| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | With the widespread use of mobile phones equipped with a decoder, two-dimensional code represented by QR code is widely used in recent years.But there are some problems in the current QR code, for example, the amount of data that can be stored at a maximum is about 3KB and recognition accuracy decreases with an increase in the volume of data that is stored.There are studies which increase the information density of the two-dimensional code by states of the two-dimensional code increase.In this paper, we aim to expand the capacity of the data by using gray scale colorizing QR code.In addition, we also propose gray scale colorizing QR code that the conventional decoder can read the information that is stored and it is possible to embed the new information. | |
