Method and system for transforming adaptively visual contents according to terminal user's color vision characteristics

Abstract

Disclosed are a method and a system that adaptively transform visual contents inputted from a network, in accordance with the visual characteristics of a terminal user. A visual characteristics descriptor that describes the information of the user visual characteristics in a predetermined format is proposed. The descriptor includes the information of the color vision deficiency type and the color vision deficiency degree. The color vision deficiency may be described in numerical degree or textual degree. The invention adaptively transforms visual contents differently in accordance with the color vision deficiency type.

Description

TECHNICAL FIELD [0001] The present invention relates to a method and a system for transforming visual contents and, in particular, to a method and a system for adaptively transforming visual contents in accordance with the color vision characteristics of a user. BACKGROUND ART [0002] The MPEG-21 is being established as the next generation standard for a multimedia framework by MPEG (Moving Picture Expert Group), which is a Working Group of ISO / IEC JTC 1 / SC 29. The goal of MPEG-21 is to realize a multimedia integration framework capable of freely and easily using multimedia contents despite the wide-range characteristics of networks, terminals and users, existing under various environments, by unifying the standards of the existing MPEGs or other standardization groups. The digital item adaptation part of the MPEG-21, Part 7 relates to adaptively transforming the multimedia contents (or digital items) in accordance with the characteristics of networks, terminals (video display device...

Benefits of technology

[0011] It is an object of the present invention to provide a user Wraith a color vision deficiency with the semantic information of visual contents that corresponds to a normal user regardless of the color vision deficiency type and without any separate equipment.

[0012] It is another object of the present invention to provide a user with a color vision deficiency with the semantic information of visual contents that corresponds to a normal user in accordance with the digital items.

[0019] As described above, in accordance with the present invention, a user with a color vision deficiency is able to receive semantic information from visual contents that are substantially identical to that of a normal user without any separate equipment, whereby the user with a color vision deficiency is able to freely and conveniently use multimedia contents. In addition, the present invention is applicable to the digital item adaptive part of MPEG-7 and MPEG-21, which are the international standards of media.

Problems solved by technology

However, in this paper, only an algorithm capable of simulating the color vision characteristics of users with the color vision deficiency is disclosed.

However, this method urges the contents manufacturers to use limited number of colors, thereby restricting the creativity of the manufacturers and possibly inducing the inconvenience and monotony in the process of recognizing the color information for normal users.

Therefore, this method is difficult to satisfy the requirements of various users.

Thus, such a process performed in the contents manufacturing step has a disadvantage in that it is impossible to adaptively transform the already existing contents.

However, this method applies a filter to a monitor and has a disadvantage in that it is impossible to perform a transformation in accordance with the contents if a plurality of digital items, i.e. a number of images, exist in a screen.

Furthermore, it is a burden to purchase a specially manufactured CRT monitor in order to implement this function.

However, the process for adaptively transforming visual contents in accordance with the color vision characteristics of humans with a color vision deficiency is very complicated.

Moreover, the method does not allow humans with a color vision deficiency to conceive the adaptively transformed visual contents, but allows humans to merely discriminate the visual contents.

Nevertheless, no method for treating color vision deficiencies exists at present; thus, this study has been commissioned to research a new scheme for treating color vision deficiencies.

It is medically impossible to make humans with a color vision deficiency see original colors.
