Patent number: 8879859Abstract: An apparatus for generating/decoding an animated image code, and a method thereof. The animated image code frame includes an image code frame which is divided into code cells expressing minimum unit data, and in which the minimum unit data is expressed in an area located inside the code cells and is formed by combining one or more color, gradation, and patterns; and a design layer which is formed by combining color or gradation used in the image code frame and color or gradation distinguishable on the basis of a threshold value, and which is displayed by overlapping the frame image. By utilizing changes in respective animated frames, an animated image code can be generated and decoded in which motion can be expressed by using a display medium.Type: GrantFiled: April 17, 2013Date of Patent: November 4, 2014Assignees: Colorzip Media, Inc., Colorzip Technology Co., Ltd.Inventors: Cheol Ho Cheong, Sang Yong Lee

Patent number: 7978911Abstract: Provided is a method of classifying colors of a color based image code. The colors of each cell forming the color based image code are classified by sampling a predetermined number of pixels from each cell and then applying a max channel based clustering method, a white balance based color clustering method, a single-linkage algorithm based color classification method, a K-means algorithm based color classification method, or the like. Accordingly, the colors of an image code can be accurately recognized despite of a color distortion due to characteristics of a camera, a printing medium, etc.Type: GrantFiled: June 18, 2007Date of Patent: July 12, 2011Assignees: Colorzip Media, Inc., Colorzip Technology Co., Ltd.Inventors: Cheol Ho Cheong, Tack Don Han, Sang Yong Lee

Patent number: 7792371Abstract: A method and device for generating and decoding an image code without a direction finder pattern are provided. In the method of generating an image code, a two-dimensional image is generated by encoding the configured basic information and the error correction information, and disposing the encoded basic and error correction information in predetermined regions, respectively. It is determined whether the two-dimensional image can be decoded for directions which are different from a basic direction of the two-dimensional image, respectively, and the two-dimensional image is output as a physical or electronic image code when a result from decoding for the directions which are different from the basic direction of the two-dimensional image is the same as a decoding result for the basic direction, or when decoding cannot be performed for a direction which is different from the basic direction.Type: GrantFiled: November 2, 2006Date of Patent: September 7, 2010Assignees: Colorzip Media, Inc., Colorzip Technology Co., Ltd.Inventors: Jae Won Ahn, Cheol Ho Cheong, Tack Don Han, Sang Yong Lee
