  The present invention has been made in view of the above circumstances, and is an image placement apparatus capable of automatically placing a plurality of electronic images such as electrophotographic images in a specific area efficiently with simple arithmetic processing. And to provide a method.

  The present invention is an apparatus that automatically arranges a plurality of electronic images in a specific area, and sets the center position as a reference for the arrangement angle and arranges each image based on an angle obtained by multiplying the golden angle by an integer.

  The present invention is also characterized in that the angle of the arrangement position is a golden angle. Here, the golden angle is an angle obtained by dividing the circumference 360 ° into the golden ratio 1: (1 + v5) / 2, and is an angle obtained by 360 ° / (1+ (1 + v5) / 2) = 1377.57764. is there. The golden ratio is known to represent the aspect ratio of the most balanced and beautiful rectangle. As for the golden angle, it is known that, for example, leaves can be removed from the branches for each golden angle in the stratification to reduce the overlap of the leaves and optimally share sunlight and rain. Therefore, according to the present invention, it is possible to determine the arrangement position of each image with a simple arithmetic process, and it is easy to reduce the overlapping of each image, so that an efficient arrangement can be obtained.

  The present invention is also characterized in that the golden angle is 130 ° to 144 °. Here, when the number of images is small, the arithmetic processing can be further simplified by approximating the golden angle with a rational number, for example.

In the present invention, the arrangement angle changing means increments an integer multiple of a predetermined angle used as a reference with respect to the image for which the arrangement position is determined by a predetermined amount, and then the arrangement angle determining means The arrangement angle of the image is re-determined, and the arrangement position determination means determines the arrangement position of the image at a position where the image contacts the arrangement reference area determined by the arrangement reference area determination means.
According to this, since the integer multiple of the predetermined angle is incremented by a predetermined amount and the arrangement angle of each image is re-determined, the arrangement position of the image is determined at a position where the image is in contact with the arrangement reference region ( In other words, since it is arranged near the periphery of the arrangement reference area), it is possible to increase the possibility of arrangement without overlapping, and moreover, the arrangement reference area (or a specific area than the center position around which the arrangement angle is based). A tendency to be easily arranged near the boundary of (region) is obtained.

<First Embodiment>
The best mode for carrying out the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram for explaining the configuration of the image arrangement apparatus according to the first embodiment of the present invention, and FIG. 2 is a flowchart for explaining an example of its operation. The image arrangement apparatus according to the present embodiment includes a general computer including a central processing unit, a storage device, a keyboard, a mouse, a display device, a recording device using an optical recording medium, and peripheral devices such as a printer and a digital camera. And a program for image arrangement processing executed on computer with predetermined system software. FIG. 1 shows each function of the image layout processing program divided into blocks.

  In FIG. 1 and FIG. 2, an image layout apparatus (image layout program) activated in accordance with a user (operator) operation is instructed by the layout area size acquisition unit 101 with the user using a graphical user interface or the like. The area size (specific area size) for arranging the processed image is acquired. Similarly, the arrangement image number acquisition unit 102 acquires the number of images to be automatically arranged instructed by the user (step S101 in FIG. 2).

The image size setting unit 103 sets the change ratio (reduction ratio or enlargement ratio) of the image size (width and height) when arranging each image from the acquired number of images and area size (step S102). At this time, the size of each image is, for example, about several tens% (20 to 80%) of the value obtained by dividing the area size by the number of images (the maximum size allocated per image) if the images are the same size. Set to. Each image is arranged in a specific area (in the arrangement reference area) with a size set by the image size setting unit 103.
Further, when the sizes of the images are different, the image size setting unit 103 adds up the sizes of the images to be arranged, divides the integrated value by the region size, and the division result is several tens of% similar to the above. In this way, the image size change ratio (reduction ratio or enlargement ratio) is obtained. This reduction rate or enlargement rate is common to all images, that is, the size is uniformly changed.

  The arrangement reference area revision unit 104 sets an arrangement reference area as a reference for actually arranging an image from the area size acquired by the arrangement area size acquisition unit 101 (step S103). A method for determining the arrangement reference area may be set to 95% of the area size, or may be set to a value other than subtracting a predetermined value, for example, 5% of the area size width, from the area size width and height. It is done. In the present embodiment, each image is arranged in this arrangement reference area.

The initial position setting unit 105 determines an initial position (X0, Y0) of an image to be arranged first (
Step S104). As a method for determining the initial position, generation by random numbers, setting at the center in the region, setting by user action, acquisition from predefined definition data, and the like can be considered. In addition, when an image is arranged with respect to the initial position, the center of the image is matched with the initial position, the center of gravity of the image is matched with the initial position, or the center of the circumscribed rectangle of the image is matched with the initial position. . The arrangement angle center position setting unit 106 determines the position of the center position (reference point) of the arrangement angle (step S105). The method for determining the arrangement angle center position can be set at an arbitrary point in the arrangement area regardless of the initial position of the image to be arranged first. For example, a method is conceivable in which the center points of nine rectangles formed when the arrangement area is divided into three in the vertical and horizontal directions are used as the arrangement angle center positions.

  The arrangement angle revision unit 107 initializes the golden angle coefficient m (m is an integer of 0 or more) to 0 (step S106). The golden angle is an angle obtained by dividing the circumference 360 ° into the golden ratio of 1: (1 + v5) / 2, and is obtained as 360 ° / (1+ (1 + v5) / 2) = 1377.57764. This golden ratio is known as representing the aspect ratio of the most balanced and beautiful rectangle. As for the golden angle, it is known that, for example, by removing leaves from the branches for each golden angle in the stratification, the overlap can be reduced and sunlight and rain can be optimally shared. In the present embodiment, the arrangement angle of each image is determined based on an angle obtained by multiplying the golden angle by m (integer multiple), and the arrangement position of each image is determined according to the overlap of the images based on the determined angle. I have to. The arrangement angle setting unit 107 determines, from the golden angle and the coefficient m, the direction θ (the arrangement position angle θ) of the currently arranged image by calculating θ = m × golden angle (step S107).

For example, regarding the angle of the arrangement position, if the position of the line segment extending in the horizontal direction from the center of the image arranged at the initial position is 0 °, the direction θ is calculated clockwise based on this, and the inclination of this θ Place the image on the axis.
Further, the inclination when arranging each image may be set by the golden angle. At this time, if it is tilted to the set threshold angle, it may be controlled to tilt in the opposite direction.

  In the present embodiment, as a specific example of the golden angle, a value range of 130 ° to 144 ° is used. However, as the value of the golden angle, about 137.5 ° calculated from the Fibonacci sequence is the most preferable case.

  The image position calculation unit 108 arranges images in the direction determined by the arrangement angle setting unit 107 and at a position (X, Y) where the outer frame of the image touches the arrangement reference region, and sets the distance between the images to L ( Variable) (step S108). Further, the variable N is initialized to 0 (step S109).

  The overlap detection unit 109 compares the image position (X, Y) obtained by the image position calculation unit 108 with the positions of other images calculated so far, and determines whether or not the images overlap (step S110). ). If it is determined by the overlap detection unit 109 (“No” in step S110), 1 is added to the variable N (step S111), and the image position calculation unit 108 calculates a new image position again. . Here, when the variable N is 1 (“Yes” in step S112), the golden division point 0.618 obtained by the golden ratio 1: (1 + v5) / 2 is added to the value of the distance L between the images stored in step S108. The multiplied value (L × 0.618) is set as a new inter-image distance and the image is arranged (step S113), and the process returns to step S110 to determine whether or not it overlaps with another image.

  On the other hand, if the variable N is 2 (“No” in step S112 to “Yes” in step S114), the image ratio distance L stored in step S108 is set to the golden ratio 1: (1 + v5) / 2. A value (L × 0.382) obtained by multiplying another golden division point 0.382 to be obtained is set as a new inter-image distance and an image is arranged (step S113). Judge whether or not.

  When the overlap detection unit 109 determines that there is no overlap with another image (“Yes” in step S110), the out-of-region detection unit 110 enters the image within the arrangement reference area determined by the arrangement reference area setting unit 104. It is determined whether or not (step S118). When it is determined that the out-of-region detection unit 110 protrudes, even when the overlap detection unit 109 determines that there is no overlap with other images, calculation by the arrangement angle setting unit 107, the image position calculation unit 108, and the like is performed. It should be noted (from “No” in step S116 to step S107 via steps S117 and S118). For example, the arrangement angle setting unit 107 increments the golden angle coefficient m by 1 (step S118), and the same calculation is performed for the new golden angle by the arrangement angle setting unit 107, the image position calculation unit 108, and the like ( Steps S108 to S115). At this time, if m exceeds 144 (“No” in step S117), that is, since the angle has returned to m = 0, the process returns to step S105 to determine the position of the center point of the new arrangement angle. Similar calculations are performed. Here, the processing of steps S117 to S118 is processing that functions as an arrangement angle changing unit, and is performed within the block shown in FIG. 1 such as the arrangement angle setting unit 107, the out-of-region detection unit 110, or the like. It can be done with other functional blocks.

  here. The process of step S117 will be described. For example, when the golden angle setting value is 137.5 °, the arrangement angle θ when the direction is changed 144 times is θ = m × 137.5 ° = 144 × 137.5 ° = 360 ° × 55. This coincides with the arrangement angle θ = 0 ° when m = 0. That is, even if the coefficient m is changed when m = 144 or more, the calculation is repeated in the same direction as that already calculated. Therefore, in step S117, it is determined whether there is still a direction in which the image position is not calculated at the same arrangement angle center position by determining whether the coefficient m matches 144. When there is a direction in which the image position is not calculated, the arrangement angle θ is set to another direction, and the image arrangement processing is performed.

  In addition, when the variable N is 3 or more (“No” in step S114), the same processing as that performed when the out-of-region detection unit 110 determines that the variable N protrudes is performed.

  If the overlap detection unit 109 determines that there is no overlap and the out-of-region detection unit 110 determines that the region does not protrude outside the arrangement reference region (“Yes” in step S110 and “Yes” in step S116), step S108, The arrangement position of the image is determined at the position calculated by the image position calculation unit 108 in S113 and S115. The initial position setting unit 105 or the like checks whether there is still an image whose arrangement position is to be calculated. If an unprocessed image remains, the arrangement calculation is continued (from “NO” in step S119 to step S106). . On the other hand, if all the images have been processed, the processing ends (“Yes” in step S119).

FIG. 3 shows an example in which six images 4, 5, 7, 8, 10, 11 are arranged in the arrangement reference area 2 in the specific area 1. In this example, with the arrangement angle center position 3 as a reference point, the first image 4 is arranged at a position in contact with the reference arrangement area 2 at an angle of 0 ° (m = 0). Images 5, 7, 8, 10, and 11 indicate the second to sixth images. m = 0 to m = 5 are codes representing golden angle coefficients, and each code is described in the vicinity of a chain line indicating the extending direction of the golden angle multiplied by m. In this example, the second image 5 is also arranged in the direction of the golden angle of m = 0. The second image 5 is a position obtained by dividing a straight line (distance L) connecting the arrangement center of the first image 4 to the arrangement angle center position 3 using the golden ratio (from the arrangement angle center position 3 to L × 0.618). Position). Further, since the third and fourth images 7 and 8 cannot be arranged at an angle of m = 1, they are arranged at an angle of m = 2 (arrangement angle θ = 275 °). Further, since the fifth and sixth images 10 and 11 cannot be arranged at an angle of m = 3 to 4, they are arranged at an angle of m = 5.
Note that at an angle of m = 0, 2, there is an overlap with other images at the position L × 0.382 (areas 6 and 9 indicated by broken lines) from the arrangement angle center position 3, and therefore the image is not arranged. Absent.

In FIG. 3, images having the same size and orientation are described, but as described above, the size of the image to be arranged is determined by the size of the reference arrangement area, the number of images to be arranged, and the size of each image. In order to obtain the change rate to change and adjust the size of each image, as shown in FIG. 4, even if four images having different sizes are arranged, a uniform arrangement in a predetermined reference arrangement area is possible. It is.
Similar to FIG. 3, there is no space at the angle of m = 1, 3, 5 and no image is arranged. Since the image 20 cannot be arranged at an angle of m = 0, 2 in terms of size, the image 20 is arranged as an image 21 at an angle of m = 5. Further, since it overlaps with the image 21, the image 22 is arranged at a position of L × 0.618 on a straight line with an angle of m = 2, and the image 23 is arranged at a position of L on a straight line with an angle of m = 0. Yes.

  The present invention rules the regular beauty that appears in the natural world and can reproduce the natural beauty that mankind has been accustomed to for many years. Therefore, even when applied to an electrophotographic album, it is possible to reproduce a beautiful arrangement that people feel more natural.

  In addition, since iterative calculation is almost unnecessary and the position where the image can be taken is determined as soon as the arrangement direction is determined, the arrangement calculation can be easily performed even in a device having a small memory capacity or CPU power. Have

  As a modification of the above embodiment, the golden division point is used in steps S113 and S115 of FIG. 2, but it may be simply 2/3, 1/3, or the like.

  In addition, the arrangement position in the above embodiment is 0 (when an image is arranged at the center position of the arrangement angle) or 1 (which is determined from the center position of the arrangement angle and the boundary of the specific area or the arrangement reference area) or 1 ( It can be considered that an image is arranged at a position that is in contact with the boundary or the like, or is determined to be a position divided by a value obtained by a substantially golden ratio, but one division point on a straight line (for example, L × 0) .. 382)) to a plurality of three or more points.

<Second Embodiment>
Next, a second embodiment of the present invention will be described. The configuration of the second embodiment is the same as that of the first embodiment. In the second embodiment, a display image in which a plurality of images are arranged at different intervals is displayed on a display screen of a CRT at a predetermined time interval by the image processing of the first embodiment. For example, a screen saver This is a configuration of an image processing apparatus that performs such processing. The operation of the second embodiment different from that of the first embodiment will be described with reference to FIG. FIG. 5 is a flowchart for explaining an operation example as a screen saver for displaying a slide show (registered trademark) display image.

  The image processing apparatus according to the second embodiment is provided in a user terminal (for example, a personal computer, a workstation, a server apparatus, or the like), and is operated by a user who is an operator of the user terminal or by driving a timer. The image arrangement processing for the display screen, that is, the screen saver processing of FIG. 5 is started. Here, the timer driving means that when the user does not operate the computer from the input device for a predetermined time set in advance in the inside, the internal timer detects that the predetermined time has elapsed. This means that the image processing apparatus starts the screen saver process on the display screen, that is, starts the screen saver process.

  In the image arrangement apparatus, when the screen saver process is started, the arrangement area size acquisition unit 101 uses a graphical user interface or the like to set the size of an area where an image set in advance by the user, that is, the display of the user terminal. The area size on the screen is read from, for example, an internal storage unit. At this time, the arrangement image number acquisition unit 102 reads the number of images to be automatically arranged set by the user through the same processing as the acquisition of the area size from the internal storage unit (step S501).

  Next, the image size setting unit 103 sets the size (width and height) for placing each image as a process of placing the number of images in the region size from the number of read images and the region size. (Step S502). This setting process is performed, for example, by reading from a table of the number of images and the area size and the image size corresponding to them.

  Then, the arrangement reference area setting unit 104 sets an arrangement reference area serving as a reference for actually arranging images from the area size acquired by the arrangement area size acquisition unit 101 (step S503). This arrangement reference area determination method may be set to 95% of the area size, or set to a value obtained by subtracting a predetermined value, for example, 5% of the area size width, from the area size width and height. It is done.

  Next, the arrangement determination processing for all images in step S504 is performed in the same manner as in steps S104 to S119 of the first embodiment shown in FIG. 2, and the arrangement position of each image on the display screen is determined. Here, in step S104, the initial position determination of the first image in the arrangement reference area is not performed by the user setting process, but the initial position setting unit 104 randomly generates a processing arrangement position using a random number. Alternatively, it is determined by a predetermined algorithm that is set such that a predefined position is set as an initial arrangement position.

  When step S504 ends and the arrangement positions of all the images are determined, the image processing apparatus determines whether to end the screen saver. This determination process causes the image processing apparatus to end the screen saver process when the image processing apparatus detects an instruction to end the user's screen saver or when the user detects any operation on the computer. At this time, if the image processing apparatus does not end, the image processing apparatus may return to the process of step S504 after a predetermined time has elapsed (control of the display time of the screen after the arrangement in the screen saver process).

In the above-described example, the number of images and the area size arranged on the display screen by the image processing apparatus are fixed after the screen saver process is once started.
However, for example, in the calculation of the arrangement of the image for each repetition, a process for changing the number of images at a predetermined ratio with respect to the arrangement image number acquisition unit 102, and the arrangement reference area setting unit 104 A process such as a process of changing the size may be added.

  With the addition of this processing, the screen saver processing can display a plurality of images on the display screen with a more characteristic arrangement result. When these processes are added, the image processing apparatus does not return to the process of step S504, but returns to the process of step S502, and the image size setting unit 103 determines the area size from the number of read images and the area size. Needless to say, as the process of arranging the number of images, the process of setting the size when arranging each image is performed.

  In addition, the screen saver process has been described as an example, but the process of sequentially displaying a plurality of images on the display screen while changing the arrangement position of the plurality of images on a display screen for each predetermined period of time by a slide show (registered trademark) display algorithm. Can be used in any processing.

  The first and second embodiments of the present invention can be realized by a computer and a program executed by the computer, and the program is distributed via a communication line or a computer-readable recording medium. It is possible. Further, the units shown in FIG. 1 can be further divided, integrated, or distributed via communication lines.

  In the above description, the present invention has been described based on the golden angle. However, the aspect of the present invention can also be regarded as having the following characteristics. That is, the present invention automatically determines the arrangement of one or a plurality of images within a specific area (or within an arrangement reference area set from the specific area), and uses the Fibonacci sequence. It can be regarded as a feature that determines the arrangement of. Here, when the Fibonacci sequence is used, it can be considered that the arrangement of the image is determined by applying the Fibonacci sequence to the angle.

Alternatively, when the Fibonacci sequence is used, the image arrangement may be determined by applying the Fibonacci sequence to the distance. Alternatively, although the embodiment is not particularly described above, when the Fibonacci sequence is used, the arrangement of the images can be determined by applying the Fibonacci sequence to the direction (tilt) of the image. Alternatively, when using the Fibonacci sequence, apply an equiangular spiral (a straight line connecting a pole and any point on the curve that always intersects the tangent of the curve at that point) with the Fibonacci sequence. It may be characterized by determining the arrangement.
