  • Picture books, as a genre, are characterized by conveyance of ideas through linguistic texts, visual texts, and the complementary interactions between them. The writer of a picture book develops and delivers his or her ideas with textual contents written in a unique style, while the artist conveys the writer's ideas through pictures where things, objects, and figures are imbued with various emotions. Understanding a picture in a picture book requires an understanding of both the structure shown on the surface and the underlying structure that adapts and visualizes the philosophy and ideas of the writer. In light of the discussion above, this study proposes a method to help librarians improve their understanding of visual literacy for picture books, as visual literacy is required for the provision of readers' advisory services regarding picture books. This method, which is based on behavioral psychologist Rudolf Arnheim's theory of visual thinking, is expected to help librarians write picture book reviews or other secondary materials.

  • Wittgenstein presents so-called picture theory in the Tractatus Logico-Philosophicus. What is, then, the point of the picture theory? What are the philosophical problems which the picture theory tries to solve? In this paper, I will endeavor to show that the object of a picture is different from the sense of a picture, that the representing relation is different from the projective relation, that picture theory is applied to composite propositions as well as elementary propositions and that on the one hand the basic problems that picture theory tries to solve are problem of theory of meaning and that of theory of truth, but on the other hand the more important problem is what Wittgenstein calls "the mystery of negation." From these discussions, we can see that it is not correct at all to interpret that the picture theory in the Tractatus Logico-Philosophicus is nothing but an analogy which does not have a significant content.

  • Consumers changed to the subject to produce a digital contents as data transmission technique is advanced and a digital machine is diffused variously. Users are interested greatly in a user creative movie (UCM) production among various online contents. The UCM production method which uses the music and picture is the method that users make the UCM more easily. However, the UCM production service has the problem that any association does not exist in the music and picture and that the picture changes according to fixed time interval without the relation at a music rhythm. To solve this problem, we propose the UCM production method which uses a music analysis and picture analysis in the paper. A music analysis finds a picture change time according to the rhythm and a picture analysis finds the association of the picture. A music analysis finds strong parts of the sound which uses Root-Mean-Square (RMS). And a picture analysis classifies the picture as a scenery picture and people picture which uses structure simplicity of the picture(SSP) and face region detection. A picture analysis got correct result of 86.4% in the experiment and we can finds the association at each picture and arranges the sequence which the picture appears. Therefore, if we use a music and picture analysis at the UCM production, users may make natural and efficient movie.

  • This research is based on the design of pictures in picture books, and the spatial representation of illustrations in the picture books contains the significantly important objective. Various texts, pictures, spaces, etc. in a picture must have the operator's various editing skills so that spatial arrangement is made smoothly.In this paper, the characteristics of spatial expression of design in picture books are derived by analyzing several examples of paintings and studies on classic picture books. First, the fusion of picture and text, that is, that both picture and text convey spatial information together as elements of the screen. Second, as a characteristic of the coherence of the space design in picture books, the story and content must be smoothly connected when reading the book. Third, when expressing a space, the creator should utilize the strengths and weaknesses of each other between abstract and conceived spatial expressions as needed. Fourth, as a symbolic feature of picture book spatial expression, it can be seen that many symbolic expression techniques are applied to the spatial expression of picture books according to the semiotic principle, which greatly improves the cognitive efficiency of reading picture books. The fifth characteristic is that the spatial expression of an excellent picture book has excellent interesting element, rich design means, and interestingly conveys screen contents and screen format to readers. In this research, it is thought that designers and artists should guide the creation within a spatial framework as designing picture books, thus greatly improving the efficiency of the creation process, while also provide a reader-centered visual Interesting experience.

  • The purpose of this study is to look into the meaning of Hong Seongchan who has become the first generation picture book writers in the history of Korean picture books by considering the works of the picture book author 'Hong Seongchan', the characteristics of pictures and the artist's spirit. The career that he took up from 1955 as an illustrator to 2012 when the final picture book was published is in line with the developmental process of Korean picture books. He consistently devoted himself to publishing illustrations from the days when his job as an illustrator was not noticed to the days when he finished his life as a picture book writer through his full-length period. As a result, he built a unique world of works, such as the reproduction of Korean images and emotions through complete historical research. His strong illustration spirit and craftsmanship during his lifetime became the basis of the birth of a professional group called a full-time picture book writer, and Hong Seongchan became the first generation picture book writers in the history of Korean picture books.

  • This thesis intends to grasp the degree of utilization of visual images by understanding the relational properties between picture and letter and considering the children as users, through the analysis of currently published books of English vocabulary for children. Accordingly, the types of picture used in the books of English vocabulary for children, the degree of utilization of picture, combination types of picture and letter, and semantic consistency of picture and letter are reviewed. As a result of analysis, the degree of utilization of picture is high in general, in order of illustration, cartoon, and the mix of illustration and cartoon. In the combination form of picture and letter, the degree of utilization appears in order of picture plus vocabulary, letters without illustration, and pictorial symbol. In particular, the higher semantic consistency of picture and letter, it is effective in learning, however, semantic consistency is low, generally. Pictorial symbol type shows the frequency of the highest combination type in the five groups of higher semantic consistency. In conclusion, the presented types of picture and letter, shown in the currently published books of English vocabulary for children, are similar types by the publishing companies, thus, effective design research should be required based on diverse levels of children.

  • This study presents a way to design picture books that allow children to experience indirectly through realistic media at home and educational institutions for children whose direct experiences and activities are reduced offline in the post-COVID-19 era. The development and popularization of realistic media such as AR continues to be grafted and developed in the picture book field, and the advantage of this picture book is that children at the stage before learning letters can feel the story and character situation of the book through the experience of AR and QR animation in the picture book. In this process, you can get access to imaginary areas that can not be experienced in flat-panel illustrations with spatial animation to help improve the scalability and literacy of the story contained on the page. Children's education through realistic animation can increase the learning effect and needs to continue after COVID-19. Therefore, by presenting the process of viewing and experiencing picture books using AR and QR, the result of the study suggests that the design process of realistic picture books is not just a combination of technology, but a process of expanding children's perception and imagination. This study aims to find out how visual perception is designed differently by analyzing the differences and characteristics of each animation design, focusing on the AR and QR picture book "Where am I?" published by the researcher, and to contribute to the active introduction and development of realistic animation in the field of children's picture books and education.

  • Conventional MSE or PSNR based methods for objective picture quality assessment of moving picture coder are not well correlated with subjective human evaluation. In recent years, the design of better objective quality assessment has attracted much intention and several picture quality metrics based on the properties of Human Visual System has been proposed. This paper proposes new metric which is appropriate for objective picture quality assessment of block based moving picture coder by considering frequency sensitivity, inter-intra channel masking and several distortion artifacts caused by block based coding. The experimental results show that the proposed method is good correlated with subjective assessment.
