Description

  The present invention relates to an exhibition set and an exhibition method, and more particularly to an exhibition set and an exhibition method for exhibiting ornamental objects such as printed matter and paintings.

  Conventionally, a pseudo window as described in Patent Document 1 is known as an example of an exhibition set. This is installed in an environment where windows can not be installed to ensure quietness and defense against secret leakage in conference rooms, etc., and displays an image of a landscape that can exist outside the window on the display, A pseudo window frame is installed in front of it. This makes it possible for a person in the room to have a simulated experience as if viewing an actual outdoor landscape.

JP 2008-297803 A

  However, in the exhibition set described in Patent Document 1, there is a case where “realism” when viewing the scenery outside the displayed window is poor. Simply arranging the windows has a lack of realism, and the effect of making a simulated experience as intended in Patent Document 1 is not sufficient. Because, in order to effectively produce “realism” such as three-dimensionality and immersive feeling in ornaments, the positional relationship between the audience, the ornaments, and the ornamental staging material that directs the exhibition environment in the exhibition set is appropriately controlled. Because it is important. In Patent Document 1, not only the relationship between a window as an appreciation staging material, an ornamental object, and an audience is not controlled, but also the positional relationship is destroyed by opening and closing the staging material (window), so the sense of reality is reduced. Will occur.

  In order for a person in the room to have a pseudo-experience as if viewing an outdoor landscape, it is generated by an ornament that is a display unit and an ornamental effect material that is a pseudo window door when the person in the room moves. A sense of reality such as a sense of depth and immersion caused by motion parallax is important. This is the same not only in the above pseudo window but also in a general set.

  However, in the above-mentioned exhibition set, it is an ornament that exists at the back and the brightness shown by the window frame that is a member on the front for effectively generating motion parallax, which is an important element for feeling a sense of reality. There is a concern that the brightness relationship indicated by a certain display unit is not appropriate.

  The present invention is an exhibition capable of improving the sense of reality by effectively generating motion parallax by making the relationship between the brightness of the members present in the front of the exhibition set and the ornamental object appropriate. The purpose is to provide a set and display method.

  To this end, the present invention is an exhibition set for viewing ornamental objects, and is an ornamental effect material that is arranged on the viewing position side with respect to the ornamental object and the ornamental object and shields at least a part of the ornamental object The ornamental effect material is fixed so as not to change the relative positional relationship with the appreciation object, and the ornamental effect material and the ornamental effect material are at least part of the ornamental object. In accordance with the brightness of at least one part of the ornamental effect material, a brightness light / dark relationship between at least a part of the ornamental material and at least a part of the ornamental effect material is defined.

  According to the above configuration, the viewing area of the appreciation object and the viewing effect material are changed when the viewer moves by making the brightness relationship between the member existing in the front of the exhibition set and the ornamental object appropriate. By effectively generating motion parallax generated by the viewing area, it is possible to improve the sense of reality.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that the constituent elements described in the following embodiments are merely examples, and it is needless to say that the scope of the present invention is not limited thereto.

  Fig.1 (a)-(d) is a figure explaining the exhibition set which concerns on one Embodiment of this invention. In these figures, reference numeral 101 denotes an ornament, which can be a sheet or a panel on which an image is recorded or a picture is drawn by an inkjet printer. This ornamental object 101 is fixed to an exhibition surface 103 such as a wall. The ornamental object may be an image directly recorded or drawn on the display surface. Reference numeral 102 denotes an ornamental effect material, which is arranged on the side of the ornamental position with respect to the ornament, and is formed by sticking a uniform color paper on the surface of the wooden board. The ornamental effect material is not limited to this form, and for example, a wooden board that has been subjected to a treatment such as painting, a color plastic plate, a metal plate, or the like can be used. As shown in FIG. 1A, the ornamental effect material 102 is disposed at a relative position at a distance S from the ornamental object 101.

  FIG.1 (b) is the figure which looked at the display set of this embodiment from the front, and the display surface is abbreviate | omitted. FIG. 1C is a view of the ornamental object, and FIG. 1D is a view of the ornamental effect material 102 as viewed from the front. As shown in FIG. 1C, the ornamental object 101 includes images to be viewed 101a and 101b. These viewing object images 101a and 101b are objects that may be viewed with particular attention, especially when the viewer looks at an ornament. In the example shown in FIG. 1D, the ornamental effect material 102 has a frame shape such as a predetermined window frame, but is not limited to this form. As will be described in detail later, the ornamental performance material acts to shield a part of the ornament from being viewed by the viewer. This produces the effect of “parallax” and “feel of depth”. A frame-shaped ornamental effect material 102 shown in FIG. 1 (d) includes vertical effect materials 102a and 102b and horizontal effect materials 102c and 102d having widths d2 and d3, respectively. A space for viewing an ornament is formed between the vertical effect material 102a and the vertical effect material 102b, and in the example shown in the figure, has a width d1. The widths d2 and d3 of the vertical effect materials 102a and 102b can be set to a width or an arrangement so that the viewer does not visually recognize the boundary 105 in the horizontal direction. Note that the “boundary” is intended to include the boundary between the margin and the image when the exhibit 101 has a margin around the image like a photograph. As will be described later, the brightness shown by the vertical effect materials 102a and 102b and the horizontal effect materials 102c and 102d is appropriately determined in relation to the brightness shown by the ornamental object 101. Furthermore, the ornamental effect material in the present embodiment is fixed between the ornament and the viewer. By using the ornamental production material, it is possible to produce a “realistic feeling” such as a three-dimensional effect, a sense of depth, and a sense of immersion in the ornament. In the present invention, in order to sufficiently obtain the effect, the appropriate positional relationship between the ornamental effect material, the ornamental object, and the viewer is controlled. Therefore, it is easier to obtain the effect if the ornamental effect material is fixed at an appropriate position. For example, if the ornamental effect material changes its shape or position at the time of viewing, there is a concern that the feeling of depth or the like may be reduced, and the presence of the exhibition set may be impaired. Here, it may be fixed with an adhesive or a jig, etc., but without doing so, display the viewing effect material at the desired position on the floor and display it so that the position can be maintained. I just need it. You may be reminded to prevent the viewer from moving the appreciation material along with the exhibition, or if the appreciation that the viewer should move and you do not move the appreciation material from yourself, place it flat. You may keep it.

  Moreover, since it is desirable that the ornamental effect material is fixed for the reason described above, it is better that the material for the ornamental environment is stationary than the material for which the actual environment is not very stationary. For example, it is conceivable that an ornamental effect material imitating an animal may cause a sense of incongruity as it continues to be stationary, and it is desirable to use a material that is stationary in an actual environment as an ornamental effect material of the embodiment. 2 (a) to 2 (c) are perspective views showing other forms of the ornamental effect material, and are the same as FIG. 1 (a). In these drawings, the display surface 103 is not shown.

  The ornamental effect material 201 shown in FIG. 2 (a) has three vertical effect materials 201a, 201b, and 201c. Cylindrical vertical effect materials 201a and 201b are arranged at both ends, and from the both ends in the center. A thin columnar vertical effect material 201c is arranged. Furthermore, the ornamental effect material shown in FIG. 2D is composed of two prismatic vertical effect materials 205 and 206 fixed between the center of the appreciation object 101 and the left and right ends, respectively. These are separated from the appreciation object at a set interval. The distance from the surface of the two viewers on the viewer side to the viewing object 1010 is “S”. Also, the ornamental effect material shown in FIG. 2B is composed of two tree-like vertical effect materials 202 and 203. The distances S1 and S2 with these viewing objects are different. Furthermore, the ornamental effect material 204 shown in FIG. 2C has the effect material in the depth portions on both sides in the horizontal direction of the ornamental effect material, and there is no effect material on the upper and lower sides in the vertical direction. )belongs to. In FIG. 2, the ornamental object is present on a flat display surface, but the shape of the ornamental object is not limited to this, and may be present inside a cylinder or a dome-shaped surface surrounding the viewer. Even in such a case, the feature of the present embodiment is that the ornamental effect material is fixedly arranged between the viewer and the ornament.

  As described above, the ornamental effect material according to the embodiment of the present invention includes at least a vertical effect material, and this vertical effect material shields a part of the ornamental object from the viewer, The arrangement and the like can be determined so that the viewer cannot visually recognize the boundary between the ornamental object and the display surface.

  FIG. 3 illustrates, in particular, the relationship between the ornamental object 101 and the ornamental production material 102 and the relationship between the viewer 301 who appreciates the ornamental object and the image 101a to be viewed in the ornamental object of the exhibition set according to the present embodiment. It is a figure to do. FIG. 3 is a view similar to FIG. 1A, but in FIG. 3, vertical effect materials 102c and 102d, which are ornamental effect materials, are added.

  When the viewer 301 (distance x from the viewing object) views the viewing object 101, first, the focus adjustment function of the human eye is considered. In other words, the depth can be recognized by the focus adjustment function of the human eye, although there are individual differences. Generally, it is 2 meters, and when viewing an ornament at a distance shorter than this distance, the ornament 101 can be recognized by the focus adjustment function. Is recognized as being present on a plane, and a sense of depth cannot be obtained. From this point, when it is set as the recommended viewing range 302 that is recommended as the viewing range by the viewer, the distance 304 closest to the viewing object 101 is set to 2 meters or more. On the other hand, when the viewer gazes at the center of the viewing target image 101a of the viewing object 101 under the condition of the distance 305 where the viewing object and the viewing party are farthest, the horizontal end 104 (the display surface 103 and the display surface 103). Is equal to or smaller than the distance within the horizontal field of view of the viewer 301. In other words, the human field of view varies between individuals, but generally, the range that can be seen simultaneously by both eyes is about 120 degrees, and at a distance longer than the farthest distance, the entire view of the ornament enters the viewer's field of view. The viewer feels that the ornament is a two-dimensional object such as a printed matter, and the presence is impaired.

  In this case, when the boundary is set to the distance itself that falls within the range of the viewer's horizontal field of view, as described above, there is a risk that the sense of reality is impaired. Therefore, in the present embodiment, the boundary 105 is prevented from entering the viewer's field of view by the vertical effect material (102a, 102b, etc.) of the effect effect material 102.

  The ornamental effect material 102 according to the embodiment of the present invention produces a “realistic” effect such as a three-dimensional effect and an immersive feeling when the ornamental object 101 is viewed. As its function, (1) motion parallax (2) shielding, relative size and density.

  The “motion parallax” is a parallax generated by the movement of the viewer's viewpoint or the image to be viewed (viewed object). If the ornamental staging material exists between the viewer and the ornament, when the viewer moves while gazing at the ornament (the image to be viewed), the amount of change in the field of view is large ( The speed is high), and the amount of change in the ornament is small (slow speed). This difference in change amount or change speed is the action of motion parallax.

  4A to 4F are diagrams illustrating motion parallax according to the present embodiment. From the state shown in FIG. 4 (a), as shown in FIG. 4 (b), the viewer 301 represents the vertical effect material 102a of the ornamental effect effect material (representing the vertical effect material as “102a”. When moving in the negative direction of the X axis while gazing at (505), the shielding position of the viewing target image 101a by the vertical effect material 102a changes as shown in FIG. 4 (c). Further, as shown in FIG. 4D, when the vertical effect material 102a is moved in the positive direction of the X-axis while gazing at (507), as shown in FIGS. The shielding position of the viewing target image 101a of the ornamental object 101 by the vertical rendering material 102a of the ornamental effect rendering material changes. In this way, according to the movement of the viewer, there is a difference between the amount of change in the viewing effect material within the field of view of the viewer and the amount of change in the viewpoint on the ornament, and this difference allows the viewer to watch Perceive depth in the image. In this way, by using the ornamental effect material, it is possible to produce an “realistic” effect such as a three-dimensional effect or an immersive feeling with respect to the ornamental object.

  “Occlusion” is a human being who perceives that a certain object is present before another object when a certain object is hiding a part of another object among a plurality of objects. It is a kind of stereoscopic perception. In this embodiment, by placing the ornamental effect material 102 between the ornamental object 101 and the viewer 301, the viewer perceives the depth between the ornamental effect material and the ornamental object 301, and further from the distance between the ornamental object and the ornamental effect material. Depth is perceived empirically by the spatial phase arrangement of a plurality of images to be viewed.

  It should be noted that the position where the ornamental object is “shielded” using the ornamental effect material is, for example, a position where the image to be viewed constituting the “perspective” such as “road” 101e shown in FIG. . As with the “motion parallax” and “shielding” described above, it is desirable to arrange an ornamental effect material so that the viewer can view the “linear perspective” element in the ornament.

  In the following, the method for determining the relationship between the brightness of the ornamental effect material 102 and the brightness of the ornamental object 101 according to an embodiment of the present invention will be described using the display set shown in FIGS. 5A and 5B as an example. To do. FIGS. 5A and 5B are diagrams showing a box-shaped display set similar to the display set shown in FIG.

  When viewing the exhibition set described above, a contrast phenomenon of brightness occurs in humans due to the action of the visual system called side suppression. FIG. 6 is a diagram for explaining this phenomenon. The area 601 and the area 602 shown in FIG. 6 have the same physical brightness. In spite of this, the brightness perceived by human eyes is that the area 601 looks darker than the actual area and the area 602 appears brighter than the actual brightness due to the side suppression. This is because the nerve cell group in the visual system is suppressed with another nerve cell group that is close to or adjacent to each other, and the nerve cell group that is exposed to light responds strongly, and the activities of the surrounding nerve cell groups This is due to the suppression. Specifically, in the example shown in FIG. 6, the region 603 is brighter white, so that the nerve cell group that reacts to the region 603 has a strong response, and as a result, the nerve cell group that reacts to the region 601 is suppressed. Is done. As a result, the gray in region 601 will appear darker. On the other hand, since the region 604 is darker black, the nerve cell group that reacts to the region does not receive light and the nerve cell group does not work. As a result, the nerve cell group that reacts to the region 602 is not suppressed, and the gray of the region 202 looks brighter than when there is white around the region 601.

  The work of the visual system described above has a great influence on the sense of presence felt by the viewers who appreciate the exhibition set. Therefore, the present embodiment improves the sense of reality by making the relationship between the brightness of the viewing area of the ornamental object and the viewing area of the viewing effect material appropriate for the viewer from the viewing position.

(First embodiment)
FIG. 7 is a diagram illustrating the viewing area and the viewing position of the viewer in the ornamental object and the viewing effect material according to the first embodiment of the present invention. In the present embodiment, as shown in FIG. 7, the ideal viewing position 301 of the viewer in the exhibition set is one specific point. That is, it is a position where the effect of the determined brightness relationship described below can be most favorably obtained. When viewing from this position, the entire area of the ornamental object 101 can be seen, and that area becomes the viewing area (hereinafter referred to as viewing area A1). The ornamental effect material 102 uses the front area as an ornamental area (hereinafter referred to as an ornamental area B1). In the example shown in FIG. 7, the viewer can see only the front of the viewing effect material from the viewing position 301. Therefore, the viewing area B1 is the front portion of the viewing effect material 102 shown in FIG.

  Hereinafter, an example will be described in which the brightness relationship between the viewing area A1 and the viewing area B1 is determined, and the average brightness value of the viewing area B1 is determined from the average brightness value of the viewing area A1.

First, a luminance value is obtained as the brightness of the viewing area A1. In this embodiment, the luminance value of each pixel is obtained from the original image (RGB: 8 bits each) for obtaining the ornament for the ornamental area A1 (all areas of the ornament) by the following equation (1). .
Y = 0.299 × R + 0.587 × G + 0.114 × B (1)

  Next, the average luminance value of the viewing area A1 is calculated by taking the sum of the luminance values of all the calculated pixels and dividing the sum by the total number of pixels.

  Next, in order to determine whether the original image is a bright image or a dark image, an intermediate value of prescribed luminance values is obtained. In the present embodiment, since the original image is RGB 8-bit, the upper limit value of the luminance value calculated from the original image is 255 and the lower limit value is 0, so the intermediate value of the luminance value is 128. Then, the brightness of the viewing area A1 (the brightness of the current image) is determined. In the present embodiment, the above-described average luminance value and intermediate value are used to determine “bright image” if the average luminance value is equal to or higher than the intermediate value, and “dark image” if the average luminance value is less than the intermediate value.

  Next, the relationship between the brightness of the viewing area A1 and the viewing area B1 is determined by determining the range of the average luminance value of the viewing area B1 according to the determination result. When the viewing area A1 is determined to be a bright image, the brightness of the viewing area B1 is set so that the average brightness value of the viewing area B1 is equal to or less than the average brightness value (less than the average value) of the viewing area A1. On the other hand, when it is determined that the viewing area A1 is a dark image, the brightness of the viewing area B1 is set so that the average luminance value range of the viewing area B1 is equal to or higher than the average luminance value (average value) of the viewing area A1. To do. Then, the brightness of the ornamental effect material is determined by determining the average luminance value of the ornamental area B1 as described above.

  In this embodiment, as an example, when the ornamental object 101 is determined to be a bright image, the brightness of the ornamental area B1 is black (luminance value 0), and when it is determined to be a dark image, the brightness of the ornamental area B1 is determined. Let the thickness be white (luminance value 255). FIGS. 8A and 8B are diagrams for explaining the brightness of the appreciation object and the appreciation effect material based on the brightness determination according to the present embodiment. FIG. 8A shows a case where a bright image is determined in the above determination, and the viewing area B1 is a “black” color. FIG. 8B shows a case where it is determined that the image is a dark image in the above determination, and the viewing area B1 is “white”. In the present embodiment, the ornamental area B1 has a uniform color, and the average luminance value can be directly measured and determined according to the color. Note that when the ornamental effect material is a wallpaper on which a printed matter is pasted, the average luminance value of the viewing area B1 can be calculated from the luminance value of the original image to be printed in the same manner as the viewing area A1. .

  FIG. 9A shows a histogram of the image of the viewing area A1 when the viewing area A1 is determined to be a bright image, and FIG. 9B shows the human perception of brightness in terms of input / output relationships. is there.

  When it is determined that the viewing area A1 is a bright image, in the present embodiment, as shown in FIG. 9A, the average luminance value of the viewing area B1 is the highest in the range less than or equal to the average luminance value of the viewing area A1. A dark luminance value (0: black) is assumed. As a result, as shown in FIG. 9B, the viewing area A1 is viewed as a broken line (the solid line indicates a linear relationship between the input and output, and there is no effect of the present embodiment). Perceive. That is, the apparent dynamic range is widened perceptually so that the broken line appears above the solid line. In this way, by making the average brightness of the viewing area B1 darker than the average brightness of the viewing area A1, on the human visual system, the brightness comparison is performed in the bright side area indicated by the area 901 in FIG. 9B. The effect can be increased. As a result, the perceptual dynamic range can be particularly increased with respect to the main bright portion of the image shown in the region 902 of FIG.

  On the other hand, FIG. 10A shows a histogram of an image of the viewing area A1 when the viewing area A1 is determined to be a dark image, and FIG. 10B shows human perception with respect to brightness in an input / output relationship. FIG.

  When it is determined that the viewing area A1 is a dark image, in the present embodiment, as shown in FIG. 10A, the average luminance value of the viewing area B1 is the highest in the range equal to or higher than the average luminance value of the viewing area A1. A bright luminance value (255: white) is used. As a result, as shown in FIG. 10B, the viewing area A1 is viewed as a broken line (the solid line is a state in which the relationship between the input and the output is linear and the effect of the present embodiment is not effective). Perceive. That is, the apparent dynamic range is widened perceptually so that the broken line appears below the solid line. In this way, by making the average brightness of the viewing area B1 brighter than the average brightness of the viewing area A1, on the human visual system, the contrast of the brightness in the dark side area shown in the area 1001 of FIG. The effect can be increased. As a result, the perceptual dynamic range can be particularly increased for the main dark part of the image shown in the area 1002 of FIG.

  The effect of the light / dark relationship described above is smaller as the distance (difference) between the average luminance value of the viewing area B1 and the average luminance value of the viewing area A1 is smaller, and the effect is larger as the distance is larger.

  As shown in this embodiment, the perceptual dynamic range of the ornamental area A1 of the ornamental object can be expanded by appropriately determining the relationship between the brightness of the ornamental area A1 and the ornamental area B1. Thereby, by effectively generating motion parallax by the viewing area A1 and the viewing area B1, a sense of reality such as a feeling of depth and immersion in the exhibition set is improved. In addition, widening the dynamic range improves contrast and gradation discrimination and enhances the sense of reality.

  When the ornamental object is not a printed object and there is no original image data such as a picture, a brightness index such as a luminance value can be directly measured.

(Second Embodiment)
The second embodiment of the present invention is different from the first embodiment in that the viewing position of the viewer who receives the effect of the brightness relationship when viewing the exhibition set is within the recommended viewing range 701 in FIG. As shown, it is a point having a certain area and a brightness of the viewing area is adjusted by illumination. In the present embodiment, the light / dark determination method is also determined from the difference between the intermediate value and the upper limit value / lower limit value.

  FIG. 11 is a diagram for explaining the viewing area and the viewing area of the viewer in the ornamental object and the viewing effect material according to the second embodiment of the present invention. As shown in FIG. 11, the viewing area B2 of the viewing effect material 102 is the front surface thereof. Also, the viewing position of the viewer is an arbitrary position within the range shown in the area 1101. For this reason, in this embodiment, when an ornamental object is viewed from an arbitrary position within the predetermined range, an invisible portion is generated, so that the region that can be viewed from all the regions within the predetermined range (broken line 1201 in FIG. 12). Is a viewing area A2.

  First, a luminance value is obtained as the brightness of the viewing area A2. In the present embodiment, as shown in FIG. 13, the ornamental object 101 performs brightness adjustment using two illuminations 1301 and 1302, and the ornamental effect material 102 uses a single illumination 1303 to adjust brightness. I do. Therefore, in this embodiment, by using a measurement device such as a radiance meter for the viewing area A whose brightness has been adjusted by the two illuminations 1301 and 1302, measurement is performed at a predetermined pitch that can be measured by the measurement device. The brightness value of the viewing area A2 is acquired. The average luminance value of the viewing area A2 is calculated by taking the sum of the luminance values of the entire area thus obtained and dividing the sum by the number of measurement points.

  Next, in order to determine whether the image of the viewing area A2 is a bright image or a dark image, an upper limit value and a lower limit value of a specified luminance value are obtained. In this embodiment, white (the upper limit value of the luminance value of the ornamental object) that can represent the same material as the ornamental object 101 and black (lower limit of the luminance value of the ornamental object) that can also represent the same material as the ornamental object 101. Value), and the upper and lower limits of the luminance value are acquired.

  Then, the brightness (darkness of the image) of the viewing area A2 is determined. In the present embodiment, the determination is made using the average luminance value of the ornamental area A2 and the measured upper and lower limit values. The difference A between the upper limit value and the average luminance value and the difference B between the average luminance value and the lower limit value are calculated, and the difference A and the difference B are compared. If the difference A is greater (the difference A is greater than or equal to the difference B) ) Is determined as a “bright image”, and when the difference B is larger (when the difference A is less than the difference B), it is determined as a “dark image”.

  From this determination result, the process for determining the range of the average luminance value of the ornamental area B2 and the process for determining the brightness of the ornamental effect material are the same as in the first embodiment, as in the first embodiment.

  In the present embodiment, the average luminance value of the viewing area B2 can be obtained in the same manner as the viewing area A2 using a radiance meter in an environment where the brightness of the viewing area B2 is adjusted by the illumination 1303. Therefore, in the present embodiment, it is possible to adjust the average luminance value of the viewing area B2 to be within the determined range by adjusting the illuminance or the like of the illumination 1303.

  In this embodiment, compared with the first embodiment, the brightness contrast between the viewing area A2 and the viewing area B2 is configured by specializing the range (viewing area A2) that can be viewed by the viewer of the ornament. it can. Therefore, the perceptual dynamic range of the viewing area A2 can be expanded in a state more suitable for the viewing environment. Thereby, by effectively generating motion parallax by the viewing area A1 and the viewing area B1, a sense of reality such as a feeling of depth and immersion in the exhibition set is improved. In addition, widening the dynamic range improves contrast and gradation discrimination and enhances the sense of reality. In the first embodiment, when changing the brightness of the viewing area B1, for example, it is necessary to change the brightness of the ornamental effect material itself by changing a printed material to be pasted. The brightness of the viewing area can be adjusted by adjusting the illumination intensity or the like. As a result, the brightness relationship of the present invention can be configured more easily.

  In each embodiment described above, the brightness of the viewing area A and the viewing area B is determined by fixing the brightness of the viewing area A and changing the brightness of the viewing area B. The present invention is not limited to this. The brightness of the viewing area A is variable and the brightness of the viewing area B is fixed, or the brightness of the viewing area A and the brightness of the viewing area B are variable. However, it is sufficient that the relationship between the brightness of the viewing area A and the viewing area B determined by the present invention is satisfied.
