Published Patent Publication (A) Japanese Patent Laid-Open No. 2015-139943

The photograph had the following drawbacks for visually impaired people.
The photograph was a smooth surface, and visually impaired persons could not feel it even when touched with their hands. In addition, for the decorative plate (name of invention) of <Patent Document 1>, by expressing the photograph part and decorative part of the plate in three dimensions, the event is more vividly impressed by the viewer. It is intended to increase the value as a souvenir, etc., but for visually impaired people, although it can detect the bulging part of the sheet-like material, it cannot sense the contents such as the individual contours of the target It was.
The present invention has been made to eliminate the above drawbacks.

The surface of the photograph is processed so that it can be felt by touching it, and the processed three-dimensional pattern becomes a tactile pattern. Become.

Use a repair material, such as copying the surface of a photograph to a negative film, clearly distinguishing the periphery of the person's image on the copied film from the background and equipment, and providing a separation width between the person image and the person image. The outline is clarified in terms of shape, for example, by using a personal computer image processing technique.

The modified film is made of a polyester film or the like as a support (reference numeral 3), and a photosensitive synthetic resin layer of an appropriate size, such as a total thickness of about 1 mm and an area A4 size, laminated with a photosensitive synthetic resin layer (reference numeral) Overlay the surface of 2).

After superposition, exposure is performed for a required time from the side of the film using an exposure apparatus.

After the exposure, the film is removed from the synthetic resin plate, the synthetic resin plate is developed using water, and further washed with water. The exposure varies depending on the black, transparent, light and shade, color, and color tone of the film surface, and the depth of elution by the cleaning treatment also varies on the surface of the synthetic resin plate that has been cleaned. The synthetic resin plate formed with the difference in level and the concave groove (reference numeral 6) caused by this difference is obtained as a relief pattern made of synthetic resin as a desired generation state by modifying the film surface. Become. With respect to the portion that becomes the step bottom (reference numeral 5) after cleaning, a step of about 0.7 millimeters is formed around the outline of the person image, and the groove between the person image and the person image has a concave groove width of 2 to 5 millimeters and a concave shape. It becomes a concave groove (symbol 6) with a groove depth of about 0.7 mm, and the upper surface of the step (symbol 4) surrounded by the boundary step and the concave groove (symbol 6) can be touched and felt as the outline of the person image. It becomes a knowledge photograph (FIG. 1 and code | symbol 1).

Next, numeric numbers in braille are attached in order to the contour unit surface of the image of two or more contour images generated in the tactile photograph. A table that includes the numbers and full-length ink and Braille corresponding to the number in Braille is attached as an attachment.

By comparing the Braille display number attached to the contoured person image with the Braille number and Braille name of the attached material, the person image of the tactile photograph can be clearly identified.
The present invention is a tactile photograph having the above configuration.

By making a photograph that cannot be felt by touching it into a relief-like tactile pattern using a synthetic resin plate, the visually impaired can also feel the outline pattern similar to the photograph, and It becomes possible to know and remember the department.

By comparing this tactile photo with the Braille number and name of the attached material, the visually impaired can independently recall the entire situation and individual person at the time of taking the photo.

The tactile photographs according to the present invention allow the visually impaired to recall their contents independently, and the family members, together with the original photographs, together with the visually impaired, share a common topic. You can talk to each other.

About this tactile photograph, in the case of a human image, each name can be confirmed by comparing and tactilely comparing the Braille display number attached to each outline with the attached Braille display number and name table. In addition, the voice guide using the recording device can reproduce and listen to the atmosphere and name at the time of shooting, thereby increasing the information of memories.

Of the video footage, natural scenes such as cityscapes and mountain scenery are modified and modified so that they can be felt with the touch. Can be explained.

Use textbooks, various pictorial books, encyclopedias, etc. for photo parts, designs, and picture parts as tactile designs such as synthetic resin boards, commentary using Braille, and voice guidance using recording equipment. In this way, it is possible to come into contact with tactile and auditory scenes and situations.

FIG. 3 is a plan view of a copy of a tactile photograph according to the present invention. It is AA sectional drawing of this invention. It is BB sectional drawing of this invention.

Hereinafter, modes for carrying out the present invention will be described.
Process and use synthetic resin plates so that you can feel the image of the photo by touching it. The processed 3D design is a tactile photograph that can be felt by hand for those who are visually impaired.

Copy the photo to the required size negative film such as A4 size.

Use a repair material to modify the image on the surface of the film, such as separating the periphery of the copied person image from the background or equipment, and providing a separation width between the person image and the person image. Make the outline of the image clear.

The modified film is superposed on the surface of the resin layer of the ultraviolet-reactive synthetic resin plate having a total size of about 1 mm in which the ultraviolet-ray-reactive synthetic resin layer is laminated using the polyester film as the support, and a necessary size such as A4 size. .

After superposition as described above, ultraviolet rays are irradiated from the surface of the film for a required time using an ultraviolet irradiation device.

After the ultraviolet irradiation, the film is removed from the synthetic resin plate, the synthetic resin plate is developed using water, and further washed with water. The ultraviolet rays applied to the synthetic resin plate cause a difference in the amount of irradiated light depending on the black, transparent, light and shade, color, and color tone of the film surface. There is also a difference in depth. The synthetic resin plate formed with steps and concave grooves after water washing caused by this difference becomes a relief made of synthetic resin as the expected generation by correcting the film surface, and 0.7 mm around the person image The level difference, the groove between the person image and the person image becomes a groove shape forming a contour with a concave groove width of 2 to 5 mm and a concave groove depth of about 0.7 mm, and the contour can be touched and felt by hand. It becomes a tactile pattern that can be done. This tactile pattern becomes a tactile photograph that can be felt by the hand of the handicapped.

Next, numbers in braille display are affixed to the contour unit surface of the human image of the tactile photograph in an appropriate order. In addition, a table with numbers and full name Braille corresponding to the Braille display numbers is attached as an attachment.

The person in the tactile photograph can be clearly identified by tactile / contrast the Braille display number attached to the person image with the outline, the Braille number and the name of the attached material.
