Description

  The present invention relates to an imaging apparatus, an imaging processing method, and a program that include an imaging unit that captures an image of a subject.

  In general, an imaging device such as a digital still camera or a video camera has a self-timer shooting function, and the subject is out of the shooting range because the photographer becomes a subject when shooting with the self-timer shooting function. In other words, framing or the like has to be performed in the state of being out of frame, which is often a major cause of shooting failure. Therefore, conventionally, when the photographer (subject) recognizes that the photographer (subject) has entered the frame by the face recognition function after pressing the shutter during the self-timer photographing, a technique has been adopted in which the subject (person) is focused before photographing. It is disclosed (see Patent Document 1).

Hereinafter, this embodiment of the present invention will be described with reference to FIGS.
This embodiment exemplifies a case where the present invention is applied to a digital camera as an image pickup apparatus, and FIG. 1 is a block diagram showing basic components of the digital camera.
An imaging device (digital camera) is a compact camera or single-lens reflex camera that can capture still images as well as moving images. In addition to basic functions such as the imaging function and timekeeping function, it is delayed from the shutter pressing operation. It has a self-timer function that starts shooting, a face recognition autofocus function that recognizes the face of a subject (person) and focuses the subject. The control unit 1 operates by supplying power from the power source unit (secondary battery) 2 and controls the overall operation of the imaging apparatus according to various programs in the storage unit 3. A CPU (Central Processing Unit) and a memory (not shown) are provided.

  The storage unit 3 includes, for example, a ROM, a flash memory, and the like, and stores a program and various applications for realizing the present embodiment in accordance with operation procedures shown in FIGS. A program memory 3a, and a work memory 3b for temporarily storing various information necessary for the operation of the imaging apparatus (for example, a flag, a self-timer measurement time). The storage unit 3 may include a removable portable memory (recording medium) such as an SD card or an IC card, and is connected to a network via a communication function (not shown). The state may include a storage area on a predetermined server device side.

  The operation unit 4 includes a mode change key 4a for switching a shooting mode (self-timer shooting mode, continuous shooting mode, etc.), a playback mode for playing back a shot image, and the like as a push button type key. In addition, a shutter key 4b for instructing the start of shooting and various keys (not shown) for setting shooting conditions such as exposure and shutter speed are provided. The control unit 1 is operated from the operation unit 4. In accordance with the input operation signal output corresponding to the key, for example, a mode change process, a shooting process, a shooting condition setting process, and the like are performed.

  Although not shown, the imaging unit 5 constitutes a camera unit capable of photographing a subject with high definition by forming a subject image from an optical lens on an imaging element (CCD, CMOS, etc.). (For example, a zoom lens), an image sensor, a strobe, various sensors, an analog processing unit, and a digital processing unit. The imaging unit 5 can capture a moving image in addition to a still image. The photoelectrically converted image signal (analog value signal) is subjected to color separation and gain adjustment for each RGB color component. After being converted, it is converted into digital value data. The digitally converted image data is subjected to color interpolation processing (demosaic processing) and is displayed in full color on the touch display unit 6. In the present embodiment, autofocus processing (AF processing), exposure adjustment processing (AE processing), auto white balance adjustment processing (AWB), image compression processing, image restoration processing, and the like can also be executed.

  The touch display unit 6 has a configuration in which a touch panel 6b is stacked on a display panel 6a. The display panel 6a is, for example, a high-definition liquid crystal display or an organic EL display having screens having different aspect ratios (width 4: height 3). On the Electro Luminescence) display, it becomes a monitor screen (live view screen) that displays a captured image (live view image) or a playback screen that plays back a captured image. The touch panel 6b constitutes a touch screen that detects a position touched by a photographer's finger and inputs coordinate data, and employs, for example, a capacitance method or a resistance film method. Other methods may be used. The speaker 7 generates a shutter sound when the shutter is pressed, or generates an alarm sound under a predetermined condition during self-timer shooting.

2 (1) to (4) are diagrams for explaining the simulation display in the self-timer photographing mode.
Here, the simulation display is a simulation display performed on the live view screen on the touch display unit 6 prior to the shooting in a state where the mode is switched to the self-timer shooting mode. Even when (actual subject: photographer) is out of the photographing range (out of frame), a live view image in a state where the focus is set on the subject is displayed by simulation. In order to perform such a simulation display, in this embodiment, a virtual subject of any size is synthesized and displayed on the touch display unit 6 in the live view screen before the self-timer shooting is performed. The virtual subject is, for example, a whole-body image of a real subject (photographer), and is an image (whole-body image) cut out in a human form from a photographed image obtained by photographing the real subject or a model (human type) imitating a real subject. Data such as illustration images (whole body images).
Further, any other simple shape may be used as long as the position and area size occupying within the shooting angle of view are known.

  2 (1) to 2 (4) are diagrams showing processing steps until simulation display is performed in the self-timer photographing mode. FIG. 2A is a diagram showing a thumbnail screen in which various images read from the storage unit 3 for arbitrarily selecting a virtual subject are displayed as a list of thumbnail images on the touch display unit 6. When a position (area) where a desired image is displayed is touched with a finger or the like from the list screen (thumbnail screen), the control unit 1 selects and designates the image as a virtual subject creation image, A desired virtual subject is created by cutting out a human figure (whole body image) from the selected image and enlarging or reducing it. FIG. 2B is a diagram showing a live view screen displayed on the touch display unit 6 in the self-timer shooting mode, and shows a frame-out state in which the photographer (real subject) is out of the shooting range. Yes.

  FIG. 2 (3) is a view showing a composite image display screen when the virtual subject selected in FIG. 2 (1) is arranged and compositely displayed in the live view screen shown in FIG. 2 (2). In a state where the virtual subject is composited and displayed on the live view screen, the control unit 1 calculates the subject distance when shooting a specific real subject and sets the focus position to the calculation result (subject distance). At the same time, the calculation result (subject distance) is numerically displayed on the live view screen. FIG. 2C shows a state in which “6.6 m” is displayed as a subject distance as a guide.

  FIG. 2 (4) is a diagram showing a composite image display screen when the subject distance is changed by enlarging or reducing the virtual subject by a touch operation (for example, a zoom-in operation) with two fingers, for example. . That is, in the state where the composite image display screen is displayed, when a change in the display position or display size is instructed by a touch operation on the virtual subject in the screen, the control unit 1 displays the display position of the virtual subject. Processing to adjust the display size is performed. In this case, the control unit 1 changes the subject distance in accordance with the change in the display size of the virtual subject, further changes the focus position in accordance with the change in the subject distance, and changes the numerical display in the live view screen. . The illustrated example is a case where the subject distance is changed from “6.6 m” to “4.0 m” by enlarging the entire virtual subject (whole body).

3 (1) to 3 (4) are diagrams for explaining how to calculate the subject distance.
FIG. 3A illustrates the angle of view in the live view display state, the focal length of the photographing lens, and the frame size of the image sensor (for example, CCD). In the figure, “θl” is the angle of view, and “xl "" Indicates the focal length of the lens, and "y" indicates the frame size (height) of the image sensor. FIG. 3 (2) shows the size of the real subject, the subject distance when photographing the real subject, and the photographing area at the position of the subject distance when the virtual subject is compositely displayed (inserted display) on the live view screen. In the figure, “vy” is the size of the actual subject (height: height), “vx” is the subject distance from the principal point of the photographing lens when photographing the real subject, and “py” "" Indicates the size (height) of the shooting area (shooting range) at the position of the subject distance. Note that the height (height) vy of the actual subject is an input value input in advance by a user operation.

FIG. 3 (3) shows the size of the virtual subject and the size of the live view screen in the live view screen when the virtual subject is synthesized and displayed (inserted display) in the live view screen. In the figure, “gvy” indicates the display size (height) of the virtual subject in the live view screen, and “gpy” indicates the size (height) of the live view screen. Note that the height gvy of the virtual subject in the live view screen is a measurement value measured by analyzing the live view image. FIG. 3 (4) shows an equation for calculating the subject distance vx from the principal point of the photographing lens, and the subject distance vx is obtained according to the following equation.
py = vy × gpy / gvy
tan (θl / 2) = y / 2xl = py / 2vx
Therefore, vx = xl × py / y

Here, the frame size (height) of the image sensor: y = 1 / 2.3 type = 4.6 mm
Focal length of zoom lens during live view display (f = 5-35 mm): f = 15 mm
Real subject size (height): vy = 170 cm = 1700 mm
Live view screen size (height): gpy = 480 pixels Display size (height) of virtual subject in live view screen: gvy = 400 pixels
py = 1700 × 480/400 = 2040
vx = 15 × 2040 / 4.6 = 6652.2 mm
Subject distance vx = 665.2 cm

  Next, the operation concept of the imaging apparatus in the present embodiment will be described with reference to the flowcharts shown in FIGS. Here, each function described in these flowcharts is stored in the form of a readable program code, and operations according to the program code are sequentially executed. Further, it is possible to sequentially execute the operation according to the above-described program code transmitted via a transmission medium such as a network. In other words, the operation unique to the present embodiment can be executed using the program / data supplied from the outside via the transmission medium. 4 to 6 are flowcharts showing an outline of the operation of the characteristic part of the present embodiment in the entire operation of the imaging apparatus. When the flow of FIGS. Return to the main flow (not shown).

FIG. 4 is a flowchart showing a preparatory process related to self-timer shooting, which is started when a setting mode related to self-timer shooting is selected from various setting modes by a user operation.
This preparation process is a process for specifying a virtual subject for simulation display. First, a process menu screen is displayed on the touch display unit 6 (step A1). In this menu screen, “1”: whether a virtual subject is arbitrarily created, “2”: whether a previously created virtual subject created by the user is used, or “3”: preset virtual A menu item for selecting whether to use the subject, and when an arbitrary item is selected from among the menu items, the selection item is “1”: is an item instructing creation of a virtual subject ( Step A2), “2”: It is checked whether the item is an instruction to use the created virtual subject (Step A3).

  Now, “1”: When a menu item for instructing the creation of a virtual subject is selected (YES in step A2), thumbnails are selected with various images read from the storage unit 3 as selection candidates as shown in FIG. When a list is displayed on the screen (step A4) and an image desired by the photographer is selected and designated from the thumbnail screen (step A5), the process proceeds to a process of creating a virtual subject from the selected image (step A6). . In this case, a desired virtual subject is created by cutting out or enlarging or reducing a whole body image of a person from the selected image. When the virtual subject is created in this way, the process proceeds to a process of inputting the number data (height data) of the real subject (photographer) by the user operation (step A7). Then, the created virtual subject and the input height data are associated with each other and stored in the storage unit 3 as information for self-timer shooting (step A8).

  “2”: When a menu item for instructing the use of the created virtual subject is selected (YES in step A3), the created virtual subject is read from the storage unit 3 (step A9) and associated therewith. The size data (height data) of the virtual subject is read (step A10). When any other menu item is selected (NO in step A3), “3”: the menu item instructing the use of the set virtual subject is selected, and the actual subject is set as a preset image. A model image imitating a person or a human figure image of a general person is read out as a virtual subject (step A11), and size data (height of the virtual subject) set in association with a model image of a real subject or a human figure image of a general person Data) is read (step A12). In this case, the height data corresponding to the model image of the real subject is the actual height of the real subject, but the height data corresponding to the humanoid image of the general person is average height data. Note that a plurality of human-type images and height data of general persons are prepared corresponding to sexes and the like, and the human-type and height data close to the actual subject (photographer) are selected from among them.

5 and 6 are flowcharts that are started when the mode is switched to the self-timer shooting mode.
First, the control unit 1 starts a live view display operation for displaying an image captured by the imaging unit 5 as a live view image on the touch display unit 6 (step B1 in FIG. 5). Then, the virtual subject specified in the above-described preparation process and the size data (height data) of the virtual subject are acquired (step B2), and the virtual subject is arranged in the live view screen of the touch display unit 6 and displayed in combination (simulation). Display) (step B3). In this case, the virtual subject is displayed in an initial size at a predetermined initial position.

  Thus, in a state where the virtual subject is initially displayed in the live view screen (simulation screen), the subject distance is calculated according to the above-described calculation formulas “py = vy × gpy / gvy, vx = xl × py / y”. (Step B4). Here, the size (height) of the real subject: vy = 1700 mm, the size (height) of the live view screen: gpy = 480 pixels, the display size of the virtual subject in the live view screen (initial size): gvy = 400 Assuming the pixel, as described above, py = 1700 × 480/400 = 2040, vx = 15 × 2040 / 4.6 = 6652.2 mm, and vx = 665.2 cm. The calculated subject distance vx is displayed as a numerical value (guidance display) in the simulation screen (step B5), and the position is set as the simulation focus position in the imaging unit 5 so that the subject distance is in focus (step B6). ).

  Next, it is checked whether a touch operation has been performed on the simulation screen (step B7), whether a shutter pressing operation has been performed (step B10), or whether other operations have been performed (step B10). B11). If no operation is performed (NO in step B11), the process returns to the above-described step B7 and waits for an operation. If any other operation is performed (YES in step B11), the operation is performed. As processing, for example, processing such as exposure adjustment and zoom adjustment (step B12) is performed, and then the processing returns to step B7 described above. Note that when an operation for canceling the self-timer photographing mode is performed as another operation, the flow of FIGS. 5 and 6 is omitted (not shown).

  Now, when a touch operation is performed on the simulation screen (YES in step B7), processing for adjusting the display position and display size of the virtual subject is performed according to the type of touch (step B8). Here, when changing the display position of the virtual subject, a slide operation (tracing operation) to move to a desired position while touching the display area of the virtual subject is performed, and the display size of the virtual subject is changed. Includes a multi-touch operation (zoom-in operation) for moving each finger in the direction of opening each finger while touching the display area of the virtual subject with two fingers, or a multi-touch operation for moving the two fingers in the closing direction ( Zoom out).

  When the display position and display size of the virtual subject are arbitrarily changed in this way, the control unit 1 detects the display size (height) by analyzing the changed virtual subject (step B9). Then, returning to the above-mentioned step B4, a new subject distance is calculated based on the changed display size of the virtual subject, and the calculated subject distance vx is guided and displayed in the simulation screen (step B5). The position is set as the simulation focus position in the imaging unit 5 so that the distance is in focus (step B6). In this case, by enlarging the entire virtual subject (whole body), the subject distance can be changed from “6.6 m” to “4.0 m” as shown in FIG. Is changed. Hereinafter, every time the display size of the virtual subject is changed, the above-described operation is repeated (steps B4 to B9).

  On the other hand, when the shutter pressing operation is performed in the self-timer shooting mode (YES in step B10), the flow proceeds to the flow of FIG. 6 and the virtual subject in the live view screen is deleted (step B13), and the self-timer measurement operation is performed. Is started (step B14). Then, it is checked whether the face recognition autofocus function is set to an operable on state (step B15). If it is set to an off state (NO in step B15), the process proceeds to step B21. Is set (YES in step B15), the face recognition autofocus function is operated (step B16). In this case, an actual subject framed in the live view screen is recognized based on recognition information (a person's face image and its characteristic information) registered in advance, and the real subject recognized by this face recognition is recognized. Autofocus.

  Next, the autofocus position is compared with the focus position at the time of the simulation display described above to calculate the difference (absolute value) (step B17), and whether the difference is more than a predetermined value (for example, 30 cm). Check (step B18). If the difference is less than the predetermined value (NO in step B18), the focus position at the time of the simulation display is kept set, but if the difference is greater than or equal to the predetermined value (YES in step B18). Then, instead of the focus position at the time of the simulation display described above, an autofocus position is set in the imaging unit 5 (step B19). Then, an alarm sound is generated from the speaker 7 in order to notify that the frame-in position is not the correct position (step B20).

  Next, it is checked whether the self-timer has timed out (step B21). If it is before the time-out (NO in step B21), the real subject image in the live view screen is analyzed (step B22), and the real subject is in focus. It is checked whether or not it has moved beyond a predetermined value that affects the position (step B23). Now, when the actual subject is not moving, even if it is moved, if the amount of movement is less than a predetermined value (NO in step B23), the process returns to the above-mentioned step B21 and enters a standby state until the self-timer times out. When the actual subject has moved by a predetermined value or more (YES in step B23), the process returns to step B15 described above. In this case, if the autofocus is in an on state (YES in step B15), the above-described operation is repeated after autofocusing the moved real subject again. If a timeout is detected (YES in step B21), the imaging unit 5 performs a shooting process at the currently set focus position (step B24). Thereafter, the flow of FIGS. 5 and 6 is exited.

  As described above, in the present embodiment, the control unit 1 arranges and displays a virtual subject of an arbitrary size in the live view screen, and subjects a subject to be photographed based on the display size of the virtual subject. Since the distance is calculated and the focus position of the imaging unit 5 is set to the subject distance, even if the actual subject is out of the shooting range, the photographer must An image focused on the subject can be confirmed in advance, and a desired image can be accurately captured. As a result, it becomes effective at the time of self-timer shooting, and further, for example, when shooting only the background in advance to synthesize a subject such as a person later, an image that is not focused on the background ( This is also effective when shooting an image with a consciously blurred background.

  When the height of the real subject to be photographed is specified, the subject distance when shooting the actual subject based on the height of the virtual subject in the live view screen, the height of the real subject and the shooting angle of view is determined. Since the calculation is made, the subject distance for focusing on the position of the actual subject can be easily obtained.

  Since the height of the real subject to be photographed is input by a user operation, the height of the real subject can be specified accurately.

  Since any one of a plurality of real subjects whose heights are known in advance is selected by a user operation, the height of the real subject can be easily specified.

  Even if the real subject is out of the shooting range during self-timer shooting, if the frame is placed in the display position (substantially the same position) of the virtual subject, self-timer shooting that focuses on the real subject becomes possible, and shooting fails. Can be suppressed.

  If the difference between the autofocus position during the timer measurement operation of self-timer shooting and the focus position during simulation display is greater than or equal to a predetermined value, the autofocus position is substituted for the focus position during simulation display. Since the self-timer shooting is performed with the setting of 5, the shooting can be performed with the real subject in focus even if the position where the real subject is framed in is not the correct position.

  Compared the auto focus position during the timer measurement operation of self-timer shooting and the focus position during simulation display, and if the difference is greater than or equal to a predetermined value, a warning is output, so the real subject has entered the frame You can be informed that the position is not correct.

  At the time of autofocus, since the real subject in the live view screen is recognized and autofocused based on the recognition information registered in advance, the focus on the real subject that is the shooting target is more reliable.

  Since an image cut out from an image obtained by photographing an actual subject to be photographed is combined and displayed as a virtual subject in the live view screen, for example, a virtual subject can be generated from an image taken most recently. A more realistic simulation is possible.

  Since the model image data imitating the real subject to be imaged is displayed as a virtual subject in the live view screen, the work of creating the virtual subject is not necessary.

  Since the virtual subject is a full-body image of a person, when calculating the focal length based on the display size of the virtual subject, the display size can be used as the height.

  The calculated subject distance is displayed together with the virtual subject in the live view screen, so when the real subject enters the frame, the distance to the target subject can be determined using the displayed subject distance as a guide. Can be confirmed.

  In the above-described embodiment, the distance when photographing a real subject is calculated, but a table in which the distance to the subject and the size (height data) of the real subject are associated is stored. The distance for calculating the actual subject may be calculated based on the above.

In the above-described embodiment, the size (height data) of the actual subject is input, but for example, a preset average size (height) for Japanese men and women is used. May be.
Further, a plurality of virtual subjects to which the size (height data) of the actual subject is input may be registered and may be selected.

  In the embodiment described above, the whole body image of the person is used as the virtual subject, but it may be an image above the chest or a face image. In this case, the display size of the virtual subject may be the height above the chest or the height of the face image. In addition, the height of the actual subject may be the height above the chest or the height (length) of the face. Furthermore, the virtual subject may be a photographed image of the same person as the actual subject (real subject), a general human-type image, or an image of a pet or character, not limited to a person. Any desired image may be used as a virtual subject.

  In the embodiment described above, the autofocus position during the timer measurement operation of the self-timer shooting is compared with the focus position during simulation display, and if the difference is greater than or equal to a predetermined value, a warning sound is output. However, the warning may be made by lighting or blinking the lamp. In the above-described embodiment, the photographing is performed even when the difference is a predetermined value or more. However, only the warning may be output.

  In the above-described embodiment, the case where the present invention is applied to the self-timer shooting is shown. However, the present invention can be similarly applied to the case where the shooting state is confirmed by simulation display using the time until the person enters the frame.

  Further, in the above-described embodiment, the subject distance when the real subject is photographed after the virtual subject is arranged first is calculated. The virtual subject may be displayed at a size to be used. In this case, when a virtual subject corresponding to a specific real subject is displayed in the live view screen in which the image from the imaging unit 5 is displayed as a live view image, the subject distance when shooting the specific real subject is set. Based on this, the display size of the virtual subject corresponding to the real subject may be calculated, and the virtual subject having the calculated display size may be arranged on the live view screen for composite display. As described above, the same effect as that of the above-described embodiment can be obtained even if the subject distance when photographing the real subject is determined first, the size of the virtual subject is calculated, and the virtual subject is synthesized and displayed. A person can check in advance an image focused on the subject, and can accurately capture a desired image.

  In the above-described embodiment, the present invention is applied to a digital compact camera. However, a digital single-lens reflex camera may be used, and a personal computer with a camera function, a PDA (personal portable information communication device), It may be a music player or an electronic game.

  Further, the “apparatus” and “unit” shown in the above-described embodiments may be separated into a plurality of cases by function, and are not limited to a single case. In addition, each step described in the above-described flowchart is not limited to time-series processing, and a plurality of steps may be processed in parallel or separately.
