In this paper, the method to make lossless image compression that holds considerable part of total volume of mobile game has been proposed. To increase the compression rate, we compress the image by Deflate algorithm defined in RFC 1951 after reorganize it at preprocessing stage before conducting actual compression. At the stage of preprocessing, we obtained the size of a dictionary based on the information of image which is the feature of Dictionary-Based Coding, and increased the better compression rate than compressing in a general manner using in a way of restructuring image by pixel packing method and DPCM prediction technique. It has shown that the method increased 9.7% of compression rate compare with existing mobile image format, after conducting the test of compression rate applying the suggested compression method into various mobile games.

If game images use colors improper for certain ages, the characteristics of games disappear, and the efficiency of image expression drops. thus a study in color is very important. Nevertheless, there is a lack of research on this subject. In this study, we investigated the difference of color of game images according to users. User group is divided into all users and users over 18 years old. Among the rank of games,10 each from games for all ages and games for non-teen-rated are selected, and the game-playing images are taken as snapshots to have 100 each images each, A total of 2000 images were extracted and the mean values of RGB and HSB of each game were obtained and independent sample t test was performed. The results showed that the RGB color values between the two users were significantly significant. In the future, it is expected that it will be helpful in color selection when developing psychotherapy games and emotional games using color psychology. Furthermore, we will use color image scales to express colors as adjectives, analyze colors in a variety of ways, and investigate the difference in color of game images in each country.

In this study, we verified the relationship of major variables that affect brand awareness, brand image and brand loyalty in the game industry. Six hypotheses for five variables were established and tested using K-BPI data. Distribution accessibility had the only significant effects on brand awareness, whereas marketing communication and distribution accessibility had significant effects on brand image. Only the brand image had a significant effect on brand loyalty. Brand communication to improve brand image and distribution to promote experiential marketing seem to be important.

The paper discusses the issue of reality related to interaction between users and electronic figures that mediate by online game system. MMORPG(Massively Multiple Online Role Playing Game) has been known as virtual world that physically and electronically interconnect users and mechanical elements over huge area. Already game items have became a kind of reality for some users long time ago. How these figures could have been regarded as realities? It suggests to take place the temporality of practice around game world. Tremendous practices of human and machines produce their relations and these relations are reinforced self-referentialy. They could constitute their time-space frame that be situated a figure as the something in it.

A game starting, the process of running has some loading steps. In general, textures use corresponding images saved externally and the file format of images affects the loading time of game. We propose some ideas for the texture using method by comparison with loading time according to some file formats.

3D 게임 엔진 중 그래픽 엔진이 차지하는 중요도는 다른 엔진들보다 월등히 높다. 그래픽 엔진에는 여러 가지 필요한 요소들이 들어가는데, 지형을 만들어내는 것 역시 캐릭터를 제작하는 것만큼이나 중요한 역할을 한다. 3D 지형이 좀더 현실과 흡사하기 위해서는 실세계와 유사한 가상의 세계를 만들어야 한다. 3D 지형을 만드는 방법은 여러 가지가 있으나 자신이 원하는 지형을 직접 만들어서 이를 3차원으로 바꿔서 게임 엔진에서 사용할 수 있고, 또한 게임 엔진 내부에서의 최적화를 위해서는 가장 기본적으로 쓰이는 그레이 스케일 이미지를 사용한 높이 맵으로 지형을 생성하는 게 유리하기 때문에 본 논문에서는 그레이 스케일 이미지를 이용한 지형생성기를 개발한다.

A new compressed image format is proposed to use a large size of image in mobile games without the constraints of hardware specifications such as memory amount, processing power, which encodes each block of a large size image in scan line order. Using the experiments, we show the effectiveness of proposed method compared with a general PNG in terms of compression ratios and required memory in decoding processes. Also, the loading delay can be reduced by decoding only the displaying area of a large image in run-time.

The recent Neural Network technique has shown good performance in content generation such as image generation in addition to the conventional classification problem and clustering problem solving. In this study, we propose an image generation method using artificial neural network as a next generation content creation technique. The proposed artificial neural network model receives two images and combines them into a new image by taking color from one image and shape from the other image. This model is made up of Convolutional Neural Network, which has two encoders for extracting color and shape from images, and a decoder for taking all the values of each encoder and generating a combination image. The result of this work can be applied to various 2D image generation and modification works in game development process at low cost.

본 연구에서는 게임 배경과 게임 캐릭터의 효과에 대해서 나타낸다. 먼저 3개의 캐릭터 이미지를 주 캐릭터 로 만들 이미지에 합성기법을 적용하여 캐릭터들을 합성한다. 합성하여 만든 캐릭터와 다른 캐릭터의 모양과 형태에 맞게 알맞은 배경 색상으로 만들고, 각 캐릭터의 크기, 원근, 모양, 색상에 따라 효과를 적용한다. 따라서 게임 콘텐츠를 제작하는데 정지 영상으로 표현하여 캐릭터 애니메이션과 장면에 맞는 사운드를 삽입하여 게임 콘텐츠로서 시각과 청각과 움직임이 있는 게임 캐릭터를 제작한다. 특히 배경색, 캐릭터의 번개 및 라이팅 효과색상 같은 것에 관심을 갖고 제작하여 앞으로 게임 콘텐츠의 배경과 캐릭터 효과를 제작하는데 모션그래픽을 이용하여 간단하게 제작 할 수 있음을 나타내었다.
