Information Science
[Introduction to Contents]
[Book Contents]
In order to develop human resources who will take charge of multimedia science and multimedia system technology in the future, it is desirable to acquire the foundation of the important elemental technology group widely and firmly.
And over the past 20 years, there has been a great deal of personalization in multimedia systems.
With these in mind, this book is structured as follows.
(1) Human factors such as hearing, voice, and vision and quantification methods
(2) Analog technology useful for understanding current digital technology
(3) Fundamentals of signal digitization, digital representation of sound signals in CD
(4) Information compression signal processing technology that uses relatively similar technical elements in both audio signal processing and image signal processing
(5) Interface and VR technology that support interaction between humans and machines
[Features of books]
Regarding analog technology, we emphasize the relationship with current digital technology, and we are aware that revolutionary changes are unlikely to occur in the basic technology used for practical systems, and we describe the necessary basic technology in detail.
In addition, digital technology is described as systematically as possible, and in order not to fall into abstract theory, examples of actual systems using standardized technology are shown for each item of elemental technology.
Also, for a wider understanding, the application of each technology to sound signals first and then to image signals is described and compared.
It was also decided that the exercise questions required for the textbooks should be in the form of report tasks, and that tasks slightly beyond the scope of this paper will guide further technical exploration.
For this reason, we have chosen to give priority to relatively accessible books rather than articles.
