Description

  The present invention relates to an image processing content determination device, an image processing content determination program, and an image processing content determination method. More specifically, the present invention relates to an apparatus, a program, and a method for determining a processing content including a processing method and a processing amount when processing discretized image information.

  Since a raster image itself is a set of pixels that do not include information on the arrangement, it requires more calculation processing than vector data to edit it. Particularly in recent years, the color depth, gradation range, and the like of raster images have increased, and the amount of data processing for reflecting editing results on image data has increased. Therefore, if the image is changed in real time on the screen according to the user's operation, the response of the screen may be delayed and the operability may be lowered. For this reason, in many image editing means, the processing method and the processing amount are designated in advance by numerical values or the like, and the processing for the entire image is executed collectively.

  On the other hand, for example, an image photographed with a digital camera or the like is accompanied by various distortions that inevitably occur in the optical system during photographing. For this reason, even general users who are not skilled in using image processing software, image processing apparatuses, and the like often perform image editing to correct image distortion. However, it is extremely difficult for a low-level user to obtain a desired editing result by an editing operation involving indirect designation by numerical values or the like.

Therefore, Patent Document 1 below proposes that grid information is embedded in image information and used as a reference for editing history. Thus, a technique is disclosed that makes it easy to trace back the editing history and return to the state before editing. Also, even if editing fails, the prototype is secured and trial and error is allowed, so that it is easy for a low-level user to edit an image.
JP 2004-310585 A

  However, in Patent Document 1, the grid is also deformed by the same deformation as the image is deformed with reference to the orthogonal grid. That is, the orthogonal grid corresponds to the image before editing, and the deformed grid corresponds to the image after editing. Therefore, when there is distortion of the optical system in the image before editing and the distortion is corrected, in Patent Document 1, an appropriate deformation method for removing the distortion and the deformation amount of the image after editing are predicted. An instruction is input to the image processing apparatus. Therefore, for example, in order to remove the distortion from the image and correct it, there is a problem that there is trial and error or skill in the deformation amount.

  Therefore, as a first aspect of the present invention, a reference graphic generation unit that generates a reference graphic, a modified graphic display unit that displays a deformed graphic obtained by deforming the reference graphic in accordance with a deformation instruction received from the outside, superimposed on the input image, and An image processing content determination device provided with a processing content calculation unit that calculates the content of conversion processing for converting the deformed graphic displayed at that time into a reference graphic in response to a determination instruction received from outside Is done. Accordingly, various processing methods can be appropriately selected and executed with an appropriate processing amount. Therefore, for example, an image correction apparatus that can easily and reliably correct image distortion can be formed.

  According to one embodiment, in the image processing content determination device, the deformed graphic display unit accepts a deformation instruction input via a pointing device to at least one of the displayed deformed graphic and reference graphic. Also good. Thereby, while being able to determine the processing content easily, a processing content can be adjusted in consideration of a user's instruction.

  According to another embodiment, the image processing content determination apparatus further includes a correlation instruction receiving unit that receives a correlation instruction related to the relative relationship between the reference graphic and the input image from the outside, and the reference graphic generation unit includes: A reference graphic may be generated based on the received correlation instruction. Thereby, the processing content can be determined by an intuitive operation.

  According to another embodiment, the processing content calculation unit may calculate the processing amount in the conversion process and determine the processing content based on the calculated processing amount. As a result, it is possible to easily and reliably determine an appropriate processing amount while learning knowledge about the operation.

  According to another embodiment, the deformed graphic display unit may display a deformed graphic obtained by deforming the reference graphic in an equivalent manner to the case where distortion, keystone distortion, or tilt occurs in the input image in accordance with the deformation instruction. As a result, an image correction apparatus that can easily and reliably correct various distortions such as distortion, keystone distortion, and tilt can be formed.

  According to another embodiment, the reference graphic may include a vertical line and a horizontal line. This makes it easier to match the deformed figure to the element of the image to be processed, and the operation becomes easier.

  According to another embodiment, the deformed graphic display unit may display a deformed graphic obtained by deforming the reference graphic so as to be along one of the lines included in the input image that should be horizontal or vertical. . Thereby, the procedure concerning determination of the processing content can be reduced. Further, it is possible to assist a user operation by suggesting an operation to be executed next.

  According to another embodiment, the image processing apparatus may further include a processing image generation unit that converts the input image according to the processing content calculated by the processing content calculation unit and generates a processing image. As a result, the user can obtain an image on which desirable processing has been performed.

  Furthermore, as a second embodiment of the present invention, a reference graphic generation procedure for generating a reference graphic, and a modified graphic display procedure for superimposing and displaying a deformed graphic obtained by deforming the reference graphic in accordance with a deformation instruction received from the outside on the input image, Image processing for causing the information processing apparatus to execute a processing content calculation procedure for calculating the content of conversion processing for converting the deformed graphic displayed at that time into a reference graphic in response to a determination instruction received from the outside A content determination program is provided. As a result, the above-described effects can be enjoyed using a general-purpose information processing apparatus or the like as well as a dedicated machine.

  Still further, as a third aspect of the present invention, a reference graphic generation step for generating a reference graphic, and a modified graphic display step for superimposing and displaying a deformed graphic obtained by deforming the reference graphic in accordance with a deformation instruction received from the outside on the input image. And a processing content calculation step for calculating the content of the conversion processing for converting the deformed graphic displayed at that time into a reference graphic in response to a determination instruction received from the outside. Provided. Thereby, the above effects can be enjoyed regardless of hardware resources.

  Hereinafter, the present invention will be described through embodiments of the invention. However, the following embodiments do not limit the invention according to the claims. In addition, not all the combinations of features described in the embodiments are essential for the solving means of the invention.

  FIG. 1 is a diagram schematically illustrating the structure of an image correction apparatus 100 as an embodiment of an image processing content determination apparatus. As shown in the figure, the image correction apparatus 100 executes a storage unit 120 that stores an image rasterized by a digital camera 112, a scanner 114, or the like as input image information 122, and information processing at each processing stage described later. A reference graphic generation unit 130, a deformed graphic generation unit 140, a correspondence calculation unit 150, a conversion amount calculation unit 160, and a corrected image generation unit 170.

  When receiving a correction processing start instruction from the user via an input device such as the keyboard 116 and the pointing device 118, the reference graphic generation unit 130 reads the input image information 122 from the storage unit 120, while serving as a reference for the correction processing. Graphic information 132 is generated and held. Further, the reference graphic generation unit 130 superimposes the input image information 122 and the reference graphic information 132 and causes the display device 180 to display an image in which both are combined.

  When the deformed graphic generation unit 140 receives a deformation instruction from the user via the input device such as the keyboard 116 and the pointing device 118, the deformed graphic generation unit 140 performs a deformation process on the reference graphic information 132 generated by the reference graphic generation unit 130. Executed to generate deformed graphic information 142. The deformed graphic generation unit 140 also has a function as a deformed graphic display unit that superimposes the deformed graphic information 142 on the input image information 122 and displays it on the display device 180 instead of the reference graphic information 132. The deformed figure generation unit 140 stores a conversion formula for deforming the reference image into a deformed image in association with the type of the deformation method, and based on the designation of the type of deformation method and the input of the deformation amount from the user A deformed image is generated based on the conversion formula. Here, “type of deformation method” refers to deformation processing for correcting distortion aberrations such as barrel distortion and pincushion distortion, deformation processing for correcting keystone distortion caused by tilt shooting, and tilt of the camera. For example, rotation processing for correcting the tilt of the generated image.

  When the correspondence calculation unit 150 receives an instruction from the user via the input device such as the keyboard 116 and the pointing device 118 that the amount of deformation in the deformation process has been determined, the deformation displayed on the display device 180 at that time. The graphic information is stored as the fixed graphic information 144. Further, the correspondence between the fixed graphic information 144 and the input image information 122 is calculated. Thereby, the fixed figure information 144 and the input image information 122 are associated. In addition, the conversion amount calculation unit 160 refers to the confirmed graphic information 144 and calculates conversion amount information 162 necessary for processing for converting the confirmed graphic information 144 into the reference graphic information 132.

  The corrected image generation unit 170 refers to the correspondence information 152 and the conversion amount information 162 and executes a conversion process equivalent to the conversion process for returning the confirmed graphic information 144 to the reference graphic information 132 for the input image information 122. . As a result, corrected image information 172 is generated from the input image information 122. Further, the corrected image generation unit 170 displays the corrected image information 172 on the display device 180 as an image.

  FIG. 2 is a flowchart F100 showing a processing procedure in a program executed by the image correction apparatus 100 as described above. As shown in the figure, the reference graphic generation unit 130 of the image correction apparatus 100 waits for an instruction to start correction processing (S101). When the input of the instruction is received (S101: Yes), the reference graphic generation unit 130 generates a reference graphic (S102), and the reference graphic is superimposed on the input image and displayed on the display device 180 (S103). The instruction for starting the correction process includes the type of deformation method suitable for the correction process.

  Next, the deformed figure generation unit 140 waits for the designation of a deformation amount, which is a parameter value in the designated deformation method (S104). Upon receiving an instruction to specify the deformation amount (S104: Yes), the deformed graphic generation unit 140 generates a deformed graphic obtained by deforming the reference graphic according to the input deformation amount (S105). Further, the deformed figure generation unit 140 replaces the generated deformed figure with a reference figure and superimposes it on the input image and displays it on the display device 180 (S106).

  Therefore, the user who instructed the deformation amount in S105 can visually recognize the deformation amount in Step S106. Further, by displaying the deformed figure corresponding to the deformation amount superimposed on the input image, the user can easily grasp the deformation amount necessary for proper correction. The series of processing from step S104 to step S105 is repeated until an instruction to determine the deformation amount is input to the correspondence calculation unit 150 (S107: No).

  That is, when an instruction to determine the deformation amount is input in step S107 (S107: Yes), the correspondence calculation unit 150 takes in the deformed figure displayed at that time as a confirmed deformed figure, and confirms the confirmed deformed figure. And the input image are calculated (S108). Note that the “correspondence” in the present embodiment includes information indicating the relative position between each pixel of the input image formed as a set of pixels and the determined deformed figure.

  Furthermore, the conversion amount calculation unit 160 calculates a conversion amount necessary for executing the conversion process for returning the deformed graphic to the original reference graphic based on the fixed graphic information (S109). The conversion amount may be newly calculated with reference to the original reference graphic and the confirmed deformed graphic, or may be calculated from the instruction stored in the deformed graphic generation unit 140 in step S104. May be.

  Subsequently, the modified image generation unit 170 refers to the correspondence calculated in step S108 and the conversion amount calculated in step S109, and performs a deformation process equivalent to the process of converting the deformed graphic into the reference graphic. Run on the input image. Thereby, the corrected image generation unit 170 generates a corrected image (S110). Further, the corrected image generation unit 170 displays the generated corrected image on the display device 180 (S111).

  As is clear from the above description, in the series of processing procedures described above, the processing contents including the image processing method and the processing amount are determined by steps S102, S104, S105, S106, S107, S108, and S109. The deformed graphic corresponds to the input image before correction, and the reference graphic corresponds to the corrected image after correction. Therefore, the user corrects the distortion by inputting the amount of deformation while viewing the deformed figure on the screen of the display device 180, and deforming the deformed figure on the screen to match the distortion included in the input image. The corrected image can be easily obtained.

  FIG. 3 is a diagram illustrating an example of the display screen 10 that the reference graphic generation unit 130 displays on the screen 300 of the display device 180 in step S103 of the flowchart F100. In the figure, an input image 310 and a reference graphic 400 are displayed on a screen 300 so as to overlap each other.

  Note that the input image 310 displayed in this drawing includes so-called pincushion distortion. The reference graphic 400 is a grid graphic including a plurality of horizontal lines 402 and vertical lines 404, respectively. Furthermore, the reference graphic 400 includes a rectangular guide graphic 409, a handle 408 disposed at the center of each side of the guide graphic 409, and a black circle-shaped handle 406 disposed at the center.

  The handles 406 and 408 can be moved on the screen 300 by a drag operation by the pointing device 118, for example. As a result, the deformation figure generation unit 140 can be instructed to change the deformation amount, and the reference figure 400 can be transformed into the deformation figure 410 on the screen 300. The “drag operation” means an operation of moving the pointer while operating a switch provided on the pointing device 118 itself or a modifier key of the keyboard 116.

  FIG. 4 is a diagram showing the display screen 20 displayed on the screen 300 of the display device 180 in the operations of steps S104 to S107 executed while referring to the display image. Note that the same components as those in FIG. 3 are denoted by the same reference numerals, and redundant description is omitted.

  As shown in the figure, here, a deformed figure 410 generated by the deformed figure generating unit 140 is displayed instead of the reference figure 400. The guide graphic 409 is also deformed according to the deformed graphic 410. At this time, each curve forming the deformed figure 410 and the guide figure 409 is the same curve as the distortion generated in the image due to the distortion aberration of the optical system of the photographing machine.

  Such a deformation is a result of the user operating the handle 408 via the pointing device 118 and moving the handle 408 toward the center of the screen 300. At this time, the user can input an instruction for the amount of deformation of the deformed figure 410 according to the amount of movement of the handle 408. Further, the user can modify the horizontal line or the vertical line forming the deformed figure 410 and the guide figure 409 so as to follow the figure that can be determined as the horizontal line or the vertical line included in the input image, so that it is suitable for correcting pincushion distortion. The amount of deformation can be indicated.

  In FIG. 4, the input image 310 on the screen 300 is displayed without being deformed until an input of a determination instruction is received from the user. Therefore, even when the data amount of the input image 310 is large, the reference graphic 400 having a much smaller data amount than the input image 310 is deformed into the deformed graphic 410 with respect to the input of the deformation amount from the user. Therefore, compared with the case where the input image 310 itself is corrected and displayed in real time according to the deformation amount, the response on the screen 300 is quicker and it is possible to prevent the operability for the user from being lowered.

  FIG. 5 is a diagram showing the display screen 30 that the corrected image generation unit 170 displays on the screen 300 of the display device 180 in step S111 described above. As shown in the figure, a correction image 330 from which the pincushion distortion is removed is displayed here.

  Therefore, as described above, the deformed graphic 410 corresponds to the input image 310 before correction, and the reference graphic 400 corresponds to the corrected image 330 after correction. Therefore, the user inputs the deformation amount while viewing the deformed graphic 410 on the screen 300 of the display device 180, and deforms the deformed graphic 410 on the screen 300 so as to match the distortion included in the input image 310. Accordingly, it is possible to easily obtain the corrected image 330 in which the distortion is corrected.

  Note that, for example, when the input image 320 includes barrel distortion caused by distortion, such as the input image 320 displayed on the display screen 40 shown in FIG. The deformed figure 420 can be made to follow the input image 320 by moving outward. In this way, barrel distortion can be accurately corrected by the same procedure.

  Although illustration of the operation is omitted, the black circular handle 406 displayed in the center of the reference graphic 400 and the deformed graphic 410 moves the entire reference graphic 400 or the entire deformed graphic 410 by operating this. be able to. Thereby, the center position used as the reference | standard of a deformation | transformation process can be changed.

  Furthermore, although the reference graphic 400 is displayed together with the corrected image 330 in FIG. 5, the reference graphic 400 may not be displayed at this stage.

  Furthermore, the deformation process of the deformed figures 410 and 420 by the deformed figure generating unit 140 in step S106 can be automated to some extent. That is, in some cases, a horizontal line or a vertical line included in the input image 310 can be estimated from a large line segment included in the image. In this case, the reference graphic 400 is automatically set to the deformed graphic 410 in accordance therewith. it can. However, it is preferable that a horizontal line or a vertical line in the input image 310 that is automatically extracted can be changed to another line segment based on a user input. In addition, even if the generation of the deformed figure is not automated, the horizontal line 402 or the vertical line 404 forming the reference figure 400 is displayed along the large line segment extracted from the input figure, so that the user's next operation can be performed. It can also be made easier. When displaying the deformed figure 410 from the beginning, the display of the reference figure (S103) in FIG. 2 can be omitted.

  FIG. 7 is a diagram showing the display screen 50 displayed on the screen 300 by superimposing the other input image 340 and the reference graphic 400. As shown in the figure, the input image 340 is inclined. Therefore, in order to correct the input image 340, a correction process for rotating the image is executed.

  As shown in the figure, the reference graphic 400 is superimposed on the input image 340 displayed on the screen 300. However, the deformation process, that is, the rotation process performed here is different from the correction process for distortion aberration for the input image 310 shown in FIGS. 3 and 6. Therefore, the shape of the guide graphic 403 included in the reference graphic 400 displayed here and the arrangement of the handles 408 are different from those in FIG. Thereby, the user can intuitively confirm that the type of the deformation process designated by the user is the rotation process.

  FIG. 8 shows a display screen 60 corresponding to the processing executed in the deformed figure generation unit 140, the correspondence calculation unit 150, and the conversion amount calculation unit 160 in steps S104 to S107 with respect to the input image 340 shown in FIG. FIG. Note that the same components as those in FIG. 8 are denoted by the same reference numerals, and redundant description is omitted.

  As shown in the figure, the deformed figure 430 displayed by the deformed figure generating unit 140 by operating the handle 408 includes a horizontal line 402 or a vertical line 404 included in the reference graphic 400, and a horizontal line or vertical line included in the input image 340. It is rotated around the handle 406 so as to be parallel to the vertical line. Therefore, in step S <b> 110, the corrected image generation unit 170 performs a deformation process equivalent to the process of returning the deformed graphic 430 to the reference graphic 400 on the input image 340. In this way, in step S111, the corrected image generation unit 170 causes the display device 180 to display the corrected image 330 that is erected similarly to the display screen 30 shown in FIG.

  FIG. 9 is a diagram showing the display screen 70 displayed on the display device 180 by the reference graphic generation unit 130 superimposing the reference graphic 400 on another input image 350. As shown in the figure, this input image 350 includes so-called keystone distortion (trapezoid distortion). Therefore, the deformation process executed by the correction image generation unit 170 to correct the input image 350 is different from the correction process for the input images 310, 320, and 340 shown in FIGS. Different. Therefore, even in the reference graphic 400 displayed by the reference graphic generation unit 130, the shape of the guide graphic 405 included therein and the arrangement of the handles 408 are unique.

  FIG. 10 is a diagram showing a display screen 80 that the deformed graphic generation unit 140 displays on the display device 180 in steps S104 to S107 with respect to the input image 350 shown in FIG. Note that the same components as those in FIG. 9 are denoted by the same reference numerals, and redundant description is omitted.

  As shown in the figure, here, a trapezoidal deformed figure 440 that is deformed so that the lower part of the reference figure 400 expands according to the trapezoidal distortion of the input image 350 is displayed. Also in this case, the transformation amount calculation unit 160 appropriately determines the transformation amount in step S107 after deforming the transformation graphic 440 so that the horizontal line and the vertical line included in the transformation graphic 440 are along the input image 350. To obtain an appropriate amount of deformation. Accordingly, the corrected image generation unit 170 can display the corrected image 330 corrected for keystone distortion on the display device 180 in step S111.

  Note that the trapezoidal distortion of the input image 350 may occur asymmetrically, for example, on the left or right or top and bottom of the image. Therefore, it is preferable that the deformed graphic generation unit 140 can generate the non-target deformed graphic 440 left and right and up and down when each handle 408 is individually operated.

  FIG. 11 is a diagram schematically illustrating another structure of the image correction apparatus 200 that can perform the correction process. The same components as those in the image correction apparatus 100 shown in FIG. 1 are denoted by the same reference numerals, and redundant description is omitted.

  As shown in the figure, in the image correction apparatus 200, the correspondence calculation unit 250 is arranged between the reference graphic generation unit 130 and the deformed graphic generation unit 140, so that the image correction shown in FIG. Different from the device 100. The correspondence relationship information 252 calculated by the correspondence relationship calculation unit 250 in the image correction apparatus 200 is information indicating the correspondence relationship between the input image information 122 and the reference graphic information 132, and the image shown in FIG. Different from the correction device 100.

  However, also in this image correction apparatus 200, the corrected image generation unit 170 can generate the corrected image information 172 from the input image information 122 with reference to the correspondence relationship information 252 and the conversion amount information 262. Further, the operation on the user side for this series of processing is not different from the case of the image correction apparatus 100 shown in FIG. Also in this image correction apparatus 200, the deformed graphic generation unit 140 also has a function as a deformed graphic display unit, and the reference graphic generation unit 130, the modified graphic generation unit 140, and the conversion amount calculation unit 260 determine the image processing content. It is an example of an apparatus.

  FIG. 12 is a flowchart F200 showing a procedure of correction processing in the image correction apparatus 200 shown in FIG. In the figure, steps S201 to S203, S205 to S208, and S209 to S211 are the same as S101 to S103, S104 to S107, and S109 to S111 in the flowchart F100 shown in FIG. It is substantially the same. However, the difference is that, after step S203 in which the reference graphic generation unit 130 displays the input image and the reference graphic, the correspondence calculation unit 250 executes step S204 in which the correspondence information 252 is calculated. As described above, there is no change in the operation on the user side even in this procedure. However, in this procedure, processing with a large processing load such as correspondence calculation and conversion amount calculation can be distributed in different steps. In the above-described series of processing procedures, the image processing contents including the image processing method and the processing amount are determined in steps S202, S205, S206, S207, S208, and S209.

  As described above, according to the present embodiment, since the deformed figure obtained by deforming the reference graphic is matched with the input image displayed including distortion or the like, it is not necessary to deform the reference graphic while predicting the deformation amount of the input image. Well, it is possible to reliably correct image distortion by a simple operation. Further, the present invention is not limited to processing for correcting image distortion, but can be applied to various image processing including processing such as movement, rotation, and deformation.

  Furthermore, although the present invention has been described using the embodiment, the technical scope of the present invention is not limited to the scope described in the embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be added to the above-described embodiment. Further, it is apparent from the description of the scope of claims that embodiments with such changes or improvements can also be included in the technical scope of the present invention.
