Abstract

In a conventional method of organizing image data taken by a digital camera, only information on the date and time and position are attached to each data, without acquiring information related to the content of the data. Therefore, positional information is obtained and attached to the data of image or text, and when storing the data, information related to the position is acquired based on the positional information and stored in association with the data. Related information is also acquired when the data is viewed. The size of a data file is reduced with a decreased size of information attached to the file. Acquiring the latest information as well as previous information upon viewing the data is possible, since information related to the position of data creation is available in addition to information on the date and time and position, when storing and viewing the data. The acquired information enables detailed categorizing, searching and rendering of data.

Description

technical field

[0001] The present invention relates to methods of obtaining additional information based on user-generated data. Background technique

[0002] In recent years, opportunities to take pictures using digital cameras or cameras attached to mobile phones have gradually increased. Photography can be easily performed using these information processing devices, but on the other hand, the amount of image data is increasing, making it difficult to organize and classify.

[0003] In response to this problem, some people have studied the method of adding information such as shooting date / time to the captured image. In digital cameras, in order to store various information such as shutter speed and date / time, the format called Exif is widely used. use. In addition, some image formats provide an area where additional information such as comments can be stored.

[0004] In addition, there is also a method of acquiring positional information represented by latitude and l...
