Abstract

<P>PROBLEM TO BE SOLVED: To provide a sheet for identifying conspicuous equipment under a color environment which can be provided as a standard background environment when testing the conspicuousness of an object in a train space. <P>SOLUTION: In the sheet for verifying the conspicuous equipment under the color environment, the number of pixels of a picture of a passenger 3 sitting on a long sheet in the train is reduced and respective colors of the number of pixels are averaged to prepare the sheet. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a sheet for confirming equipment that is visually conspicuous under a color environment such as equipment arranged in a train.

  In order to make the handrails installed in the train stand out, it depends on the contrast with the background color environment. For example, yellow stands out when black is used as a background, but does not stand out when white is used as a background.

  Note that image information in the measurement process is described in detail in Non-Patent Document 1 below.

Note that a pixel means the smallest pixel that can be handled in image display, and is a shortened form of a picture element.

  However, since the visual environment in the train is greatly influenced by the clothes of passengers, it is difficult to determine uniquely. Therefore, if a unique design can be determined as a typical pattern of the clothing environment of passengers in the train during commuting and attending school, the ease of conspicuousness of various facilities, including handrails in the train, can be compared with each other. It becomes possible to examine and narrow down excellent ones.

  In view of the above situation, the present invention is visually conspicuous under a color environment that can be used as a standard background environment when testing the visual conspicuousness of an object in a train space. An object is to provide an easy-to-confirm sheet for equipment.

In order to achieve the above object, the present invention provides
[1] In the sheet for checking visually conspicuous equipment in a color environment, the number of pixels in the photograph of passengers seated side by side on the long seat in the train is dropped, and each color of this number of pixels is averaged. It is characterized by creating.

  [2] In the confirmation sheet for visually observable equipment under the color environment described in [1] above, the mesh interval for averaging the number of pixels is about 50 mm.

  [3] In the sheet for confirming visually observable equipment under the color environment described in [1], the mesh interval for averaging the number of pixels is about 100 mm.

  ADVANTAGE OF THE INVENTION According to this invention, a passenger's clothes can fully be reflected as the visual environment in a train, and the visually conspicuous installation in a color environment can be determined.

  The sheet for checking visually conspicuous equipment under the color environment of the present invention is obtained by dropping the number of pixels of the photograph of the passenger seated side by side on the long seat in the train and averaging each color of the number of pixels. create.

  Hereinafter, embodiments of the present invention will be described in detail.

  FIG. 1 is a view showing a confirmation sheet for equipment that is visually conspicuous under a color environment according to the first embodiment of the present invention.

  Confirmation sheet 1 created by averaging the color of this pixel number by dropping the mesh interval for averaging the pixel number of the photograph of the passenger 3 seated side by side on the long seat 2 in the train to about 50 mm. Got.

  In this way, when the mesh interval is averaged at about 50 mm, it is possible to obtain a visually-conspicuous equipment confirmation sheet in a color environment that sufficiently reflects the clothes of passengers as the visual environment in the train. did it.

  FIG. 2 is a view showing a sheet for confirming equipment which is visually conspicuous under a color environment according to the second embodiment of the present invention.

  In this embodiment, as in the first embodiment, the mesh interval for averaging the number of pixels of the photograph of the passenger 3 seated side by side on the long seat 2 in the train is about 100 mm (the face width is one frame). ) To obtain the confirmation sheet 11 created by averaging the colors of the number of pixels.

  Even in this example, somehow, it was possible to obtain a visually-conspicuous facility confirmation sheet in a color environment that reflects the clothes of passengers as the visual environment in the train.

  Here, it also means a partial simulation of the visual environment of elderly and visually impaired people with reduced vision. It is possible to change the blurring method depending on the difference in the number of pixels, and when the age group and attributes of passengers differ greatly, standardization in the environment is also possible. As a result of the user survey, it was decided which mesh interval is optimal.

  This also makes it possible to obtain a visually confirming equipment confirmation sheet in a color environment, but it is a confirmation sheet with a slightly reduced accuracy.

  FIG. 3 is a view showing a sheet for confirming equipment that is visually conspicuous under a color environment showing a first comparative example of the present invention.

  In this first comparative example, the number of pixels of the photograph of the passenger 3 seated side by side on the long seat 2 in the train is averaged by dropping the mesh interval for averaging to about 150 mm, as in the above example. Thus, a confirmation sheet 21 created was obtained. The accuracy of the check sheet 21 is low as a check sheet for facilities that are visually conspicuous in a color environment.

  The results of the user survey were as follows.

  As a result of showing 64 kinds of cloths (sheets) to 64 users, about 50 mm mesh was the highest evaluation (“59%” was selected) when asked “What is suitable for visibility evaluation”. About 50mm mesh (1st example) and about 100mm mesh, the ratio of "Easy to understand border" and "Natural" to "Very difficult to understand" and "Very unnatural" respectively is less than 10% there were. On the other hand, in the case of about 150 mm mesh, it was 20% or more.

  As described above, the number of pixels of the photograph of the passenger 3 seated side by side on the long seat 2 in the train is dropped, and the color of each pixel is averaged to use the confirmation sheet created in the color environment. The color of equipment that is visually noticeable can be determined.

  In addition, this invention is not limited to the said Example, Based on the meaning of this invention, a various deformation | transformation is possible and these are not excluded from the scope of the present invention.

  The visually recognizable equipment confirmation sheet under the color environment of the present invention can be used as a tool for determining the color of equipment in a train.

It is a figure which shows the confirmation sheet | seat of the equipment which is visually conspicuous in the color environment which shows 1st Example of this invention. It is a figure which shows the confirmation sheet | seat of the equipment which is visually conspicuous in the color environment which shows 2nd Example of this invention. It is a figure which shows the confirmation sheet | seat of the equipment which is visually conspicuous in the color environment which shows the 1st comparative example of this invention.
