Referring to FIG. 1, the composition setting photographing apparatus according to the present invention may be configured by only the photographing apparatus 100 to adjust the photographing direction by holding the hand, but in this case, only some of the actions described in the present invention are performed. As such, as shown in the embodiment of the present invention includes a cradle 200 that can adjust the pan (Pan) and tilt (Tilt) of the photographing apparatus 100 or the cradle 200 or the imaging device ( It is preferable to configure integrally with 100). In the following description will be described an embodiment of the present invention comprising a cradle 200. In addition, the cradle 200 for adjusting the pan and tilt is controlled by the photographing apparatus to communicate with the photographing apparatus in a wired or wireless manner to adjust the pan and tilt, and thus a detailed description thereof will be omitted. In addition, the photographing apparatus 100 is a digital device having a camera function. For example, the photographing apparatus 100 may be a camera or a mobile communication terminal having a camera function. Equipped with a cradle 200 is satisfied if it can be configured to adjust the pan and tilt.

The photographing apparatus includes a camera unit 120, a display unit 130, an input unit 140, a storage unit 150, a photographing guide unit 160, and a controller 110. In addition, the controller 110 controls the pan tilt driver 210 of the cradle 200 to adjust the shooting direction.

The camera unit 120 is configured to enable not only an operation of obtaining an image by capturing an image, but also a preview view operation of outputting an image to the display unit 130 before capturing, and a zoom operation. do.

The display unit 130 outputs the preview view image to the user, and outputs the recommended photographing composition or recommendation position, which will be described later, on the preview view image. Although not shown in FIG. 1, an image processor (not shown) for signal processing digital image data and outputting the same to the display unit 130 is also included.

The input unit 140 is a component that is manipulated by a user and enables an input required to perform various operations prepared for a camera function as well as operations for photographing operation and image storing operation. In addition, the input unit 140 should also enable a variety of operations for the present invention. On the other hand, by configuring the display unit 130 as a touch screen, some or all of the operations to be made in the input unit 140 may be made in the display unit 130.

The storage unit 150 stores the captured image 153. In addition, according to the present invention, the storage unit 150 also stores various types of recommended photographing composition 151, recommended position 152, and preset feature information of the main subject.

The main subject may be, for example, a friend or himself who wants to photograph in the background of a landscape or a place where a large number of people are gathered as a main subject to be photographed. In the embodiment of the present invention, it is set as a person, and is divided into body parts including the face, the whole body, and the face so as to select the desired shape. As another example of the object that can be set as the main subject above, a specific object, a pot planted with a plant, or a car may be used. However, as described below, when the photographing composition is determined according to the direction of the main subject, constraints are applied. However, if the rules for defining the direction can be determined, the other examples can be designated as the main subjects.

The feature information of the main subject is basic information necessary to recognize the main subject in the preview image.

Prior to describing the recommended photographing composition 151, a photographing composition is a term generally used in the field of a camera. Briefly describing a process of obtaining a photographing composition, various components such as a point, a line, or a color in an image image are described. By selecting the main edges estimated by the association between the extracted components and the extracted components, the pattern consisting of the main edges can be determined as the photographing composition. Accordingly, the photographing composition may be determined by the shape of the subjects and the arrangement of the subjects that can be recognized by recognizing the image.

As shown in the examples of FIGS. 2 and 3, the photographing composition is formed in various forms according to a photographing region, a photographing direction, a photographing range, and may be extracted from a background image not including a person, but a background including a person. It may be extracted from the image. In addition, such a photographing composition not only influences the satisfaction of the image taken by the camera, but also allows the user to select which position the main subject is better to obtain a satisfactory composition.

In addition, according to the present invention, the recommended photographing composition 151 employs a photographing composition obtained from a background image having an optimal composition among these photographing compositions. In this case, the recommended photographing composition 151 is a photographing composition of a background image excluding the main subject. When the subject priority processor 112 is operated as described below, the photographing composition with the main subject is taken. That is, the photographing composition, which is used as a reference for capturing an image at an optimal composition, by the subject priority processor 112 is a composition including the positions of main subjects in the recommended photographing composition.

The recommended position 152 is the position of the main subject to obtain an optimal composition as a whole in accordance with the recommended photographing composition. The recommended position is determined in advance to an appropriate position according to the pattern of the recommended photographing composition.

4 is an exemplary view of the recommended position, which is a preliminary recommended position of the intersection of the intersections of the lines 1 and 2 dividing the image into three horizontally and vertically, respectively. (3). In detail, each of the preliminary recommended positions 3 shown in FIG. 4 is defined for each recommended photographing composition, and when subdivided into the body including the face, the whole body, and the face as described above, the subdivided main subjects are different from each other. You can also set a point. On the other hand, FIG. 4 is an exemplary diagram and is not limited thereto. The recommended position may be set to a position different from the preliminary recommended position according to the pattern of the recommended photographing composition.

Next, the photographing guide unit 160 may be configured as a sound or a lamp, or may be configured as an output screen of the display unit 130 as a configuration for guiding a signal to be recognized by a person. And, functionally, when guiding the movement of the photographing target selected as the actual main subject as described below, it may operate as a direction guide.

The controller 110 controls a preview view operation, a photographing operation, a display operation, and an image storing operation according to an operation of the input unit 140 by a user.

In addition, according to the present invention, the control unit 110 includes an image recognition unit 115, a composition determination unit 116, and a PTZ control unit 117, and a composition priority processor 111 that selectively operates according to an operation mode. ), A subject priority processor 112, a composition adding processor 113, and a video processor 114.

The image recognition unit 115 recognizes a scene through edge detection in the preview view image. In addition, the image recognition unit 115 recognizes the presence of the main subject in the preview image based on the feature information of the main subject stored in the storage unit 150, and if the main subject exists, the shape of the main subject The size and position are detected, and the size, position and direction of the face of the main subject are detected by the face recognition algorithm.

Also, when the main subject is detected, the image recognition unit 115 acquires a pattern consisting of the remaining edge components excluding the main subject, that is, the photographing composition excluding the main subject. In addition, the image recognition unit 115 may obtain a photographing composition for the original of the preview view image including the main subject selected from the preview view image.

The composition determiner 116 compares a photographing composition excluding a main subject in the image recognition unit 115 with a plurality of recommended photographing compositions 151 stored in the storage unit 150, and shows the highest similarity. Find a composition. In addition, the composition determiner 116 generates a photographing composition in which the recommended photographing composition 151 and the recommendation position 152 stored in the storage unit 150 are associated with each other, and each photographing composition generated Compared to the photographing composition of the preview view image (the entire preview image without excluding the main subject), the photographing composition (the photographing composition associated with the recommended photographing composition and the recommended position) is found. Thereby, the recommended photographing composition having the highest similarity can be obtained when reflecting the main subject.

The PTZ controller 117 is in charge of adjusting the zoom of the camera 120 and adjusting the pan and tilt of the cradle 200.

The image recognition unit 115, the composition determination unit 116 and the PTZ control unit 117 is selectively adopted by the above-described processors (111, 112, 113, 114) to operate.

The above-described

processors

111, 112, 113, and 114 will be described with reference to a flowchart of the composition setting photographing method shown in FIGS.

5 is a view showing an operation mode of a photographing method comprising a composition setting photographing apparatus according to an embodiment of the present invention. Referring to FIG. 5, an operation mode selectable by the operation of the input unit 140 includes a still image shooting mode S200, a video shooting mode S300, and a shooting sphere addition mode S400. In the still image capturing mode (S200), the image may be divided into a composition-priority photographing mode (S210) and a subject-priority photographing mode (S220).

FIG. 6 is a flowchart illustrating an operation of the still image capturing mode S200, and operates a processor selected from a composition priority processor 111 and a subject priority processor S112.

In the still image capturing mode (S200), a preview image is output to the display unit 130 (S201), and a mode is selected (S202). The mode selection menu is a composition-priority shooting mode (S210) and a subject-priority shooting mode (S220). When the composition-priority shooting mode (S210) is selected by the input unit 140, the composition-priority processor 111 is operated to construct the composition as follows. First, the shooting mode (S210) is performed.

First, the composition priority processor 111 operates the image recognition unit 115 to recognize a preview view image (S211). At this time, the recognition of the image is a process of checking whether the main subject is recognized in the preview image based on the feature information of the main subject, extracting the main subject when the main subject is recognized, and main subject difference when the main subject is recognized. Extracting the photographing composition of the preview image and excluding the photographing composition of the preview image as it is if the main depth of focus is not recognized.

Here, the main subjects to be excluded when the photographing composition is extracted are preferably recognized by the main subjects and displayed on the display unit 130 so as to be directly selected by the user. In other words, the main subjects not selected by the user are not of interest and are only included in the photographing composition as the background. In addition, the main subject to be excluded can be specified as a range in the preview image. Accordingly, when a plurality of main subjects are selected individually or selected by range designation, the selected area is treated as a main subject group that substitutes one main subject.

In addition, when extracting the photographing composition according to the edge pattern appearing in the preview image, only the edge pattern longer than the length of the main subject recognized in the preview image among the edge patterns is selected, and the photographing composition is selected using only the selected edge pattern. It is preferable to extract. The length of the main subject, which is the criterion for selecting the edge pattern, is the length of the main subject or the preset length that the user selects and recognizes as described above.

In addition, even if the edge pattern is smaller than the length of the main subject, if the pattern has a color that contrasts sharply with the surrounding color, it will greatly affect the shooting composition, so that the color contrast with the surrounding color will be larger than the preset contrast level. If it is, it is desirable to include it in the photographing composition.

In addition, since the main subject in the embodiment of the present invention as a person, it is also possible to select any one area of the body, including the face, the whole body and the face.

Next, the composition priority processor 111 operates the composition determination unit 116 to compare the photographing composition extracted from the preview image with each of the recommended photographing composition 151 stored in the storage unit 150, and the comparison result. In step S212, the recommended photographing composition having the highest similarity is selected.

Next, the composition priority processor 111 outputs the selected recommended photographing composition to the display unit 130 (S213), and checks the recommendation position corresponding to the selected recommendation photographing composition in the storage unit 150 to display the display unit 130. In step S214, the recommended photographing composition and the recommendation position are superimposed on the preview image.

Accordingly, when the photographing device is held in the hand and the photographing direction is changed or the zoom of the camera 120 is adjusted by the manipulation of the input unit 140 (S217), the recommended photographing composition is reselected according to the changed preview image. (S218) Since the re-selected recommended shot composition and the re-selected recommended shot composition recommended position is output to the display unit 130 (S219), the user adjusts the shooting direction or zoom while watching the display unit 130 to preview image. Can be approximated to the recommended shooting composition. After the user approximates the preview image to the recommended photographing composition, the user performs an operation of photographing the object of interest in accordance with the recommended position.

In the process of photographing, it is preferable to guide to move toward the recommended position. To this end, it is preferable to have a direction guide for guiding the direction of the recommended position using a sound or a display lamp. The direction guide not only guides the direction in which the main subject of interest should move, but also detects when the main subject is in the recommended position in the preview image and guides the start of shooting. The photographing operation may be delayed for a predetermined time after the operation of controlling the camera unit 120 to automatically photograph, the manual photographing operation by the operation of the input unit 140 or the remote controller, or the operation of the input unit 140 or the remote controller. One operation may be performed during the photographing operation, and the photographed image is stored in the storage unit 150.

On the other hand, when the photographing apparatus is mounted on the cradle 200 to be able to operate the pan tilt drive unit 210 of the cradle 200, it performs a composition recommendation automatic mode (S215, S216). At this time, the composition recommendation automatic mode is to scan the periphery of the main subject (S215) by adjusting the Pan, Tilt and zoom (S215), and the preview image that changes every time as the periphery is scanned The composition is compared with the recommended photographing composition of the storage unit 150, respectively. As a result of comparison, the recommended photographing composition having the highest degree of similarity is selected and the pan, tilt, and zoom states are memorized and the pan tilt driver 210 and the camera 120 are zoomed (S216). In this way, after performing the automatic composition recommendation mode (S215, S216) guides to the recommended position and photographing after guiding the start of shooting. The guide of the recommended position, the guide of the start of shooting, and the shooting operation can be the same as the manual method described above.

FIG. 7 is a flowchart illustrating an operation of the subject priority photographing mode S220, and is performed by operating the subject priority processor 112.

The subject priority processor 112 selects a main subject in the preview image, and finds an optimum photographing composition having the selected main subject as a recommended position. The operation of the subject priority processor 112 that is different from the composition priority processor 111 generates a photographing composition including the main subject without excluding the main subject from the preview image, and includes a recommended position in comparing the similarities. Similarity is compared with the recommended photographing composition.

The subject priority photographing mode S220 by the operation of the subject priority processor 112 will not be repeated with the description of the composition priority processor 111 and will be briefly described.

First, the object priority processor 112 recognizes a preview view image and extracts a photographing composition (S221). At this time, the extracted shooting composition is the shooting composition of the original preview image without the subject to be excluded, and the main subject recognized in the preview view image is recognized as an outline or a range line on the preview view image of the display 130. To be able.

Next, the subject priority processor 112 receives a main subject from the preview image (S222). At this time, the selected main subject is a target to be photographed with a focus, and may be designated as a plurality or range.

Next, the subject priority processor 112 selects an optimal recommended photographing composition having the position of the selected main subject as the recommended position (S223). In this case, by comparing the shooting composition generated by including the recommended position in the recommended shooting composition stored in the storage unit with the shooting composition of the preview image (extracting the composition extracted without the subject), the recommended shooting composition having the highest similarity is selected. do.

Next, the subject priority processor 112 outputs the selected recommended photographing composition to the display unit 130, and also outputs a corresponding recommendation position to be superimposed on the preview image (S224).

If the shooting direction or zoom is changed (S227), the preview image is also changed, so that the process of comparing the recommended composition including the recommended position with the photographing composition of the preview image is repeated, and the recommended photographing composition is also repeated. In operation S228, the recommended photographing tool displayed on the display 130 is also changed (S229). Accordingly, the user may change the photographing direction or the zoom until the preview view image approximated to the recommended photographing composition is captured, and the image may be photographed in the approximated state to obtain an image suitable for the photographing composition.

On the other hand, the subject-first shooting mode (S220) also has a composition recommendation automatic mode (S225, S226) similar to the composition recommendation automatic modes (S215, S216) of the composition-first shooting mode (S210). The composition recommendation automatic modes S225 and S226 of the subject-priority photographing mode S220 find a recommended photographing composition in which the similarity is the highest by adjusting pan, tilt, and zoom in a state where the photographing apparatus is mounted on the holder 200, and the found photographing recommendation. Adjust the degree of similarity to the composition to the values of pan, tilt, and zoom. At this time, the process of finding the recommended photographing composition is compared with the photographing composition of the original preview image without exclusion of the subject as described above, and the photographing composition including the recommended position in the recommendation photographing composition, indicating that the similarity is the highest. Select the recommended shot composition.

Since the recommended position of the recommended photographing composition found in the subject-priority photographing mode S220 and the position of the main subject may not exactly match, it is also possible to guide the main subject to move slightly before shooting.

On the other hand, in the case where the person is the main subject, making the surface of the face facing in the direction wider than the surface in the opposite direction improves the shooting composition. Accordingly, the image recognition unit 115 recognizes the direction in which the face faces when recognizing the main subject as the person in the preview image, and the composition determiner 116 selects the main subject when selecting the recommended photographing composition. It is preferable to select the recommended photographing composition having the highest similarity among the recommended photographing compositions, in which the face in the direction toward the face is relatively wider than the surface in the opposite direction.

8 is a flowchart illustrating an operation of the video shooting mode S300, and is implemented by operating the video processor 114.

The video processor 114 recognizes the main subject in the preview view image and outputs the preview image to the display unit 130, and displays the recognized main subject as an outline or a range line. Main subject selection step (S320) to be selected by the user, the area setting step of setting the area of the main subject selected by the user (S330), and tracking shooting step of tracking the main subject until the shooting end operation (S345) ( 340).

Here, the number of main subjects selected may be plural, and identification information is separately extracted for identification with a subject present in the preview image but not selected by the user. Accordingly, the selected main subject can be tracked and photographed separately from the unselected subject. The identification information of the selected main subject may be, for example, a feature or color of a shape.

Meanwhile, the main subject selected by the user in the preview image is not limited to a subject that can be recognized based on the feature information stored in the storage 150. In other words, when a user selects a specific object from the preview image output on the display unit 130, the controller 110 recognizes the selected object as the image recognition unit 115 to determine the main subject and the main subject. When the feature information of the object is extracted and tracked, the tracking is performed based on the feature information. In this case, the feature information is extracted and tracked, for example, a case of tracking a moving object such as a soccer ball, an animal, an insect, an airplane, or a bicycle.

And, the area setting of the main subject is to set the position and the occupying range of the main subject in the preview image. The area of the main subject is set so that a moving picture is photographed relatively wider than the face in the face direction or the body direction of the main subject.

Tracking and photographing the main subject (S340) may include capturing and analyzing the main subject in the preview image and analyzing the area and state (shape in the pre-view image) (S341). Area correction step (S342, S343) for selectively modifying the area according to the control, and pan, tilt and zoom adjustment, including a PTZ control step (S344) to track the main subject (S344), and tracking to shoot until the end of shooting Continue the process.

In the capturing and analyzing step S341, the main subject selected by the user is captured in the preview view image, and the position and range occupied in the preview view image are analyzed. If a plurality of main subjects are selected, the groups are grouped according to the distance between the main subjects, and the sizes of the main subjects are also analyzed. In addition, the direction in which the main subject faces (movement direction or face direction) is also analyzed.

In the region correcting step (S342, S343), by checking the result of the capturing and analyzing step (S341), it is determined whether the area of the main subject can be adjusted to the region set in the region setting step (S330), The control proceeds to the next PTZ control step (S344) (S342), and if it is impossible to reset, after resetting the area (S343), the control proceeds to the next PTZ control step (S344).

Resetting the main subject area (S343) occurs when the PTZ of the photographing device cannot adjust the main subject area to the set area. The main subject is too close or too far to zoom in or out. When resetting the area and when tracking a plurality of main subjects, the PTZ of the photographing apparatus cannot capture all the main subjects as captured images, and thus resetting the area so that only some main subjects are photographed. It is divided into the case of resetting the area according to a predetermined rule beyond the control range of PTZ.

In the case where only some of the main subjects are reset to the area among the plurality of main subjects, the grouping performed in the capturing and analyzing step (S341) sets a group of a large number of the main subjects to set the photographing composition. When the number of main subjects included in each group is the same, the photographing structure is adjusted by resetting the group to which the largest main subject on the image belongs.

If the main subject is out of the control range of the PTZ of the photographing apparatus, for example, the main subject is taken away and the point is taken at a wide angle to increase the probability of the main subject being captured again.

Of course, the area of the main subject set initially is memorized, and the area is adjusted to the initial setting when it becomes the PTZ control range of the photographing apparatus.

The PTZ adjustment step (S344) is taken by adjusting the PTZ (pan, tilt, zoom) in two ways according to the processing result in the region correction step (S342, S343).

The first method is a method of adjusting the PTZ to maintain a constant position and occupancy range of the main subject in accordance with the set area, when the area is adjustable in the area setting step (S330). In the first method, when tracking a plurality of main subjects, the range (four-sided edges) occupied by the plurality of main subjects is made constant in accordance with the setting area, and the center point of the range is also set in the setting area. However, the center point of the main subject, i.e., the position is adjusted so that a moving image is photographed relatively wider than the face in the face direction or the body direction of the main subject, so that the direction of the face or body of the moving main subject is captured. Even if it changes in the middle, it adjusts to the shooting composition.

In the second method, the PTZ is taken to adjust the area of the main subject to the reset area. In the second method, the motion picture is captured so that the face of the main subject or the face of the main subject is relatively wider than the face of the opposite direction. If the number of main subjects is two or more, the direction of the largest main subject is adjusted or the average value of the main subjects is aligned.

9 is an operation flowchart of the photographing composition adding mode S400, which is performed by operating the composition adding processor 113.

Shooting composition adding mode (S400) by the composition adding processor 113, the still image of the video taken and stored in the still image shooting mode (S200) or the video taken in the video recording mode (S300) Step S410, recognizing the imported image to extract the shooting composition (S420), inputting the recommended position according to the shooting composition (S430) and storing the shooting composition and the recommended position in the storage unit 150 The step S440 is added to the previously stored recommended photographing composition and the recommended position. The composition adding processor 113 further stores the recommended photographing composition and the recommendation position desired by the user, so that the composition adding processor 113 is used as the recommendation photographing composition when the still image photographing mode is performed.

In describing the embodiment of the present invention, the user operates the input device 140 provided in the photographing apparatus 100 to operate the photographing apparatus 100, but the short range communication module or the remote communication module uses the photographing apparatus 100. ) To operate the photographing apparatus 100 by using an external control device (not shown) such as a remote control, a mobile communication terminal or a remote terminal capable of communicating with the communication module.
