Description

  The present invention relates to an image processing apparatus, an image processing method, and an image processing program for creating a moving image from three-dimensional CG data.

  As image content is digitized, the same image content is increasingly likely to be viewed on displays of various screen sizes, such as a theater-type large screen or a small display of a small portable terminal. However, even if the image content is exactly the same, when using a large screen and when using a small display such as a personal computer or a mobile terminal, the intensity of stimuli such as a sense of presence and a sense of motion can be felt differently. It is known. In particular, in the case of video that emphasizes an immersive feeling such as experience-type video content, it is a big problem that the impression given to the viewer varies depending on the size of the viewing screen. In addition to the screen size, factors that affect the impression given to the viewer include physical characteristics such as the resolution of the display, and physical characteristics such as the age of the viewer.

  Therefore, in order to provide an optimal image for each viewing condition when viewing conditions are different, it is necessary to individually produce ideal image contents optimized for each viewing condition. For example, it is necessary to produce a plurality of video contents even for the same content, such as creating video contents for a small display such as a home TV separately from video contents created for a large screen such as a movie theater. is there.

  However, since there are a wide variety of combinations of viewing conditions, it is necessary for video producers to spend a great deal of time and effort to individually produce ideal image content optimized for each viewing condition. As a result, the production cost of the image content increases. Therefore, it is difficult to actually implement the separate creation of the image content as described above.

  In view of such circumstances, the basic camera work data set for the camera virtually arranged in the three-dimensional space by the three-dimensional CG data is corrected by the correction parameter corresponding to the predetermined viewing condition, and the two-dimensional image is obtained. Has been proposed (see, for example, Patent Document 1). More specifically, an image viewed from a camera virtually arranged in a three-dimensional space of three-dimensional CG data created by a computer is a two-dimensional video displayed on a display, and the basic camera work is corrected. This is a technology that changes 2D video.

According to the technology, after creating 3D CG data as basic data of image content, it is possible to cope with the viewing environment by setting correction parameters corresponding to viewing conditions without changing the 3D CG data. The displayed image content can be displayed. In addition, a user who appreciates the image content can set a correction parameter as appropriate to obtain a moving image according to the user's preference.

  However, the correction parameter is set for each reference camera work data set for each time, and must be set for each of a plurality of viewing conditions. That is, the image producer has to set a plurality of correction parameter groups corresponding to viewing conditions corresponding to the reference camera work data, and there is a problem that the amount of data becomes enormous. In addition, in order for a user to obtain a moving image in accordance with his / her preference, a correction parameter for reference camera work data must be set for each time, and there is a problem that input is troublesome.

  The problem to be solved by the present invention includes the above-described problem as an example.

In addition, it is possible to display a suitable moving image on various image display devices without increasing the data amount. In addition, the viewer can easily change the moving image according to the viewing environment and preference by changing the adjustment coefficient.

  Hereinafter, embodiments of an image processing apparatus, an image processing method, and an image processing program according to the present invention will be described in detail with reference to the drawings.

  As shown in FIG. 1, the image processing apparatus 1 is connected to a content database 2, and the content database 2 is constructed on a large-capacity recording medium such as an HDD or a DVD-ROM. The content database 2 includes a three-dimensional CG data file 3 that stores three-dimensional CG data, a reference camera work data file 4, and a camera work correction data file 5.

  The three-dimensional CG data file 3 stores three-dimensional CG data created by a computer. The reference camera work data file 4 includes the visual field information of the camera set in the virtual three-dimensional space by the three-dimensional CG data, and the visual field information is time series data. In the following embodiment, a plurality of control points are set so that visual field information that changes smoothly in time series with a small amount of data is defined, and a spline curve is set between the set control points. An example of performing interpolation so that each numerical value of the visual field information shows a smooth curvilinear change will be mainly described. That is, the reference camera work data file 4 stores reference camera work data including camera field-of-view information at a plurality of control points set in the virtual three-dimensional space by the three-dimensional CG data. Here, the field-of-view information refers to the camera orientation (x, y, z), the yaw angle (horizontal direction) Y, the pitch angle (vertical direction) P, and the roll angle (around the front-rear axis) R ( Y, P, R). The visual field information appropriately includes a visual field angle W corresponding to the zoom operation of the camera.

As shown in Table 1, the reference camera work data (B) are set for the control points L _{1 to} L _n , respectively.
Reference camera work data (B _m ) = [(x _base , y _base , z _base ) _m , (Y _base , P _base , R _base ) _m , (W _base ) _m ] (m = 1 to n)
Can be shown.

In the above table, times T _{1 to} T _n are the passing times of the respective control points with respect to the reproduction start time, and indicate which control point should be referred to at a certain time T. The visual field information for the intermediate time is obtained by spline interpolation.

The camera work correction data file 5 stores camera work correction data for correcting visual field information at each control point of the reference camera work data. The camera work correction data is set corresponding to the above-described visual field information. That is, as shown in Table 2, the camera work correction data (E) is set corresponding to each control point L _{1 to} L _n ,
Camera work correction data (E _m ) = [(x _eff , y _eff , z _eff ) _m , (Y _eff , P _eff , R _eff ) _m , (W _eff ) _m ] (m = 1 to n)
It is shown in

  The image processing apparatus 1 connected to the content database 2 having the data file as described above includes a reference camera work data input means 6 for inputting the reference camera work data from the reference camera work data file 4 and a camera work correction data file 5. And camera work correction data input means 7 for inputting the camera work correction data from. Further, the image processing apparatus 1 includes an image processing control unit 8, and the image processing control unit 8 is connected to a reference camera work data input unit 6 and a camera work correction data input unit 7. When receiving the reproduction signal from the image reproduction signal input means 9 provided outside the image processing apparatus 1, the image processing control unit 8 reads the visual field information to the reference camera work data input means 6 and the camera work correction data input means 7. Send a signal. The reference camera work data input means 6 that has received the visual field information read signal reads the reference camera work data from the reference camera work data file 4 and inputs the reference camera work data to the image processing apparatus 1. The camera work correction data input means 7 that has received the visual field information read signal reads the camera work correction data from the camera work correction data file 5 and inputs the camera work correction data to the image processing apparatus 1.

  The image processing apparatus 1 includes an adjustment coefficient input unit 10 connected to the image processing control unit 8 and receiving a visual field information reading signal from the image processing control unit 8. Further, the adjustment coefficient input unit 10 is connected to an operation unit 11 outside the image processing apparatus 1. The adjustment coefficient input unit 10 reads the adjustment coefficient (α) for the camera work correction data from the operation unit 11 when receiving the visual field information read signal, and inputs the adjustment coefficient to the image processing apparatus 1. The operation unit 11 is a setting unit that allows an image viewer to arbitrarily set an adjustment coefficient (α). For example, a knob that can continuously change a numerical value such as an adjustment volume or a numeric key that inputs an adjustment coefficient is used. It may be a key switch. The transmission of the visual field information read signal from the image processing control unit 8 to the adjustment coefficient input unit 10 is performed in response to the input of the reproduction signal to the image processing control unit 8 described above.

  The reference camera work data input means 6, the camera work correction data input means 7 and the adjustment coefficient input means 10 are connected to the modified camera work data setting means 12, and each of the reference camera work data, camera work correction data and adjustment coefficient. Is transmitted to the modified camera work data setting means 12. The corrected camera work data setting means 12 is connected to the image processing control unit 8 and receives a camera work data correction signal. The corrected camera work data setting means 12 that has received the camera work data correction signal corrects the reference camera work data based on the camera work correction data adjusted by the adjustment coefficient to obtain the corrected camera work data at each control point. Set. More specifically, the corrected camera work setting unit 12 sets the corrected camera work data (S) by the following equation.

The corrected camera work data (S _m ) includes camera position data (x, y, z) _m , camera orientation data (Y, P, R) _m , and viewing angle data (W) _m. Can be calculated.

  As described in the above equation, the adjustment coefficient (α) is a parameter common to the camera work correction data (E) at a plurality of control points.

Here, the correction of the visual field information performed by the corrected camera work setting unit 12 will be described in detail. In order to simplify the description, the correction of the camera position and the camera direction will be described (the viewing angle W is omitted here). As shown in FIG. 2, the camera positions (x _base , y _base , z _base ) _n to (x _base , y _base , z) are determined by the reference camera work data (B) for the control points L _{n to} L _{n + 2} of the camera C. _base ) _{n + 1} and camera direction (Y _base , P _base , R _base ) _n to (Y _base , P _base , R _base ) _{n + 2} are set for each control point. In addition, the camera position (x _eff , y _eff , z _eff ) _n to (x _eff , y _eff , z _eff ) _{n + 1} and the camera orientation (Y _eff , P _eff , R _eff ) are determined according to the camera work correction data (E). ) _N to (Y _eff , P _eff , R _eff ) _{n + 1} are set for each control point (see Table 3).

  For such reference camera work data (B) and camera work correction data (E), a common adjustment coefficient α is set for the camera work correction data of each control point. Calculated based on

The control points Ls _n , Ls _{n + 1} , and Ls _{n + 2} corrected by the correction camera work setting means have the camera position and the camera orientation from the control points L _n , L _{n + 1} , and L _{n + 2} before correction. fluctuate.

  Here, when the image processing apparatus is described again as shown in FIG. 1, the corrected camera work data (S) set by the corrected camera work setting means 12 is a moving image connected to the corrected camera work setting means 12. It is sent to the image data creation means 13. The moving image data creation means 13 is connected to the image processing control unit 8 and receives a moving image creation signal from the image processing control unit 8. Furthermore, the moving image data creation means 13 is connected to the three-dimensional CG data file 3 of the content database 2. The moving image data creation unit 13 reads the 3D CG data from the 3D CG data file 3 when receiving the moving image creation signal from the image processing control unit 8. The moving image data creating unit 13 creates moving image data using the 3D CG data and the modified camera work data. Specifically, the moving image data creation means 13 applies a B-spline curve to n control points included in the modified camera work data, generates camera work based on continuous visual field information, and further A moving image is sequentially created (rendering process) from the three-dimensional CG data based on the continuous visual field information (see FIG. 2). For example, visual field information is calculated at a time interval of 1/30 seconds, and an image that can be seen from the camera is generated as a still image (moving image data) for each time by rendering processing, and such still images are sequentially displayed. A moving image is generated. The transmission of the moving image creation signal from the image processing control unit 8 to the moving image data creation unit 13 is performed in response to the input of the reproduction signal to the image processing control unit 8 described above.

  The moving image data created by the moving image data creating unit 13 is sent to a moving image data sending unit 14 connected to the moving image data creating unit 13. The moving image data sending means 14 is connected to the display 15 and sends moving image data to the display 15. The display 15 displays the moving image data as a moving image on a display screen (not shown). Since the two-dimensional image of each frame of the moving image is changed by changing the camera work, the impression obtained from the moving image changes.

  In the image processing apparatus 1 having the above-described configuration, the reference camera work data (B) set in advance and the camera work correction data (E) corresponding thereto are arbitrarily set according to the viewing environment and the viewer's preference. A moving image is created from the three-dimensional CG data based on the adjustment coefficient (α). That is, a moving image can be created from three-dimensional CG data without setting camerawork correction data (E) for each viewing environment. As a result, the burden of creating content for the video producer is reduced, and the data capacity of the image data file can be reduced. In addition, by adjusting the adjustment coefficient (α), it is possible to provide an image according to the viewing environment and preferences such as the size of the display screen, so that it has been conventionally performed by a video producer (video provider). The viewer (end user such as an individual) can set the image adjustment arbitrarily and simply.

  The reference camera work data (B) and the camera work correction data (E) as described above are set based on the judgment of the video producer. For example, as shown in FIG. 2, the video producer first sets the reference camerawork data for obtaining a very conservative camerawork (reference camerawork CW1) with little irritation, and until the production by the camerawork seems to be excessive. Information corresponding to the difference between the camera work with enhanced performance effect and the reference camera work CW1 is set as camera work correction data.

  When the movement time between the control points is constant, the linear velocity of the camera passing through the camera path is set according to the length of the camera path formed by connecting the control points. Therefore, the path length of the camera is changed by correcting the control point, and accordingly, the moving speed of the camera is changed. When the moving speed of the camera changes, the dynamic stimulus that the viewer receives from the moving image changes, and the effect of the moving image can be changed.

  Image processing in the image processing apparatus is started when a reproduction signal is input from the image reproduction signal input means 9 to the image processing control unit 8 of the image processing apparatus. As shown in FIG. 3, in the image processing apparatus 1, when a reproduction signal is input to the image processing control unit 8, the image processing control unit 8 transmits a visual field information read signal to the reference camera work data input unit 6. Camera work data (B) is input (S1). Subsequently, in the image processing apparatus 1, the image processing control unit 8 transmits a visual field information read signal to the camera work correction data input means 7, and inputs camera work correction data (E) (S2). Further, in the image processing apparatus 1, the image processing control unit 8 transmits a visual field information read signal to the integer coefficient input unit 10, and the adjustment coefficient for the camera work correction data from the operation unit 11 via the integer coefficient input unit 10. (Α) is input (S3).

  Subsequently, in the image processing apparatus 1, the reference camera work data input means 6, the camera work correction data input means 7 and the adjustment coefficient input means 10 are respectively the reference camera work data (B), the camera work correction data (E) and the adjustment. The coefficient (α) is transmitted to the corrected camera work data setting unit 12, and the image processing control unit 8 transmits a camera work data correction signal to the corrected camera work data setting unit 12. The correction camera work data setting means 12 that has received the camera work data correction signal corrects the reference camera work data (B) based on the camera work correction data (E) adjusted by the adjustment coefficient (α) and performs each control. The corrected camera work data (S) at the point is set (S4). More specifically, the corrected camera work setting unit 12 sets the corrected camera work data (S) by the following equation.

  After the corrected camera work data (S) is set by the corrected camera work setting means 12, the corrected camera work setting means 12 sends the corrected camera work data (S) to the moving image data creation means 13. In addition, the moving image data creation means 13 reads and inputs the 3D CG data from the 3D CG data file 3 when receiving the moving image creation signal from the image processing control unit 8, and the 3D CG. Moving image data is created using the data and the modified camera work data (S5). For example, the moving image data is created by applying a B-spline curve to n control points included in the corrected camera work data to generate camera work based on continuous visual field information, and This is done by sequentially creating (rendering) moving images from the three-dimensional CG data. For example, visual field information is calculated at a time interval of 1/30 seconds, and an image that can be seen from the camera is generated as a still image (moving image data) of one frame for each time by rendering processing.

  Subsequently, the moving image data creating means sends the created moving image data to the moving image data sending means, and the moving image data sending means sends the moving image data as a moving image to the display (S6).

  According to the above-described image processing method, the moving image data can be easily corrected by changing the adjustment coefficient (α). That is, moving image data corresponding to the display environment can be created by changing the adjustment coefficient (α) without depending on the display environment such as the size of the display screen.

  Next, an image processing program capable of causing a computer to perform the image processing method as described above will be described. The program includes an installed computer, a reference camera work data input means for inputting reference camera work data from a reference camera work data file of a content database, and a camera for inputting camera work correction data from a camera work correction data file of a content database. It functions as a work correction data input means and an adjustment coefficient input means for inputting an adjustment coefficient for camera work correction data. Further, the program adjusts the camera work correction data by the adjustment coefficient, corrects the reference camera work data based on the adjusted data, and sets corrected camera work data at each control point. The computer is caused to function as work data setting means. Furthermore, the program includes moving image data creating means for creating moving image data using the 3D CG data read from the 3D CG data file of the content database and the modified camera work data, and the moving image data. The computer is caused to function as moving image data sending means for sending to the display. According to the image processing program that causes the computer to perform the above-described functions, a general-purpose computer such as a personal computer or a small information processing system can be used without using a video creation device used by the video producer and video provider. In the apparatus, a moving image corresponding to the viewing environment of the viewer can be displayed on the display.

  The image processing program can be recorded on a recording medium such as an optical information recording medium such as a DVD-ROM and a magnetic information recording medium such as an HDD. Further, content data applicable to the program may be recorded on the recording medium.

  As a modification, in the above-described embodiment, the connection between the content database 2 and the image processing apparatus 1 may be performed using a network line such as the Internet or wireless or wired communication broadcasting. As another modification, the connection between the image processing apparatus and the display device may be performed using a network line or wireless or wired communication broadcast. According to such a configuration, image data such as three-dimensional CG data that requires a large-capacity recording medium does not need to be held by the viewer, so that it can be used in a small terminal such as a mobile phone, for example. Can watch high-quality moving images.

  As a modification, the adjustment coefficient input means may be means for obtaining an adjustment coefficient corresponding to the screen size of the display from the display as a value specific to the display. For example, as shown in FIG. 4, the adjustment coefficient input means 10 of the image processing apparatus 1 is connected to the display 15, and the other configuration may be substantially the same as the above-described image processing apparatus. The adjustment coefficient input means 10 inputs an adjustment coefficient corresponding to the screen size from the display 15. The input of the coefficient is performed, for example, when the adjustment coefficient input unit 10 receives a visual field information read signal from the image processing control unit 8, and the adjustment coefficient input unit 10 that has received the signal adjusts from the display 15. It is executed in the procedure of receiving the coefficient.

  As another modified example, as shown in FIG. 5, the adjustment coefficient input means 10 is connected to the operation unit 11 and the display unit 15 described above, and the transmission destination of the adjustment coefficient is the operation unit 11 or the display unit 15. It is connected to switching means 16 for switching to either. Other configurations are substantially the same as those in the above-described embodiment. The switching unit 16 is operated by an operator (viewer) of the image processing apparatus 1 and transmits a switching signal including information corresponding to the transmission source of the adjustment coefficient to the adjustment coefficient input unit 10. That is, the switching unit 16 functions as a switch for switching the adjustment coefficient input mode to either the automatic mode (input mode from the display unit 15) or the manual mode (input from the operation unit 11). Note that the switching unit 16 normally transmits a switching signal in which the transmission source of the adjustment coefficient is the display unit 15 in the automatic mode, and after the operator performs an operation of switching from the automatic mode to the manual mode until the release. It is good also as transmitting the switch signal which makes the transmission part of an adjustment coefficient the operation part 11. FIG.

  In the layer processing apparatus having such a configuration, the adjustment coefficient input means 10 determines the source of the adjustment coefficient based on the switching signal input when the visual field information read signal is received from the image processing control unit 8. . If the transmission source of the adjustment coefficient is determined, the adjustment coefficient input means 10 executes the input of the adjustment coefficient from the operation unit 11 or the display unit 15 based on a procedure substantially similar to the adjustment coefficient input procedure described above. .

  As another modification, the adjustment coefficient input unit 10 receives the adjustment coefficient from both the operation unit 11 and the display unit 15, and the adjustment coefficient input from the operation unit 11 and the adjustment input from the display unit 15. The average value of the coefficients may be used as an adjustment coefficient used for correction. According to this method, it is possible to obtain an effect that takes into account both automatic adjustment based on the size of the display and adjustment based on the judgment of the operator.

  As another variation, the visual field information may include the speed and / or acceleration of a camera moving in a three-dimensional space. That is, the camera speed and / or acceleration can be set for each control point, and the moving speed of the camera between the control points can be dynamically changed by the correction coefficient. According to such a configuration, it is possible to provide the viewer with the effect of changing the moving speed of the camera between the control points.

  In the above-described embodiment, reference camera work data (B) and camera work correction data (E) are set for a plurality of control points. As a modification, reference camera work data (B) and camera work correction data (E) may be set according to time. That is, except that the reference camera work data and the camera work correction data are set for each time, other configurations can be made substantially the same as the above-described image processing apparatus, image processing method, and image processing program. Further, even if the reference camera work data and the camera work correction data are set for each time instead of the control point, substantially the same effect as the above-described embodiment can be obtained.

  In the above-described embodiments, the case where the external device connected to the image processing device is a display device is described. However, the external device is a recording device (not shown) including a recording medium for recording moving image data. There may be. That is, the image processing apparatus can be used as a moving image editing apparatus.
