electronic zoom that maintains the relative position of a subject with respect to an angle of view, and it is possible to solve problems such as a shift of the angle of view with respect to the subject and a distance measurement frame from the subject. As a result, for example, in the case of a composition in which a subject is captured at a golden ratio with respect to the angle of view, electronic zoom can be performed while maintaining the composition. Further, since the electronic zoom can be performed without shifting the distance measuring frame from the subject, the focused state with respect to the subject can be maintained.

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

[Device configuration]
FIG. 1 is a block diagram illustrating a configuration example of the imaging apparatus according to the embodiment.

  The CPU 1 executes a program on the memory 2 composed of RAM, ROM, etc., thereby displaying the display unit 3, the operation unit 4, the communication unit 5, the imaging unit 6, the image processing unit 7, the storage medium drive 8, and the compression Predetermined control necessary for the photographing operation of the processing unit 9 is performed. Note that the memory 2 holds a program executed by the CPU 1 and data necessary for program execution.

  The display unit 3 is a display device such as a liquid crystal display (LCD) used for operation menu display such as display of an electronic viewfinder (EVF) image, reproduction display of a captured image, and setting of various shooting conditions.

  The operation unit 4 includes buttons, a cross key, a dial, and the like that are operated by a photographer (user) to set various shooting conditions and perform shooting operations.

  The communication unit 5 is connected to an external device provided with a communication means such as a personal computer (PC), another imaging device, or a printer, and transmits / receives captured images, transmits / receives information such as shooting conditions, and controls the external device. Command transmission, and reception of a command for the external apparatus to control the imaging apparatus.

  The imaging unit 6 converts an optical image of a subject into a video signal using an imaging system such as an optical system using a lens and a charge coupled device (CCD), and transmits the video signal to the image processing unit 7. Further, the imaging unit 6 includes a shutter mechanism and a diaphragm mechanism, and adjusts the amount of photographing light.

  The image processing unit 7 performs auto focus (AF) processing, auto exposure (AE) processing, auto white balance (AWB) processing, and the like by performing predetermined signal processing on the video signal obtained from the imaging unit 6. The image processing unit 7 sets a rectangular area having image data received from the imaging unit 6 as a distance measurement frame, and performs AF processing based on image information in the distance measurement frame. In addition, at the time of electronic zoom, an arbitrary rectangular area is cut out by setting a view angle cutout position. Further, the cut-out rectangular image is enlarged or reduced in accordance with EVF display, review display, or shooting size.

  The compression processing unit 9 performs data compression processing on the image data after the image processing by the image processing unit 7.

  The storage medium drive 8 stores the image data compressed by the compression processing unit 9 and various information at the time of shooting as a data file in the storage medium. As the storage medium, a solid-state memory such as a semiconductor, a hard disk, an optical storage medium, or the like can be used.

[Image processing]
FIG. 2 is a diagram showing a data flow of image processing for realizing ranging, AF processing, and electronic zoom.

  The captured image data 69 output from the imaging unit 6 is input to the cutout unit 75 and the feature extraction unit 77 of the image processing unit 7. Distance extraction frame information 41 (information indicating the position and size of the distance measurement frame with respect to the image) designated by the user is input in advance from the operation unit 4 to the feature extraction unit 77, and feature extraction is performed based on this information. The unit 77 extracts image features. The feature information extracted by the feature extraction unit 77 is input to an autofocus (AF) unit 78, and the AF unit 78 performs AF processing based on the feature information.

  On the other hand, the cutout unit 75 determines the cutout information 42 (information indicating the cutout position and size of the angle of view with respect to the image) according to the electronic zoom magnification 40 specified by the user from the operation unit 4, and this cutout Based on the information 42, the cutout unit 75 cuts out the angle of view. The image data cut out by the cutout unit 75 is input to the enlargement / reduction unit 76, subjected to enlargement / reduction processing to a desired display size, and then stored in the memory 2 as display image data 22. The display unit 3 reads the display image data 22 from the memory 2 and displays it.

  An image obtained by the imaging unit 6 by such a series of image processing is displayed on the display unit 3 as an electronic zoomed image, and at that time, AF processing is performed.

[Cutting out the angle of view]
FIG. 3 is a diagram for explaining a method for determining the cutout information 42 by the cutout unit 75. Reference numeral 301 denotes an angle of view before electronic zoom, and reference numeral 302 denotes an angle of view after electronic zoom.

When the electronic zoom is designated, the clipping unit 75 determines the angle of view to be clipped so that the relative position of the center of gravity 303 of the subject is always constant with respect to the angles of view 301 and 302 regardless of the zoom magnification. . That is, the cutout information 42 is determined so that the formula (1) holds.
W / W '= H / H' (1)

  As a result, the relative position of the center of gravity of the main subject with respect to the angle of view is always maintained during electronic zoom.

  FIG. 4 is a diagram showing the relationship between the angle of view 401, the distance measurement frame 402, and the center of gravity 403 of the main subject.

  The feature extraction unit 77 extracts image features from the image information in the distance measurement frame 402 indicated by the distance measurement frame information 41, and the AF unit 78 performs AF processing for detecting the distance to the subject based on the extracted features. Do. The ranging frame 402 can be moved to an arbitrary position with respect to the angle of view by the user. In the case of an imaging apparatus having a function of automatically following a subject, the position of the distance measuring frame 402 is determined by the function. For example, when there is one distance measuring frame 42, the center 403 of the main subject is the center of the distance measuring frame (the geometric center of gravity of the distance measuring frame).

  FIG. 5 is a diagram showing the relationship between the angle of view and the distance measurement frame before and after the electronic zoom. Reference numerals 501 and 504 indicate the angle of view and the distance measurement frame before the electronic zoom, and reference numerals 502 and 505 indicate the angle of view and the measurement distance after the electronic zoom. Represents a range frame. Assume that the distance measurement frame 504 captures the main subject 503 before the electronic zoom.

  As shown in FIG. 5, since the imaging apparatus of the present embodiment maintains the relative position of the center of gravity of the main subject 503 with respect to the angle of view, the center of the distance measurement frame 505 after the electronic zoom is the distance measurement before the electronic zoom. The captured image 69 output from the imaging unit 6 does not move from the center of the frame 504, and does not deviate from the main subject 503. The user can also observe the EVF image displayed on the display unit 3 and change the size of the distance measurement frame before and after the electronic zoom so that the sizes of the distance measurement frames 504 and 505 are equal.

  FIG. 6 is a flowchart showing the determination process of the cutting information 42 by the cutting unit 75, which is a process that is started when the user operates the electronic zoom by the operation unit 4.

  First, the center of gravity 303 of the main subject 503 is obtained (S1). When there is one distance measuring frame, the center of the distance measuring frame 504 before the electronic zoom is the center of gravity.

  Next, a field angle cutout position corresponding to the electronic zoom magnification is obtained, and the field angle is cut out (S2). The cut-out position of the angle of view is a position where the relative position of the center of gravity 303 of the main subject 503 with respect to the angle of view does not change. The cut-out size of the angle of view is determined by the electronic zoom magnification.

  Then, the distance measuring frame 505 is arranged on the angle of view after the electronic zoom (S3). For example, it seems that the size of the distance measurement frame does not change with respect to the angle of view. The position of the distance measurement frame does not change apparently because the relative position with respect to the angle of view is constant.

  FIG. 7 and FIG. 8 show how the relationship between the angle of view during electronic zoom and the center of gravity 303 of the main subject 503 is obtained by the above-described series of processing.

  FIG. 7 shows a case where the center of gravity 303 of the main subject 503 is centered with respect to the angle of view. In this case, the cut-out angle of view changes as indicated by reference numerals 701, 702, and 703 as it is enlarged by electronic zoom.

  FIG. 8 shows a case where the center of gravity 303 of the main subject 503 is located on the lower left side with respect to the angle of view. In this case, the cut-out angle of view changes as indicated by reference numerals 801, 802, and 803 as it is enlarged by electronic zoom.

  FIG. 9 is a diagram showing the relationship between the angle of view and the distance measurement frame before and after the conventional electronic zoom. Reference numerals 901 and 904 indicate the angle of view and the distance measurement frame before the electronic zoom, and reference numerals 902 and 905 indicate the angle of view after the electronic zoom. It is assumed that the distance measurement frame represents a main subject 503 before the electronic zoom.

  As shown in FIG. 9, regardless of the position of the main subject 503 and the position of the distance measurement frame, if the angle of view is always cut out based on the electronic zoom magnification with the center of the angle of view as the center of the electronic zoom, the distance measurement frame The position of the main subject 503, which will be present at the position, moves relative to the angle of view. For this reason, there is a problem that even if the user determines the composition of the main subject 503 while paying attention to the golden ratio or the like, if the electronic zoom is performed, the golden ratio is lost.

  Further, if the user's apparent range-finding frame position is maintained, there is a problem that the user is displaced from the subject.

  Further, if the distance measurement frame is not shifted from the subject, there is a problem that the apparent distance measurement frame position of the user moves.

  On the other hand, as shown in FIG. 5, the image pickup apparatus according to the embodiment maintains the relative position of the center of gravity 303 of the main subject 503 with respect to the view angles 501 and 502, so that the distance measurement frame 504 before and after the electronic zoom. , 505 do not move, in other words, the distance measurement frames 504 and 505 do not deviate from the main subject 503 of the captured image 69 output by the imaging unit 6, and the focused state with respect to the main subject 503 can be maintained.

  Furthermore, since the relative position of the center of gravity 303 of the main subject 503 with respect to the angle of view 501 and 502 is maintained, electronic zooming is performed after the Y user decides the composition of the main subject 503 while paying attention to the golden ratio and the like. Even if you do, the golden ratio is maintained and the composition remains intact.

[Moving rangefinder frame]
Next, an operation when the distance measuring frame is moved after the electronic zoom will be described.

  FIG. 10 is a diagram illustrating a state in which the distance measurement frame is moved on the display 1001 of the display unit 3, and illustrates a case where the user moves the distance measurement frame from the position indicated by reference numeral 1002 to the position indicated by reference numeral 1003. The same applies to the case where the distance measuring frame is automatically moved following the main subject. Two methods for determining the cut-out position of the field angle and the position of the distance measurement frame at this time will be described.

  FIG. 11 is a diagram showing a first method (referred to as method A-1) for determining the cut-out position of the angle of view and the position of the distance measurement frame, and reference numeral 1101 indicates the angle of view at the same magnification.

  When the distance measuring frame 1104 is positioned when the angle of view is in a state indicated by reference numeral 1102 by electronic zoom, the angle of view after the distance measuring frame is moved is moved to a position indicated by reference numeral 1103. This is a method of moving the angle of view so as to satisfy the above-described equation (1) as the distance measurement frame moves. Accordingly, this is a method in which the relative position of the distance measurement frame (the relative position of the center of gravity of the subject) is always cut out so as to be constant with respect to the field angle 1101 of the same magnification and the field angle 1102 or 1103 after zooming.

  FIG. 12 is a diagram showing a second method (referred to as method A-2) for determining the cut-out position of the angle of view and the position of the distance measurement frame.

  When the angle of view is in the state indicated by reference numeral 1102 by electronic zoom, the angle of view 1202 is not changed even if the distance measurement frame is positioned from reference numeral 1104 to reference numeral 1106. Method A-2 is a method in which the relative position of the distance measurement frame (the relative position of the center of gravity of the subject) changes with respect to the same angle of view 1101 and the angle of view 1102 after zooming after the distance measurement frame is moved. .

  Next, an operation when the distance measurement frame is moved after the electronic zoom and the electronic zoom magnification is changed will be described. In the case of method A-1 shown in FIG. 11, since the relative position of the distance measurement frame is always maintained with respect to the angle of view, the method described in FIG. 3 is applied as it is. On the other hand, the method A-2 shown in FIG. 12 has the following two operations.

  FIG. 13 is a diagram showing a first operation (referred to as method B-1) when the distance measuring frame is moved after the electronic zoom and the electronic zoom magnification is changed, and the angle of view 1102 is changed to the angle of view 1107 by the electronic zoom. The case where it is changed to is shown.

  With the electronic zoom, the distance measurement frame 1104 is changed to the distance measurement frame 1108. At this time, the angle of view 1107 after the electronic zoom is determined so as to maintain the relative position of the distance measurement frame with reference to the position of the distance measurement frame 1104 with respect to the angle of view 1102. Therefore, the center of the distance measurement frame does not move after the electronic zoom. However, the angle of view 1107 may fall outside the range of the captured image 6a output by the imaging unit 6. In this case, the angle of view is cut out so as to contact the end of the captured image 6a. There are two types of distance measurement frame positions in this case: (1) maintaining a relative position with respect to the angle of view 1107, and (2) maintaining a position on the captured image 6a.

  FIG. 14 is a diagram showing a second operation (referred to as method B-2) when the distance measuring frame is moved after the electronic zoom and the electronic zoom magnification is changed. The field angle 1102 is changed to the field angle 1109 by the electronic zoom. The case where it is changed to is shown.

  With the electronic zoom, the distance measurement frame 1104 is changed to the distance measurement frame 1110. At this time, the angle of view 1109 is determined so that the relative position of the distance measurement frame before and after the change matches the same-size angle of view 1101.

  The user can select the above-described method A-1 or method A-2 by using the menu screen displayed on the display unit 3 and the operation unit 4, and if the method A-2 is selected, the method B- 1 or method B-2 can be selected.

[Multiple ranging frames]
Next, a method for obtaining the center of gravity of the main subject and the electronic zoom method when there are a plurality of distance measuring frames will be described.

FIG. 15 is a diagram showing an example in which nine ranging frames are arranged in a 3 × 3 matrix, and a field angle before electronic zoom is denoted by reference numeral 1501. It is assumed that focusing is performed on three of the ranging frames 1502 to 1510 among the nine ranging frames 1502 to 1510. At this time, the center of gravity of the main subject is set to be the center of gravity 1514 of a triangle whose vertex is the center of gravity of each of the distance measurement frames 1505, 1508, and 1509. The coordinates (Xg, Yg) of the center of gravity 1514 are expressed by Expression (2).
Xg = (Xa + Xb + Xc) / 3
Yg = (Ya + Yb + Yc) / 3… (2)
Where (Xa, Ya) (Xb, Yb) (Xc, Yc) is the barycentric coordinates of each distance measurement frame

  Then, similarly to the method shown in FIG. 3, the angle of view after electronic zoom is determined, and the nine distance measuring frames after electronic zoom are arranged so that the relative positions of the center of gravity 1514 of the main subject with respect to the angle of view coincide. To do. The position of the distance measurement frame with respect to the angle of view after the electronic zoom is apparently equivalent to FIG.

The center-of-gravity coordinates of the main subject are expressed by Expression (2) when there are three focusing frames, but are expressed by Expression (3) when there are N focusing frames.
Xg = ΣXi / N
Yg = ΣYi / N (3)

  Next, a description will be given of a case where each distance measurement frame is not the same shape, and each distance measurement frame is weighted. FIG. 16 is a diagram showing the focusing state of the distance measurement frames having different shapes and weights and the center of gravity 1609 of the main subject in that case. Note that FIG. 16 shows only four ranging frames 1601, 1602, 1603, and 1604 that are in focus among a plurality of ranging frames.

In this case, the coordinates (Xg, Yg) of the center of gravity 1609 of the main subject are expressed by Expression (4).
Xg = (WaXa + WbXb + WcXc + WdXd) / (Wa + Wb + Wc)
Yg = (WaYa + WbYb + WcYc + WdYd) / (Wa + Wb + Wc)… (4)
Where (Xa, Ya) (Xb, Yb) (Xc, Yc) (Xd, Yd) are the barycentric coordinates of each distance measurement frame
Wa, Wb, Wc, Wd are the weights of each distance measurement frame

  Then, similarly to the method shown in FIG. 3, the angle of view after electronic zoom is determined, and a plurality of distance measuring frames after electronic zoom are arranged so that the relative positions of the center of gravity 1609 of the main subject with respect to the angle of view coincide. To do.

The coordinates of the center of gravity 1609 of the main subject are expressed by equation (4) when there are three focusing frames, but are expressed by equation (5) when there are N focusing frames.
Xg = ΣWiXi / ΣWi
Yg = ΣWiYi / ΣWi (5)
