Description

  The present invention relates to an imaging apparatus, an imaging method, and a program that can shoot a subject.

  Recently, a digital still camera (hereinafter referred to as a “digital camera”) capable of recording captured image data obtained in a semiconductor memory has become more widely used than a conventional camera that records an image on a silver salt film. It is popular.

By the way, in photographing a subject, photographing is often performed so that a subject image is horizontal. In such a case, the digital camera is held horizontally and shooting is performed, but a slight tilt may occur due to camera shake or the like. For this reason, conventionally, there has been proposed a technique for performing predetermined processing on photographed image data photographed so that the subject image is horizontal. For example, a sensor for detecting the tilt of the digital camera itself is provided, and the detection result by this sensor is displayed. The captured image (data) is rotated according to a technique (for example, see Patent Document 1) that enables confirmation of the horizontality of the image by displaying it on the display means or a set of predetermined image composition (image composition) rules. A technique for correcting the inclination or rotation of an image (data) by trimming (cropping) an object is disclosed (for example, see Patent Document 2).

Arrange.

  The power key 105 is operated every time the power is turned on / off, and the shutter key 106 instructs photographing in the photographing mode. The SET button 110 functions as an execution key for instructing setting / execution in menu selection or the like.

  On the back of the digital camera 100, a mode switching button 107, a menu button 108, a cross key 109, a SET button 110, a DISP button 111, an optical viewfinder 112, a strobe charge lamp 113, a zoom switching key 114, and a display unit 32 are arranged. To do.

  A mode switching button 107 switches between a photographing mode “R” and a reproduction mode “P” which are basic modes. The menu button 108 is operated when displaying various menu items and the like. The cross key 109 is formed integrally with keys for moving the cursor in the up, down, left, and right directions.

  The SET button 110 is used when the cursor frame is displayed on the menu screen or the like, and the menu displayed on the menu screen is selected by operating the movement of the cursor frame with the cross key 109. The DISP button 111 is a button for displaying various information on the monitor screen, and displays or displays the number of pixels, image quality, distinction between still images and moving images, date, time, remaining battery power, remaining memory capacity, and the like. Is switched so that only the image is displayed.

  In the present embodiment, by performing a predetermined operation through the various operation buttons described above, a predetermined angle is obtained based on one captured image data acquired in response to a single shooting instruction (pressing the shutter key 106). It is assumed that a multi-angle shooting mode for generating a plurality of corrected image data rotated every time can be selected.

  The display unit 32 is composed of a color liquid crystal panel with a backlight, and displays a through image on the monitor as an electronic viewfinder in the recording mode, while reproducing and displaying the selected image in the reproduction mode.

  Although not shown, the digital camera 100 has a bottom surface of the digital camera 100 such as a USB (Universal Serial) as a memory card slot for attaching / detaching a memory card used as a recording medium or a serial interface connector for connecting to an external personal computer or the like. Bus) connector and the like are provided.

Next, the internal configuration of the digital camera 100 will be described with reference to FIG.
The digital camera 100 can be roughly divided into an imaging system 10, an operation system 20, a display system 30, an image data storage system 40, a control system 50, and the like according to functions.

  The imaging system 10 includes a photographing lens group 11 having a zoom function and an autofocus function housed in a lens barrel 101, and a CCD that converts a subject image that has passed through the photographing lens group 11 into a two-dimensional image signal (data). (Charge Coupled Devices), an imaging unit 12 made of an imaging element such as CMOS (Complementary Metal Oxide Semiconductor), and a Bayer data memory 131 that temporarily holds image data output from the imaging unit 12 in the form of Bayer data, An image processing unit 13 that performs predetermined image processing on the image data stored in the Bayer data memory 131, an image memory 14 that temporarily stores image data after image processing, a focus mechanism of the lens barrel 101, and a zoom mechanism Drive means (not shown) for driving, strobe drive means (not shown) for driving the strobe light emitting unit 104, and the like are provided. . Note that, in the imaging unit 12 described above, a primary color Bayer array color (RGB) filter is disposed in front of the imaging element that the imaging unit 12 shakes.

  Here, the image processing unit 13 performs predetermined signal processing on the Bayer data temporarily stored in the Bayer data memory 131, thereby obtaining luminance and color difference multiplexed signals (Y, Cb, Cr data, or Y, U, and V) are generated, and image data of the Y data, U data, and V data (hereinafter referred to as “captured image data”) is stored in the image memory 14, respectively.

  The captured image data stored in the image memory 14 includes, for example, luminance (Y) data composed of 1600 × 1200 pixels and color difference (U, V) data composed of 800 × 600 pixels. This is because the amount of information of the color difference signal is reduced because the luminance signal is more easily perceived by the human eye, but the present invention is not limited to this, and the same number may be used. The captured image data temporarily stored in the image memory 14 is output to the control system 50.

  The operation system 20 includes various operation buttons provided on each part of the body, that is, a power key 105, a shutter key 106, a mode switching button 107, a menu button 108, a cross key 109, a SET button 110, a DISP button 111, a zoom. An operation input unit 21 including a switching key 114 and an input circuit 22 for inputting an operation signal from the operation input unit 21 to the control circuit 51 of the control system 50 are provided.

  The display system 30 displays a display control unit 31 including a video memory (VRAM) 311 that temporarily holds display data output from the control circuit 51 of the control system 50, and an output signal from the display control unit 31. And a display unit 32 such as an LCD (Liquid Crystal Display) and a CRT (Cathode Ray Tube).

  The image data storage system 40 includes an I / F unit 41 such as the above-described memory card slot and serial interface connector, a memory card for storing image data connected to the I / F unit 41, an HDD (Hard Disk Drive), and the like. And a storage unit 42 that can rewrite the data.

  The control system 50 includes a control circuit 51 including a CPU (Central Processing Unit) that controls each of the above systems to control the operation of the digital camera 100, and various programs and data necessary for the operation of the CPU. A program memory 52 such as a ROM (Read Only Memory) that is stored in a nonvolatile manner, and a data memory 53 such as a RAM (Random Access Memory) that temporarily stores data such as processing results generated when various programs are executed.

  When the control circuit 51 refers to the angle table 521 stored in advance in the program memory 52 and reads out the tilt angle corresponding to the number of generated images and the tilt index value input from the operation input unit 21, the captured image is captured at this tilt angle. A rotation process for rotating the data and generating corrected image data based on the rotated image data is executed.

Hereinafter, the rotation process will be described with reference to FIGS. 4 and 5.
FIG. 4A is a diagram schematically showing captured image data G input from the imaging system 10. Here, assuming that an inclination angle (for example, α degrees) is read from the angle table 521 based on the number of generated images and the inclination index value input from the operation input unit 21, the control circuit 51 has a predetermined reference point. The image data obtained by rotating the photographed image data G by α degrees around the center is generated (see FIG. 4B). In FIG. 4B, the reference point that is the center of rotation is the lower left O point of the captured image data G. However, the present invention is not limited to this, and the center of the captured image data G may be the reference point. The position may be used as a reference point.

  Next, the center of a rectangular area (x ′, y ′) that is similar in shape to the image area (x, y) of the captured image data G input from the imaging system 10 and has the same orientation as each other is rotated. It is arranged at the center of the image area of the image data G, and is arranged so that two opposite vertices of the rectangular area are inscribed in the image area of the photographed image data G, and is surrounded by the rectangular area (x ′, y ′). Image data G ′ is extracted (see FIG. 5A). That is, in the rotated photographed image data G, a rectangular area having the largest area is arranged, and image data G ′ for this rectangular area is extracted. Here, since the shape of the rectangular area is similar to the image size of the captured image data input from the imaging system 10 and has the same orientation, corrected image data that does not feel strange when changing the image size described later is generated. can do. The shape and orientation of the rectangular area are not limited to this.

Then, the extracted image data G ′ is enlarged to an image size equivalent to the image area (x, y) of the photographed image data G input from the imaging system 10, and the enlarged image data G ′ is corrected image data. (See FIG. 5B). Thereby, the corrected image data can be generated in the same form as the captured image data. Thus, since the corrected image data is directly generated from the YUV data that is the captured image data, a high-quality image can be obtained. In the present embodiment, the rectangular area is enlarged to the same image size as the image area (x, y) of the captured image data G. However, the present invention is not limited to this, and the rectangular area is enlarged or reduced to an arbitrary size. Also good.
Further, this series of processing may be configured automatically, thereby eliminating trouble for the user.
By taking the above configuration, the center of the captured image data always coincides with the center of the rectangular area. Therefore, there is a merit that it is easy to compare the state of rotation when the generated corrected image data are arranged. .

  The control circuit 51 performs predetermined image processing on the captured image data and the corrected image data to generate image data that conforms to the JPEG (Joint Photographic Experts Group) format, and uses this image data as storage image data. The data is stored in the storage unit 42. Further, the control circuit 51 performs predetermined image processing on the captured image data and the corrected image data, thereby reducing thumbnail image data for thumbnail display conforming to a format such as GIF (Graphic Interchange Format) or PNG (Portable Network Graphics). The reduced image data is stored in the storage unit 42 as display image data and displayed on the display unit 32.

Next, the operation of the digital camera 100 in this embodiment will be described.
FIG. 6 is a flowchart showing a procedure of multi-angle shooting processing performed at the time of subject shooting. Each process in FIG. 6 represents a process executed under the control of the control circuit 51 and in cooperation with a predetermined program and data stored in the program memory 52. Further, as a premise of this processing, it is assumed that the shooting mode is selected by the mode switching button 107 and the multi-angle shooting mode is selected.

  First, when an operation signal instructing the multi-angle shooting mode is input via the operation input unit 21 (Step S11; Yes), a screen for allowing the user to set the number of images to be generated is displayed on the display unit 32 (Step S11). In step S12, input of the number of generated images is waited (step S13; No).

  FIG. 7A is a diagram illustrating an example of the display screen displayed on the display unit 32 in step S12. As shown in the figure, based on the display screen, any one of “5”, “9”, “13”, and “25” is set to the cross key 109 of the operation input unit 21 and the SET. It can be selectively specified via the button 110. Note that the number of generated images that can be specified is not limited to the example illustrated in FIG.

  Returning to FIG. 6, if it is determined in step S13 that the number of generated images has been input (step S13; Yes), the number of generated images is stored in the data memory 53 (step S14). Next, a screen for setting the inclination angle for each image of the number of generated images specified previously is displayed on the display unit 32 (step S15), and input of this inclination angle (inclination index value) is waited (step S16; No).

  FIG. 7B is a diagram illustrating an example of the display screen displayed in step S15. As shown in the figure, an inclination angle for each image is displayed as an index value of 1 to 5 (hereinafter referred to as an inclination index value), and any one of values 1 to 5 is input based on this display screen. It can be selectively specified via the cross key 109 and the SET button 110 of the unit 21. Here, the values of 1 to 5 indicate the degree of the tilt angle, and the tilt angle for each image increases in ascending order of the value. In this embodiment, the inclination angle for each image is displayed and selected as an inclination index value indicating the degree of the inclination angle. However, the present invention is not limited to this, and the value of the inclination angle for each desired image is set. It is good also as an aspect which can input directly.

  Returning to FIG. 6, if it is determined in step S16 that the tilt angle (tilt index value) for each image has been input (step S16; Yes), this index value is stored in the data memory 53 (step S17). Next, it is determined whether or not the shutter key 106 of the operation input unit 21 is pressed, and when an operation signal is input by pressing the shutter key 106 (step S18; Yes), the imaging system 10 is controlled to control the subject. Is taken (step S19). By this shooting, Bayer data from the imaging unit 12 is held in the image processing unit 13, and the Y, U, and V data generated by the above-described image processing, that is, the captured image data is temporarily stored in the image memory 14, and control is performed. It is output to the circuit 51.

  Subsequently, the captured image data input from the image memory 14 is stored in the data memory 53 (step S20), and the process proceeds to the multi-angle image generation process in step S21.

Hereinafter, the multi-angle image generation processing in step S21 will be described with reference to FIG.
First, the angle table 521 stored in advance in the program memory 52 is referred to, and the inclination angle corresponding to the number of generated images and the inclination index value stored in the data memory 53 by the previous processing is read (step S211).

FIG. 9 is a diagram illustrating a data configuration example of the angle table 521 stored in the program memory 52.
The angle table 521 defines an inclination angle (unit: degrees) for each image corresponding to the number of generated images and the inclination index value. For example, when “9” is selected as the number of generated images and “4” is selected as the tilt index value, the row corresponding to the image number “−4 ≦ n ≦ 4” corresponds to the row of the tilt index value “4”. The record R1 to be read is referred to and its value is read. Here, the relationship between the number N of generated images and the image number n is − (N−1) / 2 ≦ n ≦ (N−1) / 2.

  In this process, the inclination angle corresponding to the smallest value of the image number n is first read. For example, in the case of the above condition, the inclination angle “−8” degree of the image number “−4” is the first. Will be read. It is assumed that the current image number n and the maximum image number nmax related to the number of generated images are temporarily stored in the data memory 53.

  Returning to FIG. 8, based on the photographed image data stored in the data memory 53, a rotation process is performed based on the tilt angle (eg, −8 degrees) read in step S211 to generate corrected image data (step S212). Then, the corrected image data is converted into the JPEG format (step S213), and the image data in the JPEG format is stored in the storage unit 42 as storage image data (step S214). Here, when the image number n = 0, the rotation processing is not performed, and the image data for saving is generated by converting the captured image data into the JPEG format.

  Next, it is determined whether or not the current value of the image number n has reached the value of nmax. If it is determined that the value has not reached (No in step S215), the value of the image number n is incremented by 1. (Step S216), the process returns to Step S211 again, and Steps S211 to S216 are repeated until the image number nmax is reached.

  On the other hand, when it is determined in step S215 that the current value of the image number n has reached the value of nmax (step S215; Yes), this processing ends and the multi-angle shooting processing in FIG. 6 ends. To do.

  As described above, according to the first embodiment, a plurality of corrected image data obtained by rotating the photographed image data by a predetermined angle is generated based on one photographed image data acquired by one photographing. Therefore, even when a slight tilt occurs due to camera shake or the like, the horizontality of the image can be easily obtained. Further, since an inclination detection sensor or the like is not required, cost can be suppressed.

<Second Embodiment>
Hereinafter, a second embodiment when the present invention is applied to a digital camera will be described with reference to the drawings. The external configuration is basically the same as that shown in FIG. 1 and FIG. 2 and the internal configuration is the same as that shown in FIG. Reference numerals are used, and illustration and description thereof are omitted.

The operation of the digital camera 100 in this embodiment will be described.
FIG. 10 is a flowchart showing the procedure of the multi-angle shooting process performed when shooting the subject. Each process in FIG. 10 shows a process executed under the control of the control circuit 51 and in cooperation with a predetermined program and data stored in the program memory 52. Further, as a premise of this processing, it is assumed that the shooting mode is selected by the mode switching button 107 and the multi-angle shooting mode is selected.

  In FIG. 10, the operations in steps S31 to S40 are the same as those in steps S11 to S20 (see FIG. 6) of the digital camera 100 according to the first embodiment, and thus description thereof is omitted.

Hereinafter, the multi-angle image generation processing in step S41 will be described with reference to FIG.
First, the angle table 521 stored in advance in the program memory 52 is referred to, and the inclination angle corresponding to the number of generated images and the inclination index value stored in the data memory 53 by the previous processing is read (step S411).

  Next, based on the photographed image data stored in the data memory 53, rotation processing is performed based on the tilt angle read in step S411, and corrected image data is generated (step S412). Then, reduced image data is generated from the corrected image data (step S413) and stored as display image data in the storage unit 42 in association with the image number n (step S414). Here, when the image number n = 0, the rotation processing is not performed, and reduced image data such as a thumbnail image is generated from the captured image data.

  Subsequently, it is determined whether or not the current value of the image number n has reached the value of nmax. If it is determined that the current value has not reached (No in step S415), the value of the image number n is incremented by one. Then (step S416), the process returns to step S411 again, and steps S411 to S416 are repeated until the image number nmax is reached.

  On the other hand, when it is determined in step S415 that the current value of the image number n has reached the value of nmax (step S415; Yes), this process ends, and the process proceeds to step S42 in FIG.

  Returning to FIG. 10, in step S42, the display image data stored in the storage unit 42 is displayed on the display unit 32 in ascending order of the image numbers n stored in association with the display image data (step S42). ), And waits until specific display image data is selected (step S43).

  FIG. 12A is a diagram illustrating an example of the display screen displayed in step S42. As shown in the figure, display image data is displayed in a list from the upper left end of the screen to the lower right end of the screen in ascending order of the image number n. Based on this display screen, specific display image data is sent to the operation input unit 21. The cross key 109 and the SET button 110 can be selectively designated. This figure illustrates the case where the image number is −4 ≦ n ≦ 4, that is, the number of generated images is 9. Since the corrected image data corresponding to the angular displacement from the image data is sequentially displayed before and after the image data, it is possible to easily compare the images and easily check the horizontality of the images. Can do.

  Here, the display image data in the center of the display screen is the image number n = 0, that is, the display image data of the captured image data acquired by capturing, and before and after the display image data of the captured image data, Display image data for corrected image data corresponding to the angular displacement from the captured image data is sequentially displayed. Thereby, each image can be easily compared, and the horizontality of the image can be easily confirmed.

  The display image data of the captured image data is highlighted so that it can be distinguished from other display image data. As described above, since the captured image data is highlighted, it is possible to easily identify the captured image data acquired by capturing. The mode of highlighting is not particularly limited, and the initial display position of the selection cursor icon for selecting specific display image data may be arranged on the display image data with the image number n = 0. (See FIG. 12A.) Only the display image data with the image number n = 0 may be blinked.

  If it is impossible to display a list of all display image data in the display screen of the display unit 32, as shown in FIG. 12B, the display image data is displayed over a plurality of display screens. May be displayed. The figure illustrates the case where the image number is −13 ≦ n ≦ 13, that is, the number of generated images is 27.

  In such a case, for example, when the left key of the cross key 109 is pressed when the selection cursor is on the display image data of the image number “−1” on the display screen D2, the screen is displayed on the display screen D1. Switching may be performed so that the selection cursor is placed on the display image data with the image number “−8”. However, the left key is pressed when the selection cursor is at the image number “−7” of the display screen D1, or the right key is pressed when the selection cursor is at the image number “7” of the ideographic screen D3. In this case, it is assumed that the screen is not switched. In FIG. 12, display image data is arranged in a 3 × 3 display frame, and a display example is shown. However, the present invention is not limited to this, and the mode such as 1 × 3 or 5 × 5 can be arbitrarily set. Suppose that

  Returning to FIG. 10, when it is determined in step S43 that specific display image data has been selected (step S43; Yes), the image number associated with the selected display image data is read (step S43). In step S44, the inclination angle corresponding to the image number is read from the angle table 521 (step S45).

  Next, based on the photographed image data stored in the data memory 53, corrected image data that has been rotated at the tilt angle read in step S45 is generated (step S46). Then, the corrected image data is converted into the JPEG format (step S47), and the image data in the JPEG format is stored in the storage unit 42 as storage image data (step S48). Further, all the display image data stored in the storage unit 42 is deleted (step S49), and this process ends.

As described above, according to the second embodiment, a plurality of corrected image data obtained by rotating the photographed image data by a predetermined angle is generated based on one photographed image data acquired by one photographing. Therefore, even when a slight tilt occurs due to camera shake or the like, the horizontality of the image can be easily obtained. Further, since an inclination detection sensor or the like is not required, cost can be suppressed. In addition, since the photographed image data and the corrected image data can be displayed in a list, it is possible to easily check the horizontality of the image. Further, since only the designated photographed image data or specific corrected image data is stored, the storage capacity can be saved.
Further, since the operator can directly check and select an image that seems to be optimal, an inappropriate image is not selected by automatic identification.
Further, since the photographed image data and the corrected image data can be displayed in a list, the images can be selected while being compared with each other, so that the selectivity is improved.
Further, by highlighting the photographed image data, it becomes easier to understand by comparing with other images how much the photographed image was tilted. In addition, since an icon for selecting image data is displayed, the user can operate while confirming the image to be currently selected, and the initial display position of the icon is above the captured image data. Therefore, the initial position is the center of the image displayed as a list, and it is easy to select an image.

  In step S49, all the display image data stored in the storage unit 42 is erased. However, other than the display image data related to the storage image data may be deleted. It is preferable to store the image data and the display image data in association with each other.

  The detailed configuration and detailed operation of the image forming apparatus in the above embodiment can be changed as appropriate without departing from the spirit of the present invention.
