Description

  The present invention relates to image trimming, and more particularly to a technique for trimming an image with reduced user burden.

  In order to leave only a desired portion in the image and delete other unnecessary portions, the image is trimmed. In image trimming, a portion of an image that remains after trimming is called a trimming range. When trimming an image, the trimming range is generally set by the following two methods. In the first method, a start point and an end point are designated by the user on the target image displayed on the display device, and a rectangular shape having a line segment connecting the designated start point and end point as a diagonal line is set as a trimming range. In the second method, a default trimming range is set in advance, and the trimming range set by default is enlarged or reduced, or the position is translated on the target image displayed on the display device. A range is set.

  In the first method, it is possible to set a trimming range having a relatively high degree of freedom. However, with this method, the trimming range cannot be confirmed until the end point is designated. Therefore, for example, when the aspect ratio is limited, it is not possible to set the trimming range so that a desired portion in the target image is included in the trimming range and an unnecessary portion is not included in the trimming range. Have difficulty.

  On the other hand, in the second method, since the trimming range is displayed on the target image displayed on the display device, it can be easily confirmed whether or not a desired portion is included in the trimming range. However, in this method, when the default trimming range does not include a desired portion, it is necessary to enlarge, reduce, or change the position of the trimming range, which places a heavy burden on the user.

  A technique for reducing a user burden in setting a trimming range is disclosed (for example, Patent Document 1). In this technique, a trimming frame indicating a plurality of trimming range candidates having different sizes is displayed on a target image, and a trimming range corresponding to the trimming frame selected by the user is set.

A. Example:
B. Variations:

A. Example:
FIG. 1 is an explanatory diagram schematically showing a configuration of an image processing apparatus as an embodiment of the present invention. The image processing apparatus 100 according to the embodiment is configured as a computer. The image processing apparatus 100 includes a CPU 110, a display unit 120 such as a liquid crystal monitor, an operation unit 130 such as a keyboard and a mouse, an interface unit (I / F unit) 140, an internal storage device 200 such as a ROM and a RAM, It has. These components of the image processing apparatus 100 are connected to each other via a bus 150. Note that the image processing apparatus 100 may include an external storage device such as a hard disk drive.

  The interface unit 140 includes a plurality of input / output terminals, and exchanges information with an external device. For example, the interface unit 140 is connected to the printer 300 via a cable and supplies print data to the printer 300. The interface unit 140 is connected to a digital still camera (not shown) via a cable, and reads image data. The interface unit 140 may read image data via an external storage medium or a network. The read image data is stored in the internal storage device 200 or an external storage device (not shown).

  The internal storage device 200 stores an image processing unit 210, a display processing unit 220, and a print processing unit 230. The image processing unit 210 is a computer program that executes image trimming processing under a predetermined operating system. The display processing unit 220 is a display driver that controls the display unit 120. The print processing unit 230 is a printer driver that controls the printer 300. The CPU 110 reads and executes these programs from the internal storage device 200, thereby executing image trimming / output processing described later.

  The image processing unit 210 includes a feature portion detection unit 212, a candidate setting unit 213, a selection instruction receiving unit 214, an adjustment unit 215, and a trimming processing unit 216. The functions of these units will be described in detail in the description of image trimming / output processing described later.

  FIG. 2 is a flowchart showing a flow of image trimming / output processing by the image processing apparatus 100. The image trimming / output process is a process of performing trimming of a target image to be processed and printing the trimmed target image (hereinafter referred to as “trimmed image TI”) using the printer 300.

  In step S110, the image processing unit 210 (FIG. 1) sets the target image OI. The target image OI is an image to be subjected to image trimming / output processing. Of the images represented by the image data stored in the internal storage device 200 or an external storage device (not shown), an image selected by the user is set as the target image OI. For example, the user selects one of the images displayed on the display unit 120 by operating the operation unit 130. FIG. 3 is an explanatory diagram illustrating an example of the set target image OI.

  In step S120 (FIG. 2), the image processing unit 210 (FIG. 1) sets an output size when the trimmed image TI is printed by the printer 300. The image processing unit 210 sets the output size based on an instruction from the user via the operation unit 130. Note that the image processing unit 210 may set the output size based on the output size acquired from the printer 300.

  In step S130 (FIG. 2), the feature portion detector 212 (FIG. 1) detects a feature portion in the target image OI. The feature part detection unit 212 of the present embodiment detects at least one of the following three parts as a feature part. The first part is a part representing a human face, the second part is a part in focus, and the third part is a part representing at least one of a horizontal line and a vertical line.

  The part representing the human face in the target image OI can be detected using a known face detection technique. Known face detection techniques include face detection by pattern matching using an average face or the like, face detection by skin color region extraction, face detection by SVM (Support Vector Machine) discrimination method using frequency characteristics of face organs, and the like. Note that the feature portion detection unit 212 may detect a portion representing the whole human body in the target image OI. Whole body detection can be performed by a pattern matching method, estimation from a detection result of a portion representing a human face, contour detection using the estimation, or the like.

  The in-focus portion of the target image OI can be detected by extracting a portion where pixels with sharp edges are solidified from the target image OI. That is, a passive method used in general autofocus technology may be applied. Note that when the image file including the image data of the target image OI includes information representing the focus position, the information may be used to detect a focused portion in the target image OI.

  The detection of the portion representing at least one of the horizontal line and the vertical line in the target image OI can be performed using, for example, an edge detection operator that reacts only to the horizontal component or the vertical component. In the present embodiment, the detected horizontal line and vertical line divide at least one of the luminance component and the color difference component of the target image OI into two. Further, the horizontal line and the vertical line to be detected are not necessarily a straight line, and may be a substantially straight line. Moreover, it is preferable that the edge detection operator is not a pixel unit operator but a global operator.

  FIG. 4 is an explanatory diagram illustrating an example of the detection result of the characteristic portion in the target image OI. In the example of FIG. 4, a part representing a human face (hereinafter referred to as “face area FA”) and a horizontal line HL are detected.

  In step S140 (FIG. 2), the candidate setting unit 213 (FIG. 1) sets a trimming range candidate based on the position of the feature portion detected in step S130 in the target image OI. Here, the trimming range means a portion of an image that remains after trimming in the target image OI. In this embodiment, the trimming range candidates are set to have the same aspect ratio as the output size aspect ratio set in step S120.

  FIG. 5 is an explanatory diagram illustrating a first example of a trimming range candidate setting method. In the example of FIG. 5, a whole body area BA representing the whole body is estimated from the detected face area FA, and a range including the whole body area BA is set as a trimming range candidate. Note that the outer periphery of the trimming range is referred to as a trimming frame TF. In this way, candidates for the trimming range can be set so that the trimmed image TI is an image representing the whole human body. FIG. 5A shows a trimming frame TF that is a set trimming range candidate. FIG. 5B shows a trimmed image TI corresponding to the set trimming range candidate. In the example of FIG. 5, the trimming range candidates are set as a vertically long (portrait shape) range, but may be set as a horizontally long range. The whole body area BA is preferably estimated as an area having a size 7 to 9 times larger than the face area FA.

  FIG. 6 is an explanatory diagram illustrating a second example of a trimming range candidate setting method. In the example of FIG. 6, the trimming range candidates are set so that the detected face area FA is positioned at the golden division point of the trimming range. That is, the trimming range candidates are set so that the face area FA is positioned on a straight line that divides at least one of the width and height of the trimming range into 1: 0.618. In this way, the trimming range candidates can be set so that the trimmed image TI has an image with a preferable composition. FIG. 6A shows a trimming frame TF that is a set trimming range candidate. FIGS. 6B and 6C show trimmed images TI corresponding to the set trimming range candidates.

  In the example of FIG. 6, the trimming range candidates are set so that the face area FA is positioned on a straight line that divides the height of the trimming range into 1: 0.618 from the bottom to the top. However, on the contrary, the trimming range candidates may be set so that the face area FA is located on a straight line that divides the height of the trimming range from 1: up to 1: 0.618. .

  The size of the trimming range candidate in the example of FIG. 6 may be set based on the size of the face area FA. That is, at least one of the width and height of the trimming range candidate may be set to a predetermined multiple of at least one of the width and height of the face area FA. The size of the trimming range candidate may be set using a user-specified value or a default value. The size of the trimming range candidate may be set in consideration of the image quality of the print image. For example, from the output size (for example, L size), a preferred number of pixels (for example, about 2 million pixels) of image data in order to ensure sufficient image quality when printing an image at the output size is set, and a trimming range candidate is set. May be set to be in a range including the number of pixels. In the example of FIG. 6, the trimming range candidate is set as a horizontally long range, but may be set as a vertically long range.

  FIG. 7 is an explanatory diagram illustrating a third example of a trimming range candidate setting method. In the example of FIG. 7, the trimming range candidates are set so that the horizontal line HL is positioned on a straight line that divides the height of the trimming range into three. In this way, the trimming range candidates can be set so that the trimmed image TI has an image with a stable feeling. FIG. 7A shows a trimming frame TF that is a set trimming range candidate. FIG. 7B shows a trimmed image TI corresponding to the set trimming range candidate. In the example of FIG. 7, the position along the width direction of the trimming range candidate in the target image OI is set so that the face area FA is positioned at the center of the trimming range in the width direction.

  In the example of FIG. 7, the trimming range candidates are set so that the horizontal line HL is positioned on a straight line that divides the height of the trimming range 2: 1 from below to above. Conversely, the trimming range candidates may be set such that the horizontal line HL is positioned on a straight line that divides the height of the trimming range from 2 to 2 along the top.

  The size of the trimming range candidate in the example of FIG. 7 may also be set based on the size of the face area FA as in the example of FIG. 6 described above, or may be set using a user-specified value or default value. Alternatively, it may be set in consideration of the image quality of the print image. In the example of FIG. 7, the trimming range candidate is set as a horizontally long range, but may be set as a vertically long range.

  The trimming range candidate setting method is not limited to the method described with reference to FIGS. 5 to 7, and any trimming range candidate may be set based on the position of the characteristic portion in the target image OI. Other setting methods can also be adopted. For example, a range including a human face to the chest may be estimated based on the face area FA, and the range may be set as a trimming range candidate. In addition, when a vertical line is detected, the trimming range candidate may be set so that the vertical line is positioned on a line that divides the width of the trimming range into three. If a plurality of face areas FA are detected, a range including all the whole body areas BA corresponding to the plurality of face areas FA may be set as a trimming range candidate. In addition, the trimming range candidates may be set so that the face area FA or the whole body area BA is located at the center of at least one of the width and height of the trimming range. In addition, when a focused position in the target image OI is detected, a trimming range candidate may be set so that the focused position is located at the golden division point of the trimming range. Further, the trimming range candidate may be set so that the in-focus position is located at the center of at least one of the width and height of the trimming range.

  The candidate setting unit 213 (FIG. 1) sets a preset number of trimming range candidates using the above-described method. The candidate setting unit 213 may set the maximum number of trimming range candidates that can be set. In step S130, if the feature portion detection unit 212 (FIG. 1) fails to detect a feature portion, the candidate setting unit 213 may set the default trimming range as a trimming range candidate.

  In step S150 (FIG. 2), the image processing unit 210 (FIG. 1) controls the display processing unit 220 to display the set trimming range candidates on the display unit 120. FIG. 8 is an explanatory diagram illustrating an example of display of trimming range candidates on the display unit 120. The display unit 120 includes a target image display area 122, a trimming range candidate display area 124, and an operation button display area 126. The target image display area 122 displays the target image OI. In the trimming range candidate display area 124, an image corresponding to a trimming range candidate in the target image OI is displayed. That is, the trimming image TI generated when trimming is performed according to the trimming range candidates is displayed in the trimming range candidate display area 124. When a plurality of candidates are set in step S140 (FIG. 2), a plurality of images corresponding to a plurality of trimming range candidates in the target image OI are arranged at different positions in the trimming range candidate display area 124 at the same time. Is displayed. In the trimming range candidate display area 124, all the set candidates may be displayed simultaneously, or all candidates may be displayed by scrolling the screen.

  In step S160 (FIG. 2), the selection instruction receiving unit 214 (FIG. 1) receives a selection instruction for selecting one of the trimming range candidates by the user. The selection instruction is performed when the user operates the operation unit 130 (FIG. 1) to select one of the most preferable candidates from the trimming range candidates displayed in the trimming range candidate display area 124. FIG. 8A shows the state of the display unit 120 when the trimming range candidate displayed at the top of the trimming range candidate display area 124 is selected. As shown in FIG. 8A, when a trimming range candidate is selected, a trimming frame TF corresponding to the selected candidate is displayed on the target image OI displayed in the target image display area 122. Further, as shown in FIG. 8B, when the selection is changed to another trimming range candidate (second candidate from the top in the example of FIG. 8B), it is displayed on the target image OI. The trimming frame TF is changed to one corresponding to the selected candidate. The hatching in FIG. 8 is shown for the sake of convenience in order to indicate that the trimming range candidate with the hatching is selected, and is displayed on the actual display unit 120. It is not.

  In step S170 (FIG. 2), the adjustment unit 215 (FIG. 1) performs fine adjustment of the selected trimming range candidate. The fine adjustment of the trimming range candidate means that the trimming range candidate is enlarged / reduced or translated. Fine adjustment of the trimming range candidates is performed by the user operating the operation unit 130 (FIG. 1) and selecting the enlargement / reduction button 127 or the move button 128 displayed in the operation button display area 126. When the enlargement / reduction button 127 or the move button 128 is selected, the display of the selected trimming range candidate displayed in the trimming range candidate display area 124 is changed accordingly. In addition, the trimming frame TF displayed in the target image display area 122 is also changed. While confirming the display of the trimming range candidate display area 124 and the target image display area 122, the user performs fine adjustment of the trimming range candidates so that the trimming range becomes a desired range. If fine adjustment is not necessary, step S170 is skipped.

  In step S180 (FIG. 2), the image processing unit 210 (FIG. 1) receives a print instruction. The print instruction is performed by the user operating the operation unit 130 (FIG. 1). In step S190 (FIG. 2), the image processing unit 210 (FIG. 1) controls the print processing unit 230 to perform the printing process of the trimmed image TI according to the trimming range candidates after the fine adjustment in step S170. As a result of the printing process, the trimmed image TI is printed by the printer 300.

  As described above, in the image processing apparatus 100 according to the present embodiment, a trimming range candidate assumed to be desired by the user is set based on the detected position of the feature portion in the target image OI. The user can obtain the trimmed image TI by simply selecting one of the trimming range candidates displayed on the display unit 120 and performing simple fine adjustment as necessary, and can print the trimmed image TI. Can do. Therefore, in the image processing apparatus 100 of the present embodiment, it is possible to reduce the burden on the user when performing image trimming.

  Further, in the image processing apparatus 100 of the present embodiment, as shown in FIG. 8, the image corresponding to the set trimming range candidate is different from the position where the target image OI is displayed (target image display area 122). It is displayed at the position (trimming range candidate display area 124). Therefore, for example, the trimming image TI as the trimming result can be easily confirmed and grasped as compared with the method of displaying the trimming range candidates by displaying the trimming frame TF on the target image OI. Further, when one of the displayed trimming range candidates is selected, the position of the trimming frame TF in the target image OI is displayed in the target image display area 122, so that the trimming range in the target image OI can be easily confirmed and grasped. be able to.

  Further, in the image processing apparatus 100 of the present embodiment, as shown in FIG. 8, when a plurality of trimming range candidates are set, a plurality of images corresponding to a plurality of trimming range candidates in the target image OI are trimmed. They are displayed side by side at different positions in the range candidate display area 124. Therefore, for example, a plurality of trimming range candidates can be easily compared with a method of displaying a plurality of trimming range candidates by displaying a plurality of trimming frames TF on the target image OI.

  Further, in the image processing apparatus 100 of the present embodiment, fine adjustment of the set trimming range candidates can be performed. Therefore, it is possible to easily set the trimming range according to the user's desire.
