JP4964633B2 - Visually conspicuous equipment confirmation sheet under color environment - Google Patents

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 the image information definitive the measurement process is described in detail in Non-Patent Document 1.
Note that the pixels (pixel), refers to the smallest pixel that can be handled in the image display, which is short for picture Jer main cement (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.
The present invention is, in view of the above situation, in testing visual conspicuous ease of certain objects in the train in space, can be provided as a standard background environment, visually under color environment An object is to provide a sheet for checking a conspicuous facility.

In order to achieve the above object, the present invention provides
[1] In a sheet for checking visually conspicuous equipment in a color environment, a photograph of passengers seated side by side on a long seat in a train is divided into meshes, and each mesh is defined as one pixel. And the colors in each mesh are averaged to obtain the color of each pixel .

[2] In confirmation sheet visually conspicuous equipment undercolor environment described in [1], wherein the spacing of the mesh is about 50mm in actual size of the imaging target.
[3] In [1] above confirmation sheet visually conspicuous equipment undercolor environment according to, characterized in that spacing of the mesh is about 100mm in actual size of the imaging target.

  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.

According to the color environment of the present invention, the visually conspicuous facility confirmation sheet divides a photograph of a passenger seated side by side on a long seat in a train into meshes, and each mesh is defined as one pixel. And the colors in each mesh are averaged to obtain the color of each pixel .

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.
Interested in passenger 3 seated side by side on the long sheet 2 in the train is divided as mesh spacing is about 50mm in actual size of the imaging object, dropped the number of pixels photo each mesh as one pixel, in each mesh The confirmation sheet 1 was obtained by averaging the colors of these to obtain the color of each pixel.

Thus, the passenger photo divided by mesh between 隔約 50 mm, in the case where the color in each mesh were averaged, sufficiently reflect the clothing of a passenger as a visual environment in the train, visual undercolor environment It was possible to obtain a sheet for confirming the equipment that was easily noticeable.
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 spacing pictures of long passenger 3 seated side by side on the sheet 2 is about 100 mm (face width of 1 frame) in the actual size of the imaging target in the train divided so, dropping the number of pixels photo each mesh as one pixel, to obtain a confirmation sheet 11 created by by averaging the color in each mesh to the color of each pixel.
Even in this example, somehow it was possible to make a visually-conspicuous equipment confirmation sheet in a color environment that reflects the clothes of the passenger as the visual environment in the train, but the accuracy is somewhat reduced. It became .

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.
Figure 3 is a diagram illustrating a confirmation sheet visually conspicuous equipment undercolor environment showing the ratio Comparative Examples of the present invention.

In this specific Comparative Examples, similarly to the above embodiment, dividing the photograph passenger 3 seated side by side on the long sheet 2 in the train as the mesh spacing of about 150mm in the actual size of the imaging target, each mesh As a pixel, the number of pixels in the photograph was reduced, and the color in each mesh was averaged to obtain the color of each pixel, thereby obtaining a confirmation sheet 21 created. 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.
The results showed the user 64 people in three types of confirmation sheet, "as appropriate as for visibility evaluation" Ide question with, about 50mm mesh was higher most evaluation (59% selected). In the case of about 50 mm mesh (first example) and about 100 mm mesh (second example) , “intelligibility of human boundary” and “naturalness” are “very difficult to understand” and “very unnatural”, respectively. The percentage was less than 10%. On the other hand, in the case of about 150 mm mesh (comparative example) , it was 20% or more.

As mentioned above, the photograph of the passenger 3 seated side by side on the long seat 2 in the train is divided into meshes, each mesh is taken as one pixel, the number of pixels in the photograph is reduced, and each mesh is taken as one pixel, the number of pixels in the photograph. , And using the confirmation sheet created by averaging the colors in each mesh to obtain the color of each pixel, it is possible to determine the color of the facility that is visually noticeable in the color environment.

  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 diagram illustrating a confirmation sheet visually conspicuous equipment undercolor environment showing the ratio Comparative Examples of the present invention.
