Description

Technical Field

[0001] The present invention relates to a method for visualizing the effect of a pest repellent.

Background Art

[0002] Pests such as mosquitoes recognize carbon dioxide, temperature, humidity, odor, etc. emitted by humans and animals, and sense a blood-sucking source. So far, various pest repellents have been studied to repel pests. Among them, as pest repellents, those containing N,N-diethyl-m-toluamide, picaridin, ethyl 3-(N-n-butyl-N-acetyl)aminopropionate, etc. as active ingredients are known. The pest repellent containing the above as an active ingredient acts on the sensory organs of pests such as mosquitoes and disrupts the sensing ability, making it impossible to sense the blood-sucking source. In other words, it is said that the pest repellent makes the area where it is applied imperceptible as if it were transparent.

[0003] Therefore, if uneven application of the pest repellent occurs, the unapplied areas can be sensed by pests, so that the effect of the pest repellent cannot be fully exerted. Thus, a demonstration method has been proposed in which a fluorescent material component is blended into the pest repellent and a black light is irradiated after applying the pest repellent to visualize the applied area (Patent Document 1).

[0004] The above demonstration method is carried out at a storefront, an event venue, etc., or on the Internet video. However, even when the above demonstration method is carried out, although general consumers can understand that uneven application is likely to occur when applying the pest repellent, the effect that pests cannot sense the area where the pest repellent is applied is not fully conveyed, and there is a problem that they cannot understand why the effect decreases when uneven application occurs.

Embodiments for Carrying Out the Invention

[0014] Specific embodiments of the present invention will be described below with reference to each figure.

[0015] First, as shown in FIG. 1(A), the upper arm portion 2 of a person as an object is placed in front of a background 1 whose entire surface is colored, for example, green. In this embodiment, video shooting of the upper arm portion 2 is started from this state by a camera. Next, as shown in FIGS. 1(B) and (C), a coating agent is applied to the upper arm portion 2 by the same coating method as the coating method of the pest repellent, and the portion where the coating agent is applied on the surface of the upper arm portion 2 is colored or discolored.

[0016] As for the coating method of the pest repellent for human body, various methods have been proposed, such as a method of spraying a liquid pest repellent onto the human body using an aerosol container, a mist container, etc., a method of applying a gel-like pest repellent by hand to the human body, and a method of wiping the human body with a sheet impregnated with a liquid pest repellent, and they can be properly selected according to the user's use and ease of application. Here, the same coating method means that the method of applying the above-mentioned pest repellent and the method of applying the coating agent are the same, and it is not necessary that the coating amount of the coating agent, the object to be coated, etc. be the same as the usage and dosage of the pest repellent.

[0017] In the example shown in FIG. 1, the coating agent is applied by the same coating method as the coating method using the aerosol container 3. The aerosol container 3 is filled with the coating agent. As the coating agent, for example, a pest repellent colored with a paint of the same color as the background 1 (green in this embodiment), or a paint of the same color as the background 1 or a diluted solution thereof is used. As the background 1, it is conceivable to use paper colored with the above coating agent applied to the upper arm portion 2, but the present invention is not limited thereto. The background 1 only needs to be colored with the same color as the coating agent, and those colored with the same color by other methods such as printing may be used.

[0018] Further, the coating agent may be directly applied to the upper arm portion 2, or may be applied in a state where a white cotton cloth or the like is wound around the upper arm portion 2 so as to be easily colored.

[0019] FIG. 1(C), FIG. 2(A) and FIG. 2(B) are diagrams showing the process of applying the coating agent. As shown in the figure, in the upper arm portion 2, it shows that the area of the coated portion 2A coated with the coating agent gradually becomes wider and the area of the non-coated portion 2B not coated with the coating agent becomes narrower. The photographing by the camera is continued until the non-coated portion 2B is mottled (coating unevenness) and the non-coated portion 2B almost disappears, as shown in FIG. 2(B).

[0020] Next, the video of the upper arm part 2 taken by the camera is imported into a computer capable of performing image processing such as a PC, and a transparency effect process is executed. In the transparency effect process, as shown in FIGS. 3 and 4, the computer makes the part (green part) colored by the coating agent in the video of the photographed upper arm part 2 transparent and superimposes it on the background image 4. The above-mentioned transparency effect process is a process of making a part of an image transparent based on a specified color or luminance and synthesizing another image there. In the present embodiment, a chroma key that makes the image transparent based on the specified color is used as the transparency effect process, but a color key that makes the image transparent based on the luminance of the specified color or a luminance key that makes the image transparent based on the specified luminance may also be used. Note that the transparency effect process is arbitrary as long as it is generally recognized and is not limited.

[0021] When the transparency effect process is executed, the background 1 colored in the same color as the coating agent is made transparent and disappears, and the background image 4 on the back side is displayed. Before applying the coating agent, an image in which the upper arm part 2 can be seen in front of the background image 4 is obtained. When the application of the coating agent is started using the aerosol container 3, the coated part 2A of the upper arm part 2 coated with the coating agent is made transparent and disappears, and the background image 4 on the back side is displayed. A video can be obtained in which the coated part 2A that becomes transparent and disappears gradually spreads, and finally the upper arm part 2 almost disappears and becomes invisible.

[0022] The above video is shown and distributed at storefronts, event venues, the Internet, etc. as a video showing the effect of the pest repellent on pests. General consumers who watch this video can intuitively understand the effect that pests cannot be detected as if the place where the pest repellent is applied is transparent. And general consumers can be careful to apply the pest repellent so that coating unevenness does not occur as much as possible when applying the pest repellent.

[0023] Note that the present invention is not limited to the above-described embodiments, and modifications, improvements, etc. can be made as appropriate. In addition, the materials, shapes, dimensions, numbers, arrangement locations, etc. of the respective components in the above-described embodiments are arbitrary as long as the present invention can be achieved and are not limited.

[0024] According to the above-described embodiment, a video of the upper arm 2 from before applying the coating agent to after applying the coating agent was taken, and a transparency effect process was executed on the taken video, but it is not limited thereto. For example, as shown in FIG. 5(A), a transparency effect process may be executed on a still image with many non-coated portions 2B of the coating agent (a lot of uneven coating) and a still image with few non-coated portions 2B of the coating agent, respectively. Then, as shown in FIG. 5(B), an image in which two still images subjected to the transparency effect process are arranged may be shown or distributed at a storefront, an event venue, or on the Internet.

[0025] According to the above-described embodiment, the upper arm 2 was arranged and photographed in front of the background 1 colored green, but it is not limited thereto. If the arrangement position of the upper arm 2 on the image is known, an image obtained by cutting out only the upper arm 2 may be subjected to a transparency effect process and superimposed on the background image 4.

[0026] In the above-described embodiment, the upper arm 2 of a person is used as the object, but it is not limited thereto. Any object that can be colored may be used, and for example, a doll or the like may be used.

[0027] In the above-described embodiment, a coating agent composed of paint is applied to the upper arm 2 as the object to color it, but it is not limited thereto. For example, an object may be constituted by a material that changes color when a liquid (for example, water) is applied thereto (for example, waste paper that turns black when wet with water), and a liquid such as water may be used as the coating agent and applied to the object.

[0028] In the above-described embodiment, a video of the object from before applying the coating agent to after applying the coating agent is taken, and a transparency effect process is performed on the video, but it is not limited thereto.
