It is the figure which showed typically the specific example of the image acquisition timing in pre-capture photography. It is a 1st figure which shows the specific example of a synthesized image. It is a 2nd figure which shows the specific example of a synthesized image. It is a 3rd figure which shows the specific example of a synthesized image.

  FIG. 1 is a block diagram illustrating a configuration of an embodiment of a camera according to the present embodiment. The camera 100 includes an operation member 101, a lens 102, an image sensor 103, a control device 104, a memory card slot 105, and a monitor 106. The operation member 101 includes various input members operated by the user, such as a power button, a release button, a zoom button, a cross key, an enter button, a play button, and a delete button.

  The lens 102 may be configured to be detachable from the camera 100 via a mount unit (not shown), or may be integrated with the camera 100. The lens 102 is composed of a plurality of optical lenses, but in FIG. 1, it is represented by a single lens. The image sensor 103 is configured by an image sensor such as a CMOS, for example, and generates an analog image signal by photoelectrically converting a subject image formed by a light beam that has passed through the lens 102, and outputs the generated analog image signal to the control device 104.

  The control device 104 includes a CPU, a memory, and other peripheral circuits, and controls the camera 100. Note that the memory constituting the control device 104 includes SDRAM and flash memory. The SDRAM is a volatile memory, and is used as a work memory for the CPU to develop a program when the program is executed or as a buffer memory for temporarily recording data. The flash memory is a non-volatile memory in which data of a program executed by the control device 104, various parameters read during program execution, and the like are recorded.

  The control device 104 converts the analog image signal input from the image sensor 103 into a digital image signal, and after performing various image processing, generates main image data in a predetermined image format, for example, JPEG format. Further, the control device 104 generates display image data, for example, thumbnail image data, based on the generated main image data. The control device 104 generates an image file that includes the main image data and the thumbnail image data, and further includes header information, and outputs the image file to the memory card slot 105.

  The memory card slot 105 is a slot for inserting a memory card as a storage medium, and the image file output from the control device 104 is written and recorded on the memory card. The memory card slot 105 reads an image file stored in the memory card based on an instruction from the control device 104.

  The monitor 106 is a liquid crystal monitor (rear monitor) mounted on the back surface of the camera 100, and the monitor 106 displays an image stored in a memory card, a setting menu for setting the camera 100, and the like. . Further, when the mode of the camera 100 is set to the live view mode by the user, the control device 104 outputs image data for display of images acquired from the image sensor 103 in time series to the monitor 106. As a result, a through image is displayed on the monitor 106.

  The camera 100 in the present embodiment performs pre-capture shooting by performing continuous shooting at a high speed (for example, a speed of 30 fps, 60 fps, etc.) when a preliminary operation for shooting is performed by the user. When an operation for instructing photographing is performed by the user, a plurality of images acquired by the pre-capture photographing are evaluated using a predetermined evaluation value. A best shot shooting function is provided for selecting a best shot image and recording the selected best shot image on a memory card.

  For example, the control device 104 detects a half-press operation of the release button included in the operation member 101 by the user as the preliminary operation, starts a shooting preparation process such as an autofocus process, and performs the above-described pre-capture shooting. . Thereafter, when the release button is fully pressed by the user, the control device 104 determines that an operation for instructing the photographing has been performed, and selects the best shot image.

  The best shot image selection method is a well-known process and will not be described in detail. However, each pre-capture image is analyzed and an image generally evaluated as good is automatically selected. Thus, the evaluation value is calculated. For example, an evaluation value of an image with a large amount of camera shake or an image in which a person closes his / her eyes is calculated with a low evaluation value and is difficult to be selected as a best shot image. The control device 104 selects, as a best shot image, an image having the highest evaluation value calculated for selecting the best shot image from among a plurality of images acquired by pre-capture shooting.

  In the present embodiment, the control device 104 selects two or more images including at least a best shot image based on a predetermined selection condition from a plurality of images acquired by the above-described pre-capture shooting function. By selecting and synthesizing these images, a synthesized image in which a rendering effect is added to the best shot image is generated. Note that selection conditions for images used for composition will be described later. The control device 104 records the best shot image acquired by a series of preliminary operations by the user and operations for shooting instructions and the composite image in association with each other on the memory card. As a result, the camera 100 according to the present embodiment can automatically select the best shot image, generate a composite image in which a production effect is given to the best shot image, and record them in association with each other.

  FIG. 2 is a flowchart showing a flow of photographing processing in the present embodiment. The process shown in FIG. 2 is executed by the control device 104 as a program that is activated when the user sets the mode of the camera 100 to the mode for recording the best shot image and the synthesized image in association with each other.

  In step S <b> 1, the control device 104 determines whether or not the above-described preliminary operation for photographing has been performed by the user pressing the release button included in the operation member 101 halfway. If a positive determination is made in step S1, the process proceeds to step S2.

  In step S2, the control device 104 sets times A, B, and C for controlling the image acquisition timing in the pre-capture shooting as shown in FIG. An example of setting the times A, B, and C is shown in FIG. In FIG. 3, the horizontal axis represents time, the release button is half-pressed at time t0, and the release button is fully pressed at time t1. In the present embodiment, the control device 104 detects a half-press of the release button at time t0, and then performs high-speed continuous shooting by pre-capture shooting during time C to obtain a plurality of images.

  For example, the time C is set according to the continuous shooting speed and the number of images to be acquired by continuous shooting. Here, the time C is necessary to acquire 20 images by performing high-speed continuous shooting at a speed of 60 fps. Time is set. Time A is set according to how many images are acquired before the release button is fully pressed at time t1, and time B is how many images are acquired after the release button is fully pressed at time t1. It is set according to whether to acquire. For example, out of 20 images, when acquiring 12 images before the release button is fully pressed and 8 images after the release button is fully pressed, time C = time A + time B and time A: time Times A and B are set so that B is 6: 4. Then, it progresses to step S3.

  In step S3, the control device 104 performs a release standby process. In the present embodiment, as described above, detection of an input signal from the release button is continued while performing high-speed continuous shooting and pre-capture shooting, and the user waits for a full pressing operation of the release button. In the present embodiment, as shown in FIG. 3, before the release button is fully pressed, continuous shooting may be performed only during time A. However, the timing (time of the release button being fully pressed) Since t1) depends on the operation timing of the user, the control device 104 cannot predict this timing. Therefore, the control device 104 starts pre-capture shooting after the release button is half-pressed by the user and acquires an image. In a later process, the control device 104 selects time A from the acquired image. Only images taken during the period are extracted.

  Thereafter, the process proceeds to step S4, and the control device 104 determines whether or not the user has detected a full-press operation of the release button within a predetermined time after detecting the half-press of the release button. If a negative determination is made in step S4, the process returns to step S1. As a result, when the full-press operation is not performed within a predetermined time from the half-press operation of the release button, the process can be timed out. On the other hand, if an affirmative determination is made in step S4, the process proceeds to step S5.

  In step S5, the control device 104 starts a release process. Specifically, as shown in FIG. 3, the control device 104 continues continuous shooting for a time B after the release button is fully pressed at time t1. Thereafter, the process proceeds to step S6, where the control device 104 ends the continuous shooting after the time B has elapsed from the time t1 and ends the image acquisition by the pre-capture shooting as shown in FIG. At this time, as described above, the control device 104 extracts an image acquired during time A before time t1 from images acquired by pre-capture photography before time t1. Then, the image acquired during time A before time t1 and the image acquired after time t1 are stored in the buffer memory as images acquired by pre-capture photography (hereinafter referred to as “pre-capture images”). Record. Thereby, the pre-capture image (preliminary image) acquired during the time C shown in FIG. 3 can be recorded in the buffer memory. Thereafter, the process proceeds to step S7.

  In step S7, the control device 104 performs a known best shot image selection process on the pre-capture image recorded in the buffer memory in step S6, and selects the image having the highest calculated evaluation value as the best shot image. To do. Thereby, for example, one best shot image is selected from the 20 pre-capture images taken during the time C.

  Thereafter, the process proceeds to step S8, and the control device 104 selects a plurality of compositing images from the pre-capture images. In this embodiment, it is assumed that the number of images to be combined is set in advance. The set number of sheets may be arbitrarily changed by the user. Alternatively, the control device 104 may set the number of images based on the shooting conditions and the subject. For example, when the movement of the subject is fast or the movement amount is large, the control device 104 increases the set number so that the composite image accurately represents the movement of the subject. In addition, when the setting is made so as to synthesize four images, the control device 104 selects from the pre-capture images in order to synthesize four images including the best shot image selected in step S7. Three images selected excluding the best shot image are selected as images for synthesis.

  Here, an example of selection conditions for the composition image in the present embodiment will be shown. In the present embodiment, it is assumed that the control device 104 selects a composition image based on, for example, shooting conditions and a subject. Specifically, the control device 104 controls the camera movement direction, the camera movement amount, and the main subject type in each pre-capture image when the user changes the shooting direction by shaking the camera when shooting the pre-capture image. The composition image is selected in accordance with one or a combination of the type of shooting scene, the amount of movement of the main subject, the pose and arrangement of the main subject, and the like. Note that the direction and amount of movement of the camera can be detected by providing the camera 100 with a gyro sensor or the like, and can be determined by detecting these at the time of shooting and associating them with the image. The type of main subject and the type of shooting scene can be determined by associating the scene determination result at the time of shooting with an image. The movement amount of the main subject and the pose and arrangement of the main subject can be determined by performing subject recognition at the time of shooting and associating the recognition result with the image.

An example of the composition image generated in FIGS. 4 to 6 is shown. 4 is a composite image of a person shooting during a basketball game, FIG. 5 is a composite image of a jumping ballerina, and FIG. 6 is a composite image of a fluttering flag F.
For example, it is assumed that an image acquired by pre-capture shooting is an image of a person who makes a golf swing to shoot during a basketball game. In this case, the number of images for composition (three in the example of FIG. 4) corresponding to the amount of movement of the subject (the amount of movement of the person golf club) is selected. As a result, as shown in FIG. 4, it is possible to create an image for synthesis that represents the movement trajectory of the person shooting toward the basket goal as a production effect.

  Alternatively, it is assumed that an image acquired by pre-capture shooting is an image of a ballerina that jumps. In this case, the number of compositing images (three in the example of FIG. 5) corresponding to the camera swing direction, swing amount, and subject movement amount is selected. As a result, as shown in FIG. 5, it is possible to create an image for synthesis that represents the trajectory of the ballerina jump as a production effect. Alternatively, if the image acquired by the pre-capture shooting is an image obtained by swinging the camera with a stationary object, select the number of compositing images according to the camera swing direction and the swing amount. Thus, it is possible to create a composition image with a fantastic effect.

  Alternatively, it is assumed that the image acquired by the pre-capture shooting is an image obtained by shooting a waving flag. In this case, a plurality of compositing images are selected so that the amount of change in the shape of the flag F is a constant interval. As a result, as shown in FIG. 6, it is possible to create a composition image that represents the flickering of the flags F1 to F3 as a production effect.

  Thereafter, the process proceeds to step S9, and the control device 104 performs development processing on the best shot image selected in step S7 and the composition image selected in step S8. For example, when the best shot image selected in step S7 and the composition image selected in step S8 are RAW data, the control device 104 performs known development processing to generate image data. Thereafter, the process proceeds to step S10, and the control device 104 records the best shot image after the development processing in step S9 (hereinafter referred to as “development best shot image”) on the memory card. Then, it progresses to step S11.

  In step S <b> 11, the control device 104 performs gain correction on the composite image (hereinafter referred to as “post-development composite image”) after the development processing in step S <b> 9. At this time, the control device 104 performs gain correction by determining a gain correction amount to be applied to each post-development composition image in accordance with the number of post-development composition images. For example, when the number of post-development composition images is four, the gain correction amount applied to each post-development composition image is set to 0.25, and the total gain amount is set to one. Alternatively, in order to enhance the effect of the composite image, a higher gain is applied to the composite image close to the best shot image shooting timing (shooting time), and gain correction is performed slightly brighter, The gain to be applied may be lowered as the shooting time is farther from the best shot image. Thereafter, the process proceeds to step S12.

  In step S12, the control device 104 determines whether or not the swing amount of the camera 100 when the pre-capture image is captured is equal to or less than a predetermined swing amount (whether or not the swing amount is small). For example, the control device 104 detects a touch at the time of pre-capture shooting, and makes an affirmative determination in step S12 when the amount of touch is equal to or less than a predetermined value. If a positive determination is made in step S12, the process proceeds to step S13.

  In step S <b> 13, the control device 104 performs alignment between frames in a partial region in the image for the post-development best shot image and a plurality of post-development composition images. For example, the control device 104 determines the alignment amount by superimposing the feature points of a partial area of each image, and performs alignment processing (coordinate shift) for each image. As a feature point used for alignment, for example, an arbitrary point extracted from a background whose position does not change in the image may be used. Specifically, in the case of creating a compositing image representing the flickering of the flag F as shown in FIG. 6, an arbitrary point on the column supporting the flag F (for example, the column P in FIG. 6) is used. It is possible. Further, when the subject is a person, an arbitrary point on the face of the subject detected by the face recognition process may be used.

  When the plurality of images are aligned by performing the coordinate shift in this way, the data for all the images to be synthesized are not prepared in the peripheral pixels of the image. Crop each image so that Then, it progresses to step S14. On the other hand, if a negative determination is made in step S12, the process proceeds directly to step S14.

  In step S <b> 14, the control device 104 combines the post-development best shot image with the post-development composite image after gain correction. At this time, if the image alignment and cropping are performed in step S13, the control device 104 combines the cropped images. As a result, a composite image with a production effect can be created.

  Thereafter, the process proceeds to step S15, and the control device 104 records the composite image created in step S14 on the memory card in association with the post-development best shot image recorded in step S10, and ends the process. As a result, the best shot image selected from the plurality of pre-capture images can be recorded on the memory card in association with the best shot image and the combined image with the rendering effect.

According to the present embodiment described above, the following operational effects can be obtained.
(1) The control device 104 selects a best shot image from the pre-capture images acquired by the pre-capture shooting, extracts a plurality of compositing images from the pre-capture images, and extracts the plurality of compositing images and the best shot. The image is synthesized. The best shot image and the composite image are recorded in association with each other. Thereby, it is possible to record the best shot image and the synthesized image obtained by adding the effect to the best shot image in association with each other.

(2) The control device 104 selects an image having the highest evaluation value in the best shot image selection process from the pre-capture images as the best shot image. This makes it possible to select an image that is generally evaluated as the best from among pre-captured images as the best shot image.

(3) The control device 104 extracts a plurality of compositing images from the pre-capture image based on the shooting conditions and the subject. As a result, it is possible to extract an optimal compositing image according to the shooting conditions and the subject.

(4) The control device 104 determines the number of synthesis images to be extracted from the pre-capture image based on the shooting conditions and the subject. Thereby, it is possible to extract an optimal number of compositing images according to shooting conditions and subjects.

(5) The control device 104 performs gain correction on the post-development composition image, and synthesizes the composition image after the gain correction. As a result, it is possible to generate a composite image with a presentation effect.

(6) The control device 104 determines the gain amount to be applied to each compositing image based on the number of compositing images. As a result, it is possible to determine an optimum gain amount according to the number of images for synthesis.

(7) The control device 104 applies a higher gain to the synthesis image close to the shooting timing (shooting time) of the best shot image and performs gain correction slightly brighter than the other images, so that the best shot image is corrected. The gain is reduced as the shooting time is longer. As a result, the effect of rendering the composite image can be further enhanced.

(8) When the amount of camera shake at the time of pre-capture photographing is equal to or less than a predetermined value, the control device 104 performs alignment using a partial area in the image of the best shot image and the image for synthesis. As a result, when the amount of camera shake is very small, it is possible to create a composite image that has been aligned.

(9) The controller 104 crops each image after alignment. As a result, even when the data for all the images to be synthesized at the peripheral pixels of the image cannot be obtained due to the alignment, all the images for synthesis can be synthesized with the same size.

-Modification-
The camera according to the above-described embodiment can be modified as follows.
(1) In the above-described embodiment, the control device 104 has described an example in which an image having the highest evaluation value calculated by a known best shot image selection process is selected as the best shot image. However, the user may be able to change the best shot image automatically selected by the control device 104 to another image. For example, the control device 104 may display the automatically selected best shot image and other pre-capture images on the monitor 106 and present them to the user, and accept a change from the best shot image from the user. . The control device 104 selects the best shot image by the user when an image different from the image automatically selected by the control device 104 is selected as the best shot image from the pre-capture images by the user. Select the image again. Thus, the user can change the best shot image to a favorite image.

(2) In the above-described embodiment, the example in which the control device 104 performs synthesis after performing gain correction on the synthesis image after the development processing has been described. However, the control device 104 may perform synthesis after performing gain correction on the RAW data before the development processing, and develop the RAW data after the synthesis. Whether to perform gain correction after development processing or to perform gain correction before development processing determines at least one of the type of main subject, the type of shooting scene, the ISO sensitivity, the image quality mode, and the computation time required for development processing. Switching may be performed based on one.

(3) When developing the composition image, the control device 104, the camera swing direction, the camera swing amount, the main subject type, the shooting scene type, the main subject movement amount, the main subject pose and arrangement Based on the above, the development parameters applied to each composition image may be changed. However, it is preferable that a default development parameter is applied to the composition image near the best shot image capturing timing so that the best shot image becomes a base tone.

(4) In the above-described embodiment, the control device 104 has described an example in which one composition image is created for one best shot image, and the images are associated and recorded. However, the control device 104 may create a plurality of images for composition with different effects for one best shot image. In this case, the number of composite images may be arbitrarily set by the user, or may be automatically set by an algorithm prepared by the camera 100 in advance.

(5) In the above-described embodiment, an example has been described in which the control device 104 performs gain correction by determining a gain correction amount to be applied to each post-development composition image in accordance with the number of post-development composition images. However, the control device 104 may determine the gain correction amount to be applied to each post-development composition image based on the shooting conditions and the subject.

(6) The control device 104 may perform the following processing in order to further enhance the effect of rendering the composite image. For example, in order to produce an effect that is characteristic of the composite image, the distance at which the focus is adjusted for each shot may be changed during pre-capture shooting. At this time, the type of the main subject and the type of the shooting scene may be determined before pre-capture shooting, and the defocus amount may be made variable according to the determination result. Further, the defocus amount may be minimized at the timing of fully pressing the release button. Alternatively, the control device 104 may analyze the composite image and perform image processing according to the analysis result. For example, the control device 104 may analyze the gradation of the composite image and adaptively perform gradation correction processing. Alternatively, the atmosphere of the composite image may be analyzed, and a blurring process may be performed by adaptively applying a digital filter. Further, the control device 104 may analyze the saturation of the composite image and perform saturation enhancement processing.

  Note that the present invention is not limited to the configurations in the above-described embodiments as long as the characteristic functions of the present invention are not impaired. Moreover, it is good also as a structure which combined the above-mentioned embodiment and a some modification.
